Bassi3These instructions apply to the following models:402 CBC - 402 SBSThe FAAC 402 automated system for swing leaf gates consists of an enbloc composed of an electric pump and a hydraulic piston which transmits drive to the leaf.The model with a hydraulic locking does not require installation of electric locks, as it guarantees mechanical locking of the leaf when the motor is not operating.The model without a hydraulic locking, requires the installation of electric locks to ensure the leaf is mechanically locked.The 402 automated systems were designed and built to automate swing leaf gates. Do not use for any other purpose.Tab. 1: Technical specifications of “402 Operator”MODEL402 CBC402 SBSPower supply voltage 230 Vac(+6%-10%) 50 (6o) Hz Rod extension speed 1.3 cm/s 1 cm/s Pump flow rate1 l/min 0.75 l/min Traction and thrust force 0-500 daN0-690 daNOperating ambient temperature -40°C - +55°CAbsorbed power 220 W Absorbed current 1 A Motor rotation speed 1400 rpm Motor winding temperature 120°C Weight 6.5 kg Type of oil FAAC HP OILProtection class IP 55Single leaf max length 1,80 m3,00 mUse frequency55 (cycles/hour)4To ensure a correctly operating automated system, the structure of the existing gate or gate to be built must satisfy the following requirements:•Max length of leaves according to the dimensions of Table 1 on page 3.• A strong and rigid leaf structure.•Smooth, uniform leaves movement, without any irregular friction during the entire travel;•Existing hinges in good condition.•Travel limit mechanical stops must be provided.We advise you to carry out the metalwork jobs before installing the automated system.The condition of the structure directly influences the reliability and safety of the automated system.Table A : Recommended dimensions for standard operatorsc = The effective rod stroke is shorter than the maximum stroke, inorder to prevent the rod from reaching its stop point internally, during the opening and closing stages.(*) Rod effective stroke (**) maximum dimension1)Fasten the rear attachment on the pilaster, following the indications in Table A . Modify, if necessary, the length of the supplied attachment.Attention : To avoid compromising good operator functionality, we recommend you to respect the indicated dimensions.• For iron pilasters, accurately weld the rear attachment (ref.ባ, Fig. 6) directly on the pilaster.• For masonry pilasters, select one of the following solutions:A)appropriately lay a walling-in plate and then accurately weld the rear attachment.B)secure, with screws and expansion plugs, the rear attachment plate (ref. a, Fig.6) to the pilaster and then accurately weld the rear attachment to theplate as shown in Fig. 6.If the dimensions indicated in table A or B cannot be executed,the following must be considered in order to determine different measurements:-to obtain 90° opening of the leaf: a + b = c.-to obtain over 90° opening of the leaf: a + b < c.-lower a and b dimensions will result in higher speeds . We advise you to observe the current legal regulations;-limit the difference of the a and b dimensions to within 40 mm :higher differences will considerably vary speed during the opening and closing motion;-for reasons of operator dimensions, the minimum Z dimension is 50 mm (Fig. 4);-if the pilaster dimensions or the position of the hinge (dimension d ) do not make it possible to contain dimension a to the required size, a niche must be made in the pilaster as shown in Opening angle 90°110°a (mm)120100b (mm)120100c(*)(mm)240240d(**)(mm)705056-Lastly, remove the key and restore the power supply to the system.For any repairs, contact FAAC’s authorised Repair Centres.78The following table will help you identify and solve some particular conditions.CONDITIONGate not moving.Gate moving slowly.Gate moving jogwise.The operator is losing oil from the breather screw.The leaves stop at slow-down.Gate speed not constant.A B CD E FSUGGESTION-Check if mains power is supplied.-Make sure that the operator is not unlocked.

The devices should be used before the expiry date p rinted on the box.1.2 IntroductionVivaspin® concentrators are disposable ultrafiltration devices for the concen-tration and | or purification of biological samples. Vivaspin® 6 is suitable for sample volumes of 2 – 6 ml and the Vivaspin® 20 can handle s amples up to 20 ml. Both products feature twin vertical membranes for unparalleled speed. Vivaspin® 20 purification alternatives include a diafiltration cup that allows one step r emoval of salts and other contaminating micromolecules, and a gas pressure mode for increased flexibility and even faster p rocessing.The innovative design (US Patent No. 5,647,990, second patent pending), ease of use, speed and exceptional concentrate recoveries are the main features of the c oncentrators.The Vivaspin® 6 and 20 includes 9 different c utoffs (Molecular Weight Cutoff, MWCO):−Vivaspin® 6 & 20 3K device: 3,000 MWCO−Vivaspin® 6 & 20 5K device: 5,000 MWCO−Vivaspin® 6 & 20 10K device: 10,000 MWCO−Vivaspin® 6 & 20 30K device: 30,000 MWCO−Vivaspin® 6 & 20 50K device: 50,000 MWCO4 Instructions for Use Vivaspin® 6 and 20Vivaspin® 6 and 20 – Introduction−Vivaspin® 6 & 20 100K device: 100,000 MWCO−Vivaspin® 6 & 20 100K device: 300,000 MWCO−Vivaspin® 6 & 20 100K device: 1000,000 MWCO−Vivaspin® 6 & 20 100K device: 0.2 µmAll Vivaspin® 6 and 20 devices described above are for research use only and not for use in diagnostic procedures. The Vivaspin® 6 and 20 devices are supplied non-sterile and are for single use only.1.3 Centrifugal OperationVivaspin® concentrators can be used in swing bucket or fixed angle rotors accepting standard conical bottom tubes. In a single spin, solutions can be concentrated in excess of 100 ×. Samples are typically concentrated in10 to 30 minutes with macromolecular recoveries in excess of 95%.The longitudinal membrane orientation and thin channel concentration chamber, provide optimum cross flow conditions even for particle laden solutions; the centrifugal force pulling particles and solids away from the membrane to the bottom of the device. Macromolecules collect in an impermeable concentrate pocket integrally moulded below the membrane surface, thereby eliminating the risk of filtration to dryness.1.4 Pressurised OperationWhen an appropriate centrifuge is unavailable, or for single sample processing, Vivaspin® 20 can be filled with up to 15 ml and pressurised for bench top concentration.

Select the most appropriate membrane cut-off for your sample. Formaximum recovery select a MWCO at least 50% smaller than themolecular size of the species of interest.2. Fill concentrator with up to maximum volumes shown in table 1.(Ensure screw closure is fully seated.)3. Insert assembled concentrator into centrifuge (when fixed angle rotors areused, angle concentrator so that the printed window facesupwards | outwards).4. Centrifuge at speeds recommended in table 2, taking care not to exceedthe maximum g force indicated by membrane type and MWCO.5. Once the desired concentration is achieved, (see table 3a and 3b for guideto concentration times), remove assembly and recover sample from the bottom of the concentrate pocket with a pipette.8 Instructions for Use Vivaspin® 6 and 20OperationRemoving the Vivaspin® 6body from the filtrate tubeInstructions for Use Vivaspin® 6 and 20 9Operation3.4 Desalting | Buffer Exchange1. Concentrate sample to desired level.2. Empty filtrate container.3. Refill concentrator with an appropriate solvent.4. Concentrate the sample again and repeat the process until theconcentration of contaminating microsolute is sufficiently reduced.Typically, 3 wash cycles will remove 99% of initial salt content.3.5 Desalting with Vivaspin® 20Salts and contaminants can be removed in a single step when using the special diafiltration cup available with the Vivaspin® 20. This is due to the constant washing action (constant volume dialfiltration), of the buffer solution in the cup as it replaces solvent and salts passing through the ultrafiltration membrane.1. Place 2 ml sample solution in the concentrator. (Larger volumes can bedesalted by first concentrating down to 2 ml and decanting filtrate).2. Empty filtrate container.3. Insert diafiltration cup into concentrator and fill with 10 ml deionised wateror buffer solution. Re-fit blue lid over the diafiltration cup.4. Repeat concentration process; over 98% of salts will be removed in thisstep.5. Remove diafiltration cup and recover concentrated and purified sample.Operation3.6 Vivaspin® 20 Diafiltration−Diafiltration cup is filled with buffer solution(Product No: VSA005).−During concentration, solvent in sample iscontinuously replaced by fresh buffer solution.−Salts and contaminants are progressivelycleared through membrane and into filtratevessel.Technical Specifications4 Technical Specifications Table 1: Technical SpecificationsVivaspin® 6Vivaspin® 20 Concentrator capacitySwing bucket rotor 6 ml20 mlFixed angle rotor 6 ml14 mlWith pressure head–15 ml DimensionsTotal Length122 mm–116 mm125 mm with pressure headWidth17 mm30 mmActive membrane area 2.5 cm² 6.0 cm²Hold up volume ofmembrane<10 µl<20 µlDead stop volume*30 µl50 µlMaterials of constructionConcentrator body Polycarbonate PolycarbonateFiltrate vessel Polycarbonate Polycarbonate Concentrator cap Polypropylene Polypropylene Pressure head–Acetal/aluminium Membrane Polyethersulfone Polyethersulfone* D ead stop volume as designed in moulding tool.

Expect significantly longer spin times for starting solutions with over 5% solids. When operating at 4°C. flow rates are approximately 1.5 times slower than at 25°C. Viscous solutions such as 50% glycerine will take up to 5 times longer to concentrate than samples in a predominantly buffer solution.5.2 Pre-rinsingMembranes fitted to Vivaspin® concentrators contain trace amounts of Glycerine and Sodium azide. Should these interfere with analysis they can be removed by rinsing fill volume of buffer solution or deionised water through the concentrator. Decant filtrate and concentrate before processing sample solution. If you do not want to use the pre-rinsed device immediately, store it in the refrigerator with buffer or water covering the membrane surface. Please do not allow the membrane to dry out.5.3 Sanitization of Polyethersulfone Membranes Polyethersulfone membranes should not be autoclaved as high temperatures will substantially increase membrane MWCO. To sanitize, use a 70% ethanol solution or sanitizing gas mixture.5.4 Chemical CompatibilityVivaspin® concentrators are designed for use with biological fluids and aqueous solutions.

INSTRUCTION MANUAL BELL &GOSSETTV50960REVISION C H H Bell &GossettTriple Duty ®Valve With Soft SeatOPERATIONAL LIMITS Flanged Grooved Max Temperature 250°F 250°F Max Pressure 175 psig 300 psigINSTALLER:PLEASE LEAVE THIS MANUAL FOR THE OWNER’S USE.DESCRIPTIONThe Triple Duty Valve is a quiet operating heavy-duty valve which performs all of the functions normally required on the discharge side of Hydronic System Pumps.The valve serves as a nonslam check valve as needed for zoned pumping, parallel and standby pumping, and condenser water applications. The spring loaded disc prevents valve chatter, and assures shutoff.Bell &Gossett’s Triple Duty Valve has a calibrated nameplate for rough system balance. The Triple Duty Valve is also equipped with Model RV-125A Readout Valves for more accurate system balance.The calibrated nameplate with its memory button facilitates returning the valve to the balance set point after shutoff.SAFETY INSTRUCTIONThis safety alert symbol will be used in this manual and on the Triple Duty Valve safety instruction decal to draw attention to safety related instructions. When used, the safety alert symbol means ATTENTION!BECOME ALERT! YOUR SAFETY IS INVOLVED!FAILURE TO FOLLOW THE INSTRUCTIONS MAY RESULT IN A SAFETY HAZARD.*WARNING LABEL PART NUMBER V56871 INSTALLED IN THIS LOCATION.IT MUST BE REPLACED IF MISSING.2INSTALLATION INSTRUCTIONSBell &Gossett Triple Duty Valves must be installed on the discharge side of the system pump with the stem pointing up to facilitate proper seating of the valve disc. See installation drawing on page 4.NOTE:Before turning stem of 4" and larger valves, make sure the set screw in the packing nut is loose.OPERATING INSTRUCTIONS1.Place a wrench on the wrench flats on top of 3D Valve stem and open 3D Valve to the 100%open position. Stem position (amount 3D Valve is open or closed) can be read by the position of the indicator ring through the nameplate slot.2.Energize the Zone, Circuit and/or system pump(s) as applicable so that fluid is flowing through the 3D Valve. Make sure that all air has been vented from system.ing Bell &Gossett Model RP-250B readout probes, attach a Bell &Gossett differential pressure readout kit to the readout valves on the 3D Valves.4.Read the differential pressure across the 3D Valve.5.Refer to the appropriate 3D Valve performance curve or Cv rating table to determine flow based on the results from step “4” and the percent stem rise.6.If the GPM does not agree with the specified (required) GPM, close the 3D Valve accordingly. Repeat steps “4”, “5” and “6” until the required results have been achieved.7.After establishing the required balance set point, position the white rubber memory button so that the arrow, when in the three or nine o’clock posi-tion, points to the stem rise mark on the calibrated nameplate.SERVICE INSTRUCTIONSA.Valve leaking at the packing nut-turn packing nut clockwise until the leak stops.WARNING: Hot water leakage can occur from readout valves dur-ing probe insertion and during hookup of readout kit. Follow the instructions in instruction manuals supplied with readout probes and readout kits for safe use. Keep eyes protected with safety glasses. Make sure that readout valves are not leaking before removing safety cap.Failure to follow this instruction can result in serious personal injury or death and property damage.WARNING: Hot fluid leaking from valve can cause burns. Avoid con- tact with leaking fluid while servicing valve. Failure to follow this instruc-tion can result in serious personal injury or death and property damage.IMPORTANT: If system balancing at less than 50% stem rise and this is the primary balance valve, ASHRAE Standard 90.1 and Bell &Gossett recommend trimming the impeller to the necessary system design flow.This will reduce electrical energy consumption and comply with the National Energy Building Code Standard.IMPORTANT: To avoid noise problems and possible damage to 3D valve, do not exceed 25 feet of pressure drop across 3D valve.3B.If leaking persists –1.Note the position of the valve opening (%Stem Rise), if the memory button is missing.2.Turn the valve stem fully counterclockwise until the stem resists addi-tional turning.3.Remove the packing nut (located at the base of stem) by turning it counterclockwise.4.Remove old packing.5.Repack as required.6.Replace the packing nut and tighten as required.7.Reposition the valve stem per observation in Step #1.C.Valve leaking at the Bonnet gasket area – tighten (as required) until the leakage stops.D.If leaking persists, or when replacing valve internals –1.Loosen the bonnet nuts or threaded bonnet cap (depending on valve size) and remove the bonnet assembly with the valve stem attached.2.Remove the old gasket and clean up the gasket surface on the body and bonnet.3.Inspect the valve internals for signs of corrosion or erosion (wire draw across the seat). If damaged, they must be replaced to function properly.4.If the valve appears to be in serviceable condition, install a new gasket and replace bonnet assembly.5.Secure the bonnet.6.Return the system to its normal operating mode.NOTE:If leakage occurs at the bonnet gasket area, tighten (as required) until the leakage stops. Refer to 5 above.E.Replacing a damaged nameplate –1.Note the position of the valve opening (%Stem Rise).2.Loosen and remove (2) screws.3.Replace the old nameplate with one that has the same 6 digit part number as the one removed.4.Replace and tighten the screws making sure the position of the valve opening (%Stem Rise) lines up with the indicating ring near the top of the cone on the bonnet, identically as the old nameplate.WARNING: Hot system fluid can be hazardous. Isolate the Triple Duty Valve from the system with shutoff valves or drain the system.Allow isolated system and Triple Duty Valve to cool to approximately 100°F . Reduce isolated system pressure to zero. Leave drain open. Failure to follow this instruction can result in serious personal injury or death and property damage.CAUTION: Improper tightening of bonnet can cause damage to bonnet and gasket. If bonnet is bolted, tighten bolts in a crisscross pattern. Failure to follow this instruction can result in property damage and/or moderate personal injury.WARNING: Check for proper sealing when using as an isolation valve. If seat is not sealing properly, liquid will continue to flow from drain valves. In this case valve must be isolated from system pressure and inspected for seat or disc damage. Replace as necessary. Failure to follow this instruction can result in serious personal injury or death and property damage.Bell &Gossett© COPYRIGHT 1989, 2001 BY ITT INDUSTRIES, INC.DIN ISO 9001TUV CERTISO 9001 CertifiedPRINTED IN U.S.A. 12-01USABell &Gossett8200 N.

gradio then方法什么是Gradio？Gradio是一个开源的Python库，旨在为机器学习开发人员提供一个快速创建和部署自定义界面的简单方式。
使用Gradio，开发人员可以通过几个简单的步骤创建一个交互式界面，让用户可以轻松地与他们的机器学习模型进行交互。
Gradio的设计目标是让界面创建变得简单易用，并且不需要任何前端开发经验。
Gradio的核心概念是将用户界面的创建拆分为两个主要步骤：定义输入和定义输出。
在这两个步骤中，开发人员可以使用各种不同的函数和参数来自定义他们所需的界面功能。
让我们一步一步地看看如何使用Gradio 将一个机器学习模型包装成一个交互式界面。
第一步：安装Gradio首先，我们需要安装Gradio库。
可以使用以下命令在终端中安装Gradio：pip install gradio确保在安装之前已经安装了Python和pip。
第二步：导入必要的库和模型在开始创建界面之前，我们首先需要导入必要的库和模型。
假设我们有一个训练好的图像分类模型，我们想要将其包装到一个交互式界面中。
我们可以使用以下代码导入所需的库和模型：pythonimport gradio as grimport tensorflow as tf# Load the pre-trained modelmodel = tf.keras.models.load_model("my_model.h5")请注意，这里我们使用了TensorFlow库来加载我们的模型，但是Gradio 与任何机器学习库或框架都兼容。
只需使用适当的代码将模型加载到变量中即可。
第三步：定义输入和输出函数接下来，我们需要定义输入和输出函数。
输入函数定义了用户可以输入什么样的数据，而输出函数定义了模型计算出的结果如何显示给用户。
在我们的示例中，我们将接收用户上传的图像，并返回模型对图像的分类结果。
pythondef classify_image(input_image):# Preprocess the image if necessaryprocessed_image = preprocess_image(input_image)# Make predictions using the pre-trained modelpredictions = model.predict(processed_image)# Convert predictions to human-readable labelslabels = convert_predictions(predictions)return labelsdef preprocess_image(input_image):# Preprocess the input image (e.g., resize, normalize)processed_image = ...return processed_imagedef convert_predictions(predictions):# Convert the model's predictions to human-readable labelslabels = ...return labels在输入函数中，我们首先对图像进行了预处理，以便将其传递给模型进行预测。
