A centrifugal pump is mounted integrally in the framework and is connected to the filter inlet via a throttle valve and pressure gauge.
A fully self-contained plate and frame type filter press constructed entirely in stainless steel.
Filter surface area is 0.22m² and solids holding capacity is 1.5 litres.
A back pressure valve is located at the filter outlet.
The filter pack is made up of four plates and four frames, which will accept a dressing of seven filter sheets 200mm x 200mm.
The filter pack and sheets are compressed manually using a hardened steel screw thread.
The Compression Ratio can be changed without stopping the engine and without altering the combustion chamber geometry by means of a specially designed tilting cylinder block arrangement both during gasoline running and during Diesel running. Computerized Variable Compression Ratio Multifuel Engine Test Bed allows to perform experiments concerning this kind of engines. The unit consists of single cylinder, four stroke, Variable Compression Ratio (VCR) engine connected to eddy current type dynamometer for loading. Setup is provided with necessary instruments for combustion pressure and crank-angle measurements. The test bed includes a stand-alone panel box consisting of air box, two fuel tanks for duel fuel test, manometer, and fuel Measuring unit, transmitters for air and fuel flow measurements, process indicator and engine indicator. Rota meters are provided for cooling water and calorimeter water flow measurement. These signals are interfaced to computer through engine indicator for pv diagrams. Provision is also made to interface airflow, fuel flow, temperatures and load measurement.

The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce combined drives and their correct assembly. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas. All the system components are kept ready to hand and well protected in a housing system. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing.

The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components are arranged. The loss is measured by differential pressure using manometers. Pressure tapping is by valves with quick connection. Piping Loss Test Set Small is a self contained unit for studying the friction loss in pipes, pipe fittings and valves at various flow rates. The unit is on a steel frame on wheels. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses.
Experiments:
Friction losses in pipe fittings, valves, sudden expansion and contraction at various flow rates.
Friction losses in straight pipes at various flow rates.
The is available in two basic configurations. The standard is the simplest system. As standard the filtration assembly works with polymer membrane filters (90mm diameter) and sample filters are included for microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). A backpressure valve is used to adjust the transmembrane pressure with a maximum allowable system pressure of 40 bar (analogue pressure indicator). A wider range of filters are available on request. It uses a high pressure stainless steel piston pump to circulate product from a food vessel to the filtration assembly with simple on/off control.
The 50 is an enhanced unit, with all the additional benefits of computer control, data logging and diafiltration capability. There is also an electronic mass balance to measure the mass of permeate collected. This option also enables diafiltration using a peristaltic pump and high level sensor. It includes an electronic pressure sensor to measure filtration pressure (0-40 bar) and electronic temperature sensor (thermocouple) to measure retentate temperature. It also includes a feed pump speed controller, which enables the retentate cross flow velocity over the filtration membrane to be varied. The data from all these is logged in the software enabling plotting of permeate flow rate with time so that the effect of variables (filtration pressure, cross flow velocity, product temperature and diafiltration) on process performance can be determined. The software can be used to define the mass of permeate collected prior to addition of water/buffer (batch diafiltration). Communication to the PC (not supplied) is via an internal USB interface.
Features:
Suitable for microfiltration, ultrafiltration, nanofiltration and reverse osmosis membranes and pressures. Pressure operating range of 1-40 bar.
Uses a standard filtration size of 90mm enabling a wide range of filtration membranes to be used
Optional ceramic membrane available
Supplied with a range of polymer membranes.

The gear box is mounted on a assembly stand and can beturned around its own axis.
The kit contains all the parts required to assemble a functional lever shears. The graphic symbolises standard and production parts, and represents fixed and moving connections differently. All parts are precision-manufactured on CNC machines and feature standard engineering tolerances and surface finishes. The parts are clearly laid out on a base plate. They are grouped into individual assembly sequences. The base plate is covered with a transparent cover panel on which a graphical representation of the assembly structure is printed. Multiple trays are stackable, providing for space-saving storage. The surfaces of the finished parts have a gunmetal finish to prevent corrosion.

The detector signal can be analyzed via two separate communication channels, termed motion detector and presence detector. Another main application is the automatic control of the lighting on an office workplace. Presence Detector And Brightness Sensor is a presence/motion detector with integrated constant light level control. It contains an independent light sensor with integrated 2Â level light control (switching) and constant light level control (dimming). Presence Detector And Brightness Sensor communicates via actuators or other devices.

An electrically powered device designed to deliver high-flow (exceeding peak inspiratory flow) heated and humidified ambient air or air/oxygen to a neonatal patient as part of non-invasive ventilation (NIV); it may additionally be used with a water tank to produce bubble continuous positive airway pressure (bubble CPAP). It is intended for use by a healthcare provider on a spontaneously breathing patient in hospital settings. It consists of a gas flow generator that entrains room air, an oxygen concentrator, a heating provision, and humidification chamber; it does not include CPAP controlling pressure sensors.
