The unit consists of a metal base plate with a fixed axle and a rail made of steel. Two further axles can be clamped to the rail in any position. This benchtop unit conveys the relationship between the number of gear teeth on spur gears and the transmission ratio of gear trains. In this way it is is possible to construct one and two stage gear trains with any combination of gears. Drive pins couple the gears. Four plastic gears are included with the unit. A plastic box is used to store the parts not in use. By undoing a locking pin, the rail can be swivelled around the fixed axis providing a demonstration of planet gear trains.

The air flow can be varied by regulating the butterfly valve situated at the blower outlet, and the flow rate calculated from the pressure drop across the blower inlet orifice as measured by the sloping manometer mounted against the back of the bench. The essential component of the apparatus is a large, stainless steel duct which is supplied with air from a small blower via a set of damping filters. A window is provided in the air duct to enable the various readings to be taken without disturbing the conditions inside. A further wet and dry bulb hygrometer of the aspirated type is provided in which the inclusion of an integral blower affords constant air velocity across the bulb. Instrumentation consists of two screen-type wet and dry bulb hygrometers, one giving a digital readout by means of thermistor probes and the other giving a direct readout via a glass thermometer. Finally, there are two further types of hygrometers included with the apparatus, the first being a hair hygrometer seen through the window and the second one being a Vaisala capacitance type instrument with digital readout shown on top of the bench. A sling hygrometer is included, to demonstrate a further, simple method of ventilation of the wet and dry bulb type.

The unit includes a metal bar with additional sliding weights as a rigid pendulum. The suspension point can be adjusted at the knife edge bearing of the pendulum. The length of the thread pendulum included can be easily varied using a clamping device. The model is used to investigate the oscillation of pendulums. During this process a physical pendulum is compared with a mathematical pendulum. The model is suitable for student experiments. The components of the experiment are attached to a base plate intended for wall mounting.

The unit itself includes the electric drive motor with speed control, 2 pressure vessels for the compressor experiments, a measuring tank and a supply tank for the pump experiments and a protection cover. The intake and delivery pressure, temperature, motor speed and power are measured and displayed digitally. The modular system allows the investigation of different machines (reciprocating machines and turbo machines). The corresponding flow is measured indirectly and transferred to the PC data acquisition software. Each machine is mounted on a base plate, which can easily be fitted into the unit. It is powered by a belt drive. Hoses with quick-action couplings provide the supply lines.

Pressure variations are made by the rotary vane pump which is provided with needle valves at entry and discharge. A further valve is incorporated at the pump outlet with pressure tappings either side of it to enable differential pressure measurements to be made and plugs are supplied to blank off any connections not in use. The apparatus consists of a series of pressure/vacuum measuring instruments mounted on a wheeled bench with an electrically driven rotary vane pump to provide the necessary pressure and vacuum. The bench also includes a microprocessor based portable digital pressure calibrator for pressures between -1 and 10 bar. The measuring instruments include a sloping, liquid filled manometer reading pressure from 0 to 75mm of water, a vertical manometer reading from 0 to 200 mm of water, a manometer reading from 0 to 760 mm, a pressure transducer with analogue readout and a Bourdon tube gauge scaled - 1 to 2.5 bar for reading both pressure and vacuum.
