Hand operated on base. The generator is self exiting and charge separation occurs. A metal sphere surrounds the upper pulley assembly and charge accumulates on the sphere, which is insulated by a plastic column supporting the pulley assembly. The charge builds up untill electrical breakdown of air surrounding the sphere occurs. Supplied with a discharging sphere.

Oil Free Vacuum Pump, Exclusive oil-less construction of piston or diaphragm does not requires lubrication, practically maintenance free, portable light weight die-cast aluminium components. Balanced eccentrics provide smooth, low vibration operation. Built in micro air filter, fitted with metal round plate.

A model of two-stroke diesel engine made in aluminium alloy and gun metal. Ignition is shown by means of a miniature bulb. Fuel supply is also sectioned. With hand crank, provided for manual operation. Mounted on base.    

For use as a water turbine to drive a generator producing electricity or for use as a pump driven by a motor and raising a head of water to produce potential energy. The rotor has eight 'bucket' blades and is housed in a block turbine chamber with a clear Perspex front. Two inlet tubules (for turbine and pump operation respectively) and one outlet tubule are provided, and the shaft carries a 15 mm. diameter pulley. With driving belt.    

For studying the characteristics of a TRIODE VALVE and its practical applications.    

  are designed to meet the requirements of Research, Colleges, Schools and Industrial laboratories. They are used for accurate measurement of the diameters of different objects. They are also used in Physics Laboratories for more accurate determination of small variation in the liquid levels, Manometers, the refractive index of liquids as well as in surface tension & viscosity experiments. The travelling microscope consists of a cast iron base with machined vee-top surface and is fitted with three levelling screws, one being fixed the microscopes can travel Horizontally 22 cm. and vertically 15 cms. with the help of slides.
