Demonstration Gear Model System
Description
A series of models to demonstrate different gearing systems. With transparent slideplates, the gears may easily be seen and where necessary there is an index on the primary and secondary shafts to show the change in the direction of rotation and the relative speed of rotation. A simple three-speed and reverse-gear system using spur gears. Reverse gear is obtained by interposing a small lay-shaft mounted pinion between the two main shafts. Gear selection is by means of a short ball-ended lever.
Analog PID Controller
The analog PID controller is a special purpose analog controller with operational amplifiers The controller permits a detailed analysis of the application of proportional, integral and derivative control to the improvement of their performance. The controller may be used at high speed for oscilloscope observation or at a low speed for meter observation.
FEATURES:
• Two analog meters (centre zero meters) to display the set variable and process variable. • In built regulated power supply. • Provision to vary and measure the setpoint (0-5)V • Provision to vary the proportional gain, Integral time and derivative gain. • Provision to give either (4-20)mA or (0-5)V externally as a process variable. • Provision to select the controller output as (4-20)mA or (0-5)V internally. • All the components are mounted in an attractive cabinet. • Interface with any realtime process (Level, Flow, Temperature, Pressure, DC motor speed control etc.,)

Newton’s Color Disc
Description
To demonstrate the discovery made by Newton that white light is composed of seven colors. Consisting of a pulley mounted on a metal stand, the seven colored disc is driven by gears connected to a hand driven wheel. When the colored disc rotates, the eye can’t distinguish between individual colors and perceive it as white color.

Desert Cooler Trainer
Desert Cooler Trainer works on the principle of evaporative cooling. It is used mostly in the dry hot regions; it consists of a fan which sucks the air from atmosphere through the pads which are used in desert coolers very frequently. The difference in DBT & WBT at inlet and outlet can be measured hence the RH from the charts. Also the amount of water evaporated can be calculated by knowing the water level difference in the reservoir.
SPECIFICATIONS:
1.Fan connected to 1/2 HP motor. 2.Air Cooler Pump to circulate water. 3.DBT & WBT Measuring Thermometer at inlet and outlet. 4.Orifice meter with manometer to measure the air flow. A technical manual accompanies the unit.SERVICES REQUIRED:
1.Floor Area – 1, X 1 m. X 1 -5m. Height. 2.220 V., 15 Amp. , Single Phase Stabilized power supply

Emissivity Measurement Apparatus
The apparatus consists of a test plate and a comparator. A black plate is used as a comparator for test plate. When all the physical, dimensions and the temperatures are equal, heat losses from both plates will also be the same, except radiation losses. Hence the input difference will be due to difference in emissive. Both the plates are kept in a panel enclose with perplex front and are given inputs through separate dimmerstats so that temperatures of both can be kept equal. Thus emissivity can determine over a wide range of temperatures.
SPECIFICATIONS:
1.Test plate and Black plates — 160mm. Dia. Aluminum plates, mounted in Panel with mica heater inside. 2.Instrumental panel consisting of- a)Voltmeter and ammeter for input measurement to both heaters through a selector switch. b)Separate dimmers for both the plates. c)Multichannel digital temperature indicator. A technical manual accompanies the unit.SERVICES REQUIRED:
1.Space area of 1.5m x 1 m. at working height. 2.230v, 15A, AC supply with earthing connection
Electric Motor St. Louis
Description
The motor consists of a two pole armature mounted between the ends of two bar magnets. The armature has a two section commutator and a pair of slip-rings on its shaft and is so constructed that the wire cannot slip off the iron core. The upper bearing and brushes for the commutator are mounted on a strong upright. Separate brushes are provided for the commutator and for slip rings and each are connected to a terminal. The magnets are held in position by thumb screws.
