Rugby Latent Heat of Steam Apparatus   (HT-1577)

It comprises of a thick brass calorimeter 90 x 65 mm (Length x dia), a bung with steam inlet and outlet tubes, a felt cover and 1000 c.c steam boiler with bung to connect steam tube to calorimeter.

Accessories & Spares

Calorimeters, Rugby pattern, (a) Brass 1.1 Kg (b) Iron 0.8 Kg, (c) Al 0.35 Kg, (d) copper 0.9 Kg

Hero's Engine   (HT-1578)

This is an earliest form of steam turbine. It consists of a borosilicate glass bulb 70 mm (Approx.) with side arms bent at right angle and formed into jets at their tips. The bulb is mounted on a metal stand so that it can rotate freely with the help of supporting arms when the bulb filled with water is boiled. The issuing steam produces high speed of rotation. Supplied without burner. The overall size is 180 mm x 120 mm (Approx.)

ENGINE MODELS

The objectives of presenting undermention models is to make students understand theory and working principles of various engines i.e. steam. Petrol, Diesel & Gas etc. These models are not functional in the true sense.

Steam Engine (Fuel Operated)   (HT-1579)

This is a demonstration model with oscillating cylinder, safety valve and whistle and throttle valve, fuel heated. The mode mounted on a metal base.

Steam Engine (Electrical)   (HT-1580)

Same as but works on 230V, 50HZ single phase

Steam Engine with Dynamo   (HT-1581)

It consists of a powerful fixed cylinder engine with a slide valve driven from a crankshaft eccentric. The engine is provided with a double take-off pulley and is mounted on a metal base.

Steam Engine Sectional Model   (HT-1582)

The engine model comprises a section cut metal cylinder covered with transparent acrylic plate to observe the working parts -piston, valves, link motion and reversing methods. The movement of wheel is very light to demonstrate the working even by blowing through mouth. Mounted on a moulded metal base.

Two-Stroke Petrol Engine Model   (HT-1583)

This is a sectional working model of 2-stroke petrol engine. All the parts are made of metal or Al-alloy nicely painted. The ignition is shown by means of miniature bulb. The sectional view of carburetor and fuel supply is nicely presented. A crank handle is provided for manual operation. The complete sectional working model is mounted on a well polished wooden base with printed diagram for demonstration.

Four-Stroke Petrol Engine Model   (HT-1584)

The model is same as above but the sectional detail of the 4-stroke petrol engine is nicely demonstrated.

Two-Stroke Diesel Engine Model   (HT-1585)

In this sectional view of two-stroke diesel engine is demonstrated. Made of AI-ferrous metal alloy. The engine is shown in half section as above models. The working parts moves in correct path in relationship to another when hand crank is rotated.

Four Stroke Diesel Engine Model   (HT-1586)

As above but demonstration of sectional view of working components/parts of 4-stroke diesel engine.
ENERGY CONVERSION KIT
This kit comprises a number of units to show qualitatively energy conversion from one form of energy to another.

Large Motor/ Generator Unit   (HT-1587)

It comprises as 4-6 V D.C. motor provided with a 15 mm diameter V pulley, supplied complete with driving belt. Mounted on base with 4mm socket terminals.

Small Motor/Generator Unit   (HT-1588)

As but 1.5 to 4.5 V motor supplied complete with driving belt.

Switch Unit   (HT-1589)

A double-pole, double-throw knife switch for connecting motor/generator to either the power supply or the lamp unit. The socket terminals are marked for battery, motor and lamp.

Lamp Unit Triple   (HT-1590)

It consists of three bulb holders connected in parallel with two 4mm sockets, mounted on a standard base. Complete with bulbs.

Flywheel Unit   (HT-1591)

Iron flywheel 115 mm diameter mass 1.25 Kg, mounted on stand post with nylon or metal bearings. The shaft has an aluminium V pulley for driving with spring belt. It is to be used to demonstrate the conversion of electrical energy to kinetic energy & then back.
