|WORCESTER CIRCUIT BOARD|
|Code:GP - 759.1|
Consists of a base board, complete with terminals, a set of metal connection pillars and a number of clips on flexible connection strips and accessory units, enabling a wide variety of electrical circuits to be constructed quickly and easily. The phosphor-bronze strips are so designed that when flexed a little in the fingers, they are easily slipped over the pass where their natural spring holds them firmly in position and ensures a good electrical contact.
The following components are supplied with each board. 20 Flash lamp bulbs, 1.25V, 0.25A, 9 Connectors with lamp holder, 12 Plain connectors. 1 Connector with rheostat, 1 Rectifier, 1 Resistor, 2 Flexible leads with 4mm plug and crocodile clip, 2 Flexible leads with crocodile clips, 2 Crocodile clips, 2 Mounted bell pushes, 2 Soft iron nails, 50mm Square head, 1 Length bare copper wire 20 swg, 1 Length bare Eureka wire 34 swg, 1 Length plastic covered copper wire 26 swg, 1 Plastic disc, drilled, 1 Pencil leads, 1 Piece copper foil, 1 piece steel wool. The standard pack is one complete set as detailed above, sufficient for two students.
|MORSE KEY AND MORSE SOUNDER|
|Code:GP - 764.3|
| Mounted on wood base Morse key has adjustable pivots, variable spring tensions and variable movement & an open construction with twin coils. Adjustment provided on the armature, spring tension and movement.
|DEMONSTRATION ELECTRIC MOTOR|
|Code: GP - 766.1|
| A model of the simplest form of a d.c. electric motor, having three armature, 2 pole, 3 pole and 4 pole, wound with enamelled copper wire, and a permanent provided by removable bar magnet. The construction of the model is completely open and all components are readily observable. A disc type commutator is incorporated and external connection to the phosphor bronze bushes is by means of a pair of 4mm sockets. The motor will operate on 4.5 to 9V D.C.|
|Code: GP - 775.1|
| This model uses the same basic assembly as the motor Cat. No. 766.1 But is mounted on a base plate 225x100mm which also carries a hand-driven pulley 120mm diameter coupled to the smaller dynamo pulley by s rubber belt. Electric output is via a pair of 4mm sockets, and light emitting diode is provided as simple output indicator. The model may also be used as motor on a 4 to 8v D.C. Supply.|
Overall height : 150mm.
