Title: Light reflector unit with secondary source - has elliptical reflector surface centred on light source
IPC: F21V7/00
Filed: 1974-12-06
Abstract: The unit consists of a reflecting surface and a source of light forming a cluster of beams with a predetermined angle of divergence. The reflecting surface is generated by a curve forming an elliptical arc (E1) whose centre (F1) coincides with the light source (S), while a second centre (F2) acts as a source of secondary emission. The length (e10-e11) of the elliptical arc defines the direct angle of emission (beta) of the light from the source (S) and that (gamma) from the secondary source (F2). The rear part (e11) of the elliptical arc extends as far as a point corresponding to the end vector ray (R11) emitted from source (S). This ray, after reflection, does not pass back through the casing (S1) of the source (S).

Title: Fluorescent lamp socket with length compensation - has support terminal pins attached to carrier movable WRT socket body
IPC: H01R33/08
Filed: 1975-07-24

The socket is circular and is provided with a location slot within its outer shell. Leaf spring electrical contacts are arranged symmetrically about the socket centre leading to power connection lugs at the socket base which are trapped in a support plate. Variations in length are taken up by a contact support structure moving lengthways with respect to the shell of the socket. Some degree of 'rocking' is allowed for in the design while the tube is maintained centrally.

Abstract: The writing teaching aid is used for practising correct formation of letters etc. It comprises a plate carrying an insulating trace of the letter, surrounded by a conductive layer. A frame enclosing a translucent flexible sheet is positioned over the plate and the student traces the letter via a stylus. The underneath surface of the translucent sheet has a conductive coating, so that when the stylus deviates from the trace, this conductive coating contacts the conductive layer to close a circuit for energising an alarm bell. The trace is invisible through the translucent sheet except for several guide markings and its size is dependent on the ability of the student.

Title: Bistable static power switching circuit - has full wave diode rectifier with Zener diode and thyristor circuit to suppress parasitic transients
IPC: H02M5/257
Filed: 1976-03-10
Abstract: Static power switching for circuits supplied from an a.c. source. The thyristor based bistable switching is achieved with a minimum of parasitic transients without the use of separate attenuating filters etc. or conduction maintainance circuits. The circuit is based on the use of a classic full-wave diode bridge with a parallel Zener diode across which the main thyristor and a series dropping resistor are connected. Continuing thyristor conduction is achieved by a CR chain across the gate. The charge on the capacitor is maintained by a further thyristor whose gate is controlled from a diode-unijunction transistor circuit.
