Title: Photoconductive unit with ternary glass semiconductor - contg selenium and tellurium, for light detecting devices
IPC: H01L31/08
Filed: 1973-09-13
Abstract: A photoresistant unit for detecting light comprises an active zone made of ternary semiconductive amorphous glass layer sandwiched between metal electrodes one of which covers entirely one of the surfaces of the glass layer and the other covers virtually the whole of the other surface and rests on an inert substrate. A source of light is so placed that photons emitted there from are directed towards one of the two surfaces of the glass layer. Either the first electrode is semi-transparent and faces the source of light while the other electrode and the substrate are both opaque or the first electrode is opaque while the other electrode is semi-transparent and the substrate is transparent and faces the source of light. In uses the electrodes are electrically connected and voltage applied. The unit is used as a photo-cell and in optoelectronic devices. It exhibits a high photoconductivity gain (>1) and use of the glass layer obviates the need for thermal treatment during or after depositing the glass on the substrate. Other advantages are: homogeneity and reproducibility of the active zone, sensitivity to spectrum emitted by tungsten filament, response time 2 milliseconds and stability to temps. up to 100 degrees C.

Title: Ballast inductor for gas discharge lamps - has entirely separate two-part insulating housings for each winding head in one piece with head insulator
IPC: H01F5/04
Filed: 1973-11-29
Abstract: The ballast transformer or choke for gas discharge lamps has a T-shaped laminated core enclosed by a U-shaped laminated jacket. The insulated winding is located on the core and its heads or ends have their own insulating hourings (10, 11) on the outside of the laminated jacket. The insulating housings are each constructed from a first part which insulates the winding end from the core and a second part which covers the winding end on the outside. The two inner parts extend down farther than the two outer parts to form latches or pegs which locate in a support rail (6) at the base of the transformer or choke. This configuration reduces the number of insulating components and speeds up mass production.

Title: Electronically operated game of chance - has tubes illuminated successively to give moving light spot illusion with random stopping
IPC: A63F9/04
Filed: 1977-05-05
Abstract: The game of chance is operated by means of tubes which are illuminated successively to give the illusion of a moving spot of light. The tubes are electronically operated, each having a suitable motif or number. Pressing a pushbutton charges a capacitor through a resistance for a variable time; releasing the button discharges the capacitor through a second resistance. An oscillator frequency is proportional to the voltage and this energises a counter which lights the tubes. The speed of the light spot appears to increase rapidly to a maximum and then decreases to stop on any position at random.
