Patent GB-619902-A (GB)
Abstract: 619,902. Asymmetrically-conducting resistances. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 7, 1946, No. 29884. Convention date, Jan. 19, 1943.

Patent GB-651701-A (GB)
Abstract: 651,701. Electric totalizators. TOTALISATORS, Ltd. Dec. 15, 1948, No. 32469. Convention date, Dec. 17, 1947. [Class 106 (i)] In an electric totalizator wherein bets of more than one value, on any of two or more pools, e.g. win, place or show, may be made on any competitor at one or more ticket issuing machines, economy in the number of lines connecting the ticket machines to the counter is effected by using competitor counters C each consisting of two magnets C1, C2, both of which must be energized simultaneously to operate the counter. As shown, ticket issuing machines A, B each comprise a manually set competitor selector D, a pool selector F for "win," "place"  or "show "and three stake selectors WI, PI, Si connected to the respective contacts of the pool selector. A selection having been made, e.g. on competitor number 2 for a place bet of value 5 units, as shown on ticket machine A, the selector D is depressed, whereupon the selectors are all locked in their selected positions. When the ticket machine is connected in circuit by the usual distributer H, two parallel circuits are energized. Over the competitor selector D the left-hand winding of a trip magnet J is energized in series with all the right-hand windings C2 of the competitor counter magnets C in the second horizontal row corresponding to competitor number 2. Over the pool selector F and the operative stake selector PI the righthand side of the trip magnet J is energized in series with all the left-hand windings C1 of the column of counter magnets C in the place pool totalizer corresponding to stake value 5 units, and the corresponding grand total magnet counter GT5. The only competitor counter C having both magnets energized is that selected, i.e. that indicated at 25. This competitor counter and the associated grand total counter are therefore actuated to register the bet and the trip magnet J, which also responds only to simultaneous energization of both windings, operates to initiate a ticket issuing cycle at the end of which the selectors are released. The apparatus shown caters for four stake values on 20 competitors so that in each of the three pool totalizers U, V, W there are four counter magnets for each competitor and for the grand total which in known manner actuate individual escapements for advancing the associated totalizers. Only 32 transmission lines are, however, required. One ticket issuing machine only may be used, in which case the distributer H is unnecessary and the ticket issuing may be effected manually, the trip switch J then being dispensed with. The pool and stake selectors may be interchanged. The GT magnets may be single magnets, or as shown consist of two magnets similar to the C magnets connected in series. Alternatively, the two magnet parts of each GT counter could be connected up similarly to the C magnets except that the right-hand parts thereof would be connected to the selector arm D. The pool and stake selector switches may be spring biassed to positions most in demand.

Patent GB-2016801-A (GB)
Title: Reference voltage generating device
IPC: G11C5/14
Filed: 1979-03-06
Abstract: A reference voltage generating device comprises two insulated gate field effect transistors (IGFETs) T1, T2, whose gates are doped differently so that their Fermi energy levels are different. This causes the IGFETs to have different threshold voltages, the difference of which is proportional to the difference in Fermi energy levels. By subtracting the drain voltages V1, V2 of the two IGFETs the difference of the threshold voltages can be obtained. This creates a stable reference voltage since the Fermi energy levels do not vary greatly with temperature. A variety of methods of manufacturing the semiconductor are disclosed, depending on the nature of the IGFET to be formed. The reference voltage generating circuit is applicable to many electronic devices, such as operational amplifiers. voltage comparators. Schmitt trigger circuits battery checkers and other devices are also described. <IMAGE>

IPC: G03F1/90
Filed: 1979-10-23
Abstract: A method for tracing most of an outline in a picture, the outline being a boundary with different light values on its two sides, with a tracing head.
