Filed: 1970-11-18
Abstract: 1327825 Pulse circuits AUTOELEKTRONIK AG 18 Nov 1970 [20 Nov 1969 13 Oct 1970] 54850/70 Heading H3T [Also in Divisions F1 and G1] A circuit for supplying pulses to for example a spark gap F, includes a transistor T with a feedback transformer 2, and an S.C.R. 4 which has a thermistor 8 in its ignition control circuit Z s  and which turns off T when a given collector current has been reached, so as to generate a recharging pulse for capacitors C1, C3 elsewhere in the circuit. Assuming T to be off, and a capacitor C3 charged, when contacts 3a, 3b are opened in dependence on engine rotation, a pulse is generated by an unspecified circuit SC<SP>1</SP> and applied on line 11 to turn on an S.C.R. 6 which (g and h being connected) earths one side of C3 so that the other side pulses the primary of a transformer 7 whose secondary drives the spark gap F. The pulse appears also on line 13 to energize a winding 2c on transformer 2. Winding 2b then turns on T and feedback from 2a to 2b completes the process. As T collector current increases, its base voltage rises and eventually a resistive divider R6, R8, R9 raises SCR 4 gate potential high enough to turn it on. This turns T off and feedback 2a-2b accelerates the process to produce a sufficient voltage across primary la to charge the capacitor C1 via D1, and across secondary 1b to recharge C3. In due course contacts 3a, 3b close again, and the circuit is ready to produce another firing pulse when they open. A fuel flow control device 13 may also be operated by the circuit and is connected in place of the short circuit connector h<SP>1</SP>g<SP>1</SP>; in addition the SCR 4 control circuit includes resistors 20, 21 responsive to pressure and moisture, the resistor 8 still sensing engine temperature. R8 is a thermistor. C3 is then discharged through the coil 7c to operate the fuel valve in dependence upon various engine conditions.

Abstract: 1340589 Luminescent screens MATSUSHITA ELECTRONICS CORP 16 Dec 1971 [18 Dec 1970] 58419/71 Heading H1D [Also in Division G2] In a photo-resist process of making a colour television screen wherein a film of polyvinyl alcohol-dichromate solution containing a phosphor is exposed, e.g. through a shadow mask, and the unexposed areas are washed away with warm water, the screen is then treated with a chromic acid solution to harden the exposed areas so that a subsequently deposited film containing a different phosphor will not stick to them. In the case of a three-colour screen the hardening process should be applied to the first two phosphors to be deposited. The chromic acid solution should have a pH of not more than 2 and a concentration between 0À5 and 10% by weight. Increasing concentration improves the required effect (Fig. 1, not shown) but also reduces the luminance of the phosphor (Fig. 2, not shown), so the optimum is about 5%. The screen may be of the multi-dot or of the multiline type, and may include opaque material between the phosphor areas.
