Abstract: 1,218,342. Polychromatic matrix displays. SEEMARK SWITCHES Ltd., P. D. R. ADAMS, and C. A. T. HUNTLEY, [trading as ADAMS HUNTLEY ASSOCIATES]. 9 Aug., 1967 [9 May, 1966; 8 July, 1966; 31 Aug., 1966], Nos. 20478/66, 30809/66 and 38923/66. Heading G5C. The display screen is formed by an array of elementary screens 12, Fig. 3, each one being illuminable in a range of colours by a bank of relay-controlled lamps 21 or by transducers, e.g. colour filters 65, Fig. 10. The device is controlled by a matrix of control components (e.g. photo-cells or magnetic memory cores). As described, see Fig. 3, colours are obtained by having four lamps 21 each with a different colour filter, e.g. 17, 20 and each adapted to project uniformly on to the whole screen, centering on 23. The lamps are lighted separately or in chosen combinations. In Fig. 10, however, there is only one lamp 58 per screen 62 and colours are selected by moving filters 65 into the light beam by electromagnetic servomechanisms 64. A shutter 63 can obturate the beam. Two control methods are described. In one, light from a cine or slide projector impinges on a matrix of photo-cells, each of which can activate a corresponding relay. Each frame of the slide or film may be divided into four quarters, each corresponding to a colour; or the film images may consist of a pattern of spots, and where the arrangement of Fig. 10 is used, shutter 63 is controlled by a " detail " spot appearing a few frames in advance of the other " colour control " spots. In the second method, coded information is stored on magnetic tape and fed when desired to a core matrix. In either method the number of lines leading to each lighting unit can be reduced by the use of coded pulses. A relay stated to be suitable for the device is described in Specification 1,218,343. It is stated that the filters 65, Fig. 10, may be air-jet driven; this assists in cooling.

Title: Electrical generating system for an automotive vehicle
IPC: H02J7/16
Filed: 1971-08-23
Abstract: 1321326 Automatic voltage control FORD MOTOR CO Ltd 23 Aug 1971 [29 Oct 1970] 39388/71 Heading G3R A vehicle generating system includes a voltage regulator which is switched into an operative state in response to the lowering of the terminal voltage of the vehicle battery during operation of the starter motor. In the embodiment shown, an alternator 10 is connected through a rectifier 18 to a battery 28, switching circuit 66, and voltage regulator 70. The regulator includes a transistor 95, in series with the alternator field winding 60. In normal conditions, with the vehicle inoperative, the battery voltage across potentiometer 100 is sufficient to hold transistor 104 of a Schmitt trigger circuit in a conductive state, rendering transistors 106, 122 non-conductive. Thus, a thyristor 128 is blocked and no base current can flow to a transistor 138. The base of regulating transistor 95 is not energized and no current can flow in the field winding 60. When a switch 32 is moved to energize starter motor 46, the battery terminal voltage drops sharply, and is no longer sufficient to turn on transistor 104. Transistors 106, 122 now conduct, triggering thyristor 128 and allowing transistor 138 to conduct and energize the regulator circuit 70. Transistor 95 now conducts to allow current to flow in winding 60, and the alternator output voltage is regulated by Zener diode 86, which cuts off transistors 88, 95, if the voltage exceeds a predetermined level. The operation of the alternator raises the voltage at neutral point 150 so that a transistor 162 turns on and provides a path for base current of transistor 138 even when the rise in battery terminal voltage causes thyristor 128 to block. A further embodiment, Fig 3 (not shown), uses an integrated circuit regulator (not detailed), and the thyristor 128 is replaced by a monostable circuit which introduces a time delay after which the switching circuit is returned to its initial state if operation of the alternator has not begun.
