Patent GB-783108-A (GB)
IPC: G11C11/42
Abstract: 783,108. Statistical apparatus; electric digital data-storage apparatus; comparing digital data. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 1, 1955 [Feb. 4, 1954], No. 2927/55. Class 106 (1). A comparing device, e.g. for a record card collator, comprises means for generating a first pulse train representing first information, means for generating a second pulse train representing second information and means for simultaneously receiving and comparing said pulse trains and for indicating the result of the comparison. As described the apparatus compares the numeric or alphabetical data on successive pairs of primary and secondary cards 101P, 101S, Fig. 2. Each card comprises three decks A, B, C each having sixty columns of seven index positions designated " 5 ", " 3 ", " 1 ", " 0 ", " Z ", " Y '', " X " at which holes may be punched to represent information. The primary and secondary cards pass between read, brushes 91P-95P, 91S-95S and contact rolls 110P, 110S respectively. Each brush is connected to a corresponding arm 61PA-65PA, 61SA- 65SA of commutators 61P-65P, 61S-65S each having seven conducting segments which are connected, as shown, to write heads PW1- PW5, SW1-SW5 uniformly disposed about the periphery of primary and secondary magnetic recording drums D1 and D2. The information on the record cards is transferred to the drums D1, D2, each brush 91P-95P, 91S-95S transmitting the data it senses in the associated column via the corresponding writing head PW1-PW5, SW1-SW5 to the drums D1, D2 index position by index position so that in one fifth of a revolution of the drums the information in the five columns being sensed is written upon the primary and secondary tracks of the drums. Within the drums D1, D2 are read heads RP1, RS1 which rotate on the drum axis to transmit the stored information in serial form column by column to inputs 1C, 3C, Fig. 3 (not shown), respectively of a comparer circuit which indicates by energization of one or other of two relays which of the two series of pulses represents information of the higher " order ". Neither relay is energized if the two series of impulses are of equal " order ". The comparer can also distinguish between a series of pulses representing alphabetic information and a series of pulses representing numeric information. The arrangement is such that the result of the comparison is indicated as soon as possible. The primary and secondary read heads then effect erasure of the information from the primary and secondary tracks. Specifications 523,652, 550,843, 614,016, 668,843 and 754,387 are referred to.

Title: Circuits for electric window winders for vehicles
IPC: E05F15/16
Filed: 1978-10-09
Abstract: An electronic control circuit for an electric window winder for a motor car, which allows the window to be moved to a fully open or fully closed position simply by a momentary operation of a push-button. A latch within logic circuit 30 is associated with each push-button 32, 34, and is set by operation of the push-button, to keep the motor 10 energised. If the motor current falls to normal fairly quickly, this shows that the window is moving; any subsequent abnormal rise in current indicates that the window has met an obstruction, or reached the end of its travel, and the latch is then reset, turning the motor off. If the motor current remains abnormally high after starting, the direction of energisation is reversed, to ascertain whether the window is stuck, or at the end of its travel. If the former, the motor is reversed at intervals to free the window; after nine unsuccessful reversals, the latch is reset. If the latter, the motor returns to its original direction, and returns the window to the end of its travel. <IMAGE>

Title: Treatment of tobacco
IPC: A24B15/24
Filed: 1978-10-20
Abstract: Tobacco which contains relatively high quantities of desirable flavorants, for example, a flavorful bright tobacco, is contacted in a temperature of 140 to 180 DEG C, and preferably 160 to 170 DEG C, with a stream of nonreactive gas for a time sufficient to result in a weight loss (in excess of oven volatiles) of 3 to 10%, and the volatile constituents of the resulting gaseous stream are condensed, for example, by passing the gaseous stream in contact with a surface at a temperature of - 78 DEG C or lower to 30 DEG C. The condensate may be used subsequently to flavor a smoking material, for example a tobacco-based filler material which is flavor deficient but has relatively low quantities of tar- and nicotine-producing materials, in order to enhance the organoleptic properties of its smoke. Alternatively, the flavor content of a tobacco, for example, an Oriental tobacco, may be reduced from a undesirably high level to a more desirable level, without otherwise deleteriously affecting the tobacco. <IMAGE>

Patent GB-2057718-A (GB)
Title: Servo system
IPC: F15B18/00
Filed: 1980-07-30
Abstract: A servo system has an output servo motor 4 (104) controllable through one or other of two identical servo control circuits 16A, 16B (116A, 116B) each of which includes its own source of pressure fluid (PA, PB) and a servo control valve 20A, 20B (120A, 120B) for the motor to thereby provide duplicity. Selection of one of the control circuits is made by a two-position switching valve 22 (122). The control valves are coupled together to receive one or more control inputs, the valve in the non-selected circuit following the position of that in the selected circuit. The switching valve is responsive to the pressures of the respective sources by way of two pistons of differential areas 56; 62 (156; 162) so that normally the switching valve is biased to select a particular control circuit but can switch automatically to select the other control circuit. A safety valve 80 (200) is operable by a failure, e.g. jamming of the servo control valve in the normally selected circuit, to release the pressure on the piston associated with that circuit so that again the switching valve switches automatically to select the other control circuit. Upon switching the switching valve cannot revert to its initial position. <IMAGE>
