Title: Encoders for electrical signals
Inventor: GABRIEL MALCOLM EDWARD
IPC: H03M1/06
Filed: 1966-11-22
Abstract: 1,113,700. Analogue-to-digital converters. STANDARD TELEPHONES & CABLES Ltd. 22 Nov. 1966, No. 52125/66. Heading G4H. In an encoder for converting analogue signals into a symmetrical binary code, the zero level of the input signal is adjusted to lie in the centre of the code range by a feed-back between the digit output and the input, having means for examining the polarity of each of the successive channel codes, means assigning a polarity to a block of channel codes, means for generating a corresponding analogue bias signal which is applied to the input to equalize the number of channels having opposite polarities. The digital outputs are each preceded by a polarity signal which are gated by gate 10 to a counter 9 the output of which indicates whether the majority in a group of channel codes is positive or negative. Flip-flop 6 is set in one state or the other and integrator RC to a bias signal generator 8 to apply a signal to the input at 3. The whole block of channels may be divided into m groups of n channel codes, each n channel codes being examined as before to see whether the majority is positive or negative and the outputs are applied to a further counter indicating whether the majority of the n groups has a positive or negative preponderance. The counter adapted to indicate whether the majority of n polarity signals is positive or negative has a capacity of ¢ (n + 1), n being odd. The capacity will be exceeded or not to give the required indication.

Title: Improvements in pumps

Abstract: 1,105,709. Fluid-pressure servomotor systems. SPERRY RAND CORPORATION. Dec. 31, 1965 [Dec. 31, 1964], No. 55343/65. Heading G3P. [Also in Division F2] A variable displacement pump, having a swashplate biased to the maximum stroke position and moved to decrease displacement by a servopiston when a predetermined pump outlet pressure opens a control valve, is also provided with a bypass valve that allows the outlet pressure to act on the servopiston during starting, thereby obviating high starting torques, the by-pass valve being closed when the outlet pressure reaches a value considerably lower than said predetermined pressure. As shown, during starting the pump outlet passage 72 is connected by lines 82, 84, bore 132 housing by-pass valve 134, and bore 91 to the interior of a sleeve 76 over which a piston (74) Fig. 1 (not shown) is slidable. Piston (74) is thereby moved to reduce pump displacement. When the outlet pressure reaches a first value, it acts on the end 150 of valve 134 via passages 146, 148 in the latter to move it upwards to cause land 136 to block bore 132 and land 140 to open vent passage 124'. The outlet pressure then rises further until it moves control valve 106 upwardly, such movement allowing fluid to flow to sleeve 76 via bores 104, 90" and 98 to reduce the pumps displacement. The pump 10 may be used as in Fig. 2 (not shown) to control a fluid motor 26 via a valve 20, a relief valve 38 being provided in the pump outlet line 16.

Abstract: 1,186,707. Washing machines. DANFOSS A/S. 6 Dec., 1967 [17 Dec., 1966], No. 55322/ 67. Heading D1A. In a washing machine, a drum revolution counter serves as timing means to control timed functions of the machine. The drum 2 is driven by electric motor 4 through belt 3 when a command is transmitted from control unit 5 over line 6 and every time that a magnetic element 13 on the drum passes pick up 13' on the housing, i.e. once a revolution during washing, it generates a pulse which is fed to the counter 11. Other command lines 7 lead from unit 5 to electromagnets for the water supply, the washing agent supply, evacuating pump, heater and the like and information is fed to unit 5 by leads 8 from thermostats, level gauges and the like and by leads 9, 10 from timer/counter unit 11. The programme is selected by a plate 1-2 inserted in unit 5. Counter 11 comprises eight binary stages 14 and a first output 15 which transmits a signal when 75 is reached and a second output 16 which transmits a signal when 255 is reached, the latter passing through lead 9 to unit 5 to cause a change-over to the next section of the programme. In another arrangement the counter 18 is incorporated in, unit 5 and comprises twelve binary stages 19 and a decadic coder 20 with several outputs E at which a voltage appears in succession when a pulse is fed to the input. The washing machine comprises seven operating circuits A1-A7, five control circuits S1-S5 and one timer circuit 21 corresponding to the normal operations and controls, run-dry and overflow circuits being included if required. On sensing the completion of a programme section, each control circuit transmits a pulse to input 21. An interchangeable key plate and a fixed switch box 24 are provided between outputs E of counter 18 and the inputs of circuits A, S and Z. The spin drying may be similarly controlled even if it takes place in a separate drum.
