Patent GB-364217-A (GB)
Title: Improvements in automatic control devices for talking machines
IPC: G11B17/02
Filed: 1930-10-20
Abstract: 364,217. Gramophones. GRAMOPHONE CO., Ltd., Hayes, Middlesex, THOMPSETT, H. A., 26, Castlebar Park, Ealing, London, and CHIFFEY, E., 48, Corbins Lane, South Harrow, Middlesex. Oct. 20, 1930, No. 31472. [Class 40 (ii).] A device for automatically stopping, or otherwise controlling, gramophones comprises a member moved in conjunction with the tone-arm and a second member adapted to be moved periodically bv the tone-arm controlled member, the control device being operated when the periodical movement of the second member ceases as the result of an increase in the speed of movement of the tonearm. As shown, a lever 4 is pivoted about a screw 3 which passes through a plate 2 secured to the motor-board. The end of the lever 4 beneath the turntable 6 is provided with an arcuate projection 8 and a shaped tooth 7 and its other end has spaced fingers 9, 10 engaged by a pin 11 connected with the tone-arm so that the lever 4 is rotated therewith. The turntable boss 14, Fig. 6, is hollow and has a number of holes in its walls which house fibre pads 15 urged outwardly by a spring ring 16 so as to frictionally engage a sleeve 17 which carries a radial arm 18. The arm 18 is formed with a slot 19 in which is mounted a pin 20 provided below the arm 18 with a plate 22 which carries a small shaped block 23 having a cam surface 24 on one side and a flat 25 on the other. Pins 27 passed through the friction washer 21, the slot 19 and the plate 22 prevent turning of the block on the arm 18. In operation, when the pin 11 engages the finger 9, the lever 4 moves in conjunction with the tone-arm 13 and the rate of movement of the lever 4 is such that it is moved inwardly only so far as will permit the tooth 7 to contact, at each revolution, with the cam surface 24 on the block 23 as shown in Fig. 3. Thus at each revolution the block 23, as it moves to pass the tooth 7, is caused to slide a given distance along the slotted arm 18. When the stylus reaches a quick-pitch groove 30 at the end of a record, the movement of the lever 4 is so increased that the tooth 7 then engages the flat surface 25 of the block 23, Fig. 5, so that further rotation is prevented and the turntable is braked by the engagement of the pads 15 with the sleeve 17. The mechanism is reset when the tone-arm is swung outwardly whereby the tooth 7 slides the block 23 to the end of the slot 19, whereupon the tooth 7 is moved past the flat 25 against the friction of the pads 15. In applying the mechanism for effecting operations other than stopping the machine, use is made of the thrust imparted to the lever 4 when the rotation of the arm 18 is prevented.

Title: Computer organization
IPC: G06F15/80
Filed: 1964-08-04
Abstract: 1,026,890. Electronic digital computers. WESTINGHOUSE ELECTRIC CORPORATION. Aug. 4, 1964 [Aug. 5, 1963], No. 31535/64. Heading G4A. A computing system comprising an array of processing elements includes selection means for selecting processing elements for operation under the control of central control means. The system described is basically that disclosed in Specification 1,026,889, in which a two-dimensional matrix array of processing elements PE1-PE16, Fig. 1, each comprising two memory frames, an arithmetic unit and mode selection means, is operable under the control of central control means 10, only those elements which are in the particular mode signalled by the central control being operative. Data can be transferred between any processing element and its immediate neighbours in the array. The additional feature is that selection means 15 are provided in the form of row and column selectors 16, 18 so that data can be transferred via row buses RB1-RB4 and column buses CB1-CB4 between individual processing elements or any selected row or column of processing elements on the one hand and an input-output buffer 30 on the other hand. An operation such as the interchange of row and column data in the processing elements (corresponding to the mathematical operation of transposing a matrix) can thus be readily effected. Processing element.-Each processing element is basically as described in Specification 1,026,889, but the mode control circuit, Fig. 9, includes additional inputs on the row and column selection lines 21, 26 so that an enable signal EN is produced at 86 to render the element operative for data transfer to and from the input-output via the row and column buses only when the element is in the mode (indicated by the state of flip-flops 72, 74) corresponding to the particular one of four modes M1-M4 signalled by the central control and when the element is selected by signals on lines 21, 26. The enable signal EN is applied to STROKE (i.e. NAND) gates in a routing control circuit (Fig. 10, not shown), to control data transfer between the processing element and the row and column buses. Input-output buffer, Fig. 11. The inputoutput buffer 30, Fig. 11, comprises four flip-flops 120-126, the inputs of which are connected to the row buses RB1-RB4 column buses CB1-CB4 and input equipment and the outputs of which are connected to AND gates selectively controlled by signals CA, CB, CC from the central control, effective to route the data in the flip-flops to the row buses column buses and output equipment respectively. Test circuit.-A circuit (Fig. 12, not shown), is provided for determining whether processing elements are producing enable signals EN, the enable signal leads from all the elements being applied via a gating arrangement to four flip-flops. The circuit can operate in a " column test " or a " row test " mode for determining whether in an operation involving a selected row or a selected column, an element of that row or column is not providing the required enable signal.
