Patent GB-709189-A (GB)
Abstract: 709,189. Calculating-apparatus ; transfer mechanism. BURROUGHS CORPORATION. July 26, 1949, No. 9794/52. Divided out of 709,181. Drawings to Specification. Class 106 (1) In a calculating-machine having two totalizers and means comprising a relatively movable portion, such as a travelling paper carriage, for printing in different columns of a record material, two mechanisms are variably presettable to determine automatically the nature of the operations to be performed in one totalizer in the different columnar positions of the recording means, one of these mechanisms being effective when the total in the other totalizer is of one sign but ineffective when this total is of the opposite sign. The subject-matter of this Specification is fully disclosed in Specification 709,181 to which reference is made, and it is pointed out that a short control projection in place of a medium projection in lane 16 will restrict the movement of the corresponding control mechanism to cause a non-add operation in the rear totalizer instead of subtraction. It is thus possible to accumulate in the rear totalizer, an algebraic total of the totals taken from the front totalizer, or the sum of the positive or negative totals. Specifications 709,188 and 709,190 also are referred to.
Patent GB-729672-A (GB)
Abstract: 729,672. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Nov. 20, 1952 [Nov. 21, 1951], No. 29375/52. Class 97 (3). [Also in Group XXXVII] A gyroscopic apparatus has means for restraining movement of the rotor about one of its suspension axes, said means being rendered inoperative a predetermined time after the rotor has been set spinning, an erection system, and means for energizing said system at the time said movement-restraining means are rendered inoperative. In the directional gyroscope shown, the rotor is spun by a motor 6, is mounted on gimbals, the outer of which is geared at 27 to an indicator (not shown), and is maintained with its spin axis horizontal by a torque motor 11 controlled by a pendulous switch 13. A brake 25 mounted on one 15 of a pair of bimetallic elements 15, 17 engages the gear 27 to prevent movement of the outer gimbal as the rotor is started or is stopping. A resistance heater 31 surrounds element 17 and is connected to the motors 6, 11 and a power source via switch 33. Closure of the latter switch thus energizes the heater and causes the rotor to spin, and when the rotor has attained about half its operative speed, the elements 15, 17 flex sufficiently to release brake 25 and thereby close switch contacts 37, 39 and energize the erection motor 11. When switch 33 is opened, motor 11 becomes de-energized and the brake 25 is applied to the gimbal.

Title: Disc reproducing system for compensating mechanical imperfections
IPC: G11B3/10
Filed: 1978-12-12
Abstract: The effects of vertical perturbations of a gramophone disc record surface resulting from e.g. record warp and rumble are reduced by sensing the perturbations and compensating therefor by closed loop or open loop means. Thus a reference path adjacent the groove tracked by the main stylus may be tracked, e.g. by a supplementary stylus riding on the lands of the disc surface or photoelectrically. A reference path signal may then be derived by a reference path sensor 104, and this signal is then applied to a preferably closed loop servo 95, 98, 100, 112, 114, 97 which moves the disc 9 itself up and down to tend to null out the reference path signal. Alternatively the compensation is applied by causing the tone arm to track the reference path by a servo technique or by mechanical coupling within the cartridge or electrically by subtracting the reference path signal from the main stylus signal, or by a combination of such techniques. <IMAGE>
