Title: Improvements in or relating to automatic means for stopping and starting talking or like machines
IPC: G11B17/02
Filed: 1928-11-26
Abstract: 307,047. Miksch, E., and Balder, G. March 3, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Stopping.-Mechanism operable by the movement of the tone-arm for stopping the drive either by applying a. brake or opening the motor circuit or separating the driving gear comprises a pivoted fall lever which is turned on its pivot by the movement of the tone-arm and supports a brake &c. actuating rod until playing of the record is completed, whereupon a supporting member for the fall lever releases it to fall downwards and permit the brake &c. actuating rod to operate. The fall lever 12 is pivoted to a lug 10 on a lever 5 which is turned on a pivot by a forked arm 9 moving with the tone-arm engaging a rod 7 fixed to the lever 5 and extending through the fall lever 12 with some side clearance. The lever 12 supports, during playing, the brake &c. actuating rod 24 and is itself supported on the flange 15 of a head 14 on the bent up end of a lever 6 engaging the forked end of the lever 5 and frictionally engaging a pivot 2 which is driven through a friction plate 29, gearing 16, 17 and 18 and a cord drum 20 from the driving motor so that the lever 6 turns more slowly than the lever 5 and the shoulder 15 remains below the lever 12. When, however, playing of the record is completed, the lever 12 falls off the shoulder owing either to the form of the innermost groove, or to the continued drive of the lever 6, or the inertia of this lever which may be weighted at 27 for this purpose, and the unsupported brake &c. actuating rod 24 then operates. A fixed support 25 with inclined end may be provided to support the fall lever 12 when carried with the tone-arm to the starting position; this permits movement of the tone-arm to find the starting-groove without fear of the lever 12 falling off the shoulder. The brake-operating rod 24 is pivoted and has a brake carried by jointed links which facilitate adjustment of the pad.

Title: Improvements in or relating to protective arrangements for electric power plant
IPC: H02H7/06
Filed: 1933-12-12
Abstract: 435,181. Systems for transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., ELLIS, G., and SAUNDERS, C. W., Magnet House, Kingsway, London. Dec. 12, 1933, No. 34965. [Class 38 (iv)] In an electric transmission system the power flow in the circuit connecting the generator and motor is reduced when the voltage and the current in the circuit both exceed predetermined values. In the arrangement shown in the Figure, resistance 13, which is normally shortcircuited, is inserted in series with the field 3 of the generator 2 by the opening of the relay 15 which is supplied with current from the mains 8, 9 when the switch 22 is closed due to the attainment of a predetermined voltage. The circuit through the voltage operating coil 23 is, however, only completed when the switch 27 is closed by the attainment of a predetermined current in one of the leads of the main circuit. In a modification, the reduction of power is effected by increasing the field strength of the motor by short-circuiting a resistance normally in series therewith. The input of motive fluid to the prime mover driving the generator may be reduced. In a further modification. the voltage and current controls may act on interlocking levers. Normal operation is not restored until the current and voltage have both attained lower predetermined values. The upper setting at least of each relay may be adjustable. In a further arrangement in which two generators each with its prime mover supply a motor, two parallel voltage relays, one for each generator, co-operate independently with a single current relay responsive to current supplied to the motor from one or both generators. The settings of the relays may be automatically adjusted when a generator or motor is disconnected as in the multiple generator and motor systems described in Specification 352,615.
