Patent GB-359510-A (GB)
IPC: G11B17/00
Filed: 1930-06-11
Abstract: 359,510. Sound-reproducing apparatus ; associated working with kinematographs. FRIESS, H., 232, Friedrichstrasse, Berlin. June 11, 1930, No. 17902. Convention date, July 3, 1929. [Class 40 (ii).] Relates to sound - reproducing installations, particularly for working in association with kinematographs, in which an automatic changeover from one gramophone or the like to another is effected. According to the invention, a device is used for bringing about the transition, comprising a potentiometer resistance m arranged in circular formation and coacting with a contact arm m which is adapted to rotate in one direction only. Two terminals r, s of the resistance are connected respectively to one pole of one or other of the gramophone pick-ups u, k, the other poles of the pick-ups being connected together and to the contact arm n. In the arrangement shown, the arm n is carried by one part 1 of an electromagnetic clutch, the other member of which, p, is mounted on a shaft t driving both gramophones. When no current is flowing through the magnet p, the arm n rests on one of the points r, s, and only one pick-up is in action, operating a loud-speaker 10 through an amplifier 9 connected to the potentiometer. As soon as a contact o on the film z closes the circuit of a relay v, the latter completes a circuit from a battery 8 through the magnet p, and the member 1 bearing the arm n is raised and rotated by the shaft t. The circuit of the magnet p is broken as soon as the arm has made half a revolution, by which movement a change-over from one pick-up to the other is effected. The breaking of the circuit, which is brought about by one or other of two arms 2 projecting from the member 1 and operating a switch 6, causes the stoppage of the arm n. A further half-revolution of the arm occurs when the relay circuit is closed by the next film contact, the pick-ups being thus alternately put into operation. The invention is applicable to soundreproducing systems employing film records. The Specification as open to inspection under Sect. 91 (3) (a), describes also the use for effecting a gradual transition from one sound-reproducer to another, of a potentiometer having a sliding contact which is movable by hand over a straight resistance. It also refers to the provision, in the arrangement shown in the Figure, of means for raising and positioning the pick-ups automatically. This subject-matter does not appear in the Specification as accepted.

Abstract: 618,233. Plant; regulating. ANGLOIRANIAN OIL CO., Ltd., and TAYLOR, H. B. July 14, 1945, No. 18047. [Classes 7 (ii) and 7 (vi)] In a system of coupled engines having fuel metering pumps and comprising one "master" engine and at least one "slave" engine, means are provided for automatically ensuring equal load distribution. Pistons 1, 4, attached to the control rods of the fuel metering pumps of the "master" and "slave" engines respectively, control the ports 7, 8 in a pressure fluid circuit comprising the pipes 6, 9, and 16, the pressure in the pipe 9 being transmitted to a bellows 11 connected by a lever 21 to an eccentric pivot 20 of a lever 19 operated by a hand speed-control rod 17 to set the pilot valve 18 of the hydraulically operated "slave" engine fuel pump governor. The ports 7, 8 are chosen so that the ratio of their areas remains the same for equal movements of the pistons 1, 4, whereby the pressure in pipe 9 remains constant. If, in setting the engines for a definite load, the pistons 1, 4 move by different amounts, the alteration in pressure in pipe 9 actuates the bellows 11 to adjust the pivot 20, thereby causing the governor 18 to set piston 4 in its right position, automatically correcting the "slave" engine fuel supply. The pistons 1, 4 may be hollow and contain ports co-operating with the ports 7, 8, in which case the rod 2 may rotate to vary the area of these ports. If there is another "slave" engine, it is controlled in a similar manner by a second piston 12 connected to the piston 1, the pressure fluid entering by the pipe 13 and flowing by the pipe 15 to a device similar to the valve 4 on the other "slave" engine.
