Title: Improvements in and relating to safety arrangements for rontgen apparatus
IPC: H05G1/54
Filed: 1927-10-10
Abstract: 278,757. Otto, W. Oct. 9, 1926, [Convention date]. Cut - out arrangements.-A safety device for interrupting the current supply to a R÷ntgen tube in the event of excessive increase of the current intensity such as occurs in the case of a short circuit or of breakdown of the resistance of the tube comprises an electromagnet switch e included in the primary circuit of the supply transformer b, and coupled to the secondary circuit of the supply transformer through a transformer c, the coils of which are insulated to prevent the passage of high voltage current. The switch e is an automatic circuit breaker which must be re-set by hand; it does not respond under normal intensity conditions, but is actuated if the intensity increases excessively as a result, for example, of a person p touching simultaneously both high-voltage terminals of the transformer b. The device is also applicable to tube supply systems in which one terminal is earthed.

Title: Improvements in or relating to lift controlling mechanisms
IPC: B66B1/16
Filed: 1933-10-05
Abstract: 426,386. Lifts. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, SMART, N. C., and MOSS, B. F., c/o General Electric Co., Stoke, Coventry. Oct. 5, 1933, No. 27026/34. Divided out of 426,492. [Class 78 (ii)] [See also Group XXXVIII] Electric plant.-A floor selector for a liftcontrolling system comprises two uni-directional electromagnetic step-by-step switches which are stepped by impulses transmitted from the lift during its travel, all " up " impulses being fed to one switch, whilst all " down " impulses are fed to the other, the switch which is not being impulsed hunting to take up a position corresponding to the other. As shown, operation of one of the call-buttons PA-PF causes a uni-directional call storage switch C to step by self interruption at c until its contact arm reaches the appropriate contact on a bank C1. A second bank C2 of the call-storage switch is connected with a potentiometer resistance, and banks US2 and DS2 of the uni-directional " up " and " down " floor selector switches, the bank appropriate to the direction of travel being determined by contacts a1 of a switch A controlled by contacts of the " up " and " down drive contactors UR, DR. Lack of correspondence between switch C and either of switches US, DS causes energization of a three-position relay B in the appropriate direction to energize one of contactors UR, DR, and a contactor E controlling the brake magnet BR, so that movement of the lift in the required direction is initiated. As the lift passes suitable points between each floor, an inductor plate relay R operates its contacts r1 which sends impulses to the operating magnet of the appropriate switch US, DS as determined by the contacts a2, a3 of the switch A. As the destination floor is approached, relay B is de-energized to cut off the driving motor, but E remains locked at contacts sd2 of a relay SD and q1 of a floor levelling inductor relay Q, until the destination floor is reached, when contacts q1 open to release the brake and stop the lift. Relay SD remains locked via contacts sd3 and a time impulse circuit TD for a sufficient time to allow the lift gates to be opened, after which SD is de-energized so that contacts sd1 close and permit further calls to be stored. Gate switches JA-JF are provided to prevent operation of the lift motor unless all gates are closed. In order to cause the floor-selector switch which is not directly operated by the lift to be brought into correspondence with the other, interconnected contact banks US1, DS1 are provided and are brought into operation by the opening of contacts e3 of relay E1, switch S becoming re-energized and opening its contacts s1 to stop the self-stepping of the following switch when correspondence is established. The switches US, DS may be of the type described in Specification 349,180, [Group XXXVII]. Specification 354,847, [Group XXXVII], also is referred to.

Filed: 1934-09-22
Abstract: 441,030. Duplicating photographic sound-records. FILM OZAPHANE, 5, Avenue Percier, Paris. Sept. 22, 1934, No. 27263. Convention date, Oct. 14, 1933. [Class 40 (ii)] [See also Group XX] A number of sound-films are obtained from a single film bearing one or more variable density photographic records by dividing the latter up longitudinally in such a manner that the single sound track portion or each such portion on the film which is divided is cut into strips, each of which constitutes a separate sound film. The film so divided is preferably a regenerated cellulose film, sensitized by a mixture of a diazo compound and a phenol and developed in an ammoniacal atmosphere after being printed photographically from a record on a film bearing a wide track ; alternatively, the printing of the original wide record may be effected photo-mechanically. The whole process is preferably carried out as follows. Starting with a 35 mm. sensitized celluloid film, a single sound track of 24 mm. width is recorded thereon either by a direct electro-optical process or by photographic copying with enlargement from a record of normal width. The wide record thus obtained is printed on to a sensitized regenerated cellulose film, and the print is then divided longitudinally into narrow bands bearing identical records, e.g. twelve 2 mm. bands or twenty-four 1 mm. bands. The Figure shows an apparatus suitable for reproducing sound from a narrow film obtained as described. The film G passes over two flanged rollers A, B over which it is drawn under slight tension by a uniformly-driven rubbered drum F. Between the rollers A, B, the reproducing light beam, acting on a photoelectric cell K, is transmitted through the film by suitable means, such as the optical system E ; or light illuminating a part of the film may be projected on to a slit arranged in front of the cell. The Specification as open to inspection under Sect. 91 states also that "instead of a single variable density record of large width, there might also be reproduced on the celluloid film serving as a matrix, a very large number of very narrow and adjacent identical records of variable or fixed density. Each elementary phonofilm when cut up would then carry a certain number of these elementary recordings." This subject-matter does not appear in the Specification as accepted.
