Title: Improvements in or relating to film sound recording apparatus
IPC: G11B7/00
Filed: 1933-08-31
Abstract: 424,793. Optical sound - recording apparatus. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Miller, R. A.; 628, Stelle Avenue, Plainfield, New Jersey, U.S.A.) Aug. 31, 1933, No. 24228. Convention date, Sept. 15, 1932. [Class 40 (ii)] Relates to apparatus for recording sound on a film of the kind employing a light valve having two vibratory conductors adapted to move in a magnetic field. According to the invention, the conductors are independently supplied with operating currents in such a manner that one conductor vibrates in accordance with the instantaneous variations of the soundmodulated currents, whilst the other conductor is deflected in dependence on the envelope of the amplitude variations of the sound currents. In the arrangement shown, a portion of the sound-modulated output of an amplifier 3 is further amplified at 4, and applied through a transformer 5 to one ribbon 8 of a light valve. The other ribbon 18 is fed from a battery 16 with steady current on which is superposed rectified and smoothed currents derived from another portion of the amplified sound currents through a rectifier 11-14, condenser 15, and resistance 22. By this means, the ribbons 8, 18, which control the light beam transmitted from a lamp 24 to a film 28, are independently vibrated, the comparatively slow movements of the ribbon 18 being such that the mean exposure of the film is always as small as possible.

Title: Improvements in brake mechanism for automotive vehicles
IPC: B60T13/48
Filed: 1928-08-23
Abstract: 296,780. Bragg, C. S., and Kliesrath, V. W. Sepb, 8, 1927, [Convention date]. Fluid-pressure.-In brake operating mechanism for vehicles wherein the chambers on both sides of the brake piston are adapted to be subjected to the suction of the engine, the engine is provided with two or more separate suction passages each arranged to supply fuel to certain of the engine cylinders and the suction pipes from the two sides of the brake piston are connected to different suction passages of the engine. A six cylinder engine is shown in which a separate suction passage 61, 62, 63 each with its carburettor 64, 65, 66 and throttle 67, 68, 69 is provided for each pair -of cylinders. The chamber of the brake cylinder 1 on one side of the piston 3 is constantly connected by a pipe 26 to the suction passage 62 and the chamber on the other side of the cylinder is normally connected through the operator's three-way control valve 28 to the suction passage 63. To apply the brakes the plug of the valve 28 is turned to cut off the pipe 27 from the suction passage 63 and connect it to atmosphere by a port 34. The valve may be turned to a position in which all the porte are blanked to hold the brakes applied and it is returned to the normal position to re-connect the pipe 27 and suction passage 63 to release the brakes. By this arrangement stalling of the engine is prevented since air is not drawn into more than one of the engine suction passages from the brake cylinder 1 at the same time. For this reason, only two separate engine suction passages may be provided, to each of which one of the suction pipes 26, 27 is connected. Further since the application of the brakes is effected by the admission of air to one side of the piston the rapidity of this action is not affected by the fact that not all the engine cylinders are used for exhausting the brake cylinder. Pipe connections 126, 127 and 226, 227 with cut-off cocks 126<a> - - 227a, for additional brake cylinders of which one 101 is shown may be provided. The additional cylinders may be disposed on the same or on trailer vehicles and are operable by the same valve 28.

Abstract: 1,108,486. Polyethylene terephthalate films. E. I. DU PONT DE NEMOURS & CO. 8 June, 1965 [8 June, 1964], No. 24274/65. Heading B5B. Biaxially stretched, heat-set films are made from polyethylene terephthalate having an intrinsic viscosity greater than 0À82, e.g. 0À83 to 1À05. The polymer having been formed into a film, the film is stretched, to over twice its original length in both the longitudinal and the transverse directions. It is preferably stretched in both directions to between 3 and 6 times its original length. The polymer may be prepared by solid phase polymerization according to U.S.A. Specification 2,534,028 and may be cast or otherwise formed, biaxially oriented and heat set by techniques known in the art. In an example the powdered polymer is formed into films at 280‹ C. stretched at a stretch ratio of 3 in both directions at 105‹ C. and heat-set in frames at 200‹ C. for 2¢ to 5 minutes. It is stated that films of polyethylene terephthalate of intrinsic viscosity over 0À75 have probably never been made and that in present day commercial films the polyethylene terephthalate generally has an intrinsic viscosity of 0À60 or lower. The films are stated to be particularly suitable for use in the production of computer cards and for packaging on account of their durability.
