Title: Improvements relating to apparatus for producing electrical impulses of very high voltage
IPC: H03K3/537
Filed: 1931-09-11
Abstract: 389,813. Charging and discharging condensers. BRASCH, A., 4, Clausewitzstrasse, Charlottenburg, and LANGE, F., 7, Reichstagsufer, both in Berlin. Sept. 11, 1931, No. 25565. Convention date, Sept. 11, 1930. [Classes 38 (ii) and 38 (iv).] Condensers.-An installation for generating shock voltages, of the kind described in Specification 344,862, in which condensers q are charged in series with resistances f and discharged in series through spark gaps, is immersed wholly or partly in an insulating liquid so that a compact construction may be obtained by utilizing the delay in breakdown which is a property of the dielectric. The spark gaps are in separate gas-filled chambers g which may be maintained under pressure ; by connecting all chambers to a common pressure source i, regulation and measurement of the voltage may be obtained by varying and measuring the gas pressure. The insulating liquid may be put under pressure, Fig. 2, to prevent leakage discharge at the condensers and to increase the dielectric strength of the solid dielectric ; the spark gap chambers g may in this case communicate with the liquid, and voltage regulation then be obtained by varying the liquid pressure. The installation may be arranged in an inner chamber d containing a high-grade insulating liquid, this chamber being enclosed in an outer container a with a lower quality dielectric, such as water. A series spark gap h is disposed in the inner chamber to keep the charging voltage from the poor dielectric. Objects, such as insulators l, to be tested may be placed within the container and an external insulating bushing avoided. A discharge tube similarly placed may be used to irradiate objects through a suitable window.

Title: Improvements relating to control valves for fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1932-09-15
Abstract: 407,092. Fluid - pressure brakes. LEECH, K. H., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Sept. 15, 1932, No. 25729. [Class 103 (i).] In control valves for fluid-pressure brakes, of the kind comprising an abutment which is subject to the brake cylinder pressure established by the valve and which transmits this pressure to the hand or foot of the operator, means are provided whereby the abutment is subject to the actual pressure in the brake cylinder or to pressure conditions derived therefrom in such a manner as to prevent any change in the reaction prior to the establishment of the changed pressure conditions in the brake cylinder. The valve shown comprises a lever 3 actuating through a spring 5 and abutment 6, release and application valves 13, 15. Normally the brake cylinder connected at 12 is open to atmosphere through the tubular rod 10 of the abutment 6. When the lever 3 is depressed the valve 13 seats on the rod 10 and the valve 15 is opened to admit compressed air from the reservoir to the brake cylinder through passages 19, 17, 12 past the strainer 18. The abutment 6 instead, as usual, being open to the space 11 about the valves 13, 15 is contained in a separate chamber 20 which is connected by passage 21 to the actual brake cylinder or to a point remote from the valve in the pipe leading to the cylinder. As soon as the cylinder pressure attains the value corresponding to the compression of the spring 5 the abutment is moved upwardly so that the valve 15 closes. Instead of providing the passage 21, a pressure in the chamber 20 corresponding to the cylinder pressure may be obtained by providing clearance between the rod 10 and its guide 9 so as to form a restricted passage between the chambers 11, 20, the chamber 20 being amplified by connecting a reservoir thereto. In a. further construction, the brake cylinder communicates through a restricted port with a chamber which is in direct communication with the chamber 20.

Patent GB-690926-A (GB)
Title: Improvements relating to printing on leather and other anisotropic materials
IPC: B41M1/40
Filed: 1949-10-07
Abstract: 690,926. Ornamenting. HOEY, R. M. COLCLOUGH Jan. 8, 1951. [Oct. 7, 1949] No. 25844/49. Class 93. [Also in Group XVI] A method of ornamenting anisotropic material such as leather, consists in transferring a pigment from a backing by blocking, the pigment being bound to the material by a flexible acrylic or vinyl resin. The backing may be coated with the resin in liquid form, as in the form of an emulsion, for example by passing the backing foil over a roller dipping into the emulsion. After drying, the coated foil is passed through a blocking machine and the resin is transferred to the material at the same time as the pigment. Alternatively, the pigment and resin can be mixed together and applied to the foil, or the material can be coated with the resin before the pigment is applied. The foil may consist essentially of paper, cellulose or glassine. Resins suitable are alkyl acrylates, alkyl methacrylates and copolymers thereof, for example, Texipol 110, Lankroplast, the resins sold under the Registered Trade Marks "Bedacryl" and "Synflex", or the vinyl acetate known as Fabo G 83, the word "Fabo" being a Registered Trade Mark. In one example, pigmented foil is run at 25 feet per minute through a bath containing an emulsion of Lankroplast to form a layer about 0.002 ins. thick over the pigment. The coated foil is applied to leather by a blocking machine, the block temperature being about 120 ‹C., and the pressure causing the block to sink slightly into the leather. A coating of lacquer applied over the pigment gives it a high finish and makes it resistant to abrasion and polishing. When pigment is applied in this manner to anisotropic material, the pigment does not crack and flake away on distortortion of the material, the resin taking up the local variations in distortion due to binding and stretching.

Abstract: 1,123,706. Toothed gearing. GENERAL MOTORS CORP. 8 June, 1967 [15 Sept., 1966], No. 26499/67. Heading F2Q. In a reduction gear for a turboprop engine, a ring rear 60 is supported by helical splines 72 on a flange 73 for limited axial movement between abutments 74, 77, the axial position of the ring gear 60 indicating the torque being transmitted. A plunger 88 is spring-pressed into engagement with fingers 81 extending from the ring gear 60, and a flange 92 at the outer end of the plunger may be connected to a suitable actuated device. Belleville washers 75, 76 are located between abutment 74 and a flange 78 on an actuating ring 79, which also has a flange 80 which bears against a split ring 83 on the fingers 81. Under no torque conditions, the inner margins of washers 75, 76 are deflected apart pushing actuating ring 79 to the right until its flange 78 engages the abutment 77. Under normal operating conditions, the torque urges the ring gear 60 to the left, to the position shown in Fig. 2, the Belleville washers 75, 76 being collapsed. The plunger 88 moves correspondingly. At a predetermined reverse torque, ring gear 60 is moved to the right causing flange 73 to engage washer 75 and urging the washers 75, 76 to collapse and move to the right until prevented by abutment 77. Thus the plunger 88 is moved to a third position, corresponding to reverse torque.
