Filed: 1957-06-11
Abstract: 832,540. Pressure gauges. MANNING, MAXWELL & MOORE Inc. June 11, 1957, No. 18392/57. Class 106 (2). In a differential pressure responsive device in which a capsule 19 forms a partition separating two chambers 15, 16 within a rigid casing 13, 14, the capsule 19 comprises a rigid core 22, 25, 26, with a flexible diaphragm D, D' disposed adjacent each face of the core, and an incompressible fluid filling a central passage 34 and normally holding the diaphragms spaced away from the faces of the core and means 35 rigidly connecting the diaphragms, the core comprising a rigid central plate 22 to whose opposite plane faces are fixed, backing plates 25, 26 leaving marginal portions 28, 29 of the central plate 22 for leak-tight union with the diaphragms, each backing plate 25, 26 being formed with ridges and valleys complementary to those of a diaphragm so as to support the diaphragm and prevent injury thereto in response to excess pressure exerted on its outer surface. To avoid vibration due to rapid changes in pressure, the flow of liquid between spaces 43, 44 through the passage 34 may be restricted by a washer 45 having a central hole slightly larger than the rod 35 and guided to move freely perpendicular thereto. Compensation for the effects of fluid expansion with rise of temperature may be provided by a capsule E fixed to the rod 35 and communicating through a passage 42 with the passage 34. Communication between the spaces 43, 44 through further passages 46, 47 may be controlled by a needle valve 48 operated manually by a part 49. The rigid connection between the diaphragms may be in the form of a spool-shaped member 50a, Fig. 4, connected to a rod 54, and temperature compensation may be provided as before or by a capsule 56 housed in a cavity in the spool. The diaphragms D, D<SP>1</SP> may be of stainless steel only 0.005 inch thick and the corrugations in a diaphragm may be formed by shot peening or by the application of excess pressure forcing the diaphragm against its backing plate stressing it beyond its elastic limit. The capsule E may be formed by welding two flat discs together round their peripheries and then forming corrugations therein. Movements of the rod 35 due to differential pressure changes may cause movement of a magnetic mass in an electrical coil connected to an electrical instrument or they may rock a lever pivoted by a sealing diaphragm to operate a valve outside the casing in a pneumatic relay system.

Abstract: Epoxy resins are used to impregnate and coat ropes of inorganic non-metallic fibres, e.g. glass fabrics, the resin being thinned in a mixture comprising 300 parts (by weight) methyl or ethyl acetate, 30 parts diacetone alcohol, and 170 parts toluene or xylene, or being modified to increase flexibility by copolymerization with a liquid polysulphide polymer in the presence of an amine curing agent, or being modified with a polyamide.  The ropes are used for staying poles for electric power lines.ALSO:The whole or the upper part of a stay for a pole in an overhead electric power line consists of a rope or ropes having cords or rovings of non-metallic inorganic fibre of high tensile strength, the rope or all the cords or rovings, or the rope and all the cords or rovings being impregnated with a water repellant, electrically insulating material.  The rope, cords, or rovings may also be coated with the material, or the rope may have an extruded sheath of water-repellant, electrically insulating material. The construction eliminates the need for inserting insulators in the stay, and permits the stay to be attached to the pole at the centre of lateral pull of the line.  The stay may have collars of water repellant insulating material to increase the surface leakage path.

Title: Process of treating malleable cast iron to improve its physical properties
Filed: 1923-07-17
Abstract: 227,873. Marks, E. C. R., (Ohio Brass Co.). July 17, 1923. Drawings to Specification. Coating: galvanizing.-In a process for treating cast iron which has already been malleahleized, preparatory to glavanizing and sherardizing, the iron is heated to a temperature in excess of that which will cause the iron to be embrittled and quenched before the carbon-combining or critical temperature is reached. The iron so treated may be galvanized in a bath of molten zinc at a temperature not exceeding 482‹ C. or may be sherardized by being placed in a slowly-rotating drum in contact with zinc dust or oxidized zinc containing 80-92 per cent of zinc and heated to 349-377<‹> C. for several hours. After galvanizing, the surplus zinc is shaken off from the articles which are quenched in air, water, oil, &c.

Title: System for setting telecommunication switches by marking
IPC: H04Q3/42
Filed: 1956-06-15
Abstract: 787,170. Automatic exchange systems. COMPAGNIE INDUSTRIELLE DES TELEPHONES. June 15, 1956 [June 22, 1955], No. 18528/66. Class 40 (4). The arrangement described in Specification 665,391 for preventing the incorrect setting of switches which are controlled over a common marking multiple is modified in the manner shown in Fig. 10. When a selector S1, say, takes up the correct position as marked by the switch M1 in the controlling register E1, relay B1 vibrates its contact b11 but relay A1 remains operated and connects up C1. If two selectors S1, S2 controlled by registers E1, E2 pick up incorrect markings the two test circuits are in series and both B1 and B2 vibrate. At a time when one, say B1, is operative and the other is not, there is a circuit from battery U2 for the lower winding of B1 which operates fully, locks over its upper winding and connects in F1. Relay A1 is thus disconnected and the high resistance of B1 (lower) in series with F1 brings down A2, so that the selectors do not stop. In another embodiment, Fig. 8, employing similar circuits, a switch Ch is set repeatedly in succeeding positions of a sequence switch D in accordance with markings applied over a common multiple by a switch M which is set by digits representative of the wanted exchange and may have several contact rows. In this case the lower winding of relay B is of low resistance on account of the rectifiers in the marking circuits and relay F is of high resistance.

Abstract: 1,150,182. Feeding webs. DRUCKMASCHINENWERKE LEIPZIG VEB. 25 April, 1967, No. 18917/67. Heading B8R. In a web-unwinding arrangement wherein the action of a brake 12 on the hub of the supply roll 1 is controlled by a dancer role Y, the roll Y is situated between two conveying means 4, 5 and 8, 9 which feed the web 2 at the same speed. Thus, the tension in the web 2 between the two conveying devices remains constant being due solely to the loading by the roll 7, so that if the braking effect is too great, the web length between the roll 1 and rollers 4, 5 increases, but decreases after the web passes beyond the rollers 4, 5 thus raising the roll 7 and decreasing the braking effect. The reverse happens if the braking effect is not great enough. As shown, a spring-pressed roller 3 engages the web 2 between the supply roll 1 and the rollers 4, 5 to take up small variations in web tension and a guide roller 6 is provided between the driven rollers 4, 5 and the dancer roll 7.
