Title: Improvements relating to fluid operated electric switches
Inventor: WILLIAMS LEONARD
IPC: H01H35/38
Filed: 1955-11-29
Abstract: 838,291. Fluid-actuated switches. ENGLISH ELECTRIC CO. Ltd. Nov. 21, 1956 [Nov. 29, 1955], No. 34119/55. Class 38 (5). At the same time as fluid is admitted to the working face 19c of a piston 19, fluid also passes through duct 26 in the cylinder to the rear, smaller face 19d to retard the movement of the piston until a wider part 19a thereof covers the duct 26 and simultaneously a narrower part 19b opens an exhaust port 27. At this moment movable bridging contacts 24 engage fixed contacts 13 with a snap action. At the end of the movement the piston engages a sealing ring 29. In the opening movement, the ducts 26 and port 27 are uncovered at the moment of contact separation, whereby pressure - fluid assists the spring 25 in imparting a rapid movement. A further bridging contact (not shown) may be mounted on the other side of the insulating carrier 23.

Abstract: 918,855. Eddy current brakes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 8, 1959 [Oct. 11, 1958], No. 34154/59. Class 35. In a vehicle multipolar permanent-magnet eddy current brake comprising a permanent magnet structure 2 secured to a shaft 1 rotatable with the vehicle wheels and coaxially surrounded by a member 4 in which eddy currents are produced, the structure and member being relatively axially displaceable so as to release or apply the brake, the structure 2 has axiallyextending ventilator vanes 9 and the member 4 has cooling fins 7 and is coaxially surrounded by a closing member 10 arranged to cause a cooling stream impelled by the vanes to flow past the fins in a direction having both axial and radial components. As shown, a further magnet structure 3 and eddy current member 4 may be provided, and the stream direction is caused by the spacing between the closing members 10 which overlap the members 4, 5. The degree of ventilation is controlled in the same sense and in correspondence with the degree of braking by the consequent closure of the cooling air stream paths. The members 4, 5 are copper and are surrounded by iron rings 8. The structures 2, 3 may be similar to that in Specification 904,441. Specification 910,649 also is referred to.

Abstract: 430,403. Road - surface heaters. RANDS, F. C., and ALEXANDER, T. F. N., Windsor House, Kingsway, London. Nov. 28, 1934, No. 34228. [Class 107] A road - surface heating - machine comprises, in combination, an adjustable cowl 17, Fig. 1, one or more liquid fuel burners 6 arranged directly at or above the head thereof, an oil storage tank 7, an air compressor 9, a fuel connection 8 from the tank to the burners, and pipe connections 10, 11 for supplying compressed air to the tank and burners. An auxiliary supply of air to assist combustion and to force the flames downwardly on to the road surface is obtained by means of a fan 13 and a duct 14 leading therefrom. The adjustment of the cowl may be effected as shown, by bolts 18 and wing-nuts 19, the cowl being arranged at the foot of a vertical casing 4 provided with a perforated base-plate 20 through which the flames pass. The vehicle is fitted with rubber-tyred wheels 21 for ordinary travel, which are replaced by smaller metal wheels 22 when the machine is in operation. In a modification, the casing 4 can be raised and lowered by ropes leading to a winch mounted on the vehicle. In further constructions, the fuel tank and air compressor are mounted upon a separate vehicle from the cowl and burners. The cowl may be pivotally supported in an adjustable manner on a wheeled chassis or, as shown in Fig. 9, it may be suspended from an arm 33 fixed at 34 to a wheeled fulcrum frame 35. One end of the arm is adjustably secured to a support 36 and the other end is adapted to be manually operated for raising and lowering the cowl and for moving it from place to place.

Abstract: 290,134. Pate, G., and Laird, J. R. Dec. 19, 1927. Wire resistances, cored.-In an electric heating-element consisting of a rod bearing loosely threaded insulator discs carrying a coiled resistance wire, fracture of the discs due to expansion and contraction of the rod is presented by maintaining the discs in contact by the insertion of at least one bimetallic strip between an abutment on the rod and the adjacent insulation disc, the metals of the strip being so arranged that expansion and contraction of the rod are accompanied by expansion and contraction of the strip. Preferably, the strip is formed as a C spring. Fig. 2, with the metal having the greater coefficient of expansion constituting the interior surface. On the rod 1 of the heating elememt are provided two abutments, one a fixed collar 4 and the other a nut 5 on the other end of the rod.

Abstract: 1,113,628. Connector for coaxial cables. BENDIX CORPORATION. 11 Aug., 1665 [17 Aug., 1964], No. 34372/65. Addition to 1,113,352. Heading H2E. Two coaxial cables 12 are interconnected through two coupling members each of which comprises an insulating body member 24 and 43, a central conducting member 28 and 29, and an outer tubular casing member 18 and 40, each casing being secured to the semi-rigid outer conductor of the cable by an intermediate conductor 34 and 48 which may be soldered to the outer cable conductor and the casing. As in the parent Specification, any change in characteristic impedance of the line is avoided at step discontinuities in diameter of the central conductor by correspending diameter changes in the outer conductor, these larger diameter sections of the outer conductor being slightly longer than those in the inner conductor to prevent an increase in the voltage standing wave ratio. In a modification, Fig. 2 (not shown), for use with flexible cables, the intermediate member has a tapering end portion which is inserted between the cable braid and insulation and is held in place by a crimping sleeve and tube of irradiated polyethylene. The outer easing may be deformed to form a permanent mechanical connection with the intermediate member.

[Class 100 (ii).] In an engraving process utilizing a templet having a track or groove, and a cutter or similar tool, the plate or other member 1 to be engraved is rigidly attached to a metal or like templet 4 which is so disposed that a finger 6, having the same diameter as the tool 3, projecting from a plane supporting surface 5 can engage the track in the templet, the tool 3 being rotatably supported over the free face of the member 1, and the assemblage formed by the member 1 and templet 4 being capable of movement over the surface 5 with the finger 6 in engagement with the track in the templet. The member 1 is shown as a plate which may be painted &c. on one face, or it may comprise three sheets of material such as ebonite or celluloid, the upper one being opaque, and the lower ones transparent or translucent. Where three such sheets are employed the depth of the grooves to be engraved in the plate 1 to form letters, digits or signs may be limited to the thickness of the top sheet. The templet 4 is grooved to any depth. The templet and plate are placed on supporting surfaces in a loose frame 7, capable of movement over the surface 5, spaced pivoted arms 13 connected by a cross member 14 being resiliently pressed on to the plate 1 by a nut 18, which engages a stud 16 carried by the frame 7, and adapted to project through a hole in the cross member 14, a coil spring surrounding the stud tending to press the member 14 upwardly. An arm 21 pivoted in lugs 20 on the surface 5 carries a motor 22 on the shaft 23 of which is fixed the tool 3. The depth of the groove to be cut in the plate 1 is regulated by an adjustable sleeve 24 which surrounds the tool and is adapted to engage the plate 1. If desired, in addition to the weight of the motor and associated parts, means such as springs attached to the surface 5 and arm 21 may be employed to give additional downward pressure to the tool 3. Stops 31, 32 limit the downward movement of the arm 21.
