Title: Improvements in leading-in units for electric lamps
IPC: H01J5/32
Filed: 1950-05-30
Abstract: 671,178. Leading-in conductors for electric lamps &c. LUMALAMPAN AKTIEBOLAG. May 30, 1950 [July 1, 1949], No. 13487/50. Class 39(ii) In making leading-in conductors for electric lamps and discharge devices, wherein wires 1 are welded to the ends of a strip 3 of metal foil and embedded in quartz, the ohmic resistance at the welded junctions is reduced by surrounding them by a baked layer 2 of metal powder. The layer may consist of tungsten powder suspended in methyl alcohol or other readily evaporable vehicle. A series of such units may be formed in a length of quartz tube which is subsequently sub-divided. Fig. 1 shows a chain consisting of alternate lengths of tungsten wire 1 and molybdenum foil 3 which have their welded junctions surrounded by a baked layer of metal powder and are then pushed into a quartz tube 5. The tube 5 is heated until soft, and compressed radially except at intermediate parts 4. The tube is subsequently severed at the parts 4, thus forming a number of individual leading-in units. Fig. 2 shows two such units 6, 7 respectively fused end-on into the quartz envelope 9 of an electric discharge device, an electrode 8 being mounted on the inner wire 1 of the unit 7 whilst the corresponding wire of unit 6 provides an auxiliary 'starting electrode. In a modification, Fig. 3, (not shown), a pair of parallel leading-in conductors, with welded joints coated in the manner described, are sealed within a common quartz leading-in unit which is fused to the end of a discharge tube.

Abstract: 543,549. Vibration-dampers. BORG-WARNER CORPORATION. Aug. 27, 1940, Nos. 13530 and 13531. Convention dates, Oct. 21, 1939 and Oct. 23, 1939. [Class 108 (iii)] [Also in Group XXIV] A centrifugal force operated mechanism includes a mass 15 of divided solid material e.g. small balls, positioned in a rotatable chamber defined by two rotary elements 5, 7, axially movable relative to each other, one of the axial end walls 14 of the chamber being angularly disposed toward the other end wall to change the centrifugal force of the solid mass 15 into pressure in a substantially axial direction whereby the mass 15 tends to force the rotary elements apart and press one of them against friction means. As shown for a vibration damper the element 7 is keyed to a sleeve 2 on a shaft 1. The sleeve 2 has a collar 3 and between the latter and the member 5 which is made massive is friction material 6. A spring 10 applies pressure to the mass 15 and presses the member 5 against the material 6. As the rotary speed increases the centrifugal force of the mass 15 increases to increase the pressure on the friction material 6 and thus damp rotary vibration.

Filed: 1970-03-20
Abstract: 1307942 Tubes J R HANRAHAN JNR 20 March 1970 [1 April 1969 5 March 1970] 13726/70 Heading F2P [Also in Division A5] A tube for use in the production of an orthopaedic cast comprises a layer of stretchable tubular air-permeable fabric and a tubular barrier layer of a flexible, inert, liquid-impermeable plastics material attached to said fabric layer in such a manner that the plastics material does not materially reduce the stretchability of the fabric. To form a cast, such a tube, with the barrier layer outermost and with an outer layer of stretchable, tubular, air-permeable fabric completely covering the barrier layer, may be applied to an injured member, an initiallyfluent layer of rigid-resin-forming composition then being applied to the outer fabric layer and the composition cured to form a rigid resinous layer at the outer surface of the outer fabric layer. Such a three-layer tube may be formed by spot-adhering an aluminized plastics layer 45 on to part of a length 11 of fabric material sleeve using a heated roller 41 pressed against a rotated mandrel 40, the barrier layer assuming a corrugated form on removal of the fabric sleeve 11 from mandrel 40, the free part 47 of the sleeve 11 then being folded back over the barrier layer to form the outer fabric layer. The barrier layer may be attached to one or both fabric layers by heat activatable adhesives or by heat-bonding. Windows may be provided in the cast. The cast may be rendered weightbearing by applying fibreglass tape over the tacky resin, and by applying more resin over the tape after setting of the initial resin layer. The fabric layers may be made of knitted cotton, acrylic fibres, crimped filaments and yarns or a Terry fabric. The barrier layer may be a synthetic rubber, or polyethylene or polyethylene terephthalate polyester. The resin may be a polyurethane, water-reducible polyester, or a phenoxy resin, for example.
