The envelope of the discharge tube is preferably provided with projections 8, formed, for example, by sealing sharp edged pieces of glass or quartz thereto, to prevent the sudden formation of vapour bubbles at the discharge tube. The gas in the vessel 1 may be air, in the proportion of 1 : 9 of the volume of water, at 20‹ C. and 1 atmosphere pressure. The dissipation of heat may be increased by cooling fins. Alternatively, the vessel 1 may be cooled by water, which may circulate in a closed circuit, or by a second closed vessel containing cooling liquid and a gas. A thermostat may be provided to operate an indicator or render the discharge tube inoperative. The vessel may be formed of a material to transmit light, such as glass or quartz, and may be in parts mechanically connected. The cooling liquid may also be chosen to act as a light filter. The discharge tube is mounted on the stem 2 of the vessel 1, by means of insulators 7 carrying the leads 5, and may have a filling of rare gas and mercury at about 80 atmospheres with an output of 500 watts.

Title: Improvements in or relating to joints for electric cables having anti-torsional armour
IPC: H02G15/08
Filed: 1960-07-20
Abstract: 903,448. Cables; insulating cable joints and terminals. PIRELLI S.p.A. July 20, 1960 [Sept. 2, 1959], No. 25256/60. Classes 36 and 38 (1). A joint for electric cables having armouring comprising a sheath of thermoplastic material enclosing a layer of metallic strands disposed parallel to one another and to the axis of the cable, wherein the individual armour strands of the two cable lengths are jointed by means of sleeve couplings deformed permanently by squeezing around the strands. The joint is formed by first removing the thermoplastic material 4 from the cones and metallic strands, joining the two cores 1, by any known method, bending the jointed cores into an arc with the strands disposed along a chord of the arc, and connecting corresponding strands of each cable length by staggered sleeve couplings, so that they will slip under sufficient tension. The cable is then pulled straight, the strands slipping through the couplings, after which the core is again bent without the strands slipping back through the couplings and the couplings squeezed tightly around the strands, supplementary safety couplings being added, if desired. The cable is then straightened under slight tension and the sheath of thermoplastic material around the jointed strands is restored.

Abstract: 885,593. Making brakes; riveting. GIRLING Ltd. July 22, 1960 [July 23, 1959], No. 25261/59. Classes 83 (2) and 83 (4). [Also in Group XXV] A method of permanently securing members together, comprises deforming an insert or inserts within recesses in adjacent faces of the members, the deformation being effected by external pressure on the members forcing them together. In an embodiment wherein a castiron brake ring 10 is to be secured to a steelmounting plate 11, an outwardly-diverging annular groove 12 is formed in each of the abutting faces of the members to accommodate a tubular eyelet 13 which is first placed in alignment with the grooves and then deformed into the grooves by pressing the members together. Any number of pairs of grooves and eyelets may be disposed at intervals around the members. Alternatively, a circular recess with an undercut edge is formed in each member instead of the inclined groove and the ends of the eyelet are flared or the base of the recess domed to facilitate the outward deformation of the eyelet. In another embodiment two braking rings 18 and 19 are secured to opposite sides of a mounting plate 21, Fig. 4, the eyelets 24 passing through clearance openings 23 in the plate. In a further embodiment, pegs 28, Fig. 6, are used instead of the tubular rivets and the pegs are deformed into inclined blind bores 29 formed in the brake ring 26 and the mounting plate 27. The bores may be oriented in different directions. The method is applicable for securing friction linings to brake shoes with or without an intervening layer of asbestos or other heat-insulating material.

Filed: 1963-06-28
Abstract: 1,040,946. Valves. TOMLINSON INDUSTRIES Inc. June 28, 1963 [Aug. 20, 1962], No. 25747/63. Heading F2V. In a valve body with a passageway extending therethrough with a valve seat therein and a cap-shaped closure member movable towards said seat upon a valve stem, the cap-shaped member has a transverse shoulder joining a closure nipple to a base portion clamped within the valve body and the free state dimensions of the closure member cap are such that the transverse shoulder portion is flexed beyond its free state position towards the seat when the valve is closed and, when the valve is fully open, the transverse shoulder portion is flexed beyond its free state position away from the valve seat. Outlet 12 and inlet 13 are obturated by closure member cap 30 pressed by spring 25 against seat 15 and raised therefrom upon stem 23 by the action of cam face 39 of pivotally secured handle 93; a flat cam face 26 thereon enabling the cap 30 to be locked in the fully open position. During assembly, the cap 30 is inserted in the body 13 to an extent determined by flared outer periphery 35 (Figs. 4 and 8, not shown) and gripped in position by axially projecting expander 50 upon bonnet member 21 which is screw-threaded upon body 13 and carries the stem assembly for a snap fit of the stem knob 27 within recessed portion 44 of the cap 30. Upon assembly, the stem forces the transverse shoulder portion 33 away from the free state and unstrained position 56 to the position 55, corresponding to closure, with the valve cap 30 upon the seat 15 and equalling about 1/3 of the total stem travel. When the valve is opened the position 57 is assumed, equal to a distance beyond the free state position 56 of about 2/3 of the total stem travel. This relationship, which can be altered, maximizes the life of the cap which remains in the closed position for substantially longer periods, and is claimed thereby to improve upon the prior art cap 30<SP>1</SP> (Fig. 12, not shown), wherein the transverse shoulder 33<SP>1</SP> is substantially flat in the free state corresponding to the valve closed position.
