Abstract: 609,211. Lamp caps and holders. BRITISH THOMSON-HOUSTON CO., Ltd. April 10, 1945, No. 8856. Convention date, April 12, 1944. [Class 38 (i)] A lamp base 23, Fig. 1, for a photoflash bulb of the type described in Specification 586,129, comprises a web portion 37 and a square rim portion 39 surrounding a circular cavity having an annular groove 41 for the reception of the neck 22 of a lamp bulb 21. The lead-in wires 24, 25 for the bulb pass through apertures 26, 27 in the web portion, their outer ends being sealed into further apertures 28, 29 so as to form two contacts 30, 31, the said apertures being so positioned that the said contacts are disposed eccentrically on the base. Two arcuate support-engaging flanges 43 are formed on opposite sides of the rim 39. Fig. 4 shows a holder for the base comprising a plate 56 having an aperture 57 shaped for the passage therethrough of the base, the latter then being rotated through 90 degrees so that the flanges 43 engage the under surface of the plate and the contacts 30, 31 engage leaf-spring contacts 58, 59 secured to the plate and having aligned grooves 60, 61 respectively, to prevent further rotation of the base. This holder may be modified, Figs. 6 and 7, (not shown) by the addition of two straight wire spring members disposed in slots along the straight sides of the aperture in the plate and projecting slightly therefrom so that subsequent to the straight forward insertion of the base, they clip-over the straight sides thereof. A further modification, Fig. 8, for a plurality of lamps, comprises a spring strip 72 having its edges 73, 74 bent back to form a slot for the reception of the square portion of the base when the latter is inserted through an aperture 78 in the central portion 75 of the strip. The base is then moved longitudinally of the strip, until the flanges 43 spring into a cavity 77. Figs. 10-12 (not shown) illustrate a similar modification in which the bent over edges of the strip have a square depression with which the square portion of the base registers after insertion through an aperture in the face of the strip and subsequent rotation. In further modifications of the base, the flanges 43 may be coplanar with the web portion 37 or the bottom of the base may be circular, the top in this case having two straight parallel surfaces for indexing. The Specification as open to inspection under Sect. 91 also shows a holder for the base. Fig. 4 (Cancelled), which is also disclosed in Specification 586,129, comprising circularlydisposed resilient spring fingers 44 having bevelled ridges 47 which snap over the base flanges 43 and retain the contacts 30, 31 in contact with a central, spring-loaded stud contact 45 and a helical spring contact 46, respectively. This subject-matter does not appear in the Specification as accepted.

Abstract: 758,555. Pressure gauges. BORZONE, D. April 5, 1954 [April 4, 1953; Nov. 5, 1953], No. 9939/54. Class 106 (2). [Also in Group XVIII] Apparatus for checking air pressure in air columns of tyre pressure service stations comprises in combination a mechanical pressure gauge 19, capable of measuring the pressure of any tyre, fitted to the free end of a compressedair pipe, a fixed open-ended mercury gate 4, 104 fitted in an air column 1 and adapted to check the air pressure of low-pressure tyres and valve means by means of which both gauges or alternatively only the mechanical pressure gauge 19 can be connected with the tyre to be checked, as required. In the embodiment of Fig. 1 compressed air is supplied from a tank 40 by feed pipe 112 through a trigger valve to the connector 9 which has an outlet valve and gauge 19 whose pressure chamber is connected through a cock, controlled by a lever 47, and hose 7 to a nipple communicating through a pipe 204 with one branch 104 of a U-tube containing mercury whose indicating branch 4 communicates with atmosphere through holes 405 round a cup 5 provided to catch any mercury ejected should the gauge be subjected to too high a pressure. The cup has a baffle plate 122, loosely fitting cap 305 and a gutter 505. In the embodiment of Fig. 5, the branch 104 of the mercury gauge communicates with the connector through a cock 6, pipe 204, nipple 7 and twin hose 8 while a tyre to be inflated or checked communicates with a compressed-air feed pipe 12, controlled by a stop cock 14, through the connector and twin hose 8, a nipple 13 and either a pipe 15 with a cock 17 or pipe 16 with pressure reducer 18, according to whether the cock 17 is open or closed to give a high pressure (85-100 pounds per square inch) or a low pressure (14-43 pounds per square inch) when a high pressure is required the mercury gauge should be cut out by closing cock 6 and preferably cocks 6 and 17 are combined in a single two-way cock to make the cut-out automatic. Any mercury ejected against a baffle 22 in a cup 5 falls into the cup and flows back into the tube 4, any particles carried by the air current collecting in a container 21. Possible oscillations of mercury in the gauge are damped by a valve 24 preferably a double-acting non-return valve with a ball or double-mushroom-shaped closure member movable with play between opposite seats without effecting a tight closure.
