Patent GB-894684-A (GB)
Title: Improvements relating to fastenings
Inventor: KNIGHT CHRISTOPHER ROY
IPC: F21V17/16
Filed: 1959-09-28
Abstract: 894,684. Releasable fastenings. ALLOM BROS. Ltd. Sept. 28, 1960 [Sept. 28, 1959], No. 32933/59. Class 44. A fastening for releasably securing an electric light or other fitting 21 to a support 9 comprises a base member 5 adapted to be attached to the support and a catch member 14 which is guided for longitudinal movement on the base member between a locking position and release position, the catch member when in the release position being capable of limited lateral movement for releasable engagement with the fitting and means for resiliently restraining the catch member from longitudinal movement in both its locking and release position. As shown the restraining means is a toggle mechanism. The end of the catch member, which is extended in the release position, is formed with a slot to receive a tongue 19 carried by the fitting for the purpose of holding the fitting to the fastening. As shown the catch member is guided for the longitudinal movement between a flange 7 on the base member and a lug (not shown) which is pushed out from the material of the base member. The base member is provided with an L-shaped slot 23 to which the catch member is connected by means of a pin 24. Also connected to the pin 24 are two arms 35 which are coupled to a slide 28 which is connected by means of a pin 29 with a slot 30 in the base member; the slide is loaded by means of a spring 34 and the spring loaded slide and arms 35 constitute the toggle mechanism. When the catch member is in its extended position the short arm of the L-shaped slot 23 permits the limited lateral movement of the catch member against the pressure of the spring 34. This limited lateral movement permits the engagement and disengagement of the catch member and the tongue 19. Two fastenings are normally used one on each side of the fitting 21.

Title: Improvements in photosensitive glasses and articles made thereof
IPC: C03C4/04
Filed: 1947-12-16
Abstract: 636,152. Photo-sensitive glass. CORNING GLASS WORKS. Dec. 16, 1947, Nos. 33149 and 33150. Convention dates, Sept. 9, 1946. [Class 98 (ii)] [Also in Group XXIII] Photosensitive glasses, wherein an image or design on a clear background may be produced by subjecting selected portions of the glass to u.v. radiation (e.g. by interposing a photographic negative between the glass and the source of u.v.) and then heating the glass, contain at least one of the metals gold, silver or copper as the sensitizing agent and sufficient lithium or barium to produce, on heating the glass to a predetermined temperature after irradiation, crystallites of lithium disilicate, or barium disilicate, which cause opacification of the irradiated portions. Colouration develops at a temperature lower than that at which opacification occurs; by adjusting this temperature and/or adjusting other variables such as the amounts of the constituents and the intensity and/or duration of the irradiation, different kinds of images or designs, all on clear backgrounds, may be produced. These images or designs may be coloured but unopacified, coloured opacified, white opacified, or superficially coloured but unopacified (i.e. on the surface of the glass) superimposed on an identical opacified image or design in the thickness of the glass. Particular ranges comprise (1) 10-25 per cent Li 2 0 and at least .004 per cent Au or .025 per cent AgCI or .04 per cent Cu; and (2) 50-65 per cent Si0 2 , 5-15 per cent alkali metal oxide, 15-45 per cent BaO and at least .004 per cent Au. The inclusion of other substances such as Ca0 2 , Sn0 2 , Sb 2 0 3  is also discussed and in some cases up to 4 per cent AI 2 0<SP>3</SP> or up to 3 per cent of B 2 O 3,  CaO, MgO or ZnO, or up to 12 per cent SrO may be included.

Abstract: 300,660. Vaurs, B. Nov. 17, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Locking.- A locking device for bolts in which rotation of the bolt is prevented by balls, which, positioned or not by a washer, are forced into the bolt head and face of the work on tightening up. The nut is held by the bent up lugs of a washer which is itself prevented from turning by bolts tightened up between it and the work. Two balls 10, Fig. 3, are held in a thin washer 11. When the bolt is tightened up these are indented both into the bolt head 8 and into the work, and a claw 15 prevents the washer 11 from revolving. The nut 9 is held against rotation by bent up lugs 14 in the washer 12 which is itself held by an indented ball 13. In a variant the washer 11 may be omitted. The indentations may be prepared by using a jig 16, Fig. 5, which carrying balls 17 could be tightened on the work in a preliminary operation.

Abstract: 918,481. Injection moulding. FOSTER, YATES & THOM Ltd. Dec. 1, 1961 [Oct. 3, 1960], No. 33886/60. Class 87(2). An injection moulding machine consists of an injection cylinder 3 with a front plate 1, in front of which is a telescopic section comprising a fixed tubular part 4 connected to the front plate 1, a sleeve part 7 sliding on the part 4, and a nozzle part 8 sliding within the sleeve part 7. The nozzle is brought into sealing engagement with the mould orifice by means of fluid operated pistons 19, 20. The nozzle part 8 is kept in a forward position in the sleeve part 7 by the pressure of the plastic until it comes into contact with the mould, when the nozzle 8 is displaced rearwardly in the sleeve 7 and the channels 10 connect with the larger bore 11 allowing plastic to flow. As sleeve 7 slides forward over fixed portion 4 a cavity is left and when the nozzle 8 engages the mould and is displaced rearwardly this cavity is filled up. By suitable choice of diameters of parts 4 and 8, and the introduction of a valve in fixed part 4, a pressure can be built up inside sleeve 7 to assist injection. The apparatus may be used for high pressure short injection by plugging the end of the part 4 and providing radial apertures near the plugged end (see Fig. 3, not shown).
