Title: Process and apparatus for use in modifying glass and other materials
Inventor: PLUMAT EMILE
IPC: C03C21/00
Filed: 1968-02-27
Abstract: 1,218,403. Modifying glass and vitrocrystalline material. GLAVERBEL. 27 Feb., 1968 [27 April, 1967], No. 9493/68. Heading C1M. A body of glass or vitrocrystalline material is modified by causing ions to diffuse into at least one surface of the body from a contacting medium at a rate which differs from one zone to another over the area of the interface between the body and the medium so that the body is affected differentially substantially according to a predetermined pattern. In this way the body may be chemically tempered or coloured. The chemical tempering preferably results in an exchange of alkali metal ions and the diffusion may take place from a liquid medium in which the body is immersed, a coating medium on the body or a gaseous medium. In coating processes a medium of uniform composition can be applied differentially to form a coating of variable thickness according to a predetermined pattern, e.g. by a printing roller or plate, or if the medium is of paste-like consistency a uniform coating can be applied and an impress pattern formed thereon. A layer of medium of varying thickness may also be held against the body surface by a mould. The body may be covered with two or more different pastes having different concentrations of ions to be introduced into the body according to a predetermined pattern. The diffusion may be promoted by superimposing an electric field. The medium may incorporate a filler, e.g. kaolin, and also an ion-exchange material for taking up ions released from the body and generating further ions for diffusing into the body. The body may be first coated patternwise, selectively, or differentially with a diffusion restricting substance, e.g. petrol or another aliphatic oil, or with a diffusion promoting substance, and then the medium is applied over the whole surface. The body surface may be selectively or differentially precoated with a substance, e.g. copper or TiO 2 , which restricts deposition of the medium where such substance is present. The chemical tempering preferably takes place along a network of lines subdividing the body area, e.g. along oblique parallel lines which may have oppositely inclined lines, along a hexagonal pattern, or oblique zig-zag patterns. The body treated may be a sheet of sodalime or borosilicate glass. In an example a sheet of vitrocrystalline material of the composition in weight per cent: SiO 2 : 42À3; Al 2 O 3 : 31À2; Na 2 O: 10À4; K 2 O: 6À2; CaO: 1À8; TiO 2 : 7À4; As 2 O 3 : 0À7 is coated with a layer of hydrated china clay containing 10% KNO 3 , which is then dried in air to form a network pattern of fissures which are filled with china clay containing 50% KNO 3 . The coated sheet is heated in a furnace and cooled.

Title: Improvements in or relating to gas burners
IPC: F23D14/06
Filed: 1926-04-13
Abstract: 265,041. Frankfurter Gasges., and Schumacher, E. April 13, 1926. Atmospheric gas burners; flame spreaders and deflectors. - A heating burner utilizing high pressure gas-air mixture comprises a chamotte or like refractory plate, which is spaced apart from an object to be heated, the flames being directed into contact with the plate but maintained out of contact with the object, and the combustion gases being whirled between the plate and the object so that heating is effected by radiation from the plate and directly by the combustion gases. In one form, the mixture is supplied through a pipe 1, Fig. 1, to downwardly inclined jets 2 and the flames contact with a plate 4 having a raised edge 6 to whirl the combustion gases upwardly against the bottom of a utensil 3. An asbestos or like heatinsulating plate may be arranged underneath the plate 4. Secondary air may be drawn in through openings 7 or supplied under pressure through a central pipe 15, Fig. 3, to outlets 14 above the jets 2 or through an annular passage surrounding the pipe 1 and terminating below the jets 2. The latter may be replaced by a single annular outlet. In a second form, the gas-air jets 2, Fig. 2, are arranged separately, and preferably obliquely, around the edge of a plate 4 having a central projection 8 to whirl the combustion gases. In a third form, secondary air jets are provided in openings, or formed, preferably obliquely, in the rim of the plate 4, the jets in the latter case being supplied through a metal jacket covering the side or bottom or both side and bottom of the plate 4 so that the supply is preheated and radiation of heat horizontally and downwardly from the plate is diminished. Alternatively, the mixture may be supplied to the jets at the rim of the plate and the secondary air to the jets 2 at the centre. In a fourth form. burners having gas-air jets and secondary air jets are arranged around the rim of the plate.

Abstract: 393,395. Battery lamps. BURGESS BATTERY CO., Madison, Wisconsin, U.S.A. April 5, 1932, No. 9761. Convention date, April 23, 1931. [Classes 39 (ii), 75 (ii), and 75 (iv).] Mounting reflectors on lamp casings; mounting electric lamps in lanterns.-A hand battery lamp is fitted with a separable head comprising a holder, which may act as a cover or reflector, within which the lamp-bulb is mounted, a spring upon which the holder pivots and a member consisting of two interconnected flexible legs to which the spring is attached. In the form shown in Figs. 1 and 4, the U-shaped member 26 fits in the cup 8 mounted in the top of the casing 2, and is held in position by beads 30 engaging in apertures 16 in the side walls of the cup. The curved spring wire 25, on the ends of which the cover 21 pivots, is clipped at 27, 28, 29 to the U-shaped member 26, at distances from the bottom less than the distances of the point of pivoting from the cam-like ends 22 on the cover, so that the cover is always pressed downwardly and will therefore snap into either the open or the closed position. Thumb pads 31 on the U-shaped member register with cut-out parts 17 in the cup 8 and casing 2, and are compressed when the separable head is to be removed. When the cover 21 is in the closed position, removal of the separable head is prevented by reason of the fact that the legs of the U-shaped member 26 cannot be pressed inwardly owing to engagement by the cams 22 which are bent outwardly where they join the cover. In modified forms, spring members other than spring wire may be used, or the U-shaped member and springs may be made of one piece, e.g. by stamping from flat spring material. A modified form of member with flexible legs, shown in Fig. 5, comprises a bottom plate 33 to which the wire is attached 'at 39, 40 and sides 35 which are compressible inwardly and have projections 36 which engage in apertures in the cup 8. Flanges 38 on the sides 35 give some rigidity to the latter. The cells and electrical contacts are arranged as described in Specifications 298,531, 331,781, [both in Class 39 (ii), Electric lamps, Incandescent], and 354,415, [Group XXXVI].

Abstract: 1,220,991. Refrigerating. BERTIN & CIE. 29 Feb., 1968 [1 March, 1967], No. 9860/68. Heading F4H. Refrigeration apparatus comprises a pure fluid switch in which gas passes alternately into the two outlet conduits, flow into the first outlet conduit producing compression and discharge of initially present gas, and flow into the other outlet conduit causing expansion and entrainment of fluid from the first conduit. As shown in Fig. 3, the first outlet conduit 44 includes a spring-loaded valve 48 controlling an outlet opening 47 and a check-valve 71 which opens to permit flow through an inlet opening 53 when the pressure in conduit 44 falls sufficiently. A pulsed gas supply is fed to the switch inlet 43 and each pulse is directed preferentially to conduit 44 causing compression and discharge of gas initially present. As the pressure increases flow switches to conduit 45 to produce a suction effect which results in expansion of the gas in conduit 44 and its entrainment by the driving gas. The relatively cool mixture then discharges through conduit 45 and valve 71 opens to charge conduit 44 for the next pulse. Two such switches may be fed by a multivibrator (Fig. 4, not shown) or the switch is modified as in Fig. 7 to operate with a constant gas supply. Switching is effected by providing a feedback path comprising restricted conduits 59, 61 and a capacitance 60. In this embodiment valve 48 is replaced by two fluid diodes 62, 63 and valve 71 by fluid diode 64. The devices may be staged (Fig. 8, not shown), each stage comprising a pair of switches and a multivibrator. The cool gas from each pair of switches is merged and used to pre-cool the gas fed to the multivibrator of the next stage and to supply the make-up gas for the first conduits of the switches of the next stage. From the third stage onwards, the relatively warm gas discharged from the switches may be used for pre-cooling in the previous stage.
