IPC: A47C4/02
Filed: 1966-09-26
Abstract: 1,206,587. Seats. A. C. REVELL. 21 Dec., 1967 [26 Sept., 1966], No. 42943/66. Heading A4J. In the knockdown chair, the assembly of the seat 13 and backrest 14, with the side portions 55, 56, is completed by wedging together resilient tongues 30 of opposed pairs of releasable fasteners, arranged on either side of the chair. The hinge connections 60, 59 between leg frames 50 and the seat and backrest can be permanent or, as in the case of a hinge connection between members 52 and 55, hinges 60 can be made detachable. Instead of hinges 59, 60 and leg frames 50, the side portions may be formed as chair supports (11, 12, Figs 1-3, not shown). Releasable pivotal connections (24-28, 25-33) may be formed by key-hole or L-shaped slots and in a form constructed from Cd plated tubular steel, with T-shaped slots. In order to assemble multiple seating, a modified side portion is made without an armrest (23) and with connections (24, 25 and) 30 on both sides, so that it can interconnect adjacent seats 13 and backrests 14.

Abstract: 1,147,114. Heat-treating filaments. FARBWERKE HOECHST A.G. 25 Sept., 1967 [23 Sept., 1966], No. 43552/67. Heading B5B A tow of filaments of a synthetic polymer is passed through a treatment zone in which the tow is supported by an upward current of a hot gas, the tow extending freely between supply and withdrawal means and the rate of supply and withdrawal being such, in relation to the temperature of the hot gas, that the filaments undergo thermal shrinkage in substantially tensionless condition. The gas may be air, steam or nitrogen, and suitably has a velocity of 0À2-6 m./sec., to support a tow of filaments of density 1000-30,000 denier/cm. The gas is suitably passed to the tow through a perforated plate, lattice or fabric. Examples show the treatment of polyethylene terephthate; polyolefines, polyamides and polyacrylonitrile are also specified. Suitable apparatus is illustrated (Fig. 1, not shown) wherein hot air is recycled in a closed system through a glass-fibre fabric on to a moving tow of filaments passing through a horizontal passageway.

Title: Actuator device for use in a gas turbine engine
IPC: F02C9/00
Filed: 1972-10-03
Abstract: 1438767 Clutch control LUCAS INDUSTRIES Ltd 30 Oct 1973 [3 Oct 1972] 45455/72 Heading F2L [Also in Division F1] An actuator device for use in the control of a gas turbine engine fuel supply in an aircraft comprises an output shaft 13 coaxial with an input worm-wheel 14 (driven by a motor through a worm 16) and a manual input shaft 15, the output shaft 13 having a plate 18 fixed to it which pivotally mounts a pawl member 19 spring biased to cause the pawl 19 to engage the teeth of the worm-wheel 14 and connect together input wheel 14 and output shaft 13, and the input shaft 15 having an arm 20 which mounts a pawl member 21 which can engage a notch 18b (not shown) in the plate 18 to connect shaft 15 and output shaft 13 together and simultaneously pivot pawl member 19 through engagement with an extension 19a to disengage wheel 14 from the output member 13. The pawl member 21 supports a roller 22 which runs on a cam track 23 fixed to the body of the actuator, the cam track defining a region in which engagement of pawl 21 and notch 18b is possible (an automatic control region) and a region in which it is possible (manual control). Disengagement of shafts 15 and 13 and re-engagement of wheel 14 and shaft 13 can be accomplished either by movement back of shaft 15, which in the application to an aircraft engine causes the engine to idle as a lever 31 interlinked to a lever 30 which rotates shaft 15 is moved back, or by movement in the opposite sense (past the full speed position) which causes the arm 20 of shaft 15 to strike an abutment 24 which pivots the cam 23 to disengage pawl 21 and allow pawl 19 to re-engage. A pawl 25 linked to cam 23 as shown pivots the cam 23 back on being struck by arm 20 as the shaft 15 (i.e. lever 31) is moved back from its full speed position. The disengagement of manual control 31 from the output shaft 13 can thus occur at either full speed or idle. As shown in Fig. 2 the rotation of worm 16 is controlled by a computer 33 receiving inputs from the engine 34, a transducer 29 responsive to the position of an arm 27 connected to shaft 13 and the position of control lever 31, the output shaft 13 controlling a fuel valve 35 through arm 27.

Abstract: 1500238 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 3 Nov 1976 [18 Dec 1975] 45667/76 Heading H1K A masking layer for use in semi-conductor device manufacture, e.g. to localize a diffusion, etching or isolation process, comprises a first layer 2 of silicon dioxide covered by a second layer 3 of carbon-containing silicon nitride. The low intrinsic tensile stress of layer 3 reduces the deleterious effect on the underlying crystal perfection of conventional silicon nitride masking layers. The layer 2 is formed by thermal oxidation or gas phase deposition, while the layer 3 may be deposited from a gaseous mixture comprising silicon nitride (formed by the gas phase reaction of ammonia or a volatile amine with a volatile silane such as silane, halogensilane, alkylsilane or arylsilane) and a gaseous hydrocarbon such as methane, ethane, propane, butane, ethylene, propylene, butylene or isobutylene, preferably in a carrier gas. During deposition of the layer 3 the substrate 1 is heated to 600-1000 C.

Title: Photographic apparatus

Filed: 1962-12-03
Abstract: 1, 020, 593. Photographic processing apparatus. ITEX CORPORATION. Dec. 3, 1962 [Dec. 1, 1961], No. 45689/62. Heading G2A. The communicating means between a storage container for processing liquid and the processing tank in which it is used has a valve which automatically shuts off the flow of liquid from container to tank when the liquid level in the latter reaches a predetermined level. In the form shown, two tanks 11 are provided (only one visible) for sequential treatment of photographic material. Each tank has a dished bottom, connected by an elbow 12 to a flexible tube 84 leading to the supply container. This comprises two square-section plastic bottles, as at 104, one for each tank, mounted in a metal bin 24. This is shown in the raised (operative) position in Fig. 1, the dotted lines indicating the lowered (inoperative) position. The bin has a cover 60, which is hinged to a support frame 13 by the same hinge as the body part of the bin 24, although the two can be raised or lowered independently. Secured to a panel at the back of the bin is a plastic block 76 having a wide bore 78 communicating with another bore 80 at rightangles. The mouth of bore 80 is fitted with a compressible gasket 81, and the neck of each plastic bottle can engage against and form a liquid-tight seal with the corresponding gasket 81 when in the raised position. A bar 88 is pivoted at one end to a bracket fixed on frame 13, and a pin at its other end slides in a slot formed in part of the bin structure. Another bar 95 is pivoted at one end to a bracket fixed to the cover 60, and also has a pin at its other end sliding in a slot formed in another part of the bin. Initially, to load the apparatus, the bin 24 is lowered, as shown in Fig. 2, and the cover 60 raised to the position shown in dotted lines. After the two bottles of processing liquid (e.g. developing and fixing solutions) have been placed in position, the cover is closed and fastened shut. In this position, the gaskets 81 engage the necks of the bottles. The bin is now raised to bring the bottles into the operative position. Liquid flows from the bottle 104 through the bore 80 and nipple 82 into the tube 84, and so into the tank 11, until the liquid level L is such that it closes off the opening from bore 78 into bottle 104. Thus no more liquid can flow in from bottle 104, even though the liquid level in the bottle is higher than L. As the liquid in the tank is used up or evaporates, the level L falls until air can once more pass through bore 78 and bore 80 into bottle 104, thus enabling more liquid to flow into the tank. In this way the liquid level L is maintained. When the tank is not in use, or to remove sediment, the liquid may be run back into the bottle by lowering the bin into the inoperative position. The arrangement of sliding rods 88, 95 prevents incorrect use, e.g. raising the bin before the cover is closed.
