Title: Door hinges
IPC: E05F1/12
Filed: 1979-02-16
Abstract: A door hinge comprises a plate (10) adapted for attachment to a door surround, a leaf (13) at one side of said plate (10) connected by first and second hinge connections to said part and a member (18) adapted to be connected to a door respectively, and a roller chain (26) connected at one of its ends to the member (18) and extending through said plate (10) to the other side thereof, where a compression spring (35) is disposed. The spring (35) bears against a boss (36) at the other end of the roller chain (26) to bias the chain to its rest position corresponding to a closed position of the door. On opening the door, the roller chain is moved to compress the spring (35) and is guided by one of a pair of rollers (28, 29) in a boss fixed to the plate (10). On release of the door, the spring returns the chain to its rest position thereby closing the door. <IMAGE>

Patent GB-2025084-A (GB)
Title: Terminating optical fibres
IPC: G02B6/38
Filed: 1979-06-15
Abstract: A method of terminating an optical fibre cable wherein an annular deformable member (1) is compressed inwardly onto a cable (7) threaded through it by causing an encircling cincture (3) exhibiting 'memory' properties to try to return to a remembered shape and size. The cincture is preferably a brass- aluminium or titanium-nickel alloy which is cooled to below its critical temperature and mechanically expanded. It is then placed on an annular glass ferrule 1 in which the optical fibres 7 have been inserted on heating above its critical temperature the cincture tries to return to its original size and exerts a compressive force on the ferrule, which, on heating flows and is compressed, squeezing the fibres together. The ferrule can comprise sections connected by a heat deformable material. The method can also be used for terminating a single fibre. <IMAGE>

Title: Supplying vehicle road lights and window wipers
IPC: B60Q1/14
Filed: 1979-12-07
Abstract: A motor vehicle has electrical circuitry such that road lights are illuminated when the window wiper is used. An output terminal (10b) of a road light switch (10) connected for delivering power to headlights (6, 7) is connected also, via a diode (8), to an output terminal (3b) of a switch (3) which supplies power to a wiper motor (5), so that when power is supplied to the wiper motor through the switch (3) power is also supplied through the switch (3), diode (8) and terminal (10b) to the main or dipped headlights. The diode (8) prevents operations of the wiper motor (5) when power is supplied to the headlights through the switch (10). The circuit may also be arranged so that energising the wipers at a slow rate turns on sidelights, while use of the wipers at a fast rate turns on the headlights. <IMAGE>

Title: Electronic timepieces
IPC: G04G13/02
Filed: 1980-02-06
Abstract: A single external stem member of an electronic timepiece operates independent switches by push-pull motions and by a rotary operation. Many functions are controlled or adjusted with signals generated by particular sequential combinations of stem member operations in the push-pull and rotary modes. In an alarm timepiece, the rotary switch controls the alarm time setting, and the push-pull switch determines whether an audible alarm and hour markers are to sound, no sounds are to be emitted, or only the alarm is to sound.

Title: Gas turbine shroud ring
Inventor: SADLER JOHN HENRY ROY
IPC: F01D11/18
Filed: 1980-10-03
Abstract: A shroud ring (28) suitable for the turbine of a gas turbine engine comprises an annular heat pipe (27) with radially inwardly directed flanges (28) which are bridged by a plurality of abutting tiles (30) so that together they define an annular chamber (33).

Patent GB-2060713-A (GB)
Title: Treating fabric articles with solvents
IPC: D06F43/08
Filed: 1980-10-10
Abstract: Articles such as clothes are treated using a solvent medium having a high boiling point. The solvent present in the articles at the end of the treatment is recovered by using a fan (5) to circulate an air stream which traverses these articles in a basket (1). The air stream is charged with solvent by the articles and then passes through a cooling unit in order to condense the solvent. The air is circulated in a closed circuit and, upon leaving the basket (1) passes successively through an evaporator (3) and a condenser (4) of a refrigerator which comprises, in the high pressure part of the refrigerant circuit downstream of the compressor (7), an auxiliary condenser (12) supplied with water or air. The operation is carried out in two phases with a first phase in which the auxiliary condenser (12) is not supplied with air or water and a second phase in which the auxiliary condenser (12) is supplied with air or water in such a way that the drop in the temperature of the air entering the basket (1) during the said second phase is of the order of at least 10 DEG C to 30 DEG C. <IMAGE>

Title: Electric batteries, accumulators and generators with non-metallic or solution electrodes
IPC: H01M8/18
Filed: 1979-07-11
Abstract: Batteries, accumulators or electrochemical generators of electric energy, the negative electrode (anode) of which consists of at least one alkaline halide, in aqueous or alkaline solution, or of one metallic halide, and one auxiliary electrode collecting current. The positive electrode (cathode) consists of at least one metallic hydroxide or oxide which can be in solution in the electrolyte and which, preactivated or regenerated continuously by the presence of air or oxygen introduced into the alkaline solution bathing the cathode, supplies the hydroxyl ions necessary for the oxidation of the halide constituting the anode.

Patent GB-2077828-A (GB)
Title: Blind with vertical laths
IPC: E06B9/36
Filed: 1981-04-02
Abstract: A blind has vertical laths hanging from sliders (2) shiftable along a horizontal bearer member (1). The sliders are flexibly interconnected by a tape 3 in such a manner that each slider will pull along the adjacent slider in one sense, or push back the adjacent slider when moved in the other sense. Each slider incorporates a rotatable convex circular disc (21) resting on the two parallel flights of a drawer card, which card is secured to a master slider. A slight pull on the cord causes sufficient differential movements of the flights to rotate the discs and turn the laths, whereby the angles of the laths are adjusted. A stronger pull shifts the master slider, (and thereafter the other sliders) along the bearer member. The master slider can initiate progressive tilting of all sliders to facilitate packing together (Fig. 1, not shown). <IMAGE>

Title: Slewing device, especially for excavating implement
IPC: E02F3/38
Filed: 1981-05-06
Abstract: A slewing system for an excavating implement (6) has, in addition to two symmetrically arranged lateral pivot cylinders (8, 9), an additional pivot cylinder (16) located in a plane of symmetry therebetween and lying on a different level from the lateral cylinders (8, 9) and the pivot shaft (5) of the excavating implement (6). The centre cylinder (16) is jointed to a point of attachment (19) on the excavating implement (6) located on its centre line. The lever arm of the centre cylinder (16) about the axis of rotation (5) of the implement (6) is thus zero when the implement is in its centre position (as shown) and increases with increasing slewing angle. When the implement is swung out 90 DEG , the centre cylinder (16) has a maximum slewing effect. Flow limitors (33, 35) in the feeder lines (31, 32) of the centre cylinder, cause the centre cylinder to be used at the same time as a brake for automatically reducing the speed of slewing as the excavating implement approaches its end positions. <IMAGE>
