Patent GB-840046-A (GB)
Abstract: 840,046. Electrolytic capacitors. WESTERN ELECTRIC CO. Inc. Aug. 23, 1957 [Sept. 14, 1956], No. 26695/57. Class 37. An electrolytic capacitor or rectifier comprises a plurality of electrodes 11, 12 one of which 12 is coated with an oxide film; and an electrolyte of lithium or calcium chloride to which is added an amount of boric acid capable of maintaining a desired acidity condition of the electrolyte. As described, an electrolytic capacitor comprises a silver cup cathode 11 and a porous tantalum anode 12 coated with a tantalum oxide film. The anode is attached to a tantalum disc 13 insulated from the cathode by a polytetrafluorethylene ring 15 and a rubber or plastic seal 16. The electrolyte comprises 8N-10N lithium chloride or 2N- 5N calcium chloride together with not more than 5 gms. boric acid per 100 millilitres. The acid maintains the pH of the electrolyte below 8 thus protecting the anode film from attack by alkaline products which are formed as the capacitor ages by a variety of causes, some of which are described. Polar solvents other than water may be used for the electrolyte. Both electrodes may be of oxide coated porous tantalum.

Title: Sound activated light switch
Inventor: NORTHCOTT CHRISTOPHER PAUL
IPC: H05B37/02
Filed: 1984-07-04
Abstract: A sound activated light switch, installs in place of the present house light switch, has a circuit that will automatically turn the lights on when a sound is heard. The sensitivity of the sound can be adjusted giving various volumes of noise to operate the switch. When a sound turns the lights on, an internal clock starts counting, each time a new sound is heard, the clock starts back at zero. The internal clock can be adjusted to give various lengths of time for the lights to stay on in the absence of sound. A manual on, off and dimmer knob, when used as the dimmer will put the switch in the sound activated position. In addition, a light sensor is incorporated in the circuit to reduce the sensitivity to sound in daylight.

Title: Attacking targets with submunitions
Inventor: STESSEN LOTHAR
IPC: F42C13/00
Filed: 1984-08-03
Abstract: It is desired to reduce the attack range 15 and minimise the scatter radius 14 when attacking target objects 4 by means of submunitions 2 which discharge projectile-forming liners from hollow charges or eject clusters of small munition articles upon target acquisition by sensor 6. Accordingly, when the submunition 2, simultaneously rotating and descending, detects a target 4 for the first time at a relatively great height H, transverse motion 17 is superimposed on the descent motion 16, whereby the submunition approaches along an inclined glide path 19. The transverse motion 17 may be dependent upon the original acquisition height H. Circuitry is provided whereby the sensor 6, upon acquiring a target, is switched off and a propulsion mechanism, e.g. an impulse charge or a segmented braking parachute, is operated to cause the shift 17. The sensor is switched on again after a steadying vertical motion 16.1, and a trigger is set so that detonation occurs when the target is again acquired by the sensor. <IMAGE>

Title: Intumescent fire retardant composition
Inventor: PALMER THOMAS WILLIAM
IPC: C08L63/00
Filed: 1986-01-24
Abstract: A fire retardant material comprises an intumescent fire retardant, such as a two component fire retardant epoxy resin, and a plurality of undulating spheroids. The spheroids may occupy about 50% by volume of the layer. A second layer comprising fire retardant epoxy resin may be applied over a first layer. The inclusion of spheroids in the fire retardant material substantially increases the time which it takes for the substrate to reach 93 DEG C and hence gives additional time for motor operated safety valves and the like (which become unreliable in operation above 93 DEG C) to function properly.

Title: Method and apparatus for testing the stability of structural glazing sealed onto facade elements
Inventor: GARTNER DR FRITZ
IPC: G01M3/28
Filed: 1986-05-06
Abstract: For testing the stability of structural (frameless) double glazing (12) comprising panes 14, 16 secured together by sealant layers 20, 22 on a peripheral spacer 18, on a facade upright (10) the space (38) enclosed by the facade upright (10), the glazing (12) and the sealing strips (30, 36) holding the glazing on the facade upright is subjected to a gas under pressure. The pressure drop of the gas in the space is determined from time to time so that the quality of the seals (30, 36) can be assessed. Alternatively or additionally the interspace between the panes may be pressurised by means of a valved pipe passing through the peripheral spacer and the integrity of the sealant by securing the panes to the spacer may be determined from time to time in the same manner. In an alternative embodiment for single or double glazing a wall member is sealed to facade elements all round the pane to define between the pane and the wall a space which may be pressurised to enable a leak test to be performed. Instead of measuring the pressure loss with time, neon, metered of air may be inroduced to the space and a probe moved around the seal to be tested to detect escaping gas. <IMAGE>

Abstract: A light fitting for mounting on a ceiling includes one or more tubular lamps (16, 18) carried in a supporting structure (12) which has for the or each respective lamp a first light outlet (52, 54) through which light is emitted generally downwards and a second light outlet (40, 42) around the same level as the lamp through which light is emitted generally horizontally and upwardly for illuminating the ceiling and upper wall areas of a room. Predetermined zones of the room are shielded from light directly from the lamp(s) by longitudinal light obstructing means (26,56,28,58) intermediate the first and second outlets. Louvres (60, 61, 62) and reflectors (46, 50) are used for light output optimisation and directional control. The fitting is particularly useful in hospital wards where the light obstructed zones are arranged to coincide with bed head regions thus preventing glare to patients, and in offices for preventing reflections from VDU screens. <IMAGE>

Title: Black-coloured titanium nitride coatings
Inventor: SHINOMIYA HIDEO
IPC: G04B37/22
Filed: 1986-11-11
Abstract: An improved method for forming an aesthetically beautiful black-coloured surface film of titanium nitride on an ornamental article by the method of ion plating is characterised in that titanium metal is vaporized in an atmosphere of nitrogen containing oxygen and carbon dioxide, each in a small but substantial volume %, under a reduced pressure while a DC voltage of 1 to 450 volts is established between the vaporizing titanium source and the article to be surface-treated. Unlike the golden coloured film of titanium nitride obtained by conventional ion plating, the surface film deposited on the surface has a beautiful grey to black colour with good reproducibility and reliability and finds particular application in personal ornamental articles such as cases and straps of watches, and frames of spectacles. The substrate may be titanium, or brass plated first with nickel and then with an alloy of palladium and nickel.
