Patent GB-2055632-A (GB)
Title: Dusting wires and cables
IPC: B05B7/14
Filed: 1980-07-21
Abstract: Electrical wires and cables (38) are dusted with talc, to prevent the sticking together thereof, by fluidizing the talc in a chamber (12) and conveying talc-laden air from the chamber to a dusting nozzle (30). A fluidized bed of talc is produced by a fan (22) creating an air flow up through a permeable screen (21). A conveying nozzle (24) receives some of the air flow, being positioned close to the screen, and comprises a convergent portion (36) which accelerates the flow of talc- laden air to transport it to a discharge portion (32) of the nozzle. A rotary drum filter (50) [Fig. 2] is provided to separate talc from the air prior to recirculation of the air. The drum is rotated so that filtered talc is thrown from the surface thereof. <IMAGE>

Patent GB-2058360-A (GB)
Title: A measuring sensor for gases
IPC: G01D11/24
Filed: 1980-08-29
Abstract: A measuring sensor for gases comprising at least one wafer-like sensor member (14/1 .. 14/2) with layer-like measuring elements disposed thereon is integrated in a flat seal (10) serving as measuring sensor housing. The flat seal or gasket 10 is disposed between two pipes carrying gas. That end portion of the sensor member which faces the gas to be measured carries the measuring elements which are directly exposed to the gas to be measured. The arrangement enables a measuring sensor to be constructed in an inexpensive manner and frequently enables it to be fitted in those regions of devices, carrying gases to be measured, where there are normally no facilities for installing measuring sensors. The measuring elements may be solid electrolyte sensors, and the members (14/1 ... 14/2) may be elongated or circular. <IMAGE>

Patent GB-2076404-A (GB)
Title: Non-smouldering latex foams
IPC: C08J9/00
Filed: 1981-05-13
Abstract: A non-smouldering foam material is derived from a latex of a butadiene rubber with optionally natural rubber latex by treatment with up to 15 parts by weight per hundred of rubber with either a reclaiming agent or guanidine or a derivative of guanidine. The reclaiming agent, which hastens depolymerisation of rubber, may be a thiol, a disulphide or an aliphatic primary amine. Preferably the guanidine derivative is diphenylguanidine, which can be incorporated into the latex formulation before or after frothing without causing processing problems. Alternatively, the reclaiming agent, guanidine or guanidine derivative can be used in the post-treatment of an already-produced foam. The foams of the present invention pass the "cigarette" test laid down in British Standard Specification No 5852.

Title: Dual-flush cisterns
Inventor: JIUNN CHERNG HUANG
IPC: E03D5/02
Filed: 1981-12-09
Abstract: In a dual-flush cistern a discharge valve (not shown) linked to an L- shaped actuating arm 90 extending from a housing 100 secured to the cistern wall is opened by selectively unlatching upper and lower floats 70, 80 using coaxial flush-initiating handles 10, 20. The floats 70, 80 may be height-adjustable and are coupled to respective pivoted cradle arms 30, 40 latched by depending crank arms 13, 23 coupled to the respective handles. For a partial flush, handle 10 is depressed, so lifting arm 90 and rotating arm 13 to unlatched arm 30; arm 30 is thereupon raised by float 70 and in so doing rotates arm 13 to continue raising arm 90; the discharge valve is thus held open until the float sinks to the original position. For a full flush, handle 20 is depressed so unlatching arm 40 and also unlatching arm 30; both floats now rise to hold the discharge valve open until, as the cistern empties, the float 80 returns to its original position. <IMAGE>

Patent GB-2108394-A (GB)
Title: Flexible intraocular lens
Inventor: BAYERS JON H
IPC: A61F2/16
Filed: 1981-03-20
Abstract: An intraocular lens (10A) for placement in either the anterior chamber (24) or posterior chamber (28) of the eye (14) which employs a lens portion (12) intended for placement adjacent a side of the iris and at least one flexible appendage (76 or 78) extending from the lens portion (12) to the extreme periphery of the iris. To prevent endothelial touch the appendage (76, 78) is formed into a loop having a flattened or oval cross-sectional configuration in which the shorter dimension is oriented substantially normal to the optical axis of the lens (12). In this manner, any force directed at the end portion of the appendage (76, 78) cause it to spread laterally, generally normal to the optical axis of the lens (12) and pupil rather than vertically inwardly or outwardly in relation to the plane of the iris. The restricting flexing of the appendage (76, 78) also allows for variation in ocular sizes thereby reducing the number of precise different sized lenses needed at the time of surgery. The lens structure (10A) with its flexible appendages (76, 78) overcomes many common problems associated with prior intraocular lens such as post operative dislocation either anteriorly or posteriorly within the eye, uveitis, iritis, glaucoma and persisting eye tenderness.

Title: A sensor controlled weapon
Inventor: KOETSER HARRY
IPC: F42C13/02
Filed: 1982-11-18
Abstract: An array of infra-red detectors 8 are illuminated by an image of a field of view containing a potential target. The number of sensors illuminated by the target is indicative of its apparent size. An altimeter 11 controls a logic circuit 10 so as to detonate the weapon in respond to the illumination of different selections of sensors for different altitudes. In this way the weapon is made sensitive to targets of apparently larger size at low altitudes than at high altitudes since at high altitudes targets appear to be relatively small the weapon is in fact made to respond to targets of constant real size whatever its altitude.
