Patent GB-2174212-A (GB)
Title: Optical switch
Inventor: SCARR ROBERT WALTER ALISTER
IPC: G02F1/313
Filed: 1985-04-27
Abstract: An optical waveguide switch has a thin guiding layer (N1) flanked by regions (N2, N3) of controllable refractive index material which are themselves flanked by outer guiding layers (N4, N4). To switch a light beam from the central layer (N1) to one of the outer layers (N4), the refractive index of the appropriate controllable index layer N2 or N3) is adjusted, e.g. by applying a suitable electrical potential to it. This causes the light beam to be bent out of the central layer to the outer layer. The material of the layers can be GaAs for the central layers, the controllable index layers can be Ga1-xAlxAs, and the outer layers may also be GaAs. The switch may be formed as a mesa structure, or by diffusion into a material formed on a substrate. <IMAGE>

Title: Catalytic production of methane
Inventor: BUTLER DR GRAHAM
IPC: C07C1/00
Filed: 1985-06-10
Abstract: Methane is produced by reacting CO or CO2 with hydrogen in the presence of a catalyst in a so-called 'methanation' reaction. To mitigate problems of poisoning and/or ageing of catalytically active material, the catalyst is in the form of one or more discrete catalyst bodies, the or each body having a plurality of internal pathways of pre-determined dimensions and arrangement for reactant(s) and/or product(s) of the reaction and containing the catalytically active material for the reaction uniformly and homogeneously dispersed therethrough. The material may constitute more than 50% by weight and even substantially all of the or each body. The catalytically active material may, for example, be NiO/NiAl2O4.

Title: Surgical clip applying apparatus
Inventor: GREEN DAVID T
IPC: A61B17/128
Filed: 1985-12-20
Abstract: Surgical clip applying apparatus operable entirely by one hand for advancing clips one at a time into a pair of jaws which close the clip on body tissue. The clips are fed to the jaws in a line. The clips releasably intercouple with one another to form a train which is advanced by a clip pusher acting on the distal-most clip in the train. As the distal-most clip enters the jaws, it is uncoupled from the clip train, and the jaws then close the clip. The pusher is then retracted behind the next clip in the train to ready the apparatus for another cycle of operation.

Patent GB-2201995-A (GB)
Title: Locks
Inventor: WORRALL RAYMOND
IPC: E05B63/00
Filed: 1988-03-09
Abstract: The throwing mechanism of a cylinder mortice lock is adapted to achieve an increased length of throw for a given cam radius. To this end the drive slot 10, instead of being cut directly in the bolt tail, is provided in a separate drive member 9 pinned to the bolt at 11 and constrained to move along an arcuate track 14. The drive member 9 therefore serves effectively to amplify the movement of the cylinder cam 16 with respect to the bolt 3. As the drive member 9 rocks around the cylinder 15 as the bolt is extended and retracted it is also possible to include extended flank angles on the drive member without fouling the cylinder. <IMAGE>

Title: Brain-wave-controlled computer interface
Inventor: EDWARDS BRIAN
IPC: G06F3/01
Filed: 1988-06-17
Abstract: A Brain Wave Controlled Computer interface enables an individual to communicate messages to a computer by means of that individual's cerebral electrical activity. It usually comprises amplifier and filtering stage 1, a filter stage 2, comprised of N substages respectively tuned to suitable frequencies, an analogue to digital conversion stage 3, which can be comprised of N substages, and where appropriate an output and buffering stage 4. The system user deliberately controls the electrical activity in his or her brain in a manner that can be detected by the interface. This is a learned ability acquired through practice with appropriate bio-feedback aids. In essence the cerebral electrical activity is varied in relative intensity at appropriate frequencies by the system user and these frequency signals are converted into a digital form that can be read by a computer or microprocessor based device. <IMAGE>

Title: Fabric decatising machine
Inventor: MORRIS SYDNEY PARNELL
IPC: D06C7/00
Filed: 1989-06-28
Abstract: A continuous decatising machine has a heated roller 12 and a cooling roller 14 around which two endless blankets 18, 20 extend to enable a fabric 56 which is being decatised to be entrained therebetween so as to subject the fabric fibres to a heating and plasticising treatment and then to a cooling treatment. The fabric 56 is subjected to a compressive loading exerted thereon by the tension of the blankets 18, 20 and to an additional pressure exerted thereon by the nip defining heating and cooling rollers 12, 14 as the fabric 56 entrained in the blankets 18, 20 passes therebetween to produce a set in the fabric fibres which are then subjected to a thermal shock during passage around the cooling roller 14 to retain the fabric fibres in their set condition. The nip pressure increases the degree of setting of the fabric fibres. The tension on blankets 18, 20 is adjustable. The roller 12 uses steam and compressed air and roller 14 is cooled by suction. The fabric may pass through additional cooling or refrigeration unit.   <IMAGE>

Title: Pretreatment primer for metal substrates
Inventor: CASPER JAMES WILLIAM
IPC: C08L75/04
Filed: 1989-11-06
Abstract: A primer for application to metal substrates particularly as part of a coil coating process uses, as a vehicle, an aqueous acrylic polymer dispersion containing a reactive steric stabiliser, thereby allowing the incorporation of oxidising acids, especially chromic acid, without destabilising the dispersion. Epoxy resins and crosslinking resins may also be intimately incorporated in the polymer particles. The primer also includes opacifying and optionally anticorrosive pigments. Use of the primer avoids the need for a pretreatment stage in the coating process.
