Patent GB-2024912-A (GB)
Title: Adjustable rope gripper
IPC: A62B1/14
Filed: 1978-07-04
Abstract: A device for use in descending a rope 27, comprises a friction grip which can be fitted on to the rope at any point along the length of the rope without the need to thread the rope through the device. Downward load applied to the device, causes the device to lock on to the rope and prevent descent. The device has a control lever 15 which can be pulled down to reduce friction thereby bringing about a controlled descent. If the control member is released again, the device locks on to the rope and prevents further descent. <IMAGE>

Title: Radio-frequency heating installations
IPC: H05B6/50
Filed: 1978-07-20
Abstract: A radio-frequency energy heater (12) in which RF energy is applied across a heating zone to heat a dielectric material includes a detector (18), constituted by a neon or fluorescent tube, responsive to stray RF energy located outside the zone, and a responder (19) coupled to the detector for signalling a reduction in stray RF energy to switch off or reduce the RF energy supply to the heating zone in response to said reduction in stray RF energy. This has the effect of cutting off the RF energy in the heating zone if arcing occurs therein and hence reducing the likelihood of fires. These heaters can be used for curing resin impregnated filter papers (17). <IMAGE>

Title: Method and apparatus for producing a foam from a viscous liquid
IPC: B05B7/26
Filed: 1979-10-29
Abstract: A method and apparatus for producing a coherent output stream of viscous liquid containing a foam- forming dispersed gas. The liquid is pressurized and delivered to apparatus having an internal chamber 50 which presents a flow space for the flow of the liquid through it as an integral stream.

Title: Electrochromic cells
IPC: G02F1/1516
Filed: 1980-11-19
Abstract: In a typical electrochromic cell comprising a main electrode layer 2, 3 on a non-conductive substrate 1 and bearing a layer 4 of electrochromic material, and a counter electrode 6, the electrodes being separated by electrolyte 5, two particular problems are the poor adhesion of the electrochromic layer to the main electrode layer, and the poor quality of the colour generated. Both are alleviated by the use of holmium diphthalocyanine as the electrochromic material, and by forming the main electrode layer as a layer 2 of vitreous tin oxide overlaid by bismuth or antimony oxide 3. The preparation of holmium phthalocyanine is described. <IMAGE>
