Patent GB-2064232-A (GB)
Title: Improvements in and relating to electrical connectors
IPC: H01R13/595
Filed: 1979-11-26
Abstract: An electrical connector characterised by a deflectable cable clamp integral with the body of the connector.

Title: Woven Sliding Clasp Fastener Tape and its Manufacture
IPC: D03D1/00
Filed: 1981-02-16
Abstract: A stringer tape is woven with spaced zones in the tape of 1 and 1 weave separated by an intermediate zone of 2 and 2 weave which spans a path where sewing will take place. Warp threads in the spaced zones have a greater contractability than warp threads in the intermediate zone which consequently has a more relaxed construction than the spaced zones. The relaxed construction of the intermediate zone permits its contraction during the sewing operation without producing undesirable humps or undulations in the fastener and associated article. <IMAGE>

Title: A gettering composition and structure
IPC: B22F1/00
Filed: 1981-06-01
Abstract: A gettering composition comprises at least a first non-evaporable getter metal chosen from the group consisting of titanium and zirconium in the form of only partially sintered particles, mixed with a particulate Zr-V-Fe alloy having a particle size greater than that of the first getter metal. The Zr-V-Fe alloy has a composition in weight percent which lies within the polygon shown in Figure 13 having the corner points designated a, b and c. Particle sizes are specified and in the final getter structure the Zr or Ti particles are in contact with one another while the particles of the ternary alloy are generally spaced out of contact with one another. The getter may be activated by heating to 300 DEG  - 600 DEG C for 1-30 minutes. Getter devices using such a composition, held by a container or in general by a support which can be a conducting wire heater, are particularly useful in those applications which require low temperatures and the available space is limited. A method is also described for the manufacture of vacuum vessels and rare gas filled vessels, e.g. C.R.T.'s valves, lamps, T.W.T.'s and klystrons. <IMAGE>

Title: Gasification System
IPC: C10J3/14
Filed: 1981-11-17
Abstract: In a gasification system, primarily for biomass, a feedstock is gasified in a reactor fed with gas from an hot gas generator. The gas inlet to the reactor (4) is supplemented with CO2 which may be fed direct to the generator (6) or to a burner (30) which is part of the generator (6). The CO2 in the gas can enhance the gasification efficiency by carbon fixation. The invention also contemplates various recycling means for the gaseous reaction product from the reactor (4) which permit control of the reaction and nature of the product. Such recycling can be from immediately downstream of the reaction (4), or from a downstream treatment stage (14,18) in which the gaseous product is cleaned. Such cleaned gas can for example be used to fire the burner (30). <IMAGE>

Title: Internal-shoe drum brake for motor vehicles
Inventor: RUPPRECHT KURT
IPC: F16D65/52
Filed: 1982-09-30
Abstract: The brake has a handbrake level (5) rotatably linked to brake shoe (4, 4.1) and an automatic mechanical clearance adjustment device with a strut arrangement (1, 2) extending between the two brake shoes (3, 3.1; 4, 4.1) the effective length of which is automatically increased as soon as the brake shoes move apart by more than a specified clearance S* as a result of wear on the linings or as a result of thermally induced expansion of the brake drum. The brake shoe (3, 3.1) and the brake lever (5) each rest against stop devices of the strut arrangement through the action of return springs when the brake is not in use; at least one of these stop devices, as shown the device (12) which supports lever (5) is constructed to yield to a limited extent until it contacts a stop (132) on strut arrangement (1, 2) so that binding of the brake is avoided if the adjustment device extends the effective length of the strut arrangement (1, 2) after previous thermally induced expansion of the drum even though there has been no wear on the linings. Alternative forms of the yielding device are envisaged. <IMAGE>
