Abstract: An adaptor for mounting a reel of filamentary material on a shaft comprises radially inner and outer wire rings 10, 12, respectively spaced axially apart by support wires 16, 14, arranged circumferentially around the radially outer rings. Locking plates 18, 22 are provided at each axial end of the adaptor whereby it may be inserted in the bore of the reel in an axial direction and then limitedly rotated relative to the reel to lock the reel on the adaptor against axial movement. The reel is composed of a pair of wire rings 24 joined by U- shaped wire elements 28, 26, and two such elements 26 enter slots 20 in plates 18 during axial movement prior to locking. The reel may hold welding wire in a welding machine. <IMAGE>

Title: Tube for telescopical boom
IPC: F16B7/10
Filed: 1980-01-08
Abstract: A tube (28) for mounting between an inboard neighbouring tube (27) and an outboard neighbouring tube (20) in a telescopically extensible and retractable boom has a first catch (22) for securing the tube in a retracted position within the inboard neighbouring tube by engagement of a plunger (24) in catch-plate (25) and a second catch (23) for securing the outboard neighbouring tube in an extended position by engagement of a plunger (38) in a catch-plate (similar to catch-plate 51). During boom extension the first catch is released by substantially full extension of the outboard neighbouring tube by plunger contact with a profiled portion (similar to profiled portion 34). During boom retraction the second catch is released by substantially full retraction of the boom by plunger contact with profiled member (43). By providing first and second catches or each tube of a boom the extension and retraction order of the tubes is defined, avoiding the order uncertainty of prior art tubes. <IMAGE>

Title: Variable diameter transmission wheel
IPC: F16H61/662
Filed: 1980-10-27
Abstract: An automatic variable speed chain transmission includes a variable diameter sprocket including a rotary support (31) carrying six or more radially movable toothed elements (21, 22) etc., whose radial positions are determined by engagement of their spindles (33) with co-operating spiral grooves (35) in another rotary plate (32). At least some of the toothed elements are rotated through different angles, and some in different directions, by rack and pinion means (37, 36), to ensure proper alignment with the teeth of the chain for all different effective diameters of the sprocket. A spring (41) acting between the rotary discs (31, 32) provides automatic adjustment of the sprocket diameter and hence the gear ratio. Instead of guiding the individual toothed elements in radial slots they may be mounted on tangential pivoted links (52, 53). <IMAGE>

Title: Multi-function automobile electrical switch
Inventor: PRAS JEAN-CLAUDE
IPC: B60Q1/14
Filed: 1983-01-25
Abstract: A multi-function electrical switch for controlling the external lighting on a motor vehicle, comprises a control lever 50 having a drive cam shaft 7 rotationally coupled thereto and a driven cam shaft 8 rotationally coupled to shaft 7 by a lost motion device allowing limited relative rotation of shafts 7 and 8. Shafts 7 and 8 include cams whereby rotation of the lever about its longitudinal axis closes electrical contacts to operate lights, and also further cams to operate additional lights upon pivoting of the control level. The pivoting causes rotation of shaft 8 relative to shaft 7 to operate the additional light via contacts, and a further cam is provided to cause reverse turning of the shaft 8 relative to shaft 7 when the level is returned from a third to a second angular position. In one angular position of the lever 50, contacts are opened and closed by successive pivoting movements of the lever 50. The lever 50 also operates direction indicators and is rectilinearly movable to actuate switch contacts for operating a horn. <IMAGE>
Patent GB-2117451-A (GB)
Title: Gas turbine shroud
Inventor: PASK GEORGE
IPC: F01D11/08
Filed: 1983-02-10
Abstract: The shroud 15 comprises segments 25 retained to support structure in the form of a carrier ring 29 consisting of an alloy which retains high strength at high temperatures, cooling air chambers 53 being defined between the segments 25, strengthening ribs on the segments and throttle plates 58 which also form part of the high strength support structure for the segments. Cooling air from chamber 49 is metered into shroud chambers 53 through holes 57 in throttle plates 58 so that the pressure in chambers 53 is only just enough to ensure exhaustion of the cooling air through holes 55 into the turbine passage just downstream of the rotor blades 7. This ensures not only low consumption of cooling air but also that the shroud segments are thrust outwards against their seatings on the throttle plates 58 by the higher turbine gas pressures upstream, the strengthening ribs defining load paths which give the segments 25 adequate distributed support to prevent overstressing. The segments may be of a highly oxidation resistant alloy, e.g. FeCrA l Y or MCrA l Y. <IMAGE>
