Title: Improvements relating to discs for disc brakes
Inventor: WATSON JOHN CAMPBELL
IPC: F16D65/12
Filed: 1986-02-05
Abstract: A disc for a disc brake, comprises two annular members (1,3) arranged coaxially with respect to each other and joined together by generally radially extending vanes (7) and pillars (9), which project from a central web (5) located between the annular members (1,3). The vanes (7) extend for part of the radial extent of the annular members (1,3), and the pillars (9) are located in a region not occupied by the vanes (7) and preferably radially beyond the vanes (7). Power absorption and noise generation is reduced considerably as a result of the reduced vane overall diameter, as compared to a disc of like diameter with the conventional long radial vanes. However, the desired cooling is maintained due to the surface area presented by the combination of shorter vanes (7) and pillar (9).

Title: Universal bearing
Inventor: COWAN GEORGE NICHOLLSON
IPC: F16D3/16
Filed: 1986-03-12
Abstract: A universal bearing for providing rotational drive between a drive member (20) and a driven member (1), allowing tilting movement of the driven member (1) relative to the driving member (20), comprises a ball bearing (7) pinned to the driven member (1), and a part-spherical seating (7A) disposed in the driving member (20). The seating (7A) is urged resiliently towards the ball bearing (7), preferably by means of a compression spring (13). Rotary drive is transmitted by a plurality of elongate bearings (11) mounted peripherally of the ball bearing (7) for reciprocating axial sliding movement in corresponding sockets in the driving member (20). The bearing may constitute a slip clutch, whose torque setting depends on the resilient bias of the elongate bearings (11) towards the driven member (1).

Patent GB-2194131-A (GB)
Title: Swimming aid
Inventor: MCHUTCHISON CHARLES
IPC: B63C9/135
Filed: 1987-08-20
Abstract: An improved non-inflatable swimming aid (10) is described which is particularly suited in assisting children and the disabled on learning to swim. The swimming aid (10) includes a buoyant belt (12) with a nylon strap (14) which can be fastened around a childs waist by Velcro fasteners (20,22) and which has separate handles (18) attached to the belt for gripping by a swimming teacher. In use, the belt permits freedom of movement of the users arms and legs and also, at the same time, ensures an adequate degree of supervision of the child because the teacher has to hold the belt. Moreover, the swimming aid belt is made of a non-inflatable closed cell PVC foam so that buoyancy is retained and this provides additional confidence to the child. <IMAGE>
Patent GB-2209008-A (GB)
Title: Positive feed drill with feed control
Inventor: SILK GEORGE ROBERT
IPC: B23Q5/40
Filed: 1987-08-27
Abstract: The drill (10) has a rotatably driven shaft assembly comprising shafts (24, 82) having a splined connection (80). The shaft (82) is axially movable by engagement with an externally threaded feed drive shaft (56) which is rotatable with, and axially slidable upon a feed drive shaft (54). A feed engagement mechanism (20) comprises a housing (92) and a partly rotatable cam plate (104). Three part nuts (112) are mounted on pins (108) each of which is located in a respective slot in the cam plate. Each part nut is also mounted in a radial opening in an inner annulus of the housing (92). The rotation of the cam plate (104) by means of a feed handle causes the part nuts (112) to move radially, inwardly and outwardly through the openings to engage or disengage the part nuts with the external thread of the shaft (56). The engagement of the part nuts with the external thread on shaft (56) causes the shaft (56) to move axially and thereby causing the drill shaft (82) via a thrust bearing (88) to move axially on the spine connection (80). <IMAGE>

Title: The manufacture of lightweight extruded structural profile
Inventor: HEWITT MICHAEL JOHN
IPC: B29C48/07
Filed: 1988-04-11
Abstract: In the manufacture of the profile comprising a resin-bonded core of closely compacted particulate filler, the loose filler is packed from a feed tube (14) into an extrusion (or pultrusion) die (10) by means of applied vacuum (27), within a sheath of glass rovings (12) which is used to draw the packed filler through the die. A liquid bonding resin is introduced either via a tube (30, Fig. 1) extending through the feed tube, or via the die (44, 31, 33) to permeate and bond together the packed filler and the sheath. The filler comprises coarser layer mineral foam particles and an additional free-flowing relatively finer material e.g. hollow silicate microspheres, quantities of the coarse and fine fillers being successively introduced into the die by the vacuum, so that the additional filler occupies the interstices of the previously packed coarser foam filler. The filler may be heated by a warm air heater (40). <IMAGE>

Title: Stereoscopic viewer having a pair of viewing lenses
Inventor: LO ANTHONY TAK-SAU
IPC: G02B27/22
Filed: 1988-05-19
Abstract: A viewer 10 for a stereoscopic pair of images where the stereoscopic pair 22 is mounted behind a pair of viewing lenses, preferably fresnel lenses, 12, 14 at a spacing less than the focal length so that a magnified virtual image is seen. The lenses 12, 14 are at least as large in width and height as the image of the stereoscopic pair 22. In this way long or short sighted persons can view the images in focus by holding the viewer at an appropriate distance from the eyes. The width-wise spacing between the optical axis of the lenses is such that the rays from the left and right hand images emerging from the lenses at the join between the two lenses are substantially parallel. In this way the user's eyes do not have to diverge when looking towards the lens to view the stereoscopic images and the lenses 12, 14 provide the equivalent of an optical wedge to bend the images as seen by the user in an outwardly diverging sense. The viewer may comprise a rangefinder (Figs. 8-10). <IMAGE>

Patent GB-2272046-A (GB)
Title: Explosive mines
Inventor: PRICE ANTHONY RHYS
IPC: F42B23/04
Filed: 1989-01-06
Abstract: A mine which is designed to defeat countermeasures such as flails and ploughs. Burying of a mine 30 centimetres, say, below ground level will defeat a flail or plough, the latter of which may take off the ground surface to a depth of 15 centimetres. However the "overburden", ie the soil or material which tends to fill the space above the mine after placement, can inhibit the proper operation of the explosive charge, normally requiring a clearing charge to displace it. The present invention overcomes this problem by fitting a telescopic canister 5 to the main charge compartment 3 to produce an enclosed space above the charge. The mine is laid in a drilled (or dug) hole and the telescopic canisters pushed down to just below ground level. Negligible resistance to the explosion is thus provided between the charge and the target above. The mine may comprise tandem hollow charges. <IMAGE>
