Title: Stud driving or extracting apparatus
IPC: B25B13/50
Filed: 1980-12-22
Abstract: The apparatus has a housing 1 in which a number of rollers 7 are arranged held in a cage 6. By rotating the apparatus, the rollers engage on one side on ramp surfaces 17 of the housing, which form planes inclined to the axis of rotation, on the other side on a stud, so that the rollers grip the stud through the effect of the ramp surfaces. So that the apparatus can be used for studs of different diameters, the cage is made flexible with fingers extending from a ring- shaped part and retaining the rollers. The finger ends fall within the nominal diameter of the bore which serves to admit the stud, to prevent stud loss. <IMAGE>

Title: Carbon deposited on fibre by glow discharge method
Inventor: GREEN GEOFFREY WILLIAM
IPC: C03C25/106
Filed: 1982-08-06
Abstract: A fibre such as a glass optical fibre is coated by a glow discharge method in which an anode and cathode structure ionise a hydrocarbon gas such as butane, carbon ions are attracted towards the cathode, and the fibre to be coated is arranged close to the cathode and receives a stream of carbon ions which build up into a hard layer. Thin bonding layers e.g. of oxide, silicon, or germanium may be deposited prior to the carbon coating. Apparatus for the deposition includes a chamber containing a cathode structure. This cathode may be a series of segments 16 arranged in a helix along a fibre 8 to be coated. Alternatively the cathode may be a strip twisted into an open helix, a tube with apertures arranged along a helical path, or a tube of an open mesh material. Surface deterioration of the flbre is inhibited thereby. <IMAGE>

Filed: 1984-02-09
Abstract: A reversible garment (e.g. trousers) has an opening closed by a zip fastener with a slider (40) and covered by a fly. Fig 5 is a cross-sectional view. Seen from side (B) the fly is a fabric flap (6) attached where one zip tape (18) is secured, the flap extending so as to cover both halves of the zip fastener (18 and 19) whilst the second tape (19) of the fastener is not otherwise fully covered by other fabric on that face (B). The second zip tape (19) is secured to a facing piece (28) which joins the two pieces of fabric (12, 14) constituting the body of the garment. Seen from the other face (A) there appears a conventional fly front (36) provided by a short extension of the fabric (14) which does not overlap the fabric on the other side of the zip. Thus the fly opens in the same manner, i.e. to the left- or right-hand side (female/male), on each face of the garment even when it is reversed. <IMAGE>
