Title: Improvements in grinding control method and apparatus
Inventor: SMITH RODERICK LOWE
IPC: B24B53/00
Filed: 1984-03-26
Abstract: Grinding control methods and apparatus pertaining generally to maintaining the shape and sharpness of a grinding wheel 20 despite the tendency of the wheel face to deteriorate from the desired shape and sharpness, as grinding of a given workpiece 24 or a succession of workpieces proceeds. Generally, as a common denominator of the novel features disclosed, a "conditioning element" 50 is brought into rubbing contact with the face of the grinding element under specially controlled and unique conditions to (i) restore the desired shape (conventionally called truing), or (ii) to establish the desired degree of sharpness (conventionally called "dressing"), or to accomplish both (i) and (ii) simultaneously. The method and apparatus disclosed include creating the aforesaid controlled rubbing contact either while the grinding wheel is free of grinding contact with a workpiece or simultaneously while grinding is occurring, and then either continuously or intermittently. The methods and apparatus in many of their various embodiments involve use of a "truing element" or a "conditioning element" which may be a generally homogeneous metal, and in many cases the same metal as that of the workpieces being ground. The disclosed inventive features involve truing of wheel faces in a fast, economical fashion by controlling relative surface speeds and feeds of the wheel and the conditioning element. <IMAGE>

Title: Making moulds
Inventor: SMETHURST EDWARD
IPC: B21K5/20
Filed: 1986-09-18
Abstract: A method of making a female mould includes the steps of pressing a male pattern of a material of which the index of strain rate sensitivity (m) is less than 0.35 into a block of an alloy in a superplastic state by a slow speed pressing operation whereby to form the female mould form in which the required object may be cast or moulded. In a first example, a male pattern of high speed steel is pressed into a superplastic block to form the female mould. The female mould cavity is then chromium plated. A male form is moulded by pressing further superplastic material into the female mould. The male form is then nickel plated. Polycarbonate female mould shells are then moulded around the male form. The polycarbonate female mould shells are then used to make confectionary. In a second example, a male pattern of high speed steel is pressed into a superplastic block to form a female mould. The female mould is then used for moulding rubber.

Title: Apparatus for stripping insulation from cables
Inventor: REEVE PETER WILFRED
IPC: H02G1/12
Filed: 1987-04-14
Abstract: This invention relates to apparatus for stripping the outer electrical insulation from a predetermined size cable. A blade holder (1 Figs 1a & 1b) comprises two halves 8 which define an open ended slot (2). Two generally planar blades 5 are located between the halves 8, each having a slanted cutting edge 7. The blades are mounted in the holder to define a slot 13 between opposing faces 6. An end portion of a cable 4 is inserted transversely into the slot 14 so that the outer insulation 17 is presented to the blades 7 at the correct angle and is then cut by the blades 7 before the faces 6 are forced into the cut in the insulation. During the stripping process, it is the edges 6 that take the stress separating the end portion outer insulation from the outer insulation of the remainder of the cable so there is a reduced likelihood of the edges 6 breaking. A tool for the holder is also described (Figs 4 & 5) that receives two holders. <IMAGE>
