Title: Improvements in coin separating wheels
IPC: G07D3/06
Filed: 1962-12-20
Abstract: 958, 741. Sorting coins. G. PRUMM. Dec. 20, 1962 [Dec. 23, 1961], No. 48068/62. Heading G4X. The transporting wheel 14 of a coin sorting machine picks up coins in slots 15 and 16 of different widths. Since the large diameter coins are likely to be few, proportionately few wide slots 15 are provided and the other slots 16 are narrower. As compared with a transport wheel in which all slots are wide enough to transport the coins of largest diameter, the invention allows the provision of more slots and the transport of more coins per revolution. Coins are selected by slides 17 which are withdrawn from beneath the slots by means of rollers 19 working on a cam 18 to determine the radial position at which coins of a given diameter are released.

Title: Improvements in rubber bearings for pivotal joints
IPC: F16C11/04
Filed: 1962-12-20
Abstract: 1,021,547. Pivot bearings. DAIMLERBENZ A.G. Dec. 20, 1962 [Dec. 23, 1961; Oct. 5, 1962], No. 48209/62. Heading E2F. A resilient pivotal bearing comprises an antifriction cylindrical bush 112 made of semi-resilient synthetic plastic material directly surrounded by a cylindrical rubber bush 110, the plastic bush having a wall sufficiently thick to make it relatively rigid as compared with the rubber bush and having an axially extending slit (not shown) to give it a resilient property so that it is caused to bear against a counter-bearing surface 119 with an initial tension produced by the elastic contraction of the rubber bush. The bushes are formed at one end with flanges 111, 113 to prevent relative axial movement, and the rubber bush 110 may have an inwardly extending flange at the other end engaging the surface 119. The adhesion between the bushes may be achieved by friction alone. The bearing is suitable for use in the joints of vehicle suspension and steering linkages.

Title: Web guide for intaglio printing mechanisms
IPC: B41F9/00
Filed: 1977-11-21
Abstract: A web (21) to be printed is conveyed over guide rollers (23, 24) of a web conveying system and over an impression cylinder (26). One (24) of the guide rollers is mounted so as to be freely rotatable on the support of the impression cylinder (26) and of a back pressure roller (27). The other guide roller (23) is firmly connected to slides (23.1). The slides (23.1) are connected in an articulated manner to the bearing shells of the one guide roller (24) by means of a coupler (29). The position of the guide rollers (23, 24) relative to one another is coordinated such that, when the impression cylinder (26) is raised from the forme cylinder (28), the shortening of the web (21) thus caused is compensated by displacing the other guide cylinder (23). After renewed engagement of the impression cylinder (26) on the forme cylinder (28), printing can be continued in register with the colours printed prior to the raising of the impression cylinder (26). <IMAGE>

Abstract: 1277226 Sheet forming BRITISH LEYLAND (AUSTIN-MORRIS) Ltd 2 Oct 1970 [2 Oct 1969] 48508/69 Heading B5A An apparatus for forming seat covers for motor cars comprises a roll 1 of expanded vinyl sheet which is intermittently fed by means of a chain conveyer (7), having spikes (8), Fig. 3, not shown, to a hot air preheater 3, a vacuum forming mould 4, and a cutting unit 5. Three rolls 1 are supported on arms 40 rotatably mounted in a frame 38, and in order to maintain the supply each roll is joined to the preceding one by adhesive tape. The sheet is fed by rollers 29 on to a load sensitive platform 32 having a switch 34 controlling a drive motor 31. The rollers 29 can apply french chalk to the sheet. From the platform 32 the sheet is picked up by the conveyer (7) and passed through the preheater 3. Mould 4 has a two-part clamping frame 11, the upper part of which can be raised about a vertically movable hinge 15, and panel electric heaters 12 which can be moved laterally to extend above and below the sheet. The sheet is stretched by blowing air, before a vacuum form tool 14 is raised to an operative position, where upon the upper surface of the sheet is cooled by spraying with water and air. Each time the upper part of the clamping frame is lowered it actuates a punch 17 to pierce a hole in the sheet, and when the hole is aligned with a photo-cell 18, the drive from a motor 19 driving the conveyer (7) is interrupted to index the sheet in the correct position. The cutting unit 5 has a platen 21 with an endless cutter blade 24. It also incorporates a flute welder. A guillotine severs the residual sheet which falls into a receptacle 36. The flute welder can be disposed between the mould 4 and cutting unit 5.

A process for smelting a mineral product, containing as its major metal constituent copper, zinc or a mixture thereof, comprises injecting the mineral product, finely divided flux, an oxygen containing gas and optionally a fuel into a bath of molten slag in order to obtain a vaporized mixture containing a reducing gas and a constituent of the mineral product which may be recovered therefrom, and a non vaporized portion. If zinc oxide is the mineral product the zinc is vaporized along with e.g. lead from which it may be recovered, after condensing, by refluxing, and any copper present is recovered as a matte. If copper concentrate in the form of the sulphide is the mineral product the sulphur is vaporized in the form of H 2 S, COS or SO 2  from which S may be obtained by reaction with further SO 2 , and a copper matte containing e.g. Fe and precious metals but deficient in e.g. Zn and Pb is obtained as the non vaporized portion.
