Title: Improvements in friction clutch stops
IPC: F16D67/02
Filed: 1927-08-08
Abstract: 298,313. Carling, W. T. Aug. 8, 1927. Gearing for stop ping and starting machinery; facilitating changing speed -In order to facili tate gear - changing on motor - vehicles motor-boats, &c. a clutch stop is pro vided comprising a brake disc &c. adapted, on disengage ment of the main clutch, to engage means on the driving shaft of the gear-box to bring it to rest and thereafter turn it backwards. This backward rotatior may serve automatically to release the locking- device for preventing inopportune engagement of claw clutches described in Specification 282,121, or to facilitate meshing of sliding gears or claw clutches not provided with such locking- devices. The driven part 2 of the main friction clutch (not shown) is mounted on the gear-box driving-shaft 1 and carries a flange 3 adapted to contact with a brake-surface 4 on the clutch-stop member 9 which is loose on the boss 7 of a recessed stationary part 6 and has a stop 11 and; arm 10 projecting through slots 12 in the wall of the part 6, whereby its rotation is limited. Spring-pressed antifriction balls 14 hold the member 9 against a retaining-ring 13. On full depression of the clutch pedal, the member 2 is braked and turns the part 9 against a tension spring 15. If the part 9 is allowed to contact with the face of the part 6, slight release of the pedial is necessary before spring 15 can effect reversal of the shaft 1, but if a limiting-stop be provided for the pedal, shaft 1 will be reversed as soon as it has come to rest. The Provisional Specification describes the form requiring release of the pedal as particularly applicable to changespeed gears without the locking-devices referred to.

Title: Method for the surface treatment of pressboards
IPC: B27N3/06
Filed: 1963-05-27
Abstract: 1,036,798. Laminates and laminating. F. MRACNA and J. G. MERAN, [trading as HOLZTECHNIK ANSTALT]. May 27, 1963 [May 26, 1962; July 12, 1962], No. 21017/63. Heading B5N. A method for surface treating press-boards consisting of one or more layers of compressed, bonded, fibrous particles, with at least one resinated absorbent layer such as paper or textile material is characterized in that the surface layer is not treated with the resin until just before it is pressed on to the surface of the board during the manufacture of the latter. Boards containing compressed, bonded, fibrous particles are made by adding the fibrous material in a pulp-like form to one side of a recently resin-treated surface layer contained within a press, optionally adding a similar top surface layer, and finally pressing at an elevated temperature. When large fibrous particles are used, a layer of smaller particles e.g. sawdust, may be added to prevent the surface layers from bulging. This problem may also be overcome by roughening the inner surface of the surface layers or by coating them with cellulose, plastics or similar fibres by flocking. The surface layer may be a light-sensitive paper bearing a positive impression to provide a decorative surface. In an example, surface-treated chipboard is produced comprising outer sheets of plain, coloured or printed paper soaked in 50% aqueous melamine resin solution, the chipboard itself comprising a central layer of chips 20 x 10 m/m in size, intermediate layers of chips 5 x 10 m/m in size and outer layers of sawdust. These various layers are moistened with urea, formaldehyde and hot pressed with the outer sheets.
