Title: Process for the production of articles of a cellular plastics material provided with a covering of another material
IPC: B29C39/10
Filed: 1974-06-13
Abstract: 1479893 Moulding foamed articles having an outer covering layer SAAB-SCANIA AB 13 June 1974 [18 June 1973] 26287/74 Heading B5A In a method of moulding an article by placing a covering sheet in a mould and filling the mould with a foamable plastics material which expands to fill the covering sheet and form a cellular core, the sheet is coated on the side facing the foamable material with a substance which causes acceleration or retardation in the rate of the reaction forming the cellular plastics; this results in the formation of a temporary layer of reduced adhesion in the plastics material whereby the plastics material is able to expand freely in the mould during foaming. In the examples, the foam is polyurethane and the outer covering is PVC treated with (a) a polyurethane varnish containing excess polyol component, (b) an isocyanate or (c) a tertiary amine. Another suggested combination is an epoxy resin forming the cellular core and a covering layer of a thermoplastic/textile laminate treated with a tertiary amine. It is also stated that the outer covering may be a metal or a textile material. A heat softened covering sheet may be plastically deformed by the expansion of the foam. Door panels for vehicles are made.
Patent GB-422002-A (GB)
Title: Improvements in or relating to positive bi-directional clutches
IPC: F16D13/12
Filed: 1933-09-26
Abstract: 422,002. Positive clutches; variablespeed gearing. CARLING, W. T., Tangley, Sydney Road, Guildford. Sept. 26, 1933, No. 26448. [Class 80 (ii)] Two-stage locking means for preventing inopportune engagement of a positive clutch, in constant-mesh change-speed gearing, comprises a disc C which encircles the female driving member A, is capable of limited angular movement thereon by reason of projections B<1> extending from a flange B on the member A into arcuate recesses C<1> in the member C, and is also capable of axial movement, limited by lugs B<2> on the projections B<1> under the action of spring-loaded plungers C<4> carried by the disc C. At the limits of angular movement of the disc C, the plungers engage depressions in the flange B. Arcuate elements D pivotally carried by or radially guided in the disc are normally urged inwards by springs E, in which position they are interposed in the path of movement of the slidable male driven member M. The face of each element D adjacent the member A is stepped at D<2> and is also formed with non-planar shoulders G, G<1> adapted to co-operate with longitudinal pins H which are secured to the flange B and project through arcuate slots in the disc C. Resilient fingers K secured to the disc have V-shaped ends K<1> adapted to be engaged by the teeth of the member M so as to cause angular movement of the disc C ; alternatively, this movement may be caused by friction between the periphery of the teeth of member M and a bore in a second disc secured to the disc C. The clutch teeth may be bevelled as described in Specification 359,609. In operation, with the member M overrunning the member A, clutch engagement is prevented by the elements D, ratcheting of the teeth of member M over the fingers K maintaining the parts in the position shown in Fig. 1. The member A is now speeded up to overrun the member M, when the action on the fingers K will cause the disc C to move to its other angular position, and during such movement the pins H engaging the shoulders G cause the elements D to be moved outwards sufficiently to permit the member M to move the disc, by reason of the step D<2>, towards the flange B. The member A is now slowed down until the member M overruns, when the disc C will be returned to its original angular position, in the course of which the pins H coact with the shoulders G<1> to move the elements D outwardly to such an extent as to free the member M from further restraint. The member M may now be moved into engagement with member A, the fingers K passing through the teeth of the former. If the member A is overrunning the member M when engagement is attempted, it is only necessary to slow down the member A to permit engagement. In order to enable engagement to be effected when the driven member is stationary, a main clutch stop, effective to produce a slight reversal of the member A, may be provided, as described in Specification 298,313 or 332,706, [both in Class 80 (ii)].
