Title: Yoke
IPC: B66F7/28
Filed: 1979-02-28
Abstract: A lifting yoke, for example for a motor vehicle, has each end constructed as an open box comprising side plates (4, 5) with a vertical sleeve therein for receiving a stub shaft of a lifting fork 15. The upper edges of the side plates have teeth and grooves to co-operate with grooves and teeth on an upper horizontal plate secured to the sleeve and a further horizontal plate secured to the lower end of the sleeve limits lifting of the sleeve by abutting the lower edges of the side plates. The lifting forks (15) can thus be readily adjusted in position along the yoke by disengaging the teeth and grooves, moving the fork-receiving sleeves and then re-engaging the teeth and grooves. <IMAGE>

Filed: 1979-04-20
Abstract: A transistor protected against overvoltages comprises, a first low resistivity P type layer (2), a second high resistivity P type layer (4), and a third high resistivity N type layer (6) forming a first PN junction therewith. In the third layer (6) are formed a first low resistivity N type region (8), a second low resistivity P type region (10) defining a second PN junction, and a third low resistivity P type region (12) defining a third PN junction therewith. Metal layers forming collector (20), base (16) and emitter (18) terminals ohmically contact the first layer, first region and second region respectively as shown. The resistivity of the second and third layers (4, 6) and the distances between the first and second and first and third PN junctions are such that in operation, the base depletion region may reach the third junction but not the second. In a variant emitter region (10) is wholly within region (8) which is deeper and is apertured to accommodate a shallower third region (12). The conductivity types of the regions may be reversed. <IMAGE>

Title: Improvements in and relating to velour fabrics and their manufacture
IPC: D06N7/00
Filed: 1979-08-22
Abstract: Velour fabrics such as velvet are known and it is known to provide such fabrics in the form of a web having a plastics film on the surface remote from the pile. Direct application of the film gives rise to disadvantages because of the unevenness of the reverse side of the fabric and attempts to overcome these disadvantages have been unsatisfactory. The invention overcomes these disadvantages by first applying to the reverse side of the fabric a liquid foamed curable plastics material and curing this under tension to provide a flat surfaced open cell plastics layer 3 which acts as an advantageous substrate surface for the plastics film 4. <IMAGE>

Title: Asymmetric rubber bushing
IPC: F16F1/387
Filed: 1979-09-03
Abstract: In a resilient bushing of the type in which a rubber member 3 is arranged between and bonded to outer and inner metal sleeves 1, 2, the rubber/metal interfaces are oblique to the axis, so that axial forces F1 applied to the bushing produce radial displacement F* of the metal sleeves. Although the rubber member may provide a circumferentially continuous connection between the metal sleeves, such connection may be restricted to 180 DEG  or less where radial displacement is to be confined to a preferred direction. In Figure 4 the bushing has a first region in which the rubber-facing surfaces of the metal sleeves are straight, concentrically arranged cylindrical surfaces and a second region axially adjacent thereto in which said surfaces are frusto- conical, an axial extension of the rubber member extending between the two frustrums only on a circumferential region of less than 180 DEG . <IMAGE>
