Title: Indexing device
Inventor: SAMUAL WALTER DANIEL
IPC: B23Q16/08
Filed: 1986-10-20
Abstract: In a precision indexing device such as a machine tool a workpiece carrier 3 is indexed relative to a support 6 by selectively engaging and disengaging a pair of coupling members such as the toothed gears of a Hurth coupling 1,2. Location means is provided between one of the coupling members and one of the support and carrier. As shown this comprises first and second ring elements 4,5 confronting with included V grooves 19 maintained in alignment with a locating ball 20. The first element 4 is connected to one coupling member 1 and is movable via control piston 10 which defines a cam surface 21 to control radial movement of the ball between engaging and disengaging relationship with a second coupling member 2 connected to carrier 3. The second ring element 5 is connected to support casing 6 and second ring elements 4,5 confronting with mutually inclined 'V' grooves 19 maintained in alignment by a locating ball 20. The first element 4 is connected to a gear coupling member a and moves with a control piston 10 to engage and disengage the member 1 with a further coupling member 2 connected to a carrier 3. During the movement radial movement of the ball 20 is controlled by contact with a cam surface 21 on the piston 10 to maintain alignment of the element 4 and the second element 5 which is connected to a support casing 6, and hence between the coupling member 1 and support casing. <IMAGE>

Title: Paste-the-wall wallcoverings
Inventor: GRAHAM THOMAS
IPC: D21H27/30
Filed: 1988-06-28
Abstract: A paste-the-wall wallcovering has a deep emboss paper ply (10a) adhered to a flat plastics ply (16) having perforations (22). The ply (16) can restrain the ply (10a) against any significant expansion in the course of hanging and paste drying. The perforations (22) are regulated on the one hand so that weight loss from the hanging paste is not so excessive that the paper ply becomes softened and, on the other hand, so low that tacking of the wallcovering to the surface on which it is to be adhered is not unduly delayed. In making the wallcovering the paper ply is moistened and embossed and allowed to dry just below ambient humidity prior to laminating it to the plastics ply. The wallcovering may be decorated in the course of manufacture or after hanging. <IMAGE>
