Abstract: 997,987. Seaming non-metallic sheet material. G. MULLER. June 10, 1964 [June 12, 1963], No. 24075/64. Heading B5K. Sliding clasp fastener cases produced from synthetic thermoplastic foils welded by high frequency current and having margins or rims projecting outwardly beyond the point of fixing the sliding clasp fastener, welding being effected by a tool comprising upper and lower electrodes, are made by tensioning the fastener around a frame 1, turning the stringer edge of the fastener outwardly away from the frame 1 and welding the stringer edge in this position to a synthetic thermoplastic lining 10 disposed therebeneath so that the stringer edge forms the core of the projecting margins of the case. The frame 1, Fig. 3, comprises a strip of current-conducting material and the fastener is tensioned therearound so that the fastener members lie in a channel or groove in the frame. The two outer separable ends of the fastener are secured by U-shape spring clips 3 and the slide is placed in a transverse member 4. The projecting stringer edge is then turned outwardly away from the frame 1, this turning being facilitated by incisions 2. The lower electrode, Fig. 9, comprises current-conducting frames 6, 7 on a current-conducting base 5, the frame 7 being formed with a cutting edge. The lining 10 is laid on the frame 6 and the frame 1 carrying the fastener 2 is placed on the lining 10. A thermoplastic rim 11 is placed over the projecting stringer edge. An upper electrode comprising a frame 9 on a plate 8 is lowered to weld the rim 11, the projecting stringer edge and the lining 10 together. Suitable inserts may be placed underneath the lining 10. The lower electrode moves upwardly and carries with it the frame 1 with the fastener and the lining 10, the upper electrode having a filler plate 13 of foam material which clamps the frame 1 on the first lowering of the electrode. An outer covering 12, Figs. 11 and 12 (both not shown), and other inserts are placed on the lower electrode and the upper electrode is lowered and welding effected.

Abstract: 1300432 Multi-disc disc brakes; friction clutches; wear-compensating mechanisms B F GOODRICH CO 19 May 1970 [19 May 1969] 24199/70 Headings F2C and F2E An adjuster assembly for wear compensation in brakes or clutches has a movable elongate member 32 for axial displacement to the right in response to actuation, and to the left in response to release, of parts 17, 13, 12, 18, a series of mutually independent, laterallyseparated springs 37 each directed towards the elongate member, element 43 for engaging member 32 with one of the springs 37 when the member is moved in the release direction, housing 23, 24, supporting the springs for limited axial movement with corresponding movement of member 32, and shoulder 27 for arresting such axial movement so that member 32 is capable of further displacement to the right by successive deflection of successive springs when wear has occurred. In the disc brake shown, an hydraulic piston 15 moves pressure plate 17 to force discs 13, 12 against reaction plate 18. Plate 17 pulls with it a retractor rod 32 which, by engagement of a projecting ring 43 on it with spring washers 33 inside a housing 23, pulls the housing, the housing in turn compressing retractor spring 31 by means of flange 26. The housing has limited movement defined by ring 28 and shoulder 27, this being equal to the normal brake clearance, X, so if no wear has occurred, rod 32 is retained by washers 33 in the same position in housing 23 during repeated brake applications and releases. If wear has occurred, and the brake is not fully engaged when housing flange 26 reaches shoulder 27, plate 17 pulls retractor rod 32 further to the right, ring 43 passing one or more washers 33 to permit this. On brake release, housing 23 returns to ring 28 with the rod 32 in its new position. The "travel" of retractor spring 31 remains constant throughout. Pressure plate 17 and friction disc 12 are splined to a fixed torque frame 11 which includes reaction plate 18, while friction lining carrier 13 splined to rotary member 14 which may be part of a wheel.
