Abstract: A fastening element is provided for connecting mechanical parts to one another. The fastening element includes integrated, cutting machining grooves which are designed to work the edges of the hole, during fixing of the fastening element, by the removal of material in the parts to be mutually connected, so that the hole is made to fit against the shell surface of the fastening element. A fastening element can be provided which, in a cheap and simple manner, is designed to absorb both occurring shearing loads and compression/traction loads between the connected parts.

Abstract: A sheet feeding table has pull-type side lays and front lays. Mounted beneath the feeding table and nearer the front lays are suction drums spaced apart and rotated by a transversely extending drive shaft on which they are mounted. The shaft is driven through toothed wheels having relative axial movement with respect to each other. A cam plate rotates with the shaft and a pair of fixedly mounted rollers guide the cam plate and impart reciprocating motion to the shaft and the suction drums. The lateral shifting of the suction drums clears the sheet from the pull-type side lay for the successive sheet. Each drum has a suction piece sealed and biasedly positioned adjacent a portion of the inside peripheral surface of the drum which rotates thereby and brings the drum suction holes into communication with the suction chamber within the suction piece. The suction chamber is in communication with a vacuum supply and a control valve is interposed in the supply. The sheets are fed to an impression cylinder having front stops and a series of sheet grippers. The speed of the drums is raised somewhat excessively to convey the sheets against the front stop in the impression cylinder.

Abstract: The web of paper (1) which is folded and possibly cut longitudinally in the former (92) is cut transversely (5, 6) to the book length and moved onto a collecting cylinder (9) for collecting layers of paper. The latter are passed onto a transfer cylinder (12), bound longitudinally thereon by means of a device (13), then folded longitudinally (15) and delivered (19). The collecting cylinder is designed for the largest format to be processed. The transversely cut sheets of paper are conveyed to the collecting cylinder (9) by means of a conveyor belt (7) which can run at various speeds. As a result, shorter or longer sheets of paper can be fed more rapidly or more slowly to the collecting cylinder (9), and the subsequent transfer cylinder (12) also runs at an adapted rotary speed. The subsequent longitudinal folding takes place by means of a rotating folding blade (15). A higher throughput can thus be achieved in a simple manner since solely rotating members (5, 6, 7, 9, 12, 13, 15) are used. <IMAGE>

Abstract: Two vulcanisation processes are proposed: in the compression process (Fig. 2a) shaped pieces (5') of rubber with a smaller base area than the metal surface (4) to be covered are placed on such that the press plunger (1) of a compression device spreads out the rubber on the metal surface (4) opposite to or at an angle to the loading direction. In the injection process (Fig. 3) flowable rubber (27) is applied at an angle between zero and 45 DEG  to the plane of the metal surface (4, 4'). In order to compensate for different adhesion properties between the vulcanised-on rubber and the metal surface, in the initial phase of vulcanisation, the metal part is rotated by up to 180 DEG  with respect to the applied material in the case of rotational parts and in the case of flat bodies is moved back and forth. It can thereby be achieved that zones having initially lower peel strength can be brought to a peel strength which is approximately 100% higher. <IMAGE>

Abstract: A method of joining two metal members to a graphite member to form a structure having a low transition resistance is described. The method includes the steps of providing a plurality of openings in the graphite member, interposing the graphite member between the two metal members and positioning the metal members to cover the openings in the graphite member, and resistance spot welding the metal members to the graphite member at the openings in the graphite member. This method is advantageous in forming a bus-bar connection between a pair of opposite polarity graphite electrodes in an electrochemical cell stack, such as a zinc-chloride battery. In this particular application, it is preferred that titanium be used for the metal members.
