Patent DE-3834731-A1 (DE)
Title: Device for anchoring or connecting concrete reinforcement bars and process for producing the same
IPC: E04C5/16
Filed: 1988-10-12
Abstract: In order to connect concrete reinforcement bars provided, on the surface, with profilings, e.g. in the form of ribs, in each case one metallic sleeve (3, 3') is pressed onto the ends of the reinforcement bars (1, 1') to be connected, and said sleeve is provided, over at least part of its length, with an external thread (4). A connecting body (8) provided with a corresponding internal thread is screwed onto said external thread (4). The sleeves (3, 3') thus serve only as an intermediate member for imparting a force transmission between the actual connecting body (8) and the bar ends. The advantage lies in the fact that the bars (1, 1') themselves do not need to be machined, and that the length (L), which the connecting body requires for force transmission with the pressed-on sleeves (3, 3'), lies within the length (l1, l2) which said sleeves, for their part, require for force transmission onto the bar; the bars (1, 1') can thus be connected to one another over an extremely short distance. <IMAGE>

Title: Method and device for separating sheet-like material
Inventor: SCHULZE PETER DIPL ING
IPC: B65H3/60
Filed: 1988-10-31
Abstract: The invention relates to a method and a device for separating sheet-like material which is subsequently printed by the offset printing method. The object, to provide a method and a device for separating sheet-like material, the separation and transportation to the transporting roller or to the gripper system being intended to take place without weighty means, is achieved in that a pressure pulse is introduced at the trailing edge of the sheet pile, as a result of which a wave passes into the system in the form of a pressure wave which passes through up to the leading edge of the sheet, is reflected there, and continues in the opposite direction as a tensional wave and thus detaches or loosens the sheet at the next boundary between the wave conductor and the sheet pile and thus imparts an initial speed to the sheet in the direction of the feeder of the printing machine. <IMAGE>

Title: Braided rod or tube mfr. - uses resin immersed fibre strands spirally wound around core to give braided body with high torsional strength
Inventor: PABSCH ARNO DIPL ING
IPC: B29D28/00
Filed: 1990-02-23
Abstract: A rod-shaped body is formed by a number of spiral windings of fibre strands immersed in synthetic resin wound in pairs round a core at a pitch angle of 30-60 deg., with the same pitch in all the coils. The axial gap between the coils corresponds to the number of windings in the same direction multiplied by the width of the fibre strands. The strands are wound so that, in succession in the same winding direction, they are displaced from the underlying strands wound in the same direction by the fibre strand width. The fibre strands for the separate coils are pref. wound so that all those in the same direction lie over the coils wound in that direction with a mean strand gap which is more than twice the strand width, and each has an axial gap which generally corresponds to twice the strand width. The fibre strand width between the crossing points is less than at the crossing surfaces. The gap (c) between the fibre strands in the separate coils is structured as c = (n/2-1) where n is an even number of windings. ADVANTAGE - The system gives a braided rod or tube structure, which can withstand high torsional stresses without damage, and which can be produced in a continuous mfg. process.
