Title: Sleeved flangeless pipe union - has chains forming internal clamps accessible from outside through slots
Inventor: SCHERWARTH MANFRED
IPC: F16L21/08
Filed: 1980-11-18
Abstract: The flangeless union forms a sealed joint between two pipe ends, having a rigid sleeve (3) fitting over both (1,2) and containing a cylindrical internal recess (4,5) for each, accommodating an internal clamp (12,13). The middle part (3a) of the sleeve, either side of the point where the pipe ends butt, has an internal dia. such as to fit over them, while at its outer ends are support rings (6,7) enclosing the cylindrical recesses. Each of the latter contains a link chain (12,13) forming a clamp, and whose end links are bent over to form opposite eyes (17) for a clamping screw (18). The eyes protrude outwards through a transverse slot (19) in the sleeve to allow actuation of the screw. The chain links are so shaped that a tension load in the axial direction of the sleeve causes them to expand by wedging action. An inner clamping ring (8,9) is mounted between each chain and the middle part (3a), and has a ramp face (8a,9a) towards the latter, compressing a sealing ring (10,11).

Title: Sealing frame for electrodialysis membrane stack
Inventor: KNEIFEL KLEMENS
IPC: B01D61/50
Filed: 1981-02-02
Abstract: The sealing frames for alternately arranged anion and cation exchanger membranes of a membrane stack for electrodialysis include a net-like spacer for the membranes to be installed there. In order, in these frames, to maintain the net-like spacers securely in position, without increasing the thickness of the sealing frames, according to the invention it is proposed to form the rims (1a) of the net-like spacer (1), compressed into the plastic frame (3) to a value undershooting the thickness of the frame (3), in such a way that the thickness of the uncompressed part of the spacer (1), lying in the chamber, essentially corresponds to the thickness of the sealing frame furnished with linear seals (10-16). In this manner, very thin sealing frames are formed having a thickness of about 1.0 mm, so that the efficiency of an electrodialysis apparatus of a given volume is considerably increased. <IMAGE>

Patent DE-3108937-A1 (DE)
Title: Permanent way
Inventor: SCHWARZ GERHARD DIPL ING DR TE
IPC: E01B5/18
Filed: 1981-03-10
Abstract: In the case of a permanent way having frames (2), which are preferably made of reinforced concrete, which are placed alongside and aligned with one another in the longitudinal direction of the track and are used to support the running rails (1) of the track, supports (3), which are parallel to the running rails (1), are fastened to those parts of the frames (2) which are adjacent to one another and extend transversely to the longitudinal direction of the rails, to permit transmission of transverse forces in the expansion joints. The fastenings of these supports (3) which pass across the tops of the frames in the longitudinal direction of the track are closer to the expansion joints (4) of the frames (2) than are the supports (1'), which are respectively adjacent to the said expansion joints, of the running rails (1). In this fashion, the frames are connected in the region of the expansion joints in a manner which is articulated to a limited extent, but which is also flexible, i.e. elastic, to a limited extent, the connection on the one hand being able to absorb the transverse forces occurring when the track is passed over, and on the other hand being sufficiently rigid to prevent the dreaded "pumping" of the frames in the region of the frame joints. <IMAGE>

Title: Device for the clock supply of a central processor
Inventor: ELLWANGER KLAUS ING GRAD
IPC: G06F1/10
Filed: 1981-09-23
Abstract: The invention relates to a device for the clock supply of a central processor of a data processing installation, in the case of which the central processor is split into a plurality of mechanically autonomous structural units. One or two clock sub-distributors are arranged on each structural unit, in which clock sub-distributors the clock pulses originating from a central clock generator are switched through to the individual clock consumers or are inhibited in accordance with condition and/or braking signals. In contrast to the requirements in the case of a central clock controller, the time-critical braking signals can now occur later by the time it takes for the clock to pass between the clock generator and the clock sub-distributors. This also benefits the processing speed of the data processing installation. <IMAGE>
