Patent DE-2359521-A1 (DE)
Title: Coupling ring for snow chain - with detachable lock section to form part of ring, leaving centre of ring unimpeded
Inventor: WITZEL GUENTER
IPC: F16G15/02
Filed: 1973-11-29
Abstract: The coupling ring is used to join up snow chain sections and to replace damaged rings. The ring has an open section with profiled ends over which the coupling section is slid, from a lateral direction. The coupling section is then rotated about its long axis to lock into position on the profiled securing clips. The coupling section is shaped to form a continuous contour of the inside diameter of the ring so as to provide the maximum space inside the ring. This enables it to replace plain rings which join several strands of snot chain.

Title: Circular section rings of synthetic rubber, esp. O-rings - by injection moulding eliminating final accurate trimming operation
Inventor: SEIDL LUDWIG
IPC: F16J15/328
Filed: 1974-08-06
Abstract: A circular clamping ring, esp. an "O" ring of synthetic rubber, is produced by injection in a mould having a non-cavitating injection feed point positioned in a zone where there is no sealing action, and for pref. on the outside of the ring between the upper or lower sealing zone and the central side sealing zone.

Title: Wine fermentation tank residue extn. - by gear motor driven screw conveyor on universal joint suspension of frame
Inventor: LINK ROLF
IPC: C12G1/00
Filed: 1975-05-27
Abstract: Solid residues are removed from tanks, such as are used for wine fermentation, by introducing through a manhole a screw conveyor which is coupled to the output shaft of a gear motor.

Title: Spacer and oscillation damper for overhead HT transmission lines - has foam-filled tube to anchor ends of spacer arms
Inventor: DECKER ERNST
IPC: H02G7/12
Filed: 1975-07-28
Abstract: The spacer comprises a central block and arms equipped at their outer ends with clamps which are fixed around the component cables of the conductor. The main block consists of a tubular casing contg. rubber-elastic component(s) inside or between which the inner ends of the arms are housed; these inner ends of the arms have thickened or bulging regions which are gripped in or between the elastic blocks, so that the arms have limited elastic resilience. Pref. the main block comprises a tube with constricted ends. Used for spacing apart the individual cables of one phase of an overhead high tension line, to prevent them from banging together and to ensure that they oscillate at the same frequency. The spacer is simple to contruct and has a long working life without losing its damping action. The rubber-elastic components may be of polyurethane foam; alternatively, the tube is entirely filled with polyurethane foam, in which the bulges of the arms are firmly anchored.

Title: Masonry building block wind load resistant retaining device - with end piece on mortared lengthways unit enveloping structural side piece
Inventor: HAINES NORMAN WILLIAM
IPC: E04B2/58
Filed: 1975-09-02
Abstract: The masonry block retaining system is suitable for buildings comprising columns and a masonry walling which must be anchored to them, at set intervals, in such a way as to ensure additional support against wind loading and other lateral pressures. The device incorporates a firm lengthways component (21), with a piece in its end area to grip a side piece (16) on a building structure component (11).

The latter may be in the form of a groove (19, 23), extending inwards from a longitudinal edge of the lengthways component. The masonry building blocks can be effectively anchored to a building structure, without any assistance or special tools being needed by the mason.
Patent DE-2539224-A1 (DE)
Inventor: MUKAIYAMA FUMIAKI
IPC: G04G5/00
Filed: 1975-09-03
Abstract: The time information of a time measuring instrument (1) is corrected by its approach to the transmitter (3). During the correction operation, a clock pulse generator (9) arranged in the time measuring instrument transmits its time pulses B to a circuit (8), which stores the correction signals in series, and to a counter (13). The counter receives the correction signals in parallel from the storage circuit. This produces a simplified circuit for correcting the time information, which is operationally convenient and presents no problems. <IMAGE>
