Title: Universal coupling with grooved chambers - has joints sliding and hinging in grooves and connected to link seats
Inventor: GERMAIN JAMES LEONARD ST
IPC: F16D3/16
Filed: 1978-01-19
Abstract: The universal coupling has first and second housing sections spaced apart, each with a chamber having grooves in it at intervals. The opposite ends of a link are accommodated in the respective chambers in the installed position and are curved, having seats at particular points round the periphery at intervals, acting against points inside the respective chambers.

Patent DE-2808438-A1 (DE)
Title: Longitudinal moisture ingress sealing of power cables - consists of rubber inserts extending along about two per cent of cable length
Inventor: KLASS JOACHIM ING GRAD
IPC: H01B13/02
Filed: 1978-02-27
Abstract: The application is to medium and high voltage cables with transposed or twisted wire cores which have to be sealed against the ingress of moisture longitudinally along the wires. The seal is made by treating short sections of the core with a polymerised rubber. The ratio of seal length to length between seals is of the order of 1:50. Use of a rubber as the seal does not reduce cable flexibility, and thus ensures that there are no unacceptably high stress points, when the cable is bent.
Patent DE-2810333-A1 (DE)
Title: Household mains supply junction box - has covers for consumer and electricity board compartments connected by sealed screw to form unit
IPC: H02B1/46

Title: Deoxygenation of water using oxygen-free nitrogen - using washing and degassing columns the outlet gas from which passes through catalytic converter after addn. of hydrogen to remove oxygen
Inventor: TAMURA TAKAAKI
IPC: C02F1/20
Filed: 1978-08-29
Abstract: Dissolved O2 is removed from a liq. using a sealed purge washer in which O2-free N2 is bubbled through the liq. It then overflows into a separator vessel where any bubbles are separated. By this means dissolved O2 is replaced with N2. The gases displaced have H2 injected onto them. They are then passed into a catalytic converter where the O2 is converted into H2O. The gases can then be recycled. The prod. liq. essentially water free. Used for removal of O2 from liq. streams e.g. water for reagent purposes or food preservation. allows complete removal with heating or chemical treatment.

Title: Automatic refuse shredding machine - has two counter-rotating cylinders with speed differential and third higher speed after shredder
Inventor: VOELSKOW PETER
IPC: B02C18/14
Filed: 1979-10-29
Abstract: The shredder for bulky materials, such as domestic, or industrial refuse consists of cylinders counter-rotating at different speeds. The two cylinders are positioned with gap between them and carry circumferential ribs provided with sets of tearing teeth. The shredder is fitted with a mechanism, which reverses the rotation of the two cylinders if a rigid piece of material enters the gap so that it is ejected through flap by one of the cylinders rotating in the opposite sense. It also possible that following the occurrence of a hard object only the slower cylinder is stopped, while the high speed cylinder proceeds to grind down the now stationary object. The set of the two cylinders is complemented by a third cylinder which operates as an after shredder.
