Patent DE-2321842-A1 (DE)
Title: Electrochemical cell - with simple gas safety valve
Inventor: SHINODA KENICHI
IPC: H01M2/04
Filed: 1973-04-30
Abstract: The cell comprises a metal housing constituting one electrode and a top lid constituting the other electrode, with an insulating seal in between them and a gas escape valve to release excess gas pressure. The metal housing is generally cylindrical and is terminated at the top end by a zig-zag or undulating form constituted of a first, inwardly slopping, frustoconical portion, followed by a second, outwardly sloping, frustoconical portion followed again by a third inwardly sloping portion; the first and second sloping portions thus constitute an external groove; the sealing arrangement comprises a first, flexible sealing ring contained between the upper, inner face of the second sloping portion and the underside of the lid and a second annular seal contained beneath the underside of the third sloping portion and the upper edge of the rim of the lid. This second annulus is a higher elasticity than the first and both are compressed between the third and second sloping portions of the wall. The gas discharge openings are around the curved part of the second sloping portion and close to the external perimeter of the first annular seal. The metal wall of the vessel is faced on the outside with plastics, pref. a hot-shrunk plastics glued to the upper insulator using PVC adhesive. When excess gas pressure build up, the first seal lifts off the second portion of the wall, permitting gas to escape through the openings.

Title: Rotating shaft with pneumatic engageable switch coupling - has oil pressure produced in enclosed part-filled system, with compressed air feed to ring space around shaft
Inventor: CHIVARI ILIE
IPC: F16D25/06
Filed: 1973-06-16
Abstract: Pneumatic engageable switch is for connecting a rotating shaft to a rotatable component, in which compressed air is fed to the coupling via a channel in the rotating shaft itself. The compressed air channel opens into the outer surface of the shaft, the shaft is enclosed in a stationary housing, which forms a ring shaped space in the region of the compressed air channel exit. Compressed air can be introduced into this ring space and on both sides of it, between the housing and the rotating shaft, air tight shaft seals are fitted which are in contact with oil pressure on the outside. The oil pressure is adjustable for the limitation of the pressure difference effective on the shaft seals dependent upon the pressure of the compressed air. The oil pressure is statically produced in an enclosed, partly oil-filled system which is connected above the oil level with a compressed air feed line to the ring space. The oil used is of high viscosity.

Title: Radiotelephone network automatic zone switching - takes place when reception voltage in mobile station falls below given limit
Inventor: JOHAN DIPL-ING BRAAK DIRK
IPC: H04W36/08
Filed: 1973-10-13
Abstract: Each zone has a basic radio station and its own group of radio speech channels. At or after connection build-up between a wired subscriber and a mobile radio subscriber, the number of the line from or to the wired subscriber is transmitted by the radio relay station to the mobile radio telephone station and there stored. The channel number of at least one free speech channel in each adjacent zone is transmitted to the mobile station and there stored. When reception voltage in the mobile station falls below a limit, it is switched over to a search run which finds a free channel, whose number was stored, with a higher reception level; the connection is re-established by transmission of the wired subscriber number and its own number over the new channel to the new zone station.

Title: Hammer crusher with rotor hinged hammer - is C-shaped with crushing edge at tip of each C leg
Inventor: PICKERS HANS JOACHIM
IPC: B02C13/28
Filed: 1974-02-09
Abstract: The C-shaped hammer is provided with two bores intended for alternative use. The bores are positioned on the same vertical centre line. The hammer is fitted on the pivot of the rotor using one of the bores as seating. The position of the hammer on the rotor is such that the tip of the C-shape points in the direction of the rotation, and the bore not used for seating is farther away from the rotor centre. The positions of the two bores are arranged in such a way that the centre line connecting the two bores divides the surface of the hammer into two partial masses. The partial mass incorporating the crushing edge in use, multiplied by the distance of its centre of gravity from the hammer pivot, is larger than the corresponding product of the other partial mass.
