Patent DE-2356315-A1 (DE)
Title: Joining of electrical conductor to contact face - arrangement and method using soft connecting medium
Inventor: MUZ EDWIN DIPL PHYS DR ING
IPC: H01R4/18
Filed: 1973-11-10
Abstract: the arrangement has an electric conductor connected to contact body by means of a pliable connecting medium. The electric conductor is at least partly embedded into the connecting medium and is locked with it into the contact body. Drillings in the body are at right angles to each other. Drilling is for receiving the cable and for the connecting medium which can be in the form of a ball and which after the squeezing process into the conductor and contact face engages beyond the diameter of drilling, into the drilling proper. There are alternative arrangements of contact faces, e.g. one with a length slit which ends in the receiving drilling.

Title: Gas turbine combustion chamber guide wall - has return flow combustion chamber and air cooled double guide wall
Inventor: MATTO LAWRENCE ROBERT
IPC: F23R3/54
Filed: 1973-11-10
Abstract: The compressor air flows through the diffuser along the channel to the return flow combustion channel where it mixes with the fuel from the jet and expands in the direction of the compressor. The combustion chamber guide wall deflects the expanding gases 180 deg. to turn the turbine rotor. Since the guide wall is subject to extreme high temp., the wall is formed as a double wall enclosing a chamber into which some of the comparatively cool compressor air is introduced via a row of holes in the top part of the outer wall, leaving by a number of holes in the lower section of the inner wall close to the power turbine. A number of depressions are made in the outer plate which touch the inner plate in order to act as a restrictor to the air flow.

Title: Lifting and tilting mechanism - has link point between lazy tongs links off-centre near stationary pivot point
Inventor: SANTIC BLAZ DIPL ING
IPC: B66F7/08
Filed: 1974-02-16
Abstract: The mechanism is for stationary or mobile loading equipment in multi-storey garages etc, and the load is raised and lowered by lazy tongs links on a frame. Two link ends perform circular pendulum movements converted by guides into straight-line lifting movements, and are on the same side of the vertical plane passing through the link point between them. The point link is situated off-centre near one of the fixed pivot points of the lazy tongs links, and the lack of symmetry of the lazy tongs linkage thus caused is counteracted by cranking the end of a link near the link point. The lifting movement is transmitted by a hydraulic ram to the free end of a lazy tongs link working in the load platform.

Title: Cct compensating interference effects - in system with light source and photodetector, transmission signal being dependent on illumination
Inventor: SCHMITT WALTER
IPC: G01D5/347
