Title: Gas turbine with axial compressors - has compression ignition combustion chamber with inlet and exhaust valves
Inventor: NIGG MARTIN
IPC: F02C5/12
Filed: 1976-03-13
Abstract: The gas turbine consists of a rotor (2) fixed to a shaft (3) and turning in a closed circular housing (1). Saw tooth-like impulse surfaces (8) surround the rotor edge and are cast as a unit together with the rotor. Two or more axial compressors (10, 11) are fitted radially outside of the turbine housing and are driven by the turbine shaft. The first compressor draws in atmospheric air, compresses it and passes the pre-compressed air to the second compressor until a final compression of 80 to 100 atmospheres is reached. The final compressor output is fed via a regulated inlet valve (16) to a combustion chamber containing a fuel injector nozzle (18) and an exhaust valve (17). Both inlet and exhaust valves are rotary valves actuated by regulator rods (19) and eccentres (20) from the turbine drive shaft. Fuel is injected into the combustion chamber when both valves are closed. The high compression existing in the combustion chamber causes spontaneous combustion, the exhaust valve opens and expanding gases act upon the rotor impulse edge and causes the rotor to revolve.

Title: Foam plastics electrical insulators with constricted sections - made using temp. controlled setting to give improved strength
Inventor: KUTSCHERA KURT DIPL ING
IPC: B29C44/04
Filed: 1977-12-15
Abstract: Parent patent describes a method of making foam plastics mouldings of differing internal and skin density, esp. for high voltage electrical insulation. Local cooling is used to produce the high density regions. Novelty is that at the location where the plastics flows through a construction during moulding, the internal face of the mould is subjected to a temp. pattern involving a lower temp. of the inner face of the mould in this region than for other parts of the inner face of the mould at the start of foaming, so that setting of the material is impeded in the constrictions; after this, the temp. pattern is controlled so that partial reheating of the mould from the outside is applied to the constrictions. Used esp. for constructing large electrical insulating components. The method ensures improved mechanical strength at the constrictions.
