Title: Small firearm barrel of changeable performance - has perforated barrel and masking sleeve with gas diverting channels
Inventor: JONISKEIT DETLEF
IPC: F41A21/28
Filed: 1975-09-25
Abstract: The barrel for small firearms is designed for reducing the bullet velocity. This barrel is used for firing or standard ammunition. The bullet velocity is reduced so that the noise of the bullet caused by its supersonic velocity vanishes. Standard ammunition can also be fired at normal performance. The barrel (1) has transverse bores for diverting firing gases. These holes, however, can be masked by a sleeve (5) pulled over the barrel axially. This sleeve is provided with gas diverting channels. The transverse hole in the barrel are arranged close to the cartridge chamber and the muzzle region. The sleeve has radial diverting channels connection to axial channels (7) within the sleeve bore. The sleeve is also rotated by an external lever (6) for aligning gas diverting holes.

Title: Rapidly varying gas temp. measurement - involves excitation by electromagnetic radiation and monitoring radiation of gas
Inventor: GEISSELMANN HERIBERT
IPC: G01J5/00
Filed: 1975-10-04
Abstract: Atoms in the gas are excited from original ground state (O) to an excited state by irradiation by an electromagnetic radiation. Temperature dependent changes from this state to higher excitation states are amplified, and radiation so generated is measured and the temperature of the gas may be calculated from it. The apparatus measures the temperature of the small volume of gas which lies at the intersection between the directions of irradiation and observation. The system may monitor emissions of sodium light. It may be used for measuring temperature of electric arcs and flames.

Title: Engine fuel feed system - employs fuel catchment rings on inlet ports to divert rich mixture direct to ignition zone
Inventor: LANGE KARLHEINZ DIPL ING DR
IPC: F02B17/00
Filed: 1975-11-19
Abstract: A stratified engine fuel feed system has a ring insert (5) at the cylinder head (1) inlet port (2) opening at its junction with the inlet manifold. The ring has a collecting channel (6) with its lowest point joining a hole (7) in the inlet port leading directly to the inlet valve (3) as close as practical to the ignition electrodes (9). Fuel precipitation collects in the collecting channel and flows via the hole to the spark electrodes to form a rich mixture in that region. The remaining combustion chamber receives a correspondingly weakened mixture. A stratified fuel charge effect is gained to give improved engine performance and a reduced harmful exhaust emission.

Title: Fuel reforming system for IC engines - hydrocarbon based fuels are reformed by compression or partial oxidisation
Inventor: ARIGA HAJIME
IPC: F02M27/02
Filed: 1976-04-29
Abstract: A conventional internal combustion engine is provided with a fuel reformer unit to transform a hydro carbon based fuel into a reformed gas with a high H2 and CO content. The engine (10) is fed with a mixture of air (60), reformed gas (50) and an additional fuel supply (80) for full load. The air fuel ratio is 1 ; 0.6 so that the fuel is only partly oxidised in the reformer. A final air fuel ratio of approximately 4 ; 1 is fed to the engine. Alternative fuel reformers use the engine exhaust heat in a heat exchanger system in order to accelerate the reforming process. A third alternative uses a number of the engines cylinders as compressors for the reforming process as well as the exhaust gas heat exchange.

Title: Regulation of driving shafts of ships - using pulse generators to ascertain differential number of revolutions and differential positioning angle of at least 2 shafts
Inventor: WORTMANN RAINER
IPC: H02P5/56
Filed: 1976-05-11
