Title: Gun using liquid fuel as propellant -  has sliding piston which pumps fuel into combustion chamber
Inventor: MAAG HANS-JUERGEN DIPL ING
IPC: F41A1/04
Filed: 1991-08-28
Abstract: The gun which uses the burning of a liquid fuel as a propellant, has a barrel with a combustion chamber (7) with the projectile (5) having an initial position immediately in front of the combustion chamber. The rear wall of the combustion chamber is formed by a stepped annular piston (8). The piston slides over a shaft which projects from the end wall of the barrel. A fuel reservoir (2) is formed behind the piston and is supplied with fuel through the passageway (1). When the fuel in the combustion chamber is ignited, the resulting rise in pressure propels the projectile out of the barrel and at the same time drives the piston (8) rearwards. This causes fuel to be driven from the reservoir through the radial gap between piston and shaft and into the reservoir to maintain combustion in the combustion chamber. USE/ADVANTAGE - Gun using liquid fuel with continuous combustion.

Patent DE-4208967-A1 (DE)
Inventor: NEGISHI KIYOSHI
IPC: G03G15/20
Filed: 1992-03-19
Abstract: A fixing device employed in an electrophotographic printer comprises a heated roller 11 for fusing a toner image carried on a recording medium. The roller 11 is heated to a predetermined temperature so that the fixing operation can be executed. While the roller 11 is being heated, its temperature is detected by a thermistor 15 and information concerning the rate of change of temperature of the roller is used (at least until the temperature reaches the level where the fixing operation can be executed) to provide an indication to an operator of the waiting time necessary before use. A display of the roller temperature can alternatively be given. The thermistor output is also used to control switching thyristor 14 and thus a heating lamp 11A in the roller 11. <IMAGE>

Title: Line-by-line optical beam deflection by rotating mirror - randomly selecting polygon faces for adjacent line scans in conjunction with modulation control memory read=out.
Inventor: ZELENKA THOMAS
IPC: H04N1/113
Filed: 1992-06-20

Title: Apparatus for cooling room air
Inventor: SCHMIDT FRIEDRICH HARALD
IPC: F24F1/01
Filed: 1993-02-05
Abstract: In an apparatus for cooling room air by means of a heat exchanger capable of being supplied with coolant and having induction nozzles for generating a secondary airstream to be cooled, the induction nozzles are arranged in front of a flow interceptor, so that the secondary airstream and at least part of the primary airstream are guided through the heat exchanger. The flow interceptor forms, with the heat exchanger, an incident-flow channel narrowing superproportionally in the flow direction, so that behind the heat exchanger a low-pulse cold-air flow is generated.

Patent DE-4323347-A1 (DE)
Title: Propulsion arrangement for ships
Inventor: PLAAS-LINK ANDREAS DR
IPC: B63H1/36
Filed: 1993-07-13
Abstract: Previous methods work via the high acceleration of relatively small water quantities via marine propellers. As a result, the accelerated water is also set in rotational motion. This leads to reductions in the efficiency. The novel arrangement is intended to moderately accelerate large water quantities mainly against the direction of travel and thus permit a high efficiency. A plate is moved in a duct in the hull below the water line and forces water through this duct. The movement of the plate can be effected by a simple translatory movement as can be produced by reciprocating engines without crankshafts. Very large water quantities can be accelerated by these slow plate movements. The efficiency of this propulsion arrangement is very high.
