Title: Optical coupler
Inventor: KOENIGSDORFER WALTER
IPC: G02B6/38
Filed: 1992-12-17
Abstract: To transmit information via light wave guides (8, 8`), optical couplers with two separate coupling components (A, A`), each having a coupling housing (1, 1`) are used. The optical separation plane is securely sealed against any pollution.The light beams coming out of the wave guide (8) to the right are diverged through a beam diverger (9). They are deflected by two prisms (10, 10`) and are converged by a beam converger (9`) into the cross section of a wave guide (8`). To split the beams, the two coupling housings (1, 1`) are pushed together in the axial direction. Spring biased plungers (13, 13`) push surfaces of the prisms (10, 10`) and seal them against dust. The plungers (13, 13`9) can have sealing lips (18, 18`) and a channel for guiding a cleaning fluid. Mirrors can be used instead of prisms.

Title: Method for the generation of electrical energy
Inventor: SCHWIEGER JOACHIM DIPL ING
IPC: F02C1/10
Filed: 1993-02-04
Abstract: The invention relates to a method and an installation for the generation of electrical energy by burning preferably gaseous, fossil fuels with pure oxygen. For this purpose a closed cycle with at least one combustion chamber, a gas turbine, a waste heat boiler serving for preheating and compressors for compression of the working medium to combustion chamber pressure are provided, an inert gas being used in the cycle as working medium. Carbon dioxide is preferably used as working medium and natural gas as fuel. After the working medium still charged with the products of combustion has left the gas turbine and after the heat still present in the expanded working medium has been released in one or more heat exchangers, the products of combustion are drawn off from the cycle by suitable measures. The residual heat is abstracted from the working medium by coolers and used as process heat or for district heating systems.

Title: Spring arrangement on a damping cylinder
Inventor: ROEMER LUTZ
IPC: F16F9/58
Filed: 1993-03-10
Abstract: Spring arrangement on a damping (shock-absorber) cylinder (1) which has, in a cylinder casing (3), an axially displaceable damping piston and a piston rod (2) which projects outwards from the latter and is connected in the projecting region to a stop part (4) against which the cylinder casing (3) is supported via a spring (6, 7) in the case of relatively large contractions of the damping cylinder (1). The visible outer region of the piston rod (2) is surrounded by a piston-rod protector (7) of variable length in the axial direction which is supported, if required via a spacer, against the cylinder casing (3), on the one hand, and against the stop part (4) on the other. The piston-rod protector (7) has elastic wall regions which rest against one another axially beyond a predetermined contraction of the damping cylinder (1) and, when the damping cylinder (1) contracts further, produce an elastic force which counteracts the contraction of the damping cylinder (1). <IMAGE>
Patent DE-4311415-A1 (DE)
Title: Anti-insect roller-grille device with cleaning brush
Inventor: WILDT ADOLF
IPC: E06B9/17
Filed: 1993-04-07
Abstract: In order to prevent the gauze of the anti-insect roller-grille device from being soiled by undesired particles such as dust and gradually losing its translucence, there is fitted, in the region of the run-out edge of the roller-blind casing, a brush strip which extends over the entire width of the gauze and rests thereon. Each time the gauze is moved downwards and upwards, said gauze is automatically freed of adhering undesired particles. Moreover, the brush strip forms an effective barrier against insects which try to pass from the interior of the roller-blind casing behind the gauze through the window opening or door opening. A further advantage of the brush strip consists in the fact that it closes off a cold bridge to the roller-blind casing.

Title: Bulldozer blade arrangement
Inventor: ASAL JERROLD R
IPC: E02F3/85
Filed: 1994-09-26
Abstract: In many applications it is desirable to have a bulldozer blade arrangement which can be angled and/or tilted without elements of the bulldozer blade arrangement coming into conflict with the machine to which it is attached. In the present arrangement, a bulldozer blade arrangement has a bulldozer blade which is connected to a U-shaped frame via a universal joint. The bulldozer blade is angled by a pair of angling cylinders which are connected between the U-shaped frame and a pair of spaced-apart angling-cylinder straps arranged on the bulldozer blade. The universal joint is connected to the bulldozer blade generally in the centre between the pair of spaced-apart angling-cylinder straps and is generally in alignment with them. The inclination of the bulldozer blade is held at a preselected position by an inclination control mechanism and is set mechanically by the inclination control mechanism. Since the pair of spaced-apart angling-cylinder straps and the universal-joint connecting strap are generally in transversely running orientation and since the universal-joint connecting strap is generally arranged in between in the centre, any tilting of the bulldozer blade allows the connecting points of the pair of angling cylinders to remain generally along their neutral axis. The present arrangement enables the bulldozer blade to be angled and tilted without elements of the ... Original abstract incomplete.
