Patent DE-4215871-A1 (DE)
Title: Michelson interferometer for Fourier transform spectrometry - has transparent plate mounted on rotary shaft at angle to normal and supporting opposing ring-shaped mirror surfaces between which beam is reflected from and to divider-combiner in opposite directions.
Inventor: SCHNEIDER KLAUS
IPC: G01J3/453
Filed: 1992-05-14
Abstract: First and second spaced opposing mirror surfaces (40a,41a) are provided as a reflector element (4). The first surface (40a) nearest to the beam divider (1) is in the form of a concentric or elliptical ring. The second surface (41a) is circular or elliptical. The rotary axis (51) of a drive shaft (5) is aligned with the same plane of the beam divider. An acute angle ( alpha ) is enclosed between a normal to the rotary axis (51) and the second mirror surface (41a). Two plane mirrors (61,62) are located on opposite sides of the rotary axis (51) and perpendicular to a beam from the divider (1). The two halves of a beam impinging on the beam divider diverge onto the centrally arranged mirror surface, and are directed from this to the opposing ring shaped mirror surface, and reflected from there to the two plane mirrors (61,62). The beam is reflected from the plane mirrors in the reverse direction, recombined at the beam divider and by means of the collecting lens (2), the beam is focused on the detector (3). ADVANTAGE - Compact, gives high spectral resolution at small cost. Influence of interference sources is reduced.

Title: Coiled filter body - has a layer with better drainage structured with denser zones across the wood direction
Inventor: BREITBACH PETER P
IPC: B01D29/11
Filed: 1992-05-23
Abstract: The filter structure of a deep fitler body, which can be back rinsed, is composed of at least two non-woven layers with different drainage characteristics, wound in a coil. the layer with better drainage has at least one zone of a denser material across the wound direction, for reduced permeability by the fluid passing at a tangent in the layer with better drainage compated to the radially neighbouring layer. Also claimed is a mfg. process where the layer with the better drainage, before winding into a coiled filter body or during winding, is continuously compressed along a zone to give reduce permeability within limits. USE/ADVANTAGE - The filter body is a wound coil of material which can be back rinsed and cleaned, and gives a deep filter action. The filter gives an effective filtering action, which retains the filtered matter without the fluid passing by the layers. It is easily cleaned and is made cost-effectively.

Patent DE-4235948-A1 (DE)
Inventor: BRAUN HERMANN
IPC: F02M61/18
Filed: 1992-10-23
Abstract: A fuel injection nozzle (1) for internal combustion engines has injection holes (4) with a continuously variable cross-section. The injection cross-section can be continuously varied by means of two adjustable components (2, 3) of the nozzle body located opposite each other and which together delimit the injection holes (4). The adjustment mechanism is independent from the movement of the nozzle needle (5). Consequently, the back-and-forth movement of the nozzle needle (5) and the adjustment of the injection cross-section do not affect each other. The adjusted position can be maintained for the whole duration of the injection. The jet can thus be formed without disturbances during the whole injection process. An easy-to-manufacture design of the nozzle body consists of components (2, 3) whose angular position can be adjusted with respect to each other and which have sawtoothshaped circumferential surfaces which rest upon each other.

Patent DE-4332118-A1 (DE)
Title: Fuel injection device
Inventor: GMELIN KARL DIPL ING
IPC: F02M51/08
Filed: 1993-09-22
Abstract: For the contacting of solenoid fuel injection valves it is usual to contact the connection elements of the fuel injection valve with a crown-shaped connector housing. When attaching the connector housing to the fuel injection valve, however, the problem arises that, due to tilting as a result of inadequate axial centring of the connection elements, the latter are bent, so that in the worst case the fuel injection valve does not make electrical contact. For reliable contacting of a fuel injection valve (2) the said valve has a guide pin (50), which with its free end (51) projects beyond free ends (42) of the connection elements (40), so that before the introduction of the connection elements (40) into corresponding connector sockets (60) the said pin slides in a guide opening (61) in order to centre the connection elements (40) of the fuel injection valve (2). The invention is intended for the contacting of solenoid fuel injection valves for fuel injection devices. <IMAGE>
