Title: Device for cutting several optical waveguide fibres
Inventor: KALWEIT HANS-ULRICH DIPL ING
IPC: G02B6/25
Filed: 1985-08-02
Abstract: A simple, easy-to-handle device for cutting several optical waveguide fibres (1) which are inserted at the envisaged cutting point in parallel grooves on a support (5), the optical waveguide fibres (1) being held by at least two clamp devices (3, 4, 6) arranged on each side of the envisaged cutting point, one clamp device (3, 4) being mounted in a stationary fashion and the other (6) being mounted in such a way that it can be moved away from the cutting point, and a blade (8) which can be displaced perpendicularly to the axes of the optical waveguide fibres being present, which blade (8) slightly cuts into the optical waveguide fibres (1) at the envisaged cutting point, consists in the fact that the optical waveguide fibres (1) to be cut are clamped tight on a carrier (2) which is detachably connected to the cutting device and that either this carrier (2) or the support (5) which holds the optical waveguides (1) and on which the optical waveguide fibres (1) are slightly cut with the blade (8) is mounted so as to be displaceable in the axial direction of the optical waveguide fibres (1). <IMAGE>
Patent DE-3529078-A1 (DE)
Title: Transmitter amplifier with selective noise feedback
Inventor: LINDENMEIER HEINZ PROF DR ING
IPC: H03F1/34
Filed: 1985-08-14
Abstract: The invention relates to an additional circuit (2) for high-power broadband transmitter amplifier stages which forms a feedback arm to the transmitter amplifier stage (1) and whose input is connected to the output of the transmitter amplifier stage, as shown in Fig. 1. The additional circuit (2), as shown in Fig. 2, contains a filter circuit (7) which suppresses the useful signal (3) of the transmitter in frequency-selective fashion and through which the noise signal (4) can pass in the vicinity of the frequency at which the transmitter noise is reduced. The output noise signal (5) of the filter is added to the input of the transmitter amplifier stage in a summing circuit (6) at this frequency through negative feedback and the frequency dependence on amplitude and phase response in the additional circuit is designed in such a way that self-excitation of the circuit is prevented and adequate suppression of the transmitter noise occurs in the vicinity of the desired frequency. The transmitter noise is thus suppressed in frequency-selective fashion without the use of frequency-selective circuits in the power arm of the transmitter amplifier. Thanks to the small size of the signals in the frequency-selective parts of the additional circuit, the latter can be designed even for extremely short tuning times. <IMAGE>

Patent DE-3609414-A1 (DE)
Title: Guide bolt
Inventor: MAYERL HELMUT
IPC: B60J1/17
Filed: 1986-03-20
Abstract: The invention relates to a guide bolt for movable vehicle windows, with a fastening part which is connected in one piece via a spacer to a disc-shaped head part, the head part forming, with a moulded-on plastic covering, a guide part which has an outwardly open depression with radial engagement surfaces for a turning tool. In the case of known guide bolts, there is provided on the front end of the head part a cylindrical projection which extends up to the free surface of the plastic covering. The depression, which has a shape similar to a hexagon socket, is pressed into the projection, this being complex in terms of production and leading to the disadvantage that stress cracks may appear on the rear front end of the head part in the transition to the spacer. According to the invention, in contrast it is provided that the plastic covering surrounds, for rotation in common, the head part with a positive engagement which is effective essentially in the direction of rotation around the longitudinal axis of the guide bolt, and that the depression is formed in the plastic covering itself.

Patent DE-3628626-A1 (DE)
Title: Propeller windmill with expanded field of application
Inventor: FRIEDEN PETER DIPL ING
IPC: F03D7/02
Filed: 1986-08-22
Abstract: A rotor concept for wind-energy converters with a quick-reaction, simple mechanical variable-pitch mechanism is presented. Due to the special position of the pitch-control axle in conjunction with a special spring-joint mechanism, the variable-pitch mechanism responds equally to air and centrifugal forces, enabling operation at constant output and r.p.m. at all wind speeds above the rated wind speed. Besides an effective speed limitation, this arrangement also decreases the structural loads above the rated wind speed, making an extremely light and inexpensive construction possible. This invention allows optimum matching of the driven machine (generator, heat-pump compressor, etc.) to the particular wind conditions, and reliable overload protection to be achieved in an ideal fashion.

Title: Conveying device for conveying and depositing workpieces which are easily damaged during handling
IPC: B65G47/94
Filed: 1986-09-29
Abstract: Conveyor belt units (21, 22) are arranged on an apparatus frame (20) of a deposition unit for workpieces (3) which are easily damaged during handling, the conveyor belts (23, 24) of the said units each being inclined at an angle of 45 DEG  to one another and being arranged symmetrically about a vertical central plane (25). The lateral surface of the lower edge of the upper run (231) is situated on the top of the lateral run of the upper run (241). Both conveyor belt assemblies are connected to a common drive, perhaps via universal joints (27, 271) and belts (28, 281). The conveyor belt unit (22) can, for example, be moved approximately horizontally out of the indicated conveying position by actuation of a compressed-air cylinder. In this process, a floor aperture (31) is formed from the floor seal (29) of the angular conveying trough (30), through which aperture (31) the workpiece (3) can drop onto the transverse conveying belt (8) and is conveyed onwards by the latter. A layer of plastic on the conveyor belt (8) reduces the impact. The workpieces (3) may be formed by means of transverse division of, for instance, extruded tubes, profiled rods and the like made of plastic, but also of wires, cables or cable casings, or bodies of any shape at all. They can then be conveyed onwards and deposited even if the material of which they are made has not yet hardened. The conveyor belts (22, 23) are stopped to permit transverse division and deposition. <IMAGE>

Title: Oil-cooled piston with a combustion recess for an internal combustion engine
Inventor: DEUTSCHMANN HERBERT
IPC: F02B75/04
Filed: 1986-10-31
Abstract: A piston with a combustion recess comprises three parts: an oil-cooled piston ring carrier (11), an adjusting body (13), forming the base of the combustion space recess, and a piston lower section (14). The axially adjustable adjusting body (13) arranged in a bore (34) of the piston ring carrier (11) has a collar (21) on its side remote from the combustion space which, interacting with a corresponding recess in the piston ring carrier (11), forms an annular first chamber (22). Between that face of the adjusting body (13), remote from the combustion space, and the piston lower section (14), another chamber (23) is formed. Both chambers (22, 23) are supplied with oil from the piston cooling oil system and, in conjunction with non-return valves (31, 33), produce an automatic hydraulic adjusting system for the adjusting body (13). The arrangement gives a simple, mechanical construction of the adjusting device and enables the adjusting body (13) to be fitted even in a piston which has a combustion space recess (12) with necked recess edge (35). <IMAGE>

Title: Process for the preparation of anhydrous synthetic silicon dioxide
Inventor: BRUENING ROLF DIPL CHEM DR RER
IPC: C03B8/04
Filed: 1987-02-03
Abstract: The invention relates to a process for the preparation of anhydrous synthetic silicon dioxide by thermal oxidation of a silicon compound using oxygen in the gas phase, which process enables the economic production of OH-free high-purity, specifically doped quartz glass. It is proposed to heat at least the oxygen to the reaction temperature by the external action of heat, to carry out the oxidation of the silicon compound in a reaction space isolated from the external atmosphere and to cool amorphous silicon dioxide formed during the oxidation and to deposit it in wet form outside the reaction space. The amorphous silicon dioxide is shaped in the moist state, subsequently dried, sintered and melted in a conventional manner to give quartz glass. The silicon compound employed is a rectifiable silicon halide comprising silicon and chlorine and optionally oxygen. The liquid used for the wet deposition is one of the reactants. Oxygen is passed in countercurrent to the silicon dioxide. Chlorine is recovered quantitatively in elemental form.
