Title: Protecting gas or liq. delivery system against dry running -  using light transmitted via transparent walls to receiver only if without medium
Inventor: AUCHTER BRUNO DIPL ING
IPC: F04D15/02
Filed: 1990-09-12
Abstract: A method, protecting a delivery mechanism with a pipe for liquid or gas, and esp. with a circular pump for liquid, against dry operation, involves passing light through a pipe section with transparent wall sections or walls. After multiple refraction in two walls of an empty pipe section the light reaches a receiver and triggers a signal. However, if the pipe section is filled with the medium then the light does not reach the receiver. USE/ADVANTAGE - Ensures reliable indication of whether pipe section is full or empty under practically all conditions.
Patent DE-4033408-A1 (DE)
Inventor: BOLLER PETER
IPC: H04N5/76
Filed: 1990-10-20
Abstract: In the programming of video recorders for the automatic recording of television transmissions by means of bar-code readers, misprogrammings can occur if video recorders without video programme system decoders (VPS decoders) are used together with the bar-code reader since the bar-code information contains the VPS start and stop times. This problem is solved by the invention in that the bar-code reader is provided with a possibility for setting whether a video recorder with or without VPS decoder is to be programmed so that, if necessary, instead of the VPS start and stop time, the current start and stop time additionally contained in the bar-code information can be forwarded to the video recorder. Device for programming video recorders.

Patent DE-4039319-A1 (DE)
Inventor: KOSLOWSKI THOMAS DR
IPC: C04B38/10
Filed: 1990-12-10
Abstract: A process for producing lightweight, panel or block-shaped gypsum building materials with a pore structure, in particular wall panels, wherein calcium sulphate alpha-hemihydrate, water in a slightly more than stoichiometric quantity, setting retarders and/or accelerators and additives are mixed to form a pourable suspension and subjected to suitable forming.

Patent DE-4040102-A1 (DE)
Title: Sliver comber - has airflow to draw material into the clothing for more intense action and slower comb speed
Inventor: STAHLECKER FRITZ
IPC: D01H4/30
Filed: 1990-12-16
Abstract: Appts. to spin a yarn from a sliver feed, where the fibre tufts are combed at high speed through a needle or toothed clothing and the combed fibres are accelerated into a twisting zone, has an air generating system to move air at the combing zone to the surface of the combing units to flow past the sliver end and draw it into the clothing. Pref. the combing unit is perforated, and the air flow through it is induced by a suction system, while a blowing air stream is generated at the combing zone directed at the combing zone and through the clothing. The blown air stream is produced by a rotating roller with a number of slit openings to blow air in the direction of clothing and comb movement. The blown air openings are at an angle in the direction of roller rotation. Air is also generated to carry the fibres to the collection point, at the transfer zone, from within the comb towards the collection stage. The comb is a roller with a clothing round its circumference, or it is a disc with ring-shaped clothing on one side. The feed has an entry funnel to feed and combine a number of slivers at the same time. ADVANTAGE - The assembly gives a steady acceleration to the fibre material, from the sliver feed to the yarn take-off, without excessive yarn take-off speeds. The suction action on the sliver gives a thorough combing action on the fibres, throughout their path, which allows the combing roller speed to be reduced by about 50% of other equipments.

Title: Program switch for washing machines - with lockable pre-selection and rotary cam block with set program cams
Inventor: GERINIERE PIERRE
IPC: H01H43/10
Filed: 1991-02-14
Abstract: A washing machine program switch incorporates a lockable pre-selection system and a rotary cam block comprising a set of programm cams.

ADVANTAGE - The cam block can be guided manually and directly into every desired angle position without the help of an electric rotating drive.

IPC: B60G17/04
Filed: 1991-05-10
Abstract: The suspension of the steering axle of a motor vehicle, especially of an agricultural or industrial vehicle, contains a spring device arranged between vehicle superstructure (28) and axle beam (12, 14). In order to permit a ride height compensation of the vehicle body for different axle loads or tyre combinations, at least one pivotably fixed hydraulic cylinder unit (62) is arranged between vehicle superstructure (28) and axle beam (12, 14), which unit contains a first hydraulic cylinder (68) which is arranged so that it functions in series with the spring device between the vehicle superstructure (28) and the axle beam (12, 14) and can be connected by way of a hydraulic valve (112) to a pressure source (114). A second hydraulic cylinder (70) may be arranged so that it functions in parallel with the spring device in order to influence its spring characteristics and to permit fixing of the suspension. The vehicle superstructure (28) and the axle beam (12, 14) are preferably connected to one another by at least two oscillating links (30, 32) of approximately equal length and running essentially parallel. The oscillating links (30, 32) are pivotably fixed on the vehicle superstructure (28) on the one hand and on the axle beam (12, 14) on the other to form an oscillation parallelogram and only permit an essentially translatory relative movement between vehicle superstructure (28) and axle beam (12, 14). <IMAGE>
Patent DE-4117098-A1 (DE)
Title: Master cylinder for ABS brackets
Inventor: BURGDORF JOCHEN
IPC: B60T8/38
Filed: 1991-05-25
Abstract: The hydraulic ABS brakes have a master cylinder with an actuating piston which is connected to as central valve inner housing (6), in which two valves (35,44,37,40) are fitted. The first valve (35,44) consists of a ball (44), which cooperates with a seat (35), whilst the second valve conssits of a rubber ring (40) which cooperates with a seat (37).     The first valve normally controls the flow between the two chambers of the master cylinder, but in the event of the first valve failing to close because of particles of grit between the ball and the seat, the second valve (37,40) can be closed by further travel of a support (38) under the force of a spring (49).
Patent DE-4121570-A1 (DE)
Inventor: HEIDEMANN ROLF DR
IPC: H04B10/2513
Filed: 1991-06-29
Abstract: To be able to compensate for the non-linear signal distortions occurring due to the "laser chirp" and the chromatic dispersion of the optical waveguide in analog optical transmission systems, an equaliser in the form of an LC section is known, the capacitance of which is formed by a capacitance diode. However, the known equaliser only functions when the capacitance has the suitable polarisation which cannot be predicted because of possible polarity reversal during the signal transmission. According to the invention, a further capacitance diode (Cb) is connected in parallel with the capacitance diode (Ca), with opposite polarisation, and is also biased in the reverse direction. By setting the bias voltage of the two capacitances, it can be achieved that optionally one of the two capacitance diodes handles the equalisation function and the other one is virtually ineffective. Further developments of this solution relate to keeping the frequency response constant during the adjustment of the equaliser, by means of a controllable capacitance connected in parallel with the capacitance diodes (Ca, Cb), and the equalisation of signals with large bandwidth by a cascaded LC circuit with LC sections according to the invention.   <IMAGE>

IPC: E05F15/646
Filed: 1991-10-07
Abstract: A device for moving a swinging and sliding door in a mass-transit car, especially a car that travels along a track. Each panel of the door slides lengthwise along a guide element. The guide element moves as part of a four-point articulation across the plane of the panel. The lengthwise motion of the leaf is coordinated with its transverse motion by a rail. The rail is fastened to the doorframe. Guide means are fastened to the panel and engage the rail. A drive mechanism on the panel directs force toward the guide element. As the drive mechanism (20-22, 30 & 31, or 40 & 4n1) reacts it exerts torque on an expansion element (25, 35, or 45) between the guide element (3) and a supporting component (25.2, 35.2, or 45.2) attached to the doorframe (16). The torque produces a force substantially normal to the guide element. The force generates the transverse motion.
