Patent DE-3045572-A1 (DE)
Title: Automatic system for bus door pneumatic drive - has door control valve actuator operated by pushbuttons via control logic circuit
Inventor: STRANGFELD RALF DIPL ING
IPC: E05F15/02
Filed: 1980-11-28
Abstract: The automatic system has a logic control for the door valve, operating on commands from both the passengers and the driver. The valve enables door closing after a defined opening period. An output voltage of a door valve switching transistor feeds several feedback paths, some affecting the control circuit of a driver stage transistor, governing the door valve transistor. One feedback path alone defines a min. pulse length for the door valve transistor even at the shortest possible energising of this transistor. Another feedback path energises a holding position retarding thyristor. The system is suitable for combined application with the driver's push-button for manual tripping, is effected directly but across parts of the control logic circuit.

Title: Pick for earth cutter - has tip for use on leading edge with additional tips behind and covered with soft material
Inventor: REYNOLDS JOHN MICHAEL
IPC: E21C35/183
Filed: 1980-12-11
Abstract: The cutter pick for use in earth cutting apparatus has one cutting tip (2) exposed ready for use on a leading edge (4) of the pick body (1). One or more additional cutting tips (3) are also located in the leading edge though spaced from the first cutting tip and each other. Preferably these additional cutting tips are protected by a layer (9) of material softer than the tips. Thus, as the first cutting tip is worn away, the pick body wears away to expose the next tip, so extending the pick life.

Title: Resolver rotor angular position digital display circuit - achieves reduced errors using ROM contg. stored sine-cosine table
Inventor: GOTTSCHLICH MANFRED ING GRAD
IPC: H03M1/00
Filed: 1980-12-20
Abstract: The circuit for digitally indicating the angular position of a resolver rotor is for resolvers with stator windings having two poles at 90 degrees to each other. An a.c. supply contg. a pulse generator and digital-to-analogue converter supplies the stator windings with equal frequency and amplitude a.c. voltages mutually phase shifted to 90 degrees. The pulse generator drives a counter producing a clock signal whose frequency is a multiple of the supply frequency. The counter contents are transferred to a hold register dependent on the amplitude of the rotor winding signal. Measurement errors are kept distinctly lower than with the circuit after DE-AS 27 32 024. This is achieved by using a ROM in front of the digital-to analogue converter contg. a quadrant or more of a sine-cosine table addressed by the counter.

Locking members (14,15) allow the sliding portion to be secured in an initial position corresponding to the sitting position of the patient with the backrest rfree of stress.
Patent DE-3049300-A1 (DE)
Title: Continuous universal beam rolling - using leading ends of blanks pointed at specified angles
Inventor: SILOV VLADISLAV A
IPC: B21B1/08
Filed: 1980-12-29
Abstract: In a continuous rolling of universal beams the leading end of a blank is sharpened on both sides before it is reduced in the splitting and beam forming passes. The recommended angles relative to the centre line of a blank are 25 to 35 deg. An additional sharpening of the sides of the leading edge of a blank can be employed. This method prevents delamination of the leading end and encirclement of the rolls by the blank. It facilitates the entry into the roll gap by the artificial tongue on the leading end.

Title: Device for distinguishing aircraft flying overhead
Inventor: KUEBLBECK HERMANN DIPL PHYS
IPC: G01H3/00
Filed: 1981-01-22
Abstract: This device is used for distinguishing between aircraft flying overhead and rolling or starting aircraft. This is intended to prevent unwanted ignition of weapons, for example ground mines, in the case of aircraft flying overhead. The device has a sound pickup and bandpass filters which are tuned to characteristic frequency bands. To prevent false firings reliably in a simple manner, it is proposed that a sound pickup supplies input signals for two bandpass filters (2, 3), one of which is a high-pass and the other a low-pass filter. The bandpass filters form mean or RMS values (TP, HP) of the signal components and these values are first divided by one another in a device (6), a quotient Q  APPROX  HP DIVIDED TP being formed. It is then found whether the quotient Q is above a critical value in which case a signal preventing the triggering of the weapon is given.   <IMAGE>

Title: Switching device for the independent triggering of a plurality of adjustment devices arranged in or on a motor vehicle
Inventor: FEIN BERTHOLD
IPC: B60R1/07
Filed: 1981-05-06
Abstract: The switching device according to the invention is provided for independently triggering the adjustment devices of two motor vehicle outside rear view mirrors in particular. Switching devices are known in which a switch for controlling the adjustment directions of adjustment devices is accommodated in a casing, which adjustment devices each have an actuating knob which can be moved into a plurality of switching positions according to the adjustment directions, although a second actuating knob must be used for changing over to control of the respective adjustment devices. In the case of the switching device according to the invention, the actuating knob (100) can in addition be changed over by means of a movement which deviates from the switching directions from a first position into a second position, it being possible for a first switch (30) to be operational in the first position of the actuating knob (100) and for a second switch (40) to be operational in the second position. This permits all the contacts to be established or broken and the changeover to individual switches to be carried out by means of a single actuating knob. <IMAGE>

Title: Method of filling in drainage pipes and a pipe anchor for carrying out the method
IPC: E02B11/00
Filed: 1981-05-09
Abstract: A method of filling in drainage pipes which have been laid under the bottom or in embankments of a canal reach before it is constructed as well as a pipe anchor for carrying out the method are described. After a connection is made with the drainage pipe from outside, a pipe anchor is pushed in through the connecting point up to the end of the drainage-pipe section to be filled in, a rope, before the pipe anchor is pushed in, being attached to the pipe anchor via an unwinding or sliding device in such a way that its two ends project from the connecting point in the end position of the pipe anchor. A flexible tube is then fastened to one end of the rope, and the tube is drawn in up to the end of the drainage-pipe section to be filled in, whereupon the filling material is fed into the drainage-pipe section. The pipe anchor consists of a body which is rounded off in a cigar shape at its front end and in the periphery of which two grooves running parallel to the longitudinal axis of the body are made diametrically opposite one another. The grooves serve to accommodate one blade each which can be swung out of the periphery of the body. The blades, which are under spring force, bite firmly into the drainage pipe so that, although the pipe anchor is pushed in, it cannot be pulled out of the drainage pipe again. The technical and financial outlay for filling in drainage pipes which have already been laid is substantially reduced by the invention. <IMAGE>
