Patent DE-3821938-A1 (DE)
Title: Method and device for digitally determining a number proportional to the rotational speed of a body
Inventor: REINERS DIETER DIPL ING
IPC: G01P3/489
Filed: 1988-06-29
Abstract: The subject-matter of the invention is a method for determining a number which is proportional to the rotational speed of a body. An angulometer (angle transmitter) is used to carry out a time measurement by counting periods of a reference oscillation. In the event of changes in the angular position of the body, the value of the angular position is updated and stored. The time value present at the instant of the change is stored. The stored angular position value is read out. The stored time value is subtracted in time intervals given by a constant interrupt interval from the angular position value read out in the respective preceding interrupt interval. This is also performed with the time values. The difference in the angular position values is divided by the difference in the time values and multiplied by a constant. The number of the periods of the local reference oscillation which occur within a global time interval generated by a central time base is recorded. A correction factor for the rotational speed measurement is determined from the ratio of this recorded number to a predetermined number. <IMAGE>
Patent DE-3822711-A1 (DE)
Title: Cable deflection device
Inventor: ENZINGER HANS DIPL ING
IPC: H02G11/00
Filed: 1988-07-05
Abstract: If, for example in the case of a carriage which can be moved to and fro along a track, cables are deflected in a cable track, the problem arises that, at the exit point of the carriage, the cable is as a rule bent alternately in the opposite direction on each crossing of the fixed point of the cable. This leads to considerable stress on the cable, which can ultimately lead to damaging of the cable. In order to ensure non-harmful deflection for this case, a cable deflection device is provided which includes in the carriage (1) a twisting section (39) which runs transversely to the direction (33) of travel and in which, depending on the position of the carriage (1) with respect to the fixed point of the cable in a cable track (3), the cable clamped in the carriage (1) is twisted. Subsequently thereto, an unchanged cable-curvature section is moved only from one pivoted position to the other, opposite pivoted position, without the cable being stressed at the cable-curvature section. The cable deflection device is suitable above all for movable carriages, equipment parts, etc. <IMAGE>

Title: Electrically driven hand screwing device
Inventor: SCHMIDT ALFRED DIPL ING
IPC: B25B23/147
Filed: 1988-07-07
Abstract: When working with electrically driven hand screwing devices, it repeatedly occurs that a screwing cycle does not run correctly. This can be caused by a premature termination of the screwing operation, inadequate adhesion between screw and object to be screwed, an incorrect voltage supply or the like. Such a case is to be indicated promptly to the user in order to avoid any damage which might result.   For this purpose, the hand screwing device is equipped with a circuit arrangement for monitoring the correct progress of the screwing operation, which is activated by the switch which can be actuated by the coupling and triggers an acoustic and/or visual warning signal in the event of a prematurely ended screwing operation, insufficient or no longer sufficient power for the drive motor and also inadequate adhesion between screw and object to be screwed (Fig. 1). <IMAGE>
Patent DE-3827031-A1 (DE)
Title: Loading cylinder with a hollow piston rod
Inventor: ZUBER GUENTER
IPC: F15B15/14
Filed: 1988-08-10
Abstract: A loading cylinder with a cylinder housing having pressure-medium connections and cylinder caps and a piston having a hollow piston rod led to the outside through one cylinder cap is to permit high piston speeds, is to have low moving masses and is to effectively dampen the piston movement at the end of the piston travel. This is achieved in that a piston element (6) is arranged in the hollow piston rod (3), which piston element (6) bears in a sealing manner against the inner wall (8) of the hollow piston rod (3), that the piston element (6) is firmly connected to the second cylinder cap (5') by a rod (7) guided and sealed off by the piston (2), that the hollow piston rod (3) is arranged on the piston (2) in such a way that two cylinder spaces (10a, 10b) are formed between it and the cylinder inner wall (1a) or the rod (7) guided by the piston (2), and that the two cylinder spaces are connected to one another by openings or bores (9) arranged near the piston (2) in the hollow piston rod (3). A loading cylinder of this type can be used in particular as a quick-breaking or catapult cylinder. <IMAGE>
Patent DE-3827486-A1 (DE)
Title: Process and apparatus for producing extensibly stable, liquid-impermeable, flexible pressing belts, in particular for wet presses of paper machines
Inventor: JOOS HEINZ
IPC: B29D29/00
Filed: 1988-08-12
Abstract: The strength, in particular the tensile strength, of such pressing belts has to meet high requirements, which until now had to be satisfied by producing the reinforcing fabric belt, onto which a flowable mixture of a prepolymer was poured in order to create a smooth or textured surface on the surface of the belt, at least partially from high-tenacity yarns, which however could only be controlled with great difficulty during weaving, for which reasons certain high-strength materials could not be used at all. The invention avoids this disadvantage by introducing single-strand or multi-strand reinforcing yarns, and/or reinforcing yarns in the form of tapes, into the coating composition during the coating of the reinforcing fabric belt with the prepolymer mixture at the same time as the coating composition and, as a result, building these up on the surface of the reinforcing fabric belt. <IMAGE>
Patent DE-3838999-A1 (DE)
Inventor: KORN HEINRICH
IPC: A47C1/032
Filed: 1988-11-18
Abstract: The invention relates to a chair, in particular a work or office chair, having a seat (16), which can be swivelled in the front region about a horizontal swivel axis (12) and can be altered in inclination, and having a backrest (15), which can be altered inevitably overproportionally in inclination in dependence on the alteration of the inclination of the seat, in which, with increasing inclination of the seat, the backrest executes an additional relative movement in relation to the end of the seat facing it, in which swivel levers (13) are attached on both sides of the seat on supporting arms of the seat frame, the free ends of which swivel levers are mounted fixedly and non-rotatably on the backrest (15) and support the latter, and in which the seat (16) is connected rotatably in its central region to the swivel levers (13). The desired relative movements between the seat, the backrest and the chair frame can only be implemented and varied by the coupling between the seat, the backrest, swivel levers constructed as arm supports or armrests and the chair frame by the fact that, in the region of its front edge offset upwards in relation to the attachment axis of the swivel levers, the seat is mounted rotatably on extensions of the supporting arms so as to be non- adjustable or limitedly adjustable, and that the axis of rotation between the swivel levers and the seat is limitedly adjustable or non- adjustable. <IMAGE>
Patent DE-3907664-A1 (DE)
Inventor: YOSHIMURA KATSUJI
IPC: G01S3/786
Filed: 1989-03-09
Abstract: An image sensing apparatus, e.g. for an autofocus video camera, operates with adaptive selection of a first tracking algorithm in which an image is tracked by moving a detecting area capable of being movably set on an image sensing plane in such a manner that the luminace lever difference between the inside and the outside of that area becomes maximum and a second tracking algorithm in which the object image is tracked by moving the position of the detecting area in such a manner that a point at which a contrast becomes maximum comes to coincide with a central portion of the detecting area. The threshold values for changing over between the first tracking algorithm and the second tracking algorithm are made to have a hysteresis characteristic.

Patent DE-3917832-A1 (DE)
Inventor: HAMISCH HANSJOACHIM DR
IPC: G01P9/04
Filed: 1989-06-01
Abstract: A sensor (10) for determining angular velocity ( OMEGA ) comprises a piezoelectric shearing oscillator (12) which functions as an emitter. Ultrasonic waves generated by the oscillator travel along a sound conductor to two receivers (14, 15) separated by a small gap (16) which are located at the other end. When the sensor detects an angular velocity ( OMEGA ), the ultrasonic waves reaching the gap (16) should excite the two receivers with equal intensity, so that the differential signal of the two receivers (14, 15) boosted by a compensation is equal to zero. If the sensor (10) is located in a rotating system, the ultrasonic beam is deflected by the Coriolis force (K &cir&  NOt c) so that a differential signal which is a measure of the angular velocity ( OMEGA ) is obtained from both receivers (14, 15). The sensor (10) is simple, mechanically stable and virtually unaffected by vibrations and temperature.
