Patent DE-4202557-A1 (DE)
Title: Measuring signal=to=noise ratio in sensor system with digital filter banks - separately measuring noise energy generated by system imperfections and quantifying distortion-free channel capacity
Inventor: GOECKLER HEINZ DR ING
IPC: G01R29/26
Filed: 1992-01-30
Abstract: The method of measuring the signal/noise ratio of satellite supported telecommunication sensor systems having identical digital filter arrays for the multiplexing and subsequent separation/analysis of frequency multiplexed transmissions employs three separate determinations. The three measurements, based on the distortion energy falling outside the input frequency spectrum embraced by the multichannel transmissions are applied to one channel only which is adopted as a model for the system. They comprise (a) the determination of noise resulting from signal chopping/rounding, (b) the noise supplement due to spectral overlap, (c) a derivation of the maximum distortion-free capacity of the channel. USE/ADVANTAGE - Can be applied at small cost to systems using beam-forming networks. Enables independent evaluation of noise distortion arising from principal sources and maximum channel capacity for distortion-free transmission.

Title: Method for determining the adhesion margin of vehicles
Inventor: ANDREWS MARK
IPC: B60R16/02
Filed: 1993-05-05
Abstract: To determine the adhesion margin of a vehicle and for the resultant generation of warnings for the driver it is proposed that   - the adhesion potential and a driving state of the vehicle be detected, - the ratio of the driving state to a driving limit determined by the adhesion potential and adapted to the driving situation be determined, and simultaneously   - the current adhesion potential be evaluated and - a recommended highest speed be calculated from the adhesion potential and exceeding of this recommended highest speed be indicated to the driver.   The warnings are generated as a function of the situation. By means of distinctly higher warning thresholds for accelerations in the vehicle longitudinal direction, the driver is neither distracted by a warning in the case of emergency braking, nor irritated by superfluous warnings in the case of sharp acceleration.

IPC: B29C45/07
Filed: 1993-05-29
Abstract: An injection-moulding unit has a drive unit (A) for axially displacing the injection-moulding unit in the direction of the injection axis and an injecting unit (E), arranged symmetrically with respect to the injection axis (s-s), for axially driving a rotatable conveying screw arranged in the plasticising cylinder (17). The injecting unit is connected to an injecting bridge (25), which bears the conveying means. By virtue of the fact that the drive unit (A) likewise acts symmetrically with respect to the injection axis (s-s) and is integrated into the injection-moulding unit, a moment-free nozzle contact point and a compact injection-moulding unit are obtained in a constructionally simple way. <IMAGE>
Patent DE-4322456-A1 (DE)
Title: Adhesive tape
Inventor: ESSER HELMUT
IPC: C09J7/38
Filed: 1993-07-06
Abstract: Folding boxes are folded from cutouts consisting of cardboard. Box sides which abut with their free edges are joined to one another by applying an adhesive tape. Where possible, the adhesive tape is pressed onto the box sides prior to folding, if these sides are still lying flat on a level substrate. Then the adhesive tape can be pressed on easily and firmly. In the course of the subsequent folding or rotation of a box side about 90 DEG , the adhesive tape is stretched. In the course of this stretching, it may slip on the box sides and become detached from the latter. In order to avoid this deficiency, the invention proposes an adhesive tape which is elastic in the transverse direction. During the folding or rotation of a box side about 90 DEG , this tape is able to expand without slipping on the box sides.

Title: Displaceable safety steering column for passenger cars
Inventor: NABE MICHAEL DIPL ING
IPC: B62D1/19
Filed: 1993-07-05
Abstract: In the event of an accident, the risk of injury to the face and skull region is reduced, the driver can more easily be rescued and the steerability of the car remains intact. For the transmission of signals, use is made of triggering elements similar to those for the air bag. Said triggering elements open a gas cartridge (1), the pressure from which acts upon a pneumatic cylinder (2). This produces the force required in order to push the upper, movable steering column (3) into the lower, rigid steering column (4). This is made possible by a movable slide (5) which is fitted between the steering-column attachment on the vehicle body and the upper steering column. A section in the two-part steering spindle (6) ensures that the steering movements are transmitted at all times. The system is otherwise held in the off position by a catch. The safety steering column which is pushed together in the event of an accident and nevertheless remains steerable, is suitable for any type of passenger car. <IMAGE>
