IPC: B05B14/44
Filed: 1992-08-01

Title: Motor vehicle control installation allowing for tyre size tolerances - applies two=stage filtering with feedback of computed free-running wheel speeds and allowance for vehicle geometry and track width
Inventor: KOST FRIEDRICH DIPL ING
IPC: B60T8/171
Filed: 1992-09-10
Abstract: Measurements or estimates of yaw rate (psi'), transverse velocity (Vy) and steering angle (delta) are used (1) in conjunction with vehicle-specific constants (Rv, beta) and free-running wheel speeds (vfr2-vfr4) in calculation of reference tolerances (phi 2 - phi 4). First-order filters (2,3) are applied to obtain absolute tolerances (r2-r4) for a final calculation (4) of the speeds to be compared with a reference wheel speed (vr01) in a controller (5). An AND gate (6) activates these computations only when eight specified conditions related to vehicle operation are fulfilled. USE/ADVANTAGE - In antilock braking and wheel-slip control systems, much more precise correction of wheel speed signal is possible even at low traction and steering torques.

Title: Anti-theft/break-in device for cars
IPC: B60R25/01
Filed: 1993-01-08
Abstract: A device to deter car break-ins has the doors, soft top and trunk lid unopenable from the inside once the regular locking using the correct key has been done, usually involving code cards or hand-held transmitters. The deterrent for unauthorised starting or driving away has voltage available at the ignition switch only if the door locks have been activated with the correct keys.

Patent DE-4305864-A1 (DE)
Title: Output buffer digital driver - has overshoot limiting and changes impedance with output voltage
Inventor: YASUDA KENICHI
IPC: H03K17/16
Filed: 1993-02-25
Abstract: The output buffer circuitry consists of logic circuit (4 - 8) outputting complementary signals to PMOS and NMOS driver transistors (1,2) respectively when an output enable signal (OE) is true. In parallel with the driver transistors are circuit blocks (A,B) contg. a current source (9,10) and source follower transistor (1a,2a). The chip connection and lead inductance is represented by an inductor (L). The circuit reduces over- and undershoot by raising the output impedance as the output voltage approaches the supply rail voltages (Vcc,Vss). This is a result of the current sources cutting off as the voltage across it falls. The drive current is then supplied by only. USE/ADVANTAGE - For HF digital integrated circuits. Minimises over- and under-shoot without lengthening time for valid output signal. Signal rise and fall times are unaffected.

Title: Method for the optimum control of a carriage for a serial printer
Inventor: KIM HONG JANG
IPC: B41J19/20
Filed: 1993-05-05
Abstract: A method for the optimum control of the carriage of a serial printer which is capable of printing line by line is disclosed. When controlling the carriage motor, prior to the head being driven, the carriage motor is controlled, based on the carriage drive base unit, i.e. 1:360 inches, thus making it possible for the head firing position to be recognised precisely.

Patent DE-4329072-A1 (DE)
Title: Motor=driven mechanism to open and close injection mould - moves mould plate between two fixed plates by toothed belt drive and nuts with balls fitting grooves along rods fixed to moving plate
Inventor: AOKI HIDEMI
IPC: B29C45/17
Filed: 1993-08-29
Abstract: A motor=driven system for closing and holding an injection mould has one fixed mould plate on a platform and another fixed plate opposite it; the moving mould plate is mounted between these two; a number of tie rods cross the space between the two fixed plates horizontally and pass through the moving plate; each tie rod has a length in the form of a revolving thread which is located in the moving mould plate; each such threaded length engages a nut which is rigidly attached to a toothed belt pulley so that, when the motor is energised, the moving plate is moved to or from the fixed plate. The motor is mounted on one of the two fixed plates; a ball box i.e. a bush with balls on its id is mounted so as to revolve in a fixed casing which itself is let in to the moving mould plate; a shaft passes through the ball box and has longitudinal ball grooves to hold the balls of the ball box and so allow the moving plate to be moved along the shaft. The complete assembly of nuts, ball box, shaft and motor causes the nuts to turn and the moving plate to proceed to/from the fixed plate when the motor is operated. An example shown has the two fixed plates (1,2) on the platform (3), with the two horizontal tie rods (4) which pass through the moving plate (5). This latter plate (5) moves on bottom guides (6) on the platform (3). Each tie rod (4) has part of its length in the form of a spindle (7) with balls fitting in. ADVANTAGE - The system moves the one plate over its platform with high degree of accuracy and parallel to the fixed plate. The tie rods across the assembly do not have to revolve. The system requires only a relatively low power motor with low torque and low power consumption.

Patent DE-4406661-A1 (DE)
Title: Screw set for fitting underneath or onto shower trays or bathtubs
Inventor: BERG JUERGEN
IPC: A47K3/04
Filed: 1994-03-01
Abstract: Until now, shower trays and bathtubs have been underpinned, after installation, with hollow blocks; occasionally, the trays/tubs are also surrounded beyond the tray/tub rim, thereby additionally providing a place on which to deposit something or to sit. The underpinning or surrounding serves primarily for the fixture of tiles, resulting in a sealing unit which encloses the shower tray or bathtub and enhances the overall appearance. This activity, which is generally carried out by the tiler, represents an additional cost factor for the latter in the form of time and labour. By means of the invention, a further-processing (adhesive bonding, drilling) is possible immediately after the mounting of the screw set. In contrast to the previous method, waste and also waiting times are avoided; environmental pollution is prevented by virtue of the fact that the product consists of 100% recyclable material. The invention is usable in any installation of shower trays or bathtubs, whether large-scale project or merely a single property, by the expert or layman, thereby enabling more effective working.

Patent DE-4410960-A1 (DE)
Title: Method for suppressing the effect of roll eccentricities
Inventor: JUNGKUNZ CLEMENS DIPL ING
IPC: B21B37/66
Filed: 1994-03-29
Abstract: The method concerns suppression of the effect of roll eccentricities (delta R) on position or thickness control of a roll stand. The roll eccentricities are reproduced by the output signal (delta R') of an oscillator (22) with feedback, with the frequency of this signal adjusted in accordance with the roll speed. At the same time, the amplitude and phase of this signal, which is fed to the control system of the roll stand, depends on its difference (e) from the sum (u) constituting a product of the measured rolling force (Fw) and the reciprocal of roll and rolled material stiffness. The difference (e) is established with utilisation of the target value (s asterisk) of the roll setting position. The measured rolling force is supplied to the oscillator (22) via a proportional-differential element. Further oscillators with feedback are foreseen for suppression of harmonics of the roll eccentricities. Such oscillators are connected in series, or their output signals are additively combined with one another.
