Title: Device for controlling the speed of travel of a motor vehicle
Inventor: WESSEL WOLF ING GRAD
IPC: B60K31/04
Filed: 1985-03-09
Abstract: A device for controlling the speed of travel of a motor vehicle is proposed in which an actual speed value is compared with a reference speed value and a control variable is derived from this, which acts upon a position control circuit for a control element also operatable by the vehicle driver in order to influence the speed by way of the fuel metering. At the same time, means and signal paths are provided so that the derived control variable acts dynamically directly on the fuel metering. This results in a shorter response time for the vehicle speed control than would be possible without the dynamic intervention on the basis of the mass inertia of the control element.   <IMAGE>

Title: Arrangement for harmonic-free measurement of the speed of an elastic material web transported via a row of rollers
Inventor: AHRENS DIETER DIPL ING
IPC: G01P3/52
Filed: 1985-05-30
Abstract: The invention relates to an arrangement for harmonic-free measurement of the speed of an elastic material web, transported via a row of rollers, by means of tachometer generators mounted on the rollers. The invention consists in that an even number of tachometer generators are mounted on rollers which are not immediately adjacent, and between which an odd number of rollers are situated, and in that the measured value for the speed of the belt is formed from the arithmetic mean of the measurement signals of the tachometer generators. The tachometer generators are arranged as far as possible in the middle of a drive group. It is preferable to provide two tachometer generators. One roller is preferably situated between the rollers provided with tachometer generators. The selection of the rollers whose speeds are measured is performed in such a way that the natural vibrations of the system are contained in phase opposition in the measurement signals. <IMAGE>
Patent DE-3527647-A1 (DE)
Title: Resistance spot-welding tongs for industrial robots
Inventor: WEINTHALER ALFRED
IPC: B23K11/31
Filed: 1985-08-01
Abstract: The present invention is concerned with resistance spot-welding tongs for industrial robots. The starting movement commencing together with the working stroke in resistance spot-welding operations has hitherto changed the application force of the electrodes as a function of its direction in relation to the gravitational force. This uncontrolled application force has often led to a plastic deformation of the metal sheets to be welded together. This is prevented, according to the invention, in that the common centre of gravity of the mass to be accelerated during the starting movement remains at rest. The application forces can then be co-ordinated with great accuracy by means of springs or a cylinder/piston unit, so that plastic deformation of the spot-welded flanges no longer occurs.

Patent DE-3544421-A1 (DE)
Title: Method for measuring layer thickness in printing machines
Inventor: RUSCHER CHRISTIAN
IPC: G01B11/06
Filed: 1985-12-16
Abstract: The invention relates to a method for measuring layer thickness, in particular for the dynamic measurement of damping water layer thickness in printing presses. The aim of the invention consists in providing a method for measuring layer thickness which permits a higher sensitivity of measurement. It is the object of the invention to configure the method in such a way that changes in layer thickness influence the output signal of the measuring device more strongly. This object is achieved by using a beam splitter to split the beam emitted by the light source into at least two parts and directing them in different directions, detecting at least a part of the split beam directly by a first sensor and guiding at least a further part of the beam onto the prescribed measurement location and converting the light reflected from the measurement location by at least one second sensor into an electrical output signal, which output signal of the second sensor is used to control the light source, and using the signal of the first sensor as a measure of the layer thickness. <IMAGE>

Title: Method for AC voltage coupled transmission of digital signals on metal conductor pairs via connections in each case of differing lengths
Inventor: BERTELSMEIER MANFRED DR ING
IPC: H04L25/04
Filed: 1985-12-20
Abstract: For non-galvanic transmission of digital signals with bit rates up to and beyond 150 Mbit/s on coaxial pairs in each case via differing lengths, an initial recoding to CMI code is proposed, along with the use of invariable pulse formers at the transmitting and receiving ends which are optimised for a mean cable length and which form receive pulses in such a way that they can assume only a positive or a negative value at sampling times, which change their polarity gradually rather than in jumps, whose passages through the discriminator threshold are situated precisely mid-way between two sampling times and thus overall become immune to changes in the conductor length. The preferred application is a four-wire passive bus for connecting a plurality of terminal devices to the network termination unit of an ISDN broadband network. Applications for star-shaped broadband distribution networks are also possible. With a small coaxial pair, for example, 140 Mbit/s can be transmitted over lengths from 0 to 230 m without individual adapters (Fig. 1). <IMAGE>

Patent DE-3601451-A1 (DE)
Title: Self turning-off invertor
Inventor: SCHAEFER DIETER
IPC: H02M1/38
Filed: 1986-01-20
Abstract: The invention relates to a self turning-off invertor using a neutral or bridge circuit having valves which can be controlled by a control circuit, in reverse parallel with which there is connected in each case one diode. The invention is intended to create an invertor which turns itself off and in the case of which it is ensured at a relatively low cost and nevertheless with high reliability (safety) that the turning-on of a push-pull branch or of a bridge diagonal in each case takes place at the earliest when the hold-off interval (which is necessary for reaching the blocking capability of the opposing side) has with certainty elapsed. This is achieved according to the invention in that at least two valves, which are controlled in a push-pull manner, have allocated to them in each case one circuit arrangement which evaluates the voltage between the anode and cathode of the controllable valve, especially with respect to its polarity, and produces a corresponding binary signal, the input of which circuit arrangement is respectively connected to the cathode and the anode, and its output operates on the control circuit.
