Abstract: 1. A method of compensating errors caused by temperature changes in A.C. measuring devices comprising measuring means with impedances, in particular for inductive distance measuring equipment with measuring coils forming part of a resonant circuit, characterized in that a constant current having a frequency far below the distance-measuring frequency is supplied to said measuring means additionally to said distance-measuring frequency, whereby a compensated signal (US ) being proportional to said distance is derived from an A.C. measuring signal (Ud ) corrected by correcting signal (Ukorr ) which in turn is achieved by a voltage (UT ) from the output of said measuring means.

Title: Foam extrusion apparatus and method
Inventor: CISAR JAMES R
IPC: B29C48/90
Filed: 1983-09-12
Granted: 1987-10-08
Abstract: A foam extrusion apparatus and method in which extrudate is extruded into a sealed chamber (20) which may be subjected to pressure variation such as a vacuum with the controlled shaping of the plastic being obtained by power driven rolls (28) within the chamber downstream of the die (26). Because of the harsh environmental conditions within the chamber it is desirable that the shaping or forming rolls be driven by an externally powered source which will therefore be not subject to the pressure, vacuum, or other deliterious conditions found within the chamber. Moreover, because of the external position of the drive with regard to the chamber, the entire system need not then be shut down in order to open the chamber and make the required adjustments or repairs. The chamber is preferably the upper end of a barometric leg into which the extrudate passes. The upper end of the chamber is closed by one or more bulkheads (23) which are movable toward and away from the upper end of the chamber. The present invention utilizes DC drive motors (36-40) on the exterior of the bulkheads and of course the chamber to drive the shaping rolls which are downstream of the die. With this arrangement, both torque and speed may be closely controlled and of course the chamber does not require to be opened to make adjustments, replacements or repairs to the power system.

Title: Stored program control with word and bit processor
Inventor: NINNEMANN PETER DIPL ING
IPC: G06F15/16
Filed: 1984-01-16
Granted: 1988-07-07
Abstract: A memory-programmable controller of the multiprocessor type, has both a fast bit processor for processing bit oriented operations and a slower word processor for processing word oriented operations. The bit and word operations are stored in a user program memory by the user. These operations are the program which controls the peripheral process controlled by the controller. The bit processor reads the user program memory and sequentially stops when a word command is recognized. The bit processor furnishes information which the word processor uses as the entry address for a program routine associated with the word command in an operating system memory. This provides freedom in the choice of the word processor and in the design of the bit processor to a high degree.

Abstract: A driving and positioning system consisting of a rotor equipped with permanent magnets and of a stator with at least two windings. The windings are connected to an electronic voltage-supply circuit controlled by rotor-position sensors for commutating the current. To improve its adjustment potential by converting the system into one that can be magnetically meshed or latched, the stator is non-ferrous, the disk-shaped stator windings, which are positioned in parallel planes, are overlapped in such a way that the magnetic field generated by the windings and surrounded by the coils is essentially parallel to the magnetic field generated by the permanent magnets, and the rotor-position sensors are each integrated into both windings. A practical electronic voltage-supply circuit for controlling the system is also described. It has two sets of multiplication stages and a set of addition stages in a prescribed layout.

Abstract: A load monitoring system for a road vehicle has a strain link mounted at a location on the vehicle which has been carefully chosen to provide an accurate and reliable representation of the applied load. Ideally this location is centrally of and on top of a single-wheeled axle of the vehicle. A microprocessor-controlled computing apparatus processes the sensor output to provide computer outputs representing such load parameters as axle weights gross vehicle weight, and payload, and a combined display and manual control console has a digital which can be made to display all of the load parameters in a predetermined sequence. The system has an inclinometer for measuring vehicle inclination and compensates for such inclination at the time of measurement. Also, the system can compensate for fuel level so as always to give readings for the load parameters as if the tank or tanks were full. These features combine in the disclosed embodiments to provide accuracy required to ensure compliance with strict legal requirements without having to substantially underload the vehicle.

Abstract: A detector for an alarm system receives a disturbance signal and transmits an alarm signal to a remote station. A group of such detectors can be connected in circuitto operate a common alarm. The detector has means (6,26,33) for suppressing a first disturbance signal so that only a second and subsequent ones trigger the alarm. There are also means (8, 30) whereby a disturbance signal only of a given length can pass to trigger the alarm. With another facility (38, 43) the detector registers whether it is the first or a subsequent one in a group to be disturbed. The detector is largely embodied on an integrated circuit chip and all these facilities are selectable by making or omitting simple pin connections.
