Abstract: Die Erfindung bezieht sich auf eine Schaltungsanordnung zum Aifbereiten eines abgetasteten Musters in einer Einrichtung zur maschinellen Zeichenerkennung. Zum Ausgleichen von Toleranzen innerhalb einer Fotodiodenmatrix einer Abtasteinheit (ABE) werden in einem einzigen Abtastvorgang verschiedene momentane, spaltenverschobene Lagen eines Abtastmusters als aktuelle Bildsignale (VID) miteinander verglichen. Dazu wird bei dem zunächst in einem ersten Bildspeicher (RAM1) zwischenzuspeicherndem Bildsignal die Anzahl der Schwarzelemente in einer Bildelement-Zähleinrichtung (VCTR) gezählt. Gibt das aktuelle Bildsignal (VID) ein "fettes" Zeichen wieder, werden die Weißelemente des aktuellen Bildsignals (VID) und eines in einem zweiten Bildspeicher (RAM2) zwischengespeicherten korrelierten Bildmusters (VIDk) in einem Schlaltwerk (SW) disjunktiv miteinander verknüpft. Bei "schwachen" Zeichen werden dabei die Schwarzelemente herangezogen. Sofern die Richtung der Relativgeschwindigkeit zwischen der Abtasteinheit (ABE) und einem Aufzeichnungsträger nicht festliegt, sind mehrere Lagen des korrelierten Bildsignals (VIDk) zu einem Vergleich in einer Vergleicherschaltung (COMP) heranzuziehen. Dieser Vergleich ergibt die Lage mit der besten Übereinstimmung. So läßt sich eine Mitte/Links- bzw. eine Mitte/Rechts-Verschiebung des aktuellen Bildsignals (VID) gegenüber dem korrelierten Bildsignal (VIDk) durch entsprechende Ansteuerung des Schaltwerkes (SW) ausgleichen. Diese Unabhängigkeit von der Abtastrichtung bietet einen Vorteil bei einem bevorzugten Einsatz der Schaltungsanordnung in Handlesegeräten.

Abstract: The invention contemplates a pipe-bending technique wherein an arcuate die which determines the course of bending the central axis of the pipe relies solely upon two tangentially engaging developing lines of contact which are spaced equally, at opposite offsets from the radial plane in which the pipe axis is bent. For the case of pipe bending to a circular arc, the opposed die faces are generally conical, and there is no pipe contact with the die in the range between the spaced developing lines of tangential contact.

Abstract: The disclosure relates to a cheek plate unloading pump for supplying fluid to a system. The pump has a discharge port concentric with its axis of rotation. The pump includes a rotor, a cam encircling said rotor and means for effecting relative rotation of the cam and rotor about an axis. A plurality of vanes are carried by the rotor and engage the cam to define pumping pockets which expand and contract on rotation of the rotor. A cheek plate extends radially of the axis and is disposed adjacent one axial side of the rotor and cam. The cheek plate is movable along the rotational axis to communicate expanding and contracting pumping pockets. There is a cavity on one side of the cheek plate, and a fluid passage conducts fluid pressure into the cavity which fluid pressure biases the cheek plate into a position blocking the flow of fluid from the contracting pumping pockets to the expanding pumping pockets. The pump also includes a servo valve for venting the pressure in the cavity to thereby control the flow of fluid between the contracting and expanding pumping pockets. A fluid passage in the cheek plate receives flow from the contracting pockets. The passage has a portion directing flow from the contracting pumping pockets radially inwardly of the cheek plate. A tubular member is fixedly attached to the cheek plate coaxially with the axis of relative rotation of the rotor, and the interior of the tubular member communicates with the portion of the fluid passage directing flow radially inwardly. A housing member defines a chamber in which the cam ring, rotor and cheek plate are located, and the housing has a discharge orifice coaxial with the tubular member. A seal is provided between the tubular member and the housing member enabling the tubular member to move with the cheek plate relative to the housing member while maintaining the seal.

Abstract: This monitor is provided, on the one hand, with a field deflection coil yoke which is controlled by a field deflection connecting unit having a field frequency of, for example, 50 Hz and, on the other hand, exhibits a line deflection coil yoke which is controlled by a line deflection connecting unit having a line frequency of, for example, 15,625 Hz. To avoid that, particularly in the case of terminal monitors of data processing systems, the values indicated, such as letters, numbers and points, always reappear at the same position and thus cause rapid wear of these positions on the screen, an individual additional control signal having a very low frequency is added both to the line frequency signal and to the field frequency signal in order to move a picture element slowly within a small area on the screen. As a result, the entire screen is utilised effectively.

Similarly, a stationary energy transmitter adjacent the chuck body transmits energy and a receiver on the chuck body receives the transmitted energy wholly without physical contact with the energy transmitter and powers the signal transmitter therewith. The transducers can be position or force transducers, for instance constituted by strain gauges or linear potentiometers. The signal and energy transmitters and receivers are formed by coaxial coils carried on a fixed support and on the chuck.

Filed: 1982-03-11
Abstract: The invention relates to a method and an apparatus for production of tubes and the resulting product. The invention makes the production of bent tubes possible by cold drawing of a hollow tube blank (10) in one operation for reduction of the outer diameter and the wall thickness. It is characterized in that a straight tube blank is drawn through a drawing tool comprising a drawing die (13) and a straight mandrel (12) which is short relative to the tube blank and applied centrally in the tube blank. Drawing means (15,16) attached to the tube end draw the tube along a pre-determined curved path, suitably in surface contact with a guiding device (17) with a pre-determined curved surface. For a pre-set angle between the central axis of the drawing die (13) and the central axis of the tube (10) at the exit of the drawing die, the tube gets a constant radius of curvature. Hereby production of tubes with a curvature adjusted to each purpose becomes possible.

Abstract: An interface circuit for providing power and signal voltages to a telephone line under the control of a microcomputer within the telephone exchange comprises four charge pumps, each comprising a pair of driver/amplifiers which charge a pair of capacitors through a first diode with two further diodes discharging the capacitors to charge a capacitor connected across the telephone line. The four charge pumps are arranged symmetrically to provide positive and negative potential at the tip terminal and positive or negative potential at the ring terminal. Modulation of the voltages to transmit a desired signal is obtained by modulating the power voltage supplied to the amplifier/drivers. The current drawn by telephone line is measured by sending the current drawn from the voltage source by the amplifier/drivers and this is used to extract the receiving signal from a telephone line and also to extract a measurement of peak current drawn from the tip and ring leads separately. The amplifier/drivers are diven by continuous square wave signal.
