Abstract: With a device for pressing at least one magnetic read/write head (16) against a recording medium (14) in motion relative to it with a swivel-mounted pressure lever (52) carrying the read/write head (16) that runs in the recording medium's (14) direction of motion and is pressed to the recording medium (14) by means of spring force and with stationary guide elements (76, 78) that limit read/write head (16) movement at right angles to the recording medium's (14) direction of motion. The read/write head (16) is equipped with pivot pins (90, 92) that, in the pressed operating position of read/write head (16), define a swivel axis lying approximately parallel to recording medium (14) as well as its direction of motion and that are held in the position at pressure lever (52) as well as by means of guide elements (76, 78) that are displaceably directed in the direction of pressure of the read/write head.

Abstract: A programmable logic array chip is provided with an auxiliary grid pattern of conductive paths. Connecting elements can be selectively activated to connect certain ones of the auxiliary paths to the normal grid pattern paths which are connected to functional elements. In such manner, it is possible to provide a logic array chip that has increased flexibility in terms of user programmable functions.

Abstract: In a device for friction-driven conveyance of a card-shaped recording medium (14), such as an I.D. card, relative to an evaluation device (16) which is situated on an extended linear transport path (36) between an inlet (38) and an outlet or reversal point (40), the linear transport path (36) is bordered on the one side by a section of a closed-loop conveyor (26) and on the other side by a pressure strip (28) which runs approximately parallel to the path (36) and is stressed toward the conveyor (26) with the aid of a pressure device (52). Rollers as active transport elements are thereby eliminated, insuring error-free transport of even deformed recording media.

Abstract: In an output circuit for a signal transmission system to generate a bipolar output signal, a power output stage (62) is driven by a data signal and a transmitter release signal via an isolation stage (18) and a logic network (64). The power output stage comprises two complementary transistors whose bases are each separately driven from an output (50, 56) of the logic network (64) so that only one of the two transistors (54, 60) is switched to conducting in the presence of a transmitter release signal corresponding to the polarity of the output signal to be produced and so that both transistors (54, 60) are closed, independent of the data signal, in the absence of a transmitter release signal.

The viewing screen housing (6) has the shape of a circular cylinder segment, where the viewing screen plane essentially coincides with the intersecting plane (10) of the circular cylinder segment and the pivot axis (4) coincides with the cylinder axis. In a preferred embodiment, the viewing screen housing (6) is fastened swivelably onto a receiving housing (8) containing at least part of the components. The receiving housing (8) is provided with a concave recess (19) turned toward the viewing screen housing (6), which recess fits closely against the curved rear wall of the viewing screen housing. The supporting of the swivelable viewing screen housing is preferably done by supporting means which act on either the inside of the end faces or on the curved back side of the viewing screen housing (6).

Abstract: In checking a program in data processing units, the working memory, before the completion of the program, has written into it information to which respectively a false parity signal is assigned. In this way program mistakes in the program to be checked, which can be revealed in a read access to a non-normalized memory cell, are recognized instantly.

Abstract: The invention relates to a device for selectively notching or severing a paper strip (18), e.g. a cashier's bill, in a printer. The cutter (2) is pushed to and fro by means of a sliding block (38) arranged on it by way of a pivot, which block engages in a slide track (28). The sliding block (38) can assume two different angular positions in the slide track (28), in which the pivot (36) connecting the slide block (38) with the cutter (2) is located either radially inside or outside of the center line of the slide track (28), so that the cutter (2) reaches different end positions, in one of which the paper strip (18) is notched and in the other of which it is severed. The setting of the different angular positions of the sliding block (38) takes placed automatically through a choice of the rotation direction of the crank disk (26) showing the slide track (28).

Abstract: An apparatus for reading by blind persons comprising a data medium in the form of a thick elastic belt and having formed therein a dense uniformly spaced two-dimensional array of data elements of thin membrane-like construction integral with the belt and capable of assuming stable convex and concave conditions wherein they either project upwardly from the belt to be sensible by a person's finger or down into the belt where they may not be felt. Because of the thickness of the belt, the data elements are also capable of assuming intermediate unstable conditions wherein they do not experience a transition to the opposite state simply because they are compressed flush with a surface of the belt. Means are provided for setting and resetting the data areas.

Abstract: In the recording of information signals the signal elements of which are to have a prescribed length, a read/write head (WRT) is used in which the write gap (W1) is at a distance from the read gap (R) corresponding to the prescribed length. When a signal edge occurs at the read gap (R), an evaluation circuit (FIG. 4) controls the write gap (W1) in such a way that the latter records the next signal edge. For recording by the NRZ process, a further write gap (W2) can be provided between the write gap (W1) and the read gap R, which is controlled like the first and makes possible the recording of binary signals.

Abstract: A signal processing circuit for a signal varying in its properties, e.g., in its degress of distortion, in which the input signal is fed in parallel to two similar processing circuits e.g., equalizers, the characteristic of which can be varied by a control signal, wherein the control signal from the one processing circuit is periodically varied and the output signal is fed to a detector circuit which in optimum signal processing emits a trigger pulse to a holding circuit 52 which stores the corresponding control signal level, which is fed to the second processing circuit.A variable delay unit for the data is controlled by a continuously varying up-down counter, the contents of which continuously vary at the rate of a high frequency clock pulse. The direction of count and the time of the count is controlled by comparing the relative time-positions or phases of a timing pulse received with the data and a timing pulse generated at the receiver.

Abstract: Process for producing a multipolar multipoint connector (terminal strip) with a plurality of contact prongs arranged one beside another on a plastic carrier or the like. For this all of the contact prongs still joined together by webs are assembled on the carrier in one operating step and only then are cut apart (or separated) from one another. An improved carrier as well as a better assembling (or mounting) ensure a form-locking joining of the contact prongs with the carrier. Besides this, a process for providing the new multipoint connector is supplied.
