Date Aug. 25, 1988.An arrangement for selectively playing back and recording data in which a rotating disk-shaped recording medium is provided with data storage tracks. An optical system reads the stored data by guiding a light beam along the data storage tracks. The data read by the optical pickup system is decoded by a decoder which has an error output that emits a pulse for every bit error. The light beam strikes the disk-shaped recording medium at an angle and has a vector component which is tangential to the recording medium or disk, so that when the angle is 90 DEG , the vector component is zero. The bit errors are applied to a counter that provides the corresponding bit-error rate and provides a signal for controlling the adjustment for varying the vector component so as to maintain the bit-error rate below a predetermined threshold.

Abstract: A transmitter with controlled switches for use in a process for the generation of transmission current signals in an alternating current distribution network is connected to the supply network. When operated, this transmitter generates a series of current impulses. The moments in time of the generation of these current impulses and/or their duration are so chosen that the resulting transmission signal corresponds at least approximately to a desired theoretical signal. The transmitter contains at least two energy storages or energy storage devices and at least two switches for controlling the energy exchange between the two storages. These switches are so controlled that the exchange current flows through the mains, whereby the aforesaid current pulses are generated. It is thereby possible to use substantially only loss-free elements for the transmitter. The main field of application of the transmitter lies in ripple control technology, where it may be used as a transmitter in a central station (center) or as a transmitter for return signals to the center and for remote reading through the network of distributed meters with return signalling of the state of the meters to a center.

Abstract: A control system for a textile dying apparatus processes and distributes digitally encoded pattern information. A substrate is moved on a path along which the surface of the substrate comes into operative range of a plurality of arrays arranged along the path of the substrate. Each of the arrays has a plurality of individual dye applicators capable of selectively projecting a stream of dye onto a predetermined portion of the substrate corresponding to a pattern element in a pattern composed of a pattern element matrix with a plurality of pattern elements in each of a plurality of pattern rows. Each pattern element is associated with a visually distinct pattern area. The dye applicators project dye for a time period determined by the pattern information. The method first determines a set of initial values. From the initial values it generates a firing command matrix having, for each dye applicator in each array, a firing command sequence corresponding to the pattern element to which that dye applicator may apply dye in each pattern row. Finally, the method allocates, for simultaneous transmission to each dye applicator in each array, the firing command sequence in the firing command matrix corresponding to the pattern element in the pattern row to be applied to the predetermined portion of the substrate that is passing within operative range of the dye applicator at the time of transmission. <IMAGE>
