Patent DE-3234641-A1 (DE)
Title: Digital colour television transmission system with composite encoding
Inventor: HENTSCHKE SIEGBERT DR ING
IPC: H04N11/04
Filed: 1982-09-18
Abstract: The number of quantisation steps of the coder/decoder for a digital transmission of a colour video signal (composite colour television signal) in composite form via a digital PCM transmission link is restricted to 8 bits per sample because of the predetermined bit rate. If the sampling frequency is not intended to be coupled to the colour subcarrier frequency, visible quantisation interference is produced in the transmitted colour television picture with the 8-bit encoding. For the purpose of a selective time compensation of the quantisation interference occurring, which is equivalent to an artificial 9-bit quantisation, according to the invention, a voltage (U1) which alternates line by line is generated in the encoder at the transmitter end and additively superimposed on the analog colour video signal. In the decoder at the receiving end, a corresponding voltage (U2) which alternates line by line is generated and subtracted from the decoded analog colour video signal. An identification signal (KS) also transmitted via the link in time-division multiplex at the beginning of each field allows the phase of the voltage (U2) generated in the decoder to be matched to the voltage (U1) generated in the encoder. <IMAGE>

Patent DE-3310547-A1 (DE)
Title: Circuit arrangement for generating supply voltages in a small dial-up PBX system
Inventor: FAHRENSCHON FRANZ DIPL ING
IPC: H04M19/00
Filed: 1983-03-23
Abstract: The supply voltages required for the different structural units (ST, M or RU) or structural elements of the dial-up system are derived from the AC sub-voltages which are generated through transformation from the AC mains voltage (Un). The generation of the AC sub-voltages is distributed over two conventional transformers (Tr1, Tr2). With one transformer (Tr2), those AC sub-voltages are generated which, following rectification in a controlled rectifier connected downstream, form the supply voltage (Uv3, Uv4) for those electronic structural units (ST, M) which respond in a particularly sensitive fashion to interference in this supply voltage. Due to the isolation of the supply voltages, required for the electronic units, from the other supply voltages which are derived from the AC sub-voltages generated by a further transformer (Tr1), no reciprocal interference can occur.

Patent DE-3412950-A1 (DE)
Inventor: OSYPKA PETER DR ING
IPC: A61B5/04
Filed: 1984-04-06
Abstract: A surgical electrode which can be used as a temporary lead for cardiac pacing or monitoring purposes has two elongated conductors whose distal ends are provided with spaced-apart poles and are implanted in a single operation by means of a surgical needle which is separably secured to the distal end of one of the conductors. The proximal ends of the conductors are connected to an elongated extension which passes through and outwardly from the thorax to be connected to a pacemaker or to an instrument which makes electrocardiograms. The conductors are insulated from each other and that pole which is nearer to the needle is defined by one or more bare strands which have a zig-zag, undulate, helical and/or other shape allowing the strands to reduce the width of the respective pole during penetration into the heart wall. The strands thereupon tend to increase the width of the respective pole to ensure reliable retention of the pole in contact with the surrounding tissue as well as to prevent migration of the pole in the heart wall. The needle is severed from the corresponding conductor when the two poles are properly implanted. The conductor which defines the radially expandible and contractible pole extends through the pole of the other conductor and is clampingly engaged by that portion of the other conductor which defines the respective pole so as to ensure that the pole of the other conductor shares the movement of the expandible pole during implantation into the heart wall.
