Title: Procedure for reduction of the output bit rate of a digitised colour television signal
Inventor: HESSENMUELLER HORST DIPL ING
IPC: H04N19/00
Filed: 1985-08-14
Abstract: To reduce the output bit rate of a digitised colour television signal according to CCIR Recommendation 601, with a scan frequency of 13.5 MHz for the brightness signal and 6.5MHz for the colour difference signals, to an output bit rate of 68.736 Mbit/s, which is compatible with the PCM hierarchy by duplication, the scan frequency is first converted in the ratio 4:5 for the brightness signal and the colour difference signals (which are transmitted in line sequence), to 10.8 or 5.4MHz, with 576 or 288 picture elements per line. If the horizontal blanking interval is entirely used for picture information, the result with a 5-bit source coding of each scan value (e.g. with DPCM) is 4320 bits per line, and a net bit rate of 67.5 Mbit/s, which can be made up to the desired net bit rate of 68.736Mbit/s by forming a pulse frame consisting of 5728 bits and lasting 83.3 mu s. To simplify both multiplexing with other digital signals and cycle derivation at the receiving end, 22 extra bits, which can be used as required, can be added to the picture information in the horizontal blanking interval, giving 4342 bits per line with a net bit rate of 68Mbit/s, which is divisible by 2<8>, and which can be made up to the desired gross bit rate of 68.736Mbit/s by forming a pulse frame consisting of 4296 bits and lasting 62.5 mu s. <IMAGE>

Title: Device for the production of carrier bags with sinusoidal handle
Inventor: SCHNEIDER JAKOB
IPC: B31B70/00
Filed: 1986-03-04
Abstract: Device for the production of carrier bags with a sinusoidal handle comprising a layflat tubular plastic film web which is provided with printed markings and is subdivided into two half-webs by means of a sinusoidal cut executed in the longitudinal centre. The tubular plastic film web is fed continuously. The device includes a cycle compensating device, a sinusoidal cutting device, a spreading device for the half-webs, a phase adjustment device for the half-webs, a handle-hole punching device and a transverse severing device. The spreading device and phase adjustment device have two guide rolls for the half-webs and control motors. In the region of the sinusoidal cutting device there is arranged an optical/electrical scanning device which generates scanning pulses. By means of said scanning device, the printed positional markings associated with the individual carrier bags can be scanned. The scanning device is connected to a length control device which compares the scanning pulses assigned to it in temporal sequence with an associated coincidence point. The arrangement and the design are otherwise such that, in the absence of coincidence, the longitudinal control device actuates, via at least one control motor, at least one guide roll and by this means varies the longitudinal spacing of the half-webs between the sinusoidal cutting device and the transverse severing device such that the transverse severing cuts lie in the minimum of the sinusoidal cut. <IMAGE>

Title: Circuit arrangement for protection against reverse voltage on the mains connection of electrical apparatuses
Inventor: SCHNEIDER ANTON DIPL ING
IPC: H02H11/00
Filed: 1986-04-23
Abstract: A circuit arrangement is specified for protection against reverse voltage on the mains connection of an electrical apparatus (UPS). A sensor circuit drives interrupting switching means (T, t1, t2), which electrically cut the mains supply lead (L, N) off from the apparatus as a function of the voltage which is present on the mains supply lead. In the simplest case, the sensor circuit consists of an opto coupler (OK) whose light-emitting diode junction is connected on one side via capacitors (C1, C2) to the two live wires (L, N) and on the other side to the protective-earth conductor connection (SL) of the mains supply lead. A relay (T) is driven via the switching path of the opto coupler, in which relay (T) two normally-open contacts (t1, t2) are connected in the live wires of the mains supply lead. A sensor circuit which has higher reliability with respect to component failures is driven dynamically and controls the relay via a coupling capacitor. <IMAGE>

Title: Method for indicating solenoid-valve operation and a circuit arrangement for carrying out the method
Inventor: BIEHL KARL-ERNST DR RER NAT
IPC: G01R31/72
Filed: 1986-07-18
Abstract: A differentiating element (RC) which is connected to the magnet coil (L) of an electromagnetically operated valve detects voltage spikes which are induced during operation of the magnet armature. These voltage spikes are subjected to threshold-value assessment and pulse formation in comparators (K1, K2) by comparison with reference voltages, the pulses which are formed being supplied to the set input (S) or to the recess input (R) of a flipflop (FF). A signal then appears at the output (Q) of the flipflop (FF) only when the magnet armature of the valve has actually been moved, and the signal disappears only when the magnet armature is moved back again when the magnet coil is deenergised. <IMAGE>

Title: Circuit for the electrical supply of a pulsed gas laser
Inventor: OESTERLIN PETER DR
IPC: H01S3/0971
Filed: 1987-04-30
Abstract: An arrangement in which the sparks inside the laser chamber have an autonomous switch function optionally enables pre-ionisation of the operating gas of the laser and the generation of a compressed high-voltage pulse. For this purpose, a capacitive energy store (C2) is connected in a low-inductance manner to spark electrodes (1, 1') inside the laser chamber. The capacitive energy store (C2) is charged by a pulse-voltage source (2) and the current flowing during the spark discharge is used for pre-ionisation by means of the spark and for generating the compressed high-voltage pulse. The compressed high-voltage pulse can be applied to another circuit of the laser, as an operating, switching or control pulse. The sparks are triggered externally whenever the capacitive energy store (C2) has reached a maximum required voltage. For this purpose, a delay circuit (3) is assigned to the pulse-voltage source (2), which delay circuit (3) ignites triggering sparks on a spark gap (6) when the capacitive energy store (C2) has reached the maximum required voltage. The triggering spark gaps (6) are arranged adjacent to the spark electrodes (1, 1'). <IMAGE>

Title: Superheterodyne receiver with useful signal feedback in an FSH system
Inventor: MOTTAGHIAN-MILANI DARIUS-KARIM
IPC: H03D7/16
Filed: 1987-06-02
Abstract: The object of this invention is to design the radio-frequency stages of a superhet (direct mixer) so selectively that all unwanted frequencies are less strongly amplified or the required signal component is more strongly amplified. Immunity to interference signals, selectivity, sensitivity and far-off selectivity are thereby intended to be improved. For this purpose, the preliminary stage must therefore already operate selectively. However, this is difficult to achieve at radio frequencies using conventional selection means. The circuit is used in FSH in such a way that the signal is selected at a lower intermediate frequency, as in normal superheterodyne receivers, but is then mixed upwards again. This upward-mixed signal is then added in the preliminary stage to the input signal. The phase shift is selected in such a way that the upward-mixed signal and the input signal amplify one another. Therefore, the preliminary stage then amplifies the required frequency spectrum only. <IMAGE>
