Patent DE-4405883-C1 (DE)
Inventor: ZIMMERMANN GERHARD PROF DR
IPC: C10G9/16
Filed: 1994-02-21
Granted: 1995-08-10
Abstract: Tubular reactors or heat exchangers in processing plants for hydrocarbons and other organic compounds at high temperatures in the gaseous phase are to be protected against coke formation. The problem in such plants is that the usual steam/air cleaning process for removing coke deposits causes an increase in the catalytic activity of the material surfaces, which shortens the service life of the plant. The object of the invention is to substantially reduce coking and to maintain the long term passivity of steels for long working periods. The disclosed process for producing thermally cracked products from hydrocarbons and for reducing at the same time coke formation on heat exchanger surfaces is characterised in that 20 to 1000 ppm of an additive composition containing organically bound silicon and sulphur are added to the feed to be cracked, and the mixture is brought into contact with the heat exchange surfaces at temperatures in a range from 400 to 1000  DEG C.

Title: Sampling rate conversion for use with video signal decoding
Inventor: DEMMER WALTER
IPC: H04N7/01
Filed: 1994-07-01
Granted: 1995-08-17
Abstract: A sampling rate converter is used in digital video signal decoders for use in TV reception to provide a precise and distortion free reproduction. The input digital signal has a specific clock rate and this is converted into a signal with a second 'virtual' rate.  The processing involves the stable interpolation between two successive sample values and includes an amplitude correction. The process is repeated until the frequency value achieves the required resolution. The process uses a Walsh-Hadamard transformation.

Title: Phase synchronisation system for radio data signal receiver
Inventor: ROITHER GERHARD
IPC: H04B1/16
Filed: 1994-12-08
Granted: 1996-04-18
Abstract: The phase synchronisation system allows a bit rate clock signal (5) generated in the radio data signal receiver to be synchronised with the demodulated radio data signal (1) having the same bit rate. A control signal (RESET) is supplied when the radio data signal receiver is switched in, or switched to a different transmitter frequency, for initiating a shift in the phase angle of the bit rate clock signal at the next leading or trailing flank of the received radio data signal. Pref. the bit rate clock signal is supplied via an oscillator coupled to a frequency divider (FT) with a reset input for setting it to a given count value in response to the detected pulse flank of the radio data signal.

Title: Equipment is for absorption of collision energy between a train and living being and incorporates activation devices, support component for being during and after collision and shock absorption component
Inventor: HORST JAAP
IPC: B61F19/06
Filed: 2004-12-29
Granted: 2006-06-30
Abstract: The equipment is for absorption of collision energy between a train and a living being and incorporates activation device, a support component for a being during and after a collision and a shock absorption component. The support and shock absorption components are fitted in or on the front side of the train for activation by the outward folding of at least a part of them from the front side of the train shortly before or during a collision. On the front side of a train (2) a catchment device (1) is arranged, which in a passive state is inwardly folded. After the detection of a living being on the rails by a sensor (10) or by the action of the driver, the equipment is activated. This causes four tubes (11,12,13,14) to be extended outwards. On the front of the tubes, a net (5) is arranged. The under side (7) of the net is concave for prevention of the risk that the net touches an object on the ground. The net is supportable by the tubes whilst the being is collected, whereby the net can stretch adequately into the space between the tubes in the direction of the train.

Title: Stand-by stage of protection against short-circuits
Inventor: LEVITSKIJ VALERIJ M
IPC: H02H3/08
Filed: 1987-09-14
Granted: 1994-07-15
Abstract: FIELD: electrical engineering. SUBSTANCE: stand-by stage of protection against short-circuits has resistance relay, first element of operation delay. Resistance relay is provided with unit of change of setting of operation by voltage circuits. Novelty of stage lies in its fitting with supplementary element of enhanced automatic sensitivity, first and second logic AND gates, second element of operation delay, first logic OR gate. In case of short-circuit in zone determined by setting of relay 1 signal "1" emerges across its output and signal "0" across output of AND gate 10 which leads to triggering of element 8, to emergence of signal "0" at output of element 8 after its operation and of working signal "0" at output of OR gate 12. Triggering of element 13 is blocked by appearance of signal "0" at output of device 18 after operation of relay 1 and with emergence of working signal across output of filter 19 with fault to ground in protected network. In case of short- circuit in protected zone signals "0" will emerge across outputs of AND gate 15, elements 16, 14 when signal "1" emerges across output of unit 17 with its triggering if relay 1 operates due to short-circuit outside operation zone. It results in blocking of operation of protection stage with time delay of element 8 by second input of AND gate 10, in change of setting of relay 1 to bigger operational resistance, in improvement of its tunning-out from load currents and of current selectivity of its operation due to operation of units 2 and/or 3, 4, 5, 6, 7. In case of short-circuit in zone determined by new operational setting of relay 1 AND gate III operates, element 9 is triggered and after time delay of it signal emerges across output of OR gate 12. For provision of selective action of stand-by stage of protection after its selectivity was improved by operational resistance time of delay of element 9 is chosen from condition of its agreement with time of delay of stand-by stages pf preceding sections of protected network. Protection circuit returns to initial state after return of unit 17 and emergence of signal "0" at input 21 of element 14. Action of element 14 on input of one of elements of change of its characteristic can be sufficient depending on selected settings of relay 1 under condition of improved sensitivity and loading of protected connection for tuning away from these currents. EFFECT: increased speed of action, expanded protection zone. 9 cl, 9 dwg
