Filed: 1986-07-09
Granted: 1987-10-15
Abstract: For the contribution- or time-controlled recording of television programme contributions, static actual contribution identification information is transmitted as data lines within the television signal which contains the associated television programme contribution. The actual contribution identification information, after having been separated from the television signal and the remaining teletext data, is compared with stored nominal contribution identification information, the switching-on and -off of the recording operation being derived from the result of the comparison. When the actual contribution identification information is missing or cannot be evaluated, the recording operation is switched on and off under time control as determined by the time information contained in the nominal contribution identification information. According to the invention, at least one data line with actual contribution identification information is transmitted in each of n successive frames after each change in the contribution identification information. During the remaining transmission time up to the in each case next change in the contribution identification information, in contrast, at least one data line with actual contribution identification information is transmitted in each mth frame. If x successively received actual contribution identification information items are identical, a contribution-controlled recording is effected.

Title: Pyrolysis plant for the thermal decomposition of hydrocarbon-containing starting material
Inventor: LEHMANN KLAUS DR-ING
IPC: C10B47/24
Filed: 1987-12-17
Granted: 1989-03-09
Abstract: In pyrolysis plants, the solids produced during dedusting of the pyrolysis gas have to be discharged without coming into contact with the ambient air. To this end, a lock system is provided which conveys the solids, with the aid of a collection chamber (36), into a tote box (56). The tote box (56) is connected, via a readily detachable first line coupling (52), to the bottom end of the collection chamber (36), whereas an equalisation duct (72) connects the tote box (56) to the upper end section of the collection chamber (36). At the same time, via a readily detachable third line coupling (82), a storage vessel (78) for an inert gas is connected to the interior (54) of the tote box. Thus it is possible, in a simple manner, to discharge the solids, without them coming into contact with the atmosphere, from the pyrolysis plant, so that explosive pyrolysis-gas/air mixtures are avoided and operational safety is considerably increased. <IMAGE>

Title: High-power switching path for protective switching devices
IPC: H01H73/18
Filed: 1988-02-09
Granted: 1989-08-10
Abstract: This invention achieves rapid arc extinguishing by interrupting the contacts as quickly as possible, and a high degree of current limiting is achieved irrespective of the current waveform and magnitude. In this case, the short-circuit current itself is used in a progressive manner, as a result of the particular manner in which it is fed to the contact point, to open the switching path virtually without any delay. At the same time, this interruption is carried out completely independently of the unlatching of the latching mechanism by the magnetic release. The arrangement of the rotary bearing point of the moving contact results in said contact not being touched by the base of the arc, so that welding is reliably prevented, but the electrical load also being so low that it is possible to dispense with an additional current-carrying braid, and in the arc being commutated without any delay. The course of the arc is in this case not impeded or braked. An additional blowing effect is achieved which is particularly useful for interrupting weak-current DC arcs.
