Patent DE-3832491-A1 (DE)
Inventor: SCHURICHT MICHAEL
IPC: H04Q11/04
Filed: 1988-09-22
Abstract: Interface-specific procedures in the form of alternate sending and receiving of data are carried out between the network termination which constitutes the limit of the user domain and the user terminals. The order of the data sequences and the duration of transmission of each data sequence are predetermined, which impedes measurements in the user domain. This difficulty is overcome by using a test pattern generator which can organize all data sequences required for the operations in an order and for a duration which facilitate measurement. The generator can also produce freely definable data sequences for the measurements. In addition, the generator is capable of producing control and/or identification data in synchronization with the data sequences. Application: measurements in the user domain of an ISDN system.

Filed: 1988-10-22
Abstract: The invention relates to a brightness control circuit for incandescent lamps and switched-mode power supplies without the interference suppression elements requisite in the case of triac dimmers. To solve this problem, the invention proposes that a self-locking field effect transistor in the diagonal of a bridge rectifier or two series-connected or parallel-connected MOS-FETs are controlled by means of a control circuit in such a manner that during zero crossing of the alternating voltage one field effect transistor is always conducting and, corresponding to an adjustable time in the control circuit, remains in the conductive state for a desired section of the mains half-cycle and switches off after that with an appropriately set edge before the next zero crossing has been reached.
Patent DE-3836843-A1 (DE)
Inventor: GOEBEL PETER
IPC: F24H1/40
Filed: 1988-10-26
Abstract: In a burner-heated apparatus with a heat exchanger (3) which is arranged in the waste gas guide (2) of the burner (1), which leads to a chimney (5) or similar waste gas take-off, and is flowed through by the waste gases of this burner (1), a portion, which can be selected as required, of the waste gases from the combustion chamber (8) is conducted directly into the chimney (5) or similar waste gas installation, in order that the temperature there is not allowed to fall below the dew point and as a result the formation of condensate is prevented. The size of this waste gas portion to be conducted off directly into the chimney (5) or similar can be defined from case to case taking the respective local conditions into consideration. The supply of uncooled waste gases can take place via a bypass guide (9) or the heat absorption capacity of the heat exchanger (3) can be reduced selectively. <IMAGE>

Title: Method of detoxifying process exhaust gases in plasma etching
Inventor: FABIAN WERNER DIPL CHEM
IPC: B01D53/70
Filed: 1988-11-17
Abstract: In plasma etching processes, predominantly employed in semiconductor technology, depending on the process conditions, toxic gases of the compound classes carbonyl halides (phosgene) or pseudo-halides (plasic acid and dicyan (cyanogen)) can form. Furthermore, in addition to the existence of acidic gases such as hydrogen chloride and hydrogen fluoride, the occurrence of pnictide halides and chalcogenide halides and arsenic(III) chloride must be expected. Since hydrogen is also used as carrier gas in plasma etching in semiconductor technology, under unfavourable conditions, highly toxic covalent hydrides such as phosphine and arsine may form. The purification method provided describes a single-stage gas-scrubbing process which removes all neutralisable and oxidisable toxic gas components from the exhaust gas by alkaline oxidation. Silicon halides which are difficult to hydrolyse are simultaneously converted by complex formation using alkali metal halides or alkaline earth metal halides into hexahalosilicates of low volatility. Remaining halogenated hydrocarbons are removed by adsorption on specially activated carbon.
