Title: Reactive current compensation equipment for distribution systems - employs automatic sequence switching of capacitor banks
Inventor: APPEL GERHARD DIPL ING
IPC: H02J3/18
Filed: 1975-06-25
Abstract: A power factor correction system in medium or high voltage supply systems, is intended to reduce the switching time for changing capacitor banks by introducing sequence controlled operation. Sequence control stages (A-E) operate the main switch (17) to disconnect the outgoing bank and also close the earthing and discharge switch (21). The sequence proceeds by closing the required selector switches (14, 15), tripping the discharge switch and reclosing the main switch. The disconnected time is typically 3 seconds, and no special time delay is required if the discharge resistance (22) has a low value. Such a sequence system may by coupled to a closed loop controlled for automatic switching to the correct capacitance value for desired degree of compensation.

Title: Alkylation of unsaturated hydrocarbons - with alkyl halides or olefins, using metal halide catalysts which lose activity
Inventor: DIALER KURT PROF DR
IPC: C07C2/68
Filed: 1976-06-23
Abstract: Alkylation of unsatd. hydrocarbons with alkyl halides and/or olefins, using a catalyst system of Bronsted acid and a metal halide which is converted to an inactive form during the process. Progress of the alkylation and deactivaton processes are controled by varying the concn. and material flow to achieve optimum yield of the required alkylation prod. Formation of unwanted highly-alkylated prods. can be avoided without use of a large excess of the original hydrocarbon, e.g. benzene, or recycling of highly-alkylated prods. which causes unwanted side-reactions, esp. when higher olefines or alkyl halides are used. Reduced amts. of catalyst can be used and distn. of the prod. is simplified. FeCl3 is a selective and mild catalystm which does not promote isomerisation reactions, and is pptd. as FeCl2 which can be filtered off.
