Patent DE-4136532-A1 (DE)
Title: Determining selectivity limit of series-connected power switches - determining operate margin of magnetic trigger of main switch by calculation of three parameters
Inventor: GROSSE-WILDE HUBERT DIPL PHYS
IPC: H02H3/00
Filed: 1991-11-06
Abstract: The method involves determining the trigger characteristic of a main power switch (2) by measuring the current pulses of differing length and amplitude at the operate margin of its magnetic trigger. The equilibrium current and saturation current are determined for which the trigger integral of the measured current pulses has the smallest quadratic deviation from the arithmetic mean, and the arithmetic mean is defined as the trigger discriminant of the trigger. The selectivity limit is calculated by determining the trigger integral for each short circuit current with the corresponding forward current of a branch switch (4), and comparing with the trigger discriminant. USE - For series circuit of power switches with subordinate branch switches.
Patent DE-4137865-A1 (DE)
Inventor: LORENZ DIETER
IPC: G01R15/14
Filed: 1991-11-11
Abstract: A high-voltage measurement device for an electrical high-voltage switchboard plant has a measurement electrode (4) built into an encapsulating housing and an electrical conductor (6) conductively linked thereto and insulatingly led through the wall of the encapsulating housing (1) for transmitting a measurement signal. In order to protect service staff from the high-voltage at the conductor, the conductor (6) is earthed outside the encapsulating housing (19) by metallic springs (10, 11) which may be if necessary lifted off the conductor (6) by actuating means (15, 16, 17, 18). For example, this may happen before each intended measurement by setting a switchboard housing (19) on a measurement housing (7) that encloses the conductor (6). When the switchboard housing (19) is removed, the conductor (6) is automatically earthed once again by the metallic springs (10, 11). This high-voltage measurement device may be used with all kinds of gas-insulated high-voltage switchboard plants.

Filed: 1992-09-08
Abstract: The object of the invention, by means of an activating electronic unit for the variable displacement pump, is to effect automatically hydraulically regulated adaptation of the delivery flow of the variable displacement pump as a function of the volumetric flow of the different hydraulic consumers at constantly controlled pump pressure. The method according to the invention, after input of the various pressure values into the input unit (16) for the individual hydraulic consumers (12, 13, 15) connected in parallel, provides for the activating electronic unit (4.1) for the variable displacement pump (1) to determine the maximum operating pressure from the pressure values.

Title: Modified metal oxide layers as supports for active compounds and reagents
Inventor: BOETTCHER HORST PROF DR RER NA
IPC: A61K8/02
Filed: 1993-03-15
Abstract: The present invention describes the modification of metal oxide layers as supports for active compounds and reagents by the addition of penetrants during the layer formation process (from the gas phase or from solution). The function of the penetrants is either to increase the porosity of the metal oxide layers by extractive or thermal removal and thus improve the possibilities of reaction with incorporated or adsorbed active compounds or as an insoluble additive to change the solid structure of the metal oxides in such a way that the support behaviour towards adsorbed active compounds and reagents is improved.

Title: Process and apparatus for work-zone and room-air conditioning preferably for textile machines
Inventor: RUPP HEINRICH
IPC: F24F13/26
Filed: 1993-03-15
Abstract: The invention relates to apparatuses for the controlled air-conditioning of work zones in production machines which process hygroscopically sensitive materials and which allow optimum running properties in a narrow temperature and atmospheric-moisture range only. The apparatuses can produce in an individually adjustable manner different air states at specific distances from the air outlet. In contrast to known processes for mixed air-conditioning which require two separate air-conditioning systems for room air and process air, only one incoming-air system for a multiplicity of machines is required in the apparatuses according to the invention. This is achieved by means of appropriately dimensioned blow-out surfaces and blow-out slits which, by means of controlled flaps, allow a variable setting, that is to say, on each individual machine, different temperatures and relative atmospheric moistures can be set within the scope of the physical possibilities. A further advantage is the considerable saving of energy, because, as a result of the controlled blow-in, smaller volume flows are required and, with additional suction-extraction with the recording of the process heat, the room-cooling load and therefore the volume flow required can be further reduced. The apparatuses can be used for producing extremely moist and for producing extremely dry air states in the work zone of the machines. Areas of use are, hitherto, textile machines and ...
