Abstract: The invention is related to a feedback method and apparatus for a capacitive differential pressure transducer. According to the method, a pressure-transducing conducting diaphragm (1) forming a first, moving electrode of the transducer capacitances is kept in a force balance state by means of a pulse train signal applied to a fixed electrode (2, 3). According to the invention, the diaphragm (1) is kept stationary in a geometrically constant state and a desired electric potential is applied to said diaphragm (1), said pulse train signal is applied to at least two of said fixed electrodes (2, 3), or alternatively, sets of fixed subelectrodes so that the signals applied to said separate electrodes (2, 3) or sets of subelectrodes are at opposite polarities referenced to the electric potential of the pressure-transducing diaphragm (1) for at least a portion of the measurement duration, and the signals applied to said separate electrodes (2, 3) or sets of subelectrodes are of equal amplitude at least for each pair of electrodes (2, 3), and the same pulse train signal is simultaneously used for both establishing the force balance and performing the capacitance measurement. According to a preferred embodiment of the invention, changes in the dielectric coefficient of the transducer fill medium are compensated for by altering the pulse amplitude, pulse width or pulse rate depending on the primary modulation method used in the feedback control.

IPC: C04B33/04
Filed: 1993-04-23
Abstract: A method for preparing a time-stable, low viscosity, pumpable high solids aqueous bentonite slurry which has good application properties upon dilution and use. An aqueous solution of at least first and second salt components is prepared in which there is dispersed at least 8 % by weight of the resultant slurry of a powdered bentonite. The first salt component is selected to give if used alone an acceptably low viscosity to the slurry at said high solids and at least good application properties upon the dilution and use. The second salt component is selected to act in combination with the first salt component to substantially further decrease the acceptably low viscosity at a specified high solids content or to enable increase of the solids content while maintaining the acceptably low viscosity, while not substantially impairing the application properties. The high solids pumpable slurry product is also claimed.

Title: Polarized electromagnetic relay
Inventor: STADLER HEINZ
IPC: H01H51/22
Filed: 1994-03-16
Abstract: The relay comprises a base (1) with stationary mating contact elements (11, 12, 13, 14), a coil (5), a permanent magnet (4) and also a rocker armature (3) which is arranged between the coil and the base, is connected to movable contact elements  (21,  22,  23,  24)  and is mounted on the base by means of bearing strips,  the bearing  strips  simultaneously  serving  as  electrical connections for the movable contact elements. The bearing strips (25, 26) are secured to the bearing supports (15, 16), which are designed as connection elements, of the base in planes extending at right angles to the basic plane of the base. As a result, the contact separation can be set with low tolerance even during production, and it is not dependent on tolerances of  the individual parts.   This structure consequently permits non-proble-matic, cost-effective production of the individual parts and accurate assembly without the requirement of subse-quent adjustment.
