Patent DE-4302977-A1 (DE)
Title: Hydraulic plant with pump or motor - generates 180 deg. phase-displaced compensation wave against uneven surface of pressure medium flow
Inventor: WEIGLE DIETER DIPL ING
IPC: F04C15/00
Filed: 1993-02-03
Abstract: The hydrostatic engine (10) has a pressure sensor (14) in its intake or discharge section, to measure the amplitude of the uneven surface of the pressure medium flow. The generated signal is processed in a controller (C) with associated intensifier (A). The controller operates a volume compensator (VC) e.g. a piezo compensator, which is located on the high pressure side. The compensator has action against the pressure medium flow, and transmits a compensation wave of the same instantaneous amplitude, which is phase-displaced through 180 deg., against the uneven amplitudes. An additional pressure sensor (15) is located downstream of the volume compensator, to detect any residual unevenness. ADVANTAGE - Provides for noise reduction. Uses simple method for very effective pulsation damping.

Title: Pressure-medium-controlled drive with encapsulated springs
Inventor: BENDER HANS
IPC: F16K31/126
Filed: 1993-02-24
Abstract: In pressure-medium-controlled drives whose drive rods are moved in the one direction by diaphragm or piston force and in the other direction by spring force, springs are fitted which are under preloading. In the known drives, the preloading is produced during the assembly by fitting together the housing by means of long screws or by means of fixtures. In the event of careless dismantling, the preloading force can be released and endanger the fitter. In the novel drive, safety is to be increased. The springs (5) are arranged in cages (1, 2, 3, 4). The cages are designed in such a way that they permit the compressing of the springs (5) by diaphragm or piston force within the stroke range but prevent unintentional relaxation if the drive is dismantled. The drives are suitable for control and operating tasks, especially in the actuation of valves. <IMAGE>
Patent DE-4309148-A1 (DE)
Inventor: DRESCHER NORBERT DR
IPC: G11B20/18
Filed: 1993-03-22
Abstract: The invention pertains to a process for realizing high-availability disk storage through redundant combination of individual drives (18a..c). Thus, the control units (16a..c) take over the generating of correction information, which is either transferred, under CPU control, from the control unit (16a) of the target drive (18a) to the control unit (16c) of the redundancy drive (18c) or is transferred, under control of the control unit (16a), directly to the control unit (16c) of the redundancy drive (18c). This yields particular advantages in systems having separate CPU bus (13) and I/O bus (15), which are coupled by a bus coupler.

IPC: F16H55/30
Filed: 1993-04-20
Abstract: Wheel, especially a belt or chain wheel (1), which is composed of wheel sectors (2A, 2B) having peripherally on the end face annular grooves (8, 9), in which are arranged annular, axially contractable clamping rings (4, 4A, 4B), by means of which the wheel sectors (2A, 2B) are held braced together and the wheel (1) is to be fastened thus on a shaft (3). The wheel (1) consists of at least three identical or approximately identical wheel sectors (2A, 2B). One of the clamping rings (4) is a closed ring which is fixedly connected to an inner ring (6) via a disc (5) located on the end face.

Title: Tetrahydrofuranylpropionic acid, a process for its preparation and use thereof
Inventor: GRAEFE UDO PROF DR
IPC: C07D307/16
Filed: 1993-05-19
Abstract: The invention relates to a novel tetrahydrofuranylpropionic acid which is obtained by chemical routes as a subunit of the pamamycin antibiotic complex. To do this, the pamamycin complex is first prepared by fermentation of a microorganism, Streptomyces aurantiacus JA 4570. Pamamycin is then hydrolytically cleaved and the tetrahydrofuranylpropionic acid is isolated in pure form or in a mixture with a homologous minor component by the use of chromatographic methods. On account of the known suitability of fatty acids as bioactive compounds or constituents of pharmaceuticals, this novel carboxylic acid is potentially very highly suitable for the production of antiatherosclerotics, hypocholesterolemics, anti-inflammatories and as a chiral starting product for the synthetic preparation of pharmaceuticals. The novel tetrahydrofuranylpropionic acid is furthermore able in the form of suitable derivatives to promote the passive transport of organic cations and thus potentially to improve the bioavailability of cationic therapeutics.

Title: Conversion of measured signal using Pirani circuit - using bipolar transistors to produce logarithmic function based on variation of base-emitter voltage w.r.t. collector currents
Inventor: STOCKER RUDOLF
IPC: G01D3/036
Filed: 1993-07-19
Abstract: The method involves converting a measured signal (x,U), which is represented to at least a first approximation by values of interest (y,p): y = k1.(x<2>-kN<2>)/(kZ<2>-x<2>), where y is a value of interest, x is the measured signal, and k is a constant. Then the equation: ln y = prop.((ln(x-kN)-ln(kZ-x))) is applied, where prop. stands for 'proportional'. This function is realised approximately by using at least two bipolar transistors and exploiting the dependence of their base- emitter voltage on the collector currents to produce an output signal y' = ln y. The transistors are closely thermally coupled and their blocking voltages are balanced. USE/ADVANTAGE - Circuit for mounting in sensor head e.g. in Pirani hot- wire vacuum meter for measuring pressure. Smoother output characteristic for improved accuracy.

IPC: H04R19/00
Filed: 1993-12-10
Abstract: The electromechanical converter e.g. a microphone, has a rigid electrode in the form of a plate (20). It also has an elastic electrode in the form of a membrane (10) arranged next to the plate (20). The membrane (10) is movable relative to the plate (20) by a mechanical input signal (28), e.g. sound pressure (p) or a membrane acceleration. Both electrodes (10,20) have electrically conductive surfaces (13,14;23). An electric operating voltage (UT) is applied to these surfaces and an electric operating signal due to the membrane acceleration is provided at them. At least the conductive surface of one of the electrodes (20) has an electrically conductive point (24). At least the conductive surface of one electrode (10) has two electrically insulated zones (13,14). The voltage (UT) is only applied to the one of these zones (13) which bears or cooperates with the point (24). A control voltage (UY) is applied between the other zone (14) and the surface (23) of the opposing electrode (20). This generates an electrostatic attractive force (FE) between the electrodes (10,20) and the membrane (10) is drawn so near to the plate (20) that a tunnel current (IT) flows between the surfaces (13,23) of the two electrodes (10,20). This current (IT) generates the output signal (UY) to be analysed, via an electronic amplifier (33).
