Patent DE-4314757-A1 (DE)
Title: Hearing test method and device for screening
Inventor: WOLTER ANDREAS
IPC: A61B5/12
Filed: 1993-05-05
Abstract: In order to reduce the examination time of hearing tests according to the method of measuring acoustic emissions of the inner ear, use is made of acoustic stimulation sequences which, because of the separation, which is only short, between the individual stimulations lead to temporal superposition of stimulation and stimulation response signals. For this purpose, the signal-receiving components are configured such that they allow continuous detection and evaluation of this combined signal. The influence of the temporal superposition of the stimulation and response signals is taken into account and corrected by the use of numerical signal processing methods. By virtue of the high number of stimulation response signals detected in a short time, the interference components in the measurement result are effectively suppressed in the subsequent mathematical evaluation of the measured signals. With justifiable time expenditure, hearing tests can be carried out with this method even without special noise protection. This method is therefore also suitable for screening.

Patent DE-4325758-A1 (DE)
Title: Phase-modulated interferometer III
Inventor: DAMMANN EHRHARD
IPC: G01D5/26
Filed: 1993-07-31
Abstract: The invention relates to a phase-modulated interferometer for evaluating phase shifts on the basis of variations in optical wavelengths in the measuring arm of the interferometer. The object of realising a phase-modulated interferometer which generates the sin-cos signals which are usual in length measuring systems and makes them available as conventional interface, is achieved according to the invention in conjunction with sinusoidal driving of the phase modulator (11) by admixing with the split superimposed signal from the reference arm (12) and the measuring arm (13) in a separate and mutually parallel fashion in each case sinusoidal signals of the form sin [(2n-1) omega t] and cos (2m omega t) which are coupled to the drive signal of the phase modulator in a phase-locked and frequency-locked manner. After filtering by means of two low-pass filters (51, 52), the conventional quadrature signals are available at an interface (5). The invention is preferably used for precision length measuring systems based on a heterodyne evaluation. <IMAGE>

Title: Liq. esp. water treatment device - has magnetic field-forming plates forming tortuous flow path
Inventor: SAUER ROLF G
IPC: C02F1/48
Filed: 1993-10-26
Abstract: A liq. (esp. water) treatment device has a flow-through housing (1) contg. a series of spaced plate-like bodies (4,5) which are aligned to oppose the main flow direction and which comprise two alternate sets. One set comprises through-flow bodies (5) which have at least one passage (6) in the region of the main flow direction, have outer edges seated on the housing inner wall (7) and produce magnetic field-forming effects. The other set comprises baffles (4) which divert the liq. flow from the main flow direction towards the housing inner wall (7) and then allow liq. flow to the next through-flow bodies (5). The novelty is that the baffles also produce magnetic field-forming effects and their outer edges are only partially seated on the housing inner wall. USE/ADVANTAGE - Esp. for attachment to a tap to prevent limescale formation in water using or consuming equipment. The device has increased efficiency independent of its size so that it can be dimensioned to meet various requirements while maintaining almost constant scale preventing power.

Title: High electric DC currents polarity reversing circuit
Inventor: WIRTH HARALD
IPC: H01H33/00
Filed: 1993-11-25
Abstract: The two contact bridges (3,4) are attached to a linearly movable plunger (5) and are formed as two-armed parallel cross-bars. The first arm of each cross-bar is connected to an input terminal and the second arm is connected to an output terminal. The arms of both cross-bars (3,4) engage in the space between stationary contacts. One arm of each bar fits between two same sign poles (35-36,45-46). The other arm fits between two opposite sign poles (37-38,47-48). Between each contact arm and each stationary contact there is a metallic contact element (31..34,41..44) via which the contact bridging current flows. To reverse the plunger (5) at both end positions, there is a piston-cylinder device (7,8). This is positioned such that the four contact elements (31,33,41,43) in each end position in the current path are compressed between the cross bar arms and the stationary contacts in a contact system.

Patent DE-4445686-A1 (DE)
Inventor: LISEC THOMAS DIPL ING
IPC: F15C5/00
Filed: 1994-12-21
Abstract: The invention concerns a valve arrangement, in particular for use in pneumatic control systems. Since pneumatically actuated adjusting components have a given leak rate, the control valve (pilot valve) has to remain permanently in the open state in order to maintain the adjusting component in the deflected position, which requires high retaining capacities. In contrast, the valve arrangement according to the invention requires energy only for switching from one state to the other and can maintain the selected state without power. This is achieved by means of an inlet valve and an outlet valve, at least the inlet valve being a microvalve having a rest position in addition to the open and closed positions. In the rest position there is a gap between the closure member and the microvalve seat. The dimensions of the gap are such that the leak rate of the adjusting component is equalized by gas flowing through the gap. No energy is consumed in the rest position, which the valve adopts when no external forces are applied. In a particular configuration, the valve closes automatically when a specific differential pressure is applied.
