Patent DE-4220259-A1 (DE)
Inventor: BOSSHARD WALTER
IPC: H02H9/04
Filed: 1992-06-23
Abstract: The protection arrangement contains (in a known manner) voltage-dependent dissipation elements (5 to 8), preferably metal-oxide varistors, a dissipation element being connected to each line (L1, L2, L3, N) of the power supply network. In the case of the present protection arrangement, the dissipation alternating current is intended to be monitored and a signal is intended to be triggered, in order to disconnect the device (1), which is to be protected, from the power supply network in the event of a limit value being exceeded. For this purpose, the protection arrangement has a measurement transformer (11) for detecting the dissipation alternating current (IA) flowing through the dissipation elements (5 to 8) in total. In addition, an evaluation apparatus (16) is provided which supplies a disconnection signal, which is dependent on the measured variable (IA), when the dissipation alternating current flowing through the dissipation elements after a dissipation surge current caused by an overvoltage has not fallen below a specific limit value. In this way, it is possible for the power supply to be disconnected only when the dissipation elements have become damaged as a result of overloading. <IMAGE>

Title: Real time auscultatory diagnosis of heart with audiovisual stethoscope - monitoring heart action of healthy and diseased hearts and analysing frequency spectrum characteristics to detect corresp. faulty heart valves
IPC: A61B7/04
Filed: 1992-09-22
Abstract: The method involves analysing frequency characteristics of a heart. Heart valve defects have virtually an individual frequency specific correlation.

Patent DE-4241451-A1 (DE)
Inventor: OESTE FRANZ DIETRICH
IPC: A62D3/00
Filed: 1992-12-09
Abstract: The invention relates to a process and devices for carrying out the process for purifying gases, exhaust gases, vapours and brines which are contaminated with undesirable chemical substances or are mixed with these at relatively high concentrations, by photocatalytic reactions which take place on the surface of catalysts. The catalysts (1) are situated in a fixed bed or a fluidised bed on catalyst supports. In the fluidised bed, the catalysts themselves can act as catalyst support. Catalyst supports and catalysts are situated in a closed system through which the substrate to be purified is passed. In the fixed-bed catalyst principle, the catalyst support/catalyst system continuously or discontinuously passes through a wash zone (12) for washing off the mineralisation products formed. The reaction is induced by photons of short-wave light of a wavelength between 250 and 400 nm. <IMAGE>

Title: Method for measuring the density variation of gases
IPC: G01N21/41
Filed: 1993-08-30
Abstract: The subject matter of the invention is a method for measuring the density variation of gases by optical means using a gas-density sensor, consisting of a measuring head and an evaluation and control device. The measuring head contains an optical emitter, a measuring chamber (3) and a signal-acquisition unit. The optical emitter (2) emits a measuring-light beam (2) which diverges sufficiently weakly and passes through the measuring chamber (3), while being displaced parallel to the original beam direction as a function of the gas density, since the measuring chamber (3) has two optical windows, arranged parallel to each other, in the form of plane-parallel plates, which are inclined with respect to the measuring-light beam by a particular non-zero angle. After it has passed through the measuring chamber (4), the measuring-light beam strikes the signal-acquisition unit (5), which is designed in the form of a linear array of optical fibres, the linear array being arranged in the beam-displacement plane in such a way that each individual fibre is struck perpendicularly by the measuring beam. <IMAGE>
