Title: Measuring blood pressure by oscillation method - forming general envelope curve from pulsed pressure waves from computer
Inventor: KUENECKE PETER DIPL ING
IPC: A61B5/0225
Filed: 1989-12-18
Abstract: A binding (1) applies a counter-pressure to interrupt the pulsating pressure waves of the blood flow. These pressure waves modulate the variable external pressure and are converted to electrical signals by a pressure sensor (8). The latter continuously detects changes in the external counter pressure dependent on the patient's diastolic as well as systolic blood pressure values. The amplitudes of the signals of at least two sequential continuous variations of the external counter-pressure are made simultaneously available by electronic memories. These amplitudes are combined to an electrical complete signal under creation of a common envelope curve. At least one blood pressure value to be displayed is formed from this complete signal. ADVANTAGE - Reduced change in measurement result from artefacts.

Freely selectable connecting rod suspension on the crank drive, result in varying reverse times of the pistons. This permits compression and expansion volumes to be of different sizes. USE - IC engine with reciprocating arcuate pistons.
Patent DE-4003417-A1 (DE)
Inventor: KOBLITZ RUDOLF DIPL ING DR
IPC: H03J7/04
Filed: 1990-02-05
Abstract: Analog circuit parts in an integrated circuit, for example filters, can be equalized by a control current by equalizing an additional reference circuit part, whose equalization must be verified externally, with this control current. By using a suitably designed horizontal frequency oscillator whose equalization must also be verified, this reference circuit part can be dispensed with even in known TV receivers. Using additional control circuits in the integrated circuit, fine equalization of the various circuit parts can be carried out automatically by adding a small correction control current to each control current. As a result, the control circuits are free from problems related to background noise, interception range and component tolerances. Equalization of analog bipolar or CMOS integrated circuits.

Title: Fluid flow speed measuring appts. - has two excitation coils on outer surface of joining pipe assigned to ends of locating coil
Inventor: SHINDO MITSUO
IPC: G01F1/22
Filed: 1990-09-14
Abstract: A movable part (5) of non-magnetic material is installed in a joining pipe (1) in which a fluid flows. A locating coil (11) is wound around the pipe (1). A pair of excitation coils (12A, 12B) is installed at a zone near the ends (11a,11b) of the locating coil. The excitation coils simultaneously generate magnetic fluxes of the same strength but in opposite directions upon application of h.f.  excitation voltage of alternating waveform. A sec. magnetic flux is generated corresp. to the position of the movable part. When this sec. magnetic flux is interlinked with the locating coil, a voltage of alternating waveform is generated in the latter. A phase difference between the waveform of this voltage and that of the excitation voltage arises according to the position of the movable part.  The position of the latter is derived on the basis of the phase difference signal. ADVANTAGE: Accurate yet simple construction.

Title: Transfer of cathodic current to wire in galvanising process - in which pressurised air flows through swivelling contact arm to circulate around contact point and clear amorphous metal build=up
Inventor: POETTER ROBERT
IPC: C25D7/06
Filed: 1990-12-22
Abstract: Process for transferring cathodic current to a wire passing through an electrolyte in a galvanising plant. A wire passing horizontally through the electrolyte is contacted by a swivelling arm through which negative current is applied to the wire. Normally a build-up of amorphous metals occurs on the contacting surfaces which affects reliability of contact and ultimately the surface treatment quality. In the new process, air under pressure is forced through the swivelling arm to circulate around the contact point between arm and wire. Electrolyte is purged from the area of contact and a metal build-up is prevented. Pref. a contact arm formed by a thin-wall hollow cylinder is pivoted on a shaft., At the remote end of the arm is a contact head which rests on the wire at 60 deg.C and has a wire guiding groove into which an air duct enters. USE/ADVANTAGE - Used in a wire galvanising process, prevents amorphous metal build-up, improves contact between wire and cathode to give better surface quality.
