Title: Test body with integrated temp. sensor - uses correction of measured dimension for temp. difference w.r.t. reference condition
Inventor: TRAPET EUGEN DR ING
IPC: G01B5/00
Filed: 1989-11-16
Abstract: A test body has a temp. related length variation detection system. Part of the temp. detection arrangement permanently installed in the body consists only of sensors read by a non-permanently associated evaluation system. During calibration, neither the true temp. nor a universal reference temp. is taken account of. The temp. indicated by the detection system, which corresp. to the reference condition, is taken account of. The measurement dimension is corrected by the measured temp. difference from the reference state multiplied by the expansion coefficient. USE/ADVANTAGE - For length and coordinate measurement systems, etc. Calibration and operator uncertainty are eliminated.

Patent DE-4014856-A1 (DE)
IPC: A61L11/00
Filed: 1990-05-09
Abstract: A mobile disinfection installation for the continuous disinfecting of hospital waste is described, it being possible for this installation to be arranged on a trailer, a mobile bridge or the like and thus be brought without difficulty to a place of use. The contaminated hospital waste is charged into a funnel, is passed from the latter through a cutting mechanism to a screw conveyor which is at disinfecting temperature, and is then passed onto a conveyor belt which discharges the waste, now reduced in volume and disinfected, which can then be disposed of in the same way as domestic refuse. By means of a logical distribution of space in the useful chamber of the disinfection installation, the components of the disinfection installation can be accommodated in the very limited space available, the compact installation producing excellent results because of the high power density of the individual components. <IMAGE>

Title: Control appts. for directional microphone signals - produces virtual directional characteristics with adjustable main receiving direction and degree of bunching
Inventor: SCHALLER WERNER DIPL ING
IPC: H04R3/00
Filed: 1991-01-21
Abstract: Calculation of the output signal (A) is achieved by multiplicative evaluation or weighting of the input signals (Ex) with control parameters (Px) by means of four quandrant mulitplication and final summation. This enables the control appts. to deliver a signal that corresponds to the freely selectable main receiving direction of a microphone and continuously alterable bunching degree. This occurs when the control appts. is fed with the necessary set of input signals (Ex) from real or simulated microphones, the spatial direction characteristics of which are orthogonal to one another. An arbitrary number of control appts. is formed into a unit with the same number of output channels. The number of output channels is independent on the number of input channels, all of which lead to the control appts. ADVANTAGE - Copes with virtual directional characteristics of complete units of orthogonal components including higher than first order.

Patent DE-4127840-A1 (DE)
Inventor: MORIMOTO YASUAKI
IPC: G11B7/007
Filed: 1991-08-22
Abstract: On an optical data substrate which represents a combination of an optical and a magneto-optical data substrate, data are recorded on top of each other both by means of both pits and in a magnetic layer. A suitable optical scanning device makes it possible to read simultaneously the data stored both by means of the pits and in the magnetic layer using a ligh beam. In order to suppress the crosstalk between the data signal (PS) obtained from the pits and the data signal (MS) obtained from the magnetic layer, an electro-optical modulator (EOM) periodically tips, parallel and vertical to the track direction, the electric vector (EV) of the light focussed on the data substrate (CD) at a substantially higher frequency than that of the data signal. At the output of a differential amplifier (DV) which generates the magneto-optical signal (MS) there is a low-pass (TP) for filtering out the rotation frequency of the electric vector (EV) from the magneto-optical data signal (MS). Application in magneto-optical recording and reproduction devices.
