Title: Device for volumetric measurement on human or animal limbs
Inventor: GUTMANN JUERGEN DR ING
IPC: A61B5/103
Filed: 1985-05-07
Abstract: Volumetric measurements on human or animal limbs are carried out in medicine as follow-up therapy and in testing drugs. The aim thereby is, e.g., to establish whether an oedema is being displaced or whether blood is sinking in the limbs. This measurement is carried out, e.g., by sectional determination of the extent and calculation using a mathematical model of Kuhnke, by measurement of the silhouette followed by mathematical evaluation, or by an overflow volumenometer meter in which the limbs are immersed in a vessel filled with water and the amount of overflowing water is determined. The concept of the invention consists in replacing measurement of the water displacement by measurement of the displacement of electrical field lines in an electrolytic trough. The measurement arrangement consists essentially of an electrically non-conductive tub in which there are an electrolyte solution and two electrodes. The change in the resistance upon immersion of the limbs is determined using means known per se. The measurement utilises the circumstance that the specific resistance of human or animal tissue is substantially higher than the specific resistance of the electrolyte solution. An error caused by the shape plays a subordinate role in examinations of longitudinal sections, since the extremity retains its principal shape. The figure shows the simple measurement arrangement described. By arranging a plurality of electrodes ... Original abstract incomplete. <IMAGE>

Title: Low-loss switched-mode regulator which is supplied with a variable current
Inventor: WARNEMUENDE GUENTER DR
IPC: H02M3/156
Filed: 1986-03-21
Abstract: Various variants are specified of a switching low-loss electronic regulator having an inductor coil as an energy store for producing a fixed DC voltage (supply voltage) with a variable, impressed supply current for the regulator. An important field of application is two-conductor technology (for example the 0...20 mA system), in the case of which a high voltage with a low current or a low voltage with a high current is frequently available for an additional user (for example a digital display without any additional energy). The switched-mode regulators which are specified here achieve the object which is thus placed of reducing the input voltage requirement at high currents by controlling a switching element S using a Schmitt trigger or comparator into which the switching element can also be integrated, as in the circuit alongside, in such a manner that if the output voltage ua which is compared with the reference voltage ur is too low (high), the switching element is switched off (switched on). Stability of the circuit is achieved by means of the important capacitor C2, and rapid switching over by means of the dynamic positive feedback C5. The capacitors C1 and C2 smooth the input voltage and output voltage. <IMAGE>
Patent DE-3613761-A1 (DE)
Title: Safety valve
Inventor: RUEDIGER HORST DIPL ING
IPC: F16K39/02
Filed: 1986-04-23
Abstract: The invention relates to a safety valve with an inlet line 3 and an outlet line 10 for a pressure medium, a valve housing 5, a valve seat 8, a movable valve body 7 and a spring 6 loading the valve body. In order to keep the opening pressure of the safety valve independent of the pressure acting in the outlet line, a safety valve controlled by absolute pressure is proposed according to the invention. The inlet pressure of the safety valve acts via a compensating line 4 on the inner space of the diaphragm bellows 1. A force thus achieved opens the safety valve against a spring force. As the outer space of the diaphragm bellows 1 is connected to a constant ambient pressure, the safety valve always opens at the same absolute pressure. Suitable dimensioning of the diaphragm bellows 2, the inner space of which is likewise connected via the compensating line 4 to the pressure in the inlet line, ensures that the opening pressure of the safety valve is independent of the pressure in the outlet line 10. <IMAGE>
Patent DE-3621679-A1 (DE)
Title: Method and device for selecting the channel suitable for reception in wireless microphone systems
Inventor: HOPFENSITZ RAINER DIPL ING
IPC: H04B7/12
Filed: 1986-06-27
Abstract: In this method and device, it is proposed to generate an additional frequency as pilot tone in the receiver and to superimpose this frequency onto the AF signal to be transmitted. At the receiver end, the disturbance of this pilot tone frequency is detected, either by generating an identical reference frequency so that the degree of correlation can be measured or by distortion measurement and comparison of the distortion with an undistorted signal on the same transmission link. Depending on the result, the channel with the most undisturbed pilot tone is connected; this priority condition is cancelled only when the level of a receiving channel drops below the squelch minimum. In this case, the other channel is connected independently for measuring the degree of correlation.

Title: Tablet dispenser
Inventor: GALLINA FERENC DIPL ING
IPC: B65D83/04
Filed: 1986-09-25
Abstract: A tablet dispenser for the individual dispensing of tablets, consisting of a container part and an outer part. By pressing on the container part, the latter moves downwards in the outer part into the dispensing position, it being possible for the first tablet lying in the collection groove to drop out through the outlet aperture. At the same time, the collection groove tapers in front of the second tablet due to the tip of the blocking spring, as a result of which said second tablet is blocked. Due to the web which projects upwards from the bottom of the outer part and whose upper region is of sawtooth-like construction, the supply of tablets is moved during the dispensing actuation. The return into the basic position takes place by means of a restoring spring moulded onto the container part.
