Title: Tensioning rail
Inventor: BALLHAUSE LUTZ DIPL ING
IPC: F01L1/02
Filed: 1993-03-30

Patent DE-4317187-A1 (DE)
Title: Novel method for gas quantity measurement (gas meter)
Inventor: KOLB HANS PROF DR
IPC: G01F15/00
Filed: 1993-05-22
Abstract: The method presented here requires no external energy to produce the measured variable. This energy is extracted from the flow energy of the gas to be measured. There are no moving parts in the measuring chamber. The method according to the invention requires the excitation of acoustic oscillations inside a measuring chamber by means of parts which are capable of oscillation being flowed around inside the chamber by the gas stream. This arrangement has to be conceived such that conclusions can unequivically be drawn as to the flow velocity of the gas to be measured, from the mixture of sounds or noise produced. In the case of a known flow cross-section, the gas quantity which has passed through per unit time can then be directly determined. This measuring method is above all energy-saving as a result of the fact that the measured variable does not have to be produced by the use of external energy from a battery. The service time of the measuring apparatus without battery change is therefore very high.
Patent DE-4318386-A1 (DE)
Title: Displacement sensor for a moving element
Inventor: SANO MASASHI
IPC: G01D5/36
Filed: 1993-06-01
Abstract: An optoreceiver which obtains light from a light-emitting device through slots in a rotating disc is provided with a first, a second and a third photodiode. Using the output signal of the second photodiode as reference value, the output signal of the first photodiode is compared with the reference value and pulsed by means of a first comparator, and the output signal of the third photodiode is compared with the reference value and pulsed by means of a second comparator. Because the output signal (the reference value) of the second photodiode decreases in the same way when the output signals of the first and of the third photodiode decrease by virtue of a decrease in the quantity of light of the light-emitting device, in such an optoreceiver no deviation ever occurs in phase difference between the output signals of the first and second comparators. <IMAGE>

Title: Appts. for enrichment of a gas in a liq., esp. for oxygenation of blood and substitutes
Inventor: BAUMANN GERT PROF DR MED
IPC: B01F3/04
Filed: 1994-03-02
Abstract: A device for enriching the content of a gas in a liq. has a component (806) in the form of a hollow body rotating at high speed. A thin film of liq. is formed on the inner surface (806b) of the body as a result of centrifugal force, in the presence of the gas. An inlet (803) and outlet (811,813,12) passage for the liq. are so arranged that the part of the surface onto which the liq. is applied is at an axial distance from the outlet passage.  The hollow body is a vertical drum rotating about its axis of symmetry. The liq. is introduced onto the lower part of its inner surface, whilst the outflow passages are located near its top. The gas is introduced through a passage (10) near the liq. inlet, and the liq. and gas come into intimate contact with each other as they enter. The base of the drum (806a) is conical or convex, and the liq. is introduced onto its centre after passing through the gas in the form of droplets. A ledge (806d) protruding into the drum surface below or at the outflow passage determines the thickness of the film which is formed. At least part of the inner surface of the drum is of plastic material, esp. 'Piacryl' (RTM).
