Patent DE-2830956-A1 (DE)
Title: Water activation system - exposing water molecules to strong magnetic and electric fields
Inventor: SCHWAMM ERNST DR MED
IPC: B01J19/08
Filed: 1978-07-14
Abstract: When water molecules are exposed to the action of a strong magnetic field between two permanent magnets, their dipole moment can be affected so that the molecules become activated. In that state they can cling more strongly to other molecules and ions of organic and inorganic matter and can cure surface tension problems. Apart from the permanent magnets, a Au electrode, contacting the water surface is connected to the positive pole of a d.c. source, and a Pt electrode in the wall of a glass tank forms the negative pole. A crystal at the water surface was kept at 18 degrees C to emit IR radiation in the water. Magnetised water was used to water plants and resulted in more luxurious growth.

Title: Leakage detector system for testing light gases - has high vacuum pump operated at constant compression rate irrespective of existing vacuum conditions
Inventor: HENNING HANS-HEINRICH DIPL PHY
IPC: G01M3/20
Filed: 1979-06-15
Abstract: The leakage detector is operated in conjunction with a mass spectrometer, in front of which is connected a high vacuum pump whose compression capacity is lower for light than for heavy gases. In front of the vacuum pump is connected an advance evacuation pump, with a testing gas line opening between the two pumps. The high vacuum pump (3) is operated independently of the prevailing advance evacuation pressure, and maintains a constant compression capacity. An inert gas is supplied into the testing gas line, in order to maintain the constant compression capacity of the high vacuum pump. If a diffusion pump is used this capacity is kept constant by a heating control. The high vacuum pump may be in the form of a turbo-molecular vacuum pump, in which case the compression capacity is kept constant by speed control.

Title: Electro-acoustic radiator plate - has magnetostrictive elements giving high efficiency by avoiding bending oscillations
Inventor: KRATYSCH GEORGIJ SERGEJEVITSCH
IPC: B06B1/08
Filed: 1979-07-13
Abstract: A number of magnetostrictive oscillator elements having a rectangular cross-section with sides (6,7) are welded with their frontal faces (3) upon a radiator plate (1). The angle between the sides of the elements and the plate has an effect on various parameters of the ultrasonic emission. If all the angles are the same-though no smaller than 15 and no larger than 75 degrees. max efficiency of the radiating energy is achieved. If the inclination angles of individual elements differ from each other favourable effects can be achieved. The illustrated positions produce max. evenness of the radiated energy over the whole surface of the radiator plate (1) which often improves the work quality, in cleansing or emulsion baths.

Title: Blood substitute colloid soln. - contg. reaction prod. of water-soluble colloid e.g. oxy-poly:gelatin and an aliphatic per:fluoro cpd. e.g. per:chloro-hexyl-acetyl chloride
Inventor: KOTHE NORBERT DIPL CHEM DR
IPC: A61K31/755
Filed: 1979-10-04
Abstract: New colloid solution suitable for use as a blood substitute is obtainable by reaction of a physiologically tolerable, water soluble colloid with an aliphatic perfluoro cpd. and adjustment to an isotonic electrolyte content. Used as a substitute for blood or plasma for transfusions when high blood losses have to be replaced. Thon osmotic and cotic pressure and flow properties of the colloid solution are closely similar to those of blood. The solution caters for transport and exchange of, but does not react with, oxygen and CO2. It has no adverse effects on the constituents of natural blood, and facilitates the regeneration of blood components. The components of the solution are eventually excreted from the body.

Title: Ultrasonic head for Doppler flow measurement - has piezoelectric vibrator half-wave plate and low temp. coefficient path
Inventor: KOENIG BEATE DR
IPC: G01F1/66
Filed: 1980-04-08
Abstract: An ultrasonic head with an electroacoustic tranducer performs ultrasonic flow measurement operating on the Doppler principle. A composite body (2,3) consisting of a half wavelength filter plate and a piezoceramic vibrator is placed in a housing before a damping body. The arrangement eliminates the effects of temp. variation on the speed of sound in the measurement medium. The head has an output path (7) of a material with a low temp. coefficient of speed of sound. The end surface (8) of the output path is inclined to the main axis of the sound lobe radiated from the composite vibrator. If the head is inserted in a measurement tube the inclination of the end surface (8) ensures that it stands in contact with the measurement medium.
