Title: Test leak probe for seal testing etc. - samples permeation of test gas through membrane to mass spectrometer
Inventor: KUHN ULRICH DIPL PHYS DR
IPC: G01M3/20
Filed: 1979-06-28
Abstract: A test leak probe is partic. for use in seal testing, partial pressure measurement, or calibration of leak testing device. It uses a completely different operating principle from that employed by conventional probes. It is suitable for wide use in laboratory as well as series testing applications. The principle involved is permeation. Permeation takes place through a membrane inside the probe. A definite gas throughput passes through the membrane and the test gas is then measured using a mass spectrometer. The membrane may consist of a plastics foil or a rubber or rubber-like material. For a Helium probe the membrane material may be polysulfon, polytrifluorochlorethylene, polypropylene, polyimile or polyethanediolterepthalate. tje first three of which result in short adjustment times.

When the substrate holder is moved to a new position another recess in the plate slab covers the opening (19).
Patent DE-2940422-A1 (DE)
Title: Transformation system for colour coordinate system - transforms digital chroma signal from rectangular coordinates into digital colour signal and saturation signal in polar coordinates
Inventor: KUHN FRANZ DR
IPC: H04N1/60
Filed: 1979-10-05
Abstract: The polar colour coordinate system is divided into quadrants, each identified by a number. The higher bits in the chrominance signal are evaluated first to determine the relevant quadrant. The equations for transforming the chrominance signal into colour signal and saturation signal for this quadrant are stored in a table memory. The colour signals for all quadrants are obtained from the quadrant number and the stored values. The amount of storage space required is reduced by subjecting the signals to a shift in position before addressing the table memory. This shift is reversed when the values are read from the table memory.. The system is fast, cheap and reliable.

Title: Inhalation appliance control unit - with second time dependent delay circuit and second threshold switch
Inventor: JEHMLICH KLAUS DIPL ING DR RER NAT
IPC: A61M16/00
Filed: 1980-03-05
Abstract: The Parent Patent No. 2936433 described an inhalation device with an atomiser for medicine and a time-dependent delay circuit. A second time-dependent delay circuit has now been added to feed the NAND-gate of a selector switch. The threshold switch in the pressure-dependent delay circuit is now connected in parallel with a second threshold switch to the respiratory pressure line. Both threshold switches feed the NAND-gate in this circuit. This improves the efficiency of the medicinal still further because the atomiser productivity can be altered independent of the time- and pressure-dependent switching of the aerosol flow.

Title: Cylindrical capacitor for charge particle passage - has perforated input shutter and slotted output shutter, whose slots are parabolic and outwards arcuated
Inventor: FROITZHEIM HERMANN DR
IPC: H01J49/22
Filed: 1980-04-17
Abstract: The cylinder capacitors with concentric section surfaces are particularly used as energy or mass dispersing elements in the spectrometry of charged particles, or as monochromator for such particles. The capacitor has an input and an output shutter, the input shutter (6) being in the form of a perforated shutter, while the output one (7) is in the form of a slotted shutter with a parabolic, outwards arcuated slot (9). The width of this slot in the output shutter corresponds to the diameter of the aperture (8) in the input shutter, this dia. being typically 1mm. The design of the capacitor safeguards practically no intensity loss. The capacitor construction is based on an observation that particles, entering the capacitor through a punctiform aperture, leave the capacitor over a parabolic section.

Title: Plug-and-socket connector for motor vehicle - couples brake switch to lamp circuit and to speed regulator to assist in ensuring security against accidental disconnection
Inventor: JUNKER HERIBERT
IPC: B60Q1/44
Filed: 1980-05-06
Abstract: In vehicles with speed regulator installations the brake switch (1) can be used to cancel the regulator setting when the brakes are applied. The necessity then arises of ensuring, as far as possible, that the lead (9) associated with the regulator does not become detached from the brake switch. One way of achieving the desired goal is to make two connector sections, one for the regulator (50) and one for the brake warning light (53,2). The brake switch (1) connector tongues each have two extensions (42,43; 40,41). The regulator connector is assembled first, and the longer tongues project through its housing. The brake light connector is then pushed onto the regulator connector housing. The two housings are shaped so that they cannot be assembled incorrectly on the brake switch.

Patent DE-3021629-A1 (DE)
Inventor: HARTMEIER WINFRIED DR
IPC: C12P1/00
Filed: 1980-06-09
Abstract: Living, fermentable yeast cells are prepared having an enzyme or mixture of enzymes coupled thereto. Enzyme coupling is carried out by contacting at least partially dehydrated living yeast cells with an aqueous enzyme solution to cause the yeast cells to rehydrate and a layer of enzyme to form on the surface of the yeast cells, and than contacting the rehydrated yeast cells with an enzyme-precipitating solution which optionally contains a cross-linking agent to cause the enzyme to become attached to the yeast cells. An aqueous solution of tannin is preferably the enzyme-precipitating solution and gluardialdehyde is preferably the cross-linking agent. Pepsin coupled to Saccharomyces yeast, when used to ferment grape must to produce wine, results in practically foam-free attenuation, quicker fermentation and better self-clarification. Saccharomyces yeast having amgloglucosidase coupled thereto may be used to ferment beer wort to produce a diet beer.
