Title: Rapid determination of microbiological activity - by adding DMSO to the foodstuff, cosmetic or pharmaceutical sample and analysing the di:methyl:sulphide produced in the gas phase
IPC: G01N33/487
Filed: 1991-11-05
Abstract: Process comprises mixing a sample in a closed container under (an)aerobic conditions, with dimethyl sulphoxide (DMSO) and then analysing the gas phase above the sample for its dimethyl sulphide (DMS) content. 0.1-2g Homogenised foodstuff are pref. mixed in a sample container with 1ml 5% DMSO soln. in water and the container sealed and shaken and kept under aerobic conditions or evacuated twice and gassed with N2 and incubated at 30 deg.C. 0.1-1.0 (esp. 0.1-0.5) ml of the gas phase are removed from the container and analysed by gas chromatography. The samples are incubated for 1-8 (esp. 2-3) hrs. at 30 deg.C. The gas chromatography is carried out with a column at least 2m long filled with Porapak R or a 10m glass capilliary column HP-5 each contg. a flame ionisation detector. The columns are kept at 160-180 or 40 deg.C and the detector and injector at 220 or 200 deg.C. The foodstuffs are minced meat, homogenised meat prods., starch contg. foodstuffs, foodstuffs based on milk or plant prods. such as spices. USE/ADVANTAGE - The process enables the microbiological activity in foodstuffs (esp. meat and meat prods.), pharmaceuticals, cosmetics and cell-free body liqs. to be rapidly determined. Satisfactory results are obtd. after incubating the samples for 2-3 hrs. under aerobic or anaerobic conditions, although the anaerobic conditions give a 40% higher DMSO rate of reduction and thus allow for greater accuracy which is esp. important in the case of foodstuffs where germ counts must be low. Aerobic conditions are preferred in samples in which germ counts are high

The signal (dc) coupling is specified to suit the input or output transistors with several gates. USE/ADVANTAGE - For satellite information or data signal transmission, with improve useful to interference signal ratio.
Patent DE-4138981-A1 (DE)
Inventor: HAAS THOMAS DR
IPC: C07B61/00
Filed: 1991-11-27
Abstract: The invention relates to a process for the preparation of 3-hydroxyalkanals having 3 to 12, in particular 3 or 4, C atoms, by hydration of the basic 2-alkenals with water in a homogeneous phase in the presence of an acidic catalyst. 
<??>The previously known hydration by means of mineral acids or carboxylic acids as catalyst results in poor space-time yields and/or poor selectivities. These disadvantages can be avoided when a dissolved acid/base buffer is used as catalyst which results in a pH of 2 to 5 in the reaction mixture and whose acid component and the corresponding base are present in the reaction mixture in an amount of 0.5 to 40% by weight in total. The preferred buffers composed of a lower monobasic carboxylic acid and a tertiary amine can be recycled in a simple manner.

Title: Inductive load driving system esp. for IC engine control - measures current shortly after switch=on and immediately after switch=off and calculates effective value, e.g. by averaging
IPC: F02B3/06
Filed: 1991-12-05
Abstract: The system for an inductive load drive consists of a driver circuit (60), a switch (20), a current gauge (40), a comparator (45) and a sensor (50). The driver circuit turns a switch on and off periodically to control the current flowing through the load (10). If the current measured with the gauge is lower than that set in the comparator, the driver increases the turn-on time of the switch. Otherwise, i.e. if the measured current is higher than that set in the comparator, the turn-on time of the switch is reduced. USE/ADVANTAGE - For positioning e.g. actuator for fuel metering in diesel engine or positioning throttle in spark ignition engine. Simple, precise.

Title: Laser beam distributor for medicine and biochemistry - consists of exciter source for producing oscillations, physical coupling mechanism for transmitting oscillations, two mirrors with connecting elements, and laser
Inventor: SOMMER ANDREI
IPC: B23K26/067
Filed: 1993-03-17
Abstract: The beam distributor has oscillations produced by the excitation source transmitted by the coupling mechanism to a first mirror (S1) which also serves as a deflection mirror for the laser beam. The beam from the mirror (S1) produces on a rotating second mirror (S2) an area-covering pattern corresp. to the oscillations of the first mirror (S1). The velocity of motion of the laser beam, in accordance with the oscillation motion of the deflector mirror (S1), is not zero at any point on the reflector mirror (S2). At the same time, the beam does not go beyond the rim of the second mirror (S2). USE/ADVANTAGE - Esp. for acceleration of ossification in case of bone fractures and/or for bio-stimulation of wound healing. It is more effective and simpler (and hence cheaper) than two possible alternatives involving respectively use of lenses and scanner system. Produces approximately homogeneous intensity over entire area subjected to radiation.
