Title: Fatty acid amide(s) prepn. - from crude fats and oils by reacting with amide forming reagents, useful as lubricant additives
Inventor: FRISCHE RAINER DR
IPC: C07C231/02
Filed: 1990-06-15
Abstract: Recovery of amides of natural fatty acids from fats and oils is claimed, in which crude fats and oils opt. in a suitable solvent and with addition of suitable catalysts and antioxidants are reacted directly with amide forming reagents producing fatty acid amides which are opt. purified. Pref., the crude fats and oils contain a high content of functional (unusual) fatty acids. Crude oils and fats which can be used are euphorbia oil, linoleic acid or oleic acid rich sunflower oils, esp. the "high oleic" type, rape seed oil, esp. erucic acid rich rape seed oil, purge nut oil, (hydrated) ricinica oil, linseed oil, olive oil or sea animal oil such as fish or whale oil. 1 deg. and 2 deg. (cyclo) aliphatic, aliphatic-aromatic or aromatic mono amines or diamines can be used as amide-forming reagents, and esp. 1,2-diaminoethane or 1,6-diaminohexane. The solvent used is toluene, xylene, or petroleum ether. The raw material is converted into the amide at 20-300 deg.C. (esp. 50-200 deg.C.). The conversion occurs in an inert atmosphere of nitrogen or argon. The catalyst is ammonium chloride or p-toluene sulphuric acid.  The antioxidant is ascorbaic acid or glucose. USE/ADVANTAGE - All crude oils and fats can be directly used as raw materials without extensive purification processes.  High purity amides of fatty acids can be obtd. in direct conversion.

Title: Reproducing colour signals in VTR - has colour difference detection circuit controlling electronic switch assigned to comb filter
Inventor: DILGER RALF
IPC: H04N9/64
Filed: 1990-07-19
Abstract: The method is applied to colour pictures recorded on a video tape whose colour signals are transmitted via a comb filter (2) in the transmission channel (1). A colour signal (8) direct from the filter (2) is compared with a preceding signal (12), delayed by a given amount, from the delay line (11) of the filter (2) and a difference signal (26), dependent on the difference between the signals (8, 12), is produced. While the difference signal (26) exceeds a predetermined threshold (SW1) the filter is switched off when a horizontal edge is detected. This filter operates to remove cross-talk during scanning of the sides tape but can itself course two line false colour stripes. It is therefore switched out when this arises.  USE/ADVANTAGE - Reduces interference resulting in error in colour. Small compact inexpensive circuit which can be easily added to video recorders during mass prodn. process.

Title: Liquid level sensor with pressure tight sealed immersion tube - has pressure sensor sealing tube top and float body exerting pressure greater than that of enclosed gas
Inventor: WEYHMUELLER HELMUT DIPL ING
IPC: G01F23/60
Filed: 1990-07-25
Abstract: The level sensor includes elements in a pressure tight immersion tube (10). A pneumatic pressure sensor (12) seals the top of the tube and a float body (34) is arranged below the pressure sensor with a drive connection to it. The buoyancy force of the float body is selected to be greater than the force exerted on the pressure sensor by the enclosed gas. The pressure sensor converts the detected pressure into a displacement which acts on a swtiching element (20) via. a pin (26). ADVANTAGE - Eliminates failure conditions e.g. when membrane seal fails, to remain operational under all conditions.

Patent DE-4103082-A1 (DE)
Inventor: KAISER WILHELM
IPC: B21C37/28
Filed: 1991-02-01
Abstract: In a process for the hydrostatic shaping of hollow bodies (21) of cold-workable metal and in a device for implementing the process, pressurised liquid is fed from outside into the hollow body (21) inside a shaping chamber (17) of a swage (16).

Title: Thermomagnetic motor using low temp. heat sources - has extra magnetic field doubling generated torque and heat recycling between cold zone and heated zone
Inventor: FUERTHALLER WALTER
IPC: H02N10/00
Filed: 1991-10-10
Abstract: A thermomagnetic motor has a rotating ring of nickel iron alloy, a heat source for a portion of the ring, an adjacent pole pair with pole shoes giving an axial magnetic flux across a portion of the ring and a cooling medium into which the heated portion of the ring subsequently dips. Within the cooling medium another magnetic field provides a radial flux in the ring. This effectively doubles the torque generated. Heat that would be given up by the ring at the cooling medium is recycled to the portion about to be heated up by means of a fluid. A practical arrangement has a fluid circulated within the ring in an opposing direction with impellers. ADVANTAGE - Improves efficiency of motor that previously had no practical use.

Filed: 1992-01-24
Abstract: A power integrated circuit (1) has either a vertical power component (2, 3) and a control circuit (4) for driving the vertical power component (2, 3), or only vertical power components (2, 3). In order to prevent the switching processes of the vertical power component (2, 3) from affecting in an undesirable manner the control circuit (4), an etching stopping layer (12) is applied underneath the semiconductive area where the control circuit (4) is to be produced, during the power integrated circuit (1) manufacturing process. The control circuit (4) and the vertical power component (2, 3) are then produced by usual processing steps, and a front protective layer and a rear masking layer are applied on the wafer. Once the mask is structured in order to create an opening underneath the etching stopping layer (12), the backside of the substrate is etched until the etching stopping layer (12) is reached. Alternatively, once the processing steps for producing the vertical power components (2, 3) have been carried out and once a lateral insulating layer (13) has been applied between the vertical power components, a front protective layer and a rear masking layer are produced, then the rear masking layer is provided with a recess underneath the lateral insulating layer (13) through which the backside of the substrate is etched until the lateral insulating layer is reached.
