Patent DE-19649895-A1 (DE)
Inventor: SCHELGES HEIKE
IPC: C11D1/86
Filed: 1996-12-02
Abstract: This invention concerns foaming aqueous compositions of body-cleansing agents containing anionic surfactants (A) with a strong foaming action and alkyl-(oligo)-glucosides (B) which are easily tolerated by the skin, and a combination of a zwitterionic surfactant (C), e.g., a betaine surfactant, and an ampholytic surfactant (D), e.g., a cocoamphoglycinate, to improve foaming properties and viscosity. Combining betaine and ampholytic surfactants yields a particularly creamy foam structure, consisting of particularly tiny bubbles when using said compositions.
Patent DE-19650722-A1 (DE)
Inventor: JEON SEONG HO
IPC: G03F7/20
Filed: 1996-12-06
Abstract: A method and an apparatus used to form a pattern on a wafer uses elliptically or circularly polarised light. The light may be determined by use of equations induced in accordance with the vector image theory and deriving S and P-polarized components (S com and P com ) (these components are perpendicular to and parallel to a meridional plane, respectively) of polarized light having x and y-directional components entering an illumination mask, thereby preventing a contrast difference resulting from a contrast gap generated in the conventional linear polarization method, namely, an inconsistency between the longitudinal direction of the pattern and the polarization direction.

Patent DE-19709652-A1 (DE)
Title: High speed power semiconductor diode
Inventor: LUTZ JOSEF
IPC: H01L29/868
Filed: 1997-03-10
Abstract: A high speed power semiconductor diode has a lightly doped first conductivity type middle layer between a heavily doped first conductivity type first outer zone and a second conductivity type second outer zone including a p-n junction, the middle zone thickness and doping concentration Nd being chosen to achieve a defined blocking voltage at a voltage Ur and the entire middle zone containing recombination centres produced at least partially by accelerated particle irradiation. The novelty is that the middle zone contains, in addition to the doping concentration Nd, donors of density Nz+ which are produced by irradiation at below 300 K and which are intermittently provided at less than 300 K after forward current application, the density maximum being sufficiently high to produce avalanche breakdown at -40 deg C by triangular field progress and at 75% of the room temperature specified blocking voltage UR and the density minimum being 20% of the maximum value. Also claimed is a method of measuring the carbon content in silicon by exposing a silicon diode structure to thorough irradiation with fast particles of chosen energy and dose so that the number of radiation-induced donors approaches a saturation value, followed by calculating the carbon concentration from this donor density measurement by deep level transient capacitive spectrometry (DLTS) or by means of the voltage of onset of dynamic IMPATT oscillation.

Title: Cooling system for circular saw blades
Inventor: JANSEN-HERFELD ROETTGER DIPL I
IPC: B23D59/02
Filed: 1997-04-10
Abstract: The spray cooling system (11) uses a mixture of water and air which may be sprayed onto the teeth (1) of several saw blades operating in parallel, and also between the blades. The system consists of a large-diameter pipe running parallel to the shaft carrying the saw blades. The pipe has a row of nozzles (14) positioned to spray the water-air mixture onto the blades. A small-diameter pipe inside the large-diameter pipe is filled with water and has side tubes discharging into the jets. The water jets may induce a flow of air from the space inside the large-diameter pipe to form the spray of water droplets in air. Water under pressure (9) may be supplied to the inner pipe and air under pressure (8) to the outer pipe.

Title: Anti-lock brake control device for motor vehicles
Inventor: NAITO YASUO
IPC: B60T8/84
Filed: 1997-11-28
Abstract: The device has a wheel speed detection device for individual wheel speed detection, a brake force adapter for adapting brake pressure in response to the actuation of a brake and an ECU for computing control demands for the adapter based on the wheel speeds when the brakes are actuated to prevent the tendency of the corresponding wheels to lock.

Title: Methods of ensuring safe use of electronic and electro-mechanical apparatus
Inventor: FRIEDRICH HANS-JOSEF
IPC: A41D13/00
Filed: 1997-12-01
Abstract: The safety methods warn the apparatus user to limit their use of the equipment, e.g. someone working at a monitor is warned to take a break after a specific time. The user is warned with a screen symbol, message or by a tone. The type of warning signal/image is pre-selected by the user. If the warnings are continually ignored the appts. is programmed to refuse further service until a break has been taken.  Sensors monitor if the user is taking recommended exercise during the break by means of a sensor mat attached to the system to monitor movement, radio linked exercise appts., distance measuring appts. in an arm band. Pulse sensors are used to monitor low productivity/tiredness. Sensors in chairs are used to monitor the length of time watching television. A form of enclosure is placed over the equipment and secured by a mechanical or computer controlled time lock.  Computers or computer based games can be provided with a facility to limit use.
Patent DE-19757104-A1 (DE)
Title: Backwashing gas filter
Inventor: KWETKUS ANDREAS DR
IPC: B01D46/42
Filed: 1997-12-20
Abstract: Gas flow in the filter is radially outwards so that dirt accumulates on the inside of the bag from where it is removed as the top is closed and the bottom is opened to vacuum. The filter comprises rows of vertical tubular bags that receive raw gas into their upper openings. The bottom of each bag is open and projects into a chamber (8) which is isolated from the outside by a valve (12). Where all bags are to be cleaned simultaneously, in a batch-wise operation, the tops of the bags are closed, the valve is opened so that the chamber (8) is connected via a pipe (9) to a vacuum chamber (10) which is evacuated by a pump (11). The higher pressure of the clean gas in compartment (4) then causes a reverse flow and therefore cleaning. In a continuous operation each row of bags has its own pipe (9), and associated valve.
