Title: Environmentally friendly rubbish burning - involves high temp. combustion followed by high temp. afterburning of flue gases and special filtration process.
IPC: F23G5/08
Filed: 1991-09-18
Abstract: The rubbish mass prior to combustion is chopped and made into briquettes (2) in order to ensure an optimal combustion process. Coke (1) is then added to the briquettes in given amts. to help support combustion. Preheated combustion air is added to the material in order to achieve a high temp of approximately 1600 deg  to 1800 deg  C. This causes harmful material which results from conventional rubbish burning, to be burnt into unharmful constituents at this high temp. The flue gases from the rubbish burning are cleaned in a wet filter unit with lime milk. USE/ADVANTAGE - To dispose of rubbish in an environmentally friendly manner.

Patent DE-4134240-A1 (DE)
Inventor: ADLER UWE DIPL ING
IPC: B62D5/00
Filed: 1991-10-16
Abstract: In a motor vehicle equipped with a hybrid drive formed by an internal combustion engine-generator unit (16), steering is actively assisted when taking curves by controlling the individual drive (8, 10) of the outer and inner wheel depending on the steering angle ( delta A) of the steered wheels (4, 6), so that a moment differential is set and the percent real differential speed of rotation of the wheels nears the percent set differential speed of rotation of the wheels. With this differential moment, and as the outer wheel (4) is more strongly driven in the curve than the inner wheel (6), the force that has to be supplied by the steering system (20, 22, 12) in order to adjust the steered wheels is substantially reduced.

Patent DE-4203895-A1 (DE)
IPC: E01B3/34
Filed: 1992-02-11
Abstract: In order to produce prestressed concrete sleepers with immediate tensioning, the tensioning wires (5) are directly drawn from one or several wire rolls (10) and longitudinally introduced in a tensioning frame (8), then anchored at the front end (19) of the tensioning frame (8), viewed in the direction of advance. The wires (5) are tensioned and also anchored by means of a tensioning device (13) arranged out of the tensioning frame (8) and supported against its opposite end (20); only then the wires are cut by means of a cutting device (25). It is thus possible to unite in a single station operations that were until now carried out by several production stations, such as cutting to lengths, introducing and tensioning the wires, thereby dispensing with the labour- and time-intensive handling of wires previously cut to lenghts.

Patent DE-4231392-A1 (DE)
Inventor: BRUGGER HANS DR RER NAT
IPC: H01L21/66
Filed: 1992-09-19
Abstract: A process is disclosed for determining the electronic properties of semiconductor structures, in particular modulation-doped field effect transistors (MODFET). The electric resistance and the Hall coefficient of parallel conducting semiconductor layers of the MODFET are determined. A mobility spectrum is derived from these measurement values and its results are subjected to an error calculation. The load carrier densities and the mobility of parallel conducting layers are determined from the mobility spectrum. The channel carrier density and mobility of series of layers can thus be optimised. In addition, knowing the conductivity of the top layer is important to achieve high breakdown voltages in field effect transistors.

Title: Chopper amplifier controlled solenoid valve operation - has up to 20 percent variation in frequency generated as pseudo-random signal provided by controller
Inventor: BAUER BERNHARD
IPC: G05D16/20
Filed: 1992-09-23
Abstract: An electronic control system for solenoid valves is based on a chopper circuit principle in which a square wave signal of variable pulse is used to sample a second signal. In comparison to prior art systems where the chopper frequency is held constant, the circuit uses a frequency with a 20% variation over the average total frequency range. The variation in frequency is produced by using a pseudo-random signal generation implemented in software. The non-uniformity of the frequency improves the signal-to-noise ratio. USE/ADVANTAGE - For hydraulic or pneumatic valve control.
