Patent DE-19633481-A1 (DE)
Title: Exhaust control for IC engine
Inventor: WUNDERLICH ARNO DIPL ING
IPC: F02D41/14
Filed: 1996-08-20
Abstract: The IC engine has a lambda control with a sensor in the exhaust dust linked to the engine management system. To check the effectiveness of the control a programmed change is made in the engine control and the response of the lambda control is monitored. No special system is required; the check is made using an existing engine control system. For instance, a programmed change is made in the fuel/air mixture and the response is monitored. The change can be in either direction; lean or rich. Another programmed change can be in the air flow added to the exhaust duct. The programmed change can be initiated by a test switch inside the engine compartment, or it can be part of the test programme in the engine diagnosis programme.

Title: High-power internal combustion (IC) engine ignition device
Inventor: PEIER DIRK PROF ING
IPC: F02P23/04
Filed: 1996-09-21
Abstract: The ignition system for fast running IC engines has the electric energy to ignite the fuel-air mixture provided by an RF generator (6). An electrode (7) in the cylinder head injects the microwave power into the cylinder to initiate an even burn. The cylinder head, cylinder and piston provide a metal enclosure for the microwave power. The electrode is shaped with lateral profiles surrounding a central electrode shaft. This provides a controlled pattern of microwaves during ignition, and with a shaped wave front to initiate the ignition. The microwave field pattern around the electrode enhances the burn and the ignition is controlled w.r.t. the position of the piston in the compression stroke.

Title: Drying process for wide range of wet industrial wastes or biosludges
IPC: F26B23/02
Filed: 1996-09-26
Abstract: New process combines impact dewatering with simultaneous drying. Used to dry moist materials using mechanical impact de-watering, especially industrial wet products, by-products or wastes.The process is suitable for very wet materials. If transported in this state, their volume and weight would incur high transport-, further processing- and disposal costs. A product example is dried granulated sludge for application with mineral fertiliser granules. A range of other industrial disposal problems are discussed in the patent. The process design reduces the degree of de-watering required to prepare the material. Efficient, direct thermal contact is applied in the drying process, which is designed for optimal heat transfer by various mechanisms in each stage. The fluidised bed combustor can produce heat from e.g. dried sludge at up to 24MJ/kg, comparable to black or brown coal dust. It is claimed that up to 70%

Patent DE-19706012-A1 (DE)
Inventor: KLOSE FRANK PROF DIPL PHYS DR
IPC: G01R33/09
Filed: 1997-02-09
Abstract: Magnetic sensors having a ferromagnetic layer structure wherein said layers are interchangeably coupled by means of non-magnetic metal intermediate layers, are used in modern storage technology to read magnetically stored information. If reading is to be precise, accuracy in determining modifiable magnetic resistance should be very high. Accuracy in known magnetic sensors is influenced by intermediate layers of a given constant thickness. Optimization is no longer possible after production. Furthermore, the use of known magnetic sensor is restricted to field sensing. The magnetic resistance of the inventive magnetic sensor can be continuously and reversibly modified and optimized by charging hydrogen on the intermediate layers which consist of Nb exhibiting an affinity with hydrogen or a Cr alloy exhibiting an affinity with hydrogen and having a layer thickness in the core area ranging from 1.3 nm to 1.6 nm. THe inventive sensor can used as a magnetic sensor, specially in comprehensive areas of magnetically-stored information processing, as well as a hydrogen sensor, and can be used to detect totally differing physical measurement variables.
