Inventor: RUTZ ANDREAS DR ING
IPC: F26B21/08
Filed: 1992-10-21
Abstract: The object is to remove the water from a pasty material, in particular sewage sludge, which contains solids, water and additives, down to a remaining residual moisture of about 5% by weight at a process gas temperature which is far below the mobilisation temperature of the additives, in addition to remove the moisture from the process gas, avoiding production of condensate in the form of polluted water, and to exclude pollution of the atmosphere with pollutant-containing plant air having a high degree of odour pollution. The solution is a drying process, according to which a process gas stream, enriched with moisture, is conducted within a first process circulation from a dryer to a gas dehumidifier, the process gas is dried by removal of moisture in the gas dehumidifier and the dried process gas is returned to the dryer, and, within a second process circulation, the moisture bound in the gas dehumidifier is removed. <IMAGE>

Title: Method for producing a positively engaging connection between semiconductor components and metallic surface of carrier elements
Inventor: WILDE JUERGEN DR ING
IPC: H01L21/603
Filed: 1993-02-10
Abstract: The subject matter of the invention is a method for producing a positively engaging connection between metallic surfaces of semiconductor elements and carrier elements. Between a semiconductor and a substrate which are each provided with surfaces of materials with relatively high melting points, an intermediate layer consisting of a metal which has a lower melting point than the semiconductor and the metallic substrate is arranged. The semiconductor surface which has a relatively high melting point and the intermediate layer which has a low melting point and the substrate metallization which has a relatively high melting point are placed in contact with one another and heated with a prescribed variation in temperature and contact pressure to or above the melting temperature of the intermediate layer, such that the liquid intermediate layer wets the joint surfaces of the semiconductor and substrate. By diffusion of the disappearing, liquid intermediate layer into the semiconductor metallisation and the substrate metallisation, an inter-metallic phase of material of the intermediate layer and of the connector and the contact to be joined is formed. Finally, by cooling and solidifying during the prescribed variation in temperature and contact pressure, the positively engaging connection is produced between the semiconductor and the substrate. <IMAGE>

Title: Process and apparatus for separating off and recovering abrasives when using water/abrasive blasting
Inventor: LOUIS HARTMUT PROF DR ING
IPC: B04C5/00
Filed: 1993-02-10
Abstract: The solids (abrasive and joint material) settling in the collecting system filled with water are fed with the assistance of additional water jets by a pump to a hydrocyclone and are thereby separated into two part streams which, in addition to water, essentially contain, on the one hand, re-usable solids and, on the other hand, solids requiring disposal. The solid which is to be re-used is, in the case of water/abrasive suspension blasting, taken directly to a re-use. For water/abrasive injector blasts, prior drying should be carried out. The suspension requiring disposal is thickened by means of a hydrocyclone, the solid being classified and taken to disposal, and the water being recycled into the circulation.

Patent DE-4405559-A1 (DE)
Inventor: GERLACH HORST DR ING
IPC: H02M7/162
Filed: 1994-02-16
Abstract: Rectifier substations in which the main thyristor is extinguished by means of an extinguishing and load device are known. To ensure the undisturbed running of railways, the current must be guided into a switching branch when the thyristor in the rectifier of the substation is switched off. An extinguishable switching branch is achieved in that switching currents that flow from the busbar (20) to the line portion outputs (a1, a2) and from the line portion outputs (a1, a2) to the busbar (20) are led through a switching thyristor (12) that may be extinguished by the available extinguishing and loading device. An uncoupling diode (17) allows short extinguishing current paths to be achieved and the main thyristor (2) remains erasable even when all line portion outputs switches (1a, 12) are switched off. This extinguishable switching branch represents an economic design of a rectifier substation with central thyristor switch.
