Title: Underground high-temp. rotary refuse incinerator - separately disposed of different types of combustion prod.
Inventor: MANIURA REINHOLD
IPC: F23G5/00
Filed: 1990-01-26
Abstract: An incinerator for dangerous or difficult refuse including poisonous components, is housed deep underground and consists of an inclined tube boiler with three layers. Combustion of refuse is aided by tangential injection at separation positions of fine coke, gas and O2, to ensure combustion temp. about 1600 deg.C.. While materials such as Ni, Cu, As are reduced to harmless atoms, mineral components based e.g. on Ca, Si, Cr, Mn are formed into granular ash. Many metals (Hg, Zn, Sn, Pb, Cd) can be recovered, or condensed with the ash for formation into pressure-resistant impermeable blocks to be raised to the surface and transported for safe tipping. Waste water is used for distinct heating, while and electrolyses produces pure H2. ADVANTAGE - No environmentally damaging materials are discharged into the atmos..

Title: Programmable-memory of analogue-to-digital converters - using parameter-based routines to manipulate multiple-channel conversion data in process control applications
Inventor: MEHLGARTEN UWE DIPL ING
IPC: G05B19/05
Filed: 1990-04-02
Abstract: The process controller comprises several sensing devices,  containing one or more Analogue to Digital Converters (ADC), and a programmable-memory controller connected to the address bus of a central processor.

Patent DE-4021368-A1 (DE)
Inventor: ARAKAWA SHINICHIRO
IPC: F04D29/42
Filed: 1990-07-05
Abstract: A centrifugal pump casing of a centrifugal pump, comprising a casing shell (1) accommodating a rotary impeller (8) therein and having as a basic circle an inner peripheral circle having a diameter greater than the diameter of the outer peripheral circle of the impeller (8) is disclosed. A bulged portion (1a) bulged radially outwardly is integrally formed on the outer peripheral wall of the casing shell (1), the bulged portion (1a) extends from a starting point (b) remote from the winding starting point (a) of the casing shell (1) in a circumferential direction to an end point (c) while gradually increasing in height in the direction from the starting point (b) to the end point (c). A pipe-like discharge nozzle (18) is connected with the casing shell (1) so that it extends between the end point (c) where the bulged portion (1a) is highest and the winding starting point (a) where no bulged portion is formed. In this arrangement, since the bulge height above the basic circle is not so great even at the end point where a maximum height is reached, the bulged portion (1a) can be formed through only one pressing process without the need for an annealing process. Further, since the difference in height between the end point where the bulged portion (1a) is highest and the winding starting point (a) where no bulged portion is formed is not so great, the wall portion of the casing shell (1) at the winding starting point (a) can serve as a guide, and accordingly, a guide for discharge water which is required in the prior art may be eliminated.

Title: Impregnating continuous substrate - by dipping in a bath, coiling on a perforated roll and subjecting to a low surrounding pressure to remove air, etc.
Inventor: FISCHER DIETER
IPC: B05D1/18
Filed: 1990-10-04
Abstract: Impregnation consists of feeding the substrate (3) through an impregnation bath (15) in a chamber which is under atmospheric pressure. The substrate coated with the bath material is then coiled onto a roll (25) which has perforations enabling access to its central tubular section. The chamber is then subjected to a high pressure or vacuum. The coil-up roll (113) may have solvent passed through its central area via (129) as a low pressure is maintained around the coil or solvent passed around its outside as the low pressure is achieved in its central area. The latter is achieved by dipping the roll (113) in the bath (15). USE/ADVANTAGE - Used esp. for lacquer coating materials. The low pressure vacuum in the chamber enables the removal of air and/or solvent particles from the substrate ensuring good quality coating. (1/1)

Title: Setting up longitudinal acceleration sensor for motor vehicle brake balancing - measuring parameters with vehicle facing up and down a slope and deriving null point correction from both values
Inventor: THUERSAM JUERGEN
IPC: G01P21/00
Filed: 1991-03-13
Abstract: The method of compensating a longitudinal acceleration sensor for motor vehicles involves storing a rfirst measurement parameter measured on a vehicle (1) support surface (2) with an inclination angle (2) in an electronic controller (5). With the vehicle facing the opposite way on the same support surface at the same inclination angle, a second measurement value is taken and can also be stored.
