Patent DE-3901197-A1 (DE)
Title: Water separator for fire-damp lines
Inventor: GOETSCH ERWIN
IPC: E21F7/00
Filed: 1989-01-17
Abstract: Gas/water separator for fire-damp and natural-gas lines. In order to separate gas, accumulating in mine operation underground, from entrained water before the gas/water mixture reaches the gas line and causes corrosion damage here, a separating pump is used. The frequently occurring failure of the water separators in use up to now, which can primarily be attributed to disintegration through corrosive salt water, is prevented by the novel separating pump by the separation of gas and water being effected before the gas to be drawn off reaches the gas line provided for this.

Title: Ducted open-circuit solar collector installation
Inventor: MEUCHT BERNHARD
IPC: F24D19/10
Filed: 1989-02-04
Abstract: This installation is used to obtain domestic hot water with the aid of solar energy. It is characterised in that the solar collector is supplied directly with cold water and the hot water is retained in an unpressurised storage tank. When the preset hot-water temperature in the collector is reached, a solenoid valve opens, controlled via a thermostat, and supplies the collector with cold water, and the heated water is conveyed into the storage tank. By way of the filling-level monitoring device of the storage tank, when the storage tank is full the solenoid valve is switched off and when it is empty this is indicated or the conventional installation for obtaining hot water is set in operation. <IMAGE>

Patent DE-3931117-A1 (DE)
Title: Recovering heat and dust from hot waste gases - by thermodynamic action on liq. layer
Inventor: MATEI NICOLAU
IPC: F28D21/00
Filed: 1989-09-18
Abstract: In recovering both heat and suspended particles from high-temp. fluid or heat only from a suspension-free fluid, esp. from hot waste gases, heat is transferred from gas to water during dry cooling of the gas. The system utilises the intensive heat exchange at the surface of turbionar-quasi compressible thermal layers. After partial cooling, incoming dusty gas is fed by a central distributor into a series of tubular units for sepg. dust, with the purged gas then further cooled by sec. heaters inside a boiler. A tert. heater with descending inclined tubes then transfers retained particles into a bunker, while corresp. rising tubes collect hot gases, and further descending tubes distribute cooled gases from the boiler into a fixed collector. ADVANTAGE - No compressed air is needed, and clogging by dust is largely avoided.

Title: Locking rolling mill rings on to shaft - shaft has assembly including inner and outer rings, flange, radially flat pressure faces and coaxial tie rods distributed around edge
Inventor: KREISEL PAUL
IPC: B21B27/02
Filed: 1990-02-09
Abstract: A locking system for rings on a shaft, and particularly for the rings of rolling mills on a through shaft, slides the rings axially on to the shaft and holds them there with screws by applying pressure between the flat end faces of flanges so that the rings lock on to the shaft; in the system at least one flange can move axially relative to the shaft; a number of screws are distributed uniformly round the circumference of the flange to act as tie rods and parallel to the shaft on to flanges between the rings. The axially moved flange consists of (a) an inner ring acting together with the tie rod screws and of (b) an outer ring round it; a locking device supported against the shaft can be coupled or uncoupled from the flange with the inner ring and at the side remote from the tie rod screws; by this means the outer ring can be moved relative to the inner ring by mutually engaging threads and as a clamping nut against the roller ring. ADVANTAGE - The design of the system ensures that the rings are locked securely against turning on the shaft under all operating conditions (particularly the roller rings on the through shaft) and that this obtains without any undesirable reactions on the tie rod screws or any problems in dismantling the assembly.

Title: Determination of image edge structure - uses comparison process to set transmission process
Inventor: SUESSMEIER GEORG DIPL ING
IPC: G06T5/00
Filed: 1990-02-12
Abstract: An image processing system has the image sampled and represented in part image blocks. The data transmission capacity, e.g. 64 kbit/s determines the quantisation characteristic and a compromise, is adopted between data rate and error probability. Coupled to the process is comparison to determine if the image is set from an edge and is based upon a threshold value. The threshold value is dependent upon the average luminance value of the image point. The quantisation characteristic is then controlled to achieve the required compromise. ADVANTAGE - Increased data rate without loss of quality.

Title: Piston for fuel injection pump - has increased radial clearance over end region to eliminate cavitation
Inventor: SCHACHT HANS-JUERGEN
IPC: F02M59/44
Filed: 1990-03-06
Abstract: The fuel injection pump has a piston (3) which operates in a cylinder with a radial clearance (5) over the main part of its length. The upper end of the piston has a helical groove with an edge (7) which controls the instant at which the inlet ports (9, 10) are closed.

Patent DE-4014845-A1 (DE)
Inventor: SPRINGER WOLFGANG DIPL BIOL DR
IPC: C12Q1/689
Filed: 1990-05-09
Abstract: The detection method for the determination of Nitrosomonas strains in waste water and soil makes use of a gene probe which, by reason of its complementary sequences, hybridises only with parts of the genome of Nitrosomonas strains from samples of waste water or soil and does not give a positive hybridisation signal with parts of the genome of other bacteria and entails the hybridised nucleic acid being determined quantitatively with the aid of a known label on the gene probe and thus providing a direct measure of the content of Nitrosomonas strains in the sample of waste water or soil.
