Title: Appts. to generate large phase boundary area dispersion of solid and gases - for prodn. e.g. of polyurethane foam, foamed glass, metal foams and ceramic foams
Inventor: WAGNER KAI DIPL ING
IPC: B01F5/10
Filed: 1992-11-06
Abstract: The appts. generates a dispersion of materials with a large phase boundary area including solid materials and a fluid (F) or gaseous phase (G). The phases have different specific weights resulting from the operating conditions in the separation assembly and that each phase can dissolve in the other under the right conditions. The appts. consists of a dispersion unit (R), a separation unit (S), tubes inking the flow paths (D1, G2, F2), units which are required to bring about the necessary fall in pressure of the materials employed, together with inlet and outlet tubes (G1, F1, N, D2). USE/ADVANTAGE - The process may be used in the manufacture of polyurethane foam, foamed glass, metal foams, ceramic foams, the acceleration of bio reactions and stripping extractions. The appts. generates a fine-celled dispersion containing a high proportion of the dispersed phase.

Title: Automatic image quality compensation in video system - separating luminance signal from composite video signal and determining luminance signal level
Inventor: MIN BYOUNG OUK
IPC: H04N5/57
Filed: 1992-11-30
Abstract: The image quality compensation method involves separating a luminance signal from a composite video signal and determining its level to adjust brightness of an image content. From the separated luminance signal horizontal HF components are determined for the image contrast. From the composite video signal a correlation signal is determined for the image content contrast determination. The envelope peak value of the video signal is determined, the luminance signal level, the horizontal HF components, the vertical correlation, and the envelope signal with a d.c. level are amplified. All these values are scanned and the scanned signals are converted into digital data. The processing of the signal values controls the brightness and contrast of the image content. USE/ADVANTAGE - For video tape recorders, colour TV receiver etc.. Improved control of image brightness and contrast.

The time duration of the re-wiping operation of the screen wiper motor (3) is determinable, depending on the output signal of the counter (13). ADVANTAGE - Control circuit is designed so that re-wiping is better matched to need as result of applied amount of washing medium.

Title: Determining cutting path data for NC milling machines - deriving reference path data for largest size cutter followed by modification for smaller size cutter when remnant material is identified
Inventor: ITAMOTO TAKESHI
IPC: G05B19/4093
Filed: 1993-07-14
Abstract: A multi-axis NC milling machine produces complex 3D profiles by moving a bull nosed cutter along a defined path. The profile data is generated by a computer aided design, CAD, package and initially the path is established for a large diameter cutting tool. Based purely upon this size of cutter, the profile actually produced will differ from the ideal. Remnant area (D) will be left at changes in section. Such areas are identified and a second trajectory is established when a smaller diameter tool is used. The procedure can be repeated if necessary for a third smaller tool. ADVANTAGE - Simplifies generation of cutting path data, reducing working time and man hours.

Title: Method for determining urine in reusable bottles and containers
Inventor: HEIDRICH CHRISTINE
IPC: B08B9/46
Filed: 1993-08-17
Abstract: The invention relates to a method for determining urine on the basis of the index component NH3 which is converted into NO in a combustion, UV or redox catalyst and then fed into an ozone stream of constant concentration. The gas-phase titration which then takes place leads to a decrease in the ozone concentration, which is measured using UV absorption at 253 nm. Sensitivity and detection limits show the advantage over known detection methods using chemoluminescence reactions. The transition from the IR to the UV measuring technique exhibits a considerable economic advantage in addition to the advantage in connection with measurement procedures.

Patent DE-4400974-A1 (DE)
IPC: B21B1/16
Filed: 1994-01-14
Abstract: In a reinforcing steel that has indentations (4) rolled into a steel rod of approximately circular cross section, the indentations are formed as the reinforcing steel is unwound through circular arcs of different radii set axially symmetrical relative to the indentation. The indentations are rolled into the surface of the rod at a constant depth and have steep flanks. This ensures sufficient bonding despite a lower deformation effort, providing for better ductility parameters. Furthermore, the coiled reinforcing steel has better directivity and improved suitability for welding in the manufacture of welded wire mesh. A process for manufacturing such a reinforcing steel comprises at least two deformation steps.

Title: Throttling skirt for striking-wheel mills
IPC: B02C13/288
Filed: 1994-05-10
Abstract: The present invention relates to a throttling skirt for striking-wheel mills which is built into the free connection surface between grinding chamber door and grinding chamber. In known throttling skirts, operation-threatening distortions, weld-seam tears and in borderline cases tearing off and destruction of the throttling skirt arise as a result of the thermal loading. The aim of the invention is therefore to provide a construction and means of fixing of the throttling skirt which exclude the disadvantages mentioned above. According to the invention, this aim is achieved by the throttling skirt consisting of a number of skirt strips (1) which are suspended freely movably at a distance from one another on the grinding chamber door (4) or on the grinding chamber. <IMAGE>

Abstract: For evaluating the output signal in the form of a binary current signal (IS) from an active sensor (1), a circuit is proposed in which a proportional current is derived from the sensor current (IS) with the aid of a current balancing circuit (2, 2'), and the current (I1) resulting from current balancing is drawn off from a stabilised voltage source (UK) via an ohmic resistor (R1), thereby generating a binary voltage signal (V1) which is applied to a flipflop (3) comparing the voltage signal (V1) with a reference voltage (UBez) composed of a reference voltage (URef) and a hysteresis voltage. The switching threshold of the flipflop (3) is varied or adjusted in accordance with the actual sensor current (IS), leakage currents, etc.
Patent DE-4442154-A1 (DE)
Inventor: JUEHE HANS-HELMUT DR
IPC: B65H19/10
Filed: 1994-11-26
Abstract: The invention concerns a method of detecting faults produced immediately on or over the central spool when a continuous strip of paper is wound on the spool. The method calls for the temperature at the end of the spool to be measured continuously by a non-contact method during the time the roll has between 100 % and 60 % of its fully wound weight. When a temperature difference of  >/=  0.5  DEG C is detected, within a zone in the central region of the roll, between measurement points or areas in the zone and in cooler adjacent areas, the radial distance between this zone and the surface of the central spool is determined and stored for use in triggering a signal which initiates the replacement of the roll when this distance is reached.
