Title: Embroidery stitch data
Inventor: KYUNO MITSUYASU
IPC: D05B19/08
Filed: 1995-02-23
Abstract: To process embroidery data, an image scanner (12) scans the original pattern to register at least one embroidery zone defined by an outer line so that embroidery data can be generated for the area within the defining outer line. A system (7, 11, 13) takes the image data to form stitches round the outer line. A unit (13) uses the image data to give the stitch data within the outer line. The stitch data contain the information for stitching the outer line and for filling the ares within the line. Also claimed is an operation where the specifies for an initial sewing are contained in the outer line or area stitching data.

Title: Heat pump with freeze-protection
Inventor: GOLUEKE WILFRIED
IPC: F25B47/00
Filed: 1995-05-23
Abstract: A heat pump has an evaporator, a compressor, a liquefier and an expansion valve in a coolant circuit, whereby the evaporator extracts energy from the water fed to it and has a freezing protection circuit to switch off the compressor. A sensor (8) in this circuit measures the coolant temperature at the outlet of the evaporator and if this is below a lower limit, switches the compressor off.  This limit is between +3 deg C and -3 degC. The sensor is fastened to the suction steam pipe of the evaporator. The sensor has a filling of a low boiling point expanding fluid like alcohol.

Title: General purpose dowel unit
IPC: F16B13/06
Filed: 1995-06-17
Abstract: An expander (6) in the inward end of the dowel has a conical expanding sector (5) within a sleeve (7) which has to be moved axially to spread out in diameter as it slides onto the expanding sector (6). An actuator produces the relative movement of sleeve and expander and an interlayer between expander and sleeve consists of smooth metal foil or plastics film fixed in between the expander and sleeve.  The axial length of the interlayer (11) equals that of the expanding part of the sleeve (7). The interlayer can be parted in band form from a strip and is wrapped round the expander so the band ends overlap. The foil should be of different material from expander and/or sleeve, the expander preferably fitted on or formed by the inner end of the dowel shaft. Once the film or foil has been wrapped round the expander, a shaft-fitted nut is run fast onto the wall to drive the sleeve axially forwards onto the expander via the interposed film or foil etc.
Patent DE-19522674-A1 (DE)
Inventor: LUH JOACHIM DR ING DR
IPC: F16H61/662
Filed: 1995-06-22
Abstract: The invention concerns a hydraulic control unit for changing the hydraulic-fluid pressure to modify the locking force in the mitre-wheel axial-adjustment unit in a continuously variable wrap-around transmission (10). A pump (20) in an open hydraulic circuit supplies the piston space (17) in the secondary axial-adjustment unit with hydraulic fluid, and the hydraulic-fluid pressure in the secondary piston space (17) is controlled by individual pressure-limiting valves, at least one (50) of which is electrically actuated, in dependence on a pressure-sensor signal, to control a proportioning pressure-relief valve (30) designed to limit the secondary-fluid pressure. Current is supplied to the actuator (51) of the corresponding valve (50) by a control device (95) which determines by means of the pressure sensor (90) the fluid pressure in the control line (34) leading to the proportioning pressure-relief valve (30). The control device (95) includes a multiplier unit whose multiplier represents the ratio of the area on the control-fluid side and the area on the secondary-fluid side of the contact surfaces of the proportioning pressure-relief valve slide. This enables a pressure sensor (90) to be used which only needs to be designed for a low control-fluid pressure.

Title: Adaptive test method for determining the freedom from disturbance of cyclically operating devices - employing reinforcement algorithm to determine from statistics of test pulses applied and reaction of test object for adaptive concentration of pulses in time phases with highest probability of disturbance
Inventor: WENDSCHE STEFFEN DIPL ING
IPC: G01R31/28
Filed: 1995-06-24
Abstract: The method employs a reinforcement algorithm. A test control device stores statistics of the test pulse applied in each time phase and the reaction of the test object (PO) to the stresses imposed. These statistics are used for the adaptive concentration to test pulses applied in time phases in which are to be expected the highest probability of disturbance. The statistics are initialised by means of a priori knowledge and during the freedom from disturbance test actualised after each test pulse. Before initiation of the next test pulse, the statistics are evaluated to determine in which time phases statistically the highest probability of disturbances is to be expected and for those time phases a highest probability is to be selected for the stress with the next text pulse.

Title: Culturing eucaryotic cells in medium containing serum or serum substitute
Inventor: FALKENBERG FRANK W PROF DR
IPC: C12N5/00
Filed: 1995-11-07
Abstract: Cultivation of eucaryotic cells uses a culture medium containing serum or high molecular serum substitutes, with fission products from proteins. The cells are cultured in a production chamber separated by a semi-permeable membrane from a supply medium. The serum or the high molecular serum substitutes are added to the culture medium in the production chamber and the fission products are added to the supply medium. The pore size of the membrane is such that the cells, cell products and serum protein of high molecular substituents are retained in the production chamber and the protein fission products, added to the supply medium, can pass through.

Patent DE-19607862-A1 (DE)
IPC: F01N3/28
Filed: 1996-03-01
Abstract: Thermal catalysts, particularly catalysts coated with precious metals, are used to reduce the concentration of CO, HC and NOx in exhaust gases from internal-combustion engines. While catalysts coated with precious metals exhibit catalytic activity from about 140 DEG C, to ensure very low emission levels thermal catalysts need to be heated during cold starting so that the pollutants produced during the cold start react. The invention calls for a catalyst with a photovoltaic semiconductor illuminated with UV light to be used. Suitable for use as the photocatalytic material is e.g. titanium dioxide. This enables pollutant levels to be reduced, even immediately after the engine has been started and even at relatively low ambient temperatures. The invention is suitable for use with diesel engines and lean-mixture spark-ignition engines.

Inventor: GLOSS RAINER
IPC: F15B11/02
Filed: 1996-07-30
Abstract: In an advance-mechanism hydraulic system having a differential thrustor by which an advance mechanism can be adjusted, a directional control valve that controls the supply of the hydraulic fluid to the differential thrustor is positioned between the differential thrustor and a tank-supplied pressure source. In order to limit the force acting on the advance mechanism, a valve is provided that connects the piston-side pressure chamber of the differential thrustor with the tank if the pressure in the piston-side pressure chamber of the differential thrustor exceeds the pressure in the piston-rod-side pressure chamber of the differential thrustor, multiplied by a weighting factor, by a specifiable amount. The weighting factor is equal to the quotient of the piston surface in the piston-rod-side pressure chamber and the piston surface in the piston-side pressure chamber. The advance-mechanism hydraulic system is particularly suitable for use in woodworking machine tools, in which an advance mechanism presses a motor-driven tool, such as a cutter disk, a milling head, or a saw blade, against a workpiece. The use of hydraulic components provides a set-up that is also suitable for rough working conditions.
