Title: Automatic balancing haemofiltration appts. - with capacitive measurement of filtrate and automatic proportional replacement
Inventor: HOH HANS ULRICH
IPC: A61M1/34
Filed: 1979-01-17
Abstract: The appts. is designed for adaptation to a conventional haemodialysis appts. using its blood circulation monitoring system (air detector, etc.), so that haemofiltration can be balanced automatically. This makes it possible to carry out at one point both haemodialysis and balanced haemofiltration. Capacitive measuring of quantities for haemofiltration is applied, and the balancing is carried out without weighing. The appts. is small, light and cheap and dispenses with the weighing system. Direct continuous measurements of the amt. of filtrate takes place and the process eliminates the expense of weighing methods which due to the accuracy and security required are subject to upsets.

Title: Domestic radiator water pump - automatically refills water vessels from mains to counteract evaporation loss
Inventor: HOFFMANN GERHARD
IPC: F24D19/00
Filed: 1979-04-02
Abstract: The water pump is for use with domestic heating radiators. It is designed for connection to the electric and water mains. The pump mechanism is automatically controled by floats or diaphragms in the individual radiator water vessels. This system serves to top them up as soon as the water level falls, due to evaporation, below a set level. Thus the rooms heated also have the relative humidity of the atmos. maintained at the correct level.

Title: Spaltprodukt-filter fuer heisses reaktorkuehlgas
Inventor: FOERSTER SIEGFRIED DR
IPC: B01D46/40
Filed: 1979-09-14
Abstract: Die Erfindung betrifft einen Spaltprodukt-Filter fuer heisses Reaktorkuehlgas, insbesondere Helium, mit einem gasdicht ummantelten Hohlraum, in dem ein Filtermaterial vorgesehen ist, welches die Teilchen durch Wechselwirkung mit seiner Oberflaeche zurueckzuhalten vermag, vom Gas zu durchflutende, in geordneten Geometrien vorliegende Kanaele aufweist und aufgrund seiner Anordnung im Hohlraum vom Gas in Laengsrichtung durchstroembar und in Laengs-oder Querrichtung umstroembar ist. Die Neuigkeit besteht darin, dass als Filtermaterial ein Wellblechwickel verwendet wird. Die Erfindung ermoeglicht es, die im Reaktorkuehlgas befindlichen Spaltprodukte soweit zu entfernen, dass hinter dem Filter nur mehr eine so geringe Radioaktivitaet im Kuehlgas vorhanden ist, die auch nach einer laengeren Reaktor-Betriebszeit eine nahezu unbeschraenkte Zugaenglichkeit zu den Kreislaufkomponenten zulaesst. Ein solcher Filter kann fuer alle Hochtemperaturreaktor-Anwendungsfaelle brauchbar sein.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        ...U.S.W

Abstract: The hourglass-shaped blood bags known to date have a disadvantage in that the production costs are relatively high and the stability is relatively low. The flexible, bag-like blood container having a welded field (2) located within its middle third has a slot (3). This container is cheaper to produce and more stable, and it offers all the advantages of the hourglass-shaped container, i.e. it permits preservation and transfusion of blood and blood components and temporary or permanent separation of plasma and red blood cells. Because it is possible to isolate the buffy coat (B) the container furthermore permits buffy coat-free transfusion of blood or blood components. <IMAGE>

Title: Installation of wiring and fittings in pre-fabricated walls - with fittings flush for transport and finally positioned after building erection
Inventor: SPELSBERG ECKHARD DIPL ING
IPC: H02G3/12
Filed: 1980-01-17
Abstract: The installation method is applicable to dividing walls or partitions made in cavity form. The necessary holes (40) are cut in one face of the wall (11), for example made of plasterboard, and the appliance boxes (10) pushed into position. Spring clips (17) on the boxes act as barbs to prevent the box falling out during transport. The necessary wiring is run, the applicance, typically a switch or socket outlet, connected and pushed temporarily into the box so that it does not protrude above the wall surface. The rear part of the wall is then assembled. After transport and erection the appliance is pulled out of the box and a carrier ring fitted. This typically locates on the appliance at two diametrically opposite points. The carrier ring extends into the box and rests also against the outer surface of the wall. When screwed together with the box a firm location of the appliance, box and ring is achieved. A suitable bezel or faceplate can then be fitted.

Title: Switch for control of IC engine fuel mixt. - has timer relay in conductor line between control unit and fuel injector timing valve
Inventor: BAEHR WULF-JUERGEN ING GRAD
IPC: F02D41/14
Filed: 1980-04-23
Abstract: The control switching device uses an oxygen measuring sensor in the engine exhaust manifold. The sensor transmits an electric voltage to the control unit of the fuel injection system in dependence on the composition of the exhaust gas. The injection system comprises an electrically driven fuel pump with an electrically controlled timing valve. The control unit derives an electric signal on the failure of the oxygen measuring centre. In the electric line (4) between the control unit (3) and the timing valve (1) is incorporated a timing relay (5), supplied with voltage from the control unit on the failure of the oxygen measuring sensor (2). Then after a preset time period the relay interrupts the line between the control unit and the timing valve, the relay being reclosed on operation of the oxygen measuring sensor.

Title: Automatic identification of handwritten tert. - has matrix of detectors using comparison with stored data to identify alpha numeric character
Inventor: RENNINGS MANFRED
IPC: G06K9/00
Filed: 1980-08-01
Abstract: The digital processor is designed to enable handwritten alphanumeric characters to be automatically read and identified. The system is intended to be independent of the particular hand-writing style. The particular character is reproduced on a matrix field using a laser or magnetic probe. A matrix of detector cells respond to produce a specific pattern of '1' and '0' signals. The signal pattern is buffer stored and also results in a memory being accessed. The two sets of data are compared and an identification made that is used to provide print-out and storage in a text memory.
