Abstract: A multicomponent, in situ foaming system is described for the preparation of interpenetrating polymeric networks of foamed polyurethane and at least one further polymer for in situ construction purposes with a polyisocyanate component (A) and a polyol component (B) for forming the polyurethane, and further components (C) and (D) for forming the further polymer. Components (A) and (B) are present in a reaction-inhibiting, separate form. The components (A), (B), (C) and (D) are present in the form of one or two mixtures, in which the components (A), (B), (C) and/or (D) are contained separately in a micro-encapsulated form in order to inhibit reaction so that the components polymerized with formation of the interpenetrating polymeric network only when the components are brought into contact with one another after destruction or opening of the microcapsules.

Abstract: The present invention relates to a method for the detection of acute respiratory tract infection (ARI) comprising the simultaneous amplification of several target nucleotide sequences present in a biological sample by means of a primer mixture comprising at least one primer set from each one of the following gene regions: the F1 subunit of the fusion glycoprotein gene for RSV, the hemagglutininneuraminidase gene for PIV-1, the 5? noncoding region of the PIV-3 fusion protein gene, 16 S rRNA sequence for M. pneumoniae, 16 S rRNA sequence for C. pneumoniae, the 5? noncoding region for enterovirus, the non-structural protein gene from influenza A, the non-structural protein gene from influenza B, and the hexon gene for adenoviruses. This multiplex RT-PCR method is particularly preferred because it allows to determine the presence of the following microorganisms which infect the respiratory tract of mainly children in one amplification step: RSV, parainfluenza virus, M. pneumoniae, C.

Abstract: A sifting machine comprises a stationary sifting basket, a rotor rotating within the sifting basket and a worm conveyor feeding into an end of the sifting basket for dosing and introducing the material to be sifted. The rotor and the worm conveyor are driven for rotation, wherein, in order to achieve an optimal rate of revolution adjusted to the desired mode of operation for both the worm conveyor and the rotor, each has its own drive device. In order to facilitate removal, the unit comprising the rotor, the sifting basket and the associated drive mechanism can be axially removed from the sifting machine housing and subsequently pivoted-out in a sideward direction via a pivot bearing.

Abstract: The invention concerns a binding matrix containing a carrier material and a solid phase reactant which is adsorbed to this via anchor groups that is capable of binding to at least one free reaction partner wherein the solid phase reactant forms a dilute and essentially laterally homogeneous binding layer on the surface of the carrier material. In addition a method for the determination of an analyte in a sample solution is claimed in which a solid phase reactant is used which is a component of a binding matrix according to the present invention. In this process the specific binding reaction is preferably determined by optical reflection techniques.

Abstract: A circuit arrangement (1000, 2000), preferably for a coupling network component of a network node in a packet-switching data network, is disclosed which has a wide parallelization of the data packet signal by means of shift registers (60), so that it is possible to operate internally with a greatly reduced operating speed. In particular, an arrangement of the components on a single semiconductor wafer (3000, 4000) permits an especially wide bus (20), which can be constructed extremely advantageously with a surface-optimized floor plan (3000, 4000).

Abstract: A blowout system for ejection and discharge tubes of submarines is provided which permits an ejection of weapons from a torpedo tube, said weapons not having an own propulsion, and which prevents the intrusion of water after the blowout operation is terminated. The system is subsequently installable as a compact unit and has an outlet opening which is closed by a check valve. The outlet opening is continued by a buffer tube, a blowout valve arranged between a compressed-gas container and said buffer tube being provided for supplying said compressed gas.

Abstract: An x-radiator has a housing in which an x-ray tube is disposed surrounded by an electrically insulating coolant and having a circulation system for the coolant. The housing is substantially filled with the coolant, and a heat exchanger is disposed outside of the housing through which the coolant is pumped. *) The direction of flow of the coolant is automatically reversible dependent on the three-dimensional position of the x-radiator. *) For aiding in dissipating heat from said coolant a cooling fluid is circulated through the heat exchanger isolated from the coolant.

Abstract: An expelling mechanism adapted for use with discharge tubes and drain tubes of submarines for ejecting a weapon by compressed air includes a chamber formed with an outlet opening, and adapted to substantially communicate selectively with a storage container holding compressed gas, a discharge valve which may be moved towards the opening in a closing direction, and away therefrom in an opening direction at a selectable opening velocity, and a hydraulic control device for controlling the movement of the discharge valve. The hydraulic control device includes a cylinder adapted to be filled with hydraulic fluid, a piston reciprocally movable along a stroke within the cylinder, and partitioning the cylinder into two cylinder chambers, an overflow channel establishing communication between the cylinder chambers, and a connecting device connecting the discharge valve with the hydraulic control device.

Abstract: A device for determining the timely delivery of compressed gas from compressed-gas containers for ejection and discharge tubes of submarines in which the compressed gas is suppliable via a system-controlled blowout valve comprising a compressed-gas container having a pressure pick-off with a pressure gauge and a converter for producing an electrical signal representing the actual pressure value. Upper and lower desired pressure values in the form of electrical signals are adjustable on transmitters electrically connected to separate comparator stages to which the electrical signal of the actual pressure value and, in each case, one of the signals of the adjusted predetermined values are supplied and by which a timing member having a running time indicator is controlled. The timing member is started when the pressure in the compressed-gas container falls below the adjusted upper pressure value and is stopped when the pressure in the compressed-gas container reaches the adjusted lower pressure value.
