摘要:
In an antenna radar system including a short-range antenna path and a long-range antenna path that is situated separately from the short-range antenna path, a push-pull mixer is situated in the short-range antenna path. Using the push-pull mixer, a heterodyne frequency conversion or mixing of the signals to be processed is able to be carried out in the short-range antenna path.

Embodiments relate to a computer for transmitting data in a network. The computer includes at least one data transmission port configured to be connected to at least one storage device via a plurality of paths of a network. The computer further includes a processor configured to detect recurring intermittent errors in one or more paths of the plurality of paths and to disable access to the one or more paths based on detecting the recurring intermittent errors.

The invention relates to a system for injecting a liquid into a body, comprising an implantable chamber disposed under the skin and an injection device including: a base bearing an injection needle having a free end that is intended to be inserted into the chamber; an injection conduit connected to the needle; means for extracting the needle; means that can be actuated to generate excess pressure in the injection conduit; synchronization means between the extraction means and the generation means for actuating the generation means during a needle extraction phase. The synchronization means can essentially only actuate the generation means when the free end of the needle is located in the chamber during the needle extraction phase.

The invention relates to a dispensing module for two liquid products, comprising: a first chamber (20) having a first wall, said first chamber having a first opening; a first piston (61) which can be displaced whilst resting on the wall of the first chamber; a second piston (64) which can be displaced whilst resting on a wall of the second chamber, and coupling means (62) for coupling both pistons whilst the product is being dispensed are provided. According to the invention, in order to prevent functional dysfunctions in the event of a distortion of the shape of container and to freely select the shape of the container, said dispensing module comprises a second chamber, the wall of which can be displaced whilst resting on the second piston, said second chamber comprising a second opening. This is achieved by virtue of the fact that the distortion of the container no longer leads to functional dysfunctions of the dispensing module. Also, the outer shape of the container can be freely selected.
摘要:
A process for operating a hydraulic wash column, in which the position of the buildup front in the wash column is positioned by means of the flow rates of control liquor conducted into the wash column and/or by means of the flow rate of the suspension conducted into the wash column, and the flow rate determination is with the aid of the pressure difference which exists in the column between points in the suspension zone disposed upstream of the buildup front and points in the zone projecting from the buildup front up to the end of the crystal bed.

The present invention is directed to a method for adsorbing, i.e. non-covalently binding, nucleic acids to a solid phase using a two-step procedure. Furthermore, the present invention pertains to a method for isolating nucleic acids from a biological sample. In the first step of the procedure, lysis is effected by mixing the biological sample with an aqueous lysis buffer containing a chaotropic agent and incubating the mixture; in the second step, the concentration of the chaotropic agent in the mixture is increased and the mixture is contacted with the solid phase, whereby the nucleic acids in the liquid phase is adsorbed to the solid phase.
摘要:
A torsional vibration damper in a gearbox housing has an input part connected to a drive and acts on a first damping unit and an intermediate part which acts as the output of the first damping unit and as the input of a second damping unit. The torsional vibration damper further has an output part which is in working connection with the second damping unit and which is designed to accept a takeoff. Takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet. A sealing wall separates the torque-transmitting space from a damping space including the first damping unit.
