A whole blood filtration device is provided with a filter membrane separating a feeding volume and a clean side of the filter membrane from each other. The feeding volume communicates with a first feeding side opening and with a second feeding side opening. The filter membrane has pores with a pore size that ensures permeability of the filter membrane to blood plasma/serum and that retains blood cells. The first feeding side opening can be coupled to a first blood pump for feeding blood from the first feeding side opening into the feeding volume so that blood plasma/serum permeates the filter membrane and blood cells, retained by the filter membrane, exit from the feeding volume through the second feeding side opening.

A thermally sterilizable fluid filter () for concentrating substances contained in a fluid by way of micro-, nano- or ultrafiltration of the fluid, particularly for concentrating a pharmaceutical precursor and/or intermediate, in particular a vaccine, in a fluid. The fluid filter has a filter housing with a fluid inlet, a retentate outlet and a permeate outlet. A filter cartridge is arranged in the filter housing () and has a filter medium of a ceramic material and/or a ceramic composite material. The filter cartridge is held with axial play on the filter housing.

A blood filtering device has a filtration section with filter medium separating raw side and clean side. A first communication path connects raw side and a first variable blood reservoir volume; a second communication path connects raw side and a second variable blood reservoir volume coupled to a receptacle. When varying the first variable blood reservoir volume, blood contained therein flows through first communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through second communication path into the second variable blood reservoir volume. When varying the second variable blood reservoir volume, blood contained therein flows through second communication path to raw side, plasma/serum passes through the filter medium from raw side to clean side, and residual blood flows from raw side through first communication path into first variable blood reservoir volume.

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. The membranes are enclosed at the edges at least in sections by an enclosing part, wherein the enclosing parts of membranes lying one above the other are directly connected to one another in a flow-tight manner.

Humidifier, in particular for a fuel cell

A humidifier has a stack unit having a plurality of water-vapor-permeable membranes which are arranged parallel one above the other and spaced apart from one another. Two adjacent membranes are connected to one another via fixing elements, wherein a first fixing element acts on the top membrane from above and a second fixing element acts on the bottom membrane from below.

A venting device for a housing, for example, a battery housing, has a gas-permeable and liquid-impermeable membrane attached to the housing so as to close off a venting opening of the housing. The membrane has a membrane section that overlaps and covers the venting opening. The membrane section has a predetermined bursting pressure. The membrane section deforms without being destroyed when pressure differences between the interior of the housing and the environment occur that are below the bursting pressure and when gas passes through the membrane section.

A filter pipeline for an air intake system of an internal combustion engine has a tubular body and a filter element arranged in the tubular body. The filter element is a filter bag of a flexible material that has an opening and is attachable in the area of the opening to the tubular body. The filter bag and an inner wall of the tubular body are provided with ribs projecting inwardly from the tubular body such that in a circumferential direction of the pipeline different spacings are provided between the filter bag and the inner wall of the tubular body.

Filter pipeline

The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. The pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the pipe interior.

The filter element is a filter bag of a flexible material that has an opening and is attachable in the area of the opening to the tubular body. The filter bag and an inner wall of the tubular body are shaped such that in a circumferential direction of the pipeline different spacings are provided between the filter bag and the inner wall of the tubular body.

A filter element comprising a filter medium which extends through an axial length between an end face at a clean air end and an end face at an unfiltered air end such that the filter medium separates an unfiltered air end of the filter element from a clean air end, in which the filter medium is circumferentially surrounded by a jacket and attached in a sealed manner to the jacket, and in which contours for securing the filter element in a filter housing are arranged on the jacket of the filter element.

A rocker cover assembly for a cylinder head of an internal combustion engine includes a rock cover, a gasket element and a stabilizing core. The gasket element is disposed between the rocker cover and the cylinder head, and includes a sealing material. The stabilizing core is inserted in the gasket element and surrounded at least essentially completely by the sealing material of the gasket element. The stabilizing core is isolated from the rocker cover such that the sealing material of the gasket element is arranged between the stabilizing core and the rocker cover.

An intake system for an internal combustion engine of a motor vehicle, which includes a first air intake which is arranged at a point in the motor vehicle that is advantageous for air intake, and a second air intake which is arranged at a point that is protected from road spray and splashes of water. The two air intakes end in a common line that communicates with the internal combustion engine. In the first air intake a moisture sensor is arranged. When water enters into the first air intake this moisture sensor emits a signal that actuates a solenoid to move a pivotable valve In a first switching position pivotable valve closes the second air intake so that no air reaches line from the second air intake In a second position (shown in broken lines) pivotable valve closes the first air intake so that air reaches line only through the second air intake
