Abstract: A device is for producing a component from a plastics material by injection moulding. The device includes two mould halves that can be pressed together releasably and, in the pressed-together state, form at least one gate region and at least one common cavity for moulding the plastics material. The gate region is fluidically connected to the cavity for the purpose of introducing the plastics material into the cavity. At least one insert part is provided which is arranged at least partially in a partial region of the gate region and is formed to prevent or at least to impede flowing of the plastics material through this partial region.

Abstract: A water separating screen for a filter element in a liquid filter, the water separating screen including: a screen fabric having end faces; and a fabric carrier; a screen fabric arranged on the fabric carrier and encircling a longitudinal axis, the screen fabric having axial end faces, the longitudinal axis defining an axial direction; wherein the fabric carrier in an area between the end faces exclusively has longitudinal struts, which at least substantially extend in the direction of the longitudinal axis and which are elastic in a radial direction.

Abstract: A fluid pump, in particular an oil pump, for supplying a clutch actuator, a gearbox actuator, a lubrication system, and/or a cooling system of a drive train, includes a pump unit, an electrical drive unit, and a one-piece sealing element. The pump unit is arranged in a first housing part of the fluid pump, and the electrical drive unit is arranged in a second housing part of the fluid pump. The one-piece sealing element seals the first housing part against the second housing part, and seals the first housing part against a housing cover arranged on a side opposite the second housing part. Furthermore, a method for producing such a fluid pump includes arranging a pump unit in a first housing part of the fluid pump and moulding a sealing element onto the first housing part.

Abstract: A filter medium comprising: a first media layer; a second media layer; and at least one third media layer; wherein the second media layer is arranged downstream from the first media layer in the intended direction of flow of the filter medium; wherein the third media layer is arranged downstream from the second media layer in the intended direction of flow through the filter medium; wherein the first media layer has a degree of particle separation, which is lower than the degree of particle separation of the second media layer; wherein the second media layer has a degree of particle separation which is lower than the degree of particle separation of the third media layer; and wherein the media layers are arranged loosely and not bonded to one another, or are arranged loosely and bonded in a spot-bonded manner.

Abstract: The present disclosure relates to electrolysis. The teachings thereof may be embodied in a reduction process and/or an electrolysis system for electrochemical carbon dioxide utilization wherein carbon dioxide is introduced into an electrolysis cell and reduced at a cathode. For example, an electrolysis system for carbon dioxide utilization may comprise: an electrolyzer including an anode in an anode space and a cathode in a cathode space. The cathode space has an entrance for carbon dioxide. The cathode space comprises a catholyte including alkali metal cations. The anode space has an entrance for an anolyte. The anode space comprises an anolyte comprising chlorine anions.

For example, an electrolysis system for carbon dioxide utilization may include: an electrolysis cell with an anode in an anode space, a cathode in a cathode space, and a membrane; a first feed for carbon dioxide into the cathode space, configured to bring the carbon dioxide into contact with the cathode; a proton donor unit; and a second feed for protons configured to bring the protons into the cathode space from the proton donor unit into contact with the cathode.

Abstract: A filter medium of a filter element for filtering a fluid has at least one nonwoven filter layer of synthetic individual fibers. The filter layer has an increasing level of compression in a flow direction of a fluid passing through the filter medium. The filter medium has a degree of separation for particles to be filtered that increases in the flow direction of the fluid through the filter medium. The filter medium is used in a filter element for filtering fluids such as fuel or air. In a method for producing the filter medium, the synthetic fibers are deposited on a support surface in such a way that an increasing level of compression is created in a direction toward the support surface by gravity and suction acting on the fibers.

Abstract: A liquid filter for water separation and/or particle filtration of a fuel and/or aqueous solution, in particular a urea solution, and/or water, in particular in a motor vehicle, is described. The liquid filter has at least one filter and/or coalescer medium that is made of a non-woven fabric that has fibers and/or threads having elementary silver.

Abstract: A filter medium (10) has a first layer of media (12), a second layer of media (18), and at least one third layer of media (20). The second layer of media (18) is arranged behind the first layer of media (12) in the intended flow direction (16) of the filter medium, and the third layer of media (20) is arranged behind the second layer of media (18) in the intended flow direction (16) of the filter medium. The first layer of media (12) has fibers, and the second layer of media (18) has nanofibers. Also disclosed is a filter element (50) which has such a filter medium (10) and the use of such a filter medium (50) as a fuel filter.
