Abstract: A domestic appliance for processing foods including: a bowl, with an opening for introducing foods into the bowl and into which a tool for processing foods is inserted, a splash guard, which can be inserted into the opening of the bowl, such that boundary regions of the splash guard are opposite an inner wall of the opening to prevent foods from spraying out of the bowl, and a cover, which can be inserted into the opening of the bowl once the splash guard has been inserted into the opening of the bowl, wherein the splash guard includes a plate which extends substantially flat and ends with boundary regions.

Abstract: A filter device is for the filtration of gases contaminated with particles, such as welding gases, in particular produced in manufacturing processes using 3D printers in a production room (52). The filter device has a filter circuit having at least one filter element (55, 56), which filters the particles from the gas. At least a part of those particles get from this filter element (55, 56) into an assignable receptacle (59). The particles within a back-flushing process get into the respective receptacle (59). At least one further filter circuit has at least one further filter element (NF1, NF2 that filters a fluid having the particles obtained at the back-flushing process.

Abstract: A filter device for transmission oil has a filter element (24) insertable into a transmission oil pan (70) with a filter medium (32) separating an unfiltered side from a filtrate chamber connected to an outlet (38, 50, 72), to which a suction oil pump can be connected. The filter medium (32) has a first structural layer (46) having a predetermined surface area and predeterminable filter properties and has a second structural layer (44, 60) having predeterminable filter properties. The surface area of the second structural layer (44; 60) is different from the surface area of the first structural layer (46). The structural layers (44, 46, 60) encompass an inner filter cavity (30) and are pleated having the same type of pleats. The pleated structural layers (44, 46, 60) extend in axial alignment between two end caps (22, 34) of the filter element (24).

Abstract: 1. Filter device for the filtration of gases contaminated with particles. 2. A filter device for the filtration of gases contaminated with particles, such as welding gases, which are in particular produced in manufacturing processes using 3D printers in a production room (52), having a filter circuit having at least one filter element (55, 56), which filters the particles from the gas, wherein at least a part of said particles get from this filter element (55, 56) into an assignable receptacle (59), is characterized in that the particles within a back-flushing process get into the respective receptacle (59), and in that at least one further filter circuit, having at least one further filter element (NF1, NF2), is present, which filters a fluid, which has the particles obtained at the back-flushing process.

Abstract: A filter device for transmission oil, having a filter element (24) which can be inserted into a transmission oil pan (70) and the filter medium (32) of which separates an unfiltered side from a filtrate chamber, which is connected in a fluid-conveying manner to an outlet (38, 50, 72), to which a negative-pressure device such as a suction oil pump, can be connected, wherein the filter medium (32) of the filter element (24) has at least one structural layer (46) having a predetermined surface area and predeterminable filter properties and having at least one further structural layer (44, 60) having predeterminable filter properties, wherein the surface area of the further structural layer (44; 60) is different from the surface area of the first structural layer (46), and wherein the respective structural layers (44, 46, 60) encompass an inner filter cavity (30), is characterized in that the respective structural layers (44, 46, 60) are pleated having the same type of pleats, in that the pleated structural layer

Abstract: The invention relates to a method for producing a filter element (1), comprising a first filter medium (2), which has individual filter folds (4), and a second filter medium, which surrounds at least sections of the filter folds (4) in the manner of a mat-like filter jacket (6) that is composed of individual fibres (5).

Abstract: The invention relates to a filter device for fluids, particularly hydraulic or lubricating oils, having a filter element (1) comprising at least one inflow region (5) for a fluid to be cleaned, characterized in that an adapter element (7) covering the inflow region (5) and forming a trap device for organic substances such as fatty particles and colloidal oil aging products may be attached to the filter element (1).
