Abstract: A method and a filter device for the dry filtration of a gas flow carrying foreign objects in a filter device for purifying waste gas produced in additive manufacturing technologies, conducting a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side, feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface, such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form foreign objects containing oxides.

Abstract: A method for the dry filtration of a gas flow carrying foreign objects, a filter device for cleaning off waste gas resulting from additive manufacturing technologies, comprises feeding a raw gas flow containing foreign objects into a raw gas space of a filter unit having at least one filter surface separating a raw gas side from a clean gas side; feeding oxidant to a reaction region located on the raw gas side of the filter surface downstream of the filter surface; such that foreign objects contained in material cleaned off from the filter surface and/or in the raw gas flow react with the oxidant in the reaction region to form oxide-containing foreign objects.

Abstract: A high-level built-in oven unit having a housing with a heated cooking chamber having a floor opening therein. The chamber has a lowerable trap-door movable between a position closing the floor opening and a lowered position opening the floor opening. The trap-door is movable by a lifting device, which has lifting elements mounted outside of the cooking chamber.

Abstract: The invention relates to an oven comprising a sealing element (2) that, for sealing an oven door, rests only against a cool area (14) of an oven flange (4) without contacting the hot area (12) of the oven flange.

Abstract: A high-level built-in oven unit including a bottom opening in the oven unit. A removable trap-door including lifting elements to open and close the bottom opening of the oven unit. The trap door has a baking tray mounting arrangement detachably mounted thereon.

Abstract: The invention relates to an oven comprising a sealing element (2) that, for sealing an oven door, rests only against a cool area (14) of an oven flange (4) without contacting the hot area (12) of the oven flange.

Abstract: Wall-mounted cookers comprising a housing (38) with a hood and an oven (32) are known. The base of the hood has an opening, which can be closed by a base door (2) that can be lowered. A retaining part (19) of a device that retains a cooking product carrier is mounted on the upper side of the base door (2) facing the oven (32). According to the invention, to facilitate the cleaning of the retaining part (19), the latter (19) is detachably connected to the base door (2).

Abstract: A heating home appliance, in particular a household appliance such as an oven, includes an appliance space having at least one heating body. At least one multi-ply layer of air-tight foils at least partly surrounds the appliance space, enclosing air chambers, being at least peripherally joined together and otherwise being kept mutually spaced apart from one another. The at least one foil layer has foil edges, with an air-tight-sealed edge on all sides being formed of the foil edges and forming a flexible fastening and/or connecting element.

Abstract: A fixed-bed bioreactor with porous carrier bodies (14) for microorganisms. The carrier bodies are sheet-like structures with a small thickness in comparison with the carrier body surface. The carrier bodies are kept spaced apart by means of spacing bars (28), defining flow paths (36) between the carrier bodies. In a process for producing porous carrier bodies for microorganisms, plastics particles (70) are introduced into a moulding space (52) and bonded together therein by application of heat. With this process, an endless extrudate (46) of carrier body material may be produced, from which the individual carrier bodies may be cut off. Alternatively, the process may be carried out by means of a series of pairs of mould halves passing through a mould filling station and a heat supply station.

Abstract: A filter element for separating solid particles from a fluid medium. The filter element comprises a permeably porous, substantially inherently stable shaped body made substantially of polyethylene. The polyethylene is made from polyethylene grains combined and heated to form the shaped body. The polyethylene grains comprisean ultrahigh molecular polyethylene component including fine grains and having an average molecular weight of more than 10.sup.6. The polyethylene component further has, in an initial state before heating, a grain size distribution of at least 95% by weight of fine grains being larger than 63 microns and less than or equal to 250 microns. In addition, the polyethylene grains comprise a further polyethylene component including fine grains in an initial state before heating, and which has an average molecular weight of less than 10.sup.6.
