Abstract: An apparatus for the metered removal of bulk material from a bin, the apparatus having a top bulk-material-filling opening, bottom bulk-material-removal opening, and a rotor that is connected in a driven manner to at least one sweeping arm disposed inside the bin near the bin's rotationally symmetrical floor and directed towards the removal opening. In order to create an apparatus for the removal of bulk material from a bin in which the mass of the removed bulk material not only can be metered very precisely, but which is also of simple design and easy to maintain, provision is made whereby the sweeping arm is attached on the bottom side of a separating element connected in a driven manner to the rotor, and whereby a settling zone is provided below the separating element in front of the sweeping arm, this zone only being open on one side to the bulk material through a feed opening, and on the other side to the removal opening.

Abstract: A curtain coater for coating a substrate, comprising: a nozzle system for creating a curtain of at least one coating fluid dropping onto the substrate, a porous curtain guide structure, which has a guide surface for providing a lateral guiding action for the curtain, which cambers round convexly towards the curtain across a width extending beyond the thickness of the curtain measured transversely to the curtain, at least one cavity extending in the longitudinal direction of the curtain guide structure for an auxiliary fluid to be guided on the guide surface and a cavity wall surrounding the cavity, of which the curtain guide structure forms only a circumferential segment, and the circumferential segment bounding the cavity is a part of an external contour of the curtain guide structure extending about a longitudinal axis of the curtain structure.

Abstract: 1. Cylinder Head Gasket 2. In a cylinder head gasket (1) for an internal combustion piston engine, having at least one gasket layer (21, 23, 25) of metallic material which defines the main gasket plane and which has at least one combustion chamber through opening (3), on the edge of which there is a circular ring-shaped combustion chamber sealing area (15), the combustion chamber sealing area (15) is vertically profiled such that measured perpendicular to the main gasket plane it has a different thickness in different peripheral areas.

Abstract: In a flat gasket, especially a cylinder head gasket, having at least one elongated, metallic carrier element (17) which extends over several sealing zones, preferably over several combustion chamber sealing zones (41) for several in-line cylinders of a piston engine, the carrier element (17) is formed by several component elements (7, 9, 11) which are interconnected by a connecting means (23, 35), abutting one another (at 13).

Abstract: A curtain coater for coating a moved substrate , with a nozzle system for creating a curtain comprising at least one coating liquid falling onto the substrate ; a side edge splitting device which splits off an edge of the falling curtain at an outer end after leaving the nozzle system and thus bounds its width; and a curtain guide structure, with a guide which guides the curtain at the side, mounted with the side edge splitting device such that the side edge splitting device and the curtain guide structure are adjustable as a unit in the width direction relative to the nozzle system.

Abstract: A curtain coating device for the coating of a moving substrate, comprising a nozzle device, for the generation of a curtain dropping onto the substrate, made up of at least one coating fluid and a curtain guide structure with a guide surface, which laterally guides the curtain, whereby the guide surface is convex to the curtain along a width exceeding the depth of the curtain when measured transversely. Additionally, a curtain coating method, whereby a curtain made up of at least one coating fluid is deposited on a moving substrate in free fall and guided on both sides by means of a convex guide surface transverse to the curtain.

Abstract: A liquid film coating process is provided in which a curtain (5) from at least one coating fluid (1) is poured on an object (10) being conveyed at right angles to the curtain (5). A fluid coating (6) is formed on the object (10) as a result. A mixture of a coating material and an organic carrier liquid, which has a surface tension of at most 40 mN/m, is used as the coating fluid (1). The fluid coating (6) is solidified to form the final coating. To solidify the fluid coating either the organic liquid is removed from the fluid coating formed from the mixture on the object by evaporation or a liquid that can be polymerized by heating is used as the organic liquid in order to solidify the fluid coating formed on the object by polymerizing the organic liquid.

Abstract: A check valve is provided and has a housing having inlet and outlet openings and comprising two essentially planar plate portions. A thin steel plate that acts as a valve is disposed between the plate portions. Under the effective pressure, the valve opens in one direction and blocks flow in the opposite direction. The valve has at least one valve tongue, and the plate portions in the valve are fixedly connected together. One of the plate portions is associated with the discharge zone and in the vicinity of the valve tongue is provided with at least one arched portion for limiting opening of the valve tongue. The other plate portion has bores through which the exhaust gas can enter under overpressure.

Abstract: A method for curtain coating a moving support with a liquid coating material. An evacuating device is utilized to evacuate air carried along with the moving support. A device for carrying out the method includes a pourer having a pourer lip, a pouring roll carrying a support, and an evacuating device which is disposed in front of the curtain. The evacuating device includes an evacuating blade having a front edge facing the curtain. The front edge is provided with a slot which is connected to a vacuum installation. The method and device allow a substantial stabilization of the curtain at its point of contact with the support.
