Abstract: A valve plate has a plate portion with a front side elastomeric seal fitted thereon, and a connection apparatus arranged at the rear side for connecting the valve plate to a carrier apparatus of a vacuum valve. The connection apparatus includes first and second elongate connection portions, the first connection portion is located at one side and the second connection portion is located at the other side of the longitudinal center of the plate portion, with each being connected to the plate portion with the two spaced-apart ends thereof. The connection portions are spaced apart from the plate portion in the region between the two ends thereof, with a respective slot formed between the plate portion and the respective connection portion, and have in a central region of the longitudinal extent thereof a connection structure for connection to an end portion of a respective valve rod of the carrier apparatus.

Abstract: A valve plate has a plate portion with an elastomeric seal on a front face and an elongated connecting portion spaced apart from a rear face by a slot for fastening the valve plate to a valve rod. The extension of the connecting portion in the width direction is defined by opposing first and second side edges of the connecting portion when viewed in a plan view of the rear face of the plate portion. A connecting structure is configured in the connecting portion in a central region of the longitudinal extension of the first side edge of the connecting portion for connecting the connecting portion to an end portion of the valve rod. The connecting portion is reinforced in a region of its extension in the width direction adjoining the second side edge, relative to a region of its extension in the width direction adjoining the first side edge.

Abstract: A stamping machine for labels and covers includes a servomotor as a driving element. The servomotor can be directly or indirectly connected to a spindle which causes the stamp to move forward in a linear manner.

Abstract: Some embodiments of the invention relate to a vacuum valve having at least one piston/cylinder arrangement for adjusting a first closure member between a first, a second, and a middle closure member position. In some embodiments, the piston/cylinder arrangement which is coupled mechanically to the first closure member has a cylinder unit and a piston unit. A first seal body and a second seal body can be displaced independently of one another axially relative to the cylinder unit and to the piston unit. A first axial stop of the cylinder unit and a third axial stop of the piston unit are arranged relative to one another such that, in the middle closure member position, the axial movability of the first seal body in the direction of a second pressure chamber is limited jointly by the first axial stop and the third axial stop.

Abstract: A heating system for a spray dryer has a heating element, a heating unit having an open-pore metal foam, and a fluid input and a fluid output. The metal foam is arranged between the fluid input and the fluid output so that fluid which flows in through the fluid input and out through the fluid output is laminarized. A method for simultaneously heating and laminarizing a fluid with the aid of an open-pore metal foam is also disclosed, as is an electrostatic precipitator having a sleeve-shaped electrode connected to a base part of the precipitator. Also disclosed is a device for detaching particles from an inner surface of a sleeve-shaped electrode, a method for detaching particles, and a spray dryer with a heating system as above and/or with an electrostatic precipitator.
