Abstract: Method for manufacturing an electrically operable heating body for an inhaler, wherein a semiconductor material is provided so as to be substantially planar, and a plurality of channels are incorporated into the semiconductor material substantially in the direction of the surface normal of the planar semiconductor material, such that a fluid can pass through the semiconductor material in the channels.

Abstract: A piston for an internal combustion engine has a piston body with a bottom. The piston body has at least two shaped sheet metal parts having monolithic flaps bent out of a radial plane of the piston body. The flaps are positioned at the bottom of the piston body. The flaps have eyes for at least one connecting rod. The piston is preferably designed without a skirt. Instead of the flaps, it is also possible to provide the bottom of the piston with a projection that is conical and tapers in a direction away from the bottom. The connecting rod is then connected to this projection.

Abstract: A reciprocating internal combustion engine has at least one cylinder with a reciprocating piston arranged therein. Two parallel crankshafts connected by a toothing rotate in opposite direction. Each one of the pistons has first and second rigid connecting rods, wherein the first connecting rod is connected to the first crankshaft and the second connecting rod is connected to the second crankshaft. Various connecting rod arrangements are possible. In one embodiment, the connecting rods are curved toward one another and toward a center axis of the cylinder. The piston may have two connecting rod bearings spaced apart in the direction in the spacing between the crankshafts. The first connecting rod connected to the first crankshaft may be connected to a connecting rod bearing that is remote from the crankshaft, and the second connecting rod connected to the second crankshaft may be connect to the other connecting rod bearing remote from the second crankshaft.

Abstract: A lobed rotor machine including an annular cylinder chamber having inlet and outlet openings, four working pistons movable in pairs in the cylinder chamber, two piston carriers for supporting respective pairs of the working cylinder and rotatable about a common machine axis and displaceable relative to each other, and guide channels formed inside of each of the two piston carriers and defining supply channels and return channels for communicating cooling medium to the pistons.

Abstract: A predominantly planar workpiece, having a surface which is punched-in and upwardly-arced, and forms a pocket with a lower surface, having a cutout portion identical to and aligned with a cutout portion of the upwardly-arced surface, such that a grasping device may be inserted into the pocket thus formed, and securely fastened therein, by means of an upwardly-arced semi-circular elevation which transverses the bottom part, such that the grasping device is securely locked within the pocket when inserted therein. A retaining part firmly connected to the grasping device for the acceptance of auxiliary parts remains essentially in the plane of the workpiece.

Abstract: A prefabricated inner roof lining for motor vehicles comprises interconnects, conductive layers or conductive networks in its surface and/or at its side facing away from the vehicle interior for supplying or distributing the electrical energy.

Abstract: A thermally insulating covering is provided incorporating a synthetic resin-impregnated carrier mat of fibers and an aluminum foil layer on that entire side of said carrier mat which is to face a heat source. A layer of insulating material is preferably located in predetermined areas between the carrier mat and the aluminum foil. A process for producing such covering is also provided.

Abstract: A process for producing a lining member, particularly a covering member, in which a fibrous material in single or multiple layer form is located with a binder preferably comprising a thermosettable polyester resin. Preferably a foam plate support layer is positioned at least on one side of the fibrous material which has been coated with a binder and such is preferably covered with a non-woven fabric layer. The assembly is compressed in a molding press. A ultrafine glass fiber non-woven fabric is used as the fibrous material layer.

Abstract: Process for producing a veneer workpiece in the form of a flat plate or the like with a preferably, at least partly wooden base layer, optionally in the form of a base veneer constituted by several individual layers, a face veneer having at least one wooden face veneer layer and a cutout passing through the base layer and the face veneer, in which the base layer and the face veneer are preferably glued together by means of a synthetic resin adhesive, which produces the cutout passing through the base layer and the face veneer and finally the circumferential wall or walls thereof are covered with face veneer material, characterized in that the gluing of the base layer and the face veneer to form a solid workpiece, the formation of the cutout or cutouts and the covering of the circumferential wall thereof with the face veneer in a single pressure punching process, the face veneer layer being pressed through from the surface of the veneer workpiece into the cutout or cutouts, while covering the circumferential w
