Abstract: A formwork for receptacles, especially round receptacles, has lining elements (10) that are detachably fastened to formwork elements (5) with anchoring elements (12) that project on their side facing away from the formwork element (5) from the latter so that after placing and setting of the concrete, the lining elements (10) remain adhering to the (concrete) wall 17 after the formwork elements (5) have been removed. After the formwork is dismantled, a receptacle (16) is obtained with a lining, especially an inside lining, its being sufficient to tightly seal the joints (14) between adjacent lining elements (10), for example with a joint filling mass 18.

Abstract: A touch-sensitive momentary-contact switch includes an infrared-radiation-emitting transmitter, an infrared-radiation-receiving receiver and at least one visible-light-emitting signal element. The transmitter, receiver and signal element radiate into a single light-guiding element. Due to optical beam guidance, a separation of a transmission channel and a reception channel in the light-guiding element is effected in such a way that at a top-side area of the light-guiding element remote from the transmitter and the receiver, a superimposition of a region that can be irradiated by the transmitter and a region that can be detected by the receiver is produced only on a small portion of the area. An operating device for a domestic appliance including at least one touch-sensitive momentary-contact switch, is also provided.

Abstract: Shuttering for containers, particularly for round containers, comprises lining elements (10) detachably fastened to the shuttering elements, the lining elements having anchoring elements (12) protruding from the shuttering elements (5) on the side facing away from the same, so that after filling and curing the concrete the lining elements (10) remain adhered to the (concrete) wall (17) after the shuttering elements (5) have been removed. After removing the shuttering, a container (16) having a lining, particularly an interior lining, is obtained, wherein it suffices to tightly seal the joints (14) between adjacent lining elements (10), for example, using a joint filling agent (18).

Abstract: A building has a frame which includes of several frame elements parallel to one another and located with a distance to one another. Each frame elements has two vertical supports and at least one horizontal beam. The frame elements are connected to one another to form the frame of the building by uprights which are attached outside to their vertical supports. To connect the supports, the beams and the uprights angles of steel sheet are used which in their legs have holes (19) for passage of connecting elements bent out and released from the legs of the angles, in the manner of nail plates. Connecting are located and attached between vertical supports. The girders (37) bear wall elements which adjoin stops on the vertical supports from the inside.

Abstract: A cylinder block and crankcase for a liquid-cooled internal-combustion engine is to be constructed by composite casting, a magnesium case being cast around an aluminum power unit block. The cylinder block and crankcase is conceived such that the aluminum power unit block is significantly used for the distribution of force between the cylinder head and the crankshaft bearing caps as well as for the guiding of the cooling water, in which case, the magnesium case is free of a cooling water guidance and predominantly used for the guiding of lubricating oil and, in addition, is correspondingly designed for the proportional stiffening against bending and torsion loads.

Abstract: For a machine housing with a split bearing arrangement, particularly journal bearing in piston machines, with a bearing cover clampably arranged via corresponding profiles on a bearing block, it is proposed that a bearing cover having a profile in its clamping face and acting as the tool electrode be used to produce by an electrical discharge machining process a corresponding profile in the clamping face of the bearing block of the machine housing serving as the workpiece electrode in order to achieve an advantageous formation of the profile. After the electrical discharge machining process, the bearing cover is mounted to the bearing block.

Abstract: To produce square beams from tree trunks (13), a device is proposed in which a tree trunk (13) is first positioned by a centering device (4) such that the lengthwise axis (14) of the tree trunk (13) assumes essentially always the same stipulated position. The tree trunk (13) is then grasped by holders (11, 12) of a carriage (8) concentrically to the lengthwise axis (14), whereupon the centering device (4) is opened. Then the tree trunk (13) is guided through a band saw (5) and trimmed on the opposite sides, whereupon it is turned by 90° and the two other sides of the tree trunk (13) are trimmed.

Abstract: A prefabricated wall panel for wood structures has a frame (1) which consists of two frame parts (2 and 3) and transverse links (4). The frame parts (2 and 3) consist of wooden boards (6) to (9) which define the outline of the frame parts (2 and 3). The frame parts (2, 3) can be stiffened by additional boards (10 to 12) which are arranged to run obliquely. Everywhere the boards which form the frame parts (2 and 3) abut one another they are joined to one another by nail plates (14, 15 and 16). The transverse links (4) which join the frame parts (2 and 3) to one another to form the frame (1) are likewise boards with a length which determines the distance between the frame parts (2 and 3) and the space which is available for heat and/or sound insulation. It is also advantageous that the prefabricated wall panel as claimed in the invention with its frame (1) can be assembled on site.

Abstract: To make the usable wood volume of the tree trunks as large as possible, octagonal or dodecagonal dressed timbers are proposed from which then boards or beams with inclined edges are cut. To produce octagonal or dodecagonal dressed timbers, in a first machining stage (11) two side surfaces (13) are milled off the tree trunk, it is then turned by 90° and two additional side surfaces (19) are milled off in a second machining station (17). Immediately thereafter in another machining station (21) with four (for octagonal dressed timbers) or eight (for dodecagonal dressed timbers) milling cutters (22) the remaining rough edges (20) are milled off.

Abstract: A travelling device for hauling timber has a loading ramp (4) for the wood and a loading crane (5). Two cable drums (12, 13) with cables (18, 19) are attached to one frame (1), and one cable (19) can be attached in front of and the other cable (18) behind the device at a stationary point (20), and each cable drum (12, 13) can be driven for purposes of winding up the cable assigned to it. Using the cables (18, 19) the device can also be moved on steep or swampy terrain in which it is no longer possible to continue to move by means of conventional drives.

Abstract: A device for producing squared timber from tree trunks includes a feed section, a machining center, and a delivery section; the feed section has at least two grippers which can be placed against the tree trunk to be machined and using which the tree trunk is supplied to the machining center; the machining center has several plan cutters and feed rollers in order to advance the tree trunk, while it is machined by cutting at the desired locations. The square beam is transported from the machining center onto the delivery section and then removed for further machining. The grippers may be made such that they hold the tree trunk regardless of its diameter at a height which at least roughly corresponds to the axis of the machining center.

Abstract: A connection arrangement for secondary distribution systems which effects a connection in the state free of short circuits, within permissible performance quantities, by means of at least one interrupter assembly. Besides current and voltage sensors with a processing module, a connection branch parallel to the load, and a bridge branch, along the lines of a voltage divider, are also used to safeguard against making operations in case of a short circuit. The interrupter assembly is bridged by the bridge branch which, according to the function, contains an ON switch. In the event of a short circuit, the voltage at the actuating element does not suffice to close the interrupter assembly.

Abstract: A process for producing beams of square cross-section from tree boles or the like is characterized in that plano-convex slabs are severed in parallel to the hart zone of the boles. An apparatus for performing the process is characterized in that the boles (2) are supported by height-adjustable supports (9, 10) in such a way that the heart zone (8) is congruent with the preferably horizontal feeding direction of the bole (2). Thereby, the thus-produced square beam (7) is defined by planes parallel to the heart zone.
