Abstract: A method for connecting a wheel, such as a turbine wheel or compressor wheel, in a turbine wheel rotor. The method includes providing a shaft made of steel, and pouring a casting alloy around an end of the shaft, wherein the casting alloy includes an intermetallic compound of the system TiAl. The method is particularly well-suited making a connection of the turbine wheel and the shaft of an exhaust-gas turbocharger for motor vehicles using a casting process. In addition, a turbine wheel rotor, that includes a steel shaft, a cast wheel including a casting alloy fixedly connected to an end of the shaft. The casting alloy including an intermetallic compound of the system TiAl. A connection between the cast wheel and the shaft includes at least one of a friction fit, a positive fit, and an integral connection.

Abstract: For making an interconnection between a valve head and stem, the interconnection between these parts is made by pouring a cast alloy around the stem end. A connection and a valve are also provided.

Abstract: To produce precision castings from a melt, use is made of a metallic casting wheel (1) which has an annular distribution channel (4) and a plurality of interchangeable casting moulds (6), each having at least one filling opening (6a). The melt quantity per casting operation is chosen here such that the casting moulds (6) and the distribution channel (4) are filled with the melt upon the rotation of the casting wheel (1) about its axis (A—A), in such a way that after the solidification of the melt the precision castings are held together by a ring of the casting material which is formed in the distribution channel (4), the so-called circulating material for new casting processes, and are removed from the casting wheel (1) together with the casting moulds (6), whereupon the precision castings are separated from the ring.

Abstract: Molds (1) with annular mold parts (2, 3) divided by at least one plane of division (E—E) and forming a plurality of cavities (8) disposed at least substantially radially to a centrifugation axis (A—A), serve for the production of precision castings by centrifugal casting, especially of parts made of materials containing titanium for internal combustion engines, the molds (1) and a casting system being contained in a closed chamber. To automate production, at least one mold part (2, 3) is made to rotate in its own rotational guide, and two mold parts (2, 3) together with the corresponding rotational guides are brought to a closed position for the casting and solidification and to an open position for the removal of the precision castings. When cast, the precision castings are preferably joined together at their radially inward pointing ends by a circumferential ring of the solidified metal and thus a circle of castings can be removed from the opened mold by a manipulating system.

Abstract: The invention relates to a locking device for bicycles having a nut which can be screwed on a threaded stud on the bicycle, a lock section and a cap, the base of which, with the nut on its thread, is between the nut on its thread, is between the nut and the frame or saddle post, its cylindrical wall surrounds the nut and ends in the region of the face of the nut and, when tightened, can rotate freely, where the surfaces of the nuts of several bicycles differ from one another and the part of the lock section of a bicycle accepting the nuts matches certain nuts on that bicycle. The lock section takes the form of a unique lock (2), the outside surfaces of the nuts (1) differ, and the cap (3) is at a short distance from the part of the nut (1) which projects furthest radially outwards. The locking device provides security against the theft of bicycles and their components.

Abstract: The invention relates to a furniture fitting in the form of a cup-shaped hinge housing which can be anchored into a bore of a furniture door and used as a door side pivot carrier for a furniture hinge. The hinge housing has a locking element which can be rotated about an axis at right angles to a circumferential wall and which has a section for holding the locking element when it is in a locked position. In a preferred embodiment of the hinge housing, two swivelling locking elements are provided which are connected to each other by a bracket shaped element so that when the bracket shaped element is swivelled to a given position by hand the locking element is moved into a locking position.

Abstract: A hinge component for pivotally connecting two parts of a piece of furniture includes a fastener member adapted to be attached to one part of the furniture, a carrier member mounted in the fastener member for adjustable displacement relative thereto along a first axis, and a hinge arm member which carries a hinge shaft defining the pivotal axis of the hinge component. The hinge arm member is mounted in a guide groove formed in the carrier member for adjustable displacement relative thereto along a second axis perpendicular to the first axis. After the carrier member is adjusted relative to the fastener member, and the hinge arm member is adjusted relative to the carrier member, the hinge arm member can be clamped between the carrier and fastener members. Thereafter, the hinge arm member can be adjustably displaced relative to both the fastener and carrier members along a third axis perpendicular to both the first and second axis thus providing three degrees of freedom for the hinge shaft.

Abstract: The present invention relates to a fitting for the detachable connecting of structural parts, and particularly of flat structural or cabinet parts. The fitting consists of a locking element which is rotatably inserted in a first construction part and of a connecting member which can be anchored in a second construction part and which cooperates, for the clamping together of the structural parts, with a first eccentric surface on the locking element. The fitting is developed in the manner that the connecting member has a bolt-shaped or pin-shaped element or clamping pin which is adapted to be displaced by the first eccentric surface relative to the locking element upon the turning of the latter in order to anchor the connecting member in the second structural part.

Abstract: This invention relates to a fitting for the detachable connecting of two structural parts which abut perpendicularly to each other, particularly cabinet parts, having a preferably cylindrical or partially cylindrical holding piece which can be inserted into a recess, open towards one surface side, in a first structural part, and having a connecting piece which can be anchored in a recess of the second structural part as well as on the holding piece. The connecting piece in the second structural part can be anchored relative to the connecting piece by displacement of the holding piece.

Abstract: The fastening fitting is used for detachable connection of two structural members, especially for detachable connection of two structural members butting together at right angles, for example a furniture side wall with a furniture top panel, a furniture floor, a furniture intermediate floor, and so on. This fitting comprises a holding element, which can be inserted into a hole of a first structural member, a pin which can be inserted into a hole in the second structural member and an anchoring screw which engages with an opening in the pin. The pin and the holding element are connected by a compressible section preferably by an elastically compressible section, which section can be compressed at least in direction of the anchoring screw. At a preferred embodiment the holding element, the pin and the compressible section are integrally made or formed as one unit.
