A method and apparatus for transporting loads includes a gripper pliers including a pair of pivotable gripper arms, each of which has a gripper claw. A positioning element is operatively coupled to the pair of gripper arms for pivoting the gripper arms in a pivoting plane and displacing the gripper arms in a gripping direction transversely of the pivoting plane into a position so that the gripper claws can engage connecting regions of the load. At least one of the gripper arms includes a transverse guide for fixing it against further pivoting and back-pivoting within the pivoting plane after the gripper arm has pivoted into an operating position for being displaced in the gripping direction.

A lock cylinder having: a cylinder core having a key channel for inserting a key which is provided with profiling; at least one feeler element which is disposed in the cylinder core, is acted on by a spring and is held in a blocking position by the spring when the key is not inserted in the key channel; and a blocking element which, when the feeler element is in the blocking position, is held in a blocking position which blocks rotation of the cylinder core. The feeler element can be shifted against the return force of the spring into a release position by the profiling on the matching key inserted into the key channel, in which position the locking element can be deflected into a position releasing the cylinder core. In order to enable the lock cylinder to lock more securely, the feeler element includes a feeler arm for feeling the profiling, which feeler arm protrudes radially from a shaft rotatably supported in the cylinder core and which feeler arm, when the matching key is inserted, is acted upon such that the shaft rotates about the axis thereof into the release position.

The invention relates to the field of ceramics and relates to composite molded articles, such are used, for example, for chip-removal tools. The object of the invention is to disclose composite molded articles that are free in the design of their surface and interface and can be produced in series production. The object is attained through ceramic and/or powder metallurgical composite molded articles comprising a green tape and an injection molded article. The object is further attained through a method in which a green tape is inserted into or placed onto a mold, and subsequently at least one ceramic and/or powder metallurgical injection molding mass is placed on and/or applied to and/or inserted into the mold by means of injection molding, and subsequently the one-part or multi-part mold is removed and/or the one-part or multi-part composite molded part parts are removed from the mold, wherein these process steps can be repeated once or several times.

The invention relates to the field of material sciences and relates to a metal-ceramic composite with good adhesive strength, such as can be used, for example, for forming tools or cutting tools. The object of the present invention lies in the disclosure of a metal-ceramic composite with good adhesive strength which has a strong and durable bond between ceramic and metal. The object is attained with a metal-ceramic composite with good adhesive strength, comprising a metal component and a ceramic component and which are connected to one another by adhesive force or by adhesive force and in a non-positive manner, wherein silicon, beryllium, titanium, chromium, nickel, manganese, hafnium, vanadium, zirconium, aluminum and/or the organic compounds thereof is present in the area of the connection surfaces and wherein the components have been processed as a greenbody to form a composite and jointly sintered. The object is further attained through a method in which at least respectively one metal component and ceramic component are connected as a total greenbody and jointly subjected to a temperature treatment, at least for sintering the ceramic components.

A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided. To enable rotary motions of the shaft end relative to the wedge-shaped pieces, the latter adjoin one another without gaps in the circumferential direction, forming an encompassing wedge-shaped sleeve, whose inside diameter is slightly larger than the outside diameter of the shaft end of the gas exchange valve, and that the protrusions and recesses mesh with one another with slight play.

The invention relates to a lock cylinder comprising: a cylinder core (2) having a key channel (7) for inserting a key (5) which is provided with profiling (18); at least one feeler element (9) which is disposed in the cylinder core (2), is acted on by a spring (8) and is held in a blocking position by the spring (8) when the key (5) is not inserted in the key channel (7); and a blocking element (13) which, when the feeler element (9) is in the blocking position, is held in a blocking position which blocks rotation of the cylinder core (2), it being possible for the feeler element (9) to be shifted against the return force of the spring (8) into a release position by the profiling (18) on the matching key (5) inserted into the key channel (7), in which position the locking element (13) can be deflected into a position releasing the cylinder core (2). In order to enable said lock cylinder to lock more securely, the feeler element (9) comprises a feeler arm (10) for feeling the profiling (18), which feeler arm (10) protrudes radially from a shaft (11) rotatably supported in the cylinder core (2) and which feeler arm (10), when the matching key (5) is inserted, is acted upon such that the shaft (11) rotates about the axis thereof into the release position. The invention further relates to a locking device consisting of a lock cylinder and a matching key.
