A hammer for installing a gasket into a joint between two pipes, the hammer comprising two opposed substantially rectangular, non-square strike surfaces which are rotationally offset from one another by 90 degrees such that an appropriate substantially rectangular, non-square strike surface may be selected by the user and applied to a gasket by simply rotating the hammer in the user's hands without requiring the user to relocate around the gasket.

A variable camshaft phaser is provided having a stator attached to a driving part, and a rotor located within the stator and attached to a driven part. First and second cover plates are located on respective first and second axial sides of the stator. Inwardly directed vanes of the stator, the rotor, and the first and second cover plates define at least one chamber. Radially outwardly directed vanes of the rotor divide the at least one chamber into an advance side working chamber and a retard side working chamber. A locking pin bore is located in the rotor, and a locking pin is located in the locking pin bore. One of the first and second cover plates includes a locking pin receiving opening. A magnetic part is located in the locking pin receiving opening to remove metallic particles and contaminants from the flow of pressurized hydraulic fluid.

A shrink-clamping and/or unshrink-unclamping station for tools, for an at least largely automated shrink-clamping and/or unshrink-unclamping of tools into and/or from tool holders includes an induction heating unit and a cooling unit. The cooling unit can in an automated manner be brought into a heat-conductive contact with a tool holder previously heated by the induction heating unit.

A method for a heating of a tool holder by means of an induction heating device for the purpose of a shrink-clamping and/or unshrink-unclamping of tools into and/or from tool holders includes an induction heating unit having at least one, preferably exclusively one, induction coil and is configured to expand by heating at least a portion of the tool holder, in particular at least a clamping region of the tool holder, in a shrink-clamping process or in an unshrink-unclamping process, and the induction coil is moved during an induction heating process.

A heater for shrink fit chucks has a heating cover, a blocking piece, and an adjustable blocking set. The heating cover has a first through hole, a second through hole, and a heating space disposed within the heating cover, extending along an extending direction to form the first through hole and the second through hole, and communicating with a heat gun. The blocking piece is detachably connected to the heating cover to block the first through hole and has a communicating hole capable of communicating with the first through hole. The adjustable blocking set is connected to the heating cover and has two blade assemblies and a switching component. Each blade assembly has blades disposed annular along the extending direction. The switching component is rotatable and capable of pushing the blades to move toward or depart from each other for blocking the second through hole.

A die-casting sleeve comprising an outer cylinder made of a low-thermal-expansion metal material, and an inner cylinder shrink-fit into the outer cylinder; an outer peripheral surface of the outer cylinder being provided with a flange for fixing the die-casting sleeve to a stationary die block of a die-casting machine; the inner cylinder being constituted by a front member of a low-thermal-expansion metal material arranged on the injection opening side, and a rear member of silicon-nitride-based ceramics arranged in close contact with a rear end surface of the front member; the outer cylinder having an average thermal expansion coefficient .sub.A of 110.sup.6/ C. to 510.sup.6/ C. between 20 C. and 200 C.; the front member having an average thermal expansion coefficient .sub.B of 110.sup.6/ C. to 510.sup.6/ C. between 20 C. and 200 C.; the difference between .sub.A and .sub.B being 110.sup.6/ C. to 110.sup.6/ C.; and the axial length L.sub.1 (mm) and inner diameter D.sub.in (mm) of the front member, and the distance L.sub.2 (mm) from a tip end of the outer cylinder to a rear end of the flange meeting D.sub.inL.sub.1L.sub.2+20.

A method and apparatus for assembling a suspension. In one embodiment, a method includes altering a temperature of a first suspension component and then pressing the first suspension component and a second suspension component into engagement while the temperature remains substantially altered.
