Abstract: A cylinder head for a direct-injection spark-ignition internal combustion engine includes, for each cylinder, an inlet valve, an exhaust valve, a first receptacle, a second receptacle, and a third receptacle. The first, second, and third receptacles are respectively configured to receive an ignition device or an injection device. The first receptacle extends substantially parallel to the inlet valve. The second receptacle extends substantially parallel to the exhaust valve. A common camshaft is offset from a cylinder center plane and actuates the inlet valve and the exhaust valve via identically constructed valve actuating elements. The cylinder head is lightweight, compact and easy to assemble and is in particular suited for high performance engines.

Abstract: A roll stand comprises a frame, a pair of upper guide members spaced apart on the frame along an upper axis and a pair of lower guide members spaced apart on the frame along a lower axis parallel to the upper axis. Guide formations between the members and the frame prevent the members from moving axially relative to the frame and permit the members to move vertically in the frame. Respective upper and lower journal blocks on the members are prevented from moving vertically relative to the respective members by respective guide formations between the blocks and the members but can move axially on the members. An upper roller is carried between the upper journal blocks, axially coupled thereto, and rotatable thereon about the upper axis and a lower roller is carried between the lower journal blocks, axially coupled thereto, and rotatable thereon about the lower axis.

Abstract: A coupling is provided in which a coupling member and coupling sleeve of a rotary coupling for coupling a drive transmission to a rolling mill stand input shaft have mating taper threads which provide torsional rigidity and facilitate quick engagement and release. Engagement and release are effected by slowly turning the coupling half by means of the drive transmission while a brake device engages dogs on the coupling half to prevent the latter rotating. The coupling sleeve is flexibly attached to the flange by sheet metal laminate compensating elements but mobility of the sleeve is restricted by a support element on a shaft extension.

Abstract: An apparatus and method is provided for feeding, clamping and removing bar or tube goods in tube test presses which have a bearing surface consisting of several supporting crossbeams spaced parallel to each other, and at least two disk-like driven rotors having at least one hook-like peripheral projection spaced on at least one axis of rotation, where each axis of rotation runs crosswise to the crossbeams under their bearing surfaces, such that only hook-like peripheral extensions of the rotors project above the bearing surfaces for transporting and clamping the goods, the improvement comprising at least one tenterhook pivotable adjacent the bearing surface between a first position below the bearing surface and a second position above the bearing surface of the crossbeam and parallel to the rotor adjacent each rotor, and which, pivoted to said second position above the bearing surface during clamping, grips the goods on side opposite the adjacent rotor involved.

Abstract: A rolling block for rolling a bar-shaped article having several rolling units mounted on a common frame, each rolling unit having three or more rollers journalled to respective pivotable elements and defining a sizing pass. For replacing the rollers, the pivotable elements can be swung about respective drive shafts from which the rollers are driven via step-up transmissions within the pivotable elements. The pivotable elements can be locked in their operative positions by hydraulically actuable coupling means and all the pivotable elements with the respective rollers therein can be fine-adjusted in the radial direction of the rollers.
