A hip joint prosthesis comprises a femoral component having an elongated shank formed of a metal alloy and a joint head adapted to cooperate with the natural acetabulum or a prosthetic acetabulum likewise formed of a metal alloy. The shank has approximately the same width in the lateral-medial plane and a slightly downwards tapered width in the anterior-posterior plane.

A device forms a splice between a moving web of a terminating roll and a web of a new roll in either one of two positions. The device has a pressure arm assembly, which has a pressure roll and a cutting device for severing the moving web from the terminating roll after formation of the splice and an acceleration arm assembly which has an acceleration roller and a motor for driving the roller with one of the two assemblies being constructed so that it can pass through an opening in the other assembly to shift the two assemblies from an "IN" splicing position, wherein the new roll is rotated in a clockwise direction to a "OUT" splicing position wherein the new roll is rotated in a counterclockwise position.

Apparatus for assuring the in-register positioning of a cutting plate on a cutting cylinder, preferably a magnetic cylinder in a rotary printing machine. The apparatus comprises a contact plate which is arranged tangentially to the cutting cylinder. The contact plate is formed with a slot running axially parallel to the cylinder for the purpose of receiving the cutting plate, the slot having an edge which serves as a stop. An axially parallel measuring bar is positioned along the cylinder length and is parallel to the contact plate. Extending around the circumference of the cutting cylinder is a second measuring bar which crosses the first measuring bar.
