Abstract: A multi-part longitudinal drive shaft of a motor vehicle consists of two shaft sections that are each formed by a shaft tube connected with each other by a homokinetic displacement joint. The outer diameter of the shaft tube in the second shaft section is smaller than the inner diameter of the shaft tube of the first section. The outer joint ring of the homokinetic displacement joint is firmly connected with the shaft tube of the first shaft section and a ball hub of the joint is connected with the second shaft section. When a specific axial position is exceeded, the homokinetic displacement joint can be broken down. The individual parts of the two shaft sections can be displaced into one another, after break-down of the homokinetic displacement joint, so that the second shaft section is displaced in the direction of the first shaft section.

Abstract: The present invention relates to a self-cutting screw-in element, e.g., an artificial hip joint socket, having a lateral surface which is at least partially curved or buckled in the threaded area, and a thread interrupted by at least one flute having a thread tooth profile tilted in the feed direction, in which the cutting edge formed between flute and thread tooth is displaced on the side of the thread tooth opposite to the feed direction, and/or in which the inclination or twist direction of the flute runs opposite to the twist direction of the thread and the inclination or twist angle of the flute is larger than the pitch angle of the thread. A design of this type is advantageous for specific applications because the forces necessary for screwing-in may thus be significantly reduced without disadvantageous effect on the other properties.

Abstract: A quick release buckle assembly has a male portion and a female portion. The male portion is inserted into the female portion to lock the buckle assembly together. The male buckle portion is connected to a cable. Pulling the cable with sufficient force causes the male portion to release from the female portion. Several buckle assemblies can be simultaneously released if the cables are connected to a single handle. Pulling on the handle then releases all of the male portions at once.
