Abstract: The drive mechanism for the feed roll of a combing machine employs a freewheel having an inner member secured to the feed roll and a concentric outer member secured to the pivotal arm which mounts the top nipper. In addition, locking elements are disposed between the inner and outer members and the outer member provided with a sawtooth configuration so that the locking elements may lock during rotation of the outer member under the influence of the arm and may move into a released position during an opposite rotation of the outer member. The lost motion or idle travel in the changeover between the released position and the locking position is quite reduced. Thus, feeds are always of substantially exactly the same magnitude with a resulting improvement in the produced sliver.

Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there.

Abstract: A process and an arrangement for producing a supporting body for a catalytic reactor is disclosed. In order to reduce thermal stress between the casing tube and the wound metal supporting body of an exhaust gas catalyst, the temperatures of which vary significantly during operation, it has been proposed to provide the ring-type composite of metal strips fastened in a casing tube with slots extending in longitudinal direction. This type of production results in high expenditures. The new process and arrangement of the invention provides that incisions are made directly into the metal strips before the winding or folding of the supporting body, so that a subsequent processing becomes superfluous. The thus produced supporting bodies have a plurality of incisions extending within the ring-type composite which can also prevent the buildup of thermal tensions or stress. The new supporting bodies are used for exhaust gas catalysts of motor vehicles.
