Abstract: A method and apparatus for the temperature regulation of components such as semiconductor circuits, printed circuit boards and the like. The components are conveyed on carriers through an inlet slot into a temperature regulating housing provided with temperature regulating members and are convey out through an outlet slot opposite the inlet slot. In the housing, the carriers are loaded on a magazine provided with adjacently arranged holders. After the first holder is loaded in the starting position, the magazine is displaced progressively in one direction into successive positions in which the remaining holders of the magazine are loaded one after the other. Once all the holders are loaded, the magazine is filled and in an end position. Thereupon the magazine is displaced back to its starting position in a fast reverse run in the opposite direction.

Abstract: The invention relates to an ultrasound welding process and an ultrasound welding device for securing at least two wire ends located one above the other to contact regions of electrical parts, particularly to contact regions of laminations of commutators for rotating electrical machines or motors, having a sonotrode and having a device for introducing a contact pressure force. It is contemplated that all the wire ends (16, 18) to be secured to at least one contact region (14) are pressed against the contact region (14) by means of the contact pressure force (F), and at the same time the sonotrode (28) sets the lower wire end (16) into oscillation transversely to the contact pressure force (F).

Abstract: The fastener, which can be arc-welded to a component, is in the form of a resilient sleeve (1) and has a longitudinal slit (2). In a preferred embodiment both its end faces (3) are identical in construction, in order to simplify previous sorting to ensure accurate positioning in the welding assembly apparatus, and provided with a thread-shaped internal bore (4). The welding assembly apparatus for welding on elongate fasteners is provided with a feed channel and an axially displaceable holder for the fasteners. Instead of a slitted collet chuck, the axially displaceable holder (5) is in the form of a rigid tube in which are retained the fasteners in the form of resilient sleeves (1). The arrangement for attaching an assembly part to the fastener has an assembly part (21) which may be set on the fastener in a frictionally- and positively-engaging manner. The assembly part (21) can have in its bore (27) a projection (28) for engaging behind holder (23) mounted on the external wall of the fastener (20).
