Abstract: An inductive component includes a closed magnetic core and a first conductor that runs at least twice through the interior of magnetic core. The first conductor is a solid conductor that includes several U-shaped pre-bent parts that are tightly connected to one another. The U-shaped pre-bent parts may be each be flat conductors. Flat sections of the flat conductors may run in planes oriented transversely to one another.

Abstract: A package for film cartridges in the form of a canister which consists of the following parts:a) n hollow cylinders,b) 2 end caps andc) n-1 connecting elements,wherein n means an integer, all the parts have the same cross-section, the hollow cylinder is taller than both the end caps and the connecting elements, the hollow cylinder is positively connected, on the one hand, with the end caps and, on the other hand, with the connecting elements, where these are present, and the external diameter of the end caps and the connecting elements is no smaller than the diameter of the hollow cylinder, is stackable and may be produced rapidly and with economies of material.

Abstract: A package for photographic films wound into cartridges, where the package takes the form of a cylindrical tub consisting of two identical tub halves and a support ring over which the openings of the tub halves are pushed, whereby the support ring has a small height in comparison with the tub halves and tub halves and support ring are so designed that they are held together by snap-action connections, can be manufactured more quickly and with less material consumption, is capable of being stacked and also exhibits the advantages of known packages.

Abstract: In an injection moulding tool for the production of a magnetic tape cassette casing constructed, in part, in two layers the apparatus has a fixed core (1a) provided, on the rim, with a projection (5) which provides a sealing strip relative to the moving core (2a). After the injection moulding process into the first mould cavity (4), the moving core (2a) is moved axially downwards by about half the wall thickness, whereupon the second mould cavity (3, 3') is filled by injection through a second needle shut-off nozzle (FIG. 1b).

Abstract: An injection mould having several gating points (3) which are all supplied with moulding material at the same time has a hot runner manifold (2) situated in a composite body. The composite body is composed of several plates (9,11,12,13,9') in which both the system of hot runners (2) and the tubular heating elements (10) required for heating are formed, starting from the surfaces of separation (F1, F2, F3, F4), whereupon the individual surfaces are joined together by diffusion welding after they have been pretreated as required (FIG. 2).

Abstract: An injection moulding tool with optimum temperature distribution as the result of an improved tempering duct system is obtained if the tool inserts (10, 11) are each made up of two or more plates, tempering ducts (12, 12', 12") are worked in from the external faces (F1, F2, F3), on which the parts are subsequently joined by the diffusion welding method. An injection moulding tool for VHS reel hubs produced by this method produces moulds for injection moulding with substantially reduced wobble and a reduced cycle time.
