The method serves for the production of a wire strip (1) comprising a plurality of wires (2) arranged parallel to each other. For this purpose a metal strip is first pre-notched either on one side or both sides for the formation of the wires (2), whereby wires (2) are generated which are still connected to webs (3). To transform the webs (3) subsequently into thin, easy to separate and, when separated, smooth and burr-free separation webs forming separation areas, the wire strip (1) is subjected to a milling process during which each web (3) is subjected to a multiple bending strain along the longitudinal axis thereof in such a way that incipient cracks form, due to fatigue fracture, in the area of the webs (3), and thereby the separation web is created.

Diffusion bonding techniques are extended to the simultaneous bonding of an array of multilevel piece parts. The problems of uneven expansion and contraction of different levels of different piece parts in the array are obviated by positioning each level of the array within a frame. The stack of frames is pinned in one corner. The opposite corner of the array has a slot at a 45° angle with respect to the x and y axes of the array. The slot engages a pin and allows the entire array to expand and contract along the slot in a manner to maintain the registration of features between respective levels of each piece part.

The connecting strip for the manufacture of electric components intended to be used with flow soldering; this connecting strip acts during the entire manufacturing cycle as a support for the base elements of the components and as a joining plane for the molding of the coating resin, the notches punched out in the strip thus limiting the output electrodes of the components as well as the electric connections inside the coating.

A channel-shaped trim having a longitudinally extending opening for embracing and clamping an edge flange of a support member comprising a core member having a large number of disconnected channel-shaped core pieces constructed with at least two strip-shaped elements and connecting portions which are positioned symmetrically with respect to both side end portions of the elements so as to define and surround all sides of at least one slot between the elements and the connecting portions. In addition, the trim includes a covering member enclosing the core member and charged between the adjacent core pieces and in slots which are formed in the core pieces.

A pre-mixed adhesive composition comprised of a vinyl acetate polymer emulsion including a cross-linking catalyst and a cross-linking inhibitor providing a good cured water resistant Type II bond and extended shelf life so that the adhesive composition will not gel over an extended period of time and will therefore be usable for direct gluing application to semi-porous and porous substrates.
