Abstract: In the case of a process for the production of homogeneous mixtures of alloys, in particular of intermetallic phases of at least two alloy components, by the melting of raw materials in an inductively heated cold wall furnace the following processing steps are applied: a) in a first processing step, the alloy components are melted into blocks with predetermined alloy composition according to the amount, and b) in a subsequent processing step, at least one of the blocks from the first processing step is melted down in an inductively heated cold wall furnace arrangement (60) where the melt is stirred by the electromagnetic field energy fed into the melt in such a manner that its alloy components are mixed thoroughly in such a manner that the melt (55) obtains a homogeneous material composition over its entire volume. Optionally, the first processing step can be carried out in an inductively heated cold wall furnace arrangement which is charged with chargeable raw materials, or the first processing step can be carried out by a vacuum arc remelting process in a cold wall furnace arrangement which is charged with preformed consumable electrodes.

Abstract: A latent image structure of a highly secure nature in which two latent image are superimposed. Each of the superimposed latent images is viewable from a different line of sight. Relief elements define, for each latent image, portions of respective linear relief structures providing an image and a background which cooperate to generate the latent image. Relief elements are only provided at locations where the linear relief structures of the first and second latent images intersect. The resultant latent image structure, when viewed normally, has the advantage of a relatively flat appearance, making it difficult to discern the presence either of the superimposed latent images.

Abstract: A method for tracking a locally generated spread spectrum signal sequence includes the step of correcting the spread spectrum signal sequences with respect to the synchronization time in an early/late interval. The correlation responses are subtracted from one another and the clock of the locally generated spread spectrum signal sequence is controlled as a function of the subtraction. Correlations are performed through the use of at least two hierarchically staggered closed-loop controls having different early/late intervals. The early interval of the one closed-loop control having a small early/late interval must not become earlier than the early interval of the other closed-loop control system having a next-larger early/late interval. Furthermore, the late intervals of the one closed-loop control system having a small early/late interval must not become later than the late interval of the other closed-loop control system having a next-larger early/late interval. A configuration for tracking a spread spectrum signal sequence is also provided.

Abstract: A flap mechanism includes elements for compensating tolerances and shrinkage of the flap. The compensating elements include a flap edge which is applied to the flap by assembly injection molding after the flap has cooled, thereby decreasing any gap produced between the flap and a surrounding frame by shrinkage of the flap. In addition the flap has a flap shaft which can be journaled in the frame through a conical region on the shaft such that axial shrinkage of the shaft to produce a mounting which is free of play. This construction makes it unnecessary to use additional sealing elements at the mounting locations of the flap, and the flap is also prevented from vibrating in its mounting which, in a worst case scenario, could lead to destruction of the flap.
