In alternative embodiments, the flitch mounting surface is positioned adjacent the staylog mounting surface, and the staylog, or just the staylog mounting surface, is oriented to position the veneer-producing zone in a parallel relation with the veneer-slicing knife.

Abstract: Parallelism between of two opposite surfaces of a workpiece is assured by referencing off of three features on the edge(s) of the workpiece, the three edge features establishing a single, unique plane within the workpiece for referencing the machining operations performed on the two opposite surfaces of the workpiece. The workpiece is held by corresponding two sets of three fixture points, above the surface of two corresponding fixtures, or of one compound fixture, while machining the two opposite surfaces. In this manner, problems associated with referencing off of the first machined surface, to machine the second surface, are completely avoided. This is particularly useful when machining the opposite faces of an automatic transmission valve body. The one set of fixture points is identical to the other set of fixture points, to ensure accurate positioning of the workpiece from fixture-to-fixture (or from set of fixture points to set of fixture points, in a compound fixture).

Abstract: A process for generating an entertainment audio signal interrupted by advertising audio signals in which pilot signals associated with the advertising audio signals cause switching between the entertainment audio signals and the advertising audio signals makes it possible to broadcast different radio programs of the desired acoustic quality in a shop by means of a carrier frequency. To this end, a high-frequency control signal is generated from advertising audio signals and pilot signals which precede or follow the advertising audio signals. The control signal and preferably the entertainment audio signal are modulated to a high-frequency carrier signal, possibly with several channels, for the separate recovery of the signals. The modulated carrier signal is transmitted, the transmitted carrier signal is demodulated and, if necessary, the signals are separated from each other. The pilot signals of the transmitted control signals are monitored for the presence of fading or flashback conditions.
