Abstract: Abstract of the Disclosure A metal-strip pickling apparatus has feed means including upstream and downstream bridle-roller pairs for longitudinally displacing the strip under longitudinal tension along a straight transport path from the upstream bridle-roller pair to the downstream bridle-roller pair. A housing longitudinally traversed by the strip is subdivided longitudinally by a succession of transverse partitions into a longitudinal succession of compartments each having a respective treatment bath, normally of acid. Each partition has a rigid lower partition half having an upper edge and an upper partition half having a lower edge portion elastically engaging the upper face of the strip moving along the path. the upper edges all are longitudinally aligned and touch the lower face of the strip moving along the path. The acid baths have liquid levels above the upper edges of the respective lower partition halves. The lower portions of the upper partition halves seal tightly with the strip and respective lower partition halves. Thus liquid from one bath cannot pass between the respective partition halves into the next compartment. The use of a straight transport path through the apparatus means that strip tension is irrelevant.

Abstract: Abstract In a demodulator for use in deriving demodulated signals from a mod-ulated signal subjected to k-by-k quadrature amplitude-and-phase modulation where k is equal to 2N and N is an integer greater than unity, first and second detection signals, each having k-levels, are derived from the modulated signal by a coherent detecting circuit and processed by first and second processing circuits.  Each of the first and the second processing circuits is implemented by a combination of (N-1) full-wave rectifier(s) and (N+2) binary detectors to produce each set of binary signals and each additional binary signal divis-ible into a pair of partial bit signals.  Alternatively, each processing circuit is implemented by a combination of N full-wave rectifiers and first through (N+1)-th binary detectors.  The first through the N-th detectors detect each set while the (N+1)-th detector, each additional binary signal. Anyway, each set serves to produce the demodulated signals while each addit-ional binary signal, an AGC signal and an APC signal.

Abstract: Abstract of the Disclosure A machine for forming a slug of edgewise supported flat articles. The machine includes a table above which the articles of the slug are accumulated. Paired conveyor belt means advance the articles in shingle fashion past an edge of the table. One of the belt means has a portion parallel to and at substantially the level of the table for rapidly advancing lower edges of the articles away from the other of the belt means and onto the table. An upper backstop supports the articles on the table and on said belt portion. The articles are urged toward the backstop means to form the slug. The upper backstop is advanced from said edge of the table as the slug of articles forms on the table. Control of the slug is transferred from the upper backstop to an auxiliary backstop. Upright fingers are advanced into engagement with a last article in the slug so that the slug is held between the fingers and the auxiliary backstop. The fingers and the auxiliary backstop are advanced in unison to advance the stack to a discharge station.     This invention relates to a machine for accumulating flat articles such as flattened cartons in a stack. An object of this invention is to provide a machine which feeds articles to a stack in which the articles are supported on edge on a table, accumulates a selected number of articles in the stack, and advances the stack as a unit to discharge the stack.
