Title: Mechanism and method for assembling tapered, nestable containers

Abstract: MECHANISM AND METHOD FOR ASSEMBLING TAPERED, NESTABLE CONTAINERS Apparatus for forming a tapered, nestable leakproof container having a bottom wall integral with front and back panels and side panels and a triangular connecting panel between additional panels extending from the front and back panels and the side panels, wherein the apparatus comprises a die and a tapered mandrel for forcing a blank through the die. The container blank is positioned on a support immediately above the die and held in position by guides on the support. Before the tapered mandrel engages the blank, glue is applied to the outer edges of the side panels of the rear wall of the container at the inner surfaces adjacent the outer edges of side panels connected to the rear panel and at the inner surface adjacent the outer edges of the side panels. The blank is forced into the die by the tapered mandrel. Appropriate pressure rollers resist the entry of the mandrel and move outwardly as the mandrel moves into the die moving the blank into the die. These pressure rollers engage firmly against the outer surfaces of the sections of the blank to which the glue has been applied and provide resilient pressure in order to squeeze and spread the glue and to press the glue into formation. The die is thus not a rigid die, but one which may yield to and follow the tapered form of the mandrel. Additional pressure rollers may be provided for the portions of the die engaging the front and back walls of the blank in order to provide firm guidance for the blank. The blank, after being pushed through the die, drops down and is delivered to the user's conveyor.

Abstract: METHOD FOR CONTROLLING THE OPERATION OF AN           OPTICAL SCANNER                           Abstract An optical scanner in a retail store checkout stand includes a single item detector upstream of the scanner window.  Output signals from the item detector and from symbol recognition logic are used to open and close a shutter in the beam path of the scanner laser.  The shutter is opened and a first time out sequence is started when the beam path is interrupted.  A second, short time out sequence is restarted each time a valid symbol is recognized. A third time out sequence of intermediate length supersedes the first time out sequence when the beam path is cleared.  The laser shutter is closed and the symbol is transferred to a terminal or controller upon the completion of and active time out sequence or upon recognition of a predetermined number of identical symbols, whichever comes first.

Abstract: IMPROVED GAS SEPARATION PROCESS               Abstract of the Disclosure The separation of gas mixtures in commercial sized adsorption systems is carried out with a carefully limited difference in loading of the adsorbed component on the bed between the start and the end of the desorption step.          Under such conditions, each succeeding adsorption step will be carried out so that an adsorption/heating front is caused to advance sufficiently ahead of a slower moving cooling front that thus serves to cool only the feed end of the bed  to the inlet gas mixture temperature.  The heat of adsorption is thereby retained in the  bed  between these two fronts at a temperature tolerable  to the gas mixture and to the  adsorption bed and is available for the follow-ing desorption step.

Abstract: Abstract of the Disclosure:     A quality measure of a signal received at a receiver of a two-dimensional linear modulation data communication system, is measured by using a phase controlled baseband signal (yk.exp(j?k)) obtained from the received signal and a reproduced data signal (?k) derived from the phase controlled baseband signal.  That portion of the quality measure which is introduced into the received signal in a transmission channel for the received signal, is measured by estimating a data signal component (?k) which includes intercode interference, by subtracting the data signal component from the phase controlled baseband signal to produce a difference signal of a phase difference relative to the reproduced data signal, by giving the phase difference to the difference signal to produce a phase adjusted signal, and by calculating a mean square of an inphase component of the phase adjusted signal.   Portions of the quality measure which are related to a carrier phase jitter component and a carrier frequency offset component, are measured also by the use of the phase controlled baseband signal and the reproduced data signal.  It is possible to carry out the method by a signal processor.
