Abstract: ABSTRACT OF THE DISCLOSURE        Method and apparatus for shaping ends of tubes which are to be welded to a curved convex or concave surface of a further body.  The tube contacts said curved surface so that a notional line in the profile end face of the tube corresponds to a theoretical line of contact for fitting the end face to said curved surface in substantially comple-mentary relationship and at the predetermined angular relationship.          A bevel surface extends between the profile end face of the tube and its outer peripheral surface.

Abstract: FAN FOLD FORM STACKER     ABSTRACT OF THE DISCLOSURE         Apparatus for stacking fan-folded paper including an oscillating chute through which paper received by the stacker from a printer passes toward a pedestal on which the paper is to be stacked.  The stacker receives line strobe signals from the printer indicative of the rate at which paper is fed by the printer to the stacker.  The line strobe signals control the rate of oscillation of the chute between two extreme positions.          The distance between the two positions defines the oscillation stroke which is determined by means of a manually-operable selector to be a function of the form length of the paper to be stacked.  The paper is stacked on a pedestal which is incre-mentally movable between top and bottom positions.  A stack sensor is provided which senses the top of the stack and causes the pedestal to move toward the bottom position so as to main-tain the distance between the chute and the top of the stack relatively constant.

Abstract: ABSTRACT OF THE DISCLOSURE      A package and a method and apparatus for producing same are set forth.  The package preferably is made of two single-faced corrugated sheets having cohesive corrugated surfaces.  A lower sheet has side walls bent upwardly at edge portions thereof and flanges bent outwardly from the upper edges of the walls.  An upper sheet bridges an object to be packaged located on the main portion of the lower sheet between the side walls, and has edge portions adhered to the flanges of the lower sheet.  The ends of the two sheets are pressed to cause them to adhere together with the side walls simultaneously being folded outwardly at the centers and adhered to themselves.  In the machine and method for producing the package, a first web has side walls bent upwardly and flanges outward by suitable folding rails as the web is moved longitudinally in a horizontal direction.  After the object is added, a second web is brought downwardly near the first web with the side edges of the second web and the flanges of the lower web pressed together.  The trailing end of one package and the leading end of another package are then pressed together and severed along a central line to complete the operation.

Abstract: RUN LENGTH ENCODING AND DECODING METHODS AND MEANS            ABSTRACT OF THE DISCLOSURE           Black and white run length encoding means first convert a binary video input signal having a raster scan format into binary black and white run length message codes which are preselected so that the initial or lead bit of each of those codes is at a given logic level.  Ternary encoding means convert the binary message codes into a series of ternary black and white run length message codes which have distinctive amplitude transitions at any intra-scan line code boundaries, and a modulator then converts the ternary codes into a frequency and phase modulated passband signal.  To recover the video signal from the passband signal, the process is reversed.

Abstract: ABSTRACT OF THE DISCLOSURE           A smoke detector operating on the reflected light principle, in which the detector housing components are designed to provide recesses in which the light and photo-cell assemblies are retained, with a slot disposed between the light and photo-cell recesses through which ambient air is drawn into a chamber illuminated by the light source and viewed by the photo-cell.  When smoke is present in the incoming ambient air, it diffuses throughout the chamber to provide a large volume of illuminated smoke for viewing by the photo-cell thereby giving a fast response to the presence of a small concentration of smoke in the ambient air.         The provision of the smoke inlet slot between the light and photo-cell recesses also prevents the accumulation of dust and lint therebetween which could cause a false alarm.
