Abstract: A TRANSFORM MODULATION RECEIVER          Abstract The receiver receives a transmitted signal of which the modulation is one trigonometric transform function of a desired information signal.  The desired signal is recovered by first deriving the Hilbert transform of the sine transform, and multiplying it by the signum of the derivative of the original audio signal to obtain the cosine transform.  The sine and cosine transforms are then decoded to obtain the original audio signal.

Abstract: ABSTRACT OF THE DISCLOSURE:         Adjustable staircase having a pair of stringers each provided with a pair of pantographs, disposed one above the other, identical in overall length and having diagonal levers also of equal length, which levers are pivoted at their center and end points.  The ends of the pantographs are mounted to connectors that are intended to be fixed to the two different levels that are to be joined.   This mounting is such that the ends of the two pantographs,at each level, can pivot about axes that lie in horizontal planes so that if the levels to be connected are moved away or toward one another, cor-responding pivot points on the two pantographs move together in parallel horizontal pivot points planes. The treads of the staircase are fixed to the pantographs by means of supports each of which has a tread portion which is secured to one edge of one tread and a pantograph portion which is pivotally connected to corresponding pivot points lying in the same horizontal plane.  Each pantograph is enclosed in a casing having open ends through which the connectors extend as well as further openings for the tread connectors.

Abstract: AIR SWEEP DEFROSTER     ABSTRACT OF THE DISCLOSURE     A defrost/defog air supply system for issuing a sweeping Jet of Air upon a windshield or other surface to be defrosted or defogged comprises a fluidic oscillator having a power nozzle coupled to receive the defrost/defog air and an outlet for issuing a sweeping stream of defrost/defog air onto the surface.          The fluidic oscillator is short in length (in the preferred embodiment the distance from the power nozzle to the end of the outlet is less than twice the width of the power nozzle) and has a pair of control ports immediately adjacent the downstream side of the power nozzle of the fluidic and a continuous inertance loop interconnecting the control ports with the continuous inertance loop being of a length and cross-section such as to maintain the frequency of oscillation below about 12Hz to thereby avoid mixing with ambient air prior to impingement upon the surface to be defrost.  The downstream edges of the control ports are set back to permit ambient air to enter the control port when the defroat/defog air issuing from the nozzle is at the opposite sides.  Flow straighteners are provided upstream of the power nozzle and just as the air exits from the manifold or supply to assure uniform and symmetrical flow velocity profile in the power nozzle.  Sweep angle enhancers are provided at the outlet so that very short diverging sidewalls reduce the amount of underdash space required.  The continuous inertance loop is shaped and packaged so as to provide a form factor which likewise reduces the amount of underdash volumetric space occupied by the defrost nozzle.  Since the fluidic is more sensitive to the inertance cross-sectional area than the length, care is taken to assure that there is no abrupt changes in cross-section or cross-sectional area of the inertance.

Abstract: ABSTRACT OF THE DISCLOSURE        A heavy-auty shipping container for flowable bulk materials   comprises   an   outer   sleeve   of   multi-wall corrugated  fibreboard extending vertically  from a bottom edge to a top edge thereof and having a polygonal cross section made of plurality of  sidewall panels.   An inner sleeve which is substantally co-axial with the out sleeve has  a  cylindrical  cross  section  and  is  also  made  of muiti-wall corrugated fibreboard.  A multiplicity of false scores is formed on the inner surface of the inner sleeve upon its being bent into a cylindrical shape.  The inner sleeve contacts the outer sleeve along the center of each side  panel.   The  upper  edge  of  the  inner  sleeve  is initially  positioned  above  the  upper  edge  of  the  outer sleeve by a thickness which is less than the thickness of a bottom support pad positioned under  the  lower  edge of the inner sleeve.  With one container stacked on another, the  inner  sleeve  of  the  lower  container  is pushed downwardly to deform the outer periphery of the bottom pad and bring the upper edges of  the inner and outer  sleeve into coplaner positions  in their  post-loading condition. In this way, both the inner and outer sleeve contribute to the column strength of the container.

Abstract: Attorney's Docket No. 7723 INVENTOR:   WALTER REIST          INVENTION:  APPARATUS FOR PICKING-UP AND FURTHER TRANSPORTING             FOLDED PRINTED PRODUCTS, ESPECIALLY SIGNATURES OR SHEETS, FROM A CONVEYING DEVICE                 ABSTRACT OF THE DISCLOSURE       Intermediate or end products comprising a plurality of interstuffed and overlapping folded printed signatures or sheets are straddlingly fed or conveyed by a plurality of collating conveyors  of a circulatingly driven  collating cylinder or drum to a product transfer location or pick-up region.  At the product pick-up region the intermediate or end products are picked-up or taken-over by a product withdrawal conveyor or device.  The product withdrawal conveyor comprises holding or gripping mechanisms which are mounted in spaced relationship on a traction member.  These holding mechanisms comprise pivotable clamping mechanisms which are laterally pivotable into a location between the halves or portions of the folded products.   These halves or portions are raised or separated from each other.  These clamping mechanisms press and thus  clamp the  intermediate or end products  against a counter-element.  A complete closure of the intermediate or end products is thus prevented by the clamping mechanisms inserted between the product halves or portions.  The product halves or portions are spread apart by pivoting the clamping mechanisms together with the counter-elements about a pivot axis. This product spreading action allows transfer of the intermediate or end products while in an open condition to a further collating cylinder or similar apparatus.     WWK:05:am((mlh)(las)):yncl

Abstract: ABSTRACT OF THE DISCLOSURE    A two-part binding system includes one or more bifurcated posts integrally extending from a clamping strip or member.  The posts are inserted into one or more apertures in a stack of punched paper or other material and a second clamping strip having one or more integral or separate latching buttons inserted over and around the posts.  Each button includes one or a pair of toothed pawls integrally hinged to a cross bar extending across a button aperture.  The posts contain a series of transverse ratchets facing each other.  As the second strip and its integral or snap-in latching button is manually pressed over the posts toward the first clamping strip, the teeth of the pawl teeth ratchet successively into the posts toward the base of the posts until the stack of paper is firmly grasped and the teeth mesh with a final transverse ratchet.  At this position, the strips are bowed putting the edges of the stacked sheets in compression.  A spine is also disclosed which has a series of parallel spaced score lines, and is bent around the edges of both clamping strips and firmly adhered to the strips.  A simple tool to unlock the pawls is also disclosed.  This allows substitute pages to be inserted into the stack and the same clamping strips to be manually reconnected.
