Abstract: ABSTRACT OF THE DISCLOSURE         A thin-walled large diameter spiral plastic tube with interlocking helical seams made from a strip of polyethylene material.  The strip of plastic has a thin configuration with edge constructions providing a bead formation along one edge and a groove formation along the opposite edge, which can enable an interlocked helical seam, in the spiral tube.  The strip is fed into a special spiral pipe making machine for plastics which winds and interlocks the edges of the strip.  Such tubing is used for ducts and pipes and, filled with expanded polystyrene beads can be used very advantageously as flotation devices. The plastic used in the strips is polyethylene, including medium and high density polyethylenes with high molecular weight (HMW).

Title: Method of and apparatus for continuously casting  metals

Abstract: METHOD OF AND APPARATUS FOR CONTINUOUSLY             CASTING METALS            ABSTRACT OF THE DISCLOSURE          Molten metal is continuously teemed from a ladle into a tundish.  The latter feeds a continuous stream of the molten metal to a cooled mold having opposite open ends connected by a casting passage. The molten metal enters the mold at one end and partially solidifies in the casting passage to form a continuously cast strand which is withdrawn from the mold at its other end.  The strand initially consists of a thin shell of solidified metal, and a molten core which is confined by the shell.  Upon leaving the mold, the strand is conveyed through a bath of molten metal.  The metal of the bath has a lower melting point than, and a specific gravity comparable to that of, the metal being cast.  The bath functions to cool the strand uniformly so that the quality of the strand is maintained.  The bath further counteracts the tendency of the molten core to cause bulging of the solidified shell which also serves to enhance the quality of the strand.  Additional enhancement of the quality of the strand is obtained by virtue of the fact that the bath protects the strand from the atmosphere.  The strand leaves the bath after the molten core has solidified and is then cut into sections for further processing.

Abstract: OPTICAL LOGIC ARRANGEMENT WITH SELF   ELECTRO-OPTICAL EFFECT DEVICES Abstract An arrangement for performing an optical logic operation.  The optical logic arrangement comprises a plurality of reflection holograms positioned in a two-dimensional array for optically interconnecting a similar pluarlity of optically nonlinear self electro-optic effect devices also positioned in a two-dimensional array.  Each self electro-optic effect device is responsive to control light beams received on either side of the device array for emitting an output light beam that is a nonlinear function of the control light beams.  Accordingly, each self electro-optic effect device can regenerate light beams and perform an optical logic function.  In response to an output light beam from a specified self electro-optic effect logic element, the associated reflection hologram originates an individual control light beam to one or more designated self electro-optic effect logic elements in the logic array.  Consequently, the self electro-optic effect logic elements may be optically interconnected to perform a combination of sequential and combinational logic operations including those, for example, of an optical digital processor.

Abstract: ABSTRACT OF THE DISCLOSURE      A road surface is scanned with a laser beam in a direction transverse to the road surface to pick up the scanning locus of the laser beam on the road surface in a direction inclined to a beam scanning surface so as to obtain transverse profile data.  The laser light reflected from the road surface is received in a direction inclined to the beam scanning surface for obtaining crack data.          The distances to the road at three points in the longitudinal direction of a measuring car are measured.      The running distance of the car is measured and the measured distance data are recorded in a recording device together with crack data, transverse profile data and longitudinal profile data.

Abstract: ABSTRACT OF THE DISCLOSURE        A measuring device for determining the pressure zone width and/or surface pressure between a web roll for a web and a further roll of a winding apparatus includes at least one reflex sensor emitting a radiation towards the web roll and receiving radiation reflected from the web roll.  The reflex sensor is provided with a source emitting the radiation towards the web roll and a receiver which picks up beams reflected from the web roll.  Source and receiver are embedded within the peripheral area of the further roll and are arranged adjacent to each other.  During winding of the web, the reception of the radiation is interrupted when the web roll covers the source and/or the receiver.  This interruption of the reception is a measure for the pressure zone width and in connection with other variables and constants for the roll firmness.

Abstract: Abstract:           An electromagnetic contactor is so constructed that the electromagnetic device and the fixed contact are fix-edly fitted into a casing which is divisible in the direc-tion along the moving direction of a polar contact.  A bottom casing with a screw mounting hole is fitted in the outer peripheral portion at the lower end of the casing. The rigidity of the casing as a whole is thereby enhanced, and at the same time the working characteristics can be prevented from being changed when the screw is mounted. Furthermore, the positioning accuracy of the electromagnetic device relative to the fixed contact is determined only by the dimensional accuracy of the casing and the electromag-netic device, and by the position accuracy of the fixed contact.  The contact pressure is thus of improved stability.

Abstract: ABSTRACT   A combustion method and burner nozzle system having a DeNOx Stabilizer concentrically secured within a burner nozzle such that the fuel stream is separated into an outer fuel-rich stream and an inner fuel-lean stream. The outer fuel-rich stream passes around the exterior of the DeNOx Stabilizer where its flow area is increased thereby decreasing its velocity before it is discharged from the burner nozzle. Concurrently, the inner fuel-lean stream passes through the DeNOx Stabilizer where its flow area is reduced thereby increasing its velocity before this stream is discharged from the burner nozzle central to the slower fuel-rich stream. Mixing members interior of the burner nozzle further mix the fuel-rich stream before exiting the nozzle.

Abstract: POSTAGE METER WITH NON-DOLLAR AMOUNT INDICIA     Abstract of the Disclosure A postage meter which imprints non-dollar amount indicia representative of postage value determining information.  The meter receives postage value determining information, such as mail piece weight, associated with particular mail pieces; computes the corresponding postage; imprints the particular envelope with the postage value determining information; and accounts for the postage thus expended.  Because the range of postage value determining information is small compared the possible range of postage setting information the meter to print is quicker and easier. In one embodiment the meter also prints a validating indicia which assures that the rates used to compute the postage value are valid.  In another embodiment the postage value determining information includes information which characterizes a batch of mail, for example as being entitled to a pre-sort discount.
