Abstract: WILLIAM A. BARR           A Citizen of the United States Residing at Gibson Island, Maryland KING PIN FOR TRACTOR TRAILER     FIFTH WHEEL COUPLING     Abstract of the Disclosure A king pin for a tractor trailer coupling is disclosed.  The king pin is substantially conventional except that the lower flange thereof, which is presently standardized to have less diameter than the upper part of the king pin, is made predeterminedly larger than the upper part so that it cannot be received in the usual recess at the upper end of the coupler jaw when closed, or when the jaw is opened the flange positively prevents the jaw from closing.  Thus a trailer can never be towed at all by partial seating of the flange of a misaligned king pin in the upper recess of a closed jaw as now can occur with a standardized king pins resulting in unexpected and dangerous separation of the tractor and trailer on the open highway.

Abstract: TITLE EFFICIENT LASER GENERATION  OF SURFACE ACOUSTIC WAVES     INVENTORS Paolo G. Cielo Jean Bussière ABSTRACT OF THE DISCLOSURE        The surface acoustic waves are generated by laser beam that is focussed onto a surface to irradiate it in an arcuate pattern as a par-tial annulus or as a still or moving fringe pattern.  The arcuate pattern may be formed by a transmitting or a reflecting axicon, while the fringe pattern may be formed by splitting the laser beam into two beams and di-recting the two beams to the surface.  In addition, a lens or a frequency shifting device may be placed in the path of one of the split beams to form a circular fringe or a moving fringe, respectively.

Abstract: Abstract A hot melt gun  having a melt body with a melt chamber and a feeding device for feeding a rod of hot melt material in solid form, under the control of an operator, into the melt chamber.  A carriage supports the rod of hot melt material and a clamp member and a trigger are provided to grip the rod and feed it into the hot melt chamber. The improvement in the hot melt gun resides in that the clamp member has two axial pivot pins integral therewith and projecting outwardly from opposite sides thereof with each pin having an arcuate coaxial bearing portion and a chordal flat face.  The carriage has two opposite sides each having one of the coaxial bearing openings to receive the pivot pins.  The bearing openings are defined by substan-tially circular bearing surfaces against which the bearing portions of the pins are supported. Each bearing surface has an assembly opening extending around a minor arc in the surface remote from the rod of hot melt material supported by the carriage.  The width of the assembly openings is slightly larger than the distance between the flat faces of the pivot pins so that, during assembly of the gun, the pivot pins pass through the assembly openings with narrow clearance when the pins are oriented with the flat faces generally parallel to a radius of the bearing openings bisecting the assembly openings, but so that, when the gun is fully assembled, the arc of pivotal movement of the clamp member is restricted and the pivot pins cannot reach an orientation where the flat faces are sufficiently aligned with the assembly openings to permit withdrawal of the pivot pins through the openings.

Abstract: AUTOMATIC RECOVERY SWING SIGN STRUCTURE            Abstract A yieldable highway swing sign is described which swings out of the way when struck by farm equipment or other objects such as wet snow from snow plows.  The sign has a torsion bar which returns the sign to its original position after being struck.  The sign has notches in its hinges to maintain its original position.  The notches resist any displacement forces by providing an inclined plane of 40° which must be overcome before the sign is displaced in an arc pivoting around the torsion bar.  The displacement of the sign is limited to a 90° displacement from the original position by the configuration of the hinges and is helped by the increased torque created by the torsion bar as the sign swings further from its original position.

Abstract: Abstract of the Disclosure Containers formed of a flexible sheet of material capable of being sealed for closing off the interior of the container from the ambient atmosphere.  The sheet material is resistant to tearing and includes an inner surface and an outer surface.  The container comprises a mouth portion in-cluding a peel strip or layer fixedly secured to the inner surface of the material and extending substantially the entire length of the mouth portion, with adjacent portions of the peel strip or layer being in releaseable engagement with each other.  The engagement forms an air-tight interfacial seal at the mouth which is readily openable by peeling the engaging portions of the peel strip or layer from each other to provide ready access to the interior of the container without tearing the sheet material forming the container.  Thus, the container can be readily reclosed by conventional mechanical means, such as folding, tin ties, etc.

Abstract: Abstract of the Disclosure In a synchronization circuit for use in demodulating an input signal carrying a transmission data signal at a symbol rate, a sampling circuit samples the input signal at a predetermined sample rate which may be different from the symbol rate, to produce a sequence of sampled signals.  The sampled signal sequence is interpolated by the use of an interpolator into first and second partial interpolated signals which have different phases from each other.  The first and second partial interpolated signals are processed by a processing circuit to produce timing errors between the first partial interpolated signals and the sampled signal sequence.  The processing circuit controls the phases of the first and second partial interpolated signals with reference to the timing errors so that both of the partial interpolated signals are derived at predetermined points of the sampled signal sequence.  On reception of the transmission data signal of a multi-level divisible into a plurality of bits, the interpolator comprises a plurality of elementary interpolators for interpolating the respective hits to produce fragmentary interpolated signals.  The fragmentary interpolated signals are combined into the interpolated signal sequence.  The elementary interpolators may be controlled by two internal samplers in consideration of the timing errors.
