Abstract: Abstract of the Disclosure An improved machine and method for stiffening a selected portion of a sheet-like member generally flattens that portion, next deposits on a chill plate matrix an adhesive hot melt deposit of mostly uniform thickness except for a margin of added thickness for slower hardening, and then causes the matrix with impact to press all of the adhesive, while the added thickness margin is still softer than the uniform adhesive thickness, against the flattened portion of the member, thus transferring the adhesive to that portion, the added thickness margin being exuded laterally and hence taperingly reduced to provide diminishing stiffness toward an edge merging with the member.           The machine and method have particular advantage in stiffening a toe portion of a shoe upper, rendering the instep margin of the vamp or a toe piece free of irregularity, and assuring ultimate confort for wearing in an assembled shoe.

Abstract: Abstract Of The Disclosure A connector assembly for a coaxial cable having an annularly corrugated outer conductor has a first unitary clamping member which fits over the end of the coaxial cable and forms an inwardly extending bead at one end thereof for meshing with the last valley in the corrugated outer conductor, thereby locking the clamping member to the cable in the axial direction. One side of the bead also forms a first conically beveled clamping surface for engaging the outer sur-face of the last crest in the corrugated outer conductor. When the clamping member is advanced over the cable during installation of the connector assembly, the bead cams a plurality of resilient segments in the beaded end of the clamping member outwardly to clear the crest of the corrugated outer conductor. The resilient segments are formed by a plurality of longitudinal slits, and the camming of these segments outwardly during installation of the clamping member permits the bead to pass over the crest of the corrugated outer conductor before it snaps into its locked position. A second conically beveled clamping surface, preferably formed as an integral part of the main body member of the connector, engages the inner surface of the last crest in the corrugated outer conductor of the cable. Telescoping sleeves formed as integral parts of the clamping member and the body member are provided with cooperating threaded surfaces which serve to draw and hold the two clamping surfaces together against opposite surfaces of the outer conductor of the cable. An outwardly projecting bead on the clamping member minimizes the area of frictional engagement between the unthreaded surfaces of the two members to avoid rotation of the clamping member around the cable. The corrugated outer conductor is preferably cut off at substantially the apex of one of the crests of the corrugations so as to form an annular flared end on the outer conductor. An O-ring is seated in one of the valleys of the outer conductor and bears against the inner surface of the clamping member to provide a moisture seal between the outer conductor and the clamping member.

Abstract: ABSTRACT OF THE DISCLOSURE             A pumping system for dispensing controlled and variable amounts of fluids in predetermined quantities includes a pump piston which moves axially in a pump chamber.  The piston is reciprocated by a drive load nut cooperating with a non-rotatable lead screw attached to the piston.  The piston is sealed to the pump chamber by a seal element whose distance from the lead nut is fixed regardless of the position of the piston, thus protecting the seal.  The rotatably driven lead nut includes a hollow driven shaft, containing lubricant, so that the lead screw is lubricated as it travels into shaft of the lead nut. The motor for the system is a pulse operated reversible stepping motor enabling accurate output from the pump, for example, between .01 ml/min to 9.99 ml/min as controlled by the stepping motor. One motor may drive two pumps for continuous controlled pumping system.  If desired a flush mechanism may be used to rinse the piston of any pumped material which adheres to the surface.

Abstract: ABSTRACT OF THE DISCLOSURE    A tile stacking machine wherein each tile is tilted while being conveyed at high speed and supported by its lower edge.  The tiles are then transferred to a set of speed reducing belts to travel on edge.  In most instances they are then transferred to at least one further set of speed reducing belts so as to crowd the tiles into a stack.  One of the features of tilting the tiles while being conveyed edgeways, is that tilting is achieved by slowing the leading edge as it is lifted, thereby reducing tile speed even before it enters the speed reducing belts.

Abstract: ABSTRACT OF THE DISCLOSURE        An apparatus comprises a pair of rolls having a gap therebetween for the passage of sheet material to be treated and rotatable in opposite directions.  There is also provided a means for generating a magnetic field, with the lines of force passing along the axes of the rolls and across the gap formed therebetween.  The rolls, therefore, serve as opposite poles of magnetic system which enables the ferromagnetic powder to be retained on the surfaces of said rolls under the effect of the magnetic field.  Mounted underneath a bottom roll is a net with a mesh size slightly less than a minimum permissible size of the powder grains.  The net is disposed within the zone of the magnetic field of said magnetic system.  The apparatus desirably includes a switch adapted to discontinue the action of magnetic field, whereupon the powder pours down on the net and through it if unsuitable for further use.  Upon subsequent generation of the magnetic field, the powder is lifted from the net and onto the bottom roll wherefrom it is further  transferred onto the top roll during rotation of the rolls.  The action of magnetic field is discontinued after treating a prescribed amount of sheet material.  The magnetic field is initiated prior to feeding a sheet material into the gap between the rolls.

Abstract: ELECTRONIC MUSICAL INSTRUMENT USING    INTEGRATED CIRCUIT COMPONENTS            Abstract of the Disclosure The embodiment of the invention disclosed herein is directed to an electronic musical instrument of the keyboard type wherein the audio frequency signal information is derived from a multi-frequency generator formed by an electronic oscillator and a plurality of divider circuits, and wherein programmable divider circuits are associated with the various keys of the keyboard to generate associated tone signal information.  The programmable divider circuits are formed on a large scale integrated circuit chip and enable alteration of the numerical divisor so that different tone signals can be obtained from the same electronic circuitry thereby enabling the same type of LSI chip to be used for many different circuit configurations.  The LSI chip also provides a scanning circuit that scans an X-Y matrix switching arrangement to determine which one of a plurality of key switches is closed.  The inte-grated circuit unit has a plurality of such programmable divisors arranged to be operated from the same frequency, preferably there being four programmable divisors to obtain a multitude of output audio signal frequencies.  Actuation of a key switch, chord button switch, or foot pedal will enable gate circuit components to cause a signal transfer from a matrix array to a read-only-memory circuit, which, in turn, enables selected ones of the programmable divisors for devel-oping the desired audio signal frequencies.
