Abstract: METHOD AND APPARATUS FOR CONTROLLING THE         VELOCITY OF INK DROPS IN AN               INK JET PRINTER         ABSTRACT OF THE DISCLOSURE    In an ink jet printer, drops are generated at a test frequency which is a harmonic of the drop generation rate for printing.  If an error in velocity is detected at the test frequency, a coarse correction velocity is made to bring the correct number of drops within the range of one-half the wavelength at the nth drop location relative to a drop detector.  Drops are then generated at the printing frequency and a fine correction in the velocity is made if a velocity error is detected.

Abstract: ABSTRACT A tobacco-smoke filter comprises a plug of filter material of which a transverse cross section is impervious to the passage of smoke except for a minor proportion of the area of that cross section which forms a smoke-accelerating orifice, the said plug being enclosed by an envelope permitting ingress of air into a region of the plug downstream of the orifice.  The cross section may be impervious because of the presence of a barrier diaphragm of impervious material.  Thus an annular groove may be provided in the plug at the said cross section and may be filled with, or have its walls coated with, an impervious material.  Alternatively the said cross section may be impervious by reason of the closure of interstices in the filter material by the local application of heat thereto.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for vaporization of liquids having a boiling point lower than that of water, comprising a vessel having at least three narrow planar plena, contiguous to each other, so that there is a single metal wall between each adjacent pair of plena.  Gaseous fuel and air are supplied to the first plenum to provide a downflowing flame and hot products of combustion which, at the bottom of the first plenum, pass through the wall into the second plenum, which is filled with water.  The hot gases and water rise rapidly in the second plenum and the water flows over the intervening wall into the third plenum, which is also filled with water, which moves downwardly and back under the wall separating the second and third plena, and again rises in the second plenum.  A vertical array of horizontal pipes is arranged in the third plenum, through which the liquid to be vaporized is flowed.  Means are provided at the base of the first plenum to distribute the flow of hot gases substantially uniformly over the cross-section, to provide more rapid and uniform heat transfer from the hot gases to the liquid.  The hot water flowing downwardly over the pipes in the third plenum transfers heat to the liquid therein, which flows counter-currently, upwardly through the pipes in zig-zag fashion. The cooled products of combustion are vented from the top of the space above the second and third plena to a stack.  An optimum embodiment comprises a symmetrical assembly with duplicate second and third plena on each side of the first plenum.

Abstract: ABSTRACT     A longitudinally elongated settling tank with a converging longitudinal hopper bottom along the length thereof has a longitudinally elongated travelling bridge reciprocating continuously or intermittently through a relatively short stroke between the inlet and outlet ends of the tank from which depends a plurality of longitudinally spaced sludge pick-up heads each sucking sludge from a zone in the bottom of the tank during a present cycle.  Liquid fed into one end of the tank forms a settling pond from which clarified liquid flows over longitudinal weirs at the opposite end of the tank.  In a preferred embodiment a first pick-up head serves the inlet end zone of the tank in which the heavier sludge settles from the pond, a second pick-up head serves the middle zone of the tank while a third pick-up head serves the outlet end zone of the tank.          The first head is evacuated as the bridge advances toward the outlet end of the tank until the head reaches the end of the inlet end zone which it serves whereupon the bridge is retracted and the now advanced second head is evacuated during the retraction to remove lighter sludge from the bottom of the middle zone of the pond.          Then, the first head is again evacuated during the next advance of the bridge to pick up the heavy sludge that has settled in the interim in the bottom of the inlet end zone of the pond.  The bridge is next again retracted and the third suction head is evacuated to remove the lightest sludge at the outlet end zone of the pond.          Thus the heavier sludge is removed twice during two full stroke cycles of the bridge while the lighter sludges are successively removed only once during these two cycles and the length of the stroke is much less than the length of the pond.  Because of the short stroke of the bridge, the tank can be reinforced with internal framework between the paths of the suction heads permitting use of lighter sheet metal for the tank.          A skimmer is automatically lowered into the top of the pond as the bridge advances to sweep oil, scum, and other material floating on the pond into an outlet and is retracted above the pond on the return stroke of the bridge.

Abstract: Abstract of the Disclosure There is disclosed an air motor adapted to rotate and axially shift an arbor having an annular cutter attached thereto.  Within the arbor a plunger is slideably arranged with its leading end bearing against a pointed pilot pin at the center of the cutter.  The plunger is biased forwardly by either a spring cartridge or a piston-cylinder assembly so as to apply a predeter-mined constant or programmable pressure on the pilot pin throughout the entire cutting cycle.  When the cutter penetrates through the under face of the workpiece, the pressure on the plunger is reduced to a very low value so that the slug within the cutter will be ejected at a relatively slow safe velocity.
