Abstract: ABSTRACT OF THE DISCLOSURE     A hydraulic seal for an electrostatic spray coating gun for applying coating materials which have high to moderately high electrical conductivity is disclosed.  The gun has an improved high voltage electrical system, improved hydraulic seals, and is adaptable to apply porcelain enamel coatings in slurry form.          An electrode is positioned forward of a flat-fan spray nozzle and is displaced from the axis of the spray by means of an extension assembly which can be angularly displaced about the axis of the spray.  The gun further incorporates the improved packingless bellows sealing between an opening into the coating conduit in the barrel of the gun and a control rod for a needle valve in the conduit.          Novel static seals allow the use of a bellows in the form of a non-machined extruded fluorinated hydrocarbon commonly known as TFE*Teflon.  The packingless seals, properly designed flow passages, the position of the charging electrode, and wear resistant material at the nozzle tip and needle valve allow the gun to be used not only for the electrostatic spraying of the common electrically conductive coating materials, but also for abrasive coating materials, such as glazes, in slurry form.

Abstract: METHOD AND APPARATUS FOR CLEANING CARPETS AND SURFACES USING CLEANING FLUID                ABSTRACT OF THE DISCLOSURE     A method and apparatus for cleaning surfaces using a high velocity stream or streams of cleaning fluid.          The high velocity stream or streams issue from one or more nozzles that are moving at a high velocity relative to the surface to be cleaned and are directed at the surface at an inclined angle thereto.  In one embodiment, the source of cleaning fluid is under a high pressure of about 200 to 700 pounds per square inch and the nozzles are moving in a direction so that the velocity imparted to the issuing stream by each moving nozzle adds to the already high velocity of the stream due to the high pressure alone of the source of cleaning fluid.  In another embod-iment, two nozzles are rotated at a high velocity about an axis perpendicular to the surface to be cleaned with each nozzle being directed at a different area of the surface and having a different flow rate, angle of inclination to the surface, spray pattern, and/or spraying arc.  The nozzles can be spaced at different distances from the axis of rotation in this embodiment and the closed paths sprayed by the nozzles as they move about an axis can be distinct or overlap.  In a preferred embodiment, the nozzle spraying the area farther from the axis of rotation sprays the smaller area and has the greater flow rate.  The spray patterns of the nozzles can be solid streams, fans, cones or any desired pattern.  In another embodiment, at least three nozzles are directed at the surface to be cleaned and rotated at high velocities about the axis of rotation.  In all of the embodiments, the flow rate, spray pattern, angle of inclination to the surface, spraying area, and spraying are for each nozzle can be individually set and the various nozzle arrangements can be easily removed and substituted one for another in the apparatus.  The various nozzle arrangements are new and novel and can be used with improved results in conventional cleaners that operate with the source of cleaning fluid under relatively low pressure.  The moving nozzles enable the invention to spray a given area quickly and with a minimum of cleaning fluid.  The apparatus can be operated with or without a driving motor for the rotating nozzles.  The invention further includes a vacuum pick up system and wall nozzles that enable the invention to clean near walls or at the edge of the carpet.

Abstract: ABSTRACT OF THE DISCLOSURE     In a switching circuit for controlling the level of material in a container, a first counter accumulates pulses generated at a rate inversely related to the level of the material up to a first predetermined total.  A second counter accumulates clock pulses up to a second predetermined total representing a fixed counting interval.  The counters are connected in a race circuit wherein the one to reach its predetermined total first resets both counters and controls the race circuitry.  The first counter sets a control circuit to indicate a low level condition or to activate an alarm, and the second counter resets the control circuit to indi-cate a high level condition.  After the control circuit has been set by the first counter, the race circuit is responsive to a third predetermined total of the first counter, less than the first predetermined total, representing, for example, a level to which a container is to be filled.  The first and third pre-determined totals provide a hysteresis effect to prevent the switching circuit from "hunting" around the level at which material is to be added or an alarm condition shown.

Abstract: ABSTRACT OF THE DISCLOSURE     An impact tool for mining, demolition work and the like.  An energy storing device such as a coil spring, when compressed! accelerates a hammer to deliver a blow to a working tool.  The hydraulic cocking mechanism has a compression chamber and a bias chamber.  A shaft extends through the compression chamber and into the bias chamber.  The shaft has an annular stop attached to it and reciprocally carries a compression sleeve above the annular stop.  A bias member extends into the bias chamber.  Input hydraulic pressure urges the bias member to press the compression sleeve into seating contact with the annular stop to define a piston.  Hydraulic input pressure acting at the same time below the piston urges the shaft upward to cock the spring.  At the top of the stroke, ports and passages reduce the pressure difference above and below the piston to allow the spring to force the shaft down for impact.  On the downstroke, the compression sleeve and annular stop separate.  Ports urge the sleeve back into sealing contact with the annular stop after impact. A re-silient member cooperating with the sleeve and annular stop reduce damage to the sealing surface.

Abstract: CLEANING SHOE FOR A COMBINE HARVESTER              Abstract of the Disclosure In a cleaning shoe for a combine harvester, threshed grain from the threshing cylinder and separator is received onto the upper run of an endless mesh belt conveyor or sieve band.  The sides of the upper run of the conveyor are guided in channels which may be oscillated in a vertical plane so as to agitate the upper run of the sieve band and promote the separation of grain from material other than grain as the material is conveyed rear-wardly, the grain passing downwards through openings in the mesh belt.  A second more conventional oscillating sieve element is mounted below the sieve band.  Grain cleaning efficiency is augmented by a blower and duct system which provides a plurality of longitudinally spaced, laterally extending elongated air nozzles disposed below the lower sieve element and each directing an air blast rearwardly and upwardly through it.  In an alternate embodiment, a third conventional sieve element is supported to move with the guide of the upper run of the sieve band so that it too is oscillated.  Discharge from the rearward edge of this third sieve element is received by a supplementary tailings conveyor.
