Abstract: CARBON DECANTER  (D#70,524-F) ABSTRACT OF THE INVENTION This is an apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular.  Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom.  The liquid mixture of particulate carbon, water, and liquid organic extractant is charged into said vessel by way of a conduit which terminates at a position within the vessel along the vertical axis about 1/4 to 3/4 of the vessel height and below the interface level which is formed in said vessel when the two immiscible liquids separate by gravity with the water forming a pool at the bottom of the vessel. Alter-nately, the decanter may be charged through two concentric pipes.  A horizontal radial nozzle terminates each pipe. By this means the aforesaid mixture of immiscible liquids may be introduced into the decanter by way of an annular passage located between said pipes.  Further, simultaneously a separate stream of liquid organic extractant may be passed through the center pipe and discharged adjacent to the interface level.  The dispersion of particulate carbon-liquid organic extractant separates from the water and may be removed by way of the top port as a continuous stream.          Simultaneously, a continuous stream of clarified water may be removed from the bottom port.                             -I-

Abstract: ABSTRACT OF THE DISCLOSURE         A dust collection system particularly useful in conjunc-tion with hard rock drilling where a relatively large quantity of water is encountered in the drilling operation.  Wetted rock par-ticles and dust are collected, by air suction, in a hood about the drill rod and are carried through a venturi, assisted by induced air, into a first stage separator where the heavy cuttings are in-tercepted by a screen and discharged through a rubber valve.          Light cuttings and a quantity of dust are intercepted by further screens and discharged through a rubber valve.  Remaining dust is discharged from the first stage separator through a venturi assis-ted by induced air and delivered tangentially into the lower por-tion of a second stage separator.  A large proportion of the dust is discharged through the bottom of the second stage separator into collector bags and the remainder of the dust is carried upwards through a series of screens where a further quantity of dust is intercepted to fall down to the bottom of the separator, assisted by streams of air directed across individual screens and a conduit having openings at each screen level for collecting material picked up by the streams of air and by the conduit to the lower portion of the second stage separator.  The small quantity of dust passing through the screens passes upwards through a venturi and is dis-charged, assisted by induced air, as a light plume.  Air under pressure is directed against the screens in both the first and second stage separators in order to clean the screens of dust.

Abstract: ABSTRACT           A digital to analog resolver converter uses a digital to analog converter to convert a part of the digital input to a corresponding analog angle value.  This analog angle value is applied to since and cosine function gen-erators which use the equations of chords to approximate the value of the sine and consine functions in one octant.          Bits of the digital input are used to select slope values from the chord equations for approximating the sine and cosine of the analog angle value.  The digital to analog resolver converter uses the minimum number of precision resistors to generate the sine and cosine slope and inter-cept values for the equations of a given number of approx-imating chords.

Abstract: Spiral Pipe Forming Machine With Device For Aligning Spiralling Rolls Abstract of the Disclosure An improved apparatus for continuously forming spirally corru-gated metal pipe from an elongated sheet of metal which is first impressed with longitudinal corrugations in a corrugating device and then spiralled into a pipe in a three roll forming device, each roll of which is composed of a plurality of individual rollers.          Each individual roller is mounted for rotation about its axis in an individual roller yoke, with each of the roller yokes of each roll being in constant abutment, but with adjacent roller yokes being uninterconnected.  Individual roller yokes of each roll are posi-tioned along a guide, with each yoke being both freely displaceable along the guide along a horizontal path generally parallel to the axis of the formed pipe, and also pivotable about a vertical center axis.  One of the rolls, termed herein a horn roll, is situated to contact the inner wall of the pipe as it is formed, while the other two rolls, respectively termed the lead and buttress rolls, are situated to contact the outer wall of the pipe.  A rigid frame member is attached to the corrugating device, extending from the corruga-ting device into the three roll forming device in contact with either end of each of the lead and buttress rolls.  The buttress roll is the farthest downstream of the three rolls and is adjustable on an angle to the vertical in order to vary the diameter of suc-cessive helical convolutions of the metal sheet, therefore varying the diameter of the pipe produced.  A downwardly depending adjust-ment arm is attached to an end roller yoke of the horn roll and slideably engages the rigid frame member.  When the corrugating device is pivoted relative to the three roll forming device, the rigid frame member automatically relocates the positions of each of the three rolls and adjusts spacings between center axes of adjacent rollers of each roll to assure that the individual rollers constantly and correctly align with the corrugations of the metal sheet as it enters the forming device and is spiralled into helical convolutions.

Abstract: ABSTRACT OF THE DISCLOSURE    A device for interconverting linear and rotatory motions, and particularly a pressure fluid operated actuator for rotary plug valves and the like.  A piston axially slideable and rotatable in a cylinder is supported by first and second sets of connecting elements which are spaced from and inclined to the axis of the cylinder.  Each element of one set is pivotally connected at one end with a fixed member and at the other with the piston.  Each element of the other set is pivotally connected at one end with the piston and at the other with a rotary output element, for example, a shaft.  Axial movement of the piston is translated into rotatory movement of the output element by pivotal action of the connecting elements.  The connecting elements of the first and second sets extend from the fixed member to the piston and from the piston to the output element in opposite circumferential directions.          This configuration enables the torque characteristic to be tailored readily to suit particular applications by appropriate selection of the relative dimensions of the components of the device.

Abstract: ABSTRACT OF THE DISCLOSURE         A tree cutting method and apparatus includes at least one shear blade having its tree contacting edge recessed to define a pair of spaced shearing edges with a fiber receiving groove therebetween.  A fiber removing device is recessed within the groove out of contact with the solid wood of the tree and is preferably in the form of a driven endless fiber removing chain.  As pressure is applied by the spaced shearing edges of shear projections of the blade against the tree, the fiber removing device removes the fibers that are fed into the groove.  The removal of fibers greatly reduces the transverse force required by the shear blade to penetrate the tree or bole, and further reduces the resulting longitudinal shearing forces applied to the tree due to the longitudinal compression as the blade moves transversely through the tree thereby minimizing longitudinal splitting of the bole.          The partially crushed fibers require less force than a saw cutting through solid wood to remove the wood from the tree during the severing operation.              -1a-
