Abstract: Abstract of the Disclosure A method and apparatus is provided for separating a carrier fluid from particles held in suspension in the fluid and which are of greater density than the fluid.  The apparatus includes a rotatably mounted frame and a screen mounted on the frame and extending in a largely radial direction from the axis of rotation of the frame.  A feed conduit feeds fluid with sus-pended particles therein along a first face of the screen, while a filtrate conduit carries away fluid which passes through the screen and a concentrate conduit carries away fluid with a high concentration of particles therein which has passed across the first face of the screen without passing through the screen.  The frame is rapidly rotated so that a large centrifugal force is applied to the fluid and particles therein as it moves along the screen. The centrifugal force urges the particles to settle out of the fluid in a radially outward direction, so that the major force on the particles urges them radially outwardly rather than through the screen.  Even particles much smaller than the holes in the screen tend to precipitate outwardly rather than flowing through the screen, and there is a minimal buildup of large particles on the screen that would tend to block it and reduce the flow rate.  The combination of a centrifuge action that urges particles radially outwardly together with the use of a screen that is oriented primarily perpendicular to radially outward flow results in a greater flow of filtered fluid than has been possible using either centrifuge separation or screening through a stationary or only slowly moving screen.

Abstract: FLUID OPERATED SEISMIC GENERATOR                 ABSTRACT OF THE DISCLOSURE         In the field of seismic exploration, compressed-air guns may be used as sound sources.  Known air guns employed complex valving and were wasteful of compressed air.  The air gun sound source of this invention is of simple construction and is economical of compressed air. The gun (10) consists of an elongated housing (34) that has at least one radially-positioned exhaust port.  The housing is charged with a volume of compressed air.  A hollow cylindrical actuator (60) is mounted inside the housing and may be hydraulically or pneumatically driven with-in the housing in longitudinal strokes.  The actuator has at least one radially positioned aperture (88) alignable with the exhaust port.  A valve or sealing pad (96) is mounted in each aperture.          An orifice (104) is cut into each pad. At one end of an  actuator stroke, the valve blocks the exhaust port in the housing.  When the shuttle is driven from one end of the housing to the other, as the valve orifice passes by the exhaust port, the exhaust port is opened momentarily to allow the explosive escape of some of the compressed air in the gun.  As the actuator completes its stroke  to the other end of the housing, the exhaust port is again blocked.

Abstract: DIGITAL COMPUTER WITH OVERLAPPED OPERATION UTILIZING CONDITIONAL CONTROL TO MINIMIZE TIME LOSSES               ABSTRACT OF THE DISCLOSURE        The disclosed computer is configured to perform its operations in overlapped fashion.  During each computer cycle the next instruction is fetched, the function designated by the previous instruction is executed, and values are stored that were computed with respect to the instruction previous to the one being executed.  Thus a three-way overlap is effected.  To minimize time penalties due to conditional branches and jumps, each instruction word includes two next instruction address fields, two function fields and two deferred action fields.  The computer includes decision logic for providing binary decision signals for conditionally selecting one of the fields from each of the next address fields, the function fields and the deferred action fields thereby conditionally fetching the next instruction conditionally selecting the function to be performed and condi-tionally storing values during the same cycle in accordance with the decision signals.  Thus the computer has the capability of performing conditional branches each cycle, in an unbroken rhythm without the wasted cycles that would otherwise be required in a highly overlapped architecture in view of conditional jumps.
