Abstract: ABSTRACT Disclosed is a wear-resistant high pressure pump for the handling of, particularly, abrasive slurries and suspensions, and which eliminates the problem of valve shear of the pressurized discharge product.  An oscillating-deflector slurry pump comprises a pair of cylinder arrangements aligned one on either side of a centrally-disposed oscillating-deflector element.  Each cylinder arrangement is constituted by a housing in which are defined co-axial, registering hydraulic and slurry cylinder bores, and a piston rod having, at one end thereof, a hydraulic piston head slidably movable within the hydraulic cylinder bore and having, at the other end thereof, a slurry piston head slid-ably movable within the slurry cylinder bore.  The oscillating-deflector element has within it passageways enabling communication, alternately, between a slurry inlet conduit and a first one of the two slurry cylinders, and between the slurry inlet conduit and a second one of the two slurry cylinders.  The second slurry cylinder is in communication with a slurry discharge conduit when the slurry inlet conduit is in communication with the first slurry cylinder, and the first slurry cylinder is in communication with the slurry discharge conduit when the slurry inlet conduit is in communication with the second slurry cy-linder.  The oscillating-deflector element has an axis of rotation normal to the longitudinal, reciprocal axes of the hydraulic and slurry cylinder bores, and is adapted to oscillate with an axial shaft, one end of which operates so as to oscillate the element and the other end of which carries valve means which controls selection of the direction of oscillation of the element.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and a method for measuring moisture in plastic pellets employing microwaves transmitted through volatiles, including water vapor driven from such a polymer sample by heating same in a closed test cell.         A pump is used to move a predried gas and those volatiles at an established pressure level and known flow rate to a microwave transducer.  The transducer has a pair of antennae horns aimed at one another and each re-spectively supporting a microwave transmitter oscillator and receiver detector.  The volatiles are the test sample which are brought transversely across the open end of the oscillator antenna horn by means of a conduit which is transparent to microwave energy.  The particular orientation of the conduit is important to the accuracy of the measure-ment.  A moisture absorbent material is inserted axially into the conduit to restrain the flow of volatiles through the conduit changing the vapor to liquid form.  Consequently, there is resident time for the water sample in the path of the microwave energy between the transmitter and detector.          The loss of microwave energy due to the vapors in the volatiles is measured at the output through the detector.          The transducer through which the microwave energy passes is surrounded by a microwave energy absorbent material whereby all of the energy transmitted is either received by the detector or absorbed by the absorber or water vapor in the test sample.  Calibration of the system is obtained by adjusting a zero control and setting a sensitivity control both of which influence the electronic circuitry that con-verts output to a readable form.         The method requires the steps of producing volatiles from a polymer sample; transmitting them with a dry gas at a known flow rate and pressure to be acted upon by microwave energy passing between a transmitter and detector; surrounding the environs of the oscillator and detector with a microwave absorber to control the transmission of microwave energy between the oscillator and the detector; measuring the loss of microwave energy at the detector which is a consequence of the water moisture from the volatiles; absorber in the flow path of the volatile to control the resident time of the water within the transmitted microwave energy.

Abstract: RESISTIVE RIBBON THERMAL TRANSFER    PRINTING SYSTEM AND PROCESS                     ABSTRACT            A technique and structure for resistive ribbon thermal transfer printing including a separate resistive ribbon and transfer ribbon therefor is illustrated.  The resistive ribbon is used only for the generation of heat and is placed in contact with a separate transfer ribbon including a very thin carrier ribbon coated with ink.  A moveable electrode printhead generates a heat pattern along the resistive ribbon and this pattern is compressed along the direction of printing by means of printhead motion v1.  The resistive ribbon is moved relative to the transfer ribbon at a velocity v2 so as to generate a heat flow in the transfer ribbon corresponding to the pattern required for normal printing.  The ink is melted and is transferred from the transfer ribbon to the paper.

Abstract: ABSTRACT OF THE DISCLOSURE             METHOD OF ATTENUATING SEA ICE FLEXURE NOISE DURING SEISMIC SURVEYS OF PERMAFROST REGIONS        The present invention indicates that in exploration of permafrost regions of the world for oil and gas accumulations, flexure noise can be attenuated by careful placement of the vibratory source vis-a-vis the receiver array during collection of the Vibroseis ? -type data.  It has been surprisingly found that if the explorationist adopts a survey strategy in which the vibratory source is separated from the receiver array by a pressure ridge or its equivalent over the ice formation of the region under survey, then the seismic reflection signals can be easily collected and displayed.  Result:  continuity of events from onshore reflectors can be easily followed offshore through the transition zone into deeper sea ice regions.
