Abstract: ABSTRACT                  HIGH-FLOW OSCILLATOR        A small, but nevertheless high-flow fluidic oscillator has a dual level body portion including an interaction chamber in a first level.  An inlet plenum supplies fluid to a supply nozzle which enters directly into the inlet end of the interaction chamber to direct a jet flow from the supply nozzle, through the inter-action chamber and out of an outlet opening.  A fluid passage is located at least partly in the second level of the body portion, and connecting passages on either side of the supply nozzle connect the fluid passage to the inlet end of the interaction chamber.  The wails of the interaction chamber converge from the inlet end toward a neck portion and thereafter diverge and then converge again at the outlet so that a fluid column extends between the jet flow and the sidewalls of the interaction chamber, and moves cyclically back and forth through the fluid passage and the connecting passages to obtain interaction between the fluid column and the jet flow without the need for control nozzles.

Abstract: METHOD OF TEMPERATURE COMPENSATING LEAK RATE TESTING           ABSTRACT OF THE DISCLOSURE           A method of compensating for temperature varia-tions in testing part cavities for leaks by placing a fluid pressure source in communication with the cavity and measuring the flow rate to the cavity to determine the rate of any leakage.  The method establishes a temperature com-pensation function by measuring the shift in flow rates resulting from changes in temperature of a sample test part, which temperature compensation  function allows cor-rection of the flow rates during subsequent testing accord-ing to the sensed temperature of the test part.  Flow rates are measured at two differing temperatures to determine the temperature compensation  function by linear regression, since the flow rate shift with temperature varies substan-tially linearly.

Abstract: "RETRIEVABLE HYDROSTATIC TESTING TOOL FOR         PRESSURE TESTING TUBING"                        ABSTRACT OF THE DISCLOSURE In common with conventional testing tools for this purpose, the present tool incorporates a central mandrel carrying a pair of vertically spaced packers which are expandable by fluid pressure, which mandrel  forms  a longitudinal bore having an outlet communicating with the annular space between the packers.  In contradistinction to the  prior tools, the bow spring and slips suspending assembly of the prior tools has been eliminated.  Instead, the packers themselves are relied on to suspend or fix the tool in the tubing.  To achieve this end, a novel valve assembly has been provided to control the admittance and bleeding off of pressurized Fluid into the annular space.  The valve assembly is adapted to first admit pressurized fluid into the annular space to set the packers and pressure test the tubing wall between the packers at relatively high pressure, for example 5000 psi.  The valve assembly is further adapted to cooperate in bleeding off the pressure from the annular space until it just exceeds that amount required to hold the packers set, say 600 psi; the valve assembly then automatically closes, to trap the 600 psi pressure in the annular space so that the packers maintain the tool in a suspended state.  A second stand of tubing can then be added to the tested stand and lowered into the well bore until said second stand's upper end seats in the wellhead.  A cable overshot is then used to open the valve assembly, to bleed off the 600 psi, following which the packers collapse and the tool can be retrieved.

Abstract: ABSTRACT       An optical communication system including repeaters which return a preamble signal to the receive line as soon as it detects a carrier on the transmit line of a single line optical bus. Therefore, transmission equipment can confirm data transmission quickly because the time delay between data transmission and its confirmation is decreased. The repeater also monitors a time delay associated with the return through a return loop of the transmitted data, and produces and transmits a failure signal when the time delay is longer than a predetermined value. The system also includes an optical transceiver connected between the optical bus and the transmission equipment which converts optical signals into electrical signals and visa versa and also adds the preamble signal to the front  of data to be transmitted.

Abstract: SYNTHETIC GRASS PLAYING FIELD SURFACE                     ABSTRACT OF THE DISCLOSURE   A playing field surface for active running and body contact type sports, such as football and the like, is formed of a stabilized, flat base surface covered by an underpad, over which is laid a synthetic pile fiber carpet. A covering of sand-like granules is applied upon the carpet to substantially fill the spaces between the fibers. The underpad is made of reclaimed rubber, sliver-like small particles which are bonded together into a thick, water pervious mat. The lower surface of the underpad is formed with widely and regularly spaced apart, dimple-like indentations and downwardly extending, rounded hills that contact the base surface. The hills are separated by rounded indented ridges which are of a lesser depth than the indentations. Each of the indentations is surrounded by a number of hills and ridges to provide resilient dome-like, interconnected, downwardly open pockets in the bottom surface of the underpad. The piles are formed of U-shaped, double bent fibers having bights looped through and extending downwardly beneath a carpet base sheet to form numerous welts. The welts are aligned in parallel serpentine rows and dig into and frictionally interlock with the particles forming the upper surface of the underpad. The playing field surface provides good support for lateral foot movements and resiliently absorbs and disperses the forces of foot and body impacts.

Abstract: ABSTRACT OF THE DISCLOSURE           Synthesis gas is produced by the partial oxidation of a fuel feedstock comprising a heavy liquid and/or petroleum coke having a nickel,  iron,  and vanadium-containing ash.  A copper-containing additive is introduced into the reaction zone along with the feed. The additive combines with at least a portion of the nickel and iron constituents and the sulfur found in the feedstock to produce a liquid phase washing agent that  collects  and  transports  at  least  a  portion  of  the vanadium-containing  oxide  laths  and  spinels  and  other  ash components out of the reaction zone.  In another embodiment, a minor amount of a second additive comprising a compound of an element selected from the group consisting of iron, calcium, magnesium, chromium, and mixtures thereof is introduced into the  partial  oxidation  reaction  zone  along  with  the  fuel feedstock and the copper-containing additive.  In still another embodiment,  the copper-containing additive with or without a supplemental compound of an element selected from the group consisting of iron, calcium, magnesium, chromium, and mixtures thereof  is  uniformly  dispersed  in petroleum coke  having  a nickel,  iron,  and vanadium-containing  ash.  By  this method molten  slag  having  a  reduced viscosity  and  containing  the nickel,  iron,  and  vanadium-containing  impurities  from  the feedstock are readily removed from the partial oxidation gas generator at a lower temperature.   Further, the life of the refractory lining of the partial oxidation gas generator is extended.
