Title: Directional gamma ray spectrometer
Inventor: ARNOLD DAN M
IPC: G01T1/20
Filed: 1991-01-10
Abstract: ABSTRACT OF THE DISCLOSURE             This disclosure is directed to a scintillation crystal surrounded by a sleeve and having a window formed therein. The scintillation crystal has end located first and second photomultiplier tubes which provide output signals. A scintillation event observed in the crystal is seen by both photomultiplier tubes and both form output signals. The output signals have a relationship determining the point of impingement along the length of crystal of the photon gamma radiation; in turn, that photon is located relative to a surrounding shield having a helical window formed therein so that the relative angle of impingement can be determined. The relative angle is then converted into the absolute angle relative to the well borehole by referencing a north seeking gyroscope supported by the sonde. The output signals are also used to determine the energy of the impinging gamma radiation using well known pulse height analysis spectroscopy techniques.     86.167

Title: Solvent extraction process involving membrane separation of extract phase and/or intermediate zone phase with pseudo extract/pseudo raffinate recycle
Inventor: WELMERS ADRIANUS
IPC: B01D11/04
Filed: 1991-10-23
Abstract: Abstract of the Disclosure The solvent extraction of aromatics contain-ing oil using a selective aromatics extraction solvent to produce an aromatics rich extract phase and an oil rich/aromatics lean raffinate is improved by the steps of subjecting the extract phase to a membrane separa-tion step to produce a permeate phase and a retentate phase passing the retentate phase to a settling zone wherein the  retentate phase  spontaneously  separates into two liquid phases, and recycling the upper phase to the extraction zone, either to the feed inlet or to the  bottom  of  the  extract  reflux  zone  to  thereby increase the raffinate oil recovered from the extrac-tion tower.    Alternatively or in addition to the above, a side stream can be taken from an intermediate zone of the extraction zone (e.g. extraction tower) and fed to a membrane separation to produce a solvent rich perme-ate  and  an  oil  rich  retentate.   The  solvent  rich permeate is recycled while the oil rich retentate is fed to a settling zone wherein it will spontaneously separate into an oil rich pseudo raffinate upper phase which  is  recovered and  into a  solvent  rich pseudo extract bottoms phase which is recycled to the solvent extraction zone, preferably at a point below that at which the side stream was withdrawn.         The  membrane  separation  zone  preferably employs  interfacially  polymerized  membranes  under reverse osmosis conditions.

Filed: 1992-05-21
Abstract: SNOWBOARD SIMULATOR BALANCE APPARATUS               Abstract of the Disclosure An apparatus designed to allow the user to simulate the action of a snowboard during dryland training.  The apparatus has a cylindrical roller that has tapered or angled surface at the outer portions of the roller.   The tapered sections may have slots cut into them which would allow for a stepping effect from one tapered surface to the other.   Attached to the lower surface of the receiving board are spacers.  These spacers provide stability to the apparatus, while at the same time permitting unconventional radial  lateral and yaw motions to the receiving board and roller.  The receiving board is attached  to the lower surface of the upper deck by using vertical lifts attached between the receiving board and the upper deck.  The receiving board may also include a gripping surface material between the lower surface of the receiving board and the roller.  The upper surface or deck of the apparatus has a concave outer edge to provide increased surface contact with the feet of the user.  The center of the roller has a large slot cut therein to receive a guide rail connected to the horizontal centerline of the lower surface of the receiving board in order to keep the board centered over the roller.   The guide rail has adjustable end stops that allow the individual to change the length of the rail.          The apparatus may provide an axle located through the centerline of the roller that would permit the attachment of a bearing and wheel at the end of the tapered sections to allow for a tighter turning radius for the apparatus.
