Abstract: BC1-25 Canada FIBER REINFORCED CARBON AND GRAPHITE ARTICLES AND        A METHOD OF PRODUCING SAID ARTICLES                       ABSTRACT      The present invention relates to fiber reinforced carbon and graphite articles that are characterized by a matrix of fibrous carbon material bonded together by a deposited pyrolytic material and having the residue of a carbonized filler material dispersed within the article in contact with the pyrolytic material.     Fiber reinforced carbon and graphite articles are produced by (1) Forming reinforcing fibers into a shape without any binder material, (2) infiltrating he fibers with a pyrolytic material in a manner to deposit pyrolytic material on the fibers and bond together the fibers, to form a bonded body, (3) Subsequently impregnating the bonded body with a carbon-izable filler material, and, (4) Curing and carbonizing the filler material. The articles are substantially free of internal cracks and voids and are of high strength even at relatively low densities. As such, the articles are particularly useful in the aerospace industry where strong, lightweight materials are required. The articles of the present invention are found to have substantially improved freedom of internal stresses which prior art carbon or graphite articles have been particularly susceptible.

Abstract: 1.            BE IT KNOWN THAT CHANG YUL CHA of 1904 Glenmont Drive, Bakersfield, California 93309, United States of America, having made an invention entitled:     "In situ oil shale retorting"     the following disclosure contains a correct and full description of the invention and of the best mode known to the inventor of taking advantage of the same.            ABSTRACT A locus of processing zone advancing during retorting through a fragmented permeable mass of particles containing oil shale in an in situ oil shale retort in a subterranean formation containing oil shale is determined by monitoring off gas passing from the retort to determine the content in the off gas of a selected constituent formed, by advance-ment of the processing zone through the fragmented mass, from a corresponding precursor contained in the formation particles,  The locus of the processing zone is convenient-ly determined by comparing measured and predicted values of the content, rate of production and/or total production of the constituent in the off gas, the predicted values being calculated from the measured content of the precursor at a plurality of locations in the retort along the path of advancement of the processing zone.   One preferred precursor:constituent pair is kerogen:methane.

Abstract: SWIVEL HOOK ATTACHMENT FOR ARTICLE HANGERS               ABSTRACT OF THE DISCLOSURE           A garment hanger is disclosed which has a molded plastic body to which a separate, preferably metal, hook is attached after the molding is complete.  The molded body has a locking collar molded integrally with it but attached by a weak, rupturable web or stem.  When the hook is assembled to the body, its shank is forced through the collar so that the collar becomes firmly secured to the shank and thereafter prevents separation of the hook and body.  In one form of the invention, the forcing of the shank through the collar detaches it from the body, permitting the collar and hook to rotate freely with respect to the hanger body.  In another form, the attachment between the hook and body remain intact until a subsequent maneuver is performed to cause separation of hook and hanger body.

Abstract: ABSTRACT OF THE DISCLOSURE            Apparatus and method for determining the concentration of a a constituent in a sample using chromatographic and optical measuring techniques.  A sample containing a constituent to be analyzed is fractionated by a chromatographic column.  A light beam is passed through the constituent fraction in the column, and the light absorbance (or transmittance) is measured.  The fluid carrier (or solvent) eluting through the column will generally increase the transmissivity of the light passing through the column due to a difference between the indices of refraction of the carrier fluid and the chromatographic packing material.  Such increased transmissivity will generally offset any decrease in the transmittance due to trace amounts of the constituent in the sample.  The optical measurement is compensated to nullify such increased transmissivity, so as to allow measurement of such trace amounts of constituents, Docket 2071-A              - 1 -

The inlet opening is defined by stays which extend between two seats co-operating with the valve means.  There is arranged around the inner wall of the housing of said chamber a liquid collecting groove which is connected by means of one or more channels with the interior of a tubular connecting means for the pipe.  Each such channel is arranged in a stay.

Abstract: TREATING UNDERGROUND FORMATIONS           (D#73,415-F) ABSTRACT OF THE DISCLOSURE          Disclosed is a method for treating subterranean formations such as underground petroleum-containing forma-tions penetrated by a well,  and particularly a formation penetrated by a producing well which formation contain a plurality of zones,  one or more of which are producing petroleum and one or more of which are producing water.  The treatment selectively reduces the permeability of the water-producing intervals without adversely affecting the permeabi-lity of the oil producing intervals, thereby reducing the production of water and reducing the water-oil ratio of the fluid being produced from the well.  The treatment method involves introducing an effective amount of a liquid compris-ing a hydrocarbon having dispersed therein an unhydrated water swellable clay such as bentonite, a sodium montmoril-lonite.  The clay swells on contacting water in the water-producing intervals and plugs or reduces the permeability of the flow channels in the water-producing intervals.                           -I-

Abstract: CONNECTOR WITH PERFORABLE INSULATIVE LINDER AND METHODS OF              FABRICATING SAME        Abstract of the Disclosure An open-ended, B-wire type of deformable connector has a thin, perforable insulative liner secured to the inner surface of the inner one of a pair of telescopically coaxially disposed metallic sleeves in accordance with several preferred liner assembly methods. The liner is positioned so as to overlie the distal ends of an array of insulation-piercing protuberances formed in the inner sleeve, and to extend con-tinuously in both the circumferential and longitudinal direc-tions at least to the perimeter of the array. During assembly, while the inner sleeve is being fabricated cut of strip stock in a progressive manner, each liner in the form of a section of thin, plastic film stock is positioned on and firmly secured (such as by pressure bending) to the partially fabricated planar sleeve section along at least the solid wall border regions thereof (surrounding the array of protuberances). As such, the assembled liner not only remains taut in the axial direction while overlying the distal ends of the protuberances of the fabricated sleeve, but presents no peripheral edge obstruction to inserted con-ductors, particularly at the open end of the composite con-nector as assembled. The preferred methods of assembling the liners are also advantageously conducive to high volume, automated manufacture, at minimal cost, as such assembly may be carried out sequentially with the work functions normally performed on the strip stock from which the inner sleeves are fabricated.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to an improved method for enhanced recovery of oil from relatively "cold" reservoirs by carbon dioxide flooding.  In oil reservoirs at a temperature less than the critical tem-perature of 87.7°F and at a pore pressure greater than the saturation pressure of carbon dioxide at the temperature of the reservoir, the carbon dioxide remains in the liquid state which does not satisfactorily mix with the oil.  However, applicants have found that carbon dioxide can be vaporized in situ in the reservoir by selectively reducing the pore pressure in the reservoir to a value less than the particular saturated vapor pressure so as to greatly enhance the mixing of the carbon dioxide with the oil.
