Abstract: Abstract of the Disclosure An improved plug valve is of the type that includes a valve body having a bore extending therethrough and a pair of passages in-tersecting the bore and being substantially normal to the axis of the bore.  a valve plug is disposed within the bore for selective rotation between an opened and a closed position to respectively align and mis-align a port through the plug with the passages.  A first circumferential sealing member between the plug and the bore above the port and the passages and a second circumferential sealing member between the plug and the bore below the port prevents fluid from escaping from an interior of the plug valve and balances fluid pressure acting on the plug.  The improvements include providing opposed circumferential semicircular grooves respectively on the bore and the plug to define a circumferential channel therebetween.  The body includes a circular hole extending therethrough which is tangentially aligned with the channel.  A flexible rod extends through the hole and around the channel for retention of the plug within the bore.  A bottom insert is fitted within the bore to enclose the base of the plug within the body and allows fluid to escape from below the plug if the second sealing member should fail.  A cir-cumferential sealing device around the top of the plug prevents ingress of foreign matter into the region of the bore above the first sealing member.

Abstract: METHOD AND APPARATUS FOR PRODUCING FIBER PULP         FROM FIBROUS LIGNOCELLULOSE CONTAINING MATERIAL     ABSTRACT OF THE DISCLOSURE       Method and apparatus for producing thermo-mechanical pulp from wood chips and the like in which the chips are first heated in a steaming chamber or preheater to a fiber temperature below the softening point of the lignin of middle lamella section of the wood fibers.  The thus heated chips are conveyed in a sealed system to the inlet of a defibrating zone enclosed within a housing in a gas-eous atmosphere of superatmospheric pressure, where it is compressed by a screw conveyor into a plug which seals the defibrator housing against blow-back of the pressurized gaseous medium.  The defibrat-ing space is defined between a pair of grinding discs which rotate relatively to one another in the housing and comprises a first sub-stantially central, relatively low friction zone into which the com-pressed plug is advanced by the compressor screw and broken up into fiber bundles and the fibers subjected to an initial defibration step at a fiber temperature below the softening point of the lig-nin, to cause the fibers to unravel and to expose the different fiber layers without any substantial separation thereof.  As the fiber bundles progress radially outwards under the centrifugal force of the rotating discs into a second relatively high friction zone radially surrounding the first zone, the temperature increases by the heat of the grinding friction which converts water accompany-ing the chips into high temperature, high pressure steam, in which environment the lignin is softened so that the wood structure is broken in the lignin-rich middle lamella section of the fibers to permit the fibers to become completely separated and fibrillated in undamaged condition.  The resultant pulp is discharged from the pressurized housing through a blow valve which is adjustable to con-trol the pressure and temperature within the defibrator housing.

Abstract: ABSTRACT OF THE DISCLOSURE:      Hydraulically activated, spaced apart, front end loader support arms extend from a tractor.  A loader attach-ment includes a vertically extending frame pivotally attached to the support arms forwardly of the tractor.  This vertical frame includes a main horizontal frame support bar pivotally mounted in outer ends of the support arms, and a pair of open vertical guides which extend downwardly from the frame support bar.  A horizontal hook support bar extends through the vertical guides and pivotally supports central portions of the two jaw-forming hooks at each end thereof.  Upper ends of each of these hooks are pivotally connected to links which are pivotally connected to the frame support bar.  A vertical hook support bar lifting strap extends integrally up from the hook support bar and is in sliding relationship with respect to the frame support bar.  To load, means is provided to raise the lifting strap with respect to the main frame, thus to cause the jaws to be opened.  The support arms are then lowered to encompass a log to be lifted.  The lift-ing strap is allowed to drop by gravity to cause the hooks of the jaws to close on the object to be lifted, and the loader support arms are lifted to raise the log from the ground.  To unload, the support arms are lowered, and when the log comes in touch with the ground, the further progress of the loader support arms in downward direction will cause the jaws to be released.

Abstract: OIL RECOVERY PROCESS BY IN SITU EMULSIFICATION                (D#71,914-F) ABSTRACT OF THE DISCLOSURE         Petroleum may be recovered from subterranean, petroleum-containing formations by injecting into the formation an organic liquid having dispersed therein, an alkali metal in very fine, preferably colloidal size range, particular form.  The organic liquid containing the alkali metal dispersion is followed by injecting an aqueous fluid to react with the alkali metal, generating alkali metal hydroxide, hydrogen gas and heat in the formation which stimulates displacement of the petroleum by encouraging formation of low viscosity oil-in-water emulsions, as well as by thermal viscosity reduction effects, and dissolution of hydrogen gas in the viscous petroleum.  The organic liquid having alkali metal dispersed therein may be preceded or followed by injecting crude petroleum from another formation which is prone to emulsify spontaneously and aid in the formation of low viscosity oil-in water emulsions.  Liquids containing emulsifying agents may also be used in combination with the present process, injected either in advance of or after injection of the organic liquid having alkali metal particles dispersed therein.  Alkali metals suitable for use in this invention include sodium, potassium and lithium.  This process may be used in combination with thermal stimulation processes including steam and/or hot water injection.     -I-
