Abstract: TWO-STAGE THERMAL AND CATALYTIC HYDROCRACKING                 OF HEAVY OILS            ABSTRACT OF THE DISCLOSURE          An improved process for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands, in which the charge oil in the presence of an excess of hydrogen is passed upwardly through a first vertical hydro-cracking zone in the absence of a catalyst, an effluent emerging from  the top of the zone is separated into a gaseous stream, containing a wide boiling range material from naphtha to heavy gas oil and a liquid stream containing heavy hydrocarbons, the gaseous stream together with added hydrogen is passed upwardly through a second vertical catalytic hydrogenating zone and the effluent from the catalytic hydrogenating zone is separated into a liquid product and a gaseous component containing predominantly hydrogen which can be reused.  This  process provides a simple and in-expensive procedure for obtaining from heavy oils lighter hydrocarbon oils having low sulphur and nitrogen contents.

Abstract: ABSTRACT The unitary spring clutch and actuator assembly has a spring clutch subassembly comprising a shaft for supporting two axially spaced input and output drums which are surrounded by a helically wound spring, one end of which is connected to a control sleeve or collar surrounding the spring.  The collar has a stop element which coasts with the actuator subassembly to control ro-tation of the collar and hence engagement or disengagement of the spring from the input and output drums.  The actuator subassembly includes a fixed frame for supporting an electro-magnetic control device which is adapted to engage and disengage from the stop element. The spring clutch and actuator subassemblies are secured together at one end portion of the shaft, which projects through an opening in the frame and by a retaining member constructed and arranged to engage the tubular shaft and frame.  A bearing is interposed between the shaft and frame to facilitate rotation of the shaft relative to the fixed frame.

Abstract: ABSTRACT OF THE DISCLOSURE             A class of new 4-amino-4-arylcyclohexanones, their ketals, and acid addition salts have been synthesized and found to be useful for relieving pain in animals. Their analgesic activity appears to be of high order, and in addition some exhibit narcotic antagonist activity that is useful in modifying the cardiovascular, respiratory and behavioral depression caused by other analgesics. Several show mixed analgesic and narcotic antagonist activity. Preferred compounds of the class are 4-(m-hydroxyphenyl)-4-dimethylaminocyclohexanone ethylene ketal, and 4-(m-hydroxy-phenyl)-4-(n-butylmethylamino)cyclohexanone ethylene ketal as free bases and as their hydrochloride salts. Processes for synthesis and intermediates are described. Unit dosage forms and therapeutic treatments are disclosed. The compounds of the invention have the formula:                             Formula 1 wherein X is oxo, and   wherein the substituents R1, R2, R3, R4 and R5 can be hydrogen or other substituents defined in the specification and n is zero or one.

Abstract: ABSTRACT OF THE DISCLOSURE     Wrapping apparatus in which shrink wrap material in web form is fed from a reel onto an apertured, rotating drum.  The interior of the drum is maintained at a sub-atmospheric pressure to draw the web against the drum.  An oscillating cutter is pressed against the web on the drum to sever the web into sheets, and the sheets are transferred to two apertured feed belts. Suction conditions maintained at the apertures in the belts holds the sheets against the belts.          These belts place the sheet curtain-like ahead of the article to be wrapped, and the article is fed by an infeed conveyor into engagement with the sheet. The sheet is draped over the article as it is fed forward onto a main conveyor, the leading edge portion of the sheet being between the article and the conveyor.  The trailing edge portion is blown or pushed through a slot in the main conveyor so that it hangs down below the main conveyor.  Movement of the article is then interrupted while the main conveyor continues to move.          This causes the trailing edge portion to be carried under the stationary article by the main conveyor so that the leading and trailing edge portions are overlapped.  Thereafter, the article is allowed to move with the main conveyor and the overlapped portions are secured together to form a sheath around the article.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of feeding fibrous ligno-cellulose raw material into a pressurized vessel such as a digester operating at approximately 300 pounds per square inch.  The raw material is first pre-compacted by a screw conveyor and subsequently compacted to a density of at least 45 pounds per cubic foot of oven dry material to form a plug in a feeding conduit communicating with the digester.  During the pre-compacting and compacting stage, the moisture of the material is maintained at a natural level of about 10% to 50% by weight.  The plug thus forms a continuously advancing mass of material which-separates the interior of the digester from the surrounding atmosphere without the need of special valve means normally used in prior art.  The advancement of the plug takes place along a straight line generally coincident with the centreline of the screw conveyor but axially spaced from same.

Abstract: EXTENDED TEMPERATURE-RANGE VALVE SEAL       ABSTRACT         A valve seal mechanism for use in pressurized fluid systems subject to fire risk, the seal having a soft seat to provide essentially zero leakage at normal operating temperatures and a backup hard metal seating surface capable of holding leakage to extremely low rates in the event of temperatures high enough to destroy the soft seat material.  The seal mechanism is in the form of a hard metal seal ring adapted to fit within an undercut circumferential groove in a valve seat.  The metal seal ring has a central inner circumferential rib adapted to extend through the groove opening for mating engagement with a sealing surface on the circumference of a valve disc.  The rib of the metal seal ring itself has a circumferential undercut groove into which is tightly fitted a seal ring of material softer than the metal of the seal ring, the soft seal ring protruding beyond the adjacent inner surface of the rib to provide a primary valve seat surface.  If the soft seal ring is destroyed by temperatures exceeding the normal operating range, the rib face provides an undamaged secondary valve seat surface.
