Abstract: Abstract of the Disclosure The cutter head of a reamer carries a circular tool bit and two guide members.  Each guide member has an outer-most edge at the furthest distance from the center of rotation of the tool and slanted edges inclined at progressively greater angles from the outer edge towards the front of the tool where the initial cut takes place.  The first slanted edge, at an angle of less than 10 degrees and preferably between 3 and 5 degrees, intersects the outer-most edge at a point which lags the extreme point on the tool bit by about 0.4 mm in the direc-tion of advance of the tool.  The first slanted edge extends at least to the radial plane containing the extreme point of the tool bit.  Thereafter, a slanted edge at an angle inclined between 15 and 25 degrees extends in the forward direction, to be followed by a third slanted edge inclined at an angle to the outer-most edge of between 30 and 75 degrees. The exact angles of inclination are determined by the diameter of the circular tool bit, which, in turn, is determined by the material to be cut.

Abstract: TITLE OF THE INVENTION:            PRINTING APPARATUS AND PROCESS            ABSTRACT OF THE DISCLOSURE:       A printing apparatus is disclosed wherein rocking motion of a movably mounted inking roll assembly is controlled by a cam and follower arrangement coupled to the drive system for a pivoting printing member. The cam and follower arrangement allows coordinated movement of the printing member and inking roll assembly to be obtained in a simple manner and without employing separate drive means for rocking the inking roll assembly. The cam contour is advantageously chosen so that the inking roll is moved gradually toward and then away from the pivot axis of the printing member as the line of contact between the printing element and the inking roll progresses from the leading edge of the printing element to the trailing edge. Such movement of the inking roll maintains uniform tangential contact between the inking roll and the entire surface of a flat printing element as the latter is moved in an arcuate path by the printing member. Also disclosed is a resilient mounting arrangement for the printing member which allows movement of the printing member along separate arcuate and straight-line paths at different times under the control of a single drive means.

Abstract: ABSTRACT       ELECTRODIALYTIC WATER SPLITTING PROCESS AND APPARATUS FOR CONVERSION OF ALKALI METAL SULFATE    VALUES DERIVED FROM SPENT RAYON SPIN BATHS _ A process and apparatus for converting alkali metal sulfate values such as sodium or potassium sulfate values in spent rayon spin bath liquors, into alkali metal hydroxide and alkali metal sulfate/sulfuric acid by using two- or three-compartment electrodialytic water splitter cells.  The process and apparatus incorporate the features of: (a) feeding a liquid comprising water to the base compartment of an electrodialytic water splitter;  (b) feeding a liquid comprising alkali metal sulfate values to the remaining compartments of the electrodialytic water splitter;  (c) passing current through said electrodialytic water splitter to produce a liquid comprising alkali metal sulfate and sulfuric acid in one of the remaining compartments and a liquid comprising alkali metal hydroxide in said base compartment comprising.  The liquid fed to the acid compartments of two- and three-compartment cells may contain H2SO4.  When more than about 5 weight percent H2SO4 is present in the alkali metal sulfate solution to be fed to the acid compartment, use of three-compartment water splitter is preferred.  Improved results are obtained when the compartments of the two- and three-compartment water splitter are maintained at a temperature of at least 40°C.

Abstract: Abstract of the Disclosure A side pocket mandrel has an elongated receptacle in the side pocket  parallel with the main bore.  A lateral side port communicates the receptacle with the exterior of the side pocket of the mandrel.  A flow control assembly includes a sliding sleeve valve and a control valve, both designed to be removable from the receptacle.  The sleeve valve is movable within the receptacle between a closed position and an open position relative to the side port, and includes collet fingers having outwardly projecting latching lugs for engagement in a receptacle latching recess in the closed position.  The bore of the receptacle is slightly larger below the latching recess than it is above the recess, so that limited inward movement of the latching lugs, restrained by an insert within the sleeve valve, will permit movement of the valve downward to the open position but will not allow movement of the valve upward from the closed position, so long as the insert is in place.  A control valve, to be selectively placed within the receptacle and latched with the sleeve valve includes a nose which is received within the sleeve valve and limits the inward deflection of the collet finger latching lugs.  The control valve includes a latching lug for latching in another receptacle latching recess, when the sleeve valve has been moved to the lower open position.          The control valve and sleeve valve have a coacting latching mechanism so that when the control valve is withdrawn, it lifts the sleeve valve to the closed       position and then disengages from the sleeve valve.  The sleeve valve includes an internal latching recess to enable withdrawal of the sleeve valve from the receptacle by a suitable pulling tool.

Abstract: ABSTRACT OF THE DISCLOSURE     A shock absorber control system controls vehicle shock absorbers by bringing them selectively into a softer dampening mode or a harder dampening mode in response to operation of a steering wheel of a vehicle.  The shock absorbers are changed from the softer to the harder dampening mode only when the vehicle speed is higher than a reference vehicle speed and the steering wheel is turned at an angular velocity greater than a predetermined reference angular velocity.  The angular velocity of rotation of the steering wheel is used as a parameter to select one of the softer and harder dampening modes only when the vehicle wheel has been angularly moved beyond a certain reference angle dependent on the vehicle speed.  Therefore, no unwanted switching between the softer and harder dampening modes takes place when the steering wheel is angularly moved back and forth through relatively small angles.  The harder dampening mode continues for a preset interval of time.

Abstract: SOLVENT ASSISTED STEAM INJECTION PROCESS      FOR RECOVERY OF VISCOUS OIL                          ABSTRACT          A method for recovery of viscous oil from a subterranean, viscous oil-containing formation employing mixture of steam and 2 to 5% of a light solvent having an equilibrium K-value of at least 0.5 at initial formation temperature and pressure that results in maximum solvent efficiency based upon the ratio of cumulative oil recovered to the amount of solvent injected and unrecovered.  A predetermined amount of a mixture of steam and 2 to 5% by volume of a light solvent having the desired equilibrium K-value is injected into the lower 50% or less of the formation via an injection well and fluids including oil and a portion of the light solvent are produced from the upper 50% or more of the formation via a spaced-apart production well.  The amount of steam injected is 0.30 to 0.50 pore volume at a temperature of 500°F to 700°F, a quality of 50 to 90%, and an injection rate of 4 to 7 barrels (CWE) per day per acre-foot of formation.  Thereafter, production of fluids including oil and light solvent is continued until steam breakthrough occurs or until the fluid being produced contains a predetermined amount of water, preferably at least 95%.          The method is applied to a viscous oil-containing formation in which either naturally occurring or induced communication exists between the injection well and the production well in the bottom zone of the formation.  Suitable light solvents include C1 to C4 hydrocarbons and carbon dioxide.  In another embodiment of the invention, injection of the mixture of steam and solvent may be continued and fluids including oil and solvent are produced until steam breakthrough occurs or until the water cut of the produced fluid contains at least 95% water.
