Abstract: ABSTRACT            This invention relates to a valve suitable for location within a passage or bore of a piston or piston rod of a hydraulic ram assembly.  The valve includes a valve body mountable in the bore or passage and a chamber provided in the valve body having a pair of fluid access ports preferably having a relatively narrow outer passage and an enlarged inner space which may function as a valve seat. There is also provided a pair of valve members wherein each valve member may co-operate with a respective valve seat to close or open same to fluid flow through the valve chamber. The arrangement is such that in operation fluid flow into the valve chamber may occur only from the pressure side of a piston or piston rod accommodating the rod through a proximal access port wherein a distal access port is closed whereby prior to impact of the piston upon an end of an associated hydraulic cylinder the distal access port is opened to permit fluid flow to occur therethrough to the non pressure side of the piston from the valve chamber.

Abstract: ABSTRACT          A repaired elastomer article having a cut or crack entirely therethrough.  A treating agent is located about the cut portion on the inner surface of the article and an amine curable polymer or prepolymer layer resides over said treating agent.

Abstract: "SERIAL FLOW CONTINUOUS SEPARATION PROCESS"               ABSTRACT           A process for separating an extract component from a raffinate component contained in a feed mixture.  A unidirectional fluid flow system is maintained through a series of separating units through which the components travel at different rates.  The units are interconnected in series so as to form a single closed loop.  A component concentration distribution is established within the system of units so as to comprise a series of zones.  Feed and displacement fluid are each mixed with a different intercolumn stream prior to being passed into the inlets of two of the units and extract and raffinate are taken only as portions of streams from outlets of two or more of the units at appropriate points on the component concentration distribution.  At the appropriate times the inlets and outlets are shifted so as to simulate movement of the units in a direction downstream with respect to the direction of fluid flow and thereby enable the inlets and outlets to continually lie in the appropriate zones.

Abstract: Abstract of the Disclosure An aqueous dispersible, isocyanate-containing polymer or prepolymer or chain extended polymer is provided which has internal pendant, reactable silane groups and which can also have internal dispersing aids.  The aqueous dispersible, isocyanate-containing polymer, prepolymer, or chain extended polymer produces an aqueous dispersion of a polyurethane polymer having pendant reactable siliconate anions.  The isocyanate-containing polymer is prepared from polyisocyanates, organic compounds with at least 2 active hydrogens, and organosilane which is at least monofunctional in reaction with isocyanate groups on at least one organic moiety of the organosilane.  The organosilane also may have hydrolyzed or hydrolyzable groups associated with the silicone atom.  The prepolymer is formed at temperatures less than 200°C at atmospheric pressure in a one shot or two step process.  The polymer is combined with water to form an oil in-water dispersion, and, if it is a prepolymer, the molecular weight is increased through chain extension.  The pH of the aqueous dispersion of the polyurethane is maintained at least around 7 when the silyl concentration of the polymer is greater than 0.1 weight percent of the water in the dispersion.  The aqueous dispersion can also be prepared from a prepolymer that is devoid of any organosilane used as a comonomer and where the prepolymer is dispersed and chain-extended with the difunctional organo silane.  The aqueous dispersion of the polyurethane resin is used in coating myriad substrates such as inorganic oxide substrates.

Abstract: METHOD FOR PEARLITIC RAIL STEELS                    ABSTRACT OF THE DISCLOSURE         The present invention relates to a method for thermal treatment of pearlitic rail steel.  For increasing strength and wear resistance steels with the claimed composition are produced with a fine lamellar pearlite structure by heat treatment.  During the first cycle the rail head portion is heated in a sufficient depth of up to 50 mm by means of a burner or an inductive system to an austenitisation temperature of about 950 to 1050°C.  There-after the heated head portion is cooled by means of compressed air in such a way that in a first step by blowing a large amount of air the temperature of the rail head portion is cooled within 10 to 20 seconds to 650 to 600°C. before the area of the pearlitic transformation.  In a second step with throttled blowing compared to the first step in the area of the pearlitic transformation the rail head portion is cooled within 2 to 4 minutes to about 400°C until finishing the pearlitic transformation.  Then the rail head portion is again heated for 4 to 6 minutes to a temperature of about 600 to 650°C and then rapidly cooled by means of water or other appropriate quenching media to a temperature of less than 100 °C .

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention provides an automatic cut off switch which grounds the magneto-spark plug circuit of a small gasoline engine shutting the engine down when the quantity of lubricating oil within the sump falls below a predetermined quantity.  The switch is operated by a balance beam float assembly housed within a protective shroud. The protective shroud acts to collect a relatively stable pool of oil, representative of the quantity of oil remaining in the sump, for activation of the balance beam float.  Upon refilling of the oil sump the switch automatically resets thereby permitting re-start of the engine.

Abstract: ABSTRACT     A firing head for a tubing conveyed perforating gun is shown which is operated by pressuring the interior of the tubing  string.    A  sliding  sleeve  having  a  pressure responsive seal  area changes position at a predetermined increase  in  tubing  pressure.    As  the  sleeve  changes position, the production ports of the tool are first opened, allowing  communication  between  the  well  annulus  and  the tubing interior.  Movement of the sliding sleeve also drains an initially filled, hydraulic cylinder within the interior of the tool.   As the cylinder  is drained,  an associated fluid piston moves to occupy the evacuated chamber.   The fluid  piston  is  connected  to  a  firing  pin  holder  which releases the firing pin, allowing the firing pin to contact a percussion detonator to fire the perforating gun.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a optical data storage device and system, and a method of doing one or more of entering data into, reading data out of, or erasing data from the device.  The optical data storage device is characterized by an encapsulated structure including an optically non-transmissive, chalcogenide, phase changeable layer.  The phase changeable layer is sufficiently thick such that the impinging vitrifiying energy pulse does not vitrify all the way through the layer.          The disclosed method, in one exemplification, contemplates applying projected beam energy to the medium to change a discrete portion of the medium from a solid state of first relative order to a solid state of second relative order through an intermediate state of relatively high mobility.  projected beam energy is also applied to the medium to change the discrete portion of the medium from the state of second relative order through a relatively high mobility intermediate state back to the state of first relative order.          According to another exemplification, projected beam energy is applied to the memory medium to change a relatively narrow first track of the medium from a state of first relative order to a state of second relative order.  This exemplification further contemplates applying projected beam energy to the memory medium to change a second track of the medium wider than the first track from the state of second relative order to the state of first relative order, whereby said second track encompasses said first track, together with areas of completely and incompletely cycled memory material which lie substantially outside of said first track.
