Abstract: ABSTRACT OF THE DISCLOSURE A component comprised of a composite compact, preferably diamond, and a substrate bonded to the compact. A preferred embodiment of the com-ponent is a cutter for a drill bit. The compact is comprised of a layer of bonded diamond or boron nitride particles and a base layer of cemented car-bide bonded, preferably under high temperatures and pressures, to the par-ticulate layer. The particulate layer is degradable by exposure to tempera-tures above a predetermined temperature. The substrate is bonded to the base layer of the compact with a filler metal which,to form a bond,requires the exposure of the surfaces to be bonded to a temperature substantially greater than the degradation temperature of the particulate layer. The com-ponent is fabricated by heating the base layer, filler metal and substrate to a temperature in excess of the degradation temperature while maintaining the temperature of the particulate layer below the degradation temperature via a heat sink.

Abstract: Abstract of the Disclosure A method for manufacturing a thin and flexible ribbon of superconductor material such as V3Sn, V3Ge, V3Si, Nb3Sn, Nb3Ge, Nb3Si and La-Au having a fine and compact microscopic structure comprises heating raw super-conductor material at a temperature within the range between its melting point and 300°C above the melting point to form a melt having suitable wettability and viscosity; ejecting the melt through a nozzle under a pressure within the range from 0.01 to 1.5 atm. against a cooling surface of a moving substrate such as a rotating drum; and cooling instantaneously and very rapidly a jet flow of the melt on the cooling surface at a cooling rate of 1,000°C to 1,000,000°C/sec. In order to manufacture the thin elongated ribbon of excellent configuration it is preferable to effect the cooling in a reduced atmosphere.  The invention also provides the thin and flexible ribbon processed by the above mentioned process.  When an intermetallic compound such as Nb-Si, Nb-Sn, Nb-Ge, V-Si, V-Sn and V-Ge is used as the raw superconductor material a thin and flexible ribbon of superconductor material having essentially a crystalline structure is formed.  When La1-x(AuyCu1-y)x, wherein x>0.9, O?y?1 is used as the raw superconductor material it is possible to obtain a thin and flexible ribbon of super-conductor material having essentially an amorphous structure.

Abstract: ABSTRACT OF THE DISCLOSURE   The invention provides a process for the liquefaction of coal.  The comminuted coal is slurried in a solvent or pasting oil and digested, normally under hydrogen pressure, e.g. of 50 to 250 atmospheres partial pressure, under cata-lytic conditions, at temperatures between about 380 and 500°C, preferably 400 to 470°C and residence times between about 10 and 100 minutes.  The solvent or pasting oil is obtained wholly or mostly by recycling from the distilled fractionation of the reaction products.  The solvents system comprises a light fraction in the boiling range up to 200°C and a heavy residue fraction, boiling mainly above 450°C, there being a more or less well-defined lack of solvent in a boiling range intermediate between 200 and 450°C.  Pre-ferably less than 20%, e.g. 5% or less of the solvent sys-tem boils between 200 and 450°C.  The ratio of low boiling to high boiling solvent is preferably from about 3:1 to 1:3. The process can be controlled so that the coal is converted virtually completely into distillable products, more par-ticularly predominantly in the crude diesel fuel range (200 to 450°C).  Optionally fractionating residue may be recovered as a further valuable product for making excep-tionally high grade electrodes by delayed coking at 500°C followed by graphitisation at 1400°C.

Granted: 1982-08-17
Abstract: ABSTRACT OF THE DISCLOSURE        An improved process is provided for producing chlo-rine and iron oxide in a fluidized-bed reactor by treating ferric chloride in the vapor phase with an excess of oxygen at a temperature of 550 to 800°C in the presence of a catalyst made from sodium chloride and iron oxide.  A carbonaceous fuel is fed to the reactor bed to supply supplemental heat.  The improvement comprises using a fluidized-bed reactor in which a portion of the bed material is continuously recycled and the carbonaceous fuel is supplied in a pulverized solid form in an amount equal to between 1 and 9 percent of the weight of the iron chloride fed.  The fuel has a stable ignition tempera-ture in air of no higher than 500°C and contains hydrogen amounting to between 0.5 and 2.5 percent by weight of the fuel.      The process is particularly useful for avoiding potential pollution problems associated with the disposal of iron chlo-ride by-product from ilmenite chlorination processes while recovering valuable chlorine.

Abstract: SUBMERGED PILE GROUTING            ABSTRACT OF THE DISCLOSURE    Apparatus and method is disclosed for filling the annulus between the jacket and piling of members of cluster or pin piles with fluid grouting material.      Cluster or pin piles surround and support a main leg can of an offshore rig.  The main leg extends to the water surface and supports the platform of the rig.          The cluster or pin piles terminate below the water surface.  Each cluster or pin pile includes a hollow, cylindrically shaped jacket with a piling through it.          A dual packer, comprising two, vertically separated packers is used to seal the jacket of the cluster or pin pile to the piling.  An annular chamber is formed between the two packers.  Dual lines provide fluid flow communication between the annular chamber and apparatus located at the water surface.  The apparatus at the water surface uses the dual lines to exhaust water from the annular chamber and set the packers.  These dual lines also are used by the apparatus to test the integ-rity of the seal of the packers with the jacket and the piling, and fill the annular chamber with liquid grout-ing material, including when either of the packers does not form a seal with the piling or the jacket.  The dual lines are additionally used to apply pressure to the fluid grouting material to aid in forming a bond between the fluid grouting material and the jacket and the piling.  The method includes the steps of:     (a) setting the dual packer;    (b) introducing air to expel water from the annular chamber;    (c) testing the annular chamber to determine the integrity of the seal of the dual packer with the piling and the jacket;    (d) filling the annular chamber with fluid grouting material; and (e) applying pressure to the fluid grouting material to aid in forming a bond between the fluid grouting mater-ial and the jacket and the piling.

Abstract: Abstract Of The Disclosure Lift apparatus is adapted for raising and lowering portable grain elevators and the like and includes both a power lift mechanism and an alternative manual lift mechan-ism.  It also includes an upper limit stop for limiting the height to which the power lift mechanism can raise the elevator and a tie-down limit stop for tying the raised end of the elevator to an anchoring object for safety in addi-tion to prohibiting the power lift mechanism from operat-ing when the elevator is so anchored.  In the disclosed embodiment, an elevator lift apparatus which includes a cable for drawing a front frame member toward a rear frame member to effect raising the rear end of a grain elevator is provided on one end with a power driven winch for drawing the cable to effect lifting, and it is also provided on its opposite end with a manual winch for also drawing the cable to effect lifting.  A hydraulic fluid flow circuit is provided to supply the hydraulic motor with fluid, said circuit having an alternative one-way directional flow route for bypassing the hydraul-ic motor on the power lift mechanism.  An upper limit stop means which is mechanically sensitive to the position of the lifting apparatus at the desired maximum limit of lifting range for actuating said valve to bypass the flow of hydraulic fluid around the hydraulic motor.  A second alternative circuit is also provided to allow hydraulic fluid to flow in a reverse direction through the hydraulic motor to begin lowering the elevator to a position in which the valve is deactuated, restoring the system to the normal fluid flow route.  The tie-down mechanism is also connected to the valve and has enough travel to actuate the valve to bypass the motor but is limited in travel such that the anchoring force is transferred to the upper end of the elevator for tie-down purposes.  Alternative embodiments include free hanging weighted bodies to sense the maximum desired height to which the elevator is raised and to actuate the bypass valve mechanism.
