Abstract: ABSTRACT OF THE DISCLOSURE       Method and apparatus for subterranean slurry drilling and mining of granular ore, such as phosphates, with a combined drilling and mining apparatus.  The apparatus includes a tool string having a drilling head and mining head that are selectively interchangeable on its upper end for drilling into one or more ore strata to be mined and thereafter to remoa ore from the strata as a slurry.  The drill string includes a plurality of inner and outer pipe sections connected to a mining nozzle section, to an educator pump section, and to a drill bit at its lower end.  A drill/mining liquid is directed through the tool string during both the drilling  and mining modes of operation.  During drilling, liquid is directed through a foot valve into the rotating bit to wash cuttings to the surface externally of the tool. During mining, the tool string is rotated, the foot valve is closed, and a mining nozzle is opened thereby causing liquid jetting from the mining nozzle to reduce the ore to a slurry.  The slurry is pumped to the surface by liquid passing upwardly through the educator pump and through the inner conduit.  Without removing the apparatus from the hole, a hydraulic control system is actuated by hydraulic pressure equal to or less than system pressure for shifting the mining nozzle, the educator nozzle, and the drill bit foot valve between a drilling mode and a mining mode thus enabling several different ore bearing strata to be mined.         In a modified form of the invention a plurality of vertically spaced mining nozzles are provided and each -1a-nozzle is aligned with a different ore strata.  A hydraulic control system is provided for controlling the hydraulic components between their drilling and mining modes, and for opening and closing the mining nozzles independently of each other.  The control system is responsive to pressure equal to or less than the system pressure.                        -1b-

Abstract: HEIGHT ADJUSTABLE CHAIR BASE                        ABSTRACT A rotatable and vertically adjustable chair base is disclosed comprising a floor engaging stand, an up standing tubular post mounted on the stand, a threaded member received by the tubular post and a smooth spindle slidably and rotatably received by the upstanding tubular post.  Internal threads are provided in the upstanding tubular post with a split sheet metal sleeve carrying stamped metal threads.  The stamped metal threads of the sheet metal sleeve are engaged by a plastic threaded member which takes advantage of the relatively low coefficient of friction between plastic and metal.  The spindle rides atop the threaded member, the vertical position of the spindle being determined by the position of the threaded member. Vertical adjustment of the spindle and the chair mounted atop the spindle is achieved with detent means for alter-nately engaging and disengaging the threaded member.  When the chair is unoccupied, the spindle engages the threaded member and is vertically adjustable by rotation of the chair.  Under the weight of an occupant the spindle auto-matically disengages from the threaded member to allow the occupied chair to freely rotate without vertical adjustment of the spindle.

Abstract: ABSTRACT:          CALCINATION METHOD AND APPARATUS     Minerals such as gypsum in powdered condition are calcined with increased thermal efficiency in a vessel having a lower region of small cross section by means of hot gas delivered by a downwardly extending tube directly into the lower region of the vessel.  The preferred vessel is an inverted cone (1) and has a lid (3) which is fitted with a mineral inlet (4) and exhaust outlet (5), and through which the hot gas tube (6) passes.  The hot gas may be produced in the tube by a burner (17).  Discharge from the vessel is preferably through an overflow weir (11) and an internal pro-tuberance (15) may be used to assist in distributing the gas flow across the bottom of the vessel to avoid accumulation of calcined material.

Abstract: ABSTRACT OF THE DISCLOSURE            Kraft or sulphate pulp is used in the unbleached state for the production of packaging material because of its good strength properties.  However, the unbleached Kraft or sulphate pulp is not suitable for packaging material for food since it has an ugly brown colour and an unpleasant odor due to the decom-position process and the washing with condensates from evapora-tion.  According to the invention, the Kraft or sulphate pulp may be brightend by approximately five points and deodorized by means of peroxide without reducing the strength.  The treatment can be carried out in conventional plants for the production of pulp after diffusion washing in a thick-pulp tower.  Hydrogen peroxide is preferably used as the peroxide.

Abstract: ABSTRACT OF THE DISCLOSURE         A semiconductor integrated circuit with a short turn-off time in which a high breakdown voltage semi-conductor element and a Schottky barrier diode are fabricated into a semiconductor substrate, is disclosed.          In the integrated circuit, within a semiconductor substrate of a first conductivity type, a diffusion layer with a low impurity concentration disposed deeply which is used as one layer of a high breakdown voltage semiconductor element formed by a high breakdown voltage process and a diffusion layer with a high impurity concentration disposed more shallowly than the diffusion layer with a low impurity concentration, are formed so as to partially couple with each other.  The diffusion layer with the high impurity concentration is used for both the ohmic contact for the electrode of the diffusion layer with the low impurity concentration and for a guard ring for a Schottky barrier diode.  With such a construc-tion, a Schottky barrier diode may be assembled into a high breakdown voltage semiconductor element with a minimum increase of area.  Accordingly, the semiconductor integrated circuit obtained has a high degree of integra-tion and a short turn-off time.

These compounds have the structural formula:                                           .        Each R independently is a hydrocarbyl or inertly substi-tuted hydrocarbyl, X is a phenoxide anion and m is the valence of the anion X.  The phenoxide anion X is a conjugate base of a polyhydric  phenol bearing from 2 to 6 nuclear hydroxyl groups and having from 6 to 30 carbon atoms.  These phosphonium phenoxide salts optionally may be complexed with a polyhydric phenol or with the tetra-hydrocarbyl phosphonium hydroxide salt.  The compounds of this invention are suitable as catalysts for reacting vicinal epoxy groups with phenols, carboxylic acids and carboxylic anhydrides.  These compounds are also suitable for preparing precatalyzed epoxy resins and precatalyzed polyhydric phenols.  When these compounds are employed as catalysts in the advancement reaction of the diglycidyl ether of bisphenol A with bisphenol A, epoxy resins having weight average molecular weights over 100,000 units have been demonstrated. 28,155-F

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a method for the preparation of a homogeneous, physically stable colloidal elemental iron dispersion of colloidal iron particles having a size in the range of from about 10 Angstrom units to about 200 Angstrom units. The method comprises preparing a solution of an active polymer in an inert solvent, and incrementally adding thereto an iron precursor, at a temperature at which the iron precursor will become bound to the active polymer and thermally decompose to produce elemental iron particles, the process being carried out in an inert atmosphere. Such dispersions may be used per se as catalysts, or may be used for the preparation of supported colloidal iron catalysts. The dispersions may also be used for the preparation of ablative optical recording media, and for the preparation of magnetic xerographic developer materials.
