Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method of processing ore of the type which includes the steps of grinding the ore, classification of the ore and concentration of the ore, the classification step following the step of grinding by preceding the step of concentration.   According to the invention, the step of classification is of the type of a method wherein ore particles are generally simultaneously classified into fractions different from each other with respect to both size and density of the particles.  The advance in the art is in that valuable, relatively heavy particles can be brought to the step of concentration in a relatively coarse state to thus reduce the cost of said step of grinding, whereby the efficiency and economy of the overall method is improved.

Abstract: LIQUID CHROMATOGRAPHY PUMPING SYSTEM WITH COMPENSATION MEANS FOR LIQUID COMPRESSIBILITY                    Abstract of Disclosure In a liquid chromatography system including a chromatographic column, a reservoir for a slightly compressible liquid mobile phase, piston means cooperating with the reservoir for pumping the liquid phase through the chromatographic column, and means for displacing the piston at a pre-selected velocity, an improvement is disclosed enabling maintenance of a constant flow in the presence flow resistance changes at the chromatographic column. Such resistance changes may arise, for example, in cosequence of viscosity  changes occurring in the liquid phase during the course of gradient elution operation.          According to the improvement, pressure control means are provided in the  flow path between the reservoir and column, the said means being adapted for maintaining a substantially constant pressure at the reservoir.   In consequence flow rate changes arising from expansion or contraction of the liquid phase in consequence of compressibility, are precluded.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of and apparatus for recovering information from a record medium of the type wherein the information is modulated onto a carrier and recorded in one portion of the record medium and the carrier is recorded in another portion of the record medium.  The modulated information is reproduced from the record medium while the medium is rotated, and simul-taneously, the carrier also is reproduced from the medium. The reproduced modulated information then is demodulated with the reproduced carrier to recover the original signal informa-tion.  In one embodiment, the recorded information is a composite color television signal and the carrier constitutes the chromi-nance subcarrier for the color television signal.          Also disclosed is a method and apparatus for recording signal information on a rotatable record medium.  A reference signal is provided and is recorded in a circular track on the record medium.  Signal information also is provided and is modu-lated onto the reference signal, the modulated signalinformation then being recorded in a separate portion of the record medium. In one embodiment, the reference signal upon which the signal information is modulated is the previously recorded reference signal that has been played back from the record medium.  The signal information may comprise color video signal components and the reference signal may comprise one or more subcarriers for the color video signal components.  Preferably, the color video components which are modulated onto the subcarriers are combined with a luminance signal and recorded as a composite color television signal.

Abstract: GRADED REFRACTIVE INDEX OPTICAL FIBER            ABSTRACT OF THE DISCLOSURE           A multimode optical fiber waveguide comprising a central core layer having a refractive index decreasing continuously in the radial direction from its center, and a second layer having a uniform refractive index lower than the lowest refractive index of the core.  Mode coupling is achieved by introducing carefully designed fluctuations into the fiber core, while radiation  losses due to such mode coupling are minimized by the abrupt index discontinuity in the refractive index.  In one illustrative embodiment, mode filters spaced at certain intervals along the waveguide are used to suppress the buildup of power in predetermined modes.          In another illustrative embodiment, the refractive index of the fiber is such that mode filtering is achieved continuously over its entire length thereby avoiding the use of discrete mode filters.

Abstract: STACKED BLADE MATRIX PRINTER HEADS      Abstract of the Disclosure A printer head for use in an impact printer of the dot-matrix type utilizes a stack of pivoted thin blades, each having a printing tip at one end thereof.  A pancake coil is attached to each blade for initiating selective independent movement thereof within a common, externally-produced magnetic field to efficiently convert electrical print signals to kinetic energy in each printing of vertical array thereof thereby facilitating printing of symbols, characters and other indicia on underlying media with high resolution.  The single magnetic-field-producing means interacts with all pancake coils of the stack of printer blades to facilitate close spacing of the printing tips for superior character printing.  Resilient members are integrally formed in each blade to support the moving structure with negligible loss, thereby increasing the printing speed of the stacked blade head.

Hydraulic rams asso-ciated with roof-supporting and anchoring means are pro-vided for sumping the cutting heads.  A curtain assembly or the like contains the dust generated during cutting to a confined area adjacent the cutting face, and an ex-haust fan or fans continuously draws the dust away from the confined area.  Portions of the roof supports extend into the confined area in order to provide maximum sup-port for the roof during cutting.

Abstract: ABSTRACT OF THE DISCLOSURE             A machine is disclosed for forming a sleeve of a shrinkable, cellular polymeric material from a pre-decorated web.  The web is processed to provide (1) a partial-depth slit along the longitudinal dimension, and (2) cross-dimension pleats.  Pre-decorated shrunken neck labels are formed from the web for overlying the neck and closure of the bottle and including a pilfer-proof feature.  Such a label is formed from the processed web by cutting the blank having the cross pleats therein and winding the blank on a mandrel to overlap the ends and seam, the overlap to make a sleeve.          A rotary mandrel mechanism is provided with a vacuum at the periphery thereof to hold the label blank in place and the mechanism operates the mandrel to rotate it about its longitudinal axis for wrapping or winding the blank strip thereon.  The mandrel includes a hot air nozzle system for heat welding or bonding the overlapped ends of the blank on the mandrel.  Hot air is furnished by the nozzle which extends the length of the overlapping seam of the blank at a time just before the opposite ends, the leading and trailing ends of the blank, are about to overly one another.  The heat is sufficient upon engagement of the overlap portions to join or heat seal the material at a side seam and form a sleeve.  The sleeve is stripped onto the top neck end and over the closure of a bottle and shrunken to a snug fit.
