Title: Method and apparatus for beneficiating ores
Inventor: MACKIE DANIEL A
IPC: C22B1/00
Filed: 1988-11-21
Granted: 1993-03-09
Abstract: ABSTRACT          A method and apparatus for treating mineral-bearing ores and, more particularly, for treating ores containing precious metals, base metals and the like values by providing a means to extract the metal or other values from a particulated ore by classifying the ore to separate values from the gangue, and by continuously chemically leaching the said values from the ore.  In accordance with an embodiment of the invention, particulated ore is fluidized and intermittently moved through a tank to classify the ore particles into strata according to size, shape and density to beneficiate values, either heavier or lighter than the gangue, for recovery of concentrated values.  In accordance with another embodiment of the present invention, crushed or ground ore is moved through a vat leaching jig in such a manner as to cause the heavier metal-laden or other values-laden particles or larger particles to differentially settle to the bottom of the apparatus, which can then be extracted separately and wholly from the finer values such as gold or precious metal particles which may be chemically leached from the ore and recovered from the lixiviant.

Abstract: ABSTRACT     This invention relates to a cooling and heating system which operates on the absorption and phase change heat exchange principle.   More particularly it relates to a continuous heat actuated, air cooled, double effect generator cycle, absorption system.  In further aspects, this invention relates to a system constructed for use with an absorption refrigeration solution pair consisting of a nonvolatile absorbent and a highly volatile refrigerant which is highly soluble in the absorbent.  A disclosed refrigerant pair are ammonia as the refrigerant and sodium thiocyanate as the absorbent.   System efficiency is improved when heat and externally  supplied  mechanical  energy  is  combined  and converted to pressure energy that is applied to or removed from  the  solution  pair.    The  invention  includes  the conversion of such pressure energy to mechanical energy and the replacement or supplementing of externally supplied mechanical energy with converted mechanical energy.

Abstract: An integral disposable absorbent article such as a diaper having a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, at least one elastically contractible gasketing cuff, and at least one barrier cuff. The barrier cuff has a proximal edge and a distal edge. The absorbent article is additionally provided with spacing means for spacing the distal edge away from the top surface of the topsheet. In addition, adhesive means secure the end portions of the barrier cuff closed. A channel is formed between the proximal and distal edges in at least the crotch region because the distal edge is spaced away from the topsheet top surface.      When the diaper embodiment of the present invention is applied to a wearer, the barrier cuff rides up along the inner thighs and the perineum of the wearer in the crotch region and along the buttocks in the back waist region. Leakage prevention is enhanced because body exudates which are not immediately absorbed by the absorbent core contact the barrier cuff and are contained and held within the channel so that they do not wick out of the diaper or flow out of the gaps between the diaper and the legs or waist of the wearer. Additionally, should such exudates flow beyond the barrier cuff, leakage prevention is further enhanced by the gasketing cuff because it forms an additional fluid impervious barrier about the leg or waist of the wearer.

Abstract: A method of producing endless drive belts of natural or synthetic rubber with thread-shaped embedded strength carriers which preferably extend in the longitudinal direction. This method relates especially to multiple V-belts and similar belts having longitudinal ribs extending continuously over the inner periphery or circumference thereof. A raw belt member is built up in upside-down sequence of layering, and is placed into an outer form or mold, in which it is formed-out and vulcanized. The belts are then turned or folded or rolled over into the use condition thereof. The raw belt member, which is produced oversize with respect to the outer form or mold, is retracted, pulled-in, or drawn-in to an outer diameter corresponding to the smallest inner diameter of the outer form, and is expanded within the outer form to, or essentially to, the original outer diameter thereof. The raw belt member may be subjected to a pressure gradient, drop or differential effective from the outside toward the inside for retracting, pulling-in or drawing-in the diameter thereof. The raw belt member has strength carriers of synthetic polymers which shrink in the heat, and may be subjected to an elevated temperature for retracting, pulling-in or drawing-in the diameter thereof.
