Abstract: A method for treating a medical condition of a patient with Alpha-2 Macroglobulin (?2M) molecules in an allogeneic or xenogeneic manner, the method includes: drawing whole blood from a donor, separating plasma containing ?2M molecules from other components of the whole blood; isolating the ?2M molecules from the other components of the plasma; and administering at least some of the isolated ?2M molecules to the patient via injection or inhalation, wherein the donor and the patient are different individuals.

Abstract: A method includes: depositing whole blood into at least one separator tube; subjecting the at least one separator tube to a first centrifugal force to cause a combination of the first centrifugal force and separator gel within each separator tube of the at least one separator tube to separate plasma of the whole blood from red and white blood cells of the whole blood within the at least one separator tube, wherein the plasma includes ?2M molecules; transferring one or more portions of the plasma from within the at least one separator tube and into at least one isolator; and subjecting the at least one isolator to a second centrifugal force to cause a combination of the second centrifugal force and a filter within each isolator of the at least one isolator to isolate the ?2M molecules from other components of the plasma within the at least one isolator.

Abstract: An improvement in the screen circumscribing or partially circumscribing the rim of an agitation tank is disclosed. A screen substantially impermeable to the charcoal is provided which is inclined inwardly at an angle between about 35.degree. and 55.degree. from vertical. The metal-bearing charcoal adhering to the screen is readily washed from the screen by the rolling motion of the mixture in the tank.

Abstract: An improved housing embedded in the ground for use in crushing of ore. The housing has a generally figure eight configuration in plan defined by a pair of hollow, upright cylindrical segments with a common wall between the points of intersection of the segments. One segment houses a dump pocket, an ore crusher, a surge chamber and a discharge feeder and conveyor in descending order, and the other segment contains drive machinery, dust control apparatus, a lubrication system, hoist ways, elevator shaft, and other service facilities. The crusher in the first segment is supported on a floor supported by the wall of the first segment itself. The housing requires only a minimum of concrete and reinforcing steel since the cylindrical configuration of the sections thereof provide the most efficient resistance to lateral pressures resulting from earth backfill and surcharge from heavy haul trucks.
