Abstract: The invention relates to a method of production of ultradispersed diamond which can be used for the production of abrasive materials, more particularly, this method relates to production of fine diamond powder by explosive means.

Abstract: A hydrometallurgical process for the recovery of one or more metal values from a metal ore material in the presence of clays and/or fines material, said ore material being comprised of one or more metal values and a matrix material having a sulfur content wherein the sulfur is present in an oxidation-reduction state of zero or less. The process comprises forming particulates from particles of said ore material, particles comprising said clays and/or fines material, an acid-resistant polymeric agglomeration aid and an inoculate comprising bacteria capable of at least partially oxidizing the sulfur content; forming a heap of said particulates; biooxidizing the sulfur content and recovering those one or more metal values.

Abstract: A process for biooxidation of sulfides in a heap of mineral ores by freeing precious metals dispersed or occluded within said ores as pyritic or arsenopyritic sulfides and the like; the process comprises forming particulates from ore particles with an inoculate comprising bacteria capable of attacking, by biooxidation, sulfides and/or elemental sulfur in said ore particles; from these particulates a heap is constructed; and the biooxidation takes place in such heap by adding to or dispersing within the heap a leaching solution, circulating the leaching solution within the heap and recovering the precious metal values from the heap; recovery may be accomplished with a cyanide, thiourea, or a thiosulfate lixiviant.

Abstract: A method is provided for the recovery of precious metal values, such as gold and silver, from refractory carbonaceous, or carbonaceous-sulfidic ore material. The ore material is inoculated using a specific microbial consortium and then incubated to deactivate the carbonaceous component of the material to prevent binding of the precious metal values to the carbonaceous component. The precious metal is then recovered.

Abstract: A gyratory mantle liner assembly for use in a gyratory crushing machine including a mainshaft to which is attached a retaining ring having a lip, a conical-shaped upper liner having a serrated and bevelled lower edge, a plurality of lower liner segments and having an upper bevelled edge arranged around the lower circumference of the mainshaft, and a retaining nut for tightening and applying constant force to the upper and lower liner segments to hold them securely against the mainshaft. The lower liner segments defining the crushing surface are generally made of heat treated alloy material.

Abstract: An apparatus for controlling the rate of deceleration of a moving body. The apparatus has a cable or net for engaging a moving body and tape connected to the cable or net. The tape is wound onto a reel at the start of a deceleration and is unwindable from the reel during the deceleration so that unwinding the tape from the reel causes a corresponding rotation of the reel. A pump is operatively connected to the reel so that rotation of the reel causes pumping of a hydraulic fluid at a rate which increases as the rate of rotation of the reel increases. A control valve disposed across the discharge of the pump varies pressure drop across the control valve. A brake is provided for applying a braking force to the reel, and an actuator is provided for varying the braking force applied by the braking means in response to the pressure drop.

Abstract: An elemental net for a multiple element aircraft arresting net system. The elemental net has a single upper horizontal strap, several vertical straps having top ends and bottom ends, and at least two lower horizontal straps. The top ends of the vertical straps are directly affixed to the upper horizontal strap at spaced intervals along the upper horizontal strap. The bottom ends of the vertical straps are alternatingly affixed to one of the lower horizontal straps so that the lower horizontal straps are free to move relative to each other to a significant degree and so that lifting of one vertical strap will tend to lift only one of the lower horizontal straps in the vicinity of the vertical strap being lifted. The present invention provides a variable window which is free to expand or contract during aircraft engagement, permitting easier penetration of the net by a greater mix of aircraft.

Abstract: An improved coupling for connecting an arresting pendant and the woven tape utilized in an aircraft arresting system is provided. The coupling consists of an elongated hollow body having at least one open end and a longitudinal slot which extends into its hollow interior. A mounting bracket for connection of the coupling to the arresting system pendant is attached to the side of the coupling body which is opposite from the slot. The tape from the arresting system is wrapped between and around a plurality of clamping bars and is then inserted through an open end of the coupling body with the connected end of the tape extending through the longitudinal slot. The clamping bars are sized and shaped to substantially fill the interior of the coupling body and to grip to the tape which is wrapped then around.

Abstract: A multiple stake anchoring system for portable aircraft arresting gear including a stake guide for directing a first stake into the ground at a predetermined angle, a stake driven into the ground through the stake guide, a spacer collar mounted on the stake guide by sliding over the top of the stake, and a rigid elongated stake tie having parallel cylindrical passages through each of its ends mounted on the spacer collar by sliding one passage thereof over the stake. A second stake is driven into the ground through the cylindrical passage in the distal end of the stake tie. The second stake is rigidly connected to the first stake by the stake tie and has the same angle of inclination with respect to the plane of the ground because the two cylindrical passages through the stake tie are parallel.

Abstract: A lubricant distribution system for refrigeration units having a plurality of parallel compressors which system maintains the proper level of lubricant in the compressors during operation. The system comprises compressor suction inlet lines which connect each of the compressors of the system with a common suction header located at an elevation below the suction inlets on the compressors. The common suction header is connected to the evaporator outlet by a conduit which extends from the evaporator to the common suction header. The compressors suction inlet lines are sized to provide a suction gas mass velocity therethrough which is sufficient to carry lubricant into the compressors as an entrained liquid even when the compressors are operating at partial capacity.
