Abstract: ABSTRACT     Gold or any desired mineral treated to have a lyophilic surface, is recovered from ore bodies by an agglomeration method in which coal and oil are added to the ground or slurry and contacted in a zone where any agglomerates are kept below 500 microns in size.   Subsequently the mix is passed to an agglomeration zone where agglomerates of coal oil and gold or the lyophilic mineral are formed.   The agglomerates are separated from the gangue and recycled to the contacting zone until a desired gold or mineral concentration in the agglomer-ates is achieved.

Abstract: AUTOMATIC PARTICLE-SIZE ANALYZER ABSTRACT OF THE DISCLOSURE The invention is apparatus which can automatically make a screen analysis of a granular material. The heart of the apparatus is a polygonal drum having graded screens on each of the faces except one. This open face serves as a means for introducing a sample into the interior of the drum and for discharging any material larger than the largest screen. A gear motor and crank arrangement serves to longitudinally shake the drum and agitate the sample. A second gear motor indexes the drum from screen to screen after a predetermined shaking time. Each screen fraction is accumulated on an electronic scale with weights being determined by differential weighing. The gear motors are timed by a microprocessor which also receives screen fraction weight inputs and calculates a screen analysis.

Abstract: ABSTRACT   A torsional vibration isolator coupling displaying particular utility in automotive vehicles powered by internal combustion engines of the diesel or otto type.  An input torque shaft having undesirable torsional vibrations, such as a torque directly derived from an internal combustion engine, is coupled to an input torque disc.  The periphery of the input torque disc is coupled by an elastomer member and an intermediate rigid disc member to the periphery of a torque output disc, the periphery of the latter also carrying an elastomer member.  The two torque discs are parallel and coaxial.  A torque output shaft is carried by the torque output disc.  A rigid cylindrical retainer axially clamps and axially compresses the elastomer members against their sandwiched torque discs. The output torque is substantially free of torsional vibrations, thus extending the life of power brake, power steering, and the like units driven by the torque output shaft.

Abstract: NON-SPINNING TASK LOCKING                       USING COMPARE AND SWAP                         ABSTRACT OF THE DISCLOSURE      A method  or controlling both shared and exclusive access for a resource in a multiprocessor system wherein a first-in/first-out queue is formed for tasks suspended while awaiting access and wherein access to the resource provides that control of access required for manipulation of the first-in/first-out queue which is not provided by the atomic nature of compare (double) and swap.  Each member of the queue has indicators of the access it requested and of the next most recently enqueued member which has a corresponding indicator.  A lockword is established having two parts, a lock flag indicating the status of the resource, whether available, under shared ownership or under exclusive ownership and a lock pointer pointing to the most recently enqueued task.  In requesting or releasing access, an initial guess is made as to the value of the lockword and a projected lockword is calculated based on the guess.  Then an atomic reference is made to the lockword during which no other multiprocessor has access to the lockword.  During the atomic reference, the lockword is compared to the guess of the lockword and if the guess is correct, the lockword is replaced by the projected lockword which rearranges the queue for the requesting or releasing task.  If the guess was incorrect, the value of the lockword is used to calculate another projected lockword.  If another task can affect the next tasks to gain access, the process with the atomic reference is repeated until no intervening changes occur between atomic references.

Abstract: ABSTRACT   A low cost injection-molded plastic pin grid array chip carrier is provided as en alternative to a ceramic pin grid array chip carrier, in which an electrically superior package is- fabricated by supporting nested lead frames in the mold cavity at the centers of the lead frames through the provision of a central carrier foreach of the nested lead frames, with the central carrier permitting a one shot molding proeess. In one embodiment the lead frames include square toroidal central carriers, with one set of nested lead frames being provided with offset leads such that all leads lie in the same plane in the package. Path resistance is lower than the ceramic pin grid array chip carrier because of the use of a copper lead frame as opposed to the sputtered tungsten used in ceramic packages. Interlead resistance is increased through the utilization of conical or pyramidal supports for the pins which lengthens the resistance paths between the leads Dueto the lower dielectric constant of plastic, the interlead capacitance is signifi-cantly reduced to permit higher speed operation and reduced cross-talk. The subject plastic pin grid array chip carrier is also electrically superior to a conventional glass epoxy package and can be produced at a fraction of the cost.

Abstract: KEY OPERATED ELECTRONIC LOCK                 ABSTRACT OF DISCLOSURE         A special type of key is made use of to actuate an electronically triggered release mechanism to unlock a door.  To enable the electronic means to function, inser-tion of the key in the keyway initially closes a switch to energize the electronic cirucit.  Also when the key reaches the switch closing position, a read head for the electro-nic circuity, located adjacent the keyway, interprets mag-netic coding carried by the key.  The electronic circuit is programmed to motivate a motor driven mechanism to move a locking pin out of engagement with a latch bolt where the latch bolt has been acting to hold a door locked. Once the locking pin has been removed, the latch bolt is in fact withdrawn from its locked position by rotation of the key in a substantially normal fashion.
