Title: Hydrometallurgical process for the treatment of copper-bearing ore
Inventor: ALVAREZ ALIRO TEODORO NELSON P
IPC: C22B15/00
Filed: 1992-12-18
Granted: 1999-05-25
Abstract: A hydrometallurgical process for recovering copper from copper bearing ores or fractions, by a process of first wetting and sulfatizing the ore with controlled amounts of H2SO4 and water, followed by acid curing and repulping to sulfatize a substantial portion of the copper in the ore.  Also, the fine and coarse fractions can be classified, followed by pile leaching the coarse fraction, preferably reusing the cycled H2SO4 solution obtained during the copper recovery process.  Since the coarse fraction is classified from the fine fraction, the pile leaching process is performed at very high specific flows, which substantially reduces the leaching period as compared with that of conventional pile leaching.

Granted: 2000-10-17
Abstract: A spinal implant (10) that has a rod (40) that connects and stabilizes the vertebrae of a vertebral column. The implant (10) has screws (16) that are attached to the vertebrae. Each screw (16) has a clamp (26) with a first bore (28) that allows the clamp (26) to be placed over the screw (16). The first bore (28) of the clamp (26) is larger than the major diameter of the screw (16), so that the clamp (26) can float about the Screws (16). The clamps (26) each have a second bore (34) perpendicular to the first bore (28), adapted to receive and hold the rod (40). Integrally formed with the second bore (34) of each clamp (26) are a pair of flanges (46, 48). When the flanges (46, 48) are deflected inward, the clamp (26) "grabs"  the rod (40). The clamp (26) is placed on a hexagonally shaped shoulder (64) of the screw ( 16). A nut (50a) is fastened onto the opposite side of the clamp, such that the flanges (46, 48) are pressed between the shoulder (60) and the nut (50a). The diameter of the second bore (34) and rod (40) are approximately the same so that a small deflection of the flanges (46, 48) produces a large clamping force on the rod (40).

Title: Linkage device for mounting swather header
Inventor: HONEY GREGORY J
IPC: A01D43/04
Filed: 1995-01-03
Granted: 2002-11-12
Abstract: A levelling mechanism for use in a lift system of a windrowing machine of the type including a tractor unit and a swather header to permit the use of a grain header which is held suspended above the ground rather than a hay type swather header which normally engages the ground during cutting. The type of lift systems used in some known hay windrowers include a pair of lift assemblies each of which has a single action lift cylinder. The two cylinders are supplied from a common supply line, and because the moving lift components of the two assemblies are individually activated by their respective cylinders the suspended grain header does not remain levelled under certain conditions, such as if there is a build up of greater crop weight at one end relative to the other. The present levelling mechanism includes a torsion bar carried at the front of the tractor unit, the torsion bar having radial arms at opposite ends which are connected to the moving component of the adjacent lift assembly so as to resist movement of the moving components out of unison, thus keeping the head level under normal cutting conditions.

Patent CA-2145886-C (CA)
Inventor: RICHARDSON WILLIAM H JR
IPC: C10J3/06
Filed: 1995-03-30
Granted: 1999-06-15
Abstract: Means and method of generating electrical power by combusting a fuel gas in an internal-combustion engine and so doing useful work, such as driving an electrical generator, while virtually eliminating the harmful emissions characteristic of fossil fuel combustion.  The fuel is evolved in gaseous form by high-temperature conversion of carbon and water, as in an underwater arc provided with carbon and lacking hydrocarbons.  The gaseous fuel is non-self-combustible, but is readily combustible in the presence of air.   Its composition is imperfectly understood,  but it appears equivalent to hydrogen in major amount and carbon oxides  (mainly monoxide)  in minor amount. Its combustion products are essentially carbon dioxide and water.

Title: Topoisomerase ii inhibitors and therapeutic uses therefor
Inventor: POMMIER YVES
IPC: C07D491/048
Filed: 1993-10-14
Granted: 2006-12-12
Abstract: Azatoxin and derivatives thereof of formulae B-D are illustrative of a new class of antitumor drugs that are topoisomerase II (top 2) inhibitors. The pharmacophore inhibits the catalytic activity of the purified enzyme but does not unwind relaxed or supercoiled DNA. It is nonintercalative and has at least two domains: a quasi-planar polycyclic ring system, which may bind between DNA base pairs, and a pendant substituent thought to interact with the enzyme, with the DNA grooves or with both. In SV40 and C-myc DNA, azatoxin induces numerous double-strand breaks according to a cleavage pattern which differs from those of known top (2) inhibitors. Azatoxin also is a potent inhibitor of tubulin polymerization.

Title: Two-phase tooth implant
Inventor: MOSER WALTER
IPC: A61C8/00
Filed: 1995-10-16
Granted: 2007-06-19
Abstract: Mechanical joining of a two-phase tooth implant, consisting of two components which are joined by means of a conical pin (11) projecting into a conical sleeve (7), the cone pairing being realized within the self-locking region and the cone pin being penetrated by a centrally aligned, tension screw reduced diameter which tensions the pair of cones against each other. The design permits the two implant components in a two-phase tooth implant to be steplessly positioned in the circumferential direction and to be joined in an anti-rotation, gap-free joint. The required degree of miniaturisation, with a sufficient component strength, is achieved through the use of a cone combination in the self-locking region and through a of the tension screw in the region of the cone joint. By these means, the mechanical, aesthetic and hygienic requirements for a two-phase tooth implant are better fulfilled than in the case of the known designs.
