Granted: 1999-03-02
Abstract: A hydrometallurgical process is described for recovery of precious metals from ores refractory to treatment by lixiviating agents by crushing the ore to no finer than a nominal 1/4 inch (0.64 cm) size, acidifying the ore with a mineral acid, treating the ore to a preliminary oxidation with nitric acid, optionally adding a binder to the oxidized ore, heap treating the ore with nitric acid to complete oxidation of the ore, water washing the heaped ore, optionally increasing the alkalinity of the heaped ore, heap treating the ore with a lixiviating solution and recovering precious metals from the lixiviating solution. The process recovers NO x gases generated during the preliminary oxidation and binder addition stage for conversion into nitric acid which is recycled for treating ore. Chemical treatments in the process can be carried out at ambient temperatures and atmospheric pressures.
Patent CA-2102841-C (CA)
Inventor: IMMEL DARRYL R
IPC: E02F3/60

Granted: 1996-05-14
Abstract: The disclosure involves a bucket arch, used on dragline buckets, which has a pair of side sections and an arch center section disposed therebetween.  At least one lug is attached to the arch center section and exerts a force on the center section along a force axis.  In the improvement, the center section is angled with respect to the side sections and has an axis generally coincident with the force axis.  Such angled center section at least greatly reduces the twisting forces imposed on the arch by the lug.  Such center section also greatly reduces the wear or friction on the center section of the arch resulting from the drag chain rubbing thereon during tipping of the bucket.

Title: Vacuum filtration system and method of filtering pulp fibers from pulp slurry using the same
Inventor: EMPIE LEWIS F
IPC: B01D33/09
Filed: 1993-10-28
Granted: 1998-09-15
Abstract: A method and apparatus for filtering pulp fibers from a pulp slurry, using a combination of vacuum, hydrodynamic and hydrostatic forces in order to achieve a more effective deposition of pulp fibers onto the filter surface and enhanced flow of filtrate through the cylinder.  The apparatus is in the form of an improved vacuum filtration system, in which the filtrate outlet tube is disposed along the axis of rotation of the rotary cylinder and the filtrate inlet and outlet ports of each filtrate conduct are radially offset from one another in the direction of intended rotation of the cylinder.  During various phases of filter operation, vacuum forces generated by the vacuum source cooperate with either hydrodynamically or hydrostatically generated forces, which together act upon columns of filtrate in the filtrate conduits as the cylinder rotates.

Filed: 1994-11-24
Granted: 1998-11-17
Abstract: A method and device for reeling a paper or board web in a drum reel-up or equivalent, in which, when a paper or board reel formed on a reel spool situated in a reeling position becomes complete, a new reel spool is brought by transfer members into a stand-by position and accelerated up to the web speed.  The reel spool with the complete reel is transferred into an exchange position apart from the reel drum and the new, initially accelerated reel spool is transferred into the reeling position.  When the reel spool with its reel is transferred into the exchange position apart from the reel drum, the belt guide roll is transferred into nip-defining relationship with the complete reel that is being formed onto the reel spool and is displaced along with the reel spool into the exchange position so that the web runs during the entire exchange on support of the belt and through a nip between the guide roll and the reel spool.   The device includes a reel drum, a reel spool whereby the web runs through the nip between the reel drum and the reel spool onto the reel spool, a transfer device for bringing a new reel spool into nip-defining relationship with the reel drum after the paper or board reel on the first reel spool has become complete, and means for transferring the belt guide roll together with the reel spool into the exchange position so that, during the entire exchange, the web is supported on the belt and runs through the nip between the guide roll and the reel spool.

Granted: 1999-08-03
Abstract: The present invention discloses a method of and apparatus for regulating the power of signals transmitted by transmitting units, such as mobiles or base stations, that are using the same channel in a cellular radio system.  An iterative process is disclosed in which the demands of synchrony and coordination among the transmitting units are relaxed.  The power of the signals converges at a geometric rate to optimal transmission powers, where the optimal transmission powers are defined as the minimum powers required to maintain the ratio of carrier power to co-channel interference power at least as large as some pre-fixed target value obtained from quality of service considerations.  As a result of relaxing the demands of synchrony and coordination, expensive clock or timing mechanisms are not required, thereby reducing the costs of power control.
