Patent CA-2118572-A1 (CA)
Inventor: PAN CHUEN Y
IPC: B01D53/04
Filed: 1994-03-07
Abstract: The process is conducted in a circuit having first and second adsorbers and a product reservoir vessel, connected serially. The feedstock is a gas mixture containing contaminant and product components (for example, air containing N2 and O2). The process steps involved are: (1) feeding a charge of feed gas into the first adsorber, temporarily retaining it therein, and pressurizing it, so that the adsorbent adsorbs most of the contaminant component and purified product gas is produced; (2) co-currently depressurizing the first adsorber by discharging purified product gas through the second adsorber and reservoir vessel; (3) counter-currently venting both adsorbers; (4) partly repressurizing both the adsorbers with purified gas from the reservoir vessel; and then repeating steps (1) - (4) inclusive. The process includes the following advantages over PSA systems using parallel arranged adsorbers: reversal of product concentration gradient in the adsorbers is avoided; and co-current de-pressurization of the first adsorber to a very low level prior to counter-current venting is made possible, improving process efficiency.

Patent CA-2121831-A1 (CA)
Inventor: HOMAN EDWIN D
IPC: B01D21/02
Filed: 1994-04-21
Abstract: The separator comprises an elongated, cylindrical, horizontal pressure vessel. An involute feed inlet introduces the drilling fluid into the top of the vessel chamber at its first end. The feed inlet is designed to reduce the flow velocity of the incoming feed stream and introduce it horizontally toward the first end head of the vessel. A weir, slanted away from the first end head, extends upwardly from a point close to the head's base. The curved head, vessel side wall and slanted weir form an inlet compartment of hopper-like configuration,designed to funnel settling cuttings to a bottom outlet for removal with an auger pump. This design enables the cuttings to be removed while drilling progresses, without the build up of cuttings piles. The vessel also has a second weir at about its midpoint, for trapping fine solids in a second compartment. Riser outlets are provided in the second compartment for water removal and in the third compartment for oil removal. Gas is removed through an overhead outlet. A process is practised whereby pressurized drilling fluid returning from a well undergoing drilling is introduced into a closed pressurized separator wherein the liquid, gas and coarse cuttings are separated, the cuttings are collected and removed from the separator as a separate stream while drilling fluid continues to enter the separator, and the liquid and gas are also separately removed from the separator.

Title: Extraction of mercury and gold from mine tailings
Inventor: KNELSON BENJAMIN
IPC: B04B3/00
Filed: 1994-05-17
Abstract: A centrifugal separator includes a centrifuge bowl having a plurality of annular rings on the peripheral surface. An outer bowl provides a jacket from which water is injected through holes in the inner bowl into recesses between the annular rings. Feed materials containing gold and mercury are separated so that the gold and mercury is collected with the heavies in the recesses. The liquid mercury escapes through the holes in the inner bowl onto the inner surface of the outer bowl which is provided with an annular receptacle and is shaped to collect the mercury at the receptacle axially spaced from the open mouth of the bowl. A plurality of outlets in the annular receptacle allow the escape of the mercury into a secondary launder inside the outer launder for the main discharge materials from the open mouth. The liquid mercury is thus collected separately from the solid heavies within the bowl and separately from the discharged light material.

Title: Second-harmonic generation in semiconductor heterostructures
Inventor: JANZ SIEGFRIED
IPC: H01S5/32
Filed: 1994-06-28
Abstract: Second-Harmonic Generation in Semiconductor Heterostructures Abstract of the Disclosure Quasi-phase matched (QPM) second-harmonic (SH) generation in the reflection geometry is described. The SH intensity can be strongly enhanced by spatially modulating the optical properties of the nonlinear medium. This type of quasi-phase matching is demonstrated using an Al0.8Ga0.2As/GaAs heterostructure designed for .lambda.=1.06 µm incident light. The SH light intensity generated in reflection from the heterostructure is enhanced 70 times relative to the SH response of a homogeneous GaAs wafer. A Fabry-Perot resonant cavity design employs this structure to make thin films with extremely high SH generation efficiencies. This is of particular interest used in vertical cavity surface emitting lasers (VCSELs).

Title: Automated longitudinal position translator for ultrasonic imaging probes, and method of using same
Inventor: WEBLER WILLIAM E
IPC: A61B8/12
Filed: 1993-06-29
Abstract: A longitudinal position translator includes a probe drive module (20) and a linear translation module (48). The drive mo-dule (20) is coupled to an ultrasonic imaging probe assembly (12) having a distally located transducer subassembly (16) such that longitudinal shifting of the subassembly (16} may be effected. The module (20) is mounted to the translation unit (48) sa as to be moveable between a condition whereby longitudinal shifting of the subassembly (16) can be conducted either manually or auto-matically. When in the latter condition, the probe drive module (20) will engage a motor-driven screw associated with the linear translation module (48), causing the probe drive module (20) to be displaced at a constant rate. The distally located ultrasound transducer ( 16) is thus longitudinally shifted during an ultrasound scan to allow axially-spaced 360° data "slices" of surrounding tissue to be obtained, with reconstruction into a two or three-dimensional representation of the scanned tissue.

The ratio (V/W) of a compressing speed V relative to the moving speed W of the position of the heated area (5) in reference to the thickened portion (1a) of the metallic member (1) is progressively increased from a small value, em-ployed at an initial stage of wall thickening, along the metallic member (1) to an aimed value, employed at a steady stage of wall thickening, to thereby progressively increase a wall thickening ratio along the metallic member (1) to a designed value. The subsequent wall thickening is carried out while the ratio is maintained at said designed value for the steady stage of wall thickening. A method of connecting two metallic members (1) in end-to-end fashion and a method of connecting a beam to the metallic member (1) are also disclosed.

Abstract: A transmission power control method in CDMA, which is capable of increasing the capacity in terms of the number of subscribes by reducing transmission power by achieving highly accurate transmission power control during a soft handoff.  A mobile station determines its transmission power during the soft handoff by comparing a transmission power control bit from the old base station with that from a new base station, and by selecting the transmission power control bit that indicates lower transmission power of the mobile station.  In addition, the mobile station determines the transmission power control bit for the base stations by comparing the received SIR from the old base station with that from the new base station, and by selecting the greater received SIR.  This make it possible to reduce the transmission power, and increase the capacity in terms of the number of subscribers.
