Title: Method and apparatus for converting subscriber loops for delivery of both pots services and high speed data
Inventor: YEAP TET HIN
IPC: H04Q1/14
Filed: 2001-01-18
Abstract: In order to enable both POTS and high speed data communications via a plurality of subscriber loops connected to central office by way of a junction unit and a feeder cable, a bank of POTS splitters and a high speed data interface are located adjacent the junction unit and conductors of the subscriber loops are connected to the bank of POTS splitters. Preferably, the connector blocks in the JWI are duplicated in the box containing the POTS splitters. The usual jumper conductors in the JWI are removed and the connector blocks in the JWI connected to the connector blocks in the POTS  splitter box by bridging conductors. With this arrangement, it is possible to remake the connections to the subscriber loops one at a time, thus reducing disruption to service.

Title: Apparatus and method for open hole gravel packing
Inventor: HILL LEO E JR
IPC: E21B43/04
Filed: 1999-07-22
Abstract: The present invention provides apparatus and method for gravel packing open holes wherein hydrostatic pressure is maintained above the formation pressure ("overburdened condition") throughout the gravel pack process. The apparatus includes a completion string which contains a flow restriction device, a crossover device and a packer each above and below the crossover device. The string is set in the wellbore with the flow restriction device adjacent the producing formation.  The upper packer and the crossover device are set, which allows the gravel fluid to pass to the annulus, and return through the string. After gravel packing, the lower packer is set. The crossover device and the upper packer are retrieved from the wellbore leaving the flow restriction device and the lower packer in the wellbore. The system maintains the wellbore under overburdened condition throughout the gravel packing process.

Patent CA-2341745-A1 (CA)
Inventor: DANBY HAL
IPC: A61M5/148
Filed: 2000-06-15
Abstract: An infusion pump (10) includes a reservoir (18) containing a therapeutic liquid to be infused. The reservoir (18) includes an outlet (36) for the liquid. A volumetric air pump (24) is operatively associated with the reservoir (18) to pressurize the reservoir and thus drive liquid out the outlet (36). A valve (12) is operatively associated with the outlet (36) and  prevents the flow of liquid through the outlet until a select threshold pressure is obtained in the outlet. The valve thereafter maintains an openin g in the outlet that keeps the pressure in the reservoir (18) at substantially  the select threshold pressure, whereby the volumetric flow rate of liquid through the outlet (36) is proportional to the volumetric flow rate of air from the volumetric air pump (24). The valve (12) varies the opening in the outlet to maintain the select pressure. The outlet preferably consists of a flexible conduit (36) having a select undeformed inner cross-sectional area and the valve (12) variably restricts the flow of liquid through the outlet by pinching a segment of the conduit to vary the inner cross-sectional area of the segment of the conduit. A method of infusing therapeutic liquid to a patient includes providing a reservoir (18) containing a therapeutic liquid,  providing a volumetric air pump (24) to pressurize the reservoir to flow liquid out the liquid reservoir through an outlet (36) and maintaining a select pressure in the reservoir so that liquid through the liquid outlet is  proportional to the volumetric flow rate of the volumetric air pump.

IPC: B65C9/18
Filed: 1999-10-29
Abstract: Label applicator apparatus (10) for applying a self-adhesive label (12A) to a surface (16) which is movable relative to the apparatus.  The label is carried on an elongate backing web (14) having a plurality of labels (12) adhered to one side thereof in longitudinally spaced relationship. The apparatus includes an edge (22) over which the web is drawn whereby, when a force is applied along the web which exceeds a peeling threshold, the web is peeled away from the label and the label is dispensed at the edge. The apparatus includes pressing means (24) located a set distance from the edge for pressing the label against the surface as it is dispensed, thereby adhering the label to the surface, and means (28, 30) for applying a peeling force which is greater than the peeling threshold during dispensing of at least an initial portion of the label which spans the set distance to initiate dispensing of the label. The peeling force is operative during dispensing of the initial portion of the label and is inoperative during dispensing of a final portion of the label, wherein when the peeling force is inoperative, dispensing is continued due to an additional force being exerted along the web by a portion of the label which is adhered to the surface.

The oocytes are then cultured to form preimplantation embryos. Thereafter, at least one cell is removed from each of the pre-implan-tation embryos and the DNA digested with restriction endonuclease capable of cleaving the methylated transgene but incapable cleaving the unmethylated form of the transgene.

Patent CA-2363969-A1 (CA)
Inventor: CURLOOK WALTER
IPC: C22B15/00
Filed: 2001-11-26
Abstract: This invention provides a process for economical extraction of residual base metal values in furnace slags, by utilizing smelter by-product sulphuric acid for the pressure leaching of such slags after sufficient initial slow- solidification to induce crystallization. After final solidification and cooling the slags are ground and pulped, mixed with sulphuric acid in an autoclave, and reacted at temperatures up to 275°C and pressures up to about 940psi when applying an oxygen over-pressure of up to 75psi, for up to 2 hours. High degrees of extraction of contained nickel, copper, cobalt and zinc if present, are achieved which are subsequently recovered from the leachate. Whereas the furnace slags, as produced and untreated, present a potential long term environmental hazard, after extraction of their base metal values they are rendered virtually benign vis--à-vis the environment. This method of pressure leaching can be applied to crystallized converter slags enriched in cobalt during the smelting of metal and copper sulphide ores.
