Patent CA-2035010-A1 (CA)
Inventor: BACKMAN KEITH C
IPC: C12Q1/68
Filed: 1991-01-25
Abstract: The present invention involves methods of improving LCR and PCR amplification schemes by modifying at least one probe/primer end so that the probability of the probe/primer contributing to spurious signal development is greatly reduced. Only after specific hybridization of the modified probe/primer with true target, are the modified ends "corrected" in a target dependent fashion to allow participation of the probe/primer in the enzymatic assembly reaction. Specific modifications depend on whether the assembly is done by ligation (as in LCR) or by extension/elongation (as in PCR).

Patent CA-2040733-A1 (CA)
Inventor: BOJANIC DEJAN
IPC: B01L3/00
Filed: 1991-04-18
Abstract: An assay tray assembly and an assay tray primarily for chromatographic analysis has a plastics moulded test tray 1 mounted on a plastics moulded collection tray 72.   The test tray has a spaced array of chambers 3 disposed as per a microtiter plate.   Each chamber has a bottom outlet port 5 formed by a flange 8 which retains within the chamber a chromatographic medium to which test liquid deposited in the chamber is to be subjected for the percolate or eluate liquid to emerge from the respective outlet ports.   The collection tray 72 has a spaced array of wells 16 disposed as per a microtiter plate to correspond with the chambers 3 and the tray 1 is mounted on the tray 72 for each chamber to communicate with a corresponding well 16.   Each chamber 3 has a tubular spigot part 12 which extends into the respective well 16 to alleviate cross contamination of the liquid derived from the outlet ports 5.   The depth of entry of the tubular spigots 12 into their respective wells 16 is restricted by abutment between the bottom of the test tray with the top of the collection tray.   The volume of each well 16 beneath the tubular spigot it receives is adequate to accommodate all of the eluate or percolate derived from the chamber 3 with which it communicates to alleviate liquid on the spigot parts from dripping into wells with which those tubular spigots are not associated (and thereby cause cross contamination) when the trays are separated for analysis of the percolate or eluate.

Title: Oscillating spray apparatus
Inventor: DUNSTAN GORDON R
IPC: C23C4/123
Filed: 1991-04-23
Abstract: ABSTRACT            A device for gas atomizing a liquid stream, such as a stream of molten metal or metal alloy, has an atomizing device including, for example, an annular opening for receiving the stream.  The atomizing device is arranged for applying atomizing gas to the stream so as to form a spray of atomized particles.  The atomizing device includes at least one atomizing rotor which produces an atomizing gas flow field which is asymmetric with respect to the axis of the stream whereby, by varying the positional relationship of the asymmetric gas flow field with respect to the stream, movement is imparted to the spray.  The atomizer itself may also be tilted to and fro, the movements in combination enabling more flexibility with improved uniformity and control of deposition.

Title: Control of flow and production of water and oil or bitumen from porous underground formations
Inventor: MCKAY ALEXANDER S
IPC: E21B43/24
Filed: 1992-02-28
Abstract: An oil or bitumen-producing well which has undergone water coning with resultant production of substantially only water or a very reduced amount of oil is treated to restore oil production and to prevent water coning by introducing into the location of the oil or bitumen-producing formation which has undergone water coning or into the water-producing formation which gives rise to water coning, an oil-in-water emulsion under conditions such that the oil or bitumen in the oil-in-water emulsion is caused to become entrapped in the formation to create or generate a high oil or bitumen saturation plug to form a substantially water impermeable barrier at a substantial radial distance from the point of introduction or from the well from which the oil or bitumen is produced from said formation. In the broadest aspect of this invention, production or recovery of oil or bitumen produced or recovered in the form of an oil-in-water emulsion from a porous water containing and oil or bitumen producing formation is maintained and improved by maintain-ing the temperature of the produced oil or bitumen at a temperature not lower and preferably greater than Tc wherein Tc is the minimum temperature for the oil or bitumen, such as in the form of an oil-in-water emulsion, to flow through the porous water containing and oil or bitumen producing formation.

Title: Insulation wrapping strip with variable configuration
Inventor: PETTY PHILLIP C
IPC: B29C43/22
Filed: 1992-03-09
Abstract: ABSTRACT          The insulating coating for an object such as a rocket motor casing is formed by wrapping a strip of insulating material upon the surface of a rotating mandrel.  By means of this invention, it is possible to wrap a strip of malleable material such as rubber from an extruder onto a complex shape while exercising precise thickness control, thereby eliminating the need for machining the outer surface.  The strip is run through a forming mill of unique construction which shapes the strip during the wrapping process to conform most precisely with the topagraphy of the mandrel.  The mill automatically varies 40th the taper and the width of the strip. The final wrapped product has a smooth outer surface that requires minimal finishing.

Abstract: REMOVAL OF VANADIUM FROM PHOSPHORIC ACID                 ABSTRACT OF THE DISCLOSURE        An   apparatus   for  removing  vanadium  from phosphoric   acid   includes   a   precipitator  that receives  vanadium-containing process-feed phosphoric acid   and   adds  an  oxidant  to  the  process-feed phosphoric  acid,  whereupon  precipitates containing phosphorus  and  vanadium  are formed in a phosphoric acid  filter  feed  slurry.  The solid precipitate is removed  by  a  filter.  The filtrate, after optional further  oxidation,  is  contacted to an ion exchange resin   to   remove   additional  vanadium  from  the filtrate  to  produce  a  phosphoric  acid product of reduced  vanadium  content.  A first portion of the phosphoric   acid   product   is   removed  from  the apparatus  for  further  use.    A  reducing agent is added  to  a  second  portion  of the phosphoric acid product,  and  the  reduced  acid  is  used  to strip vanadium  from  the  loaded  ion exchange resin.  The vanadium-loaded  second  portion  of  the  phosphoric acid  is  mixed with fresh phosphoric acid and fed to the   precipitator.    The  phosphoric  acid  in  the precipitator  has  a  phosphate content of from about 40-45   percent,  and  at  least  a  portion  of the phosphoric  acid  in  the precipitator is produced by diluting  more  concentrated  phosphoric  acid to the 40-45 percent phosphate range.
