Title: Tire inflation method and apparatus
Inventor: SOWRY CLIVE ROBERT
IPC: B60S5/04
Filed: 1997-02-07
Abstract: The method and apparatus allow deflating a tire and thereafter re-inflating it using,a single source of pressurized inert gas.      The pressurized inert gas is used to increase the rate at which gas is vented to the atmosphere from the tire during deflation.      Once the pressure inside the tire reaches the sub-atmospheric level, an outlet valve is closed and the inert gas is forced into the tire until it is re-inflated. This method and apparatus allow simplifying the process, compared to previously known apparatus and methods.
Patent CA-2201541-A1 (CA)
Inventor: JERVIS TIMOTHY TRISTRAM
IPC: E21B47/12
Filed: 1997-04-02
Abstract: Methods and apparatus are described for recognizing wellbore telemetry signals, wherein a received analog telemetry signal is compared to a number of possible analog signals. The probability of representing the received signal is determined for each of the possible analog signals. By selecting the signal with the highest probability, the received signal is demodulated. For calculating the probability, Bayes' method or any equivalent thereof is used. In variants, this probabilistic method is used to determine the synchronization point of the telemetry signal and for controlling the noise removal therefrom. The method and apparatus show increased accuracy in recognizing and demodulating the received signals.

Title: Stent delivery and deployment method
Inventor: LASHINSKI ROBERT
IPC: A61F2/06
Filed: 1995-10-19
Abstract: An encapsulated stent device for implantation within the vascular system includes a balloon (36) of a balloon catheter (30) formed around and adhered to a wire-like stent (10) so that the outer surface of the device is more regular for delivery through the vascular system without an exterior sheath. The encapsulation securely anchors the stent (10) to the balloon (36) and maintains a low profile for negotiation of tortuous and narrowed vessels. Encapsulation requires placement of the stent (10) over the balloon (36), placement of a sheath (42) over the stent (10) on the balloon (36), heating and preferably pressurization of the balloon (36) to cause it to expand around the stent (10) within the sheath (42), and cooling while preferably maintaining pressure to cause the balloon (36) to adhere to the stent (10) and to set the shape of the expanded balloon (10). Retainers may be placed at the distal and/or proximal ends of the stent during the encapsulation process, or the balloon material may expand to form retainers (54). The balloon (36) defines at least three folded wings for symmetrical expansion of the stent (10), and one or more connected or non-connected stents may be encapsulated depending upon the area to be treated.

Patent CA-2209007-A1 (CA)
Inventor: VANDEN HEUVEL DEAN PAUL
IPC: H04B7/185
Filed: 1995-11-17
Abstract: A subscriber unit (26) communicates with a satellite (12) using electromagnetic signals so that observations (102) of the signals are obtained. Surface contours are generated (104) based on the signal component measured. The surface contour intersections produce candidate locations on the earth's surface. The candidate locations seed a least-squares estimation to produce final locations. Data produced during the least-squares fit is used to generate confidence ellipses (116) about the final locations. Most likely actual locations are determined from the fit associated with the confidence regions. A variety of signal source measurements can be used while providing a best estimate of a signal source location when an exact solution is not mathematically possible. The location is converted to coordinates that can be used in a satellite communication system (10) for making decisions regarding the granting or denying of communication services, billing rate and the like.

Title: Method of detecting gene expression and/or of preventing such expression in cells
IPC: C12Q1/68
Filed: 1997-09-12
Abstract: A method of amplifying a nucleotide sequence complementary to an mRNA template derived from genomic DNA. The method involves the following steps.  A sample mixture containing an mRNA template and corresponding genomic DNA is provided, the genomic DNA including at least two exons separated by at least one intron.  A pair of intron-blockers are introduced into the mixture, the intron-blockers comprising a sequence of intron-specific oligonucleotides modified to prevent nucleotide extension in conditions promoting polymerase chain reaction.  A primer pair promoting amplification of cDNA derived from the mRNA template is introduced into the mixture and then reverse transcription polymerase chain reaction is carried out to amplify cDNA.  Detection of the cDNA is proof of the existence of mRNA in the sample, and thus proof of expression of the corresponding gene.  The method avoids false positives caused by amplification of genomic DNA as well as cDNA based on an mRNA template.  The invention includes a method of suppressing gene expression in vivo, which comprises exposing cells containing a gene to be suppressed, made up of exons and at least one intron, to intron-blockers having nucleotide sequences that bind to the intron to prevent gene expression.

Title: Cooling of sheet material
Inventor: MOEDER CLAUDIO
IPC: B29C48/90
Filed: 1996-06-18
Abstract: A calibration plate for the cooling of thermoplastic sheet material comprises a plurality of passageways for chilled fluid characterised in that at least part of the or each passageway is open to the operative surface of the plate. As with traditional calibration plates, vacuum passages may also be provided to draw a vacuum and maintain the sheet to be cooled in close contact with the plate during the cooling operation. The calibration plate of the invention therefore allows chilled fluid, in particular chilled water, into direct contact with the sheet surface. This has two beneficial effects: firstly, it lubricates the sheet surface, cutting down the friction; and, secondly, with direct contact between the cooling medium and the sheet surface the cooling effect is much more rapid and marked. The calibration plate of the invention therefore enables much higher throughput speeds to be achieved, speeding up the entire process of the production of the sheet material.
