Patent CA-2526568-A1 (CA)
Title: Device and method for cleaning a tube
Inventor: BROVOLD CHRISTOPHER T
IPC: B08B9/00
Filed: 2004-06-10
Abstract: A method and device for cleaning the inside of a liquid dispensing tube that is contaminated with a previously dispensed liquid. The contaminated liquid dispensing tube is filled with a cleaning fluid. The liquid dispensing tube is then impacted with an impacting device. The impacting of the liquid dispensing tube creates pressure waves in the cleaning fluid. The pressure waves dislodge the liquid contaminate from the inside of the liquid dispensing tube while a flowing cleaning fluid flushes the liquid contaminate out of the liquid dispensing tube.

Patent CA-2527728-A1 (CA)
Inventor: COX JAMES W
IPC: C12N5/00
Filed: 2004-05-28
Abstract: The present invention features methods for specifically micropositioning cells on a substratum. Cell-adhesive substances that bind to naturally-occurring or artificially-attached cell-surface moieties are deposited onto the substratum (e.g., using an inkjet printer), after which cells are incubated with the substratum such that they attach to the substratum via the cell-adhesive substances. The methods of the invention can be used to generate complex two-and three-dimensional patterns containing multiple cell types, e.g., for tissue engineering.

Patent CA-2536496-A1 (CA)
Title: Positive pressure gas jacket for a natural gas pipeline
Inventor: WILDE GLENN
IPC: F17D5/02
Filed: 2004-08-27
Abstract: The present invention provides a method and apparatus whereby the intake pipeline running between the production chamber of a natural gas well and the suction inlet of an associated wellhead compressor is completely enclosed, in airtight fashion, within a jacket of natural gas under positive pressure (i.e., higher than atmospheric). Being enclosed inside this "positive pressure jacket", the intake pipeline is not exposed to the atmosphere at any point.  This allows gas to be drawn into the compressor through the intake pipeline under a negative pressure, without risk of air entering the intake pipeline should a leak occur in the pipeline. If such a leak occurs, there will merely be a harmless transfer of gas from the positive pressure jacket into the intake pipeline. If a leak occurs in the positive pressure jacket, gas therefrom will escape into the atmosphere, and entry of air into the positive pressure jacket will be impossible.
