Patent CA-2352802-A1 (CA)
Title: Preparation of multiwall polymeric microcapsules from hydrophilic polymers
Inventor: PEKAREK KATHLEEN
IPC: A61K47/34
Filed: 1998-12-01
Abstract: Two or more hydrophilic, water soluble polymers that are not soluble in each other at a particular concentration and temperature, but which have a positive spreading coefficient in solution, are used to form multi-layered polymeric microspheres. The multi-layer microspheres produced by the method are distinguished by extremely uniform dimensioned polymer layers and actual incorporation of a substance to be delivered into the polymer layers. In the preferred embodiment of the method, two polymers are dissolved in an aqueous solvent, the substance to be incorporated is dispersed or dissolved in the polymer solution, the mixture is suspended in an organic solvent or polymer/water mixture and stirred, and the solvent is slowly evaporated, creating microspheres with an inner core formed by one polymer and an outer layer formed by the second polymer.
Patent CA-2352942-A1 (CA)
Inventor: CONDRA RICHARD CARROLL
IPC: H05K3/24
Filed: 1999-11-24
Abstract: This invention comprises a driven conveyor for transporting work pieces into one or more flood plating cells for electroplating a metal onto the planar surfaces and surfaces of the through holes of the work piece. An electrolyte solution is pumped by one or more recirculating pumps into the flood cell at such a rate as to maintain the liquid at a desired level covering the anodes and work pieces while work pieces are moved through the cells. One or more power sources provide direct current to the anodes and to the electrified contactors to transmit electrical current to the work pieces. The electrified contactors are positioned across the path of the work piece and spaced outside of the flood cell such that the electrolyte solution does not contact the contactors. Plating will occur so long as the work piece is in contact with one or more of the electrified contactors and the electrolyte.

Title: Draw bar swivel hitch
Inventor: SCHROEDER JAMES W
IPC: A01B59/042
Filed: 2002-01-16
Abstract: A pull-type implement has operating components that are driven by a mechanical drive line on the tongue of the implement. An upper gear box is fixed to the front end of the tongue and a lower gear box swivels relative to the upper gear box about an upright axis passing through the two gear boxes. A hitch that establishes a draft connection between the tongue and the draw bar of a towing tractor has a fore-and-aft receiver that extends beneath the lower gear box and has a lower pivotal connection with the tongue at that location. A mast fixed to and projecting upwardly from the receiver has an upper pivotal connection with the tongue at a location above the upper gear box. The receiver has a forwardly facing socket that loosely receives the draw bar to permit the draw bar to swing up and down to a limited extent about a transverse axis and rotate side-to-side to a limited extent about a fore-and-aft axis when the draw bar is retained within the socket by a locking pin.

Title: Utilization of cos hydrolysis in high pressure gasification
Inventor: JOHNSON KAY A
IPC: C10K1/16
Filed: 2002-02-20
Abstract: The high pressure syngas product of a gasifier is routed first to a high pressure absorber unit that removes most of the H2S and some of the CO2 from the syngas. The syngas is then released through an expander to reduce the pressure of the syngas and simultaneously generate electricity. Steam is then injected into the syngas as a reactant in the subsequent COS hydrolysis step, converting the COS to H2S. After hydrolysis, the syngas is routed to a reabsorber where the remainder of the H2S and CO2 are removed. Sweet syngas can then be sent to a combustion turbine for use as a fuel source.
