Title: Method of manufacturing a plastic encapsulated structural member
Inventor: JOHNSON MICHAEL D
IPC: B29C33/14
Filed: 2003-12-19
Abstract: A method of manufacturing a plastic encapsulated plastic structural member includes the steps of forming a mold having first and second mold parts which form an enclosed mold defining a cavity therein having a configuration the same as the configuration of this structural member to be formed. A core of wooden material having holes on each of two opposed surfaces is formed and positioned in the cavity so that pins on the mold parts engage the holes. A foamable plastic material and nitrogen is injected under low pressure into the cavity to cause the plastic material to foam up and fill the space between the core and the cavity all around the core.      The plastic material is then allowed to harden to form a plastic layer around the core. The mold parts are then removed. The holes may be closed with the plug of additional plastic material.
Patent CA-2454826-A1 (CA)
Inventor: RUSSELL ALAN J
IPC: C12N11/08
Filed: 2002-07-24
Abstract: This invention provides a method of irreversibly immobilizing an enzyme into polyurethane coatings. This invention also provides for an enzyme-containing coating having a degree of immobilization of the enzyme of approximately 100%.  The synthesis of waterborne polyurethane coatings in the presence of enzyme has enabled the irreversible attachment of the enzyme to the polymeric matrix.  The distribution of immobilized enzyme as well as activity retention are homogeneous within the coating. Decreasing ECC hydrophobicity, via the use of a less hydrophobic polyisocyanate prepolymer during polymerization, significantly enhanced the intrinsic activity of the ECC.

Filed: 2002-09-10
Abstract: A liquid filtering apparatus for mounting in a housing defining an inlet and a drain. The liquid filtering apparatus is positioned in use to filter liquid flowing from the inlet (23) to the drain. The apparatus comprises a permeabl e screen (19) rotatable about a substantially horizontal axis and forming a barrier between the inlet and the drain. A rotatable wheel is disposed withi n the screen and coupled to the screen so that rotation of the wheel causes rotation of the screen. The wheel is defined by vanes (5-12) extending towar ds the screen so as to divide a space around which the screen is arranged into sections which are substantially isolated from each other except via the drain. A stationary baffle (13) is arranged adjacent a portion of the screen to prevent liquid from flowing into the wheel through that portion of the screen. The baffle is positioned such that water flows more readily into sections of the wheel on one side of a vertical plane through the rotation axis than the other sections. Thus the wheel is unbalanced by water retained in sections of the wheel so as to cause the wheel to rotate.
