Patent CA-2502228-A1 (CA)
Title: Self-destructing filter cake
Inventor: DISMUKE KEITH
IPC: C09K8/72
Filed: 2003-10-17
Abstract: A composition and method are given for self-destructive fluid loss additives and filter cakes in wellbores and subterranean formations. The fluid loss additives and filter cakes are formed from a mixture of particulate solid ac id- precursors, such as a polylactic acid or a polyglycolic acid, and particulat e solid acid-reactive materials, such as magnesium oxide or calcium carbonate. In the presence of water, the solid acid-precursors hydrolyze and dissolve, generating acids that then dissolve the solid acid-reactive materials. The composition is used in oilfield treatments such as drilling, completion and stimulation where it disappears when it is no longer needed without the use of mechanical means or injection of additional fluids.

Title: Method and apparatus for cleaning a furnace burner
Inventor: PATRICK DOUG
IPC: F23J1/06
Filed: 2005-11-04
Abstract: The present invention provides a furnace burner scraper that cleans a buildup of debris on the wall of a furnace in the vicinity of the furnace burner, and preferably the exterior wall of the furnace burner, without manual intervention and without shutting off the furnace burner. The furnace burner scraper intermittently lunges forward to scrape debris from the furnace wall about the discharge outlet of the firing tube and the exterior surface of the firing tube, then retracts from the furnace interior so that the scraper head does not melt. The invention thus allows the furnace burner to operate for long periods of time without interrupting the furnace's production.

Abstract: Methods of consolidating independent owners of distribution warehouses into a Real Estate Investment Trust (REIT) for purposes of achieving economics of scale, for obtaining favorable mortgage financing and for creating a vehicle to enable periodic refinancing and investment of proceeds from such refinancing in real estate opportunities. The REIT is formed and independent owners of distribution warehouses are assembled and selected to participate in the REIT. The participant enters in a sale-leaseback agreement with the REIT  and transfers title in their warehouses to the REIT. The REIT finances the purchase of the warehouses by securing a non-recourse loan with at least a seven-year term, serviced on at least a seven-year debt payment schedule. On a periodic basis, preferably every seven years, each warehouse is reappraised, new leases entered into between the REIT and each participant, and new mortgage loans issued for each warehouse. The REIT invests proceeds from the new mortgage loans in real estate opportunities to produce investment revenue.  The REIT distributes 90% of net earnings from the investment revenue to the participants.
