Patent CA-2495481-A1 (CA)
Inventor: CUOMO ANGELO V
IPC: B65D71/62
Filed: 2003-08-06
Abstract: The food carrier (20) has a central vertical support panel (22) with a handle (34) and a pair of trays (30, 32) with beverage cup holders (48, 50) attached to the central support panel (22). A folded sidewall structure can be unfolded to start the formation of the trays, and a folded bottom panel or two-panel structure unfolds into the side-wall outline to stabilize the sidewall and hold the carrier (20) erect while it is resting on a flat surface thus to make unfolding and loading the carrier (20) quicker and easier. An auxiliary tray (70) can be slipped into the central vertical support (22) to hold solid foods, and both beverages and solid foods can be carried. Advantageously, the auxiliary tray can have substantially the same structure as the first carrier unit, except it has no beverage-receiving holes. It can be mounted to ride "piggyback" on the first carrier, or it can be used alone.

Patent CA-2506908-A1 (CA)
Inventor: CARLSON DENNIS D
IPC: C23F1/00
Filed: 2005-05-06
Abstract: Improvements in composite shingle manufacturing are realized through the use of an acid etching solution along with machining to generate a molding surface particularly well suited for the molding of shingles having the look of "natural" materials, such as slate. Upon the selection of a specific pattern that will define the primary shape for molded composite shingles, machine tools are used to cut the pattern into the base mold to form a molding surface. Finer details are then added to the molding surface through the use of an acid etch solution. The base mold with the sculpted molding surface may then be used in traditional molding techniques to produce composite shingles having an exposed surface that closely replicates the appearance of naturally occurring materials.

Patent CA-2511965-A1 (CA)
Inventor: HUANG ZHONG-DI
IPC: B27M3/00
Filed: 2005-07-13
Abstract: The present invention discloses a method for manufacturing a fir wood decoration material by adding a "sealing-coating" technique to a white paste mending process for manufacturing traditional wood decoration materials. Due to the color staining and oil staining properties, the knots of wood material is mended by a white paste after a fir decoration material is formed. General wood flour is used for the mending, and then sealing paint is coated onto the white paste to preclude the occurrence of color staining and oil staining. After the defects of color stain, oil stain, and obvious lines of the fir wood are eliminated, it is not necessary to remove the knots of the fir wood during its manufacturing, and the coating will not be peeled off easily, so as to improve the yield rate and lower the cost.
