Patent CA-2490420-C (CA)
Inventor: HEON RENE
IPC: G01N21/63
Filed: 2003-06-17
Granted: 2012-01-10
Abstract: An apparatus and a method are disclosed for use with Laser Induced Breakdown Spectroscopy (LIBS) systems that can be applied to the real time analysis of molten materials or liquid. Since it is difficult to prepare a surface representative of the bulk when dealing with high temperature molten material, the invention, in one aspect, uses a forced gas flow through a tube insertable inside the molten material to generate a bubble. The inner surface of the bubble is a representative of the composition of the material. LIBS performed on such a surface produces an accurate real time analysis of material, even when other processing of material, e.g., copper smelting, etc., is being conducted.

Patent CA-2511965-C (CA)
Inventor: HUANG ZHONG-DI
IPC: B27N7/00

Granted: 2009-01-20
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.
