Patent CA-2269385-A1 (CA)
Title: Simultaneous detection isotopic ratio mass spectrometer
Inventor: MERREN THOMAS OLIVER
IPC: H01J49/30
Filed: 1999-04-19
Abstract: The invention comprises a mass spectrometer 1 and a method of mass spectrometry that is especially useful for the measurement of the isotopic composition of hydrogen in the presence of a helium carrier gas. Interference to the accurate measurement of the small HD+ peak at mass-to-charge ratio 3 by the much larger He+ peak at mass-to- charge ratio 4 is reduced by provision of an energy filter 35 in the ion detector assembly used to collect HD+ ions. This prevents ions of He+ which have lost energy through scattering, etc giving rise to a signal from the HD+ detector and distorting the deuterium hydrogen isotopic ratio measurement. Such a mass spectrometer 1 is typically used in conjunction with a continuous flow inlet system 4 based on an elemental analyzer that converts hydrogen present in a sample to gaseous hydrogen in a flow of helium carrier gas. Another embodiment of the invention provides a similar mass spectrometer useful for carbon or oxygen isotopic determinations in carbon dioxide gas.

Inventor: SCHMIDT ERNEST W
IPC: B27G1/00
Filed: 2000-07-10
Abstract: The present invention is directed to a process whereby low-grade lumber, (i.e., lumber having surface defects such as knots, voids, wane, and bark pockets, and warp defects such as twist, bow, crook and sweep), is converted to higher grade lumber and panel products. The process of the present invention involves first categorizing low-grade lumber, arranging a specified number of the categorized low-grade lumber side by side in a manner which offsets the surface defects on adjacent lumber by a minimum distance, and then face-laminating the categorized low-grade lumber together to form a cant. Warp defects such as bow, twist and crook are also offset in the arrangement of the cant and are straightened through the clamping and bonding process. The cant is then re-sawn to produce new, laminated wood products of a higher grade, each new laminated wood product including portions of the original lumber. The wood products may be structural dimensional lumber, 2x4 to 2x12 studs, and panels varying in thickness and width.
