Patent CA-2450987-A1 (CA)
Title: Fuel cell separator and production method therefor
Inventor: NAKATA HIROMICHI
IPC: H01M8/00
Filed: 2003-11-26
Abstract: A low-cost fuel cell separator having a metallic substrate which is able to stably maintain low electric resistance (high electrical conductivity) and high corrosion resistance for a long period is provided. The separator has a metallic substrate having an oxide film forming a surface thereof and made from an oxidization of a metal of the substrate, and an electrically conductive thin. film formed on a surface of the oxide film of the substrate. Due to this construction, low electric resistance (high electrical conductivity) is achieved by the electrically conductive thin film. Furthermore, even if the electrically conductive thin film has pinholes, the oxide film substantially prevents or reduces elution from the separator substrate, thereby achieving high corrosion resistance. Stall further, since the oxide film is formed by oxidation of the substrate, the oxide film can be formed at a lower cast than an oxide film formed from a different metal.

IPC: A63H33/22
Filed: 2002-07-01
Abstract: A swinging bob toy (100) having a middle bob (311) with a non-cylindrically symmetric internal structure. The center of mass is located near the middle of the bore axis (335), and the percentage azimuthal variation V in the moment of inertia I) about an axis in the equatorial plane (337), given by V=100x[I(.PHI.max)-I(.PHI.min)]/I(.PHI.max), is minimized, for instance by positioning the internal components to produce a weight distribution with n-fold symmetry, where n>=3. In one preferred embodiment, the bobs (310, 311) are equipped with ligths (377) powered by on-board batteries (375). Flat cylindrical batteries are mounted on an equatorial circuit board (379) with their axes of symmetry perpendicular to the bore axis. To allow battery replacement, the top and bottom halves (311a, 311b) of each bob are removably attached by screw-secured posts (371a, 371b) parallel to, but offset from, the bore axis. An on/off switch (380) is accessible via a small aperture through a transparent outer shell (351). In one preferred embodiment, the lights flash a frequency which is not visible when the bobs are stationary, but visible when the bobs are in motion.

Title: Process and apparatus for flaxseed component separation
Inventor: CUI WUWEI
IPC: A23L25/00
Filed: 2002-12-12
Abstract: A continuous process for separating components of flaxseed is described.  Flaxseed is dried to a moisture content of from about 0.5% to about 3.0%, after which is introduced into a separation chamber having an abrasive rotator therein. As the flaxseed passes over the abrasive rotator, contact with rotator separates the flaxseed components into hulls and kernels. Hulls and kernels are separated and may be used in this form or processed further. Hulls may be further processed by extraction with water and with hexane to remove flaxseed gum and oil, respectively. These two extractions may be done in any order. The process results in a lignan-rich component of flaxseed, a gum extract and oil. These separate components of flaxseed may be used in products such as feed, personal care products or nutraceuticals.
