Patent CA-2475481-C (CA)
Title: Dynamic magnet system for generating electric power
Inventor: XIN HAO
IPC: H02K35/02
Filed: 2003-02-18
Granted: 2009-06-30
Abstract: A dynamic magnet system, particularly useful for electrical generation, employs multiple magnets (2, 4) in polar opposition to each for individual movement relative to a support structure (6). The magnets (2, 4) have a critical angle of displacement from a horizontal static position of less than 1 degree, with at least some of the magnets (2, 4) having mutually different properties. With different magnetic strengths, a greater movement is produced for both magnets in response to movements of the support structure, for particular ranges of magnetic strength ratios, than would be the case with equal magnets. The magnet movement can be translated into an electrical signal to power an operating system. Ultra low friction ferrofluid bearings can be used to establish static coefficients of friction between the magnets and support structure less than 0.02, enabling useful power generation from only slight movements of the support structure.

Patent CA-2517533-C (CA)
Title: Non-rotatable wear ring and retainer sleeve for a rotatable tool
Inventor: SOLLAMI PHILLIP A
IPC: E02F5/14
Filed: 2005-08-30
Granted: 2009-02-24
Abstract: A compressible sleeve for fitting around the shank of a rotatable tool has a cut out portion at the forward end thereof. The sleeve is compressed to a diameter less than the inner diameter of the bore of a tool holder by an annular wear ring having a generally cylindrical central opening with a diameter larger than the diameter of the bore of the tool holder, but having an inwardly directed projection that retains the cylindrical sleeve in a diameter that is less than the diameter of the bore of the tool holder. When the shank of the tool is subsequently driven into the bore of the tool holder, the wear ring is forced forwardly along the sleeve until the projection of the wear ring falls between the cut out portions of the sleeve thereby allowing the sleeve to expand to the diameter of the bore of the tool holder. The outer walls of the cut out portion of the sleeve engage the ends of the inwardly directed projection of the wear ring thereby preventing the wear ring from rotating with the tool.

Abstract: A load determining section (54, S10) of a drive control apparatus (52, 53) for forklift (10) determines a load state related to a loading attachment (22). In a case where a connection determining section (54, S20) determines switching to a connection state, if the load state determined by the load determining section (54, S10) requires that driving of a vehicle body (11) be limited, a disconnection control section (54, S25) forcibly disconnects a transmission of a driving force to a drive wheel (14). Thus, the forklift (10) is prevented from being started in a state that is likely to make the driving of the forklift unstable (Fig. 8).

Abstract: The invention relates to a compressed air foam producer, wherein a fire or decontamination specific additive is injected directly into the foam forming flow supplied to the main water flow and/or the main water flow. A mixing pump for the foaming agent draws off an auxiliary and motive water flow, wherein initially the additive and then the foaming agent is injected. The foaming agent-additive-water mixture, which is produced directly on site, is mixed well together and with the main water flow ensuring a fine, uniform distribution of the additives in the compressed air foam. The thus produced compressed air foam ensures optimal, economical and environmentally friendly fire-fighting and decontamination.
