Patent number: 6173829Abstract: The board positioning device of the present invention is for optimally longitudinally positioning a board for trimming. The board is translated from an upstream position to a downstream position in a first direction towards the trimming saws. The board translates at a translation speed on a board translating device such as a lugged transfer chain. The board while translating in the first direction, is aligned longitudinally, that is, along its length, in a second direction perpendicular to the first direction so as to position the board relative to the saws. The board is urged by board ending means, such as ending rolls, in the second direction against a corresponding board positioning member, such as a shaft mounted paddle, on the board positioning device. In the preferred embodiment, the first and second directions lie in a generally horizontal plane.Type: GrantFiled: April 30, 1999Date of Patent: January 16, 2001Assignee: CAE Electronics Ltd.Inventors: James G.

Patent number: 5005773Abstract: A sonic generator comprises a resonant bar, a housing and magnetic excitation units connected between the resonant bar and the housing. The magnetic excitation units are connected to the bar at highly stressed points using a mounting connection which is a sleeve having an inside diameter slightly greater than the outside diameter of the bar. A resilient elastomer such as urethane is mounted between the sleeve and the resonant member. The sonic generator may be used for grinding purposes and, in particular, may be used to grind material exceptionally fine with reduced power consumption. The bar is substantially unrestrained so as to allow substantially free vibration.Type: GrantFiled: March 31, 1989Date of Patent: April 9, 1991Assignee: ARC Sonics Inc.Inventors: Christopher A. Nyberg, James G. Jackson, Jan Brdicko

Patent number: 4692060Abstract: A water-bag dam or dike comprises elongate tubes adapted to be filled with water. The tubes have three equal sides and are supported by longitudinal and lateral support members so that, when filled with water, they assume the shape of a substantially equilateral, triangular prism. The tubes can be stacked to make a dam or dike twice as tall and wide on the individual tubes. The tubes and support members can be transported to a flood situs and there be erected into an effective dam or dike just by filling the tubes with water.Type: GrantFiled: July 3, 1986Date of Patent: September 8, 1987Inventor: James G.
