Abstract: A vibratory screener including a screen with an upper surface, a lower surface, and a plurality of apertures, an attachment post extending above the upper surface of the screen, and a cleaning system positioned above the upper surface of the screen. The cleaning system includes a support plate, a plurality of arms extending radially from the support plate, and at least one brush extending downwardly from each of the arms. Each brush is positioned so that the distal end of at least one of its multiple bristles contacts the upper surface of the screen. The screener further includes a collection area positioned below the lower surface of the screen and a vibration generator that vibrates the screen and the cleaning system and causes the arms to rotate relative to the upper surface of the screen.

Abstract: A low profile, color-based counting system. A housing has a light source, such as a matrix of LEDs, preferably disposed in the housing for generating electromagnetic radiation upwardly. A removable, translucent tray is disposed above the light source. A second light source can be added above the tray, directing light downwardly thereto. A color camera is mounted on the housing and above the removable translucent tray.

Abstract: A log supporting and guiding apparatus for improved burning, the apparatus comprising: a base which rests on a fireplace floor or fireplace grate, the base comprising a front bar, back bar, a left connecting bar, a right connecting bar, and a plurality of strength reinforcing bars; a plurality of log retaining bars which are functionally attached to the base and angled off of the fireplace floor or fireplace grate; a left upright bar which is perpendicular, functionally attached to the left connecting bar at the bottom of the left upright bar, and closer to the front bar than the back bar; a right upright bar which is perpendicular, functionally attached to the right connecting bar at the bottom of the right upright bar, and closer to the front bar than the back bar; a cross bar which functionally connects the top of the left upright bar with the top of the right upright bar; a c-section bar for holding a log upright, which is functionally attached to the top of the right upright bar; and an inverted c-sectio

Abstract: This tripod is mounted on a camera by a flat mounting plate having a slot in one end thereof forming a pair of projecting end portions having beveled ends, a pair of legs having beveled upper ends connected to the beveled ends on the projecting end portions of the mounting plate by a pair of pivot pins, a third leg between said projecting end portions of the mounting plate and connected therewith by a third pivot pin, the three legs folding together side by side in the plane of said mounting plate.
