  • Patent number: 8347859
    Abstract: A method of calibrating throttle controls in an electronic shift and throttle system includes opening the throttle and then moving the throttle back towards a hard stop in increments. The voltage level of an electrical signal sent by a throttle position sensor is measured and recorded at each increment. An idle position is established as being where the lowest voltage level was measured when the throttle is at least 0.75° away from the hard stop.

  • Patent number: 8336268
    Abstract: There is provided a floor drainage assembly for inhibiting water from passing from an upper floor of a building to lower floors of the building. The floor drainage assembly includes a stairwell drain and a stairwell trough connected to the drain. The stairwell trough extends along the stairwell threshold. Water from the upper floor entering the stairwell threshold is at least partially captured by the stairwell trough and directed to the stairwell drain. The assembly inhibits the water from damaging lower floors thereby. An angled threshold plate that is isosceles trapezoid shaped in cross-section may extend across the stairwell drain. The floor drainage assembly may also include a hoistway drain and a hoistway trough extending along the hoistway threshold. Water from the upper floor entering the hoistway threshold is at least partially captured by the hoistway trough and directed to the hoistway drain.

  • Patent number: 8282827
    Abstract: A method of producing methane, an organic based fertilizer and usable water from animal waste includes the step of separating the animal waste into liquid waste and solid waste. The solid waste is subjected to anaerobic digestion to produce methane and a wet by-product. The wet by-product is pressed to into a filter cake which is pelletized into the organic based fertilizer. The liquid waste is clarified to produce a supernatant and a sludge which is pressed into a filter cake together with the wet by-product. Ammonia is extracted from the supernatant to produce ammonium sulfate and an aqueous solution. The aqueous solution is filtered to produce a concentrate and water filtrate. The water filtrate may be used as drinking or washing water. The ammonium sulfate and concentrate may be used to supplement to the solid waste which is pelletized into the organic based fertilizer. In alternative embodiments a portion of the supernatant and aqueous solution may be used as a liquid fertilizer.

  • Patent number: 8251380
    Abstract: There is provided a walker apparatus having a brake, a braking handle, a brake wire, a brake rod, and a brake rod assembly. A gripping member connects to the brake wire. The gripping member includes a plate having a first end, a second end and an aperture near the second end. The plate connects to the brake wire near the first end and the plate slidably receives the brake rod through the aperture near the second end. The gripping member includes a clamp that engages the brake wire via a set screw. The gripping member is spring-biased to remain free of the brake rod in a non-actuated mode. When the braking handle actuates the brake wire, the plate tilts with the first end elevating relative to the second end, thereby causing the plate to engage with and abut the brake rod for thereby actuating the brake rod to brake.

  • Patent number: 8205348
    Abstract: The present invention relates to a removable tile spacer for enabling even spacing between a first tile and a second tile that are perpendicular to each other. The second tile has an end opposite the first tile. The removable tile spacer includes a first elongate member interposable between the first tile and the end of the second tile to provide spacing between the first tile and the second tile. The tile spacer includes a body. The first elongate member is connected to and extends away from the body at an angle relative to the body such that the body has at least a portion which is spaced-apart from both the first tile and the second tile when the first elongate member is interposed between the first tile and the end of the second tile. This thereby facilitates removal of the tile spacer when tile spacing is completed.

  • Patent number: 8141789
    Abstract: A method of controlling the temperature of a food preparation or sanitation appliance includes sensing the actual temperature of the appliance. When the temperature of the appliance is greater than a maximum threshold temperature, a compressor which supplies pressurized air to a burner is shut-off and a flame sensor, which senses the presence or absence of a flame, is overridden so the appliance acts as if a flame is present. When the actual temperature is less than a minimum threshold temperature, the compressor is started.
