20090194961 | VEHICLE SUSPENSION SYSTEM - A suspension system for a tilting vehicular chassis based on more than three wheels separates a tilting component of the chassis from a non-tilting component. The non-tilting component provides a means for powering the vehicle with automotive-type engine and drive train options, while the tilting component provides the turning stability necessary for a narrower wheel base. The narrower wheel base benefits fuel economy. The multiplicity of wheels, and the breadth of platform thus enabled, permits shelter and comfort features for the occupant not otherwise available on a typical two-wheel chassis. | 08-06-2009 |
20100163644 | ROTARY PROPULSION NOZZLE SET - A self-governing spray apparatus for irrigation or cleaning purposes is provided. A spray nozzle at the end of a moment arm and substantially perpendicular to an axis of rotation creates a reaction torque to distribute a spray by spinning. A hinged member thrust into the spray pattern by means of the centrifugal force caused by the spin deflects a portion of the spray and results in a braking action. An equilibrium angular speed is thereby reached by self-correcting means. | 07-01-2010 |
20100206817 | PORTABLE SETTLING AND DEWATERING TANK - A settling tank for dewatering a thin slurry is provided in a lined portable container and with a disposable filtering means. A novel method of processing the slurry by settlement of the solid phase and removal of the liquid phase in cycles avoids the clogging of the filtering means. The settling tank can be easily transported and dumped without requiring the transferring of residue sludge or the cleaning of equipment. | 08-19-2010 |
20110002769 | CENTRIFUGAL PUMP FOR DE-WATERING - A method of de-watering during intermittent dry running periods with a self-priming centrifugal pump is presented. Centrifugal pumps, as opposed to diaphragm pumps, are advantageous because they are less expensive and can provide greater capacity. The shaft seals are sensitive, however, to frictional heating when water flow is interrupted. In some situations, this fractional heating may desiccate self-priming. The inventive concept provides a continuous stream of pressurized water moving through the pump to cool the seal and sustain priming capability without substantially impairing the ability of the pump to resume wet operation. | 01-06-2011 |
20110110753 | SYSTEM FOR LOADING CARGO - A simplified apparatus is provided to exploit certain unique characteristics of DC winches, whereby two winches may be cooperatively joined to load and unload a light-duty truck. Since the speed and torque are linearly related in a DC motor, it possible to manipulate certain parameters, such as the resistance of the armature and the mechanical leverage applied to the load, to result in a stable dynamic between two oppositely-directed DC-motor winches. The novel concept avoids the need for controls to coordinate the winches, and no installation is required that would otherwise limit the use of the truck for other purposes. | 05-12-2011 |

20130101375 | TRUCK LOADING DEVICE - An apparatus for loading the bed of a pickup truck comprises a brace for supporting a load from the ground, the brace preventing the load from applying weight to the tail end of the bed with damaging consequences while being drawn into position by a winch and cable system. A pallet is used to stage the load on the ground and to provide a structure with a low angle of attack to the brace, the low angle of attack facilitating the transition of the load to the bed by reducing the tipping moment over the brace. | 04-25-2013 |
20140271070 | Pickup Truck Loading System - An apparatus for loading a camper-insert, or other large-volume load, onto the bed of a pickup truck comprises a stiff-leg frame for supporting the load from the ground, the frame preventing the load from applying weight to the tail end of the bed with damaging consequences while the load is being cantilevered into position over the frame by the draw of a winch and cable system. The apparatus uses at least one telescoping leg to lift the rear of the load as part of a novel hoist assembly, which dynamically braces the telescoping leg on a foot while providing minimal interference to nesting the camper-insert closely to the host surfaces. | 09-18-2014 |
