Abstract: A filter for a vehicular sewage system that includes an elongated body having a plurality of longitudinal vanes and slots. The body is made from a material able to support the growth of biological agents. The slots sized to resist the passage of particles larger than about 0.04 inches. The filters are structured for use with a vehicular sewage system having a treatment tank divided into an upper chamber and a lower chamber by a membrane. The membrane has a plurality of filter openings in which the filters are disposed. The filters allow fluid waste and solid particles smaller than about 0.04 inch flow into the lower chamber. Larger particles of solid waste are exposed to air in the upper chamber thereby allowing aerobic biological agents to process the solid waste. In use, the filter allows the liquid portion of wastewater to pass from an upper chamber of the treatment tank into a lower chamber. The solid waste particles are then consumed by an aerobic bacteria in the upper chamber.

Abstract: Mobile fluid delivery systems and methods are disclosed. The disclosed embodiments are particularly useful for spraying herbicides on a roadside shoulder. The systems include nozzles mounted upon a movable arm extending from a vehicle. A sensor mounted upon the vehicle detects objects which the extended arm is approaching, such as telephone or other utility poles on the side of the road. The sensor signals a control unit, which directs retraction of the movable arm to avoid collision with the object, and extension of the arm after passing the object. In targeted fluid delivery, the control unit can direct forward fluid spray to the backside of the object as the extended arm approaches, lateral fluid spray as the arm passes the object, and rearward fluid spray to the front side of the object as the arm is extended after passing the object. The system can thus effectively douse the ground surrounding a utility pole, for example, with herbicide and reduce fire hazard.

Abstract: A mobile system for delivering a fluid to a fluid application area includes a vehicle, an arm carried by the vehicle and movable between a retracted position and an extended position, a fluid delivery system carried by the vehicle and including at least one fluid delivery device coupled too the arm, a mechanism for maneuvering the arm between the retracted position and the extended position, a sensor mounted on the vehicle for sensing the approach of an obstacle in the path of the arm, and a control circuit responsive to the sensor for causing the arm maneuvering mechanism to retract the arm towards the retracted position when the sensor detects an approaching potentially interfering obstacle and for extending the arm towards the extended position when the relative positions of the arm and the obstacle are no longer potentially interfering. A safety breakaway mechanism is incorporated into the system for enabling the arm to deflect when struck by an undetected obstacle.

Abstract: A tank isolation valve assembly for use in an effluent discharge path to provide a vapor barrier to prevent back flow of gases while enabling fluid and solid substances to pass through in a desired flow direction. The assembly includes a main housing having an apertured outlet wall structure with an internal surface defining a valve receiving region, a second member coupled to the main housing and having an apertured wall structure with a valve member retaining surface facing the valve receiving region, and an isolation valve member. In one embodiment, the second member is a mating inlet housing with an inlet for connection to an effluent discharge port, and the main housing has an outlet port and a valve chamber. In another embodiment, the second member is a valve plate with a dished peripheral portion in sealed contact with a portion of the inner surface of the main housing. The isolation valve member is a flexible diaphragm mounted in the valve chamber in sealing relation therewith.

Abstract: A variable temperature electronic faucet water supply system provides a plurality of preset water temperature settings from which the user may select a desired water temperature by pressing a temperature selection button. If no water temperature is selected by the user, the faucet automatically delivers water at a default temperature setting. The faucet water supply system includes a motion detector mounted in the head of the faucet which will detect motion near the faucet head. The water is delivered from the faucet head at the preselected temperature when motion is detected near the faucet head. Water is delivered at the preselected temperature for up to two seconds after motion is last detected near the faucet.
