Abstract: An additive sub-system for a wastewater management system of a vehicle including at least one holding tank and a toilet has a controller, at least one additive dispenser and a pump. The at least one additive dispenser is in fluid communication with the at least one holding tank or the toilet. The pump is associated with each additive dispenser of the at least one additive dispensers. Each pump is controlled by the controller to dispense an additive from the at least one additive dispenser to the at least one holding tank or the toilet.

Abstract: An apparatus for delivering wastewater from a recreational vehicle to a drain includes a housing having an outer wall and an inner wall generally perpendicular or slightly angled to the outer wall. The housing and the inner wall define an inlet chamber above the inner wall and a further chamber below the inner wall. The housing further includes an outlet downwardly extending from the inlet chamber.

Abstract: A cabled midplane includes a first support plate along a plane between a first connector set and a second connector set that connect to line cards on either side of the cabled midplane. The first connector set and the second connector set include connector slices. A wiring sub-layer includes cable slices to provide a connection between the first connector slice of a connector of the first connector set to the first connector slice of a connector of the second connector set, such that the first wiring sub-layer connects each connector of the first connector set, through one cable slice, to a connector of the second connector set. Additional wiring sub-layers are added, and a second support plate, parallel to the first support plate, is provided to encase and support the wiring sub-layers between the first support plate and the second support plate. Other apparatuses and methods are described.

Abstract: A system, method, and apparatus for obtaining information about an aircraft sighted from the ground. The system includes a communication device for determining an estimated location of the visually acquired aircraft, a flight database for determining information about a specified aircraft based on a provided location, and a network allowing communication between the communication device and the flight database. The communication device provides the estimated location of the sighted aircraft to the flight database and the flight database provides information on the sighted aircraft to the communication device.

Abstract: A laser pick-up apparatus and method for a stringed musical instrument. The laser pick-up includes a laser diode affixed to the musical instrument. The laser diode is capable of generating a laser beam. The laser pick-up also includes a photodetector affixed to the musical instrument adjacent the laser diode. The photodetector is capable of detecting light from the laser beam. The photodetector includes a conversion mechanism for converting the detected light into electrical signals. The laser diode is positioned on the musical instrument to direct the laser beam toward the string. The laser beam is reflected off the string and received by the photodetector. The photodetector then converts the detected light from the reflected laser beam into electrical signals which provide sound to an amplifier.

Abstract: A system and method for propelling a carriage on a cable of a space elevator. The space elevator system includes a cable anchored to a terrestrial body on a first end and a counterweight on an opposing second end and a carriage riding along the cable. The system also includes an oscillator for generating a mechanical wave upon the cable. Mechanical energy created by the generated mechanical wave is converted into power to propel the carriage upon the cable. The oscillator may include a pair of opposing pistons contacting the cable on opposite sides of the cable or an electromagnetic driver powered by electromagnets located on opposite sides of the cable.

Abstract: The present invention relates to a panel comprising two parallel skin plates made of wood or a wood material, between which ribs extend for stiffening the panel, wherein the ribs are at least substantially made of wood or a wood material. The present invention further relates to the use of such a panel as a scaffolding board or a construction element and to scaffolding provided with such panels.

Abstract: A method and apparatus is provided for the continuous extrusion of porous activated carbon block filter elements. The invention includes feeding material into the barrel of a screw extruder and heating the material therein such that the material becomes an agglomerated mass. The agglomerated mass is agitated and compacted into a die where it is cooled to a semi-solidified state. In the semi-solidified state, the material is passed through a cooling tunnel where the material solidifies and the carbon block filter element is formed. A back pressure control device is also included to control pressure in the die.

Abstract: A bag filter assembly utilizing a conventional housing and end cap construction includes a unique filter bag retaining cage and end cap adaptor which allow the use of replaceable bag filter elements of widely varying construction. The assembly will accommodate bag filter elements of the type having a shape retaining opening of rigid construction and including a shape-retaining bottom end cap or of the type comprising a generally continuous flexible tubular sleeve. The system is tolerant of the latter type of bag filters of substantially varying thicknesses.
