Abstract: A cleaning device and method of cleaning are provided. The cleaning device includes a power source and a pump in selective electrical communication with the power source. A storage container is provided. A valve assembly is disposed in the storage container and in fluid communication with the pump, the valve assembly being configured to selectively flow cleaning fluid from a first portion and a second portion of the storage container. A cleaning element having a spray nozzle is in fluid communication with the pump.

Abstract: A floor cleaning system having a flat headed mop is provided. The system includes a bucket having a wringing assembly. A blade including a first angled portion is provided for that is adjacent a plurality of first openings for compressing the flat headed mop as it is inserted in the wringing assembly to remove dirt and debris accumulated during use. A second angled portion is provided for adjacent a plurality of second openings for compressing the flat headed mop as it is withdrawn from the wringing assembly.

Abstract: A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

Abstract: A method and apparatus for triggering integrated circuit test equipment. More particularly, a method and apparatus for triggering integrated circuit test equipment by detecting photon energy emitted from a switching transistor on the integrated circuit. At the approximate moment in time when the switching transistor operates, photon energy is emitted. The photon energy typically in the form of light, is magnified and converted into an electrical signal. The electrical signal acts as a trigger to initiate the test equipment, such as data recording in the test equipment, at some predetermined time after emission of the photon energy. The recorded data can then be used to test and troubleshoot the integrated circuit.

Abstract: There is provided a process for preparing yarn comprised of at least 83 percent (by weight) of poly(tetramethylene) terephthalate with a spun denier per filament of from about 0.6 to about 50 from a polymer with a relative viscosity of from about 10 to about 50. In said process filaments of said polymer are extruded through a spinnerette at a spinning temperature of from about 240 to about 280 degrees centigrade, and the extruded filaments are taken up at a windup speed of from about 1000 to about 10,000 feet per minute; during said extrusion, the spinning threadline tension per extruded filament (as measured about 70 inches from the face of the spinnerette) is at least 0.09 grams per filament. Thereafter the extruded filaments are drawn in one or more stages to a draw ratio of from about 1.0 to about 5.0 and, during the drawing step, the filaments are passed over a heated object at a temperature of from about 60 to about 180 degrees centigrade.
