Carpet cleaning apparatus includes a cleaning wand having a vacuum head and an elongated member forming a passageway for transporting material removed from a carpet by the vacuum head. A cleaning liquid spray nozzle is located at the front of the vacuum head and another cleaning liquid spray nozzle is located at the back of the vacuum head. Two control valves are attached to the elongated member, each controlled by a separate moveable handle, allowing the operator to selectively spray in front or in back of the vacuum head as desired.

A UV air cleaning and disinfecting system has an enclosed chassis with an inlet / outlet surface panel on one planar side thereof, and the chassis is mounted in the space behind a drop ceiling with its surface panel coplanar with the ceiling surface and facing into the room space. The surface panel has a pair of inlet vent arrays on opposite longitudinal sides of the surface panel from each other, and a pair of outlet vent arrays on opposite latitudinal sides of the surface panel from each other. Arranged in the chassis are an air blower unit and an array of UV lamps. The positioning of the inlet and outlet vent arrays establish four mutually circulating air streams in a four-leaf-clover pattern in the room space, which obtains a high-efficiency throughput of air handled by the system. The UV lamp array is arranged longitudinally across the chassis between the inlet ventsat a lower elevational position ofthe chassis. A pair of air filters is arranged at intake chambers separated by UV-blocking baffles at opposite longitudinal sides of the main chamber housing the air blower in the center of the chassis at an upper elevational position from the array of UV lamps. The upward and downward movement of the air through the filters and over the UV lamps toward the center causes swirling movements which enhance the exposure of pathogens in the air to UV radiation exposure. The surface panel is formed with a series of cascading door sections to allow wide access across the center of the chassis for maintenance of the UV lamps, with a first door section connected to an interlock switch for cutting off electrical power to the UV lamps and fan when the first door section is opened. The UV-blocking baffles have an angled shape and slits at an upper flange thereof covered with fused silica shields. The system's chassis is dimensioned to fit on ceiling rails spaced at standard 4 foot length and 2 foot width intervals. The system can provide 99% or higher inactivation of pathogens in the air with 2 to 7 or more air changes per hour for standard sized rooms.

A method and apparatus for fluid treatment of a selected interval of a well and then cleaning the selected interval and the apparatus of treatment residue. An straddle tool is run into the well to treatment depth on fluid supplying tubing and has upper and lower packers that establish sealing with the casing and define an annular interval between the packers and between the tool and casing. Fluid, such as fracturing fluid, is pumped through the tubing to the tool and is diverted through an outlet port of the tool into an upper portion of the annular interval. Fluid then flows from a lower portion of the annular interval through an inlet port below the outlet port and at low flow rate is dumped into the casing through a pressure responsive dump valve. The outlet port and inlet port are located to accomplish cleaning of residue from the packers.

A machine for cleaning cartridge filters used in pool filtration systems. The machine has a cleaning chamber which holds an adjustable tail stock assembly with a first cone and a second cone mounted onto a power-driven motor. The cones are pulled apart to accommodate a dirty cartridge filter. One end of the cartridge filter is placed against the second cone, and the first cone, which can be spring-loaded, is pressed against the other end of the cartridge filter. The cartridge filter is then locked in place. The power-driven motor spins the second cone, while heated water is injected into and through the hollow shafts of the tail stock assembly and the first cone, and into the perforated tube of the cartridge filter, where centrifugal force causes the water to leave the tube of the cartridge filter, carrying away dirt deposits on the surface of the cartridge. A row of spray nozzles can be used to rinse the cartridge filter. The used water is filtered, reheated, and recirculated back into the cleaning chamber.

An upright vacuum cleaner includes a nozzle assembly having an intake opening. A handle assembly is pivotally connected to the nozzle assembly. The vacuum cleaner also includes a suction generator and a dirt collection vessel. In addition, the vacuum cleaner includes a flexible, electrified hose such as a stretch hose.

A self-cleaning floor assembly is configured to form or be positioned on a floor of an enclosed space. The self-cleaning floor assembly includes a moveable floor including a moveable floor panel, an actuation system that is operatively coupled to the floor panel, and a cleaning system proximate to at least a portion of the moveable floor. The actuation system is configured to move at least a portion of the floor panel into and through the cleaning system during a cleaning cycle. The cleaning system is configured to clean the portion(s) of the floor panel during the cleaning cycle.

An invertible multi-layer moisture management fabric pad has a top layer, a bottom layer, and a plurality of overlying moisture-absorbent intermediate layers located between the top and bottom layers. The bottom layer is joined to the top layer along a perimeter of the fabric pad. The moisture-absorbent intermediate layers are adapted for receiving and dispersing moisture entering the fabric pad. The pad perimeter defines an access opening for accessing an inside of the fabric pad. A pull strap is located inside the fabric pad, and is adapted for being grasped by a user reaching through the access opening formed with the perimeter. The pull strap is pulled back through the access opening to invert the fabric pad for laundering.

A moisture management incontinence pad is adapted for placement within an undergarment worn by a user. The fabric composite includes a plurality of overlying absorbent layers having respective first and second opposing end edges and first and second opposing side edges. The adsorbent layers are substantially unattached to one another along at least one of respective first and second side edges and first and second end edges to promote circulation between the layers during laundering.

A medical valve assembly including a rigid external housing and a valve stem of a resilient material. The valve stem includes a passageway for conveying a fluid which has an hourglass shape to create a venturi effect when cleaning the valve stem to improve the efficiency of the cleaning process. The passageway also includes no sharp edges, thus reducing the risk of fluid getting trapped inside the passageway when the medical valve assembly is not in use. Even further, when a needleless syringe is removed from the valve stem, the valve stem expands to an uncompressed state with its top end being generally flush with an end of the housing to present a swabable surface for cleaning purposes.
