  • Patent number: 6641676
    Abstract: The fluid-powered scouring whip is a length of flexible tubing composed of rubber or plastic. One or more scouring members, such as bristles or tines, extend outward from the tubing. These scouring members are molded or tooled as integral parts of the tubing, and may be configured in a variety of angles, densities, patterns or lengths. The fluid-powered scouring whip would be attached to a source of rapidly moving fluid. The whip would be introduced into a remote area in need of cleaning, such as an air duct. When fluid was introduced through the fluid-powered scouring whip, the whip would move about rapidly and randomly, scouring the surfaces of the area into which it had been introduced.

  • Patent number: 5109567
    Abstract: A main hose has one end which supports a hub and outward extending tubular members for rotation. Said one end of the main hose has inlet openings and the other end is coupled to a vacuum blower. A second smaller diameter hose extends into the main hose and has one end connected to the hub and the other end connected to a compressor. The compressor is operated to inject air through the second hose and through the rotatable tubular members for rotating the hub and the tubular members and for injecting air outward through the tubular member onto the walls of the duct to be cleaned. The vacuum blower is operated to form reduced air pressure in the main hose to withdraw the loosened material by way of the inlet openings at said one end and through the main hose by way of the vacuum blower.

  • Patent number: 5046217
    Abstract: A blind cleaner for mini blinds has a handle with an operating center at one end. The handle includes connections for a supply of water and detergent under pressure, and for a vacuum line. The operating center includes a nozzle from which water is dispensed, the nozzle being covered by foam for dispersion of the water. Both the water supply and the vacuum are connected to the operating center. There are holes in the operating center for allowing air to pass into the device. The result is that water is dispensed to clean a surface, and the vacuum removes the water and dirt and prevents spilling of water.

  • Patent number: 5030410
    Abstract: A vacuum system for cleaning the base of a control blade guide tube comprises a vacuum source and a novel vacuum head. The vacuum source includes a conventional vacuum pump and filter, for trapping matter entrained in water driven by the pump. The vacuum head is disk-shaped and has an off-axis vacuum port which can scan the guide tube base when the disk is rotated 360.degree.. Elongated slots in the disk admit water down through the disk. Guide fins separate the slots from the vacuum port. The guide fins are shaped to provide a clearance over the guide tube base, effecting a highventuri action which helps sweep up debris on the guide tube base. An annular ridge on the disk surrounds a similar annular ridge on the base, isolating a control rod drive tube housing below the base from the vacuum. This prevents control rod drive components from being disturbed by the vacuum.

  • Patent number: 4995201
    Abstract: A blasting device for cleaning the inner surface of a hot deformed pipe end has a blast lance of inner and outer coaxially aligned tubes which connect with a blast nozzle head having nozzles. Injectors on the inner tube direct carrier medium and abrasive in an annular chamber between the inner and the outer tubes, through the nozzles. An axial pipe coaxially disposed in the inner pipe carrier further carries medium through the blast nozzle head and a deflector attached to the blast nozzle has radially extending passageways that direct the same through the periphery of the blast nozzle head to provide a gas curtain to protect the undeformed pipe section from abrasive. A removeable heat resistant element is attached to the deflector to further protect the undeformed section of the pipe.

  • Patent number: 4800616
    Abstract: The cleaning apparatus is formed by a housing member adapted to be inserted into an air duct and which has two spaced apart ports for providing an air flow path through the housing member. A flexible hose has one end coupled to one of the ports and is employed for moving the housing member in the air duct and for providing a passage for the flow of air from or to the housing member. A turbine formed by blades fixedly connected to a shaft is supported within the housing member for rotation about the shaft upon passage of air through the housing member by way of the two ports. An off centered weight is coupled to the shaft for rotation with the turbine for causing the turbine and hence the housing member to vibrate upon rotation of the turbine whereby the housing member may vibrate against the inside wall of the air duct to loosen dust and other matter from in the duct and to facilitate movement of the housing member in the duct.
