  • Patent number: 8061373
    Abstract: The surface cleaning apparatus is provided in self-propelled embodiments and in a trailer embodiment. The apparatus draws liquid from a supplied tank. Liquid is pressurized to approximately 4,000 psi, then directly to the surface to be cleaned. All cleaning and cleaning component functions are powered via the same fluid pumps via a supply manifold. Total width limitations dictated the design of the sidewalk capable apparatus.

  • Patent number: 7940063
    Abstract: A coordinate detecting device includes a resistive film disposed on a quadrangular substrate; a power source for applying a voltage to the resistive film; four electrodes connected to the power source and disposed in four corners of the resistive film; four switches each disposed between the power source and a corresponding electrode; four ammeters for measuring currents flowing through corresponding electrodes; and a grounded conductive film for detecting coordinates of a contact point on the resistive film when the conductive film is brought in contact with the resistive film. The voltage is applied sequentially to the electrodes by opening and closing the switches. When the conductive film is brought in contact with the resistive film, the ammeters sequentially measure currents flowing through the corresponding electrodes. The coordinates of the contact point are detected based on positions of the electrodes and resistances obtained using the measured currents.

  • Patent number: 7600698
    Abstract: The invention relates to a cleaning head for enabling pressurized cleaning liquid to act upon a surface to be cleaned, comprising at least one spray arm which is rotatably mounted about an axis of rotation and on which is mounted at least one nozzle which can be fed with cleaning liquid by a pressure pump. The invention also relates to a surface cleaning device comprising said type of cleaning head. In order to further develop the surface cleaning device and the cleaning head in such a way that the surface cleaning device can be handled more easily, the invention proposes that the pressure pump is integrated into the cleaning head.

  • Publication number: 20090120473
    Abstract: An industrial cleaning system that produces and distributes an aqueous ozone solution is described. The system provides a centralized system for producing the aqueous ozone solution and distributing the aqueous ozone solution to different application points at different flow rates and concentrations. The system includes an ozone generator for generating ozone gas, which is injected into a supply of water to form the aqueous ozone solution. A reaction vessel receives the aqueous ozone solution from the injector. The reaction vessel reduces the bubbles of ozone gas in the aqueous ozone solution to increase the oxidation reduction potential of the aqueous ozone solution.

  • Patent number: 7513264
    Abstract: An engine and high pressure pump are mounted onto a wheeled chassis. High pressure water is distributed to a rotating wand and nozzle assembly on the wheeled chassis so that as the chassis is moved along a linear path, high pressure water is sprayed onto an underlying surface to clean the surface. Optional diffusion plates may be used to prevent high pressure water from being sprayed directly onto the underlying surface in part of the rotational path defined by the wand and nozzle assembly.

  • Publication number: 20030111099
    Abstract: An automotive vehicle washing system includes a frame comprising a bridge member end opposed and support sections mounted for linear reciprocating movement on spaced apart support rails. Pivoting washing nozzle support arms are mounted on the bridge section and are interconnected by a drive motor and drive pulleys to move in opposite directions to wash the sides and opposite ends of a vehicle. Each arm includes movable arm sections supporting spaced apart nozzle assemblies which may move toward each other or away from each other to size a vehicle according to its width. Each arm includes opposed elongated beam members which also provide fluid conducting passages for conducting washing fluids to the nozzle assemblies. Certain ones of the nozzle assemblies are drivenly connected to an oscillating servomotor. The servomotor is also used to position the pivoting arm sections through a lost motion coupling and a gear drive unit.

  • Patent number: 6021793
    Abstract: A method and apparatus for cleaning and rinsing the interior surfaces of a railway tank car with a single, high-pressure fluid spray. The apparatus is inserted into a tank car through its manway and secured using a lockdown assembly. The swivel assembly includes a swivel shaft which is disposed longitudinally through a swivel housing and is interconnected with a rotor motor and with a hollow spindle assembly. A fluid channel communicates the fluid to the spindle assembly where the fluid is sprayed through a single nozzle onto the interior surfaces of a tank car. Control of fluid spray orbit is accomplished by two perpendicular axes for causing rotation and actuation of the nozzle affixed to the spindle assembly, through the cooperation of an idler gear.

  • Patent number: 5979471
    Abstract: Apparatus for removing a liquid (2) containing suspendible solid matter from a tank (1) comprises a plurality of nozzles (47) located at the lower region of the tank. A pump (10) removes the liquid and ejects it through the nozzles (47) to cause resuspension of settled solid matter. When sufficient resuspension has occurred, the tank (1) is emptied by opening a valve to remove a portion of the liquid being transferred to the nozzles (47). The nozzles (47) are arranged as oppositely facing pairs ofjet nozzles at the lower end of a rotatable vertical pipe (46). The pump (10) is suspended by a cable (13) connected to a drum (19) which can be rotated to raise or lower the pump. A pump outlet (12) is connected to a flexible hose (27) which is wound around the drum (19) or around a separate drum (110). A movable containment flask (14) houses the drum (19) and accommodates the pump (10) when withdrawn from the tank (1).
