  • Patent number: 8118943
    Abstract: A self-propelled robotic pool cleaner (100) has a first pair of driven brushes (12, 14) and second pair of free brushes co-axially mounted for rotation on axles (16) at the opposite ends of the pool cleaner that are transverse to the direction of movement. The first pair of brushes are mounted on one side and are driven by a drive motor (110); the second pair of brushes are mounted on the opposite side of the cleaner. A rotational delay clutch (30) is co-axially positioned between each pair of the first and second brushes so that reversing the drive motor causes the first pair of driven brushes to temporarily rotate at an angular rotational velocity that is greater than that of the second pair of brushes, thereby pivoting the pool cleaner through a predetermined angular change in direction before the synchronous rotation of the second pair of dual brushes is initiated by the engagement of the clutch.

A guide has a distal portion that engages a cleaning tool from insertion until a cleaning portion reaches the rear of the passageway. A cleaning tool deflector positioned at the rear of the passageway biases the cleaning tool from the distal portion of the passageway to a proximate portion so that the cleaning portion contacts the ROS window. A unidirectional cleaning feature ensures that the cleaning portion will contact the ROS window during removal of the cleaning tool by preventing re-insertion of the cleaning tool in the proximate portion of the passageway.

A first conveyor module is provided that is mountable to the conveyor support structure of the vehicle wherein the conveyor is configured to transport debris from the broom assembly to the hopper on a continuous belt having paddles. A second conveyor module is also provided that is mountable to the vehicle structure wherein the second conveyor is a squeegee type conveyor. The first conveyor module and the second conveyor module are interchangeable on the street sweeping vehicle. Because the size envelope and attachment points and mechanisms are common, the two modules can be interchanged at will.

  • Publication number: 20110297185
    Abstract: The present disclosure relates to particles comprising carboxyalkyl starch that are permeated with an acidic gas and their uses as absorbent materials. It was discovered that superabsorbent materials could be obtained from carboxyalkyl starch particles permeated with the acidic gas and heated to a temperature of at least 100° C. until they reach an AUL at 0.7 psi. of at least 14 g/g and a CRC of at least 18 g/g. Moreover, it was discovered that the pH of alkaline starch extrudates can be adjusted by permeating particles of the extrudate with the acidic gas even with treating the particles to temperatures less than 100° C. The carboxyalkyl starch particles obtained by the methods described herein are characterized as having intramolecular ester bonds, which are greater in number at the surface of the particle than in the core, and the particles have a greater concentration of cation of the acidic gas at the surface than a the core.

  • Publication number: 20110297184
    Abstract: Methods and apparatus for the removal of foreign matter, such as oil and dust, from the end faces of optical fiber and optical fiber connectors. Cleaning is effected by bringing carbon nanotube material into contact with an end face to create a differential adhesion in the proximity of the end face that more strongly attracts foreign matter residing on the end face to the carbon nanotube material than its attraction to the end face. The carbon nanotube material is applied with cleaning swabs or tapes that are used to clean end faces with swiping actions.

  • Patent number: 8070883
    Abstract: Methods and apparatus for removing particles from vials includes the use of a one sided pressure sensitive filament tape to remove external particles from vials. A roll of tape is juxtaposed relative to a line of vials moving along the production line. As each vial moves within the space between the tape the outside of the vial contacts the tape causing the particles to be removed and imbedded in the adhesive on the tape. A feed roll and a rewind roll provides for the tape to unwind while in contact with the outside of the vials and in conjunction with the movement of the vials along the production line. By causing the feed roll and the rewind roll to advance unused tape while in contact with the outside surface of the vials, the vials are caused to rotate at least 360 degrees while advancing down the line.

  • Publication number: 20110284025
    Abstract: An apparatus for cleaning the touch or display touch or display surface of an electronic device such as a cell phone or computer tablet comprising a wiper coupled to cleaner bar. The cleaner bar moves longitudinally and/or laterally across the electronic device with the wiper in contact with the touch or display surface. The wiper comprises both a moist pad and a dry pad. The moist pad is fluidly communicated to a reservoir defined within the cleaner bar. On its “cleaning stroke”, cleaning fluid is released into the moist pad and then deposited onto the touch or display surface. The cleaner bar moves longitudinally across the touch or display surface by manual or motorized means. The cleaner bar may also be in communication with the electronic device to detect when a task has been completed on the electronic device. After detection, the cleaner bar automatically traverses the touch or display surface, thereby cleaning it after every use.
