The system may include a mounting plate connected to the tow bar, where the mounting plate is pivotably mounted to the frame. The air knife may be supplied with pressurized air to clear the road surface of debris. A guide wheel may be attached to the frame, where the guide wheel is configured to rotate about an axis orthogonal to the plane defined by the road surface.

  • Patent number: 8789237
    Abstract: A blower tube (4) to be connected to a power blower has a tube main body (42) having a distal end portion (42a) diminished in diameter toward its distal end and an attachment (44) to be coupled to the distal end (42a) of the tube main body (42) and including a distal end portion (44a) gradually diminished in diameter toward its distal end. Both these distal end portions (42a, 44a) are each provided three projections at distant position to protrude radially inward toward an axial line of the blower tube (4). The first projections (46) on the tube main body (42) and the second projections (48) on the attachment are positioned offset in phase to align in an alternate order. The blower tube (4) having the projections (46, 48) at the distal end portion can reduce the noise caused by ejection of a high-speed airflow.

  • Patent number: 8756754
    Abstract: A hand carried power tool (100) is presented which includes a vibration-producing power unit (15) interconnected with an elongate handle (20). The handle (20) has a base end (24) coupled to the power unit (15) and an opposite free end (28) configured for manual gripping. Additionally a vibration damping member (50), which permits vibration-induced movement between the base end (24) of the handle (20) and the power unit (15), interstitially located between the base end (24) of the handle (20) and the power unit (15). Furthermore, a resilient biasing member (40) is coupled between the elongate handle (20) and the power unit (15). The biasing member (40) connects to the handle (20) at a location distant from the base end (24) of the handle (20) and the biasing member (40) is configured to dampen vibration-induced relative movement between the base end (24) of the handle (20) and the power unit (15).

  • Patent number: 8671516
    Abstract: The gas-powered dual-hosed blower features two discharge tubes that are each outfitted with a valve that provides for independent adjustment of air speed therefrom. The two discharge tubes have full flexibility, which is associated with backpack blowers so that an end user may direct the air flow in a multitude of directions while simultaneously enabling the end user to adjust the air speed of each discharge tube independently. The valves for each discharge tube are positioned adjacent the blower, and are manipulated by a control stick located on the respective discharge tube. One of the control sticks includes a throttle, which enables adjustment of the engine speed therefrom.

  • Patent number: 8667704
    Abstract: Disclosed is an air knife chamber constructed such that water flowing down along a partition wall is allowed to fall in front of a slit. Due to this construction, the water can be effectively removed by air knives, thus contributing to a reduction in the defective proportion of substrates.

    Abstract: An apparatus for cleaning a surface, such as the surface of a rotating disk, the apparatus comprising an articulating arm associated via a linkage to a rotating member driven by a motor. Rotation of the rotating member causes linkage to move the articulating arm in an oscillating pattern. A nozzle associated with the distal end of the articulating arm can convey pressurized air or liquid from a source to a surface in an oscillating pattern based on the construction of the arm, linkage, the rotating member and the speed of rotation.

  • Patent number: 8631540
    Abstract: A canister attachment for leaf blowers/vacuums is an apparatus that attaches to existing yard waste leaf blower/vacuum's to provide a user with a facilitated means to collect solid animal waste or other debris deposited on the ground. The apparatus comprises a suction nozzle assembly, a canister, a suction duct, a support assembly, and a leaf blower/vacuum. The suction nozzle assembly comprises a canister mount and a nozzle. The canister comprises a nozzle mount, a lateral surface, a filter plate, a duct opening, and a first and second chamber. The suction duct comprises a duct canister mount, a channel, and a leaf blower/vacuum mount. The configuration of these components provides the user with a mobile accessory that utilizes the suction from existing conventional leaf blowers/vacuums to siphon animal waste through the nozzle and into the canister. Furthermore, the apparatus provides an exhaust catch to prevent accidental discharge through the leaf blower/vacuum.

    Abstract: Systems and methods are described herein for cleaning objects, such as refrigeration coils and the like, by placing a first end of a bag over one side of the coils, and placing a second end of the bag over a suction hose of a vacuum. When the vacuum is activated and compressed air (or other gas or liquid) is blown into a second, opposite, side of the refrigeration coils, the dirt removed therefrom is directed toward the interior of the bag and into the vacuum and contained therein. Baffles within the bag direct the flow of dirt and debris toward the vacuum.
