  • Publication number: 20090169337
    Abstract: An eccentric fastening device is provided. The eccentric fastening device includes a first threaded fastener, a base and a rotary lug providing a non-fastened pre-assembled position. The base includes a top, a bottom, a stem and a hole, where the stem axially extends from the bottom of the base, and the hole axially extends from the top through the stem of the base. The rotary lug is releasably retained in the hole of the base by the first threaded fastener. The rotary lug includes a cylindrical portion having a thread and a head, wherein the head is offset from the cylindrical portion. The cylindrical portion is substantially axially concentric with the hole of the base, allowing the head to be eccentrically rotated on or off of the stem, whereby a selective structure may be variably clamped and releasably retained between said head and said base. An aircraft having an eccentric fastening device is also provided. A method of installing the same is also provided.

  • Patent number: 7191485
    Abstract: A vacuum sweeper includes a blower for pulling debris in a stream of air through a vacuum duct, past the blower, out a blower discharge duct and into a hopper. Debris settles to the bottom of the hopper and the air exits the hopper through a return air duct having a discharge opening. The discharge opening is positioned near a vacuum nozzle inlet of the vacuum duct such that dust and debris in the return air stream is pulled back into the vacuum duct. The air discharge opening and the return air duct are sized to be larger than the vacuum nozzle inlet. The speed of the air exiting the discharge opening is thereby reduced increasing the percentage of the return air pulled back through the vacuum nozzle inlet instead of being blown out of the vacuum chamber and into the atmosphere.
