  • Patent number: 7793801
    Abstract: A method of pumping liquid from a container to a destination comprises the steps of connecting a foot operable air pump in sealed air-delivery relation to the container; connecting a liquid delivery hose in sealed liquid receiving-relation to the container at the aperture such that the inlet end of the liquid delivery hose is submerged in liquid in the container, the liquid delivery hose having a hand operable valve for controlling the flow of the liquid through the liquid delivery hose; and operating the foot operable air pump by a foot, so as to pump air into the container, and operating the hand operable valve by a hand, so as to cause the liquid to flow from the container, through the liquid delivery hose, and to the destination. A related system, fitting, and adapter are also disclosed.

  • Patent number: 7213820
    Abstract: A mobile load support for cradling and moving heavy loads comprises a pair of axles in spaced apart parallel relationship to each other, having corner units pivotally mounted on respective ends of the axles. Each of the corner units comprises a truck body having swivelable castor wheels disposed at each end thereof, and a platform projecting therefrom at a level below the longitudinal axis of the truck body for cradling a corner of the load. A pair of ratchet straps engages the ends of the axles, and can be tightened to secure the mobile load support around the load. The mobile load support is capable of manoeuvring over uneven surfaces due to the pivoting action of the corner units, which reduces the tendency of the load becoming dislodged from the support, and is flexible in that it can be easily adapted to loads of different sizes.

  • Patent number: 7185920
    Abstract: The invention provides a retractable cover apparatus, which when extended to cover the wheel or track area of a variety of vehicles minimizes the amount of spray and debris flying from the tires or tracks of the vehicle. The cover system is mounted to the frame of a vehicle without requiring extensive modifications to the frame, and includes, for each side of the vehicle, an elongated flexible cover having first and second ends and a width sufficient to extend laterally outwardly beyond an outer extent of the wheels or tracks of the vehicle. The cover system also include at least first and second cover housings, one of the housings adapted to contain the cover in a rolled retracted condition and the other housing being adapted to anchor a free end of the cover in an extended condition thereof. At least one support bar is removably mounted to the frame of the vehicle over which the cover is supported.
