  • Floatable concrete pallet for lifting and bearing heavy loads
    Patent number: 4226203
    Abstract: A pallet having a precast, prestressed concrete grillage superstructure including layers of elongate elements, each successively higher layer being transverse to the layer below it for heavy load bearing objects such as an industrial processing plant. The long elements are not only useful in providing the load-bearing points, but are useful in providing long channels between the elements which are useful as manways and for carrying pipe, conduits and the like that are associated with an industrial processing plant, the heavy load typically lifted and carried by such a pallet. The intersection points or junctions of the elements from layer to layer are load bearing points for distributing in radiating fashion the load placed on the top deck slab of the pallet. The pallet is suitable for transport by a submersible seaworthy vessel located beneath the pallet.

  • Movable threshold door seal
    Patent number: 4198785
    Abstract: A door seal for an inside compartment of a railway passenger vehicle. A door that moves on rollers laterally into and from a door opening to a stored position in a hollow portion of an adjacent wall. The lower portion of the door is located adjacent a threshold having a movable, flexible seal that moves between a flat position covering a roller track portion of the threshold to a substantially upright position against the bottom of the door when the door is located in a closed position. The seal is constructed of a resilient material and bends to be urged against the lower portion of the door in such a fashion as to seal out noise, debris, light and the like. When the door is open the seal returns to a flat, horizontal position to prevent an accumulation of debris or dirt in the door track which would interfere with movement of the door.
