Abstract: A tire and wheel assembly for a forklift type vehicle includes a rim having an annular well to enable fitting of tubeless tires and a tire having an aspect ration of 58% or less. The tire is inflated to a pressure of at least 125 pounds per square inch (psi) and has fabric cross plies extending a distance of at least 30% up the inner face of the side walls of the tire.

Abstract: An air impermeable sealing band of rubberized material is introduced between the patient's stump and the interior of a stump-receiving socket of an artificial limb, in one of two ways, depending on whether or not the patient wears a stump sock. If the patient wears a stump sock, the band of sealant material is impregnated into the stump sock. If the patient does not wear a stump sock, an impregnated sock is incorporated into the interior structure of the socket of the patient's prosthesis. The impregnated sock itself is fabricated by placing a conventional stump sock on a somewhat oversized form. An appropriate annular region on the sock is then masked off by means of tightly fitting plastic bags, and one of the plastic bags provides an enclosing outer sheath which encompasses the annular region and extends upwardly above the form.
