Abstract: An improved neck seal having an interior surface being concave throughout and shaped to entirely conform to the circumference of a roll surface of a roll. The concave surface further defines the interior side of an oil-side lip extending upwards from the seal body. A portion of the lips outermost end extends radially downward to form a first stop integral with the lip. A portion of the outermost end of the seal body also extends upward from the top surface thereof to form a second stop integral with the seal body. A v-shaped spring is then disposed in a v-groove defined by the inclined bottom surface of the oil-side lip, and the flat top surface of the seal body. In this manner, the first and second stop retain the spring in a position conducive for a more positive seal contact between the lip of the seal and the roll neck without the use of a garter spring.

Abstract: An article of manufacture for a portable shelter suspended above the ground having a flexible floor supported by a plurality of straps, a flexible framework attached to the floor, a canopy suspended over the framework for enclosing a space; and support means attached to the framework for attaching the shelter to a plurality of load bearing members. The floor may be further supported by rigid support poles made of PVC placed within a fold sewn along the shorter length of both ends of the floor. The floor may be further supported by diagonally crossing support straps under the floor. In another preferred embodiment, the floor may be rigid.
