Abstract: A method of fabrication of an emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The shelter is preferably fabricated by vacuum forming a top sheet and a bottom sheet of ⅛ inch acrylic sheet on molds to form top and bottom sections which are then sprayed with an epoxy-fiberglass composition for reinforcement.

Abstract: A method of installation of an emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. In the preferred embodiment, the shelter is placed prior to the pouring of a slab foundation. In an alternate embodiment, the shelter is placed prior to building the floor in a pier and beam foundation.

Abstract: An emergency shelter to be used under the floor of a residential or commercial structure. In the preferred embodiment, a prefabricated acrylic shelter is sized to accommodate at least one individual in a crouching or sitting position. The shelter is placed prior to the pouring of a slab foundation or the building of the floor in a pier and beam foundation. The unit is sealed to prevent moisture infiltration and provides the benefits of a relatively pleasant surface without the accumulation of moisture. Additional advantages are the relative lower expense, light weight, and ease of installation of the prefabricated shelter. Other uses of the shelter include security and storage.

Abstract: A jet bath designed to use minimum water, to use a formed in place low cost waterfall type water inlet, to have pulsating and massaging air-water jets appropriately located in the tub, to allow user adjustment of water temperature, to prevent heating the water above 122 degrees Fahrenheit and prevent tripping of a manually resettable high temperature limit switch with initial filling of the tub with overheated water.

Abstract: An apparatus for discharging a moving fluid stream into a spa tank or the like for subjecting a user's body to the massaging action of the stream, the apparatus having a substantially rigid guide means mounted to the housing of the device which reciprocates between two positions in response to the movement of the fluid stream.
