Abstract: An adjustable support stand supports equipment above a foundation. A rotatable body has a threaded sleeve. A shaft has a support end for supporting the equipment and a threaded end for screwing into the threaded sleeve of the rotatable body. The rotatable body is coupled to a base. The base of the rotatable body can include a vertical channel member which is adaptable to come in contact with a foundation. The rotatable body is operable to adjust a height of the support stand. An isolation bearing assembly is disposed on the support end of the shaft for providing isolation to the equipment. An optional brace apparatus is connectable to the base of the rotatable body. The brace apparatus can include two or more angled legs to stabilize the rotatable body and clear existing structures and obstacles located on a foundation.

Abstract: A fire proofing assembly with friction sliding surfaces to accommodate wide horizontal seismic isolator movements placed around seismic isolators and in partitions at the perimeter of isolation spaces. Heat reflecting, insulating and intumescent layers may be interposed at friction surfaces. Normal force to friction may be maintained by spring. Temporary, partial dissembling arrangement provided for isolation bearing inspection. Elastomeric curtain may be provided for fire hose test.
