Abstract: A removable mattress cover assembly includes a removable mattress cover that attaches to an upright wall assembly. The upright wall assembly includes an upright wall that attaches to a top of a mattress base and one or more wall fasteners attached at or near the top of the upright wall. The removable mattress cover includes cover fasteners that mate with respective wall fasteners to attach the cover to the upright wall. When the cover fasteners are attached to the wall fasteners, the removable mattress cover lays over the top of the mattress base, and the upright wall is nearly perpendicular to the removable mattress cover. This allows a fill material that is nearly the same size as the top of the mattress to be inserted beneath the removable mattress cover. The fasteners can project upwardly, away from the top of the mattress base, making the fasteners easily accessible from above.

Abstract: An electrosurgical instrument for selectively providing electrical energy from an electrosurgical generator to an electrode blade for searing and coagulation is provided. The instrument comprises a hollow body having a first and second hollow area and a cable connected to the generator having a main contact wire and first and second switch wires with a main conducting strip connected electrically to the blade. First and second switch conducting strips are selectively connected to the main conducting strip. A receiver receives the blade and is electrically connected to the main contact wire to provide electrical connection between the contact wire and the blade. The blade extends from the first hollow portion with at least one plume intake port formed in the body receiving the surgery associated plume into the first hollow portion.

Abstract: A method of providing a suspended ceiling in a storage tank involves building a deck on the floor of the storage tank and raising it into place by using an external hoist mechanism. The hoist mechanism is connected to the deck by cutting holes in the roof of the tank and feeding cables through the holes. The cables are attached to a series of extenders, such as metal bars, that are fixed to lift points on the deck. The extenders are long enough so that, once the ceiling is raised to its final position, portions of the extenders project into the holes in the roof. The ceiling is then fixed in position by securing the extenders to the roof. After the ceiling is secured in position, the holes in the roof are sealed.
