Abstract: An underwater hydraulic connector utilizing a cylindrical male portion inserted into a cavity in a female portion. The male portion consists of a telescoping inner and outer housing with a plurality of resilient seals mounted within openings in the outer housing whereby if the seals are compressed they will extrude beyond the surface of the male portion and contact the interior surface of a female portion so as to provide a sealed passageway between a set of ports in the male and female portions. The extrusion of the seal is accomplished by means of a bar which compresses the seal when moved longitudinally with respect to the outer housing. The bar is mounted on the inner housing. Relative movement of the inner housing and bar with respect to the outer housing is controlled by means of a piston and cylinder assembly and compression of the resilient seals is assisted by the external water pressure acting upon the inner housing to force it into the outer housing.

Abstract: The invention is directed to removable heat exchanger tube assemblies in heavy duty equipment radiators in which the tubes are each separately removable if they become defective in service. An inwardly facing annular ledge or abutment is molded into the inside diameter of each upper and lower sealing member to receive the respective ends of the tubes and prevent vertical movement of the tubes in service. A flange or shoulder is also provided on the lower portions of each tube and engages the inside of the lower sealing member to further restrain downward movement of the tubes in service. Each tube may be removed by pushing the tube upwardly to overcome the upper ledge abutment and thereby lift the tube free of the lower seal. Each tube may then be removed sidewise from the radiator. Variations of the removable sealing arrangement can be made and are described herein.

Abstract: Penetrations or passageways through fire rated or fire resistant walls, floors, partitions, and ceilings are frequently necessary to provide for present or future pipes, cables or conduits. A fitting placed in the penetration provides a seal to prevent the passing of fire, products of combustion, gas vapor or liquid through the penetration under normal conditions and under adverse conditions of fire or elevated temperatures. The fitting includes an elastomeric-like material, under pressure, which provides the initial barrier. An intumescent material, which responds to heat is provided to expand and fill any void created by the degeneration of the elastomeric material in response to the heat or fire. The fitting may include an outer exposed layer of intumescent material to serve as an insulator.

Abstract: An effective, easily installed coupling structure for use in securing a pipe in an opening in a member from one side of the member can be constructed so as to utilize an expandable sleeve. Such a sleeve is initially of a cylindrical configuration and is located around a threaded end of the pipe adjacent to a tapered shoulder on the pipe. The pipe is inserted through such an opening so that the sleeve extends through the opening and so that a flange on the sleeve abuts against the member. A nut is then located around the threaded end and relative rotation is caused between the nut and the pipe through the use of a holding structure on the pipe and the nut. Such action holds the sleeve as the pipe is drawn toward the member. Engagement between the sleeve and the shoulder then expands the sleeve so that the pipe is held as the result of the flange engaging one side of the member and the sleeve engaging the other side of the member.
