Abstract: Described is an extendable joint (10,100) for attaching a passenger seat to a cabin floor or support structure. The extendable joint (10,100) exhibits behavior of a rigid mounting during normal usage, such as when carrying or securing passengers or luggage. However, if a force threshold is exceeded, such as with an emergency situation, the extendable joint (10,100) may lengthen to absorb energy applied from the cabin floor through the passenger seat and vice versa. Additional force damping mechanisms may also be incorporated into the joint to further absorb, distribute, or reduce loadings that may otherwise separate the passenger seat from the floor or support structure.

Abstract: A pump having a symmetric end cap is disclosed. The end cap is attachable in a first position or a second position wherein the second position is rotated relative to the housing. A trunnion arm extends in a first direction and a system port opens in a first orientation when the housing is connected to the end cap in a first position. The end cap includes structure such that the housing may be connected in a second position so that the trunnion arm extends in a second direction while maintaining the system port opening in the first orientation. The end cap may be provided with a symmetric porting system. A control device for affecting movement of the swashplate is disclosed. Methods of locking the swash plate into a predetermined position are also taught.

Abstract: An improved burner and a method for combusting fuel in burners used in furnaces such as those found in steam cracking. The burner includes a burner tube having a downstream end and an upstream end for receiving fuel and air, flue gas or mixtures thereof, a fuel orifice located adjacent the upstream end of the burner tube, for introducing fuel into the burner tube, a burner tip mounted on the downstream end of the burner tube and adjacent a first opening in the furnace, the burner tip having a plurality of air flow notches positioned about an outer periphery thereof, a peripheral tile surrounding the outer periphery of the burner tip, forming the first opening in the furnace, and a burner tip seal in contact with at least a portion of the outer periphery of the burner tip and the peripheral tile, wherein a plurality of air gaps is formed between an inner periphery of the burner tip seal and the air flow notches, the plurality of air gaps effective for providing a portion of the air for combustion.

Abstract: A burner for use in furnaces such as in steam cracking. The burner includes a primary air chamber; a burner tube having an upstream end, a downstream end and a venturi intermediate said upstream and downstream ends, said venturi including a throat portion having substantially constant internal cross-sectional dimensions such that the ratio of the length to maximum internal cross-sectional dimension of said throat portion is at least 3; a burner tip mounted on the downstream end of said burner tube adjacent a first opening in the furnace, so that combustion of the fuel takes place downstream of said burner tip; and a fuel orifice located adjacent the upstream end of said burner tube, for introducing fuel into said burner tube.

Abstract: A pump unit having a pump cylinder block mounted in a housing on an end cap. The cylinder block is driven by a pump input shaft, where the input shaft has a first driven end and a second end, and the second end extends through the end cap and out of the housing.
