Abstract: A process for building a submersible and/or a floating aquatic LED light to attract fish and/or for night diving. An aquatic LED light that has all light house and disco light effect eliminated by wrapping the LED lights in a spiral design and is encased in a electrical isolative transparent material.

Abstract: A water and/or touch activated aquatic light, comprising: a watertight encasing; a battery mounted inside the encasing; a lamp mounted on and/or in the encasing; a pair of electrodes exposed on the exterior; an electronic switch responsive to current flowing through a conductive liquid path between said electrodes; and wherein the watertight encasing is sized and shaped so that the aquatic light floats, sinks, and/or has a neutral buoyancy and is to be used in an aquatic environment where in it may be used as a flashlight, a bait light, a dive light, a lure light, etc.

Abstract: A model corresponds to a collection of source code files. A determination is made that a change has occurred to the model. A sub-set of the collection of source code files is updated or regenerated to reflect the change to the model.

Abstract: An improved slurry pump sealing system that employs a mechanical seal assembly fixed for axial movement with a bearing housing that moves axially to adjust pump impeller clearance. The relative relationship between the seal components remains unchanged regardless of the axial position of the shaft, impeller, and bearing housing. A contraction assembly with interconnecting members contracts to accommodate the reduction of the distance between the pump casing and shaft bearing housing on adjustment of pump impeller-to-casing clearance. In one embodiment the contraction assembly is a telescoping arrangement. In other embodiments, bellows are employed.

Abstract: A filter assembly including a housing and a filter element which includes a bypass/reverse flow valve coaxially disposed within the housing with the filter element and includes a central opening therethrough coaxially aligned with the opening in the filter element through which filtered fluid passes. In the forward flow direction a bypass valve opens responsive to a predetermined pressure differential appearing across the filter element to permit unfiltered fluid to flow from the source to the load without passing through the filter element. In the reverse flow direction, from the load to the source, a check valve closes and applied full load pressure to the reverse flow valve causing it to open with a second differential pressure which is lower than the bypass differential pressure to thereby permit free flow of fluid from the load to the source without passing through the filter.

Abstract: An extracorporeal filter having improved characteristics for the positive elimination of gas bubbles from blood streams. The top of the filter housing is sloped to a high point where there is positioned an air vent. The inlet for the blood is positioned substantially in the center of the top portion and extends past the plane of the top portion into the filter housing.
