Abstract: A method of sealing a sensor assembly from contaminants including inserting the assembly into an overmold, providing a first stage overmold to cover a first portion of said sensor assembly intended to be external to an associated bore, and providing a second stage overmold to cover a second portion of the assembly intended to be disposed in the associated bore.

Abstract: A ported sub treatment system in which well treatment materials are pumped into an uncased portion of a well through a pipe having a number of holes at specific locations along its length such that these materials are able to be distributed as desired by the operator, through these holes, along the length of the well. The treatment system is also able to provide sufficient pressure such that treatment materials are able to penetrate or fracture the rock surrounding the well, if necessary.

Abstract: A ported sub treatment system in which well treatment materials are pumped into an uncased portion of a well through a jointed tubing string having a number of holes at specific locations along its length such that these materials are able to be distributed as desired by the operator, through these holes, along the length of the well. The treatment system is also able to provide sufficient pressure such that treatment materials are able to penetrate or fracture the rock surrounding the well, if necessary.

Abstract: A retrofit assembly for adapting two replacement rooftop air handling units to a multizone installation that originally had only one air handling unit. The two replacement units include one heating unit and one cooling unit, while the original unit typically had provided both heating and cooling to several zones in the building. The retrofit assembly includes a valve manifold and a curb adaptor that make it possible to use the building's existing roof curb and air ducts. The curb adaptor supports the cooling unit on top of the existing roof curb and includes an air duct for conveying air from the existing return air ducts in the building to the inlet of the cooling unit. The heating unit is mounted on its own separate roof curb and the valve manifold receives the air discharged from both replacement units and directs it into the existing plurality of supply air ducts which further convey the air to the plurality of zones in the building.
