Abstract: A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

Abstract: An insect capture device is used to monitor, capture, and/or kill insects. The device has a raised portion to create a gap between a surface and the device to entice insects to pass under. At the raised portion, a glue board includes an adhesive facing the surface. As the insect passes under the raised portion, the insect can unknowingly become attached to the adhesive portion and stuck thereto. To aid in installing the glue board, one or more sections of the glue board can be free of adhesive to connect or fit to a part of the device to hold the glue board in place, while also allowing for easy removal to replace the glue board with a new one, free of captured insects.

Abstract: A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

Abstract: A solid product dispenser can be used to form a dilute liquid solution from a block of solid concentrate. In cases where only a small amount of liquid solution is needed, the solid product dispenser may dissolve the block of solid concentrate quickly and substantially uniformly to provide a solution of controlled concentration. This can be contrast with larger dispensing applications where a dispenser may dissolve a block of concentrate slowly at the start and more rapidly as the dispensing progresses, producing a solution with an average concentration higher than if only a small amount of solution were produced using the dispenser. In one example, the solid product dispenser includes a fluid distribution reservoir and a solid product reservoir positioned inside of the fluid distribution reservoir and over a platform on which the solid product sits. High pressure fluid flows between the two reservoirs, turbulently contacting the solid product.

Abstract: A drainage component in fluid communication with the fluid supply line includes a drain channel leading to a drain, the drain channel having an inner wall and an outer wall. The inner wall has a sealing surface approximate a three-way elastomeric valve. The elastomeric valve includes a moveable first wall having a first position when the fluid supply is on and a second position when fluid supply is off and a second wall connected to the moveable first wall, the second wall engaging a drain sealing surface when the first wall is in the first position. The elastomeric valve includes an orifice through which fluid may flow. When the pressure of the fluid on the elastomeric element increases, the second wall of the elastomeric valve engages the drain sealing surface. The elastomeric valve is preferably a fluoroelastomer to ensure both flexibility and resistance to a variety of chemical products.

Abstract: A pressure transmitter system for measuring a pressure of a process fluid in an industrial process includes a pressure transmitter having a pressure sensor. A process fluid passageway having a circular opening is configured to couple pressure of the process fluid to the pressure sensor. A concentric seal support structure extends around the circular opening comprising an annular recess. An annular stress riser is positioned radially inward from the annular recess. A seal material fills the annular recess and contacts at least a portion of the annular stress riser.

Abstract: A process transmitter housing assembly includes a housing and a cover assembly including a cover chassis and a transparent cover piece. The cover chassis includes a cover flange extending inward from a perimeter of the cover chassis. Internal threads of the cover chassis threadedly engage external threads of the housing. The transparent cover piece is mechanically clamped between the cover flange and a surface of the housing nearest the cover flange when the cover chassis is threadedly secured to the housing.

Abstract: An environmental seal between two compartments, such as in a process transmitter, linked by a passageway contains an electrical cable. The seal includes a stop, a cable gland body, a compression bushing, a cable gland nut, and a first elastomeric seal. The stop projects from an interior surface of the passageway. The cable gland body is in contact with the stop and encircles a portion of the electrical cable.
