Abstract:
The present invention provides an apparatus that is used to measure relative humidity, such apparatus comprises a housing having a first end and a second end. There is a humidity sensor disposed at the first end of the housing for measuring the humidity in the air and a temperature sensor also disposed at the first end of the housing for measuring ambient temperature. The apparatus has an electronics portion in direct electrical communication with the humidity sensor and the temperature sensor for computing a relative humidity and a dewpoint temperature. The electronics portion is disposed within a center portion of the housing. There is, further, a battery that is in electrical communication with the electronics portion, the humidity sensor and the temperature sensor for providing power to the apparatus. Such battery is disposed in the center portion of the housing of the apparatus. The apparatus has a display means that is in electrical communication with the electronics portion and with the battery for displaying such relative humidity and such dew point temperature as determined by the electronics portion. The display means is disposed at a second end of said housing.
Abstract:
A valve seal system for passageway through a valve body emerging through a first generally flat and rigid surface, having a valve member including a resilient seal with generally flat exposed surface adapted to be brought into contact with the generally flat rigid surface, and having a generally circular, raised resilient ring portion extending from the generally flat exposed surface, the raised resilient ring portion adapted to be compressed against the generally flat rigid surface to seal the resilient seals against the generally flat rigid surface when said valve member is moved to a closed position by virtue of the raised resilient ring portion being compressed against the generally flat rigid surface.
Abstract:
A desiccant canister assembly for use in an air dryer system includes a pair of concentrically disposed casings, top and bottom end caps, top and bottom porous plates and moisture absorbing material. A cylindrical opening is defined in between the casings. The top end cap affixes to the upper ends of the casings. The bottom end cap affixes to the lower ends of the casings. Each end cap features openings that allow air to flow through the cylindrical opening. The bottom porous plate is situated at a bottom of the cylindrical opening against the bottom cap. The top porous plate is slidably disposed within the cylindrical opening near the upper ends of the casings. The absorbing material is disposed within the cylindrical opening between the porous plates. The desiccant assembly also includes a mechanism for compacting the absorbing material between the porous plates. The desiccant assembly further includes a mechanism for aligning and securably retaining the desiccant canister assembly within a canister housing of the air dryer system. The latter mechanism includes a positioning bore defined within an inner one of the casings and through a center of each end cap. The positioning bore receives a threaded rod extending from a center of an upper base of the housing about which the desiccant assembly securably retains through a lock washer and a stop nut so that an outer ring portion of the top cap aligns with and seals via an o-ring against a sealing flange of the housing.
