Abstract: A method and apparatus for controlling a compressor system by sensing a temperature of compressed fluid in an outlet of a compressor and automatically reducing an output of the compressor when the temperature exceeds a predetermined temperature and a pressure in the outlet exceeds a predetermined pressure. High and low pressure settings may be provided so that the controller operates the compressor system at the appropriate setting based on the temperature of the compressed fluid in the compressor outlet. The output of the compressor may be controlled by limiting an amount of air permitted to enter the compressor's inlet and/or controlling the compressor's throttle. A three-way valve may also be provided to allow a user to chose between the high and low pressure settings.

Abstract: An apparatus for removing moisture from a hot compressed gas before the gas is delivered to a work tool. The apparatus includes a unitary rigid structure composed of a central core, with a header mounted on each side of the core. The central core includes a recuperator section and an aftercooler section, and the headers define air passages whereby the air passing through the apparatus is first cooled in the recuperator section, further cooled in the aftercooler section, and then reheated in the recuperator section. A water separator is positioned at the location where the gas reaches its lowest temperature, and such that upon reheating, a relatively dry and hot gas may be delivered to the work tool.

Abstract: A high temperature fluid sensor has a fusible detector including a body having longitudinally extending conductors therein. A first portion of the conductors is confined within the body whereas a second portion of the conductors projects from an end of the body. The second conductor portions are spaced-apart to define a void therebetween. A fusible material is engaged with, and electrically bridges between the second conductor portions. A tapered portion of the sensor permits the molten fusible material to flow away from the second conductor portions. The tapered portion terminates in spaced-apart relationship with the fusible material and thus further defines the void.

Abstract: The sensor is formed with a polymer body which confines electrical conductors, with the conductors projecting from opposite ends of the body. The conductors' projections at one end define terminal blades, and at the opposite end are shrouded with, and electrically connected by, fusible material that is molded in place. An electrically inert buffer, formed of the same body polymer, is introduced between the conductors at the opposite end, and the fusible material is deposited about the ends and buffer as a cylindrical shell. A V-shaped notch is formed in the buffer for lockingly-engaging the shell. The body has wrenching flats formed thereabout and tapered pipe threads formed thereon to allow its installation in the wall of a pressure vessel, pipe, or housing, with the fusible-material end exposed therewithin.

Abstract: The Sensor is designed for use in detecting fire, or high temperature in vessels or pipes pressurized with air, gas or liquids. It has a polymer body which confines electrical conductors, and the conductors project from opposite ends of the body. The conductors' projections at one end define terminal blades, and at the opposite end are shrouded with, and electrically connected by, fusible material that has been molded in place. The body has wrenching flats thereabout and tapered pipe threads thereon to allow its installation in the wall of a pressure vessel, pipe, or housing, with the fusible-material end exposed therewithin.
