  • System, method, and apparatus to retain in-cylinder linear position sensor
    Patent number: 10323662
    Abstract: A system, a method, and an apparatus to retain an in-cylinder linear position sensor in a cavity of a housing of a hydraulic cylinder assembly are described. The in-cylinder linear position sensor includes a sensor body that houses circuitry of the in-cylinder linear position sensor, and a sensor cap that extends from an upper surface of the sensor body. The sensor cap has a retention mechanism with a portion that extends radially outward relative to a central vertical axis of the sensor body so as to extend into and engage a wall of an access port of the housing to hold the in-cylinder linear position sensor in the cavity of the housing. The portion of the retention mechanism is configured to move inward from an outer position toward the central vertical axis of the sensor body.

  • Method for converting a retrograde substance to the gaseous state
    Patent number: 4522183
    Abstract: A method for converting a retrograde substance from a liquid to a gaseous state comprising bringing the substance to a defined initial state of pressure and volume, and relaxing to a defined final state. The defined states correspond to regions on the pressure-volume diagram of the substance, the initial state lying to the lower volume side of a boundary defined by the branch of the critical isentrope lying to the greater pressure side of the critical point, and by the stability limit of the substance. The final state lies to the greater volume side of this boundary.
