  • Patent number: 4635672
    Abstract: There is disclosed a vent for venting air from a system of the type which conducts fluid under pressure. The vent includes a chamber, a ball valve within a top wall of the chamber, and a float within the chamber which is arranged for vertical movement therein. A lever which carries a valve ball element is arranged for pivotal movement against the inner surface of the chamber top wall for disengaging the ball element from the valve when the valve is opened. When the valve is opened, the lever and ball element fall away from the valve. When the vent closes, the float acts upon the lever for guiding the ball element into seating relation with the vent valve.

  • Patent number: 4545397
    Abstract: A float valve assembly capable of operating as a steam trap for discharge of fluid from a system wherein a float operates to open and close an orifice located in a valve seat, the valve assembly being adapted to be easily converted for use in either horizontal flow lines or vertical flow lines by altering the relative position of internal components of the system.

  • Patent number: 4440144
    Abstract: Heater apparatus is disclosed having a metal firebox in which fuel is burned and an outer ceramic enclosure having ceramic mass walls which absorb excess heat when the heater produces more heat than is required and distributes the heat gradually by radiation after the heater output becomes less than the heat stored in the ceramic mass. The ceramic mass walls are spaced from the metal firebox walls to provide air passages through which air may be circulated by means of a blower so that rapid heating may be had of the interior space when the firebox is initially fired by transferring the heat radiated from the metal walls directly into the room by forced convection. After the interior space is heated to a desired temperature, the blower may be cut off and the room may be heated more slowly at a more even temperature by radiation from the ceramic mass.

  • Patent number: 4300719
    Abstract: The disclosure relates to an improved temperature responsive control arrangement. It includes a valve member, a chamber, and a bellows disposed in said chamber for controlling the position of the valve member in response to the temperature of fluid flowing through the chamber. The arrangement is particularly suited for use in steam traps. There are surfaces in the chamber for distributing fluid flowing through the chamber around the bellows to promote rapid expansion and contraction of said bellows with changes in temperature of the fluid flow through said chamber. The chamber has an outlet centrally located at one end thereof, and the distributing surfaces include a plurality of fluid inlets at the end of the chamber opposite from the outlet, the fluid inlets being distributed about the periphery of the chamber.
