  • Patent number: 8925579
    Abstract: A pressure relief valve for use with flexible containers is disclosed. The valve comprises a valve chamber, a valve chamber seat with an inlet gas port or ports to the interior of the container and a resilient diaphragm floating within the chamber. The valve seat is shaped with a generally flat diaphragm-engaging surface in a central area of the diaphragm where the inlet gas port(s) are located, and at least one surface that does not generally engage the outer portion of the diaphragm, such that a diaphragm floating in the valve chamber engages a central portion of the valve seat surface stopping the passage of gases in or out of the container before a certain pressure is reached, but permitting the passage of gases from within the flexible container as pressure builds, while preventing the flow of atmospheric gases into the container.

  • Patent number: 7631661
    Abstract: Provided is a reversing valve that can reverse flow in a refrigeration system. The reversing valve includes a valve body extending between a first end and an opposing second end. Multiple ports are disposed through the first and second ends. In one aspect, to reduce the pressure drop across the valve body, flow is channeled generally straightly between the ends. This is accomplished by a valve member defining a channel that is coupled to a port at the first end while pivotally movable to intersect different ports at the second end. Flow direction in the system is determined by which port at the second end is intersected. In another aspect, to move the valve member, the reversing valve includes a permanent magnet joined to the valve member and an electromagnet extending partly around the valve body. Applying different polarities to the electromagnet moves the permanent magnet and the valve member.

  • Patent number: 7584803
    Abstract: A sprinkler of the compressed strut and lever type wherein the motion of the lever is limited is disclosed. The sprinkler includes a compression member that compresses a strut against a sealing member that closes the outlet of the sprinkler. One end of a lever is positioned between the compression member and the strut. The opposite end is positioned in proximity to an abutment surface on the sprinkler. The opposite end is engageable with the abutment surface which limits motion of the lever and maintains an offset between the strut and the compression member that renders the strut and lever an unstable mechanism. A frangible link extends between the strut and the lever. The link separates in response to an increase in temperature indicative of a fire condition.

  • Patent number: 7138611
    Abstract: A heating structure and its temperature control method having therein a heat generating line and a controller. The heat generating line includes a PTC element and a short circuit line serially connected having an insulating fusible layer separating them. When a user sets a heating temperature, electric current is conducted to heat the PTC element, alternative string wave signals input into an AC phase shaping circuit and an AC phase delay shaping circuit are converted into square wave signals; and by measuring with a microprocessor at a given time the phase shift between the two phase shaping circuits to control the switch of a trigger circuit, the PTC element can keep on heating or reduce its temperature to therefore keep the heat generating line at a predetermined working temperature. The structure is applicable to heat generating devices such as electric ovens and heating blankets etc.
