  • Thermal sensing apparatus in outlet nozzle
    Patent number: 4822570
    Abstract: A valve supports a thermal sensing apparatus within an outlet nozzle of a reaction vessel. The valve includes a head with a socket closed by a disc and a stem providing a bore communicating with the socket and a measuring end defined by the disc. The sensing element of the sensing apparatus is located to a sensing position at the measuring end of the valve for fast response to a thermal change in the contents within the vessel. Substantially any form of sensing element may be incorporated in the valve and the sensing element is spring biased toward the measuring end.
