  • Patent number: 4666725
    Abstract: Blood is supplied continuously from a blood collecting vessel to a stirrer through a pump located at the bottom of the vessel. Vapor in the form of heated live steam is sprayed against the blood in the stirrer to coagulate a protein in the serum.

  • Patent number: 4653527
    Abstract: A pressure relief valve is disclosed. The pressure relief valve comprises a valve housing including fluid passageways, a poppet valve disposed within the housing, a piston disposed within the housing, and spring means disposed intermediate the piston and the poppet valve for biasly urging apart the piston and the poppet valve. The poppet valve has a valve seat which, together with a portion of the housing, defines a variable valve area. The piston has a piston area, relatively greater than the variable valve area, for modulating flow through, and pressure drop across, the poppet valve. The pressure relief valve preferably includes an orifice disposed within the housing for selectively controlling flow of hydraulic fluid through the housing passageways to the piston. The housing preferably includes an elongated cage within which the poppet valve is longitudinally slidable.
