Title: Emergency pressure relief valve with enhanced reset
Inventor: MATZNER MARK D
IPC: F16K17/02
Filed: 2004-10-21
Abstract: A pressure relief valve has a housing fluidly connected to a pressurized system line carrying a system fluid. The housing carries a moveable piston and a valve member that both move between closed and open positions. The piston defines an upper chamber and a lower chamber within the housing. A pressurized fluid is supplied to the upper chamber to bias the piston toward the closed position.  After the relief valve opens from excessive system pressure, the pressurized fluid is injected into the lower chamber to delay the return of the piston to the closed position. Initially, the fluid in the lower chamber flows through a check valve while the piston returns to the closed position. Then the fluid went in the lower chamber vents from the lower chamber as the piston and valve member approach the closed position.

Abstract: The present invention relates to a process for the manufacture of structural recyclable thermoplastic composites where lignocellulosic fibres are well dispersed in a thermoplastic matrix while maintaining an average fibre length not below 0.2 mm. The process consists of defibrillation the lignocellulosic fibres in the presence of surface active agents using a high shear mixer and at a temperature less than the melting point of surface active agent to individualize and separate the fibres, decrease fibre diameter and form microfibrils, followed by dispersion of the cellulosic fibres in the thermoplastic matrix by intensive mechanical mixing to get the moldable thermoplastic composition, followed by injection or compression or compression injection molding of said composition. The process produces high performance composite materials having a tensile strength not less than 55 MPa, a flexural strength not less than 80 MPa, a stiffness not less than 2 GPa, notched impact strength not less than 20 J/m, and un-notched impact strength not less than 100 J/m.
