  • Check valve
    Patent number: 11320059
    Abstract: A check valve for a pump delivery port includes a body having inlet and outlet portions joined by a duct and an opening; a curve having an inlet end to be connected to the delivery port and an outlet end to be connected to the body; and a valve member having a disk-shaped locking portion sealingly interacting with an edge of the curve and a locking portion secured in a seat by a lid of the opening. The valve member moves between open and closed positions and has a metal core made while the locking portion is metal-free. The lid cooperates with the locking portion through a protrusion or a cavity and pushes the valve member toward the curve to the closed position and allows the valve member to deflect to the open position under pressure of a working fluid in equilibrium with the weight of the blocking portion.
    Type: Grant

  • Chemical compositions based on titanium trihalides, method for their preparation and their uses
    Patent number: 4217245
    Abstract: A novel catalyst system for the polymerization or copolymerization of olefines, more particularly to ethylene is disclosed. For preparing the novel catalyst system, a titanium compound (Ti IV) is previously attached to a solid supporting member, whereafter the so anchored Ti is reacted with vapors of a metal, in the presence of a halogenated compound or not. Very high polymer yields are obtained and examples are given.
