  • Metal matrix composites of aluminum, magnesium and titanium using silicon hexaboride, calcium hexaboride, silicon tetraboride, and calcium tetraboride
    Patent number: 7160503
    Abstract: A metal matrix composite was fabricated by adding particles of calcium hexaboride to a metal of aluminum, magnesium or titanium and their alloys. The resulting metal matrix composite is light weight has improved strength, increased elastic modulus and reduced thermal coefficient of expansion, thus making the metal matrix composite more useful in industry. A metal matrix composite is also formed by mixing particles of aluminum, magnesium, titanium or combinations thereof with particles of silicon lexaboride, calcium hexaboride, silicon tetraboride, calcium tetraboride or combinations thereof. The blended particles are processed according to powder metallurgical techniques to produce a metal matrix composite material.

  • Vent for reducing seal pressure in pump assembly
    Patent number: 7137789
    Abstract: An engine pump is provided which operates with an internal combustion engine or as a supplemental pump or as used in a stand alone device, and includes an internal vent for improved pump and motor durability. The pump is operably and sealably connected to a motor and adapted for connection with a source of fluid and a discharge means. An internal vent is positioned in between an armature shaft of bore along an inlet port thereby decreasing the pressure in the area of the seal. Alternatively, a valve is positioned between the inlet and outlet ports to selectively permit fluid pumped between the inlet and outlet ports to pass through when the outlet port is flow restricted.

  • Process for the production of bisphenol-A
    Patent number: 6933416
    Abstract: The invention provides a process for the continuous production of bisphenol-A by continuously reacting phenol using an acid catalyst resin and continuously or essentially continuously removing water from the system. Continuous removal of water allows for increased catalytic activity of the resin and therefore improved productivity. Removal is facilitated by conducting the process in a carousel simulated moving bed device. Process efficiency is further enhanced by conducting the process in a device configured to have a combination of series, parallel or reverse flows which are optionally arranged so the process results in higher yield and lower impurities.
