Abstract: The invention relates to a susceptor lid for use in a CVI/CVD furnace. More specifically, the invention is directed to a lid configured to consecutively run CVI/CVD and heat treatment processes without opening the furnace. The susceptor lid according to the invention comprises: a susceptor lid body having a gas exhaust hole, the susceptor lid body having a top surface and a bottom surface; and an exhaust lid disposed over the gas exhaust hole, with a clearance between the exhaust lid and the gas exhaust hole such that exhaust gas pressure within the clearance is approximately equal to, or less than the exhaust gas pressure within the gas exhaust hole, the exhaust lid being positioned to block the majority of the radiation from below the bottom surface of the susceptor lid body.

Abstract: The invention relates to the field of damping in load-carrying members, particularly those load-carrying members that carry a load between a plurality of masses that are subject to induced cyclic distortion or vibration. According to an aspect of the invention, a damped structural member is provided that carries a load between a first mass and a second mass. The damped structural member comprises a load-carrying member that carries the load between the first and second masses, and at least one damping member nested with the load-carrying member. The damping member and the load-carrying member move relative to each other during cyclic distortion of the load-carrying member thereby dissipating distortion energy at a damping interface between the damping member and the load-carrying member. The damping member bears essentially only cyclic loads induced by cyclic bending mode movement of load-carrying member. A method for damping a structural member is also provided.

Abstract: A novel energy hydraulic media is disclosed comprising a microgel dispersion. The microgel dispersion is a Non-Newtonian fluid.

Examples include hydraulic brake systems, liquid springs, and dynamic damping devices such as aircraft landing gear shock struts, car bumpers, and automobile shock absorbers. Methods of transmitting hydraulic energy and for dissipating kinetic energy using this microgel dispersion are also disclosed.

Abstract: The present invention relates to zeolites and the process for forming such zeolites.

Abstract: The invention is relates to CVI/CVD furnace apparatus. More specifically, the invention is directed to a sealed gas inlet for a high temperature CVI/CVD furnace. A method and apparatus are provided for preventing gas leakage around a gas inlet extending through a hole in a susceptor floor in a CVI/CVD furnace. According to the invention, the gas inlet is sealed to the susceptor floor with sufficient intimacy to block leakage of gas through the hole around the gas inlet while allowing the gas inlet to cyclically translate through the hole due to thermal expansion and contraction induced by thermal cycles in the CVI/CVD furnace.

Abstract: Thermoplastic molding compositions and articles comprise immiscible thermoplastic polymer components and reinforcing fibers. The immiscible thermoplastic polymer components and the fibers are blended together under high shear conditions. The molding composition generally contains at least two phases and has an extremely smooth and fiber-free surface. Generally, other very good physical properties are obtained such as high heat distortion temperatures, high tensile modulus, high flex modulus, and the like are also very good. A desired blend of thermoplastic components is thermoplastic polyurethane and modified polyethylene terephthalate with glass fibers. The molded polyethylene terephthalate copolyester blended with an immiscible thermoplastic polymer, preferably modified polyurethane, and glass fibers produces thermoplastic molding compositions and articles having surprisingly superior impact strength.
