    摘要: One method of the present invention includes introducing a slurry into a mold unit comprised of a mold contained within a casting receptacle and lowering the temperature of the slurry to freeze the slurry and form a freeze-cast substrate while controlling temperature gradients within the mold unit to minimize distortion in the freeze-cast substrate. Another method includes introducing a slurry into a mold unit comprised of a mold contained within a casting receptacle, placing insulation material around at least a portion of the casting receptacle to minimize distortion in the freeze-cast substrate by controlling temperature gradients within the mold unit, and lowering the temperature of the slurry to freeze the slurry to form a freeze-cast substrate.

    摘要: Method and arrangement for spray forming an article. The method includes spraying a plurality of metal streams upon a low-heat resistant model and thereby forming a spray formed article. Each of the plurality of metal streams is composed of moltenized droplets, and as between the plurality of metal streams, each is composed of different constituent elements. In the spray form process, conditions of the metal streams are controlled, particularly around the time that the droplets land, to prevent adverse affects such as melting or burning the master model. The spray conditions are controlled in such a manner that the individual metal droplets forming the metal streams remain substantially segregate. The segregated state is maintained through out solidification so that the resulting spray formed article is composed at least partially of psuedo-alloy.

    摘要: A method to attach a V-shaped or parabolic-shaped blast shield or other blast shields, to the bottom of a vehicle space frame that serves the purpose of redirecting the blast forces away from the crew compartment of the vehicle. Inner beams that run the length or width of the blast shield, align with the space frame running in the same direction. The beams are attached with bolts going through the top of each beam and into a threaded boss welded in the space frame. To attach the sides of the blast shield to the space frame, a rail adapter bracket mounts to the bottom of the space frame that has threaded bosses welded into the space frame. Slotted holes for forward and back and side-to-side adjustment on an adapter bracket are employed to help attach the blast shield to the space frame.

    摘要: A method of attaching a metal shaft (10) to a ceramic shaft (12) having a first diameter (d.sub.1) is characterized by the following steps. A shaft portion (16) is formed on the ceramic shaft with a second diameter (d.sub.2) less than the first diameter. The shaft portion extends from a free end (18) thereof along a portion of the length of the ceramic shaft to a terminal end (20) thereof where the ceramic shaft has a raised portion (22) formed thereon having a third diameter (d.sub.3) less than the first diameter but greater than the second diameter. The free end of the shaft portion has threads (24) thereon. A circular shaped expansion sleeve (26) is placed on the shaft portion in an encircling relationship therewith, the expansion sleeve extending from the raised portion of the metal shaft to a location (28) adjacent a termination of the threads on the shaft portion. All of the members are cooled and then assembled with the metal shaft. The metal shaft is formed so as to have both a hollow interior portion (30) having a diameter slightly greater than the third diameter of the raised portion of the ceramic shaft and an internally threaded hollow portion (32). The assembly is carried out so that the threads of the ceramic shaft are mated with the threads of the metal shaft. The expansion sleeve is trapped in a volume defined by the shaft portion of the ceramic shaft, the hollow interior portion of the metal shaft, the raised portion of the ceramic shaft, and a closed end (34) of the hollow interior portion of the metal shaft.

    摘要: The adjustable louvered armor window system invention comprises angled louvers made of the lightweight opaque armor. For the front window a viewing window of ballistic glass can be installed, the rear or sides could be solid armor. The louvers have overlaps to provide for gap protection. When no threat is present, the louvers are in the full open position. Once a threat is detected, then the louvers are closed. The movement of the louvers can be accomplished by a push/pull cable, hydraulic pressure, air pressure or other means. The system in the fully open position allows for a complete unobstructed viewing area. In the semi-deployed or partial down position, the system provides partial ballistic coverage for the occupant, and still allows for some occupant vision capability. In the fully deployed, or fully closed position, the system provides full ballistic coverage for the occupant, with a small viewing area or port, which is made of ballistic grade transparent armor.
