  • Patent number: 8056427
    Abstract: An adjustable head tool (AHT) is configured for positioning a free motion headform (FMH) having a regulated FMH backoff requirement prior to an impact between the FMH and a target surface having a target point. The AHT has a built-in or a variable backoff angle relative to the position of the target point, and includes a cranial portion and an adjustable facial template. The cranial portion encloses a linkage assembly, and the facial template has one or more facial features. A rotary dial translates the facial template with respect to the cranial portion to maintain the regulated FMH backoff requirement. The cranial portion includes a forehead impact zone having a first set of demarcations, and the rotary dial has a second set of demarcations corresponding to the first set of demarcations. The dial is set so the second set of demarcations matches the first set during positioning of the AHT.

  • Patent number: 6869132
    Abstract: A beam system of telescoping tubes is used for absorbing side impacts to a passenger vehicle. A central outer tube is attached to a vehicle seat structure and extends between, e.g., a side door and the tunnel in the passenger compartment floor. Inner tubes in each end of the outer tube are moved between retracted positions to extended positions respectively engaging said tunnel and said door during vehicle operation. Each inner tube has a tapered piston carrying rolling elements for wedging against the outer tube for energy absorption upon a side impact.

  • Patent number: 5009747
    Abstract: A method for hydroentangling nonwoven fibrous sheet material to significantly increase the strength thereof at low latex add-on values employs small diameter jets of high-pressure water in the form of coherent streams that concentrate the hydraulic energy over a distance equal to approximately the diameter of the fibers being entangled. While fiber entangling water jets have been utilized heretofore, the present invention employs a relatively lower pressure for the fiber rearrangement along with a synergistic effect of wood pulp and long polyester fibers coupled with small amounts of latex to achieve the unexpectedly high strengths within these light weight materials. The resultant sheet material possesses excellent uniformity of fiber distribution and improved strength characteristics over those typically obtained from prior art water jet enganglement processes requiring 300-2000% the enganglement input energy employed in this process.

  • Patent number: 4174226
    Abstract: The invention relates to an alumina based, phosphate bondable, dry refractory mix composition exhibiting an extended shelf life of up to eighteen months and longer. The mixture has the following preferred composition on a weight percentage basis: 40-70% sized tabular alumina, 15-35% calcined alumina, 2-10% hydrated alumina, 1-10% calcium aluminate cement and an acid ingredient such as 3 to 15 weight percent of an 115 percent concentration of polyphosphoric acid. The mix is prepared by a method which comprises the steps of formulating dry ingredients into a mixer, mixing the dry ingredients to a homogenous state, then adding a liquid acid ingredient to the mixture of dry ingredients, and subjecting the dry and acid ingredient mix to a high intensity mixing action for a predetermined period of time. The product is substantially dry to the touch.
