  • Publication number: 20170203361
    Abstract: The teachings provide a fill tube assembly for a casting mold and methods of using the assembly. The fill tube assembly includes a fill tube having a tubular member with a receiving end, a mold-engaging end and an intermediate portion. The mold-engaging end has a tapered flange radially extending therefrom, the remainder of the tubular member has a substantially, uniform cross-section. A clamping assembly is structured to maintain a substantially leakproof seal at the fill tube, casting mold interface while accommodating dimensional variations. The clamping assembly includes a gasket, a load ring, a clamping plate and a pre-load gap between the clamping plate and the casting mold and optionally includes a dimensional compensating ring. When tightened, the clamping plate biases the load ring against the flange thereby distributing a uniform load against the casting mold, compressing the gasket therebetween while narrowing the pre-load gap to accommodate dimensional variations.

  • Publication number: 20100089873
    Abstract: A method of producing a metal structure with a grooved wicking surface is provided. An aluminum alloy is provided that is thermomechanically processed to produce grain size and shape suitable for wicking. Then, the alloy is heat treated to produce a continuous etchable phase on the grain boundaries. The alloy is then etched with a solvent that dissolves the continuous etchable phase on the grain boundaries to produce the metal structure with a grooved wicking surface. In addition, the method of producing a laminate metal structure with a grooved wicking surface is provided. The laminate is provided with at least a top layer and a bottom layer where the top layer and bottom layer are made of an aluminum alloy. The laminate is thermomechanically processed to produce grain size and shape spanning the entire depth of the top layer suitable for wicking. Then, the laminate is heat treated to produce a continuous etchable phase on the grain boundaries within the top layer.

  • Patent number: 6056349
    Abstract: A vehicle door has a door body which includes an outer door panel, an inner door panel, and a recess disposed therebetween. A metal mat has a plurality of elongated first elements and a plurality of second elements interwoven with respect to the first elements. The metal mat is secured directly or indirectly to the door body. The first elements are movable with respect to the second elements such that the application of an impact force thereto will result in relative sliding movement caused either by displacement of the first elements or second elements, or stretching of the same under the influence of the impact force, or both. In a preferred embodiment, peripheral portions of the woven mat are fixedly secured to a frame which is in turn secured to the door body. The first elements are preferably offset from the second elements about 50 to 100 degrees. In one embodiment a plurality of third elements oriented generally in the same direction as the second elements are interwoven with the first elements.

  • Patent number: 4155244
    Abstract: A method and apparatus for measuring thermal conductivity of materials is provided. A test specimen is placed intermediate a hot plate and a cold plate, and a heat flow sensing means is placed intermediate the material to form two portions of the test specimen. A guarded hot plate measurement of the heat flow to the hot plate enables calibration of the sensitivity of the specimens and the heat flow sensing means. The apparatus is then calibrated for measurement of other specimens of like physical properties.
