Static Dropless Flake Aligner For Producing Composite Wood Material, Gordan P. Krueger, Anders E. Lund, Roy D. Adams
Static Dropless Flake Aligner For Producing Composite Wood Material, Gordan P. Krueger, Anders E. Lund, Roy D. Adams
Michigan Tech Patents
Apparatus are provided for forming a loosely felted mat of elongated wood flakes, the wood flakes being supported on an elongated caul. The flakes are deposited between a plurality of closely spaced parallel baffles so as to be aligned in mutually parallel relation. The caul is supported adjacent the lower edges of the baffles and is support for vertical movement to facilitate buildup of the mat. Apparatus movable back and forth along the length of the caul is provided to deposit wood flakes in an evenly dispursed manner. At least one picker wheel also moves along the length of the …
Apparatus For Making Continuous Lengths Of Composite Wood Material, The Apparatus Including Rotating Circular Baffles, Anders E. Lund, Gordon P. Krueger, Bruce A. Haataja, Roy D. Adams
Apparatus For Making Continuous Lengths Of Composite Wood Material, The Apparatus Including Rotating Circular Baffles, Anders E. Lund, Gordon P. Krueger, Bruce A. Haataja, Roy D. Adams
Michigan Tech Patents
Apparatus for forming an elongated loosely felted mat of thin elongated wood flakes with the flakes being aligned in mutually parallel relation and being aligned with the longitudinal direction of the elongated mat. The apparatus comprises a plurality of conveyor belts positioned in closely adjacent side-by-side relation and defining a mat supporting surface adapted to support the aligned wood flakes, the belts being supported on the surface of a cylinder. Wood flakes are deposited in loosely felted relation on the belts, and a plurality of closely spaced parallel planar baffles surround the cylinder, the baffles comprising plates positioned between the …
Multiple Funnel Flake Aligner For Making A Loosely Felted Mat Of Aligned Wood Flakes, Bruce A. Haataja, Tauno B. Kilpela, Gordon P. Krueger, Roy D. Adams
Multiple Funnel Flake Aligner For Making A Loosely Felted Mat Of Aligned Wood Flakes, Bruce A. Haataja, Tauno B. Kilpela, Gordon P. Krueger, Roy D. Adams
Michigan Tech Patents
Apparatus for forming a loosely felted mat of thin elongated wood flakes with said flakes being aligned in mutually parallel relation. The apparatus includes a mat supporting surface, a hopper for holding a quantity of wood flakes, and a funnel assembly for receiving wood flakes from the hopper and for causing the flakes to be aligned in substantially parallel side-by-side relation as they are deposited on the supporting surface. The funnel assembly includes a plurality of funnels positioned in adjacent side-by-side relation, the funnels each including inclined walls having lower edges defining an elongated narrow opening adjacent the supporting surface …
Method For Reducing Macrosegregation In Alloys, Angus Hellawell
Method For Reducing Macrosegregation In Alloys, Angus Hellawell
Michigan Tech Patents
Macrosegregation in metal alloy castings and other alloys having similar solidification behavior is reduced by slowly rotating a mold or the like containing the liquid alloy about an axis at an acute angle to the vertical from the time the liquid alloy is poured into the mold until substantially all of the alloy has solidified. The mold is rotated at a speed below that which produces a centrifuging effect or causes stirring or agitation of the interdendritic liquid.
Method For Preparing Organic Hyponitrites, G. David Mendenhall
Method For Preparing Organic Hyponitrites, G. David Mendenhall
Michigan Tech Patents
Tertiary organic hyponitrite usable as initiators for polymerizing ethylenically unsaturated compounds are prepared by reacting an alkali metal, alkaline earth, ammonium or substituted ammonium salt of hyponitrite, such as sodium hyponitrite, with a tertiary organic halide, such as tert-butyl chloride, in the presence of one or more weak Friedel-Crafts catalysts, such as ferric or zinc chloride, and in a solution of a neutral solvent.
Method For Molding Articles Having Non-Planar Portions From Matted Wood Flakes, Bruce A. Haataja, Tauno B. Kilpela, Anders E. Lund, James F. Hamilton
Method For Molding Articles Having Non-Planar Portions From Matted Wood Flakes, Bruce A. Haataja, Tauno B. Kilpela, Anders E. Lund, James F. Hamilton
Michigan Tech Patents
An article having non-planar portions, such as a pallet having a substantially flat deck member and a plurality of hollow leg members projecting integrally from the deck member, is molded as a one-piece unit from a loosely-felted, layered mat formed from a mixture of a resinous particle board binder and flake-like wood particles. The wood flakes have an average length of about 11/4 to about 6 inches, preferably about 2 to about 3 inches, an average thickness of about 0.005 to about 0.075 inch, preferably about 0.015 to about 0.025 inch, and an average width of 3 inches or less …
Flake Aligner Including Baffles Supported On Continuously Moving Conveyor, Anders E. Lund, Gordon P. Krueger, Lynn B. Sandberg, Roy D. Adams
Flake Aligner Including Baffles Supported On Continuously Moving Conveyor, Anders E. Lund, Gordon P. Krueger, Lynn B. Sandberg, Roy D. Adams
Michigan Tech Patents
Apparatus for forming a continuous elongated loosely felted mat of thin elongated wood flakes with the flakes being aligned in mutually parallel interleaved relation. The apparatus includes a plurality of belts positioned in adjacent side-by-side relation and for continuous movement so as to define a supporting surface for the mat. A plurality of sets of thin planar baffle plates are provided, each set including a plurality of thin planar baffle plates supported in coplanar alignment and in edge-to-edge adjacent relation. The baffle plates are positioned between a hopper for depositing wood flakes and the supporting surface and function to align …
