The method includes advancing a beam spot of a laser beam relative to a top surface of the workpiece stack-up and along a beam travel pattern to form a laser weld joint, which is comprised of re-solidified composite metal workpiece material, that fusion welds the metal workpieces together. And, while the beam spot is being advanced along the beam travel pattern, between a first point and a second point, which may or may not encompass the entire beam travel pattern, at least one of the following laser beam parameters is repeatedly varied: (1) the power level of the laser beam; (2) the travel speed of the laser beam; or (3) the focal position of the laser beam relative to the top surface of the workpiece stack-up.
US10195504 — BASEBALL OR SOFTBALL BAT WITH MODIFIED RESTITUTION CHARACTERISTICS — Mizuno Corporation (Japan) — A softball or baseball bat with modified restitution characteristic is provided. The bat can comprise a substantially rigid core or shell made of an aluminum alloy coupled with a single or multi-piece sleeve. The core can comprise a tip end, a barrel taper, a handle taper, and a handle. The sleeve can slide over the handle portion and can be pressed, molded, or adhered to the barrel taper. The resilient sleeve can be sized and shaped such that the sleeve portion is substantially the same diameter as the tip end. The sleeve can comprise a material capable of impact absorption. The sleeve can have a composite structure with inner and outer sleeve components. The sleeve can further comprise a cone to taper the sleeve in the handle taper portion of the bat. The material and thickness of the sleeve and the core can be varied to meet applicable restitution requirements.
US10190200 — ALUMINUM-COPPER-LITHIUM PRODUCTS — Constellium Issoire (France) — The present invention relates to extruded, rolled and/or forged products. Also provided are methods of making such products based on aluminum alloy wherein a liquid metal bath is prepared comprising 2.0 to 3.5% by weight of Cu, 1.4 to 1.8% by weight of Li, 0.1 to 0.5% by weight of Ag, 0.1 to 1.0% by weight of Mg, 0.05 to 0.18% by weight of Zr, 0.2 to 0.6% by weight of Mn and at least one element selected from Cr, Sc, Hf and Ti, the quantity of said element selected, being 0.05 to 0.3% by weight for Cr and for Sc, 0.05 to 0.5% by weight for Hf and 0.01 to 0.15% by weight for Ti, the remainder being aluminum and inevitable impurities. he method according to the present invention makes it possible to manufacture an extruded, rolled and/or forged product. The products and methods of the present invention offer an advantageous compromise between static mechanical strength and damage tolerance and are useful in aeronautical design.
US10189340 — FOLDING TONNEAU COVER APPARATUS — Agri-Cover, Inc. (USA) — A folding tonneau cover apparatus including a cover assembly and a support frame assembly. The cover assembly having a plurality of rigid panels interconnected in series by a series of flexible hinges preferably made from a laminated woven fabric material. The rigid panels are preferably stiffened by elongated support members secured to the undersides of the respective panels and the top surfaces of portions of the rigid panels are preferably downwardly concave. The cover assembly is secured to the support frame assembly to cover a cargo box of a pickup truck by a plurality of locking members when the support frame assembly is secured to sidewalls of the cargo box. Methods of making a tonneau cover apparatus and methods of folding and unfolding the cover assembly are also disclosed.
