    摘要: An energy absorbing beam structure has controlled crush characteristics. The beam is an elongated structure in which at least a portion of the length of the beam is configured so that a cross section taken transverse to the length of the beam defines a first sidewall, a second sidewall, a first hollow flange projecting from the first sidewall and a second hollow flange projecting from the second sidewall together with a front wall extending between the first and second sidewalls. The beam may be configured to define an open or closed tubular structure and may define one or more central lobes. In an impact condition the beam crushes in a reliable and controlled manner so as to absorb a large amount of kinetic energy. Further disclosed are motor vehicles which include the energy absorbing beams as well as roll forming processes for fabricating the beams.

    摘要: The present invention relates to a method of spray forming a boron steel metal article, and to the formed article. In at least one embodiment, the method comprises (a) providing a spray forming pattern, (b) spraying metallic particles onto the spray forming pattern, and (c) allowing the sprayed metallic particles to cool to form a metal article. In at least one embodiment, the metallic particles are sprayed from a carbon steel feedstock having a boron content of 0.25-2.25 weight percent, based on the total weight of the feedstock.

    摘要: A propeller comprises a first elongate, non-twisted part (1) of streamlined cross-section and of constant cross-sectional area and constant shape from one end of said part to its other, and a second, planar part (2) which connects with one longitudinally extending edge of the first part and which is of constant thickness and breadth. The second part (2) has a surface (5) which merges at least substantially tangentially with one, convex single-curve surface (3) of the first part, and a surface 6 which merges smoothly with the other surface (4) of the first part (1).
