  • Patent number: 11253898
    Abstract: A hot-forming press (100) comprises a lower press assembly (102) and an upper press assembly (108). The lower press assembly (102) is movable along a vertical axis and comprises a lower die (106), and a lower hot-box portion (104), configured to receive the lower die (106). The upper press assembly (108) is movable along the vertical axis above the lower press assembly (102) and comprises an upper die (112), and an upper hot-box portion (110). The upper hot-box portion (110) is configured to receive the upper die (112) so that the upper die (112) is positioned opposite the lower die (106). The lower die (106) and the upper die (112) are configured to apply a forming pressure to a workpiece (114) that is received between the lower die (106) and the upper die (112). The lower hot-box portion (104) and the upper hot-box portion (110) are configured to heat the workpiece (114).

  • Patent number: 11136800
    Abstract: A roller facilitates movement of a gate or similar barrier between a first and second position. The barrier fits at least generally within a channel formed at the periphery of the roller, and the channel is shaped to reduce the contact area and resulting friction that can otherwise occur between the confronting surfaces of the channel and the barrier.

  • Publication number: 20210010290
    Abstract: Methods and apparatus are disclosed for an improved barriers and fence systems, including a supplemental panel for fences or gates or the like, alone and or in combination with such pre-existing fences/gates or similar elements. The supplemental panel can be fabricated using relatively cost-effective materials and processes, and effectively reduces the space or gaps between generally vertical pickets and/or horizontal elements on an existing fence/gate/etc., and is readily mounted and racked into generally parallel alignment with those existing generally vertical pickets, and the mounting can be independent of the racking function/structure (such as by bending the added vertical picket elements at a selected/provided location on each added picket). The added vertical elements can be low-visibility and selectively spaced laterally to fit aesthetically between the existing pickets.

  • Patent number: 9517890
    Abstract: An apparatus for singulating logs comprises a stationary support at least one inclined stationary surface and a top edge and a first reciprocating support having a top step positioned against the inclined stationary surface. The first reciprocating support is movable between a bottommost position wherein the top step is positioned below the top edge of the stationary support and a topmost position wherein the top step is positioned above the top edge of the stationary support. The apparatus further comprises a plurality of fingers extending from the top step wherein each of the fingers has a length adapted to regain a log on the top step at a topmost position of the first reciprocating support and to retract into the stationary support at the bottommost position of the first reciprocating support.
