  • Patent number: 11963582
    Abstract: Golf shoes having improved constructions are provided. The golf shoes include upper, midsole, and outsole sections. The upper may be made of a soft, breathable leather material. The midsole includes an upper region formed from a first material such as a foamed ethylene vinyl acetate (EVA); and a lower region formed from a second material such as a foamed ethylene vinyl acetate (EVA), wherein the materials have different hardness levels. A fiber-reinforced composite plate such as, for example, a carbon fiber plate is disposed in the midsole. The composite plate has a molded three-dimensional shape to provide additional stiffness to the golf shoe, particularly in the rear foot region of the shoe. The outsole contains different traction members arranged in a precise geometric structure that helps provide improved stability and traction.

  • Publication number: 20240123449
    Abstract: A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container.

  • Patent number: 4795033
    Abstract: A container for edible materials such as fruits and vegetables is fashioned in two parts from low density polyethylene material. A joint is provided between the two parts which allows the parts to be separated while the contents are inserted or used, and to then be reclosed. The joint may be a simple frictional connection, but the joint may also include and interference type of connection. The two parts define an internal cavity which is sized to accommodate individual pieces of fruit or vegetable such as citrus fruit like lemons and limes, yellow onions, tomatoes, leafy vegetables like lettuce an cabbage, squash, cucumbers, carrots, green onions, and celery.
