  • Patent number: 8061698
    Abstract: A geometric shaped side bearing pad includes a top and a surface extending an angle ? towards the top, wherein the bearing pad has a geometric shape and a non-linear spring rate which levels out a reaction force without buckling. The surface of the bearing pad can have two sides or four sides, can have spacing within the surface, or can be solid. The angle ? can be within the range of about 20 degrees and 85 degrees, and may preferably be within the range of about 30 degrees and 45 degrees to achieve non-linear load/deflection. The top of the bearing pad can have a slot defined therethrough to accommodate a protrusion in a fixture to engage the bearing pad. The bearing pad can provide a friction contact with an object and enables lateral force transfer to the bearing pad, thereby providing lateral stiffness.

  • Patent number: 7909192
    Abstract: The invention is a vent for use with a container, such as commercial steel pails and drums, and a method for venting containers. The vent has a cap seal with one or more semipermeable membranes covering an orifice in the cap seal. The membrane prevents the passage of at least one atmospheric component, but allows the free passage of air. When a product is filled into the container at an elevated temperature and cools, a vacuum is formed within the container. The resulting vacuum opens a vacuum release device in the vent and pulls air through a hole in the cap seal, which is protected by a micro-porous membrane. The venting of air into the container relieves the vacuum without damage to the container or the product within the container.
