  • Patent number: 6854926
    Abstract: A zero ground disturbance dike apparatus and method for the secondary containment of harmful chemicals that are stored in primary storage vessels, wherein the dike apparatus does not require the drilling of postholes or the setting of support posts in concrete. Sections of dike walls are attached to bracing assemblies, each bracing assembly being comprised of a brace and a base plate. Braces are configured to support the assembled wall sections and to provide resistance against the outwardly force exerted by material that is released from the primary storage vessel. Base plates attached to the braces assist in resisting bending moments that may be created about the base of the dike apparatus. The brace assembly also preferably includes at least one base support channel for additional base plate stiffness and support cables to further resist the outwardly forces exerted against the dike apparatus by said released materials.

  • Patent number: 5158415
    Abstract: A suspension system for brake calipers wherein two brake rods pass through two plates so that the brake rods are aligned parallel to each other. The barke rods are longer than the distance between the two plates so that the ends of the brake rods extend away from the two plates far enough to hold brake calipers in place about the brake discs. Each brake rod further includes compression springs mounted thereon and located between the plates so that when the appropriate spring are compressed, the corresponding ends of the brake rods can be withdrawn from their position holding the caliper. This allows easy and convenient access to the calipers for removal.
