  • Patent number: 4893576
    Abstract: A fender for marine use having an outer flexible elastomeric shell and containing therein a solid foam bun, and its method of construction is described. The method includes forming the shell in two halves, inserting the solid foam bun into the two halves, and thereafter molding the two halves into an integral unit. The marine fender has excellent flexibility and structural integrity.
    Type: Grant

  • Patent number: 4360498
    Abstract: The present invention relates to an end box for chemical cells, such as cells for producing chlorine. Such end boxes are known and are lined with a corrosion-resistant lining. The end box of the present invention is formed in a plurality of sections and is provided with separating baffles. These sections and baffles are individually and completely covered with a corrosion-resistant lining which is soft and flexible, and which can doubly function as a gasket material so that when the end box sections are assembled, no gaskets are required and the individual sections and baffles can be separately removed for replacement without disassembling the entire end box or removing the complete assembly from an associated cell.

  • Patent number: 4136632
    Abstract: A fender for marine use is described having an outer flexible shell forming a chamber, compressible buoyant material within the chamber and a mooring fitting connected to the shell to secure the fender. The shell is composed of a single piece of homogeneous elastomeric material, having a thickened annularly shaped lip extending around an orifice providing access to the chamber for filling. The mooring fitting is formed with a cavity and the lip of the shell is captured within this cavity to secure the fitting to the shell, so that the shell permits stretching of the fender when it is pinned between two objects while a tensile force is applied to said mooring fitting. The mooring fitting captures the lip without compressing it, so that the fitting may swivel with respect to the shell while still securing the shell from separating from said fitting.
