  • Multicell recombining lead-acid battery
    Patent number: 4383011
    Abstract: A recombining lead-acid battery with absorbed electrolyte is disclosed having multiple cells positioned in a sealed monobloc container, and cell partitioning members constructed to define a gas space common to all the cells of the battery.

  • Method of forming hose with improved resistance to deformation
    Patent number: 4361455
    Abstract: A hose resistant to deformation is described which includes the usual polymeric tube and outer cover, and at least one annular reinforcement layer of fiber bundles sandwiched between the tube and cover. A polymeric aqueous-insoluble continuous film impregnates the fiber bundles and binds the reinforcement to at least one of the cover and tube, the continuous polymeric film serving to unexpectedly stiffen the hose appreciably. A method for producing the hose is described wherein the adhesive film is formed by applying a latex dispersion to the hose tube and/or reinforcement.
