  • Nonwoven web and film laminate with improved strength and method of making the same
    Patent number: 6649548
    Abstract: There is disclosed a nonwoven web/film laminate for use as a fabric in personal care products. The laminate is formed of at least two layers in an SF formation. The spunbond (S) layer of the laminate is formed of preferably metallocene catalyzed polypropylene. The film (F) layer is formed of a polyolefin which may be metallocene-catalyzed.

  • Apparatus for making electrode material from high hardness active materials
    Patent number: 4765598
    Abstract: A method and apparatus for making electrode material from high hardness active electrode alloy powder are disclosed. In one embodiment, the method involves feeding the powder onto a carrier web, aligning a mesh or screen substrate with the carrier web, and compacting the powder and mesh in a series of roller mills. The carrier is removed after it has passed through the first roller mill, and the remaining green electrode web is passed through the second roller mill and into a sintering furnace. After sintering and cooling, the web is calendared, and then is wound on a take-up reel. The furnace provides a substantially water and oxygen-free argon-hydrogen atmosphere for sintering which discourages web oxidization at the elevated sintering temperature. A loss-in-weight feeder can be used to accurately deposit the desired amount of active material on the carrier web.

  • Activated rechargeable hydrogen storage electrode and method
    Patent number: 4716088
    Abstract: Activated rechargeable hydrogen storage electrodes that are especially suitable for sealed, starved electrochemical cells and methods for making them are provided. The activated electrode includes a body of hydrogen storage active material that is composed of an agglomeration of particles of active hydrogen storage material. The body contains a residual amount of hydrogen and may have a modified surface, the residual amount of hydrogen generally being equivalent to a potential of about -0.7 volts versus a Hg/HgO reference electrode when discharged at a rate of about 5 mA/gram to 25 mA/gram of active material.
