Abstract: There is disclosed a filled cellulosic fiber composition, as well as a method for filling dried cellulosic fibers with an inorganic filler by contacting the dried fibers with a first salt solution, followed by contact with a second salt solution. The first and second salt solutions combine to form a precipitate within the cell wall of the cellulosic fibers. The filled cellulosic fiber composition may be made into a variety of paper products, including paper, having a high filler content. The precipitates of the present invention include carbonates, phosphates, silicates and borates of aluminum, barium, calcium, magnesium and zinc. The first salts include carbonates, phosphates, silicates and borates of sodium, ammonium, potassium and lithium, and the second salts include chlorides, nitrates, and sulfates of aluminum, barium, calcium, magnesium and zinc.

Abstract: Apparatus for transferring powdered ore from a storage tank to a bin associated with an electrolytic cell. The cell defines a chamber containing an electrolyte and includes means for transferring ore from the bin to the chamber. The apparatus comprises a fluidizing conveyor for conveying powdered ore from a storage tank to the bin, a first vent interconnecting the conveyor and bin and a second vent interconnecting the bin and chamber. In a preferred embodiment, a source of pressurized gas causes ore to flow through the conveyor, and the apparatus further comprises a pressure switch for closing the source in response to a buildup of fluid pressure in the conveyor. Another preferred feature is a fluidizing pad inside a conduit connecting the storage tank to the conveyor.

Abstract: A combined leveling bracket and shock absorber for a cabinet is provided which comprises a base plate having a pair of upturned flanges through which the base plate is connected to interior sidewalls of a cabinet in which the bracket is mounted. A foot mounted on a threaded stem adjustably connects into the base plate. A rubber grommet is removably mounted on the threaded stem and is tightly secured against the bracket while the cabinet is in transit. As fastened against the bracket, the grommet provides a shock absorber effect which absorbs impacts during incidental droppage of the cabinet during transit. During installation of the cabinet the foot is threadably disconnected from the base plate and the rubber grommet is removed from the threaded stem. The stem is then rethreaded through the base plate until the foot is suitably adjusted to a desired height for level mounting of the cabinet on a floor or other like surface.
