  • Patent number: 4429022
    Abstract: A composite material having improved bond strength and a substantially smooth external surface comprises a deoxidized copper alloy core material and a copper-aluminum-silicon clad material. The composite is formed by rolling together the core and clad, preferably in an unheated condition, in a single pass with a reduction of about 50% to 75% to form a metallurgical bond between the core and clad and thereafter enhancing the bond strength by heating the bonded core and cladding to a temperature in the range of about 200.degree. C. to about 750.degree. C. for a time period of about 5 minutes to about 24 hours.

  • Patent number: 4422900
    Abstract: Granular particles of an available chlorine-containing compound such as sodium dichloroisocyanurate are prepared by conveying a flowing stream of an aqueous slurry of the compound through a tubular chamber under pressure, injecting jets of an atomizing medium such as air into the flowing stream of said slurry to agitate and aerate said slurry, conveying the aerated slurry to an exit port in said tubular chamber, discharging the aerated slurry through said exit port into a zone of reduced pressure and enlarged area, impinging additional jets of an atomizing medium into said slurry as it passes through said exit port, whereby free expansion of said slurry into a cone of aerated droplets of said slurry is effected. The resulting droplets are contacted with a heated gas in said zone to effect evaporation of water from the aerated droplets and thereby produce dry granules of the available chlorine-containing compound.

  • Patent number: 4417959
    Abstract: A novel electrolytic cell for the electrolysis of aqueous solutions of alkali metal chlorides which comprises a cell housing containing a pair of electrodes of opposite polarity. A hydraulically impermeable ion exchange membrane is positioned between and separates the pair of electrodes. At least one of the electrodes comprises a reticulate electrode where the reticulate electrode is in contact with the membrane. Means are provided for applying an electric potential to the electrodes.The reticulate electrode in contact with the hydraulically impermeable membrane forms a composite structure which substantially eliminates the gap between the electrode and the membrane.Employing the novel electrolytic cells for the electrolysis of alkali metal halide solutions results in reduced cell voltages and electrical power consumption. The reticulate electrodes used allow significant reductions in material costs and have increased surface area.
