摘要： A conventional kettle for the vacuum dezincing of lead is conventionally provided with an outer bearing flange for supporting the kettle on a frusto-conical frame. This apparatus is further provided with a ring-shaped space outside the kettle which extends from the top of the kettle to the bearing flange and which is closed to the ouside of the kettle but open to the inside of the kettle through an annular clearance. This ringshaped space reduces the tendency of the kettle to crack between its upper edge and the bearing flange, and thereby increases the useful life of the kettle.

摘要： Method for improving the recovery of nickel by magnetic separation of the product resulting from the treatment of a nickeliferous initial material by a segregation process, characterized in that the nickeliferous initial material is obtained by mixing laterite and a second type of ore in which the acid value, i.e., the ratio of the oxygen content of the silica contained in the ore to the oxygen content of the basic components of said ore, is greater than one.

摘要： The invention comprises a portable metering apparatus for supply of low viscosity materials in measured quantities and intended mainly for handling charges of explosive material such as ammonium nitrate and fuel oil, said apparatus comprising a hopper for the material to be metered, a horizontal cylinder located beneath the hopper and having a piston member mounted therein, which piston member includes a first and second section spaced axially apart to provide a transfer passage and a metering device into which material flows by gravity from the hopper through the transfer passage into a measuring chamber incorporated in the metering device until the piston is actuated to cut off the flow and permit discharge of a measured amount of material from said chamber. A metering plunger is adjustably mounted within the measuring chamber by which its capacity can be pre-set to measure a give quantity. The cylinder has inlet and outlet orifices for connection respectively to the hopper and the metering chamber. The piston member is urged, e.g. by spring means, to a normal or open position in which the hopper remains in communication with the metering chamber through the transfer passage to permit of transfer of material by gravity from the hopper to said chamber, pneumatically operated means being provided for effecting displacement of the piston member to an operative or release position to cut off the flow of material from the hopper and permit release of the measured quantity in the metering chamber.
