Patent CA-2369221-A1 (CA)
Inventor: KEESLER GLENN R
IPC: B21D39/00
Filed: 2002-01-23
Abstract: A convertible flange insertion machine for the insertion of a pair of internally threaded flanges into a drum head of a shipping container is disclosed.   The machine includes a pair of continuously moving drum head conveyor chains running along conveyor supports and between a pair of tooling dies that upon compression insert flanges into the drum head. A pair of flange conveyors run along side the drum head conveyor and include a pair of side rails with two lips for guiding the lips of flanges according to two different flange styles. The flange conveyors terminate at a lateral transfer mechanism. One lateral transfer mechanism includes an indexer with two pawls that sequentially indexes flanges in a two step procedure over a pair of spring loaded stops and into the receiving pocket of a tooling block. The tooling block places the flanges over the tooling die where a release assembly forces the flanges out of the tooling block and onto the die. Another lateral transfer mechanism includes an indexer that directly indexes flanges laterally off a floor to be dropped into the die, and the indexer includes a flange engaging portion that holds the trailing edge of the flange to prevent the flange from tipping while it drops into the die. The drum head is placed over the flanges and the die portions compress, which lowers the conveyor supports and causes the drum head to come to rest on the lower die portion, and insert the flanges into the drum head. The machine is operable in both a one-step and two-step flange insertion procedure.

Title: Novel intermediate and processes for its preparation and conversion into a pharmacologically-active agent
Inventor: RATHOD DHIRAJ MOHANSINH
IPC: C07C49/84
Filed: 2002-04-09
Abstract: Processes for the preparation of Venlafaxine (IX) via the novel epoxy-nitrile intermediate (I), which when subjected to hydrogenation forms compound (X), and may subsequently be reduced to yield the desired product (IX). The epoxy-nitrile intermediate (I) itself may be synthesised via various alternative reaction strategies, from a range of starting materials. E.g. 4-methoxy-benzaldehyde (VI), upon treatment with cyclohexyl magnesium bromide yields compound (V). This in turn may be oxidised to yield compound (III), which forms compound (II) on treatment with an .alpha.-keto-halogenation agent. Cyanation of compound (II), then yields the desired epoxy nitrile intermediate (I), from which Venlafaxine (IX) may be synthesised.

Title: Recovery and re-use of anode oxygen from electrolytic cells
Inventor: BELLINO MARK
IPC: C25C1/08
Filed: 2002-07-09
Abstract: A process and apparatus for recovering a metal from a feedstock containing a compound of the metal. The process includes an electrowinning step in which a leachate comprising a salt of the metal, dissolved in an aqueous acid solution, is subjected to electrowinning in an electrolytic cell, wherein elemental metal is deposited on the cathodes of the cell and oxygen is generated at the anodes. The oxygen generated at the anodes is collected and is then at least partially consumed in an oxygen-consuming step of the process. Preferably, the oxygen-consuming step comprises an atmospheric or pressure leaching step in which the metal compounds in the feedstock become dissolved in a leachate in the form of metal salts, preferably sulfates. The recovery and use of anode oxygen in a leaching process encourages the use of mist-reducing technology in existing and new electrowinning facilities.
