Title: Method for producing iron-manufacturing raw material comprising dissolution residue of bauxite
Inventor: TANJO MITSUO
IPC: C01F7/066
Filed: 1993-03-30
Abstract: ABSTRACT          An iron manufacturing raw material comprising a dissolution residue of bauxite containing 3 % by weight or less of Na2O and 10 % by weight of loss on ignition is prepared by mixing bauxite and an alkaline solution to form a slurry, charging said slurry in an extractor, extracting alumina under conditions that most of the alumina which is extractable from bauxite is extracted while dissolution of reactive silica is suppressed as much as possible, separating an extract and a dissolution residue while the reactive silica which is dissolved in the extract is no precipitated substantially as a desilication product, and washing and dehydrating said separated dissolution residue.           By this method, it is possible to use the bauxite dissolution residue which finds no economical use, as the iron manufacturing raw material.

Patent CA-2135419-A1 (CA)
Title: Liquid dispensing system
Inventor: PATTERSON JAMES
IPC: B05B1/08
Filed: 1994-11-09
Abstract: ABSTRACT OF THE DISCLOSURE     A water cannon is arranged for both pulsed and continuous flow.          A turret is provided for supporting and aiming a water cannon nozzle.  Advantageously, the water cannon includes a pump which accelerates water through a closed loop until operation of a valve directs the water to the turret.  In the pulsed mode, a second valve keeps the nozzle normally closed, and the flow causes pressure in an air chamber to increase above a predetermined level, thereby opening a second valve and allowing the water to exit the nozzle.  This flow reduces the pressure in the air chamber below the predetermined level.  As a result, the second valve is actuated to stop the flow.          In the continuous flow mode, the second valve is maintained open to allow the flow directed from the closed loop to exit the nozzle in a continuous flow.
Patent CA-2136025-A1 (CA)
Title: Piston Unloader Arrangement for Screw Compressors
Inventor: ANDERSEN GARRY E
IPC: F04C28/26
Filed: 1993-02-01
Abstract: A screw compressor employs a piston unloader which is disposed in a bore remote from the compressor's working chamber. Flow communication between the bore and working chamber is through a series of non-overlapping unloader ports. The unloader piston has a notched end face which effectively causes the unloader ports to overlap in operation. Precise and continuous capacity control of the compressor over a predetermined portion of its operating range is thereby achieved while internal high to low side gas leakage within the compressor and the clearance volume of the unloader ports is minimized.  Compressor efficiency is thereby increased.
