Patent CA-2262431-C (CA)
Title: Auto-tuned, adaptive process controlled, injection molding machine
Inventor: BULGRIN THOMAS C
IPC: G05B19/416
Filed: 1999-02-23
Granted: 2003-08-19
Abstract: An injection molding machine uses a summed, multi-term control law to control ram velocity during the injection stroke of a molding cycle to emulate a user set velocity profile. An automatic calibration method sets no load ram speeds to duplicate user set ram speeds. Finite impulse response filters produce open loop, no load control signals at advanced positions on the velocity profile to account for lag in system response. An adaptive, error term indicative of load disturbance, observed from a preceding cycle is added at the advanced travel position predicted by the finite impulse response filter to produce a predictive open loop, load compensated control signal. Finally, an auto tuned PID controller develops a real time, feedback load disturbance signal summed with the open loop control signal to produce a drive signal for the machine's proportioning valve.

Title: A method for processing refractory auriferous sulfide ores involving preparation of a sulfide concentrate
Inventor: SIMMONS GARY L
IPC: B03D1/00
Filed: 1997-10-23
Granted: 2002-08-13
Abstract: A method is disclosed for processing a gold-bearing refractory sulfide ore (102) by main-taining the ore in a substantially oxygen free en-vironment, preferably beginning with comminu-tion (104) of the ore and ending after a desired final concentrate, enriched in sulfide minerals, is obtained by flotation (112). In one embodiment, nitrogen gas (110) is used to prevent contact be-tween the ore and air during comminution of the ore (108) and during flotation operations (114).      This invention recognizes that gold in refractory sulfide ores primarily occurs in refractory aurifer-ous sulfides, which arc typically the most difficult sulfide species in the ores to float. By reducing the exposure of those refractory auriferous sulfides to oxygen gas during flotation, flotation recovery is enhanced in the form of a flotation concentrate (116). A flotation tail (118) is also obtained from the process.

Inventor: LEE RON C
IPC: F17C9/00
Filed: 1999-06-21
Granted: 2003-02-04
Abstract: A method and apparatus for storing and dispensing a liquid consisting of an oxygen containing mixture so that the liquid will not contain any more than a predetermined concentration of the oxygen at a predetermined pressure. In accordance with the invention, the mixture is introduced into the container at a specified initial concentration. A hypothetical volume of the saturated state of the liquid having the initial concentration is computed that when expanded into the total volume of the container, the resulting liquid would have the maximum enrichment. The liquid is dispensed from a bottom region of the container and dispensing is prevented when the liquid remaining within the container could possibly have the maximum enrichment computed at a particular dispensing pressure. Pressure relief methods are employed that avoid head space vapor being vented.

Title: Refrigerant fluid injection device and procedure for use with a product mixing apparatus
Inventor: CLOAREC ALAIN
IPC: A23L3/37
Filed: 1999-08-03
Granted: 2007-01-23
Abstract: Typically the mixer has a conical end section closed by a removable cover (14) with a central entry conduit for cooked ingredients. These are frozen separately, or coated in sauce and simultaneously frozen. The refrigerant fluid, e.g. liquid nitrogen, is fed in by an injector nozzle (24), with a vacuum connector (44) for air removal, adjacent to the conduit entry. The delivery pipe (20) includes a flexible hose section, to facilitate cover manipulation, and an elbow (32). Its free end (26), receiving the incoming fluid supply, includes a manually or automatically operated stop valve (28). The pipe includes an electrically controlled interrupter valve (34), opening and closing in synchronism with the mixer's beater to prevent nitrogen impinging on the blades. This valve is placed downstream of a reduced section zone with a calibrated orifice for the expansion of the liquid nitrogen. The elbow (32), downstream of the orifice, effects, through centrifugal forces, a natural separation of the liquid and gaseous phases, creating a liquid stream on the outside of the bend and a gas stream on the inside. A manometer (36) is inserted upstream of the orifice, also a bleed valve (38). To avoid fluid trapping, and facilitate purging, the downstream pipe sections are inclined at e.g. 15 deg. to the horizontal.
