Patent CA-2068993-A1 (CA)
Title: Cooling process and apparatus
Inventor: MORRIS GEORGE J
IPC: F25C1/00
Filed: 1990-11-20
Abstract: Material to be frozen is subjected to a cooling process which involves the application of sound waves, such as ultrasound. The invention has particular application in the frozen food products as margarine, chocolate and ice cream but may also be applied to freeze drying and cryopreservation processes. The material being frozen may also be subjected to a cooling regimen which efficiently removes the latent heat of freezing, for example by increasing the heat extraction rate when the latent heat of freezing is being given up. The invention may permit shorter freezing times and/or improved viability of the frozen or solid product.
Patent CA-2069346-A1 (CA)
Inventor: TAKECHI RYUICHI
IPC: H04L12/70
Filed: 1992-05-25
Abstract: An ATM cell error processing system includes a plurality of error detectors for respectively detecting predetermined cell errors and for respectively generating decision signals, an error editing unit which is operatively coupled to the error detector and determines, on the basis of the decision signals, whether or not a cell related to the decision signals should be discarded.  A buffer, which is coupled to at least one of the error detector, temporarily stores the cell.  An error cell discarding unit, which is coupled to the error editing unit and the buffer, discards the cell from the buffer when the error editing unit determines that the cell should be discarded and relays the cell when the error editing unit does not determine that the cell should be discarded.

Title: Power-up and initialization of a multiprocessor system
Inventor: RAPATZ BRIGITTE R
IPC: G06F1/24
Filed: 1992-05-29
Abstract: ABSTRACT             POWER-UP AND INITIALIZATION OF A MULTIPROCESSOR SYSTEM    Initialization of a multiprocessor system with only one nonvolatile memory element is disclosed.  The multi-processor system is made up of a nonvolatile memory for storing a boot program, a master main program and a sub-system main program.  Several subprocessors, where each subprocessor is made of:  1) A local processing unit that executes the boot program and the subsystem main program; 2) A local memory that stores the subsystem main program; 3) A dual port memory that has a first and a second port the local processing unit is connected to the second port of the dual port memory; and 4) A local selector that selects whether the local processor unit retrieves pro-gram code from the local memory or the dual port memory. When the local processing unit is executing the boot pro-gram, the local select selects the second port of the dual port memory, in the alternative, when the local processing unit is executing the subsystem main program, the local select selects the local memory.   Finally, a master processor is connected to the first port of all of the dual port memories and to the nonvolatile memory. The master processor, under control of the master main pro-gram, transfers the boot program and the subsystem main program to the first port of the dual port memory.  Also the master processor controls all the local selectors.

Abstract: A wide area type of wet press for dewatering an endless traveling web, such as paper, wherein a shoe having a curved face is applied to a traveling belt which travels through a high pressure zone between the shoe and a rotating backing roll.  The nip line of the most intense nip pressure along the length of contact of the shoe over the backing roll is selectively located, as desired, by pivotally supporting the shoe about two, parallel, longitudinally extending axes which, in turn, are supported on separately controlled hydraulic pistons.  The pressure profile of the nip pressure over the face of the shoe can also be altered by controlling the hydraulic pressure in the support pistons.

Patent CA-2085032-A1 (CA)
Title: Rollover method for metal casting and apparatus therefor
Inventor: SEATON WILLIAM W
IPC: B22D27/08
Filed: 1992-12-10
Abstract: Abstract A method and apparatus for making a metal-lurgically improved metal casting (10) with increased productivity, wherein molten metal is quiescently fed upwards into a molding chamber (14) which is then inverted.  The disclosed system uses an assembly of refractory cores (12) that define the molding chamber (14) with riser channels (16).  A metal entrance (18) to the molding chamber (14) through a mold side wall (20) requires feeding molten metal against gravity to fill the molding chamber (14), and quiescently pres-sure feeding molten metal through a metal launder (26) to fill the molding chamber (14) and the riser chan-nels (16).  A mold/nozzle connection between the metal launder (26) and the source of molten metal delivered under pressure is rotationally flexible and axially compliant.  The feeding of molten metal is interrupted and the assembly is rotated about an axis passing through the mold/nozzle connection (28) to invert the assembly while maintaining the mold/nozzle connection. The mold/nozzle connection (28) is then severed from the inverted assembly.  Molten metal is then allowed to feed under gravity into the molding chamber (14) from the riser channels 16 and the metal launder (26) is drained.  Meanwhile, the molding chamber (14) is removed from the mold/nozzle connection (28), and a subsequent mold is filled.

Title: Process for making as-cast ferritic spheroidal graphitic ductile iron
Inventor: WILFORD COLIN F
IPC: C21B11/10
Filed: 1990-07-12
Abstract: A process for making ferritic spheroidal graphite iron uses no pig iron but instead melts medium manganese and low silicon content steel scrap in an electric furnace with about 3 % by weight of low sulphur content graphite. When the melt reaches 1400 ·C it is deslagged. Sufficient graphite is then added to bring the carbon up to at least 3 % again and before or after this event, returns may be added to the melt while the furnace electric power is on to induce stirring of the melt. The melt is superheated next to above 1470 ·C and carbon and silicon correction is made. This is followed by inoculating the melt and pouring the castings.

These microcapsules  are preferably prepared by a method which includes laminar-flow extrusion dislocated by individual droplet vibrations falling into a coagulation bath.       The  presence  of the atelocollagen renders  the microcapsules   biocompatible.  They  are   particularly suitable  for the production of cosmetic, pharmaceutical or food compositions.
Patent CA-2088668-A1 (CA)
Title: Battery charge indicator
Inventor: BOHMER WILLIAM
IPC: H01M50/569
Filed: 1992-06-03
Abstract: A battery charge indicator is permanently incorporated into a battery to indicate the state of charge. The indicator includes a compressible chamber which is filled with a viscous gel and which is exposed to the expansible cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet (13a) into a viewing channel (12a, 12b, 12c) in an overlying disk (12). The amount of gel flowing into the viewing channel is proportional to the amount of expansion of the cathode and, thus indicates the amount of discharge and, conversely, the remaining life of the battery.

Title: Coupling antiwindage rings
Inventor: WYNN ROBERT C
IPC: F01D5/02
Filed: 1993-05-07
Abstract: ABSTRACT OF THE DISCLOSURE          An anti-windage device is provided for use on the couplings formed by mating flanges of rotors for turbomachines, such as steam turbines and the like.  The anti-windage device is comprised of upper and lower anti-windage ring segments.

The holes enclose the nuts and the anti-windage ring segments fill the circumferential spaces between adjacent nuts.  The ring segments are secured to the rotor flange by causing the nuts to bear against an annular lip formed in each hole. The depth of the holes and the axial thickness of the anti-windage ring is such that the end faces of the anti-windage ring, nuts and bolts are flush, thereby forming a smooth surface that minimizes windage.
