Patent CA-2067910-C (CA)
Title: Improved fluid catalytic cracking process featuring reduced feed stock particle size
Inventor: MARTINEAU ANDRE
IPC: B01J8/24
Filed: 1992-05-06
Granted: 2000-08-08
Abstract: In fluid catalytic cracking of oils, the feedstock oil is atomised so that its average particle size relative to the average catalyst particle size is such that most oil particles contacting a catalyst particle will form a film having a thickness substantially less than the boundary layer thickness of the thermal conduction interface between the feedstock oil and the catalyst. A nozzle suitable for producing such atomisation is disclosed. To compensate for reduced formation of coke from the feedstock, and permit riser temperatures to be maintained without overcracking, decant oil or other oil residues containing uncrackable hydrocarbons may be added to the feedstock so as to obtain gasoline fractions having increased octane numbers.

IPC: A23L33/155
Filed: 1992-06-17
Granted: 2006-03-21
Abstract: Solid ascorbic acid particles of less than 38 microns in size are shown to be effective antioxidants for substrates in which ascorbic acid is insoluble, such as animal and vegetable oils, essential oils, carotenoids, and the like, at weight concentrations of 0.02% and even at 0.005% or below. these particles are preferably prepared by wet milling ascorbic acid in a medium in which it is insoluble, until the size is lass than 38 microns, and preferably less. Employment of such particles in a medium in which they are insoluble, as well as employment in the stabilization of fats, oils, and foods, is demonstrated.

Title: Countergravity casting apparatus and method
Inventor: CHANDLEY GEORGE D
IPC: B22D33/02
Filed: 1993-03-15
Granted: 1999-09-21
Abstract: A method for the countergravity casting of a melt involves placing a refractory mold in a vacuum chamber defined within a casting box where the mold may be optionally surrounded by support particulates in the vacuum chamber. The mold includes a mold cavity and a serpentine melt inlet passage formed by nested refractory members below the mold cavity and in melt flow communication therewith. The serpentine melt inlet passage is communicated with a fill tube extending from the casting chamber toward an underlying source of melt. The mold/chamber and the source are relatively moved to engage the fill tube and the source. A differential pressure is applied between the mold cavity and the source to urge the melt upwardly through the fill tube and serpentine melt inlet passage into the mold cavity. The mold/chamber and the source are then relatively moved to disengage the fill tube and the source after the mold cavity is filled with the melt. The mold/chamber as a unit is rotated in a direction that the serpentine melt inlet passage prevents runout of melt from the mold cavity until the mold/chamber are inverted.

Granted: 2002-12-10
Abstract: A method for encapsulating biologically-labile materials such as proteins, liposomes, bacteria and eucaryotic cells within a synthetic polymeric capsule, and the product thereof, are disclosed. The method is based on the use of a water-soluble polymer with charged side chains that are crosslinked with multivalent ions of the opposite charge to form a gel encapsulating biological material, that is optionally further stabilized by interactions with multivalent polyions of the same charge as those used to form the gel. In the preferred embodiment, hydrolytically stable polyphosphazenes are formed of monomers having carboxylic acid side groups that are crosslinked by divalent or trivalent cations such as Ca2+  or Al3+, then stabilized with a polycation such as poly-L-lysine. A variety of different compositions can be formed from the crosslinked polymer. In a preferred embodiment, microcapsules are made by spraying an aqueous solution of polyphosphazene and material to be encapsulated into a cal-cium chloride solution. A semi-permeable membrane is formed on the microspheres by complexation of the surface carbox-ylate groups with poly(L-lysine).
