Title: Oil body proteins as carriers of high value proteins
Inventor: MOLONEY MAURICE
IPC: C12N15/29
Filed: 1995-12-21
Abstract: The present invention relates to the use of a class of genes called oil body protein genes that have unique features. The discovery of these features allowed the invention of methods for the production of recombinant proteins wherein a protein of interest can be easily separated from other host cell compo-nents. The invention is further exemplified by methods for exploitation of the unique characteristics of the oil body proteins and oil body genes for expression of polypep-tides of interest in many organisms, partic-ularly plant seeds. Said polypeptides may include but are not limited to: seed storage proteins, enzymes, bioactive peptides, anti-bodies and the like. The invention can also be modified to recover recombinant polypeptides fused to oleosins from non-plant host cells. Additionally the invention provides a method of using recombinant proteins associated with seed oil bodies released during seed germination for expression of polypeptides that afford protection to seedlings from pathogens. Finally, the persistent associa-tion of oil body proteins with the oil body can be further utilized to develop a bio-logical means to create novel immobilized enzymes useful for bioconversion of sub-strates.

Patent CA-2234238-A1 (CA)
Title: Cleaner with inverted hydrocyclone
Inventor: GRIMES DAVID B
IPC: B04C5/085
Filed: 1996-09-19
Abstract: A cleaner receives input pulp stock in an inverted conical chamber (26), which acts as a hydrocyclone to direct heavyweight reject flows outwardly, lightweight reject flows into a discharging vortex chamber and accept flows in between to a vortex finder for removal. The cleaner body has an inverted hydrocyclone chamber (34) formed beneath the inverted cone and a ceramic splitter (36) below which skims off the heavyweight reject flow from the accept flow, and diverts it into the inverted hydrocyclone chamber (34). A  portion of the diverted heavyweight reject flow is removed through a toroidal heavyweight rejects relief outlet (47), but the larger fraction of the heavyweight reject flow is recirculated within the inverted hydrocyclone chamber. Because the chamber narrows as it extends upwardly, the flow increases in speed and angular velocity to such an extent that the flow within the inverted hydrocyclone chamber matches the flow passing by the chamber, thereby preventing turbulent mixing.
Patent CA-2234266-A1 (CA)
Title: Method of forming articles using thermosetting materials
Inventor: BOOTH RICHARD B
IPC: B22F3/10
Filed: 1996-10-10
Abstract: A method of fabricating articles, such as prototype parts and prototype tooling for injection molding, is disclosed. The method begins with the fabrication of the article in a "green" state by the selective laser sintering, or another additive thermal process, applied to a composite powder, preferably a powder of metal particles coated with a thermoplastic polymer.  Both the green article and also an aqueous emulsion of a thermosetting material are then preheated to a temperature below the glass transition temperature of the thermoplastic polymer, and the green article is then infiltrated with the aqueous emulsion. The thermosetting material may be a thermosetting polymer with an appropriate cross-linking agent, or may be a cross-linking agent that will react with the thermoplastic binder polymer.  After infiltration, the article is dried, and a rigid skeleton of a thermosetting material is now present within the structure of the article.  Further processing may now be performed. The article may be heated beyond the decomposition temperature of the polymers so as to drive off the polymer and sinter the metal particles to one another; alternatively, a resin may be added to the article to form a metal-polymer composite article. High strength articles may thus be formed in a manner which preserves the dimensional accuracy of the article relative to its CAD representation.

Title: Heating device for machines for the transformation of plastic materials
Inventor: COLLOMBIN ANDRE-MARCEL
IPC: B29C49/68
Filed: 1996-09-23
Abstract: The heating device for a machine for transforming plastic materials, comprises a heating body (39) disposed between two parallel rows (41, 42) of preforms (14). It is provided with at least two heating tubes (40) having bidirectional heating blades (54). These latter are inclined at an angle (.alpha.) such that a first of their faces emits heating radiation (55) in the direction of the adjacent row of preforms and such that the second surface emits its heating radiation (56) substantially in the direction of the free space between the two opposite rows of heating tubes toward the farthest row of preforms. Reflectors (60) are moreover arranged so as to reflect the heating radiation in a horizontal plane toward the preforms (14). The device thus permits obtaining very high energy efficiency whilst avoiding a harmful elevation of the temperature of the machine into which it is integrated.
