Title: Chewing gum base manufacturing process using plurality of filler feed inlet locations
Inventor: SONG JOO H
IPC: A23G/
Filed: 1995-03-13
Abstract: A process for continuously producing a chewing gum base comprises the steps of continuously adding a hard elastomer, a filler and lubricating agents into a continuous mixer (10), subjecting the elastomer, filler and lubricating agents to a dispersive mixing operation followed by a distributive mixing operation and continuously discharging the resulting chewing gum base from the mixer while the adding and mixing steps are in progress. The filler is introduced into the continuous mixer at a plurality of spatially separated feed inlets (12, 13 and 15). Preferably part of the filler is introduced into the mixer prior to the dispersive mixing zone, and a portion of the filler is introduced into the mixer downstream of the dispersive mixing zone but prior to the distributive mixing zone.
Patent CA-2200268-A1 (CA)
Title: Low cost corona pre-ionizer for a laser
Inventor: WATSON TOM A
IPC: H01S3/0977
Filed: 1997-03-18
Abstract: An anode and an a cathode in a gas laser, such as an excimer laser, are spaced in a first direction. A voltage difference between these members produces an electrical discharge which ionizes gasses in the laser to react chemically and produce coherent radiation. First and second tubes made from a dielectric material are designed in contradiction to conventional designs by utilizing a constant, larger tube diameter with thicker tube walls. These first and second tubes extend through the laser in a second direction transverse (preferably perpendicular) to the first direction. The anode, the cathode and the tubes extend through the laser in a direction transverse to the first and second directions. The use of a thicker walled, large tube of constant diameter allows the use of a commercial grade polycrystalline aluminum oxide ceramic , rather than ultra pure ceramics. Bushings having anti-tracking grooves incorporated therein are truly integral with the tube, in that they are directly machined at each end of the tube, making the tubes easier and less costly to manufacture. The tube's larger diameter provides a greater surface area for the generation of photons, thereby creating a greater pre-ionizing effect than conventional designs.

Title: High-power diode laser and method for mounting the same
Inventor: DORSCH FRIEDHELM
IPC: H01S5/02
Filed: 1997-09-25
Abstract: The invention is directed to a high-power diode laser and to a method for mounting same. It is substantial to the invention to provide predetermined breaking locations in the laser bar which, during cooling after the laser bar has been soldered to a heat sink having a smaller thermal expansion coefficient, lead to breakage at defined locations between the single laser diodes of the laser bar. As a result of the physical division of the laser bar, it is possible to use a solder which has low ductility (hard solder) at room temperature, since destruction of the single laser diodes of the laser bar as a result of mechanical stresses can be ruled out.

Abstract: Methods for enhancing the production of interferons in animal cell culture are described. These methods rely on the manipulation of the cellular levels of certain inducers of interferon production, in particular cellular levels of double-stranded-RNA-dependent kinase (dsRNA-PKR, or PKR). In cell cultures that overproduce PKR, interferon synthesis is induced to high levels, and significant amount of interferon can be recovered without conventional induction of interferon by virus.
Patent CA-2229911-A1 (CA)
Inventor: BAXTER MICHAEL S J
IPC: A61M5/50
Filed: 1998-02-19
Abstract: A non-reusable syringe using the weakness in compression compared to strength in tension of a structural member treat is relatively long compared to its section to provide a syringe which in the ordinary course of expelling liquid from the syringe renders the syringe difficult to reuse.      A section. of the plunger is reduced in section to the point where it is strong enough to pull the piston in order to draw liquid into the syringe but will fail when the plunger is depressed to expel fluid. The plunger remains capable of pushing the piston to expel the liquid but can not be used to retract the piston as it is disconnected from the piston.
Patent CA-2233184-A1 (CA)
Title: Dual valve fitting for enabling quick measurement of pressure
Inventor: JOHNSTON GREGORY L
IPC: F16L37/28
Filed: 1998-03-26
Abstract: A dual valve fitting enables quick measurement of pressure contained within a housing. The fitting includes a valve body, a valve retainer, first and second sealing rings and a biasing mechanism. The valve body defines a flow passage within which is situated the valve retainer. The valve body is designed at its protuberant end to mate with a female coupler of a quick connect device and at its threaded end to screw into a threaded bore of the housing. The valve retainer defines around itself first and second annular recesses each of which spaced apart from the other to match the spacing of outer and inner annular valve seats formed in the flow passage. Forming a first valve, the first sealing ring retains in the first annular recess so as to be seatable against the outer valve seat. Forming a second valve, the second sealing ring retains in the second annular recess so as to be seatable against the inner valve seat. The valve retainer is biased within the flow passage so that the first and second sealing rings seat against the outer and inner valve seats, respectively, thereby rendering the first and second valves normally closed. Mating the female coupler to the protuberant end of the fitting causes the valve retainer to move inwardly against the biasing mechanism so as to open both the first and second valves thereby allowing flow from the housing through the flow passage and into the female coupler.
