Patent CA-2247730-A1 (CA)
Inventor: MILLER ROBERT L
IPC: A23B7/06
Filed: 1998-09-21
Abstract: A process is disclosed for inhibiting enzymatic browning in raw, peeled potatoes comprising dipping the potatoes in a solution of heated organic acids (45-65°C), followed by treatment in a weakly basic solution to neutralize the potato surface and treatment with reducing agents, followed by storage in modified atmosphere packaging. The process may comprise two stages, in which sodium erythorbate in solution (approximate pH 7.8) is used both as the neutralizing agent and the reducing agent. Alternatively, the process may comprise three stages, inwhich a solution of the salt of an organic acid (such as sodium citrate) is used to neutralize the potato surface following the heated acid dip, and a third stage containing the reducing agents sodium erythorbate and erythorbic acid are combined at a final pH of greater than 4.3. Chelating agents or sequestrants maybe added to the solutions. The process tends to delay the onset of enzymatic browning and, once browning has begun, limits the extent of enzymatic browning. The novel process causes little or no hardening or separation of the potato surface tissue in the final cooked product, and is potentially an alternative to the present use of sulfites for raw, peeled potatoes.

Patent CA-2265499-A1 (CA)
Inventor: LUCAS DERICK ROSS
IPC: F04F5/34
Filed: 1997-09-08
Abstract: A pump for both filling and emptying containers with liquids, flowable solids, etc. has a body (20) which is screwed into a bung hole (15) in the top wall of the container. According to the state of evacuation or pressurisation produced in the container by the pump, "liquid" will enter or leave the container via pipe (21) passing through the body (20) of the pump. The motive power for the pump is a compressed air source (14) which provides air to a venturi (31) positioned in a passage (24) connecting the interior of the container with the exterior via vented (27) chamber (25). Air flowing through air ports (32) in the venturi generates a vortex which creates air flow through passage (24). By turning handle (29) the venturi may be rotated so as to reverse its orientation and thus reverse the direction of air flow to either pressurise or evacuate the container. Alternatively a pair of oppositely-directed venturis selectively connectable to air passage (24) may be used to perform the emptying and filling functions.

Title: Semiconducting polymer composition and cable sheathing comprising the same
Inventor: AKERMARK GUSTAV
IPC: C08J3/24
Filed: 1997-07-02
Abstract: A semiconducting, cross-linkable and silane-containing polymer composition is disclosed, as is a cable sheathing for an electric cable which, as semiconducting layer, includes the cross-linked polymer composition.  The composition is based on ethylene and contains carbon black. Preferably, the polymer is a terpolymer of ethylene, a (meth)acrylate of an alcohol having 1-8 carbon atoms, such as methyl, ethyl or butyl acrylate, and an unsaturated silane compound, such as vinyltrimethoxy silane. The polymer composition is distinguished by the fact that the carbon black has a specific surface area of approximately 30-80 m2/g, which reduces the problems associated with undesirable croos-linking of the polymer composition, for instance in extrusion.

IPC: G06T5/00
Filed: 1999-06-14
Abstract: A computer system and a method to segment two dimensional Magnetic Resonance Images that include a substructure is disclosed herein. The method consists of first receiving a set of MRI.      The segmentation is then performed by the user on the first image of the set. Using this information, the system proceeds with the segmentation of the other images in the set, by first, estimating the center position of the substructure. The system then find the pixel of the substructure's contour for different angular positions about the center of the substructure. This is achieved by the system by predicting the contour position and using that predicted position to find the position of the pixel belonging to the contour that corresponds to the current angular position.      Having connected the pixels of the contour, the system fills the substructure.

Title: Deformable intraocular corrective lens
Inventor: CALLAHAN JEFFREY S
IPC: A61F2/16
Filed: 1999-10-04
Abstract: A deformable, artificial intraocular corrective lens for implantation into the human eye to correct normal vision problems. The lens may be positioned posteriorly from the iris, resting against the anterior surface of the posterior capsule's natural lens. Alternatively, the lens may be positioned in the anterior chamber of the eye. The implanted lens works in conjunction with the cornea and natural lens to provide proper vision, as a substitute for regular contact lens, spectacles, and radial keratotomy. The lens may be designed from a rigid or semi-rigid material. Due to the thinness of the structure, the lens may be rolled and inserted into the eye, minimizing both the length cf the corneal incision and the stretching of the cornea.
