Title: Process for the production of refined edible oils and products for feedstuff animal industry from vegetable or animal raw oils and absorbent silicas
Inventor: WALSH GEORGE R
IPC: A23D9/00
Filed: 1998-07-09
Abstract: There are numerous processes to refine vegetable or animal oils. All of these processes give by-products with little or no value and pollutant effluents.      In this invention we have found that these disadvantages can be overcome by treating directly the raw oil with absorbent silicas produced particularly by precipitation of alkali silicates with acids.      The oil is then separated from the silica saturated with the molecules other than triglycerides. The saturated silica which holds back a small amount of oil becomes a good product for feedstuff animal industry with a good energetic value.      No wastes nor effluents occur in the process.

Abstract: Absorbent articles, particularly sanitary napkins, having elastically extensible, laterally extending flaps are disclosed. The flaps are further provided with a means for attaching them to a wearer's panty. At least a portion of the elastic extensibility has a vector component in the longitudinal direction. This longitudinally oriented elastic extensibility provides a contractive force which causes the absorbent article to assume an arcuate shape that more readily conforms to the wearer. Further, the extensibility allows the flaps to extend and contract with the edges of the leg openings of the wearer's panty so the flaps are more reliably adhered to the panty.
Patent CA-2248721-A1 (CA)
Title: A computer system and process for defining and manufacturing images using structured objects with variable edge characteristics
Inventor: WONG SZE-PING
IPC: G06T15/00
Filed: 1997-03-05
Abstract: An image representation using a structured object may be readily manipulated by a computer. This image representation can represent more complex images where the structured object defines a boundary for which image values near the boundary in a region are defined by a function called an edge characteristic function. The edge characteristic function is applied by determining, for each point in the region, a point on the boundary to which the given point is closest, herein called an anchor, and a distance to that point. Different edge characteristic functions may be assigned to different points along the boundary. In one embodiment, edge characteristic functions are assigned to selected for characteristic points on the boundary. These edge characteristic functions may be interpolated to provide edge characteristic functions for remaining points along the boundary. Each point not on the boundary is processed according to the edge characteristic function of the point on the boundary to which it is closest and according to the distance to that point. An edge characteristic function may also be a function of other factors. This image representation provides many benefits including the ability to generate more complex images which can then be manipulated more easily or be converted from different image formats. One form of manipulation is interpolation over time. In image compositing, this image representation also allows for easy attenuation of various effects over regions in a controlled way.

Patent CA-2249953-A1 (CA)
Title: Tamper-evident container closure
Inventor: CONTI RINO
IPC: B65D25/32
Filed: 1998-10-09
Abstract: A tamper-evident closure for a container is provided. The container is formed with means at its open upper end for making a snap fit locking connection with a cover. The container has a peripheral flange with a skirt section that surrounds and is spaced radially from the container's side wall, and the cover has a depending skirt that extends down around the upper end of the container and has a free bottom edge that lies immediately adjacent to the flange. The flange has an outer surface that is flush with the adjacent portion of the outer surface of the skirt, so that essentially the flange appear to be a continuation of the skirt. As a consequence the closure formed by the cover (lid) and the container is resistant to opening by a small child. Additionally the skirt section of the flange has a tab portion that is breakable under pressure so that, once broken, it can be depressed inwardly toward the container side wall far enough to permit a person to engage the bottom edge of the skirt on the cover and thereby force the cover off of the container. The tab portion functions as a tamper evident feature, since the fact that it has been broken can be easily discerned from inspection and since the torn tab cannot be restored to its original condition.
