Patent CA-2284913-A1 (CA)
Inventor: SHAH PANKAJ SHASHIKANT
IPC: C08B37/00
Filed: 1998-03-19
Abstract: Superior quality, clean-tasting food grade polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels of a polycarboxylic acid such as citric acid. In one embodiment, polydextrose is prepared by reacting glucose or glucose-containing materials such as hydrolyzed starch with a polyol such as sorbitol in the presence of low levels, i.e., from about 0.03 % to about 0.1 %  citric acid at a temperature of from about 145 to about 185 °C, preferably from about 150 °C to about 160 °C. Because of the low levels of catalyst used in preferred embodiments, minimal or no off-flavors and little color are formed during the course of the reaction, but the product may be purified using ion exchange, membrane filtration, or carbon treatment, or further modified by hydrogenation if desired for certain applications.

Patent CA-2315202-A1 (CA)
Title: Asynchronous transfer mode switch
Inventor: BROBERG HANS MAGNUS
IPC: H04L12/56
Filed: 1998-12-15
Abstract: An asynchronous transfer mode (ATM) switch (20) has plural switch ports (24) connected by respective bidirectional links (27, 28) to a switch core (22). Connected to each switch port is a corresponding row column unit (40), each row column unit managing the writing of service cells to one row of cross point units (32) and the reading of service cells from one column of cross point units. The bidirectional links between each switch port and its corresponding row column unit of the switch core carry both service cells and control cells. An interactive exchange of control cells is implemented to sequence operation of the switch core. The operations particularly dependent upon control cell generation include transmission of service cells from the switch core; transmission of pollstate control cells from the switch core; retrieval of contents of certain control registers maintained by the switch core; and synchronization procedures. Pollstate information, indicative of "occupied"/"free" status of selected ones of the cross point units, is transmitted in pollstate control cells. The pollstate control cells are generated and transmitted either (1) in response to a particular control cell evocative of the pollstate information, or (2) upon a change of absence/presence (e.g., free/occupied status) of a predetermined number of the affected cross point units.

Abstract: A non-planar seal between a container having a base and lid. The base has a rim which includes a first seal component. The lid has a rim which includes a second seal component. The first and second seal components interact to provide a seal, for example a water-tight seal, when the lid is mounted to the container to thus protect the contents of the container. The seal is formed along a locus of points defining a non-linear plane, or curved surface. The first and second seal components are oriented so as to extend substantially normal to the non-linear plane at any given point along the seal. This arrangement permits greater design possibilities due to fewer restraints on seal component placement, while still providing excellent sealing properties for the container.

Patent CA-2319222-A1 (CA)
Inventor: HILDE DAVID RONALD
IPC: A61F5/445
Filed: 2000-09-08
Abstract: The invention is designed to protect an Ostomate's stoma from coming in contact with an Ostomy waste pouch that is normally worn by a person who has a colostomy and must use ostomy appliances and waste pouches.        The Stoma Protector shield is comprised of a semi circular tube with a circular flange on the bottom of the tube. The tube rises vertically above the flange to a designated height from the base of the structure. 35% of the verticle tube is cut away leaving an opening on the surface of the tube. The tubular structure is open at both ends.      The height of the tubular section is sized to the average size of an Ostimate's stoma. The material used in the manufacture of the protector shield can be plastic, metal, or what ever material is deemed best.      The shield is placed between the ostomy appliance wafer inside the wafer's flexible collar next to the surface of the appliance. Then the Ostomy waste collecting pouch is placed on the appliance connecting the pouch to the appliance in the normal fashion. The protector shield is now held in place by the collar of the ostomy pouch, thus preventing the protector shield from becoming loose and falling into the pouch.

Abstract: The purely bound electromagnetic modes of propagation supported by asymmetric waveguide structures comprised of a thin lossy metal film of fini te width on a dielectric substrate and covered by a different dielectric superstrate have been characterized at optical wavelengths. The dispersion of the modes with film thickness and width has been assessed and the effects caused by varying the difference between the superstrate and substrate dielectric constants on the characteristics of the modes have been determined. In general, the modes supported by these structures exhibit some characteristic s that are consistent with those observed for the modes supported by similar symmetric structures and asymmetric slab guides. Like symmetric structures, the higher order modes have a cutoff width below which they are no longer propagated, and some of the modes have a cut-off thickness. Unlike symmetric structures, all modes that have a decreasing attenuation with decreasing fil m thickness have a cutoff thickness. Under certain conditions, an asymmetric structure can support a long-ranging mode having a field distribution that i s suitable to excitation using an end-fire technique. Like asymmetric slab waveguides, the attenuation of the long-ranging mode near cutoff decreases very rapidly, much more so than the attenuation related to the long-ranging mode in a similar symmetric structure. The cutoff thickness of a long-rangin g mode in an asymmetric finite-width structure is larger than the cutoff thickness of the s b mode in a similar asymmetric slab waveguide. This implies that th e long-ranging mode supported by an asymmetric finite-width structure is more sensitive to the asymmetry in the structure compared to the s b mode support ed by a similar slab waveguide. This result is interesting and potentially usef ul in that the propagation of such a mode can be affected by a smaller change in t he dielectric constant of the substrate or superstrate compared with similar sl ab structures.
