Patent CA-2336239-A1 (CA)
Inventor: CLAY TYMEN
IPC: B23B27/04
Filed: 2001-03-01
Abstract: A cutting tool piece is provided including a rear portion and a lead portion, the lead portion including a front section having an upper side angled downwardly and forwardly and a lower side angled upwardly and forwardly to form a transverse lead cutting edge. The rear portion includes a hole to secure the tool piece to a cutting tool and transverse cutting edges extending outwardly from side walls of the front section. Use of the tool piece prevents catching of the tool and excess vibration when it is secured to the end of the cutting tool and applied to a rotating wood block on a lathe. A system is also described for cutting a bowl from a wood block by coring out an interior portion of the wood block by applying the cutting tool which is curved and rotatably mounted to a post. Its lead end with the tool piece attached creates a circular groove about the lathe rotational axis in the wood. The cutting tool is advanced on a path which curves toward the central axis of the lathe. A curved support member of the same curvature as the cutting tool is rotatable about a support post and is positionable below the cutting tool.

Title: System, apparatus and method for paging optimization using sub-location areas
Inventor: BORG GUNNAR
IPC: H04W68/00
Filed: 1999-07-08
Abstract: A telecommunications system, apparatus and method is disclosed for optimizing the use of paging channels within the network by dividing location areas (LAs) into sub-location areas (sub-LAs) and providing a more efficient and flexible method of paging mobile subscribers. The amount of usage of the paging channels and the number of location updates performed by a mobile subscriber can be monitored by the network to determine either statistical data or a subscriber category, e.g., heavy-user or light-user, which can be stored within the Subscriber Identity Module (SIM) card within the mobile station (MS). The sub-LA information along with the LA information for the cell that the mobile terminal is in is broadcast and monitored by the SIM card within the MS, which can then perform location updates based upon the category or data. The Mobile Switching Center/Visitor Location Register can also use the data or category for paging purposes, e.g., either page within the entire LA or within only the sub-LA, for more focused paging.

Title: Substance pectique comme stabilisant de facteur de croissance
Inventor: YATES KENNETH M
IPC: A61K47/00
Filed: 1999-05-20
Abstract: La présente invention concerne une substance pectique provenant d'Aloe vera ainsi que d'autres sources, utilisée comme stabilisant et comme support d'administration de protéines interagissant par liaison avec une pectine ou une héparine, telles que des facteurs de croissance. La pectine d'Aloe, une pectine naturelle à faible teneur en groupe méthoxyle (LM) se lie à des facteurs de croissance interagissant par liaisons avec une pectine ou une héparine, par exemple, les FGFb, FGFa, et KGF de la famille des facteurs de croissance (FGF) des fibroblastes et le TGF-.beta.1 de la famille des facteurs de croissance .beta. (TGF-.beta.). Des tests avec des pectines d'agrumes LM ou HM (à forte teneur en groupe méthoxyle) ne montrent aucun effet liant avec le FGFb. Un faible effet de liaison au FGFb a été observé avec une pectine d'agrumes partiellement désestérifiée (acide polygalacturonique). La liaison protège le facteur de croissance de la digestion par une protéase. Les billes de gel de calcium préparées à partir de pectine d'Aloe se lient aussi aux facteurs de croissance qui interagissent par liaison avec une pectine ou une héparine. On peut aussi encapsuler le facteur de croissance dans le gel de calcium d'une pectine et dans le gel de sodium de pectine d'Aloe. Un facteur de croissance qui interagit par liaison avec une pectine ou une héparine et qui est stabilisé à l'aide d'une pectine est utilisé en cicatrisation. Une matrice contenant de la pectine est utilisée afin d'isoler une protéine interagissant par liaison avec une pectine ou une héparine.

Title: Amphibious vehicle having an inflatable pontoon
Inventor: REDMAN DONALD R
IPC: B60F3/00
Filed: 2001-07-27
Abstract: An amphibious vehicle having inflatable pontoons disposed in recesses formed in the vehicle body. The inflatable pontoons retract into the recesses when deflated to reduce the overall width of the vehicle to below the maximum allowable width for a road vehicle. The inflatable pontoons extend when inflated to beyond the maximum allowable width for road vehicles, thereby improving the stability of the vehicle when it is operated in water. The inside surfaces of the recesses provide support for transferring the uplift force generated by the pontoons to the vehicle body when in water. An elastic member may be used to retract the deflated pontoons into the recess. Decorative doors covering the recesses are forced open by the inflating pontoons to a position above the water line.

Abstract: Cost-effective processes and tools used therein are described that decontaminate sludge using remedial water in a closed and environmentally friendly system. Typical contaminants such as toxic metals, microorganisms, and toxic compounds are detoxified or destroyed by one or more remedial water treatments to sludge that is confined to the closed system. The closed system may comprise a covered rail road car, ISO container (40), or other large space into which the remedial water, and optionally, remedial gas, is applied by injection or other means. In a preferred embodiment, water is electrochemically activated at the site of use and injected through an array of pipes (10) within the container (40). A large variety of other waters and combinations of water, and even air treatments are particularly useful in combination with the closed system for treating sludge. Sludges such as dredged material, human or animal waste, and soils or sediments, are particularly amenable to conversion by the materials and methods of the invention into a more beneficial end use product.
