Patent CA-2262738-A1 (CA)
Title: Transition metallohalopolymers
Inventor: VARGO TERRENCE G
IPC: C08F14/16
Filed: 1997-08-06
Abstract: Novel metallohalopolymers comprising an oxyhalopolymer and a transition metal covalently bonded to an oxygen site on the oxyhalopolymer possess desirable properties of inertness, stability, hydrophobicity and high electronegativity like fluoropolymers such as PTFE. The metallohalopolymers also possess unusual superacidic properties making oxygen-containing sites on the polymeric backbone highly nucleophilic and reactive with transition metals for synthesis of stable metallized polymers without requiring exposure without requiring exposure to destructive calcining temperatures or intermediate chelating organosilane linking agents. The transition metals can be covalently bonded directly to the polymeric support to form metallohalopolymers for use as catalysts in the synthesis of chemicals, biocides and useful articles of manufacture, such as filtration devices containing the biocidally active metallohalopolymers.

Title: Polymeric compositions and methods for making construction materials from them
Inventor: SULLIVAN HENRY W
IPC: C08L23/02
Filed: 1997-08-11
Abstract: Polymeric composites are described that can be formed into articles of construction to replace similar articles formed of wood and concrete. The composites comprise a polymer component comprising polyolefins preferably obtained as waste or recycle; a rubbery polymeric component preferably obtained from disposed tires; and a reinforcing filler component comprising mica. The mica is preferably of the expanded variety to allow for a reduction in density over similar composites containing traditional mica. The evaporation of volatile compounds initially contained within the different components, primarily the rubbery polymeric component, allows for the production of articles of construction having a foamed inner core in which the foamed cell structure has not been achieved through the use of traditional CO2 generating foaming agents. Processes for forming the articles of construction are provided that include both extrusion and molding techniques.

Abstract: Dans un outil servant à ramasser les excréments de chiens, l'élément essentiel est jusqu'a présent, à notre connaissance: une simple pelle, la main munie d'un papier ou d'un sac en plastique, divers systèmes de griffes, de raclettes ou de raclettes-sac. Certains peuvent ne ramasser que partiellement et, pas sur tous les terrains. Dans l'invention de notre nouveau système: RAMASSEUR D'EXCREMENTS DE CHIENS, la pelle en carton biodégradable ou non, ou en tout autre matériel à base de cellulose ou plastique qui répond aux conditions requises, mince et rigide, aux formes et mésures étudiées, permet de ramasser d'une façon complète et sur tous les terrains. Le sac en plastique, biodégradable ou non, plus large et plus long que la pelle, et dans lequel on glisse la main qui opére la pelle, permet le ramassage d'une manière plus hygiènique. Le manche télescopique lèger, fait de plastique, et muni d'une pince pour assujettir la pelle, peut remplacer éventuellement la main, évitant ainsi de se baisser. Le petit format du manche, en fait son transport moins encombrant qu'un grand manche. Notre invention réside dans le fait d'avoir réuni deux outils dans un : la pelle et le sac. Transportable, opérable et jetable dans les meilleures conditions de commodité et hygiène.

Title: Method for preparing cleaved products from castor oil or derivatives thereof
Inventor: TOTAH THOMAS S
IPC: C07C45/27
Filed: 1998-02-11
Abstract: A process for producing a cleaved product from castor oil, or derrivatives thereof, by high temperature caustic oxidation reaction accomplished by combining at least one chemically inert diluent, a catalyst, and an alkali in aqueous solution to form a first mixture wherein the diluent is present in an amount sufficient to reduce foaming and solidification of the mixture while increasing the yield and improving the purity and adding a ricinic compound to the first mixture to form a second mixture. The temperature of the second mixture is raised to a level sufficient to conduct pyrolysis, and the cleaved product produced thereby is recovered by adding an acid to the reaction mixture in an amount sufficient to acidify the reaction mixture down below a pH of about 6. The invention further relates to the reaction mixture used to produce the cleaved products. The present invention provides higher product yields and purer cleaved products produced by the oxidation of castor oil or its derivatives than conventionally obtained.

Filed: 1999-09-17
Abstract: An intermittent extension service that is a mechanism for temporarily adding a member to a multi-appearance directory number type of service (e.g., EKTS or MADN) without sacrificing security. Service subscription data identifies the subscriber as having ordered a specific number of simultaneous extensions. The number of extensions is then provisioned by appropriate network resources. Thereafter, whenever a subscriber wishes, they can activate an additional extension by causing it to register with the telephone network. Similarly, the subscriber can de-activate extensions located where it is known that there is no one present to answer the phone when it rings. Thus, the subscriber is given the ability to provision and manage the physical locations of clients for the number of extensions ordered from the service provider.
Patent CA-2285164-A1 (CA)
Title: A spread-spectrum transmission system with filtered multi-carrier modulation
Inventor: RICHARD JOEL
IPC: H04L27/26
Filed: 1999-10-07
Abstract: The invention provides a spread-spectrum transmission system with multiple carrier modulation in which the signals for transmission over each of the subcarriers are filtered prior to being transmitted over the subcarrier, thereby making it possible on reception to synchronize the various subcarriers in time, and in which each subcarrier carries a plurality of chips that result from spreading a single symbol. With coherent modulation, the number of chips resulting from spreading a single symbol and transmitted over each subcarrier is selected so as to enable the various subcarriers to be put into phase alignment by recombining the chips coming from the same symbol on each subcarrier. With differential modulation, the transmission over each subcarrier of chips resulting from spreading a single symbol provides resistance to jamming by limiting recombination losses because of the differential modulation.
