Patent CA-2173634-A1 (CA)
Inventor: GAUDREAULT PIERRE
IPC: A01G23/083
Filed: 1996-04-09
Abstract: La présente invention est une machine forestière conçu pour accomplir en un cycle continu plusieurs opérations successivement ou simultanément lors de la récolte des arbres en forêt. Le concept revendiqué est un véhicule tout-terrain monté sur pneus ou sur chenilles. Cet engin multifonctionnel innove par le concept de son outil d'abattage qui peut servir également de grappin de chargement de bois court, et par une table de façonnage qui peut être fixe ou tournante dans le plan horizontal par rapport au châssis porteur et cela de façon indépendante de la table tournante supportant les mâts et la tête d'abattage. L'outil d'abattage est fixée à l'extrémité d'un mât articulé qui est lui-même fixé sur une table tournante spécialement surélevée dans le but de placé sous cette structure tournante la table de façonnage multifonctionnelle. La table tournante supportant les mâts peut également être placée de côté par rapport à la table de façonnage. La table de façonnage peut effectuer les fonctions d'ébranchage, de tronçonnage, d'écimage, de mesurage des longueurs de troncs, d'empilage des troncs et du triage de ceux-ci dans un panier collecteur monté sur le côté de la table de façonnage parallèlement à l'axe d'ébranchage. Cette table multifonctionnelle est un concept innovateur par sa position dans l'ensemble machine, par sa capacité d'être orienté dans le plan horizontal de façon indépendante du châssis transporteur et de la table tournante qui porte les mâts et l'outil d'abattage, également par son système de mesurage des troncs en utilisant une butée mécanique pour garantir la précision des longueurs avant le tronçonnage, par un mécanisme d'éjection et d'empilement des troncs, et finalement par un système d'alimentation de la table de façonnage. Ce nouveau concept innove par son caractère respectueux de la ressource et de son environnement. Ainsi la nouvelle machine conservera un contrôle total sur l'arbre coupé et sur les billes tronçonnées ne les laissant jamais tomber sur le parterre de coupe pour éviter qu'ils écrasent les jeunes arbres et les repousses.

Each layer in the multiple layer structures can optionally be bonded together by the use of an adhesive or the layer (14, 18). The structures made from blends of the present invention have a clarity that is superior to structures previously known in the art.
Patent CA-2176866-A1 (CA)
Title: Strengthened public key protocol
Inventor: VANSTONE SCOTT A
IPC: H04L9/32
Filed: 1996-05-17
Abstract: A cryptosystem utilizes the properties of discrete logs in finite groups, either in a public key message exchange or in a key exchange and generation protocol.  If  the group selected has subgroups of relatively small order, the message may be exponentiated by a factor of the order of the group to place the message in a subgroup of relatively small order.  To inhibit such substitution, the base or generator of the cryptosystem is chosen to be a generator of a subgroup of prime order or a subgroup of an order having a number of relatively small divisors.  The   message may be exponentiated to each of the relatively small divisors and the result checked for the group identity. If the group identity is found, it indicates a vulnerability to substitution and is rejected.

Inventor: OZUM BAKI
IPC: C01C1/247
Filed: 1996-10-17
Abstract: This invention is based on the catalytic, high pressure - moderate temperature oxidation of hydrogen sulfide (H2S) to ammonium sulfate ((NH4)2SO4) in ammoniacal (NH3) solutions by using air or oxygen (O2) as the oxidant. The present invention has significant commercial potential for the utilization of H2S, which is an alternative to the existing Claus processes which oxidizes H2S to elemental sulfur (S). This invention is considered as an alternative to the Claus process. The present invention uses the inorganic or organic salts of the transition state elements as disposable or supported catalyst in homogeneous or heterogeneous phases. The present invention covers a wide range of reactor operating conditions such as temperature, pressure, catalyst type, catalyst support material, catalyst concentration, feed gas flow rate, feed gas composition, feed gas temperature, reactor geometry, reactor operating mode (reactor steps, parallel or counter flow, fixed bed, fluid bed, spouted bed, batch, semi-batch, continuous flow, radial flow, plug flow, axially mixed-axial flow, recycle, etc.) for the catalytic oxidation of H2S to (NH4)2SO4 in ammoniacal (NH3) solutions.
