Patent CA-2148356-C (CA)
Title: Etablissement de trajets de telecommunication dans les reseaux de communication a large bande
Inventor: HILLER THOMAS LLOYD
IPC: H04L49/111
Filed: 1993-03-18
Granted: 2000-06-20
Abstract: Le procédé selon l'invention consiste à convertir des trains de signaux de modulation par impulsions et codage (PCM) en cellules de mode de transfert asynchrone (ATM) afin d'assurer la commutation et la transmission dans un réseau de télécommunications. Chaque cellule transporte un échantillon PCM comprenant jusqu'à 48 connexions téléphoniques différentes, ces dernières étant sélectionnées parmi les trains de données PCM parce qu'elles ont une destination commune. Les cellules sont transmises par des circuits virtuels ATM à raison d'une cellule toutes les 125 mus. L'avantage de ce système est que les systèmes de transmission ATM sont reliés aux systèmes PCM sans que cela occasionne des retards considérables et sans qu'il soit nécessaire de recourir à un tamponnage supplémentaire. De plus, on peut, en principe, établir de nouveaux trajets téléphoniques en utilisant les intervalles de temps disponibles dans les cellules des trajets virtuels existants. On peut également utiliser cette invention pour mettre en place un système de commutation de grande capacité ou une grappe de systèmes hautement interconnectés plus petits.

Title: Hydrophilic polyurethanes
Inventor: FISCHER HERBERT
IPC: C09J7/38
Filed: 1993-12-14
Granted: 2005-10-11
Abstract: Described are hydrophilic non-ionic water-soluble high-molecular polyurethanes with a specific viscosity of at least 0.4 (measured on a 1 % aqueous solution at 20 °C). The polyurethanes can be produced essentially from polyethylene glycol and a diisocyanate at 80 to 200 °C without using a catalyst or solvent. They can be used as a basis for adhesives, in particular fusion and solvent adhesives, to bond e.g. wall-paper and labels. They can also be used as stabilizers in emulsion polymerization and as viscosity-increasing agents in aqueous systems.

Abstract: Divulgation d'un procédé pour convertir le sulfure d'hydrogène, contenu dans un circuit d'alimentation en gaz, en soufre élémentaire et en hydrogène. Ce procédé consiste à : mettre en contact le circuit d'alimentation en gaz avec un solvant organique polaire ayant en solution une anthraquinone et, facultativement, un agent complexant; faire réagir le sulfure d'hydrogène gazeux et l'anthraquinone de manière à produire du soufre et une anthrahydroquinone en solution; et de déshydrogéner catalytiquement l'anthrahydroquinone afin de produire de l'hydrogène et de l'anthraquinone. Selon cette invention, on ajoute une quantité relativement faible d'eau au solvant organique polaire, permettant ainsi d'augmenter les quantités de soufre élémentaire précipitées puis récupérées. L'addition d'eau avant ou au cours de la production de soufre accroît la quantité d'hydrogène produite sélectivement au cours de la déshydrogénation ultérieure de l'anthrahydroquinone.

Abstract: The present invention provides a process for the manu-facture of a product essentially containing amylose from vegetable materials, in particular from peas. To this end, the flour is mixed with an alkaline decomposing agent, and then a separation into a liquid protein phase and a solid phase containing polysaccharide is performed. The solid phase is then re-suspended and subjected to several sifting steps, followed by at least one washing step and subse-quently a drying step. From such polysaccharide material, in particular from amylose, any kind of moisture-resistent, flexible, and in particular biodegradable articles can be procuded by means of conventional plastics technologies, in particular the injection molding technique. A particular advantage of the present invention resides in the fact that the thermoplastic polysaccharide material, which is pro-duced from renewable raw materials, can also be processed into sheets which in turn can then be worked with conven-tional plastics techniques.

Title: A solubilized hop extract for imparting hoppy aroma and flavor to beer
Inventor: GUZINSKI JAMES A
IPC: C12C3/08
Filed: 1995-09-07
Granted: 2003-11-18
Abstract: A solubilized water-dispersible lipidic hop extract composition, consisting of hop aroma and flavor components and comprising at least 10% by weight of free fatty acid flavor and aroma substances derived from hops, is useful to increase the utilization of the hop aroma and flavor compo-nents. It may be produced by treatment of an extract of hops with an excess of alkali.  The starting hop extract, made conventionally as by extraction with organic solvent or supercritical carbon dioxide,  preferably has alpha, isoalpha, and beta hop acids removed before treatment with excess alkali.   A cosolvent,  such as a lower alkanol, polyol, or wetting agent, heat, or high shear may be used to improve mixing of the lipidic organic phase of the hop extract with the excess alkali.   The solubilized water-dispersible lipidic hop extract imparts an enhanced hop aroma and flavor upon addition to the wort at some point during the brewing process between boiling and the begin-ning of fermentation.  A beer incorporating the solubilized lipidic hop extract has a stronger hop aroma and flavor than  beer  incorporating  the  usual  unsolubilized  hop extract.

Abstract: The method for preventing monitoring of postage indicia data which is sent from a postage metering vault to a remotely located digital printer over a communication link between the meter vault and the digital printer. The meter is provided with an encryption engine for encrypting postage indicia data utilizing a encryption key. The digital printer includes a decryption engine for decrypting postage data received from said meter utilizing the same encryption key and then prints a postage indicia pursuant to the decrypted postage indicia data. The postage meter also includes a key manager for generating new encryption key pursuant to a token which is either randomly generated or generated pursuant to an algorithm by a similar encryption key manager located in the digital printer which token is also used to generate the decryption key for the decryption engine. As a result, the encryption keys are the same. Upon power-up of the system or at such other preselected times, the print controller module of the digital printer sends out an encrypted message to the meter. The message consist of a random number. The encryption/decryption engine of the vault decrypts the message. The vault then returns an encrypted new message to the print controller which includes an encoded representation of the relationship of the two messages. Upon receiving the new message from the vault, the print controller decrypts the new message and verifies the relationship. The print controller is then enabled to print a postage indicia.

Abstract: A sweater or similar knitwear product is disclosed, mainly consisting of a knitwear fabric of the yarn used for the so-called cowboy or denim cloth, viz. the very wear resistant, indigo dyed cotton yarn.  Such a sweater will be softer than the denim cloth, but it is desirable that both a collar and the button-bands, i.e. the front side portions holding the closing system, be made of a more rigid material. Advantageously, this material may consist of the woven denim cloth.  The knitted fabric will shrink considerably in the wash, and it is complicated to stitch-on the woven fabric so as to avoid future wrinkling.  According to the invention the knitwear parts for the products are knitted as fully fashioned pieces with pronounced loose knitting, and these pieces are subjected to a washing and drying treatment, whereby that shrink to a desirable size and density, and only thereafter the woven pieces are attached by stitching.  This stitching may now be effected fully conventionally, as the said wrinkling will automatically be avoided.
