Patent CA-2220857-A1 (CA)
Inventor: ONGARO IVANO
IPC: A61K8/19
Filed: 1998-01-15
Abstract: The invention is a pastille consisting of coated chewable gum, which controls a chemical process for rendering teeth more resistant to tooth decay. The pastille has a coating which is soluble in the oral environment and releases fluoride ions while dissolving, and the body consisting of a flavoured chewable gum formulated in such a way as to be capable of releasing calcium ions. The fluoride ions, which are released as the coating of the pastille dissolves in the mouth, permeate the surfaces of the teeth. The mastication of the gum subsequently releases the calcium ions, from a variety of calcium salts mixed into the gum. The released calcium ions consequently react with the fluoride ions which were previously permeated into the teeth to form calcium fluoride precipitate, and other calcium-fluoride compounds in the teeth and on the surface of the teeth, which render the teeth more resistant to attack by bacterially produced acids. Thus making them more resistant to tooth decay.

Title: Alpha 1a adrenergic receptor antagonists
Inventor: NERENBERG JENNIE
IPC: A61K45/00
Filed: 1996-06-04
Abstract: This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective alpha 1a adrenergic receptor antagonists. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved.

Abstract: Procédé qui consiste à identifier les courbes de distribution de couple des lignes de charge réparties vers l'avant et vers l'arrière d'un train d'engrenages du système de transmission à lignes réparties et à transcrire les courbes de distribution de couple vers l'avant et vers l'arrière identifiées dans un format graphique, l'abscisse du graphique représentant le couple d'entrée (Tin) couplé dans ce train d'engrenages et l'ordonnée du graphique représentant le couple transmis respectivement par l'intermédiaire des lignes de charge réparties vers l'avant et vers l'arrière. Ledit procédé consiste en outre à choisir un point d'action prédéfini pour le système de transmission à lignes réparties, une répartition égale de couple entre les lignes de charge réparties vers l'avant et vers l'arrière du train d'engrenages étant désirée. Ensuite, les courbes de distribution de couple vers l'avant et vers l'arrière sont modifiées de manière analytique selon le besoin pour passer par le point de fonctionnement prédéfini. Finalement, la relation de temps des engrenages et pignons de la ligne de charge répartie représentée par la courbe de distribution de couple analytiquement modifiée ayant la pente la plus raide est modifiée pour fournir une différence de temps intentionnelle entre les engrenages et pignons des lignes de charge réparties vers l'avant et vers l'arrière, respectivement, du train d'engrenages de manière à ce que pendant le fonctionnement du système de transmission à lignes réparties, l'autre ligne de charge répartie transmette l'ensemble du couple d'entrée (Tin) à l'arbre principal de rotor sur toute la plage de couple d'entrée. Les étapes susmentionnées sont répétées pour chaque train d'engrenages restant du système de transmission à lignes réparties pour fournir une différence de temps intentionnelle entre les engrenages et pignons des lignes de charge réparties vers l'avant et vers l'arrière, respectivement de chaque train d'engrenages restant de manière à ce qu'une répartition égale du couple dans les lignes de charge réparties vers l'avant et vers l'arrière de chaque train d'engrenages restant soit obtenue au point de fonctionnement prédéfini.

IPC: C10G1/04

Abstract: A sand/liquid separator provides for the conditioning of oil sands. Clean sand is separated from the ore and discharged for use as backfill. The sand/liquid separator machine includes horizontal shafts with paddles that act on a fluidized bed. The overall height of the machine is increased over prior art devices so the water volume is expanded. For a given residence time, more sand can be separated out than is otherwise possible. The water-to-sand ratio is an independent variable, water is recycled independent of the sand. The rate of water recycle depends only on the heat input needed and the clay content of the feed. The rate of water input is limited by the rise velocity needed to separate sand larger than forty-four micron from the water/liquid phase. This, in turn, determines the maximum oil sand feed rate based on the total clay in the feed at up to six percent, by weight, of clay in the middlings in the machine. This optimizes the performance of the process to cope with all the variables of heat input, ratio of oil sand feed to water, and clay content of the feed.

Abstract: A system for creating multiple subchannels in a single two-way radio channel is described. Each subschannel (12-20) in the system is capable of carrying voice or data. Each subchannel is split into an upper (12u-20u) and a lower (121-12u) band with the upper band placed in a particular frequency range above the center of the channel and the lower band below the center of the channel. Either one or two pilot tones (24) placed at or adjacent to the center of the channel are used to provide a reference for all the subchannels to allow for correction of distortions when the signal is received. The system includes a base station with a transmitter and receiver and a plurality of mobile units each with a transmitter and receiver. The base station transmits a signal which is the sum of all the subchannels. The mobile unit receives the signal, separates and processes the particular subchannel for that mobile unit. The mobile unit transmits only the desired subchannel or subchannels with a pilot tone located adjacent to one of the bands of the subchannel. Two or more subchannels can be used in conjunction to achieve faster data rates of higher quality voice transmissions.

The method includes the steps of causing (6) a subscriber unit (20) to emit (70-72) a predetermined signal, which is thentransmitted along the link (26) to the exchange (30). The received signal (8) isanalysed (12) and a determination is made (10) regarding the quality of the telecommunications link (26) based on the received signal. More specifically, anassessment of an operational quality of the telecommunications link at relatively high broadband frequencies is based on the signal received at the exchange (30) when the predetermined test signal is one of a DTMF test signal transmitted within a relatively low audio frequency range and an accurately generated signal generated from a dongle (60) placed in-line between the subscriber unit (20) and the telecommunications link (26). In relation to the accurately generated signal generated from the dongle (60), it is preferable that the test signal has frequencies relatively close to and most preferably within afrequency band of a proposed broadband service.
