Abstract: La présente invention est relative à un système et une méthode d'extraction d'énergie d'une source capacitive, par exemple l'énergie induite dans une section isolée d'un fil de garde d'une ligne de transport à tension CA.  L'énergie est extraite d'un fil de garde à l'aide d'un transformateur-abaisseur de tension auquel le primaire est relié et qui génère au secondaire une tension alternative dont la valeur est régularisée par commutation shunt. La commutation shunt proprement dite est effectuée à l'aide de thyristors de puissance dont la mise à feu est commandée de façon sélective suivant la phase et l'amplitude de la tension de sortie. Un comparateur est utilisé pour comparer la valeur de la tension de sortie avec celle d'un signal émis par un générateur de rampe interne.  En outre, l'instant de mise à feu des thyristors est commandé par le signal de sortie du comparateur et également suivant une information sur la polarité des alternances de la tension de sortie.  Ce système de régulation par commutation shunt permet de soutirer du fil de garde un maximum de puissance par kilomètre de fil isolé et assure une grande stabilité à la tension de sortie en dépit de variations extrêmes de la charge raccordée au secondaire du transformateur-abaisseur de tension.  Cc système d'extraction permet entre autre de fournir économiquement une alimentation, continue, aux postes répéteurs d'un réseau microondes qui longe habituellement les lignes de transport d'énergie en des lieux éloignés.

Abstract: Abstract of the Disclosure The novel tetradecapeptide   is described along with corresponding non-toxic pharma-ceutically-acceptable acid addition salts as well as inter-mediates useful in the synthesis of the tetradecapeptide.   This tetradecapeptide is prepared by reacting the cor-responding straight-chain tetradecapeptide with an oxidizing agent to convert the two sulfhydryl groups to a disulfide bridge.  This tetradecapeptide as well as its pharmaceutical-ly-acceptable acid addition salts exhibit various activities including inhibition of the release of gastric acid and reduction of gut motility.

Abstract: ABSTRACT                   Carbonyl-containing organic impurities are removed from organic hydrocarbons produced in conventional facilities.  The process comprises contacting the hydrocarbon product with an aqueous solution containing a water soluble reducing agent in slightly greater amount than is theoretically required for complete reaction with the carbonyl compounds, in an in-line mixing means, and then passing the mixture to a phase separator to separate the layers.  The resulting "scrubbed" hydrocarbon product is substantially purified (e.g., to as low as less than 2 ppm carbonyl compounds).  An optional second mixer and scrubbing tower are provided as a back-up system in case of surge conditions or maintenance of the first system.

Abstract: TITLE          HEAT STORAGE DEVICE          ABSTRACT OF THE DISCLOSURE         A heat storing fireplace including a fire-box sur-rounded by a heat storage medium which is either an enclosure containing a material having a high specific heat such as sand or gravel or a large number of heat conducting bags con-taining a high specific heat material.  Exhaust gases are conveyed from the fire-box to an exhaust outlet by several conduits extending through the heat storage medium in a cir-cuitous path in order to transfer heat from the exhaust gases to the heat storage medium.  Heat is further distributed through the storage material by a heat conducting lattice fastened to the conduits and extending through the storage medium in a circuitous path.  Combustion air enters the bot-tom of the fire box through a combustion air inlet jacket surrounding the exhaust outlet in order to simultaneously pre-warm the combustion air while thermally insulating the exhaust outlet from its support structure.  A draft is crea-ted through the fire-box by an exhaust fan mounted in the exhaust outlet.  Although the heat storage medium is primar-ily heated by burning fuel in the fire-box, it may also be heated by either an electric grill or solar heat exchanger embedded in the heat storage medium.  The upper portion of the storage medium is covered by a ventilating plenum which allows heat to escape from the enclosure.  The plenum has a pair of ventilated sidewalls separated from each other by a baffle.  A fan, which may be thermostatical1y controlled, is positioned in an opening in the baffle in order to selective-ly produce air flow through the plenum.  Heat in the storage medium may also be utilized by placing a hot water heating heat exchanger in the storage medium.

One em-bodiment includes a device which senses the difference in pressure between the pipeline and the monitor chamber and delivers a signal when that difference becomes excessive.  In another em-bodiment, a liquid reservoir at atmospheric pressure is connected to fill the monitor chamber on the other side of the diaphragm, so that the liquid pressure in the monitor chamber is proportionate to the rate of change of pressure in the pipeline and, when this pressure becomes excessive, an energizing signal is generated to relieve the surge.
