Title: Apparatus and method for converting organic material into fuel
IPC: C10J3/58
Filed: 1980-03-06
Granted: 1982-12-22
Abstract: Organic material is heated in a pyrolytic reactor 15 in which an initial charge of charcoal is located, thereby driving off volatiles from the organic material while leaving charcoal (char) behind. The volatiles are then passed over a base material which is at a temperature substantially above the pyrolizing temperature which causes a chemical reaction of the tars and volatiles, resulting in an output of a gaseous mixture consisting largely of carbon monoxide and hydrogen, characterized by an absence of tars. The reactor 15 is arranged to permit a continuous flow of organic material volatiles, and char through it, resulting in continual replenishment of organic material in its pyrolizing portion, and replenishment of the charcoal bed portion by the char produced from the pyrolysis reaction.

Abstract: Living, fermentable yeast cells are prepared having an enzyme or mixture of enzymes coupled thereto. Enzyme coupling is carried out by contacting at least partially dehydrated living yeast cells with an aqueous enzyme solution to cause the yeast cells to rehydrate and a layer of enzyme to form on the surface of the yeast cells, and than contacting the rehydrated yeast cells with an enzyme-precipitating solution which optionally contains a cross-linking agent to cause the enzyme to become attached to the yeast cells. An aqueous solution of tannin is preferably the enzyme-precipitating solution and gluardialdehyde is preferably the cross-linking agent. Pepsin coupled to Saccharomyces yeast, when used to ferment grape must to produce wine, results in practically foam-free attenuation, quicker fermentation and better self-clarification. Saccharomyces yeast having amgloglucosidase coupled thereto may be used to ferment beer wort to produce a diet beer.

Abstract: The invention relates to a switch device (10) which is actuated when a preselected fluid pressure differential is exceeded. A piston (52) exposed to the pressure differential carries a plunger (56) which contacts a lever arm (64) mounted on a shaft (60). A spring (82) normally prevents the shaft (60) from turning but is overcome when an excessive pressure differential is applied across the piston (52). A switch arm (96) mounted on the shaft (60) actuates the switch (104) in response to turning of the shaft (60).

Title: Procede et appareil de commande d'un moteur a induction a courant alternatif

Granted: 1984-10-10
Abstract: Procede et appareil de commande d'un moteur a induction a courant alternatif ayant au moins deux phases. Le moteur est commande suivant une maniere connue par deux signaux d'entree S1, S2, qui sont connectes a un dispositif de resolution (1), dont les signaux de sortie sont utilises pour produire des signaux separes d'alimentation vers les phases du moteur. Un signal mesure U, representant la vitesse de rotation du moteur est renvoye au systeme de commande et est utilise pour calculer la frequence d'oscillation de l'oscillateur (5), qui entraine le dispositif de resolution. Un circuit de calcul calcule la frequence d'oscillation sous la forme de la somme du premier signal de commande S1 multiplie par un premier facteur constant et le signal de tachymetre U multiplie par un second facteur constant. D'apres ce procede de commande, la frequence de l'oscillateur augmente en meme temps que l'on a un signal de commande S1 croissant et un signal de tachymetre U croissant, mais decroit avec une charge du moteur croissante parce que la vitesse du moteur diminue. Ce reglage automatique de la frequence se traduit par une amplitude constante du champ magnetique du stator a toutes les vitesses du moteur et avec toutes les differentes charges.

Granted: 1987-04-08
Abstract: A process for separating large percentages of aggressive gases such as carbon dioxide from low temperature gas mixtures wherein the gas mixture is passed through a plurality of treatment zones in series. In each treatment zone the gas mixture is first compressed to a pressure such thatthe partial pressure of the carbon dioxide is not greater than the critical carbon dioxide partial pressure and the compressed gas mixture is then brought into contact with a membrane more permeable to carbon dioxide than other gases of the mixture such that carbon dioxide permeates the membrane to the other side thereof. The gas mixture is maintained in contact with the membrane a sufficient time to tower the partial pressure of the carbon dioxide in the non-permeated gas mixture to less than about 40 percent of said critical carbon dioxide partial pressure. The process is especially useful for separating carbon dioxide from methane and other gases.

Abstract: Des polymères d'éthylène amorphe chlorés présentant des tendances relativement peu prononcées à la formation de blocs en l'absence d'additifs empêchant la formation de blocs sont préparés par un procédé multi-étapes. Le procédé consiste à faire réagir des particules de polyéthylène poreuses, solides, finement divisées et à densité élevée avec du chlore à l'état gazeux en présence d'un initiateur à radical libre, pendant que ces particules sont agitées ou maintenues dans un état de lit fluidifié. Dans une première étape, l'addition de chlore à l'état gazeux commence lorsque les particules agitées se trouvent à une température inférieure à 50oC. Pendant la première étape il n'y a pas de chloruration, ou très peu. Pendant une deuxième étape, les particules agitées sont chlorées jusqu'à un niveau compris entre 5 et 14 % environ, tandis que la température de ces particules est augmentée jusqu'à ateindre un niveau compris entre 50oC et 105oC environ. La chloruration des particules agitées se poursuit pendant une troisième étape où la température de ces particules est augmentée à une vitesse prédéterminée jusqu'à une valeur comprise entre 125oC et 132oC environ. La chloruration des particules agitées est complétée pendant une quatrième étape où la température des particules est augmentée jusqu'à une valeur dépassant 130oC environ, tout en restant inférieure à la température à laquelle les particules ont tendance à s'agglomérer. La quatrième étape se poursuit jusqu'à ce que l'on obtienne un taux de cristallinité relative résiduelle inférieur à 2 % environ et jusqu'à ce que l'on atteigne la teneur en chlore désirée. Des valeurs de la teneur en chlore citées à titre d'exemple sont comprises entre 30 et 42 % en poids environ du polymère chloruré.

Abstract: A safety device for use in a combustor detects incomplete combustion and suspends the combustion. The safety device employs a sensor (25) of an oxygen concentration cell type which is made of, for example, zirconia. The safety device is arranged such that no voltage is applied to the sensor (25) during ignition, and the ignition is effected with a low air-fuel ratio. Thus, when compared with a conventional safety device wherein a voltage is applied to the sensor (25), the safety device of the invention has a simplified construction and a lower production cost, and enables a reliable ignition detection. After ignition, combustion at a normal air-fuel ratio is restored and a voltage is applied to the sensor (25), so that misfiring can be reliably detected.
