Patent EP-0479896-A1 (EP)
Inventor: FAIRBANKS JOHN P
IPC: G02F1/133
Filed: 1990-06-29
Abstract: Structure et procédé de commande d'un affichage à cristaux liquides tirant avantage du changement de réflectance important par rapport à un petit changement de tension pour de nouveaux matériaux d'affichage à cristaux liquides, en appliquant des tensions de pixels ON et OFF très proches de la tension de transition du matériaux à cristaux liquides et en régulant la tension appliquée pour qu'elle reste fiablement proche et du côté désiré de cette tension de transition. De même, une tension à courant continu de zéro net sur les pixels du cristal est maintenue en utilisant un mode de commutation proche de la moitié de la fréquence des modes de l'art antérieur. Des tensions d'attaque sont fournies à l'aide d'un régulateur de commutation plutôt qu'à l'aide d'un diviseur de tension comme dans l'art antérieur, ce qui se traduit par une réduction importante de la puissance d'alimentation électrique de fonctionnement. Le régulateur de commutation préféré génère uniquement trois tensions additionnelles pour l'alimentation des rangées et des colonnes de l'affichage, en comparaison aux cinq tensions générées du diviseur de tension de l'art antérieur. Un régulateur de tension on/off fournit ou ne fournit pas de manière alternative un courant électrique à une bobine principale (P81) commandant ainsi la tension sur les condensateurs (C81, C82, C83, C84) associés aux bobines secondaires (S81, S82, S83, S84). Ceci permet d'obtenir une commande de tension précise sur une plage étendue de charges d'affichage. Ce régulateur de tension est commandé de préférence par la basse tension appliquée sur les pixels pendant le temps durant lequel les pixels ne sont pas dans la rangée sélectionnée, c'est-à-dire pendant le temps où l'état logique d'un pixel n'est pas donné au pixel.

Title: Produits a base de kiwis
Inventor: JOHNSON ROBERT LEONARD
IPC: A23L19/00
Filed: 1990-09-07
Abstract: L'invention se rapporte à un procédé de préparation de produits à base de kiwis dans lequel les fruits sont réduits en pulpe et sont ensuite traités de façon à produire un certain nombre de fractions avec leurs composants. Ces fractions se composent d'une fraction contenant la chlorophylle, d'une fraction juteuse et d'une fraction de pulpe résiduelle. La fraction juteuse peut être extraite pour produire une fraction contenant l'arôme et une fraction juteuse exempte d'arôme et exempte de chlorophylle. La fraction de pulpe résiduelle est soumise à un traitement conservateur, par exemple par pasteurisation et séchage. On peut ensuite obtenir des produits à base de kiwis en combinant la fraction contenant la chlorophylle avec, selon les besoins, la fraction juteuse et/ou la fraction de pulpe résiduelle. La fraction contenant l'arôme et la fraction exempte d'arôme peuvent être utilisées à la place de la fraction juteuse. Ces produits à base de kiwis peuvent être incorporés dans des produits alimentaires de transformation tels que crèmes glacées, sorbets et boissons à base de jus de fruit.

IPC: B05B1/30
Filed: 1990-09-10
Abstract: A device and method, especially adapted for operating sprinklers, shower heads etc. at low flow, converts low continuous liquid flow to a high intermittent and pulsating flow. The liquid is introduced at a controlled low rate of flow, such as by the use of a pressure-compensated dripper in a liquid supply line. The liquid then flows into a chamber which is somewhat expandable in volume. The pressure increases in the chamber while outflow of the liquid is restricted until pressure created by introduction of the liquid is sufficient to eject the fluid intermittently at a higher flow. This is achieved by utilizing a pressure-responsive valve in the liquid exit of the container. The valve has a preset pressure response designed for quick response to create a water hammer effect. The valve has openings which create a pumping effect to admix air or another liquid with the effluent stream. Sprinklers, shower heads, or any other spraying devices connected to this pulsator will spray liquids to a large designated area with only a very small fluid flow. A drip line connected to such a device may have very large openings, yet the flow through each such dripper can be very large. A preferred form of the pulsator is a pulsating valve in which the receptacle container and the other required elements for such a pulsating device are part of the valve itself.

Abstract: Ether is produced from isoolefins having four to five carbon atoms per molecule, a monohydroxy alcohol having from one to five carbon atoms per molecule and a recycle stream comprising unreacted alcohol and water by passing the stream passed through a etherification zone to produce the desired effluent stream, separating the effluent stream into an ether product and an aqueous product containing unreacted alcohol and recycling a portion of the aqueous product to the etherification zone. Distillation is employed to separate the effluent from the etherification zone into a bottoms product stream, comprising the product ether, a distillate product comprising other hydrocarbons contained in the feed and the above-mentioned aqueous recycle stream. When producing ethyl-tertiary-butyl ether (ETBE), azeotropic grade ethanol, i.e., about 5 vol.% water, is preferably utilized. The utilization of the alcohol/water recycle stream can obviate the need for additional alcohol recovery from the distillate product.

Abstract: A burner control system for an intermittent pilot burner system uses a single pole double throw relay to control first and second electromagnetic valves [25,29] respectively supplying fuel for both burners [42,45] and for the main burner [45] only. The normally open contact pair [17,18] supplies the current for the first [29] and the normally closed contact pair [16,17] supplies the current for the second valve [25]. By selecting the valve supplying fuel for both burners to be of the type which has an appreciably higher pull-in current than drop-out current, and by shunting the relay's normally open contacts with a properly selected resistor [20], only a single relay is necessary. This resistor [20] is selected to supply current sufficient to hold the valve [29] open (current greater than the drop-out value) after the valve has received pull-in current through the closing of these normally open contacts [17,18], but insufficient to open the valve. Use of a single relay reduces cost, size, and power, and increases safety of the control system.
