Patent EP-0005913-A1 (EP)
Inventor: COGSWELL FREDERICK NEIL
IPC: B29C48/08
Filed: 1979-05-04
Abstract: A method of improving the processability of rigid polymers, particularly of unprocessable rigid polymers, wherein the rigid polymer in melt or solution form is subjected to an apparent shear rate between relatively moving surfaces of at least 100 sec -1 , particularly between 100 to 1000 sec -1 . The method reduces the viscosity of the melt or solution and when the melt or solution is fabricated into shaped articles whilst the viscosity is so reduced the shaped articles have improved properties, particularly more uniform orientation when compared with products prepared by methods which do not include the pre-shearing step prior to fabrication.

Abstract: Methode et appareil de reglage isoelectrique des fluides. Selon la methode de l'invention, le debit du fluide a traiter est etabli dans une premiere direction. Ce debit de fluide est profile a l'aide d'une pluralite de membranes microporeuses permeables (52-60) qui definissent des canaux paralleles orientes dans la premiere direction. Une tension electrique est appliquee sur les canaux profiles de fluide en ecoulement, et le reglage isoelectrique des fluides est effectue pendant leur debit, les membranes permettant entre elles l'echange des composants des fluides tout en produisant le profilage desire. On obtient une approximation du debit du type "bouchon" dans les canaux profiles. c'est-a-dire un debit ayant des caracte de section de passage approximativement uniforme. Dans le mode preferentiel de la methode selon l'invention, un passage de recirculation est etabli pour chacun des canaux profiles, de sorte que le fluide sortant de chaque canal est remis en circulation au debut du canal. De preference, ceci est effectue par pompage (400) des fluides dans chacun des passages de recirculation et par refroidissement (300) des fluides pendant leur recirculation. De cette maniere, un nombre de "passes" sont effectuees pour obtenir le degre voulu de reglage isoelectrique. Le refroidissement, qui a lieu pendant la recirculation, sert a reduire au minimum les problemes de dissipation de la chaleur par effet Joule pendant le reglage isoelectrique des fluides dans les canaux profiles. Egalement, dans le mode d'execution prefe de l'invention, la premiere direction est vers le bas de sorte que les fluides s'ecoulent sous l'influence de la pesanteur, pour permettre l'equilibre de gravite des niveaux du fluide dans les canaux a travers les membranes (52-60).

Abstract: Zum Ätzen wird das Silicium einem Plasma ausgesetzt, zu dessen Erzeugung von einer Gasmischung ausgegangen wird, welcne SF6, Cl2 und ein Inertgas enthält. Mit dem Verfahren läßt sich ein- und polykristallines Silicium in Gegenwart von in der Halbleitertechnik gängigen Materialien selektiv ätzen. Die Selektivität ist insbesondere in der Gegenwart von SiO2 und Si3N4, welche als Masken- und Isoliermaterialien wichtig sind, sehr gut. Wird das Silicium mittels reaktiven Ionenätzens entfernt, läßt es sich nicht nur selektiv in Gegenwart anderer Materialien, wobei das Si/SiO2- und das Si/Si3N4-Ätzgeschwindigkeitenverhältnis bei >30:1 bzw. >24:1 liegen, sondern auch gerichtet ätzen, so daß die erzeugten Vertiefungen senkrechte Seitenwände haben und die Ätzmaske über den Rand der geätzten Vertiefungen nicht hinausragt. Das Verfahren ist einsetzbar bei der Herstellung sehr hoch integrierter Schaltungen mit sehr kleinen bzw. schmalen und nane beieinanderliegenden Komponenten.

Abstract: The incorporation of intercalated carbon/graphite in any of its forms such as powder, flake or fiber into an organic matrix results in a high strength, light weight composite with an electrical conductivity considerably higher than a similar product made with nonintercalated graphite. A great variety of organic polymers may be used, such as epoxy, thermoplastics and thermoset resins. Depending on the form of the intercalated graphite, fabrication techniques of extrusion, lay-up, injection molding and pressing can be employed to fabricate the parts from these composites. A wide spectrum of properties is available from this type of composite in terms of strength and conductivity which will be useful for such widely ranging applications as aircraft structures and shielding for electronic equipment.

Abstract: The invention relates to a method and apparatus for removing slags by vacuum suction. In order to avoid dipping of a suction head (4) into the slag an upward force is always applied which is greater than the force with which the suction head (4) is attracted downward under the influence of the weight of its own and connected parts (5, 6). During normal operation, a drive force is applied through a separate drive system (23, 24, 29, 30) to keep balance with the upward force, thus keeping the suction head (4) in the desired position. When the drive force becomes inapplicable, the upward force holds the suction head (4) in the hazard-free raised position.
