Inventor: MCMURTRY DAVID ROBERTS TABERNA
IPC: G01B21/20
Filed: 1989-12-16
Abstract: On décrit un procédé permettant de balayer la surface d'une pièce d'usinage, dans lequel l'appareil portant la tête balayeuse se déplace le long d'une trajectoire, à vitesse constante de préférence, tandis qu'un dispositif de contact avec la surface, mû par la tête balayeuse, oscille transversalement à la trajectoire instantanée pour balayer une zone de ladite surface. Des transducteurs montés sur l'appareil, la tête, et si nécessaire sur le dispositif de contact avec la surface, fournissent des données concernant les positions dudit dispositif de contact avec la surface à une unité de collecte des informations sous commande d'un ordinateur. On décrit également un appareil pour réaliser ledit procédé, comprenant une tête balayeuse faisant osciller le dispositif de contact avec la surface, qui peut être un palpeur ou une sonde, par rapport à un axe unique, et de préférence à des axes orthogonaux. La tête peut comprendre un dispositif pour équilibrer par inertie la tête et pour équilibrer massiquement le dispositif de contact avec la surface, et des coussinets d'air qui supportent l'oscillation du palpeur ou de la sonde. Les surfaces à balayer peuvent être des plaques planes, des cônes, des alésages ou d'autres surfaces à angles combinés.

Filed: 1990-10-19
Abstract: L'invention se rapporte à un procédé de frittage de matériaux céramiques thermiquement instables (généralement non oxyde) par chauffage aux micro-ondes. Dans ce procédé, un corps du matériaux céramique est au moins partiellement entouré d'un lit protecteur de matériau particulaire, puis le corps et le lit (34) sont soumis à un rayonnement de micro-ondes destiné à assurer le chauffage et le frittage du corps. Pour permettre la réalisation du procédé dans un gaz contenant de l'oxygène, tel que de l'air, et à basse pression, le lit contient des quantités efficaces de: (A) un absorbeur de micro-ondes, lorsque le matériau céramique instable ne l'est pas déjà; (b) un matériau protecteur capable de produire une atmosphère localisée qui réduit la décomposition et/ou l'oxydation du matériau céramique instable; (c) un getter d'oxygène; et (d) un matériau de conductivité thermique suffisamment bonne pour empêcher un chauffage localisé excessif dans le lit. Ce procédé peut être combiné avec une étape de pressage isostatique à chaud effectuée simultanément ou ultérieurement. L'invention se rapporte égallement au lit de matériau particulaire utilisé dans le procédé et à un procédé permettant d'assembler des corps de matériau céramique instable par rayonnement de micro-ondes en utilisant le lit protecteur.

Abstract: The decontamination process described relates in particular to oil mixtures, water mixtures and acid mixtures, such as occur in the conversion of sewage sludge and/or industrial sludge, household refuse and/or other matter having organic contents. In this case, valuable materials - according to occurrence and requirement - are extracted from the polluted material streams and the pollutants are separated off and destroyed by thermal afterburning. High temperature corrosion zones are avoided during this by cooling, the individual process steps for extraction of valuable materials, destruction of pollutants and purification of the polluted matter streams and also the individual matter streams being combined according to occurrence and requirement. In addition, liquids/gases foreign to the process having a polluting character, such as for example landfill seepage waters and/or concentrates thereof and also landfill gases can be specifically purified in a stepped manner.

Abstract: A safety catch mechanism is provided which allows limited opening of a cupboard, drawer, or other storage unit. When the catch is engaged, a child cannot gain access to the contents of the storage unit, but an adult can release the safety mechanism when it is in its partially open position thus disengaging the catch and gaining access. The safety catch of the invention includes resilient engagement means (18,118) designed to retract to a non-protruding position relative to the storage unit portion on which it is mounted when it is released from engagement. The absence of protruding hooks or spikes when the storage unit is open enhances the safety of the catch mechanism.
