Title: Procede et dispositif pour la separation mecanique d'un systeme disperse
Inventor: SLOWIK GUNTER
IPC: B04C5/02
Filed: 1999-10-27
Abstract: L'invention concerne un procédé pour la séparation mécanique, dans un séparateur centrifuge, d'un système dispersé en deux ou plusieurs systèmes dispersés ayant des propriétés différentes, ainsi qu'un dispositif convenant à la réalisation du procédé. Partant des inconvénients liés à l'état connu de la technique, l'invention vise à créer un procédé du type en question permettant, sans modifications structurelles importantes, de faire varier de manière importante le degré de séparation indépendamment du débit de fluide et d'influer sur la maille et la précision de séparation. A cet effet, on partage les flux partiels (7, 8) en conduits d'alimentation (1, 2) se distinguant par la superficie de leur section au niveau des points d'entrée (S¿1?, S¿2?) dans le séparateur centrifuge. En cas de partage des flux partiels en plus de deux conduits d'alimentation tangentiels (1, 2, 12, 13), on calcule les superficies de section (2 et 13 ou 1 et 12) en additionnant les superficies des sections des conduits d'alimentation reliés au flux partiel correspondant (7 ou 8), les sommes des superficies des sections des flux partiels respectifs (7 ou 8) différant ainsi aux points d'entrée (S¿2?, S¿13? ou S¿1?, S¿12?) dans le séparateur centrifuge.

Title: Reduction of ozone in an enclosed environment
Inventor: MAXWELL STUART
IPC: A61L9/01
Filed: 2000-06-08
Abstract: In an enclosed environment subject to increased levels of ozone caused, for example by electrostatic equipment such as laser printers and photocopiers, the levels of ozone are reduced by releasing vapour from a terpenoid or a mixture of terpenoids into the environment at a controlled rate. In one aspect the vapour is released from an emission element of absorbent material impregnated with the or each terpenoid compound and located within a container which in use allows free circulation into the environment. The absorbent/emission characteristics of the absorbent material are selected to provide an extended release of the terpenoid or terpenoids into the environment.

Abstract: A Cam Hinge is a hinge mechanism that connects a Wing Framework to a horizontal Main Framework in a perpendicular orientation, and allows the Wing Framework to fold down and form a single close fitting platform in one plane. Such a hinge enables the Wing Framework to form a platform with the Main Framework in a shorter period of time than a conventional platform which must be manually assembled and leveled. The Wing Framework folds down to a horizontal position and is supported by a leg in contact with the ground on the outside edge of the Wing Framework. At this point the cam lever is unlocked and rotated approximately 190 degrees to the final position creating a close fitting platform in one plane.
