IPC: A47K3/00
Filed: 2000-07-14
Abstract: L'invention concerne un circuit de régulation utilisé dans un système de cuve à remous, comprenant un capteur de pression (70) qui produit un signal représentatif de la pression dans le système. Un microcontrôleur (68) est couplé de façon à recevoir le signal du capteur, et est configuré de façon à stocker un premier niveau de pression. Un microprocesseur compare ce premier niveau de pression avec le niveau de pression mesuré ultérieurement, et produit un signal de commande si la comparaison indique un changement de pression qui dépasse une quantité prédéterminée. Un commutateur (54) électronique est couplé de façon à recevoir le signal de commande du microcontrôleur, et à couper l'alimentation électrique de la pompe en réponse celui-ci.

Title: An apparatus and process for inducing magnetism in a flow stream of particulate matter
Inventor: MINER ROBERT
IPC: B03C1/027
Filed: 2002-02-15
Abstract: The present invention provides an apparatus for inducing magnetism in a flowstream of an at least partially magnetisable particulate feed material suspended in a liquid, the apparatus including: a treatment chamber having an inlet and an outlet through which the flowstream respectively enters and exits the chamber; and a magnetic source able to be selectively activated with respect to the treatment chamber, such that, when activated, the magnetic source induces magnetism in at least some of the particulate feed material located in the chamber. This allows the introduction of a high gradient magnetic field to effectively magnetise both the weakly and strongly magnetic particulates for subsequent removal by setting or other techniques. When the magnetic source is deactivated, the flow stream of feed material dissipates the deposits of magnetised material from around the source to reduce the possibility of any flow restrictions and maintain the effectiveness of magnets.
