Title: Magnetic control valve for a suction powered pool cleaner
Inventor: FORBES JUSTIN A
IPC: E04H4/16
Filed: 2002-05-10
Abstract: A magnetic control valve is provided in a suction powered pool cleaner (10) of the type for vacuuming dirt and debris from submerged floor and side wall surfaces of a swimming pool. The pool cleaner comprises a head defining a suction inlet (34) for vacuum inflow of water and debris into a plenum chamber (40), and further through a suction tube (42) adapted for connection via a vacuum hose (14) to a conventional pool water filtration system (12). The control valve includes an oscillatory valve member (64) movable between open and substantially closed positions relative to an upstream end of the suction tube to produce pressure fluctuations causing the cleaner to advance in steps over submerged pool surfaces. Oscillatory driving of the valve head is assisted by permanent magnets (74, 76, 78) mounted on the valve member and cleaner head to generate repulsion forces as the valve head respectively approaches the open and closed positions.

Le terme de réduction des erreurs de troisième niveau représente une troisième différence de formule de résistivité ??3¿¿x.rho.x?. Le terme de réduction des erreurs de deuxième niveau représente une deuxième différence de résistivité ??2¿¿.rho.x?. Les termes de réduction des erreurs de troisième niveau et de deuxième niveau sont délibérément définis en vue de se rapprocher d'un comportement linéaire et parabolique local. Une constante de régularisation .gamma. est utilisée pour ajuster le poids conféré aux termes de réduction des erreurs de troisième et/ou de deuxième niveau. Un ordinateur système (62) utilise des procédés numériques pour résoudre le modèle de régularisation pour les valeurs de résistivité .rho., d'où l'obtention d'un niveau d'erreur <I>E</I> acceptable préétabli.

Abstract: Cette invention porte sur des formulations conçues pour former une composition en mousse à base de ciment, sur la composition en mousse à base de ciment elle-même, sur un procédé de production d'un liant hydraulique en mousse ainsi que sur un procédé permettant de véhiculer et d'appliquer la mousse obtenue sur un substrat. Une bouillie de ciment pompable est formée, laquelle bouillie est mélangée à un gaz tel que l'air puis est soumise à une turbulence mécanique pour qu'on obtienne des bulles de gaz ainsi qu'une mousse qui est de préférence stabilisée par un agent stabilisant de mousse tel que l'alcool polyvinylique présent dans la bouillie. La mousse est ensuite acheminée vers une buse ou autre point de distribution adéquat à partir duquel elle est appliquée, par exemple vaporisée, de préférence uniformément, sur un substrat à garnir. Avant l'application, un accélérateur de prise est de préférence injecté, ce qui entraîne la transformation de la mousse en gel, ce qui permet d'améliorer la tenue du produit sur un substrat. Le matériau vaporisé adhère au substrat et durcit pour former un revêtement isolant sur le substrat. Cette invention concerne également des compositions sèches renfermant un liant à base de ciment hydratable, un agent stabilisateur de mousse mécanique et éventuellement un composant fibreux, un retardateur de prise et un agent entraîneur d'air. Cette composition permet d'obtenir, après ajout d'eau, de gaz et d'une turbulence mécanique, une mousse durcissable pouvant être vaporisée sur un élément structurel en acier et qui, après vaporisation, adhère à l'élément dans la forme mousse et après durcissement. Après avoir durci, la mousse constitue un revêtement adhérent qui protège l'élément contre le feu et la chaleur.
