Abstract: The safety device (7) is associated with a hydraulic connection (4) of a hose (3) supplying water to a machine for washing laundry or dishes, and it takes effect in the event of leaks between the inner tube (8) and the outer sheath (9) of the hose (3) so as thus to close the passage (15) of water through the connection (4). According to the invention, this safety device (7) is arranged in a cylindrical housing (16) coaxial with the connection (4). It comprises an annular piston (25) mounted movably in the axial direction of the connection between the housing (16) and the water passage (15). The pressure of the possible leaks displaces the piston (25) which thus releases a pin (22) causing the closing of the water passage (15) as a result of the displacement of an axially moveable shutter (20). <IMAGE>

Title: Systeme d'analyse de gaz utilisant des arrivees de gaz tampon en vue de proteger les elements optiques associes
Inventor: MILES SCOTT D
IPC: G01N21/15
Filed: 1991-05-10
Abstract: L'invention se rapporte à une cuvette d'analyse de gaz (10), qui est placée à l'intérieur d'une cavité résonnante optique d'un système d'analyse de gaz. Cette cuvette comprend un écoulement (50A, 50B) de gaz tampon formant un barrage, en vue de protéger les éléments optiques (20-22) du système d'analyse. La cuvette d'analyse comporte une ouverture d'entrée (34) servant à introduire un échantillon gazeux (52) dans la chambre d'analyse (26) de la cuvette. Deux orifices d'entrée (40, 42) pour le gaz tampon, situés chacun à l'une des deux extrémités de la cuvette, servent à introduire un écoulement de gaz tampon (50) qui est amené à passer par les éléments optiques (20-22) du système à proximité adjacente des extrémités de la cuvette. Deux orifices de sortie (44, 46) sont placés aux extrémités de la chambre d'analyse et servent à en retirer le mélange gaz tampon et échantillon gazeux. L'écoulement (50) de gaz tampon sert à confiner l'échantillon gazeux (52) dans la chambre d'analyse et à réduire les effets néfastes qui risqueraient de se produire par contact de l'échantillon gazeux avec les éléments optiques du système. En prévoyant un écoulement constant non turbulent de gaz à proximité adjacente des éléments optiques du système, on évite les variations négatives de l'indice de réfraction, ce qui réduit les orientations de faisceaux et les effets de Schlieren qui risqueraient de se produire avec l'utilisation de fenêtres de Brewster ou d'autres éléments optiques destinés à contenir l'échantillon gazeux dans la cuvette d'analyse. L'écoulement de gaz tampon dans la cuvette d'analyse élimine la nécessité de recourir à des fenêtres pour la cuvette de gaz qui se caractérisent par des pertes intrinsèques. On réduit ainsi au minimum les pertes qui entraînent une réduction de la puissance de circulation dans la cavité ainsi qu'une réduction de la force des signaux.
