Inventor: KUHN JACQUES
IPC: A47J27/212
Filed: 1990-10-23
Abstract: A water kettle is equipped with a handle, a first end of which is joined to lower regions of the side of the kettle by a hinge, and a second end of which is fitted on the diametrically opposite side with a spout lid for covering (and opening) the kettle's spout. When the kettle is in the rest position, as a result of its weight the handle will drop until the handle comes to stop on the spout and the spout lid covers the spout opening. When the kettle is lifted by the handle or tipped into the pouring position, the handle swings back to a stop in the spout and the associated spout lid is removed from the spout opening. Following this swiveling movement, the raised spout lid is brought into a position which deflects steam flowing out of the spout opening in such a way that a user's hand holding the handle is not directly exposed to the steam. The spout lid is provided with a device for emitting an acoustic signal when the boiling point is reached in the interior of the kettle. If desired, the water kettle may further include a second, larger filling and cleaning opening which is enclosed by a close-fitting lid to facilitate filling and cleaning of the interior of the kettle.

Abstract: On peut simplifier le revêtement à l'aide de métaux à point de fusion élevé en ajoutant à un métal à pont de fusion élevé suffisamment d'aluminium pour faire un alliage à bas point de fusion qu'on applique, qu'on fait adhérer in-situ, et qu'on soumet ensuite à une élimination par lessivage d'une certaine quantité ou d'une grande partie de l'aluminium. La surface résultante est poreuse et elle pourra recevoir et permettre l'adhérence de revêtements de surface (12). La surface lessivée peut être pyrophorique et le revêtement de surface peut être combustible par voie exothermique. La poudre pyrophorique peut également être déposée sur des fibres de bore ou de carbone ou frittée avec des particules combustibles (16). On peut obtenir la porosité en soumettant la pièce à des conditions de diffusion en la mettant en contact avec un matériau d'apprauvrissement comme des aluminures pulvérulents à tenuer en nickel faible ou forte ou à teneur en cobalt faible ou forte. Les particules d'aluminium peuvent être déposées par électrophorèse sur la feuille et elles se diffusent ensuite. On améliore l'élimination par lessivage de l'aluminium avec du caustique lorsque celui-ci comprend un peu de H2O2 dans la cuve de lessivage (22). Le traitement ultérieur de la surface lessivée, avec un acide faible, améliore la pyrophoricité, et le pliage de l'élément pyrophophorique augmente le temps de maintien de la température élevée résultant de l'action pyrophorique. La feuille de résine contenant des particules pyrophoriques constitue un leurre efficace.

Abstract: A piston-type point of lubrication magnetic flow indicator (10) providing a barrel (20) interfit with a bushing (24) having a cylinder portion (70) penetrating the barrel (20) coaxially and a magnetic piston (74) which reciprocates closely interfit inside the cylinder portion (70) of the bushing (24). Lube oil enters an inlet port (12) of the bushing (24), flows through a check valve (40) into the cylinder portion (70), and impinges on one end of the magnetic piston (74). The impinging causes the magnetic piston (74) to move in the cylinder portion (70) uncovering at least one port (80a,b) formed through the cylinder portion (70) which opens the cylinder portion (70) to the barrel, directing flow thereto. The lubricating oil flows through the barrel (20) and out of an aperture (106) formed at a forward end of the barrel (20) to a lubrication spray nozzle (S). Movement of the magnetic piston (74) through the cylinder portion (70) triggers a magnetic reed switch (120) mounted on an outside circumference of the barrel (20) and generally overlying the relative axial position of the piston (74) in the cylinder portion (70). The opening and closing of the reed switch (120) can be electrically monitored by electronic lubrication monitoring systems or controls (M) as are known.

Abstract: Three signal samples (A25, C26, B27) of a digital signal DATA are taken simultaneously in three different time positions (t25, t26, t27) of this signal and separated by a small time interval (T). As long as the three signal samples are equal it may be deduced therefrom that the three time positions occur within the duration of a same data bit of DATA and a new set of three time positions (t24, t26, t28) of which the time interval separating them is increased is then taken, the latter set being thus "expanded" over a larger region of this data bit. If, on the contrary, a signal sample (B28) is different from the two others (A24, C26) it may be deduced therefrom that only two time positions (t24, t26) occur within the duration of a data bit. A new set of three time positions (t24, t25, t26) is then taken with the initial small time interval (T) and with the new medium time position shifted over this time interval (T) to the left or to the right depending on which of the signals samples is different from the others. If the three signal samples (A24, C25, B26) taken in the three new time positions are then equal, the above process is repeated. In conclusion, when the "largest" set of time positions (t12, t20, t28) is obtained, the medium time position thereof (t20) always occurs in the middle of a data bit and the signal sample (C20) taken in this medium time position is optimum for representing this data bit and for generating another digital signal synchronized with the clock signal CLOCK.
