Title: Scanning laser demolding of ophthalmic lenses
Inventor: WALKER CRAIG W
IPC: B29C37/00
Filed: 1997-09-08
Granted: 2006-08-15
Abstract: An apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation is applied to at least one of the mold portions in a predetermined scanning pattern through the intermediary of galvanometer-driven mirrors. Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force breaks the polymerized lens/polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions separate. The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.

Abstract: The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention provides a method for increasing the rate of strength gain of a hardenable mixture containing fly ash by exposing the fly ash to an aqueous slurry of calcium oxide (lime) prior to its incorporation into the hardenable mixture. The invention further relates to such hardenable mixtures, e.g., concrete and mortar, that contain fly ash prereacted with calcium oxide. In particular, the fly ash is added to a slurry of calcium oxide in water, prior to incorporating the fly ash in a hardenable mixture. The hardenable mixture may be concrete or mortar. In a specific embodiment, mortar containing fly ash treated by exposure to an aqueous lime slurry are prepared and tested for compressive strength at early time points.

Filed: 1996-10-25
Granted: 2002-06-18
Abstract: Ce système de diagnostic surveille et mémorise des signatures ou caractéristiques thermiques pendant un mode de fonctionnement au moins d'un ustensile de cuisson. Ces signatures ou caractéristiques thermiques sont recueillies, par le même capteur de température que celui servant à régler la température de l'ustensile, puis mémorisées dans un tableau de consultation par exemple. L'avantage réside en ce que ceci évite le recours à des capteurs spéciaux ou à des circuits d'interface. Ces signatures ou caractéristiques thermiques peuvent inclure des gradients de température du premier ordre ou d'ordre plus élevé ainsi que des profils de température. Les signatures thermiques mémorisées donnent une base à partir de laquelle ce système de diagnostic peut détecter et déterminer si l'ustensile de cuisson fonctionne dans des conditions normales.

Abstract: A decoy flare for infrared (~R) seeking missiles comprises a tubular shell with a cover member hermetically sealed to an outer front edge of the tubular shell to form a container for a pyrophoric liquid.  The cover member has a central rupturing disc that ruptures at a predetermined pressure, a nozzle cap with a nozzle opening being attached to the cover member adjacent an exterior surface of that rupturing disc.  Pressure applied by a mechanism to the pyrophoric liquid can rupture the rupturing disc and eject the pyrophoric liquid through the nozzle.  A pre-heating chamber formed by an enclosure surrounds the nozzle opening in order to provide for more reliable ignition of the pyrophoric liquid at high altitudes and low flow rates, that enclosure having an outer surface containing a number of perforations through which air can enter the pre-heating chamber and through which pyrophoric liquid can be ejected from the chamber into the atmosphere.
