Abstract: La divulgation décrit des mousses céramiques, notamment d'argile et un procédé de préparation desdites mousses. Une fois que l'on a obtenu un mélange constituant une barbotine, on fait mousser cette dernière sous addition de quantités contrôlées d'un gaz, notammant de l'air, assurant ainsi la reproductibilité de mousse ayant des propriétés physiques prédéterminées. Il est préférable de faire sécher la mousse dans des conditions où la température est hétérogène et en absence de ventilation. Cette opération peut s'effectuer en disposant la mousse sous des éléments chauffants à une température variant de 30.degree.C au départ à 100.degree.C vers la fin du séchage tout en évitant pratiquement toute ventilation au voisinage de la mousse. Ce procédé a pour principal avantage de permettre le contrôle des propriétés physiques de la mousse ainsi obtenue. On peut utiliser cette mousse comme absorbant industriel, isolant acoustique, coupe-feu, isolant thermique, etc. en faisant varier la densité de ladite mousse.

Abstract: ABSTRACT OF THE DISCLOSURE       Production of oxygen from air, by compressing air to relatively low pressure, e.g. to about 3 atmospheres, and passing the compressed feed air to alternate passages of a reversing heat exchanger in heat exchange relation with a nitrogen waste stream, whereby water vapor and CO2 in the feed air are frozen on the surface of the heat exchange passage.  By reversing the flow streams the low pressure nitrogen waste stream now flows through the feed air passage.  This causes sublimation or evaporation of the CO2 and water vapor.  A portion of the feed air is withdrawn at an intermediate point in the exchanger and is further cooled in a heat exchange passage in the lower portion of a non-adiabatic fractionating device.  The cooled feed air withdrawn from the heat exchanger is partly condensed by evaporating oxygen liquid product, and is fed to the partial condensing zone of the fractionating device, whereby oxygen-rich liquid is condensed and withdrawn, and nitrogen is removed as overhead.  The nitrogen is expanded in a turbine and is passed in countercurrent heat exchange relation to the partial condensing zone, thereby providing refrigeration to the system. The oxygen-rich liquid is reduced in pressure, e.g. to about 1 atmosphere, and is fed to the partial evaporation zone of the fractionating device whereby nitrogen-rich vapor is removed as overhead, and oxygen of about 95% purity is removed as a liquid. The waste nitrogen stream exiting the heat exchange passage of the fractionating zone is passed through one of the reversing passages of the reversing heat exchanger, the fractionation being carried out so that there is only about a 3°R temperature difference between the nitrogen waste stream and the feed air at the cold end of the reversing exchanger.  The oxygen product is passed through a separate passage of the reversing exchanger also in countercurrent heat exchange relation with the feed air.

Abstract: ABSTRACT OF THE DISCLOSURE Valves connected to dip tubes in conventional pressurized "aerosol"-type containers for dispensing materials which react ox cure upon dispensing (e. g. moisture-curable polyurethanes), are protected against premature failure by introducing a small amount of dry, inert gas into the dip-tube shortly after charging the container.  The gas (e. g. nitrogen) acts as a barrier to prevent contact between the product in the container and the valve mechanism prior to use of the product.  Preventing such con-tact avoids premature hardening of pro-duct in the valve mechanism caused by reaction of product with moisture.

Abstract: CURLING BRUSH     Abstract of the Disclosure A curling brush has been designed to provide two main ice scrubbing surfaces instead of just one as found in a curling brush of traditional design, thereby making the useful life of the new brush at least twice that of a traditional brush.  The new brush also provides smaller ice scrubbing surfaces making it possible to achieve a greater brushing effect when desired without pushing the brush on the ice with a greater force which is the only way a greater brushing effect may be achieved with a traditional brush.  The symmetrical design of the new brush eliminates the problem of possible ice damage resulting from inadvertent use of the wrong side of the brush head as sometimes happens during use of a traditional brush, it provides a uniform target for a player throwing a curling stone unlike the asymmetrical traditional brush, and it makes the use of a brush for the purpose of cleaning the running surface of a stone before throwing the stone much easier.  The design of the new brush also permits the effective use of an ice cleaning material on the head which will not readily break down thus eliminating the problem of bristle  debris common to traditional brushes.
