Title: Lunettes de ski avec dispositif d`eclairage
Inventor: LAVOIE DAVID D L
IPC: A61F9/02
Filed: 2004-07-06
Abstract: Les lunettes de ski ont toujours servi à protéger les yeux des skieurs, à améliorer la vue de ceux-ci et à ajouter un élément d'esthétisme à un habit de ski. Le s lunettes de ski sont utilisées très souvent durant la saison d'hiver. Comme on le sait, les journées d'hiver sont habituellement plus courtes, donc il fait noir beaucoup plus tô t. C'est pourquoi dans la présente invention, les lunettes de ski sont munies de lumières (D.E.L.) ( diode émettant de la lumière ) qui optimisent énormément la vision du skieur. Elles ne sont plus passives, elles deviennent actives et modifient l'environnement de leur détenteur. Elles éclairent tous les obstacles qui se trouvent devant lui. No n seulement il voit mieux les autres skieurs qui l'entourent, mais eux se rendent compte de sa présence beaucoup plus vite et cela a pour effet d'éviter des collisions et des chute s douloureuses. De plus, avec la multitude de lumières de couleurs disponibles, le nombre et la façon de les placer sur les lunettes; cela accentue les différences entre les habits des skieurs. Même à un kilomètre, il vous est possible de distinguer votre ami des autres skieurs. Le concept de lunettes en question ici est constitué d'un fil qui a pour foncti on d'acheminer l'électricité de la pile vers les lunettes. Ce fil peut aussi servir de lien entre le manteau du skieur et les lunettes, donc elles ne se retrouvent plus jamais hors de la portée du skieur.

Title: Use of high carbon coal ash
Inventor: WHELLOCK JOHN GRAHAM
IPC: F27B3/18
Filed: 2003-01-28
Abstract: A synthetic slag is produced by a high temperature combustion reaction between coal ash having a high carbon content, and a source of lime such as cement kiln dust. The carbon content of the coal ash is oxidized by oxygen gas, which typically is derived from air or an air/oxygen combination in an exothermic reaction and the heat generated is exploited in the melting process. In this way the gaseous products will typically comprise nitrogen, unreacted oxygen and carbon dioxide, and heat energy can be readily recovered from the hot off gas products evolving during the combustion reaction. The synthetic slag may be pelletized and employed as lightweight mineral aggregate or milled to cement fineness to provide slag cement.
