Abstract: Suivant les années, de 82 à 85% des blessures ou des décès ayant trait au feu se produisent au domicile d'après les Statistiques en Prévention des Incendies. La principale alternative offerte aux particuliers d'éteindre un début d'incendie au domicile est l'extincteur qui a des qualités reconnues, mais aussi des inconvénients. Lors d'un incendie il fait des dégâts, se vide rapidement, n'est pas toujours manipulé adéquatement et provoque un gros nettoyage. Une vérification est nécessaire entre 13 et 18 mois et le recharger entraîne des coûts supplémentaires. Ces éléments ont justifiés nos recherches qui ont abouties à la création de l'OCCIFLAME, dont le but est d'éteindre un début d'incendie et d'arrêter la propagation des flammes en supprimant l'apport d'oxygéne. L'OCCIPLAME est une pièce de textile en coton type serviètte, de dimension moyenne de 97 cm X 105 cm, qui a été traité avec des sels ignifuges. Il est conditionné dans une boite en carton dont l'ouverture est pré-découpée, afin de pouvoir être utilisable en quelques secondes. Prêt à l'emploi, sans aucun entretien, il est très simple d'utilisation puisqu'il suffit d'ouvrir son contenant, de prendre dans chaque main un rebord de l'OCCIFLAME, et de le déposer sur les objets ou matériaux en feu. L'OCCIFLAME est un concept innovateur grand public, non toxique et sans amiante, propre lors d'un feu, sans aucun entretien. Il a passé avec succès les normes Nord-américaines et Européennes les plus sévères, et sa durée de vie testée, est équivalente à la durée de vie de son support. Pour tout individu du plus jeune au plus vieux l'OCCIFLAME sera plus pratique à utiliser que l'extincteur même s'ils concourent l'un et l'autre vers le même but, à savoir: Sauver des biens matériels, des vies humaines...

IPC: C11D10/04
Filed: 1994-09-19
Abstract: A storable, substantially water-free flowable surfactant mixture containing 40% by weight to 70% by weight of a nonionic surfactant of the formula R1-(OC2H4)n-OH wherein R1 is an alkyl or alkenyl group containing 10 to 20 carbon atoms and an average degree of ethoxylation n of from 1 to 8; 20% by weight to 50% by weight of a nonionic surfactant , liquid at room temperature, of the formula : R2-(OC2H4)r-(OC3H6)p-OH wherein R2 is an alkyl or alkenyl group containing 10 to 20 carbon atoms, an average degree of ethoxylation r of from to 8 and an average degree of propoxylation p of from 1 to 6; and 1% by weight to 10% by weight of a C10 to C22 carboxylic acid and/or alkali metal salts thereof.   The flowable surfactant mixture provides a base for forming a pseudo-plastic detergent formulation. The pseudoplastic detergent formulation is formed by introducing solid materials such as an anionic surfactants, solid foam regulators, detergent builders and the like. When the solid materials are introduced into the substantially water-free, flowable surfactant mixture, a paste-form detergent is formed. The paste-form detergent does not flow under the action of gravity but upon introducing shear energy into the mixture, the viscosity is reduced and the composition flows under the force of gravity. Upon removing the shearing forces, the composition returns to its pseudoplastic form.

Inventor: PINCUS JONATHAN D
IPC: G06F11/36
Filed: 1995-08-09
Abstract: An error detection mechanism for detecting programming errors in a computer program. A component of the computer program, e.g., a procedure or function of the computer program, is analyzed to determine the effect of the component on resources used by the computer program. A component is analyzed by traversing the computer instructions, i.e., statements, of the component and tracking the state of resources used by the components as affected by the statements of the component. Each resource has a prescribed behavior represented by a number of states and transition between states. Violations in the prescribed behavior of a resource resulting from an emulated execution of the statements of the component are detected and reported as programming errors. Resources used by two or more components are modelled by modelling externals of the components. The effect of execution of a component on externals and resources of the component is determined by traversing one or more possible control flow paths through the component and tracking the use of each external and resource by each statement of each control flow path. Once the effect of execution of a component on externals and resources of the component is determined, a model of the component is created and used to model externals and resources of other components which invoke the modelled component.
