Abstract: La présente invention concerne un sac à air 9 pour appareil respiratoire 1 à circuit semi-fermé, en résine de polyuréthanne, moulé en une pièce et sans joint. L'ouverture du sac 9 est pourvue d'un dispositif fileté permettant de l'attacher facilement et rapidement à l'appareil. L'absence de joint simplifie le procédé de fabrication, puisqu'elle élimine l'étape autrement obligatoire du contrôle de la résistance des joints. La résine de polyuréthanne possède une résistance à la déchirure supérieure à celle des matériaux utilisés dans la fabrication des sacs existants, et, par conséquent, rehausse la durabilité et autres qualités assimilées du sac de cette invention. De plus, ce sac peut être fabriqué par le procédé de moulage par soufflage, lequel se prête à la fabrication en grandes séries et permet d'obtenir des sacs de dimensions uniformes.

Title: Process for the production of ultrafine particles
Inventor: MIAO WIE-FANG
IPC: C01F17/224
Filed: 1996-08-28
Abstract: A new, cost effective process for the production of ultrafine particles which is based on mechanically activated chemical reaction of a metal compound with a suitable reagent. The process involves subjecting a mixture of a metal compound and a suitable reagent to mechanical activation to increase the chemical reactivity of the reactants and/or reaction kinetics such that a chemical reaction can occur which produces a solid nano-phase substance. Concomitantly, a by-product phase is also formed. This by-product phase is removed so that the solid nano-phase substance is left behind in the form of ultrafine particles. During mechanical activation a composite structure is formed which consists of an intimate mixture of nano-sized grains of the nano-phase substance and the reaction by-product phase. The step of removing the by-product phase, following mechanical activation, may involve subjecting the composite structure to a suitable solvent which dissolves the by-product phase, while not reacting with the solid nano-phase substance. The process according to the invention may be used to form ultrafine metal powders as well as ultrafine ceramic powders.  Advantages of the process include a significant degree of control over the size and size distribution of the ultrafine particles, and over the nature of interfaces created between the solid nano-phase substance and the reaction by-product phase.

Title: One-component chemically curing hot applied insulating glass sealant
Inventor: NIEGA PAT
IPC: C03C27/12
Filed: 1996-10-23
Abstract: This invention relates generally to sealants for insulating glass units. More specifically this invention is a one-component, hot applied, chemically curing sealant for edge sealing insulating glass units.  The sealant contains a thermoplastic hot melt resin blended with an atmospheric curing resin. The hot melt resin functions as the meltable component during the initial application, and supplies strength immediately upon cooling. The polymer phase then begins to cure by reaction with atmospheric oxygen and/or moisture to form a cross-linked thermoset elastomer which is temperature resistant. At this point, the hot melt resin functions as an inert plasticizer within the cured polymer phase. The sealant of the present invention may additionally include plasticizers, fillers, pigments, catalysts and the like.
Patent CA-2235883-A1 (CA)
Title: Propane recovery process
Inventor: SORENSEN JAMES N
IPC: C07C7/00
Filed: 1996-11-01
Abstract: Increased recovery of propane, butane and other heavier components found in a natural gas stream is achieved by installing an absorber upstream from an expander and a separator. The separator is downstream from the expander and returns the liquid stream generated by the separator back to the absorber.  Additionally, the recovery of propane, butane and other heavier components is enhanced by combining the upper gas stream from a distillation column with the upper gas stream from the absorber prior to injecting this combination into the separator. The upper gas stream removed from the separator is then subsequently processed for the recovery of a predominantely methane and ethane gas stream while the bottom liquid stream from the absorber is subsequently distilled for the generation of a stream consisting predominantely of propane, butane and other heavy hydrocarbon components. Alternate embodiments include an additional reflux separator in the system, or substitution of an additional absorber for the separator.

Abstract: An object search method and an object search system which reduce the time needed for coordinate transformation of a plurality of objects to be displayed as three-dimensional view data through viewing transformation. The system determines a reference box which circumscribes a view volume, created according to an eyepoint. The system determines a bounding box for each object. Each bounding box circumscribes the corresponding object. A 6-d tree, composed of a plurality of nodes each having keys composed of the coordinate components of each bounding box, is prepared beforehand. With the coordinate components of the reference box as a search condition, the system searches the 6-d tree for bounding boxes included in the reference box.      Then, the system performs coordinate transformation only on the objects corresponding to the obtained bounding boxes.
