Patent CA-2104457-A1 (CA)
Inventor: MATSUMOTO HIROYUKI
IPC: B29C45/17
Filed: 1992-12-24
Abstract: The invention relates to a hollow injection-molding method of forming a hollow portion in molten resin in a mold cavity by introducing a pressurized fluid, and also to a pressurized fluid introducing and discharging apparatus therefor, and has an object of eliminating the backflow of the molten resin to a pressurized fluid passage and surly introducing and rapidly discharging the pressurized fluid.    A gap between a cylindrical sleeve and a shaft core inserted into the sleeve is used as the pressurized fluid passage.  The front end of the shaft core is projected into a mold so as to be beyond the sleeve, and the projection portion of the shaft core is used as a guide face.  By sliding the shaft core, the state of an opening portion of the pressurized fluid passage in the side of the mold is changed from a narrowed state where the pressurized fluid can pass through the opening portion but the molten resin cannot enter the opening portion, to a widened state or vice versa.    The width of the opening portion of the pressurized fluid passage in the side of the mold is changed by sliding the shaft core, whereby the backflow of the molten resin is prevented from occurring and the pressurized fluid can be rapidly discharged.  The provision of the guide face allows the pressurized fluid to be surely introduced.

Title: Improved process for alkylation of aromatics with linear olefins derived from a linear paraffin dehydrogenation step
Inventor: KOCAL JOSEPH A
IPC: C07C15/02
Filed: 1993-09-13
Abstract: Aromatic byproducts normally formed in the dehydrogenation of normal paraffins to linear monoolefins have been found to be are detrimental in the usual processes of aromatic alkylation using the dehydrogenation product mixture as an alkylation feedstock. In particular, when solids are used as the alkylation catalysts with recycle of the unreacted feedstock to the dehydrogenation reactor the aromatic byproducts increase to a level where they exert a significant decrease in the stability of the alkylation catalyst. When the aromatic byproducts are removed in whole or in part alkylation may be performed at a substantially lower temperature, which affords alkylated aromatics whose alkyl portion has greater linearity than that observed at a higher alkylation temperature.

Patent CA-2113604-A1 (CA)
Inventor: WALLESTAD STEVEN D
IPC: B60T13/38
Filed: 1994-01-17
Abstract: A valve assembly for use with spring-set air-release vehicle parking brakes comprises a particular arrangement of conventional components providing desired spring brake operational characteristics heretofore requiring costly, complex specially-designed units.  The valve assembly typically employs a plurality of interconnected check valves in combination with pressure protection and quick release valves to provide the desired characteristics.  These include a system whereby at startup pressurized air from the tractor fills the trailer reservoir tanks and the spring brake chambers simultaneously.  The valve assembly also assures that if during tractor-trailer operation the supply air from the tractor is severed or otherwise lost, service brake air in the trailer reservoir tanks is retained at a sufficient pressure to provide adequate service brake operation.  Similarly, if pressurized air in the trailer reservoir tanks is lost, sufficient pressure is maintained in the system to keep the spring brakes released for safe parking of the tractor-trailer combination.

Abstract: L'invention consiste en un procédé d'isomérisation d'hydrocarbures aliphatiques linéaires dont le nombre d'atomes de carbone est supérieur à 6 pour en faire des hydrocarbures ramifiés présentant ainsi un meilleur indice d'octane.      Le procédé consiste à faire passer l'hydrocarbure dilué dans l'hydrogène sur un catalyseur à basa d'oxycarbure de molybdène qui est obtenu soit à partir de carbure de molybdène que l'on soumet à une oxydation ménagée, soit à partir d'oxyde de molybdène MoO3 que l'on réduit par un hydrocarbure.      L'avantage de l'invention par rapport aux catalyseurs de l'art antérieur est qu'il permet d'atteindre une sélectivité élevée en isomères ramifiés quel que soit le taux de conversion ce qui valorisa les coupes pétrolières n-heptane et n-octane.
Patent CA-2136273-A1 (CA)
Title: Fiber mat forming method, machine and product
Inventor: CADIEUX SERGE
IPC: D04H1/22
Filed: 1994-11-21
Abstract: A fiber mat as well as its method of fabrication and forming machine are described. The fiber mat comprises a plurality of fibers which are limitations bound together and distributed throughout the mat, and wherein some of the fibers are inclined towards a central horizontal plane of the mat. The inclined fibers on opposed sides of the mat have opposed angles of inclination whereby the mat, when used as insulation, can be easily separated substantially along the central horizontal plane by applying a pulling force on one side or opposed sides of the mat in the direction of the inclined fibers. The forming machine is characterized by having two forming surfaces, one disposed horizontally and the other vertically whereby the mat is formed with higher density towards the opposed flat horizontal surfaces of the mat and the lower density is distributed along the central horizontal plane. By having these opposed forming surfaces there is provided a former which provides double formation capacity capable of providing a mat with improved density profile, provides higher air flow, less shingling effect, and the production of a mat which can be easily split substantially in the middle along the central horizontal plane when used as an insulating mat. Because the former doubles the capacity of fibers and also the thickness of the formed mat, it is possible to compress the mat to form fiber boards.
