Patent CA-2245574-A1 (CA)
Inventor: FRUHSTORFER HEINRICH
IPC: A61B5/15
Filed: 1997-02-04
Abstract: A skin cutter is disclosed for painlessly extracting small blood amounts from human or animal tissue. A blade (13) is made to vibrate by means of an oscillator (14, 32), is slowly lowered into the tissue and withdrawn again. In a first embodiment, the blade vibrates substantially in a parallel direction to the cutting edge of the blade and to the surface of the tissue. In the second embodiment, the blade vibrates substantially in the perpendicular direction to the surface of the tissue. The advantage of the disclosed devices is that the pain caused by pricking is reduced.

Title: Spherical valve for flow control of particulate solids and gases
Inventor: FLORES VERDUGO MARCO AURELIO
IPC: F16K5/20
Filed: 1997-03-04
Abstract: A valve for feeding abrasive particulate material to, and removal of particulate material from a pressurized vessel, adapted to operate at temperatures above 500 °C, comprises a valve structure wherein a single shutoff member of generally spherical shape performs both functions of shutoff the particulate material and the gas-tight sealing by means of a resilient inflatable circular seal element which engages the convex side of said shutoff member. Said seal element is inflated and cooled by a pressure regulated and continuously flowing stream of liquid water. The seal element is protected from being damaged at high temperatures by contacting it with the cooled shutoff member when the valve is closed and with a cooled circular extension of the shutoff member when the valve is open.

Abstract: This invention relates to a new and economically viable method for making a THERMOPLASTIC Multilayer Tubing which comprises of at least three layers in which the inner layer P.J.1 is a BARRIER layer which does not allow the permeation and diffusion of vapours, gases, moisture, aroma and flavors. The P.J.1 layer which is totally inert, odourless, non-soluble in water, alcohols, beverages, syrups and alike is the contact layer. The P.J.I is a copolyester with a general formula (C10H8O4)n without any hazardous ingredients and has a melting point range about 160°C and density between 0.9 and 1.0 g/mL. The outer surface layer comprises of polyethylene, P.E., with general formula (C2H4)n having melting point range about 180°C. It is bonded to the non permeable P.J.1 layer by P.J.2 layer which is chemically stable plastic material under processing condition and is composed of having a general formula C8H16O and density about 0.9 and melting point about 55°C. The applicants have developed processing conditions for P.J.1 which meet the attributes of desired tubing and solves the long standing problem of vapour and flavour transmission and adsorption in beverage carrying and dispensing. The film form of P.J.1 can finds its application in the food packaging industry to prevent loss of moisture, flavour and taste.  The realization is that P.J.1 is environmentally friendly, and it is envisioned to have numerous potential applications. These applications can draw upon the P.J.1's properties at competitive cost.

Title: Procede de decortication d'un materiau vegetal
Inventor: KELLY DAVID H
IPC: D01B1/22
Filed: 1997-07-15
Abstract: On décrit un procédé pour séparer un matériau ligneux de fibres végétales (20), dans lequel on utilise une pluralité de zones de pliage (18) de matériau ligneux, et qui consiste à alimenter le matériau végétal vers une première puis vers une seconde de ces zones de pliage, au fur et à mesure que des surfaces de tirage et de pliage (22) se déplacent dans ces zones de pliage (18). Les surfaces de pliage et de tirage se déplacent dans ces zones à des vitesses de fonctionnement différentes, de façon que les surfaces de pliage et de tirage de zones adjacentes tirent sur le matériau végétal pour séparer les fibres du matériau ligneux. Comme les surfaces de pliage et de tirage impriment d'abord une force de tirage ou de décorticage sur la longueur de la fibre à l'endroit où celle-ci présente la plus grande résistance, le matériau ligneux peut être déplacé et arraché dans le sens de la longueur sans endommager ou rompre la fibre. L'étape dans laquelle on utilise les zones de pliage (18) peut comprendre l'étape mettant en oeuvre des premier et second ensembles (14) de cylindres cannelés présentant des surfaces à cannelures, destinées au pliage et au tirage et s'étendant radialement. Le matériau végétal est alimenté vers la première zone de pliage, entre le premier ensemble de cylindres cannelés, puis vers la seconde zone de pliage, entre le second ensemble de cylindres cannelés. De préférence, on a monté également une troisième zone de pliage et on fait se déplacer les cannelures de pliage et de tirage à travers ces première, seconde et troisième zones à des vitesses de fonctionnement croissant progressivement.

Patent CA-2262049-A1 (CA)
Inventor: RAMMAL MUHAMMAD
IPC: F16K31/70
Filed: 1999-02-16
Abstract: A thermally sensitive valve for initiating actuation of apparatus in response to an increase to a predetermined level of ambient temperature has a tubular body adapted to be fitted to a conduit containing pressurized fluid and having an inlet through which such fluid may enter a passageway in the body. The valve body also has a fluid outlet and a piston which normally occupies a position which prevents the exhaust of fluid from the passageway. The piston is biased by the pressure of the fluid to a position which enables the exhaust of fluid from the passageway, but movement of the piston to such position is restrained by a linkage having a pair of links bonded together by a eutectic material which melts in response to a rise in ambient temperature to a predetermined level, thereby enabling the links to separate and remove the restraint on the piston. The linkage is exposed on all sides to ambient temperature.

Title: Data-driven process generator
Inventor: REDHED DAVID DICKEN
IPC: G06Q10/06
Filed: 1999-03-26
Abstract: A method of analyzing process steps and creating a data-driven process is disclosed. A data-driven process is a process that has its steps sequenced according to data relationships among the process steps, and the rule that a step is placed in the sequence only when all of its inputs exist. A data-driven process can only be created when all steps may be placed in the sequence according to this rule. The method determines if a process is data-driven by checking to see if any of the individual steps causes one or more errors which would prevent data-driven sequencing, and, if any errors are found, error correction is attempted in order to create a data-driven process.
