Inventor: DOMINGUE MICHEL

Abstract: S . L'adhérence au sol des pneus d'un véhicule s'avère généralement insuffisante dans les conditions hivernales sévères ou, lorsque le véhicule doit être déplaçé sur certains terrains sablonneux ou boueux. Afin d'accroitre, dans de telles conditions, l'adhérence au sol des roues sur des distances pouvant être relativement longues, les conducteurs des véhicules font généralement usage d'un ensemble chaînes et chaînons montés en saillie sur le pneu. Ces ensembles ne sont pas faciles à installer ni à enlever et exigent pour ces opérations de devoir soit déplacer ou soulever la roue du véhicule en cause, ce qui ne permet pas de pouvoir utiliser ces ensembles, en tout temps, au moment opportun où le besoin se fait sentir au cours de l'utilisation du véhicule et de l'enlever lorsque ce besoin est disparu. De plus, les efforts transversaux répétés peuvent provoquer à la longue, un décentrage indésirable de la position de l'ensemble chaînes et chaînons par rapport au centre de la bande de roulement du pneu. D'autres articles sont aussi disponibles mais ils procurent au véhicule une possibilité de déplacement que sur une faible distance en plus des autres inconvénients qui les caractérisent comme par exemple: roulement possible seulement qu'à une vitesse très réduite et dans des conditions inconfortables, traction par à-coups brusques, détérioration des pneus, débalancement dynamique de la roue, conditions d'utilisation engendrant des situations dangereuses, remisage encombrant et dangereux pour les occupants du véhicule, etc. Compte-tenu du fait, que le harnais antidérappant dont il est question présentement peut être posé et enlevé facilement et rapidement de sur n'importe quelle roue d'un véhicule immobilisé sans devoir déplacer cette roue ni la soulever, il est le seul à pouvoir être utilisé en tout temps comme accessoire de dépannage autant pour déprendre un véhicule partiellement enlisé que pour accroître les performances des pneus jusqu'à un niveau nettement supérieur aux performances pouvant être obtenues avec des pneus à neige même ceux munis de crampons métalliques, et ceci, sans égard à la distance à parcourrir. De plus, la conception à trois éléments antidérappants de ce harnais antidérappant procure une stabilité exceptionnelle en résistant aux pires sollicitations de déplacements transversaux aux pneus. Dans plusieurs situations le harnais antidérappant peut remplacer avantageusement l'ensemble chaînes et chaînons.

Abstract: TITLE: BOTTOM HOLE BLOWOUT PREVENTER     INVENTOR:  DONALD H. LINEHAM     ABSTRACT               A  ball  valve  type  bottom  hole  blowout  preventer operates  under  normal  drilling  conditions  in  a  fully  open position with an unrestricted bore.  This operating condition is maintained  by  a  combination  of  spring  and  mud  flow  pressure acting against the upper surfaces of the valve.  In the event of a  well  kick  or  blowout,  pressures  from  gas  or  fluid  volumes acting against the lower surfaces of the valve force it into the fully closed position.  A system of ports and check valves within the blowout preventer forces hydraulic fluid from one chamber to another.  The metering effect of these ports determines the rate of  closure  of the  valve,  thereby  allowing normal  running  and pulling of the drill string or tubing,  without  interference to pipe  fill-up  or  drainage,  from  valve closure.   This  blowout preventer  is placed  in a sub that  is an integral park of  the drill  string  and  can  be  incorporated  in  a  string  in  any location.

Abstract: ABSTRACT OF THE DISCLOSURE       An ink pump for a high speed mailing machine is dis-closed. The ink pump pumps ink from an ink reservoir to an ink pad of an ink pad device.  The ink pump comprises a deformable chamber and valving which cooperate to pump ink upon compression of the chamber and release of the compression.  The pump com-prises an input and an output, and the valving comprises a one way valve, e.g., a duck bill valve, disposed at the pump input which closes upon compression of the chamber and opens upon release of the compression, and a one way valve, e.g., a duck bill valve, disposed at the pump output which opens upon compres-sion of the chamber and closes upon release of the compression.          Duck bill valves enable the pump to be disposed in any attitude including horizontal, and duck bill valves may be disposed entirely within the deformable chamber. In a specific embodiment the deformable chamber comprises a sleeve of elastic material.          According to an embodiment of the invention, an ink pump and an ink pad device including an ink pad are attached so as to form a unit which preferably is disposable.  According to another em-bodiment, an ink pump and an ink reservoir are attached as a unit. According to another embodiment of the invention, an ink pump, an ink pad device including an ink pad, and an ink reser-voir are attached so as to form a unit which preferably is dis-posable.

Abstract: PRESERVATION OF FLOWERS BY LYOPHILIZATION AND VACUUM DEPOSITION                   POLYMERIZATION COATING                ABSTRACT        This invention pertains to the preservation of flowers, and other botanicals for decorative purposes, to a degree that the preserved flower, or other botanical structure, maintains the appearance as if it was still freshly cut.          The method for preserving the material is two-phased.  The first phase is the drying in vacuo, preferably while frozen (lyophilization); and the second phase is the coating of the external surface with a polymerizable monomer which adsorbs from the vapour state and polymerizes after deposition onto the flower's surface.  The flower is effectively encased in the transparent hydrophobic coating and protected from the deleterious effects of ultraviolet light degradation of pigments, from moisture and from mechanical cracking and breaking of the otherwise brittle petals.  The internal water, being removed, cannot now support the normal biochemical degradation of the cellular structures that occurs in non-living plants.

Abstract: RD-19,214 METHOD OF OPTIMIZING PASSIVE SHIM  PLACEMENT IN MAGNETIC RESONANCE            MAGNETS                Abstract of the Disclosure A method of passively shimming a magnet having a central bore using ferromagnetic shims is provided.  The field strength in the bore of the magnet is measured at a predetermined number of points.  The field inhomogeneity is determined from the measured field strengths.  The fields created by a single shim of known size when positioned, at different predetermined positions in the bore of the magnet is determined.  The shim locations in the bore of the magnet and shim size are determined using a linear programming solver to minimize the field inhomogeneity and the total amount of shims used.  The shim sizes are determined based on the measured field in the bore of the magnet and the field created by a single shim when positioned at a predetermined number of locations.  The shim size at the appropriate locations are adjusted to the determined values and the field strength of the magnet is again measured at the predetermined paints.  The inhomogeneity is determined with the shims in place and compared to a desired value of inhomogeneity.  If the inhomogeneity is greater than desired, then shim placement and shim size are again determined, the shims put in place, and the field measured again until the desired inhomogeneity is achieved.
