Title: Motor having universal fan end bracket
Inventor: GILLILAND MICHAEL L
IPC: H02K9/04
Filed: 1997-08-19
Abstract: A fan end bracket for a motorized fan assembly has a plurality of curvilinear tapered air passages. Each air passage includes a flow port, such that air being moved by a rotating fan assembly is directed through the air passages and the flow ports. A skeletal motor assembly is affixed to one side of the end bracket such that the motor shaft is disposed through a shaft aperture in the end bracket. A rotating fan member is affixed to the motor shaft adjacent to the other side of the end bracket. A  shroud member is provided to shroud the rotating fan member so as to cause the flow of air to be directed through the air passages. A baffle plate is interposed between the rotating fan member and the end bracket. The baffle plate includes a plurality of curvilinear scallops which correspond to the air passages in the end bracket. An effective flow port is created between the scallops of the baffle plate and the tapered ramp surfaces of the end brackets so the size of the effective flow port may be adjusted by merely changing the baffle plate so as to optimize the flow and pressure parameters of the fan for a particular motor size.

Title: Machine clothing having a seam, and spiral for use in such a seam
Inventor: FAGERHOLM LARS
IPC: D21F7/10
Filed: 1996-03-25
Abstract: The invention relates in general to an improvement of a spiral (20) for producing an enhanced seam on a machine clothing for a paper or cellulose machine, especially, but not exclusively, when using flat filament yarns (26) in the machine direction of the clothing. The seam has two preformed yarn spirals (20), which are each bound, by the machine direction yarns (26) of the clothing, to one seam edge, thereby each forming a row of seam loops (22) which are meshable with each other and joinable onto each other by means of a pintle wire. At least one spiral (20), preferably both, is, between neighbouring seam loops (22) in the row of loops, preformed with special securing portions (24), to which the spiral (20) is attached at the corresponding seam edge. The securing portions (24) hold the seam loops (22) spaced apart and are extended substantially in the longitudinal direction of the spiral (20).

IPC: C08G18/70
Filed: 1997-10-30
Abstract: This invention relates to mixtures of polymethylene~ poly(phenyl-isocyanate) blends with epoxides.

Patent CA-2220901-A1 (CA)
Inventor: HAYES WILLIAM A
IPC: H01M8/24
Filed: 1996-05-17
Abstract: L'invention porte sur les empilements de piles à combustibles (1) constituées de plusieurs piles comprenant chacune une série de plaques collectrices mono et bipolaires (BSP) en relation mutuelle, construites, quant à elles, par stratification d'un noyau de lamelles apparentées non conductrices en céramique ou en plastique (12), en sandwich entre des lamelles de microtamis conductrices, en métal ou en céramique ou en plastique conducteurs, une membrane électrode (EMA) (5, A, B, C, D) se trouvant entre des BSP contiguës. Les lamelles, tant métalliques que plastiques des BSP composites sont obtenues à partir de feuilles comportant des motifs à traversées et à creux en profondeur (18, 17) formés par attaque, passage à la presse, matriçage, coulée, emboutissage et processus similaires. Les plaques contiguës, chacune avec des motifs évidés en regard, définissent des canaux en forme de serpentins à l'intérieur de l'empilement lamelles/piles monolithique résultant, permettant une gestion intégrée des fluides et des températures. Les lamelles plastiques s'avèrent des plus utiles dans le cadre de piles à combustibles à membrane échangeuse de protons utilisant de l'hydrogène et de l'air/oxygène comme combustible. Les lamelles sont aisées à fabriquer par des procédé d'impression (emboutissage) tandis que les matrices sont obtenues par attaque photolithographique permettant un rapide remaniement. Il est possible d'adapter chaque BSP à chaque type de membrane, de combustible et de positionnement à l'intérieur d'une pile dans l'empilement (1). Dans la mesure où les matériaux utilisés sont peu coûteux et faciles à produire comme à assembler, il est possible de réaliser des piles à combustible légères et de puissance volumique élevée. Leur application industrielle s'étend à des approvisionnements en énergie, fixes et mobiles, microscopiques comme macroscopiques.

Patent CA-2233874-A1 (CA)
Inventor: SHERWOOD GREGORY J
IPC: C09K5/04
Filed: 1996-10-15
Abstract: L'invention concerne un procédé et un dispositif pour l'utilisation de certains hydrofluoroéthers comme milieux d'échange thermique à basse température dans les systèmes de réfrigération à boucle secondaire. Ces hydrofluoroéthers présentent un facteur de différence de température peu élevé et quelque peu linéaire dans la plage de températures comprises entre -15 ·C et -65 ·C et se prêtent donc parfaitement bien à une utilisation comme milieux d'échange thermique à basse température. Ils sont innanflammables, non toxiques, inoffensifs pour l'environnement, et ont par ailleurs une capacité d'échange thermique élevée et une faible viscosité dans la plage requise de températures de fonctionnement. De plus du fait qu'ils présentent un point d'ébullition élevé et un faible point de congélation, ces hydrofluoroéthers ne sont pas susceptibles de changer de phase dans les plages de températures de fonctionnement requises et ne nécessitent pas l'utilisation de systèmes sous pression.

Title: Plastic nut for connecting panel-like parts
Inventor: KONIG GOTTFRIED
IPC: F16B12/26
Filed: 1997-08-27
Abstract: A plastic nut for inserting into a through hole of a plate-like element consists of holding parts of which one is designed as a flange that can be pressed on the element from the mounting side and another is designed as a snap-in hook that can be pressed from the opposite side for locking into place behind the element. The holding parts are provided with a nut part with a bore for receiving a screw. The flange is part of a flange part that includes the nut part and the nut part can be pressed in the direction of the flange. The nut part can be axially pressed towards the flange part in relation to the flange part by an elastic supporting arrangement that forms a resilient zone.  The resilient zone brings the nut part and the flange part to bear on the element after the plastic nut is inserted, compensating for different thicknesses of the element.

Title: System and method of petrophysical formation evaluation in heterogeneous formations
Inventor: EKSTROM MICHAEL P
IPC: G01V11/00
Filed: 1997-01-16
Abstract: A system and method for evaluating a geological formation is described which compares actual wireline log measurements from a number of wireline logging tools to predicted tool response logs. The system and method uses a forward model of each tool response, given a formation description, to predict a set of wireline logs. Comparing the predicted logs with the actual measured logs yields a mismatch error. The system and method iteratively adjusts the formation description to minimize the mismatch error to obtain a "best"  formation description. In one form, the formation description includes petrophysical properties (porosity, density, saturation) and geometry properties (dip, bedding, invasion). In a more complicated form, the formation description also includes a model of petrophysical mixing laws and formation material content. In the special case of a horizontally layered formation and linear tool response models, there exits a computationally efficient version of the system and method.
