Patent CA-2049575-C (CA)
Title: Stretching machine
Inventor: YAZAWA HIROSHI
IPC: B29C55/16
Filed: 1991-08-20
Granted: 1997-10-14
Abstract: A pair of stretching pulleys are rotatably mounted on a pair of support plates within-a housing.  A belt is wound around the upper part of the stretching pulley and a number of turn pulleys.  A film introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred.  Air flow generated by a fan and heated with a heater is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan.  The stretching pulley is partially cooled in a water bath.         The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates.  The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.

Abstract: L'invention porte sur un dispositif de suspension destiné à un tuyau ou à un flexible de transport de pétrole servant au chargement et au déchargement d'un navire.  Le dispositif est de type cardan.  Pendant le déchargement, le pétrole est acheminé vers le centre du cardan depuis un seul ou deux côtés le long de l'axe horizontal par l'intermédiaire d'un ou de plusieurs joints articulés et peut-être aussi de paliers.  Le pétrole est ensuite détourné et réacheminé vers le centre du cardan en suivant le second axe de ce dernier.  Après avoir passé le joint articulé suivant, le pétrole est réorienté selon le troisième axe du cardan.  Pour libérer les contraintes s'exerçant sur ce joint, des paliers peuvent être montés coaxialement avec ce dernier.  Dans ce cas, le coude du tuyau est suspendu dans des supports attachés à une cellule de charge cylindrique qui, elle-même, pivote dans une poutre faisant partie intégrante du dispositif de suspension et pivotant dans le premier axe du cardan.  La cellule de charge peut enregistrer la traction sur le flexible.

Abstract: An insulating spacer creates a thermally insulating bridge between inner and outer panes of, for example, a multiple pane window unit. The spacer defines an insulated space between the panes and includes a top bridge member, first and second leg members, a bottom bridge member and a channel portion. The top bridge member contacts the inner and outer panes of the window unit. The top bridge member is made of a synthetic resin or composite material and can include openings. The first and second leg members are embedded by crosshead extrusion into the top bridge member. The first and second leg members can be bent into a zig-zag configuration. The bottom bridge member is substantially parallel to the top bridge member. The channel portion is defined by the configuration of the top bridge member, the first and second leg members and the bottom bridge member. In one embodiment, the bottom bridge member is roll-formed from the same piece of material as the first and second leg members. In another embodiment, the bottom bridge member is formed from a material similar to, or the same as, that of the top bridge member. Methods of making the insulating spacer of the present invention also are disclosed.

Title: Analyzing heart wall motion using spatial modulation of magnetization
Inventor: AXEL LEON
IPC: G01R33/563
Filed: 1991-08-19
Granted: 2001-11-20
Abstract: A technique for generating "optimal" radio frequency pulses for use in creating SPAMM imaging stripes and for quantitatively de-termining the displacements of the imaging stripes during a pre-imag-ing interval. The imaging operator selects the desired stripe parame-ters (304) so that the resulting SPAMM imaging stripe will have the desired narrowness, sharpness, flatness and the like. These parame-ters are then used by an optimal pulse generating system (212) to gen-erate the input radio frequency pulse sequence which will produce the desired stripes. Tagging of the heart wall or some other soft tissue structure with a grid of planes of altered magnetization is then used to provide finite element analysis to quantify regional heart wall motion and the like. The intersections of the tagging stripes are used as a set of fiducial marks within the heart wall, and the motion of these inter-sections through the heart cycle is used to track the motion of the un-derlying tissue.

Abstract: A non-ferrous matte conversion process is disclosed in which molten non-ferrous matte, essentially nickel and/or copper sulfide and iron sulfide, isprovided in a suitable vessel, such as a modified Pierce-Smith converter. The bath is stirred from below with a non-reactive sparging gas, such as nitrogen, and surface-blown from above with an oxygen-containing gas. A flux is added to the melt to raise a fluid slag. In addition, cold crushed matte is added to the bath. The cold matte acts to maintain the temperature of the bath, so as to prevent overheatingwhich can damage the converter lining. The matte addition also serves as a source for additional converter feed. As the reaction progresses, the slag layer is periodically skimmed, and additions of flux and cold matte are made when necessary. When it is no longer possible to raise a slag, a non-ferrous sulfide matte is obtained having a greatly reduced iron content.
