Patent CA-2182719-A1 (CA)
Title: Friction Stir Welding
Inventor: MIDLING OLE TERJE
IPC: B29C65/06
Filed: 1995-01-05
Abstract: An improved method of friction stir welding is based on enhanced flow of plaslicised material both perpendicularly and vertically to the longitudinal extension of the adjacent assembled members by exposing the created plasticised material to a perpendicular pressure along the surface of the members and causing simultaneous material flow along the probe pin in the vertical direction allowing the plasticised material to solidify behind the probe. A non-consumable probe (1) is provided comprising a concave bottom part (23) with an interchangeable pin (24) having surface of threaded configuration and in a preferred embodiment comprising two or more laterally protruding blades.

Inventor: CARDUCCI ROBERT F
IPC: B64D9/00
Filed: 1996-02-01
Abstract: Système permettant de transformer tout ou partie d'une cabine passagers prévue dans le fuselage (1) d'un avion pour transporter du fret. La cabine comporte des parois longitudinales et un plafond aménagés à l'intérieur (8, ...) définissant un profil transversal interne de section sensiblement uniforme. Ledit système comporte une structure de garniture rigide démontable qui forme une enceinte dont le profil extérieur se loge dans un espace intérieur de la cabine sans toucher les parois ni le plafond. Ladite structure est formée d'éléments verrouillables (22, ...) dont chacun est assez petit pour passer par une porte (14) de soute ménagée dans le fuselage et est supportée entre les extrémités de la cabine par les seuls ancrages déblocables qui bloquent les rails de fixation des fauteuils installés dans la cabine, la structure de garniture incluant des dispositifs transversaux de retenue de fret qui y sont fixés de manière amovible pour empêcher le déplacement du fret dans cette dernière. Les modules forment une série de compartiments reliés longitudinalement, chaque compartiment comportant un treillis et des ancrages pour fixer un dispositif de retenue de fret à son extrémité avant, un compartiment situé tout à la fin étant fermé à une extrémité de la structure par une cloison de séparation de cabine ou une structure (100) de remplacement de cloison de séparation reliée au fuselage de l'avion à la place d'une cloison de séparation de cabine amovible, et qui peut communiquer avec une soute à bagages (6, 6a). Les éléments de l'enceinte sont scellés les uns aux autres ainsi qu'au plancher de la cabine et à la structure de cloison de séparation, afin d'isoler ladite enceinte de la cabine dans laquelle elle est installée et de s'opposer au passage de fumée, de vapeurs ou de flammes de l'enceinte à la cabine.

Title: Die coating method and apparatus
Inventor: BROWN OMAR D
IPC: B05C11/04
Filed: 1995-03-16
Abstract: A die coating method and apparatus includes a die (40) having an upstream bar (64) with an upstream lip (60) and a downstream bar (66) with a downstream lip (62). The upstream lip (60) is formed as a land (68) and the downstream lip (62) is formed as a sharp edge (70). The shape of the land conforms to the shape of the surface being coated. Changing at least one of the slot height H, the overbite O and the convergence C can improve coating performance. A replaceable, flexible strip (350) can be used above the coating slot to facilitate replacement of a damaged overbite edge. A low surface energy coating can be applied to the downstream bar and land surfaces.

Patent CA-2192986-A1 (CA)
Title: Autofocus system for scanning microscopy
Inventor: PRICE JEFFREY H
IPC: G02B7/36
Filed: 1995-06-30
Abstract: Reliable autofocus is required to obtain accurate measurements of fluorescent stained cellular components from a system capable of scanning multiple microscope fields. Autofocus could be performed directly with fluorescence images, but due to photobleaching and destructive fluorescence by-products, it is best to minimize fluorescence exposure for photosensitive specimens and live cells. This exposure problem could be completely avoided by using phase-contrast microscopy, implemented through the same optics as fluorescence microscopy. Functions for both phase-contrast and fluorescence autofocus were evaluated using the present invention and the suitability of phase-contrast autofocus for fluorescence microscopy was determined. The present autofocus system for scanning microscopy can be performed at least as fast as 0.25 s/field without loss of precision. The speed of autofocus can be further increased by a volume image which is obtained by observing an image object at each image plane of a plurality of image planes, where each image plane is vertically displaced with respect to each other image plane. An electronic image representation is obtained at each image plane. The image planes are scanned over the image object and the images are aligned timewise in a buffer. The buffer holds a volume image comprising images at the image planes, aligned by the buffer. The image plane having the but focus is selected and a microscope objective is automatically positioned at the selected plane.

Title: Injection molding nozzle heater clamp
Inventor: BECK JOHN P
IPC: B29C45/17
Filed: 1995-06-27
Abstract: A heater assembly (14) clamps onto cylindrical bodies (12) such as injection molding nozzles (12) that require heating. A mandrel (16, 61) slips over the nozzle (12), and has a heater (24, 68) wound on the exterior. The mandrel (16, 61) has a longitudinal slit (32, 65) that will permit the bore of the mandrel (16, 61) to be reduced in size when a lateral width of the slit (32, 65) is reduced. The mandrel (16, 61) carries outwardly facing cam surfaces (20A, 21, 63A, 67), and an overlying sleeve (30, 70) has inwardly facing cam surfaces (36A, 40A, 71A, 72A) which mate, and upon relative longitudinal movement, the cam surfaces (36A, 40A, 71A, 72A) cause the lateral width of the slit (32, 65) to reduce and clamp the mandrel (16, 61) onto the nozzle (12). The clamping can be effected by differential movement due to differences in thermal expansion of the mandrel (16) and the sleeve (30), or by mechanical movement of the sleeve (70) relative to the mandrel (61) to obtain the cam action.

Title: Portable collapsible shelters
Inventor: ELSINGER RAYMOND A
IPC: E04H15/48
Filed: 1997-01-03
Abstract: A portable collapsible shelter comprises a floor, pairs of corner posts, a horizontal brace extending between and pivotally attached to the corner posts of each pair, and built-in seats.  The floor, corner posts, braces, and seats are foldable between respective erected and collapsed modes.  In the collapsed mode, each corner post is folded into a stack, with the stacks of each pair thereof being coplanar.  The associated brace is initially at the top of the stacks of folded corner posts.  The brace folds into a stack located coplanar with and between the stacks of the associated corner posts when the floor is folded to its collapsed mode.  The seats fold with the corner posts and lie on the floor when the corner posts are folded to their collapsed mode.  Locking devices selectively prevent and enable folding of the floor, corner posts, and braces.

Title: Process for peeling off temporarily protecting coating film
Inventor: TOJO HIDEAKI
IPC: B08B3/02
Filed: 1997-01-09
Abstract: In peeling off, from a coating surface, temporarily protecting coating films formed by applying a protecting coating material onto the coating surface after completion of the coating, high-pressure water is jetted toward between the coating surface and end edges of the temporarily protecting coating films to peel off the end edges from the coating surface.      Then, the high-pressure water is jetted sequentially to between the coating surface and peeled-off portions of the temporarily protecting coating films from the coating surface to peel off the entire temporarily protecting coating films from the coating surface. Thus, the temporarily protecting coating films can be easily peeled off without being influenced by the temperature of an environment, leading to a shortened peeling-off time.

Title: Hybrid fiber-coax system having at least one digital fiber node and increased upstream and downstream bandwidth
Inventor: DAIL JAMES E
IPC: H04N7/173
Filed: 1997-05-13
Abstract: Noise is reduced and bandwidth may be increased in a CATV transmission system by modulating a portion of subscriber-generated upstream signals to a  high frequency band (e.g., 750-100 MHz) and then digitally regenerating such sign als. To further reduce noise, the digitally regenerated upstream signals are transmi tted by in a baseband digital format to the head end (120) via a digital E/O converter (3 30). Increased downstream bandwidth is obtained by modulating a portion of the downstream s ignals to a higher frequency band (e.g., 500-750 MHz) and then digitally regenerating such signals.
