Inventor: RAO V DURGA NAGESWAR
IPC: C23C4/10
Filed: 1995-11-30
Abstract: A method of making an engine block with coated cylinder bore walls by: (a) casting the engine block of metal (primarily a low cost aluminum alloy such as 319 grade),  (b) removing contaminants from the cast cylinder bore walls to provide at least one annular cleansed fresh metal surface,  (c) depositing a plasma sprayed coating onto the surface with a powder mixture containing solid lubricant particles that provide a dry coefficient of friction of .3 or less,  (d) shaping such coating to be concentric about the true axis of said cylinder bore walls, and (e) honing the coating to final finish smoothness. Exposing fresh metal (removal of any metal oxide) can be carried out by grit (shot) blasting, electric discharge erosion, mechanical machining of serrations, or by plasma etching.  Concentric shaping may be carried out either by rough machining the cylinder bore walls followed by deposition of the thinnest coating that requires only finish honing, or by deposition of a thicker coating followed by rough honing of the coating to concentricity.

Patent CA-2169585-A1 (CA)
Title: Concrete cladding panel system
Inventor: KUELKER PETER
IPC: B28B23/00
Filed: 1996-02-15
Abstract: A cladding panel system comprises concrete panels having bevelled side edges, such that when the panels are installed on a supporting wall, the bevelled edges of adjacent panels form a V-joint with its apex at the rear surfaces of the panels. The bevelled edges of adjacent panels provide a localized crush zone that absorbs thermal expansion stresses without significant damage to the panels, thus eliminating the need for expansion joints. Flexible grout such as urethane caulking is applied in the V joints between the panels to prevent entry of water. The panels are formed with perimeter caulking grooves to facilitate application of the flexible grout. The grout may have a coating such as silica sand for protection against ultraviolet radiation. Each panel includes hangar means, which may comprise one or more hangers embedded in the panel, for securing the panel to the supporting wall using screws or other common fasteners.

Patent CA-2182515-A1 (CA)
Inventor: BECKER THOMAS P
IPC: B25B23/14
Filed: 1995-11-29
Abstract: A torque-angle wrench (100) is pro-vided with a handle (104) for applying torque, such as to a fastener or bolt, through a tightening angle, at a rotational angular velocity. A piezoelectric gyro-scopic sensor device (102) including cir-cuitry for vibrating an oscillating body is coupled to the wrench. As the wrench is rotated through the tightening angle, its rotational angular velocity causes the vi-brating body to alter its direction of vibra-tion. The new vibrating pattern is sensed and converted, by appropriate sensing cir-cuitry, into an electrical signal proportional in intensity to the rotational angular veloc-ity of the wrench. The electrical signal can be electronically processed by appropriate conversion and display circuitry to provide a visual indication of the tightening angle. Such conversion and display circuitry can be integral with the wrench or as part of an adaptably coupled meter non-integrally connected to the sensor device.

Abstract: Des conditions de cultures cellulaires ont été développées pour maintenir les cellules nerveuses de la rétine dans des conditions bien définies, sans sérum. Les facteurs moléculaires qui stimulent la régénération axonale à partir de ces neurones ont été caractérisés. Les cellules des gaines gliales qui entourent les axones du nerf optique libèrent deux molécules qui déclenchent et favorisent la régénération nerveuse. L'une des molécules, désignée sous le nom de facteur d'axogénèse 1 (AF-1), est un polypeptide de faible poids moléculaire, dont la taille est de l'ordre de 1000 daltons (déterminée par spectrométrie de masse, elle s'élève à environ 700 daltons). La seconde molécule, AF-2 est une protéine de taille plus importante, de l'ordre de 12000 daltons. Des études indiquent que ces facteurs sont fortement impliqués dans la régénération du système nerveux central et peuvent donc être utilisés dans le traitement des lésions de la moelle épinière et d'autres tissus nerveux.

Title: Undercut excavation with protection against seismic events or excessive ground movement
Inventor: GRYBA CHARLES M
IPC: E02D17/00
Filed: 1997-04-16
Abstract: An undercut excavation method is provided, which is particularly suitable as an undercut-and-fill mining method, wherein concrete posts are inserted into holes drilled in the ground and are used to support a concrete floor poured on their top ends, which serves as a roof for the lower excavation level. The bottom ends of these posts rest on resilient elements to provide protection against seismic events or excessive ground movements. Excavation beneath such roof is thereby safely carried out in areas prone to seismic events such as rock bursts or earth quakes or to excessive ground movements. The concrete posts may be attached to the resilient elements at their bottom ends, thereby producing yielding posts suitable for such excavation. For still greater safety, a double post system may be used, which involves placing a second post beside the first after excavation on a given level and tying them all together with the concrete used to make the floor/roof for the next lower level of excavation. In mining this is called double-post mining or DPM.
Patent CA-2204150-A1 (CA)
Inventor: PETERSON ROBERT JAMES
IPC: B29L23/18
Filed: 1995-10-27
Abstract: A method for stripping an open ended bellows part from an injection mold has as a first step the injection molding of a bellows part. The bellows part has a resilient portion located between a core pin (28) and a first split cavity (30) and a substantially rigid portion located between the core pin (28) and a second cavity (44). The substantially rigid portion has a first open end (46) and an external undercut portion (48), and the resilient portion of the bellows part has an inner surface and a second open end (50). The first split cavity (30) opens laterally to permit the resilient portion of the bellows part to be stripped from the core pin (28). Compressed gas passes through the core pin (28) to the inner surface of the resilient portion of the bellows part while both open ends of the bellows part are closed off by the second cavity (44) and the core pin (28). As the cavity and core portions of the mold separate, the second cavity (44) grips the undercut portion (48) of the substantially rigid portion of the bellows part, thereby pulling the resilient portion of the bellows from the core pin (28) while compressed gas maintains the resilient portion expanded. Finally, the second cavity (44) either opens or has a stripper rod (54) to disengage the undercut portion (48) of the substantially rigid portion of the bellows part so that the bellows part may be ejected from the injection mold.
