Abstract: Lithographic printing constructions and methods of imaging them[ are disclosed]. The constructions include a grained-metal substrate, a protective layer that can also serve as an adhesion-promoting primer, and an ablatable oleophilic surface layer. In operation, imagewise pulses from an imaging laser interact with the surface layer, causing ablation thereof and, probably, inflicting some damage to the underlying protective layer as well.

Title: Measurement referencing and transferring instrument
Inventor: ROMINE MICHAEL LEE
IPC: G01C15/00
Filed: 1995-12-06
Granted: 2001-05-15
Abstract: A measurement referencing and transferring technique includes locating a platform base at a working location, mounting a sighting mechanism having a sighting axis on the platform base, and sighting a selected point on a first object in a given direction from the platform base by adjusting the position of the platform base relative to the working location, thereby directing the sighting axis of the sighting mechanism toward the first object, and aligning the axis incident with the selected point on the first object.  A reference point is marked on a second object in a direction opposite the given direction from the platform base, by observing along the aligned sighting axis in the direction away from the first object, and defining the reference point as that point on the second object with which the sighting axis is incident.  A measurement associated with the selected point on the first object is determined by referring to the reference point marked on the second object.

Patent CA-2168486-C (CA)
Title: Particle agglomeration and precipitation from a gaseous stream
Inventor: DULLIEN FRANCIS A L
IPC: B01D45/08
Filed: 1996-01-31
Granted: 2001-04-17
Abstract: The performance of a precipitator for separating liquid or solid particles suspended in a gaseous stream is improved when the particles are fine or ultra-fine, e.g. submicron, by treating the stream before it enters the precipitator to agglomerate the fine particles into larger ones.  This result is achieved by passing the stream successively through a series of screens.  Some particles entrained in the stream impact on solid portions of each screen, and become agglomerated in the process.  Subsequently, a large portion of the agglomerated particles are re-entrained in the stream and pass to the precipitator.  Since only a small percentage of the particles impacts each screen, a relatively large number of screens is normally preferred, e.g. at least 30.  An improved form of precipitator employs pleated sheets to form the surfaces on which the particles are collected.
Patent CA-2171787-C (CA)
Title: Protective intraluminal sheath
Inventor: ANDERSON SCOTT C
IPC: A61M25/08
Filed: 1996-03-14
Granted: 2007-05-15
Abstract: A sheath holds a device against a balloon catheter for delivery in the lumen of a patient. The device can be a stent and graft combination. The stent is kept properly centered over the balloon catheter by the sheath as the graft is placed in a blood vessel. The smooth outer surface of the sheath protects the vessel wall from the rough surface of the stent. A notch is formed in the end of the sheath where the free end of a strand of thread protrudes from the sheath. The sheath is removed from the graft by pulling on the free end of the strand otherwise located distally from the outer surface of the sheath. The strand cuts through and splits open the sheath as a result of the force applied on the free end of the strand. The other end of the strand is attached to a reinforced collar at the other end of the sheath. The strand does not cut through the collar. After reaching the collar, the proximal force applied on the strand now pulls the split sheath from the stent-and-graft combination without disturbing the placement of the stent over the balloon delivery catheter.

Title: Composite fiber rotor vane
Inventor: MURCHING NAGENDRA N
IPC: B29C43/02
Filed: 1996-03-27
Granted: 1999-02-16
Abstract: A rotor vane and a method for fabricating the rotor vane are provided in which the vane is formed of a thermoplastic matrix material having chopped fibers uniformly dispersed throughout the thermoplastic material, with the fibers aligned to extend in directions which are approximately parallel to a radial dimension in which the vane extends.  A billet formed of the thermoplastic matrix material with the chopped fibers randomly oriented and uniformly dispersed within the thermoplastic matrix material is placed in vane forming dies.  The dies have an interior surface which is in the shape of the vane.  The billet is placed within the dies with the longitudinal length of the billet extending perpendicular to the radial dimension of the vane being formed and completely across the axial dimension of the vane being formed.   The billet is heated to a softening temperature and compressed within the dies to deform the billet into the shape of the interior surface of the dies, causing the thermoplastic matrix  material to  flow  in  flow  directions  which  are approximately parallel to radial dimension of the vane being formed.  Flowing of the thermoplastic matrix material in the flow directions aligns a substantial portion of the fibers with the flow directions, approximately parallel to the radial dimension of the vane.  Then the thermoplastic matrix material is cooled to temperature below the softening temperature and the vane is removed from the dies.

Abstract: A shuttering panel (1) has edge struts (3) formed from a flat extruded section made of aluminium, an aluminium alloy or another light metal, ensuring both lightness and rigidity. The contact points for clamps (7) for the mutual securing of such edge struts (3) of adjacent shuttering panels (1) are at a distance from the shuttering lining (2) at a site where the edge struts (3) have a solid cross section and the hollow spaces (8) on either side of this contact point are not at risk of being deformed by the pressure exerted by the fixing clamps (7). A groove (14) or channel is provided with which the clamp can engage to ensure that this contact point is actually used. This makes it possible to use the same clamp (7) which serves for edge struts made of flat material with a central bead so that shuttering panels made of different materials and provided with such edge struts can be combined.
