Patent CA-2241733-A1 (CA)
Title: Corner/post edge protector having improved column compressive strength
Inventor: LOESCHEN MICHAEL D
IPC: B65D81/02
Filed: 1998-06-25
Abstract: A corner post/edge protector structure comprises an apex portion, a pair of leg members disposed substantially perpendicular with respect to each other, and concave/convex transitional regions integrally interconnecting the leg members to opposite ends of the apex portion. The concave/convex transitional regions define axially extending strengthening ribs for enhancing the axial or columnar compressive strength characteristics of the structure when the same is used in conjunction with stacks or tiers of packages, containers, or palletized loads. In addition, the transitional regions permit outer and inner surface portions of the leg members to be coplanar with outer and inner surface portions of the apex portion so as to facilitate or enable compact storage of the containers, packages, or palletized loads within cargo holds and storage facilities. Still further, the transitional regions enable the leg members to undergo resilient flexural movements under impressed packaging strapping loads or forces and facilitate favorable distribution of the strapping loads or forces.

Patent CA-2260725-A1 (CA)
Inventor: NEILL EUGENE BRUCE
IPC: D21F1/06
Filed: 1999-02-04
Abstract: Edge flow control valves located within edge flow tubes of a tube bank in a headbox can be adjusted to optimize fiber orientation of paper produced in a papermaking process. The present invention uses a chamfer at the inlet of edge flow tubes in order to increase maximum flow of pulp through the edge tube and edge valve. The minimum flow range is not changed, therefore, the essential flow range of pulp through the edge flow valve is increased. Laboratory tests have shown at least a 15 percent increase in maximum flow while not changing the minimum flow. Using a chamfer tool with a stop collar to control the depth of the cut, a chamfer is provided at the inlet of each edge flow tube for optimum performance.      According to the present invention, paper produced in a papermaking process will have an improved fiber orientation when more flow at the edges of a headbox is needed.
Patent CA-2262220-A1 (CA)
Title: Electronically controllable limited slip differential
Inventor: LEEPER ROBERT
IPC: F16H48/34
Filed: 1999-02-15
Abstract: A controllable differential having a clutch mechanism which transfers a predetermined amount of torque between a rotatable differential casing and a side gear when an initiating force is applied by an electronic actuator. The clutch mechanism comprises a cone clutch element having a frustoconical engagement surface and an insert having a complementary frustoconical engagement surface disposed between the side gear and the rotatable casing. The clutch mechanism further includes a pair of biasing elements which urge disengagement of the frustoconical engagement surfaces and resist axial movement of the cone clutch element and the insert. The cone clutch element and the side gear also include caroming portions having ramp surfaces which ride-up on each other and provide further axial separation forces when the clutch mechanism is actuated. Alternatively, a ball and ramp arrangement may be used to provide this axial separation. The clutch mechanism is actuated by an electromagnet which applies an initiating force to the cone clutch mechanism to initially move the cone clutch element when a predetermined relative rotational condition of the side gear is sensed. The application of the initiating force in combination with the interaction between the frustoconical engagement surfaces and between the caroming portions fully engages the clutch mechanism to transfer a predetermined controllable amount to torque. The present invention also provides a differential having a camming element disposed between a first clutch and a first side gear, the camming element has first and second caroming portions coupling the camming element to each of the first clutch and first side gear, adapted to couple them together. An electromagnet of variable strength urges the first clutch into engagement with an interior surface of the casing. Relative rotation between the caroming element and the first side gear induces axial separation therebetween, urging a second clutch attached to a second side gear in abutting communication with the first side gear, into engagement with another interior surface of the casing. The axial force exerted on the second clutch by the camming element through the first and second side gears may be a fixed multiple of the axial force acting between the first clutch and the camming element. The rotatable casing of the present invention may include a nonmagnetic portion attached thereto, about which the toroidal magnetic flux path of the adjacent electromagnet may be directed for actuating the clutch.
Patent CA-2264491-A1 (CA)
Inventor: PUENJER RALF
IPC: B21D45/00
Filed: 1999-03-04
Abstract: A method and a device for removal of a slug separated from a hollow profile by means of a fluidic internal pressure from a hydroforming tool. The slug is separated from the hollow profile from the inside to the outside by the retraction of a plunger integrated into the hydroforming tool and clearing a slug channel when retracted, and is forced out of the die cavity of the hydroforming tool into the slug channel. Then, with the hollow profile in a zero-pressure state, the slug, which after it is pressed in abuts the end of the plunger, is removed by a removal tool from the hydroforming tool. In order to remove slugs from the hydroforming tool in any desired position of the slug channel that leads into the die of the hydroforming tool, in which the slug is initially received after perforation, in simple fashion, the slug is held at the end of the plunger during its stay in the slug channel by an adhesion means connected with the plunger. Then, after the hydroforming tool is opened and the finished hollow profile is removed, the slug, while continuing to adhere to the end of the plunger, is guided by means of the plunger and of the removal tool designed with adhesion means into the open die cavity. The slug and the area of the removal tool on which the adhesion means acts assume a relative position opposite one another, after which the slug is separated from the plunger and then adheres to the removal tool, by means of which the adhering slug is then removed from the hydroforming tool.

Title: Method for corneal laser surgery
Inventor: JUHASZ TIBOR
IPC: A61F9/01
Filed: 1999-03-31
Abstract: A method for corneal laser surgery includes directing the focal point of a focused laser beam at a start point in the stroma. The focal point is then moved along a predetermined path (92) in the cornea to photo disrupt tissue, and to create a flap or a plug of corneal tissue. Specifically, the flap or plug (72) is crated with an undercut region (74) that interlocks with an overlay region (76) to restrain movement of the flap or plug in an anterior direction. Stromal tissue under the flap or plug can then be, removed (36) when the plug or flap is forcibly lifted from the cornea. The flap or plug is subsequently replaced in its interlocking relationship with the remainder of the cornea tissue. The diminished stromal tissue reshapes the cornea in a manner which improves the vision of the patient.

Patent CA-2272474-A1 (CA)
Inventor: MILNE CHRISTOPHER G
IPC: A61K9/127
Filed: 1997-11-24
Abstract: The present invention relates generally to the method for the production of liposomal microencapsulated boron-containing products to be used for agricultural formulations. More specifically, a new method of production of liposomal microencapsulated is disclosed for active agents such as pesticides.  A lecithin is mixed with an organic solvent in a certain proportion so as to provide solutions with varied levels of solubilized lecithin. The particular solvent being used will depend on the amount of active agent (AA) desired in the final solution. The formulation of the lecithin/organic solvent mixture is then allowed to settle. After settling, the top layer is separated and saved, while the bottom layer is discarded. An AA is then added to form a concentrate that is added to water for vesicle formation. Boron-containing materials formulated according to the invention may now be applied to agricultural field crops and fruit.
