Patent number: 7028744Abstract: A method of modifying a surface of a casting involves providing a casting mould; placing a perforated mask with the mould to define a masked area of the mould; spray-coating the masked area of the mould with a coating material selected for forming a surface layer on the casting; introducing a liquid casting material to the mould; and, solidifying the liquid casting material to form a surface modified casting. The present method reduces the tendency for the coating material to spall from the mould and permits the formation of thicker coating layers on the mould. Thicker and better quality surface layers may be formed on castings.Type: GrantFiled: March 17, 2004Date of Patent: April 18, 2006Assignee: National Research Council of CanadaInventors: Jiaren Jiang, Xing Yang Liu

Patent number: 7020915Abstract: A hammock has a bed formed from a blank of flexible fabric. The blank is defined by opposed ends and opposed sides, the ends and sides of the blank coinciding with opposed ends and opposed side edges of the hammock respectively. Each side of the blank tapers inwardly from the ends, each end of the blank has a notch having opposed edges of equal length. The opposed edges of each notch taper inwardly from the end towards an apex. The opposed edges of each notch are attached by a seam to form the bed from the blank. Cross-braces proximal the ends of the hammock are connected to the side edges of the hammock at connection points opposed across the bed from one side edge to the opposite side edge. The fabric hangs underneath the cross-braces so that an occupant may rest level on the bed fully under the cross-braces. The hammock is suspended between upright structures, such as trees or posts, using a special connection involving a cargo hook having a hook portion and a ring portion.Type: GrantFiled: May 20, 2005Date of Patent: April 4, 2006Inventor: David Helsdon

Patent number: 6926066Abstract: An improved magnesium die casting system incorporates filling of the shot sleeve from the underside and/or in-line re-melting of scrap magnesium using a re-melt furnace. A pump is used to transfer molten magnesium from a casting furnace to the shot sleeve through an underflow filling tube. The shot sleeve is filled in a laminar manner, minimizing entrapped gases. The in-line re-melt system allows recycling of scrap in-house and reduces energy cost associated with heating and re-heating scrap. The improved system increases casting quality and reduces scrap rates and recycling costs.Type: GrantFiled: November 13, 2003Date of Patent: August 9, 2005Inventor: Alain Renaud Boulet

Patent number: 6864190Abstract: Disclosed is a process for fabricating luminescent porous material, the process comprising pre-treating a substrate (e.g. crystalline silicon) with laser radiation (e.g from a Nd:YAG laser) in a predetermined pattern followed by exposing the irradiated substrate to a chemical stain etchant (e.g. HF:HNO3:H2O) to produce a luminescent nanoporous material. Luminescent porous material having a luminescence maximum greater than about 2100 meV may be produced by this method. Such nanoporous materials are useful in optoelectronic and other semiconductor devices.Type: GrantFiled: October 17, 2002Date of Patent: March 8, 2005Assignee: National Research Council of CanadaInventors: Yujie Han, Suwas Nikumb, Ben Li Luan, John Nagata

Patent number: 6863062Abstract: A masonry cutter comprising a tripod having legs for straddling the masonry to be cut and a cutting assembly mounted between the legs. The cutting assembly comprises a cutting element, preferably a circular saw, and a means for operating the cutting element. The legs may be vertically adjustable. Adjustment of the legs permits changing the angle between a plane parallel to the cutting element and a plane parallel with the masonry to be cut. The tripod may be mounted to a frame by means of a pivot with a vertical pivot axis passing through the pivot. This allows the tripod legs to be positioned and the cutting assembly to be oriented so that the first and second axes are in a desired direction with reference to the masonry to be cut. In one embodiment, the masonry to be cut is a sidewalk slab and the apparatus is used to remove trip hazards from the sidewalk slab. The masonry cutter may be removably mounted to a vehicle.Type: GrantFiled: April 3, 2003Date of Patent: March 8, 2005Assignee: Sidewalks Plus Inc.Inventor: Leo Edmund Denys

Patent number: 6854949Abstract: A refuse collection vehicle having a vehicle chassis including a vehicle cab and frame with a vehicle body mounted on top of the frame. The vehicle body has a front receiving hopper separated from a rear storage compartment by means of a partition having an aperture for passage of refuse. A pendular packing device having a refuse engaging face is pivotally mounted within the receiving hopper and arcuately swings to rapidly transfer refuse through the aperture. In order to empty the storage compartment, a rear door is opened to permit egress of refuse and the partition moves longitudinally along the vehicle body to displace refuse out of the storage compartment.Type: GrantFiled: April 30, 2002Date of Patent: February 15, 2005Assignee: Wittke Inc.Inventor: Simon Huang

Patent number: 6817316Abstract: A trailer for transporting live poultry hatchlings has a cargo space for containing a plurality of perforated hatching containers. The hatching containers are stacked to create a central passage for air flow along the length of the trailer from which the air is admitted into a side duct on each side of the trailer through apertures in each side wall of the cargo space. This creates a transverse flow of air through the hatchling containers. A variety of measures may be undertaken alone or in combination to promote a similar transverse flow of air at all positions along the length of the trailer. The size of the apertures, spacing between apertures, cross-sectional area of the side ducts, cross-sectional area of the cargo space, or a combination thereof, may be varied along the length of the trailer to promote a similar transverse flow of air at all positions along the length of the trailer.Type: GrantFiled: December 3, 2003Date of Patent: November 16, 2004Inventor: Lucien Joseph Roussy
