Patent CA-2085506-C (CA)
Title: Refractory castable composition and process for its manufacture
Inventor: DELVAUX PIERRE
IPC: C04B35/66
Filed: 1992-12-16
Granted: 2003-07-29
Abstract: A castable refractory composition for use in the production of cast refractory piece, which comprises 1 part by weight of a phosphoric acid solution (H3PO4) having a concentration ranging from 40 to 85% and its primary acidic function partially neutralized by reaction with vermiculite; from 0.1 to 2.5 parts by weight of a mineral such as wollastonite that is refractory and of fibrous structure and may react with one part of the acidic functions of the phosphoric acid that are still free or not neutralized yet; from 0.1 to 2.5 parts by weight of another mineral such as serpentine, Mgo or synthetic olivine, containing at least one cation that may react with another part of the acidic functions of the phosphoric acid that are still free or not saturated yet; and from 0.28 to 1.45 parts by weight of water, being provided that the more concentrated is the phosphoric acid solution, the higher is the amount of water to be present in the composition. When the composition according to the invention is processed in a mixer, it passes from a granular state to a plastic state, and then to a liquid state, without need for any external heating. At that time, the composition may be cast to produce refractory pieces that may be used up to 1000C°. These pieces have very good thermal insulation characteristics, and in particular, a very good behaviour with respect to molten aluminum.

Title: Silica waveguide structure
Inventor: MAXWELL GRAEME DOUGLAS
IPC: G02B6/132
Filed: 1993-02-05
Granted: 2001-11-27
Abstract: A three-dimensional waveguide has path regions which share a common confining region, preferably of uniform refractive index. The path regions are located at two or more levels. The structure is implemented in silica with distributed dopants to distin-guish path regions from the confining region. The structure is made using flame hydrolysis to deposit layers. Melting point de-pressants are incorporated so that later deposited layers can be melted without melting the whole structure. Some layers of pure silica can be deposited by chemical vapour deposition. These layers are never melted and they provide a stabilising skeleton when complicated structures are melted.

Title: Decorative, non-combustible synthetic fire-log
Inventor: DELVAUX PIERRE
IPC: C04B16/08
Filed: 1995-03-21
Granted: 2001-02-27
Abstract: Disclosed is a decorative, non-combustible, synthetic fire-log for use in a gas or oil burning fireplace or stove. This synthetic fire-log has a density ranging from 15 to 45 lb/ft3. It is made by pouring a mineral foam into a mold shaped as a natural wood-log and letting this foam harden in the mold to form the synthetic fire-log prior to unmolding the same and letting it dry. The foam that is used for such a molding comprises 1 part by weight of a solution of phosphoric acid in which polyvinyl alcohol is dissolved in such an amount as to make the solution viscous; from 0.03 to 6 parts by weight of wollastonite containing from 0.5 to 4% by weight of a carbonate salt; from 0.2 to 10 parts by weight of water optionally one or more pigments to give a natural wood-like aspect to the synthetic fire-log; and, optionally also, a small amount of reinforcing glass fibers. The synthetic fire-log that is so-obtained looks like a natural wood-log and has the same glowing aspect in use. Moreover, it does not generate soot and advantageously ensures a full combustion of the gas or oil mixture fed into the fireplace or stove, thereby resulting in a substantial reduction in the amount of carbon monoxide released in the atmosphere.

Title: Compressive strength testing of hpc cylinders utilizing confined caps
Inventor: JOHNSON CLAUDE
IPC: G01N3/02
Filed: 1995-06-01
Granted: 2001-07-24
Abstract: A confined capping system provides a simple approach for compressive strength testing of high performance concrete specimens. The test specimen ends are capped with a conventional capping compound confined in steel rings larger in diameter than the specimen. The capped rings are compression tested in a conventional way. This method thus employs standard concrete laboratory testing equipment. An inexpensive customized capping apparatus may be used for preparing the specimen ends. The method ensures that confinement is provided to the cap without having to place tight controls on specimen end roughness prior to capping and on the cap thickness itself.

Abstract: A refractory slab (2) for use in an electrolytic cell has a top surface, a bottom surface and at least one engagement surface (2D) for engagement with a corresponding surface (ID) of an adjacent slab (1). The engagement surface (2D) has a top region and a bottom region that extends perpendicularly from respective top and bottom surfaces. The top and bottom regions are connected by a sloping region such that the angle between the sloping region and the top and bottom regions is greater than 90°. The slabs eliminate straight lines at joints along which bath from the electrolytic cell may infiltrate during use. The engaging surfaces may also be arranged such that the slabs can be placed into position when forming a refractory lining by vertical movement alone, which can lead to shorter times for relining of the cell.
