Patent CA-2219219-A1 (CA)
Inventor: DAVIS KEITH J
IPC: G05B19/4099
Filed: 1996-06-05
Abstract: Ever more stringent environmental restrictions make it ever more challenging to apply coatings by conventional processes like spray painting because of the volatile solvents and hazardous pigments. The present invention is an alternative for applying a coating precisely on a surface. In the method of the invention, we apply appliqués of constant Gaussian curvature to the corresponding areas of comparable curvature. We make the appliqués on a family of molds of different Gaussian curvature and thereby avoid making a "splash" mold of the surface of interest to create the appliqués or encountering the ridges, creases, or gaps that otherwise occur with attempts to cover the surface with flat (planar) appliqués.

Title: Discharge lamp and device for operating it
Inventor: STOCKWALD KLAUS
IPC: H01J65/00
Filed: 1996-05-03
Abstract: According to the invention, a dielectrically obstructed discharge is either superimposed or series-connected in a discharge chamber (3) on or to a conventional, pulsed, dielectrically unobstructed discharge generated between two electrodes (5, 6).      On the one hand the colour location of the lamp (12) can be deliberately altered and on the other ~~~ operating voltages of the discharges can be reduced via the ratio between the electric powers of the two discharges. The degree to which the colour location can be affected may be reinforced by a luminophore coating (4).      To achieve the operation of the invention, the discharge chamber (3) has at leat one additional electrode (13, 14) which is separated from the discharge by a dielectric layer (3).

Title: Methods of making fused particulates by flame fusion
Inventor: CASTLE RICHARD B
IPC: C03C12/00
Filed: 1996-09-20
Abstract: The disclosure describes methods for producing bulk, particulate material that includes solid, generally ellipsoidal particles. Irregularly shaped feed particles with average particle sizes of up to 25 microns on a volume basis are dispersed in at least a portion of a combustible gas mixture by application of force and/or fluidizing agents. The combustible mixture with particles in suspension is then delivered, while controlling agglomeration or re-agglomeration of the particles, to at least one flame front. There, the mixture and suspended particles are uniformly distributed across the surface(s) of and passed through the flame front(s) with a high concentration of particles in the mixture. This flame front and the resultant flame(s) with suspended particles are located in at least one "wall free" zone. In such zone(s) the flame(s) may expand while the particles are maintained in dispersion and heated, with controlled and highly efficient application of heating energy. At least partial fusion occurs within at least the surfaces of the particles at high thermal efficiencies, while agglomeration of particles during fusion is inhibited.

Title: Passenger loading bridge for small aircraft and method of aligning same
Inventor: SMITH BRIAN
IPC: B64F1/305
Filed: 1998-06-09
Abstract: The present invention relates to a passenger loading bridge, in particular an extensible loading bridge having two extensible sections for positioning the loading bridge and for fine alignment with the entry door of an aircraft. The present invention has found that the use of two stages of movement to position the gate of the loading bridge at the aircraft doorway results in efficient and accurate placement, without risk of damage to the aircraft. A first extension movement adapts the length of the bridge to the distance to the plane. This length must closely approximate the distance without risking over-extension which would damage the aircraft, propellers, etc. A second stage of extension then aligns the door without risk to the aircraft or ground personnel. This method is preferably carried out by a loading bridge having two separate telescopic extension assemblies: a first for adapting the length of the bridge, and a second for positioning the aircraft interface section relative to the aircraft door. Advantageously, separate wheeled supports are provided to extend telescopic walkway sections, and to pivot the extended walkway about an arcuate path. Movement separated between separate wheeled supports is more simply and accurately controlled.

Abstract: A chromium-and-ferricyanide-free aqueous cleaner/deoxidizer for aluminum, the cleaner/deoxidizer having an etch rate on titanium that is low enough for practical use in processes where aluminum objects to be deoxidized are held on titanium racks or hangers during the process, combines boric acid, fluoborate anions, and an acid that is stronger than either of boric and fluoboric acids, usually also with an oxidizing agent such as hydrogen peroxide. Rates of etching of aluminum that are at least as much as 50 times the rates of etching of titanium under the same conditions can be achieved, and the deoxidizing of the aluminum is satisfactory for achieving corrosion resistance after subsequent conversion coating of the deoxidized aluminum surface.
