Patent CA-2315108-A1 (CA)
Inventor: GANAN CALVO ALFONSO
IPC: B05B1/02
Filed: 1998-12-16
Abstract: Atomized particles within a desired size range (e.g.., 1 micron to about 5 microns) are produced from two immiscible fluids, a first fluid source containing the formulation to be atomized, and a second fluid source which is contained in a pressure chamber surrounding at least the area where the first liquid is to be provided. The invention provides methods for: the production of templates for microfabrication, such as particles that serve as templates for self-assembly of monolayers; the creation of small particles to serve as building blocks for the microassembly of objects; and the use of an atomizate to etch configurations and/or patterns onto the surface of an object by removing a selected portion of the surface.
Patent CA-2317137-A1 (CA)
Inventor: BLOCK WILLIAM V
IPC: C23C22/84
Filed: 2000-08-31
Abstract: This invention is a method for forming a chemical conversion coating on ferrous metal substrates, the chemical solutions used in the coating and the articles coated thereby. By modifying and combining the features of two existing, but heretofore unrelated, coating technologies, a hybrid conversion coating is formed. Specifically, a molecular iron/oxygen-enriched intermediate coating, such as a dicarboxylate or phosphate, is applied to a ferrous substrate by a first oxidation. The intermediate coating pre-conditions the substrate to form a surface rich in molecular iron and oxygen in a form easily accessible for further reaction. This oxidation procedure is followed by a coloring procedure using a heated (about 120 - 220 F) oxidizing solution containing alkali metal hydroxide, alkali metal nitrate, alkali metal nitrite or mixtures thereof, which reacts with the iron and oxygen enriched intermediate coating to form magnetite (Fe3O4). The result is the formation of a brown or black finish under much more favorable, milder and safer conditions than previously seen with conventional caustic blackening processes, by virtue of the chemical reaction between the intermediate coating and the second oxidation solution. When sealed with an appropriate rust preventative topcoat, the final result is an ultra-thin, attractive and protective finish applied through simple immersion techniques. The finish is a final protective coating on a fabricated metal article and also affords a degree of lubricity to aid assembly, break-in of sliding surfaces or provide anti-galling protection. The finish also provides an adherent base for paint finishes.

Title: Specialized actuators driven by oscillatory transducers
Inventor: WOO EDWARD K
IPC: F15B11/12
Filed: 1999-04-21
Abstract: Actuators (96) for power driven accessories for moving objects, such as vehicle power windows, windshield wipers, vehicle power antennas, power side view mirrors (86), catheter drivers, curtain moving machines, bi-directional rotary motors, thruster mechanisms that move relative to a reaction surface or that drive a driven member relative to itself, use orthogonal oscillatory transducers cooperatively to drive intermediary elements to move these objects bi-directionally along constrained paths. The actuators may also power a pneumatically driven autonomous robot element using dual pneumatic DSES  elements such as planar contact surfaces with an array of apertures which are cyclically switched from a source of compressed air which acts as a lubricant to greatly reduce surface friction to a vacuum source, which acts as a clamping medium increasing contact frictional force. Orthogonal bladders are cyclically pressurized or vented to move a central block relative to a surrounding frame. All cyclic activity is oscillated at the same frequency.  Coordination of phase differences relative to the DSES cycles determines the path of the robotic element which can vector anywhere on a smooth planar surface.

IPC: C12Q1/00
Filed: 1999-07-08
Abstract: Disclosed are methods using neutral red to mediate the interconversion of chemical and electrical energy. Electrically reduced neutral red has been found to promote cell growth and formation of reduced products by reversibly  increasing the ratio of the reduced:oxidized forms of NAD(H) or NADP(H). Electrically reduced neutral red is able to serve as the sole source of reducing power for microbial cell growth. Neutral red is also able to promot e conversion of chemical energy to electrical energy by facilitating the transfer of electrons from microbial reducing power to a fuel cell cathode.< /SDOAB>
