Systems and methods for cleaning a precipitator including plates and wires associated therewith using dry ice blasting equipment are described. The dry ice blasting equipment primarily includes an elongate wand. The elongate wand is configured to blast dry ice at a high level of pressure to ensure that debris and biproduct that is caked or coated onto the plates and wires is disengaged from the plates and wires. For instance, the dry ice may be blasted at pressures of at least 100 pounds per square inch, and more preferably at least 400 pounds per square inch. To achieve this pressure, the wand may be at least 2 feet in length, and more preferably at least 6 feet in length.

The invention relates to a method for reconditioning a remote control (1) with a housing consisting of an upper shell (2) and a lower shell (3), and a printed circuit board (21) carrying raised keys (5) for triggering control signals by pressure, the raised keys (5) penetrating the upper shell (2), said method comprising: removing (52) the upper shell (2) and the lower shell (3); blasting (55) at least one of the raised keys (5) on the printed circuit board (21) with an antibacterial abrasive; and inserting (58) the printed circuit board (21) with the raised keys (5) supported thereon between a new upper shell (2) and a new lower shell (3).

The present invention is embodied in a carbon dioxide compression and delivery device that uses a plurality of reversible thermoelectric devices and to a method to operate such carbon dioxide compression and delivery device.

A method for separating or recovering materials from electrodes includes: providing a substrate, in particular an electrode substrate, to which a coating has been applied; and at least partially stripping the coating from the substrate by snow blasting.

A method for surface treatment of a workpiece made from a hard-brittle material comprises first blasting employing abrasive grains of higher hardness than a hardness of a base material of the workpiece for forming a three dimensional recess-protrusion profile having protrusions and recesses formed between the protrusions on a surface of the workpiece; and second blasting employing an elastic abrasive having a structure in which abrasive grains carried in and/or on an elastic body made from material with low rebound elasticity for polishing the surface of the workpiece formed with the recess-protrusion profile so as to achieve an arithmetic average roughness Ra of not greater than 1.6 m on the surface of the protrusions and the recesses on the workpiece while maintaining the recess-protrusion profile formed by the first blasting.

This electric current transmission cable includes a non-anodized bare conductor based on aluminum or an aluminum alloy having a hydrophilic external specific surface intended to be in contact with the atmospheric environment, and an inside volume intended to conduct an electric current. The external specific surface of the bare conductor has a first roughness parameter, defined as the arithmetic mean deviation, measurable by profilometry, of peaks and valleys in comparison to a predetermined average profile over a reference length or surface, equal to or greater than 1.9 m. In addition, the inside volume of the bare conductor has oxygen doping of its aluminum-based or aluminum alloy-based components at a ratio equal to or greater than 20%, to a depth of at least 300 nm with respect to the external specific surface.

A method for forming track(s) on low temperature co-fired ceramic (LTCC) substrate, the method comprising the steps of, forming a layer of coating material on an operative face of the LTCC substrate, disposing a stencil on the layer of coating material thereby covering a selected portion of the layer of coating material while leaving exposed a portion of the layer of coating material corresponding to the track(s) to be formed and forming an assembly of the LTCC substrate, the layer of coating material and the stencil, eroding the exposed portion of the layer of coating material by propelling an abrasive material using a blasting gun towards the assembly on the face on which the layer of coating material is formed and the stencil is disposed and separating the stencil from the abraded assembly, wherein the abrasive material has a composition that is compatible with that of the LTCC substrate.
