A method of cavitation peening may include coupling a moveable water source to a portable nozzle, through a flexible conduit. The method may include positioning the nozzle adjacent a treatment surface and discharging a first and second stream of fluid through a first and second channel of the nozzle, with the second channel concentrically positioned around the first channel. The first stream may have a first pressure, and the second stream may have a second pressure, the first pressure being greater than the second pressure and the two streams combining to generate a cloud of cavitation bubbles.

A sublimating and abrasive media blasting system including an air compressor, a sublimating blasting unit operably connected to the air compressor and configured to supply a sublimating material, and an abrasive media container operably connected to the air compressor and configured to supply an abrasive media. The blasting system also includes a blasting applicator assembly operably connected to the abrasive media container and to the sublimating blasting unit such that the blasting applicator receives the sublimating material and the abrasive media. The blasting applicator assembly includes an applicator operably connected to the sublimating blasting unit, a first trigger configured to control a flow of the sublimating material and a second trigger configured to control a flow of the abrasive media, an injector, and a nozzle.

A method of producing a measuring tape may include providing a cupped blade with substantially uniform cupping over a longitudinal length of the cupped blade, applying a stress relief operation to a selected portion of only a convex side of the cupped blade to increase curvature of the cupped blade in the selected portion of the cupped blade where the stress relief operation includes bead blasting the selected portion via a dual nozzle shot peening assembly to define a combined bead blast area that is substantially centered with respect to a longitudinal centerline of the blade, and operably coupling the cupped blade to a reel assembly and providing the cupped blade and reel assembly within a housing to define the measuring tape device.

The invention relates to a method comprising the steps of: Abrasion, preferably but non-limited by means of sandblasting which produces mechanical roughing on the surface of the glass substrate, optionally applying a primer on the roughed surface, and applying an ink on this primer by means of screen printing which may be digital inkjet screen printing, drying the injected ink deposited by means of digital screen printing, and performing a tempering process. A glass substrate with an embossed surface finish is achieved which simulates the aesthetic and surface texture of different construction materials, such as stone, wood, granite, marble or porcelain, among others.
