Publication number: 20130196574Abstract: The system delivers media blasting material to an interior surface of a large storage tank comprises a substantially upright support structure secured to the surface to be blasted. The upright support structure is preferably vertical. A frame extends across the upright support structure. An extendable arm is affixed to the frame at a section. The section is securely and pivotably attached to the section in such a way to enable the arm to rotate freely inside the large storage tank, so that the blaster secured at the end of the extendable arm can blast the entire interior surface of the large storage tank while the upright support structure remains in place. A robot blaster is positioned at the end of the extendable arm and performs the media blasting. A work station is located nearby the site of the large storage tank and controls the position of the extendable arm relative to the interior surface being blasted via a processor and the operation of the blasting delivery system.Type: ApplicationFiled: June 22, 2012Publication date: August 1, 2013Inventor: Robert J.

Publication number: 20130196575Abstract: A device for removing a coating formed in a slot of a stator core. The device includes a carriage movably attached to a first guide rail assembly to enable movement of the carriage in a longitudinal direction. The device also includes a first drive screw wherein rotation of the first drive screw moves the first guide rail assembly in the longitudinal direction. In addition, the device includes a second guide rail assembly that is attached to the carriage wherein the second guide rail assembly enables movement of the carriage in a direction transverse to the longitudinal direction. Further, the device includes a second drive screw wherein rotation of the second drive screw moves the carriage in the transverse direction. The carriage includes a nozzle that moves within the slot in either or both the longitudinal or transverse directions wherein the nozzle sprays an abrasive media for removal of the coating.Type: ApplicationFiled: January 10, 2013Publication date: August 1, 2013Inventors: Michael R.

Publication number: 20130174607Abstract: A method and system for preparing polysilicon slim rods, the method and system including: placing a piece of polysilicon on a fixture; applying a predetermined laser beam or abrasive jet to the piece of polysilicon; and separating a polysilicon slim rod from the piece of polysilicon. The laser beam may be used for either cutting or for cracking depending on the operating parameters chosen. There may also be various combinations of cutting and cracking used in order to separate the slim rod from the piece of polysilicon. For example, the laser cut may be a scribing and/or partial cut and the separation may be completed by cracking the remaining silicon. In this case, the cracking may be accomplished by, for example, mechanical bending or laser cracking. Generally speaking, a laser beam used for cracking may be different from and have differing operating parameters from a laser beam used for cutting.Type: ApplicationFiled: July 30, 2012Publication date: July 11, 2013Applicant: ATS Automation Tooling Systems Inc.Inventors: Gerald WOOTTON, Steven VAN LOON

Publication number: 20130143473Abstract: The present invention provides an apparatus for removing the unnecessary thin-film layer on the periphery of the substrate of the plate-like member having a square shape, on the surface of which substrate is formed a thin-film layer. The apparatus comprises a chamber to treat the peripheral part where the peripheral part of the plate-like member is inserted and where the unnecessary thin-film layer on the peripheral part of the plate-like member is removed; and a means to move the plate-like member. The chamber to treat the peripheral part comprises a cover to prevent the scattering of the sprayed particles and the dust for treating the peripheral part, the cover having one of its end-sides that forms a ceiling being closed and having the other end-side that is opposed to the ceiling being open and a suctioning cover for treating the peripheral part, having an opening that has the same shape as the opening of the cover to prevent the scattering of the dust.Type: ApplicationFiled: June 6, 2011Publication date: June 6, 2013Inventors: Kazumichi Hibino, Yukinori Suzuki, Kazuyoshi Maeda, Norihito Shibuya
