The supporting body is air- and dust-permeable and includes an open-cell foam. A grinding system includes such a holding body and such a flexible grinding device. Full Article
stem Blasting method and apparatus having abrasive recovery system, processing method of thin-film solar cell panel, and thin-film solar cell panel processed by the method By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT Particularly, a thin-film solar cell panel or the like is processed without necessity of attaching and detaching of mask and washing steps with respect to a workpiece in a fine blasting employing a fine abrasive. A negative pressure space (20) and an opposing negative pressure space (40) having openings (22, 42) are opposed by being spaced at a movement allowable interval of the workpiece such as a thin-film solar cell panel or the like and so as to face one side edge in the same direction as a moving direction of the workpiece. Further, a fine abrasive is injected while relatively moving the workpiece in a moving direction (T) with respect to a blast gun (30) in which an injection hole (31) is disposed within the negative pressure space (20), and the fine abrasive injected into the negative pressure space (20) and/or the opposing negative pressure space (40) and a cut and removed cut scrap such as a thin film layer or the like are sucked and recovered through the intermediary of suction devices (21a, 21b) and/or an opposing suction device (41) respectively communicating with the spaces (20) and/or (40).

stem Method and system for screening lubricating oil compositions By www.freepatentsonline.com Published On :: Tue, 28 Apr 2015 08:00:00 EDT A method for screening a lubricating oil composition having at least one base oil of lubricating viscosity and at least one lubricating oil additive is provided, the method comprising the steps of (a) inputting into a computational device an amount of each of the at least one lubricating oil additive, based on the total weight of the lubricating oil composition and, optionally, a value of at least one property associated with each of the at least one base oil of lubricating viscosity; (b) computing a prediction of at least one lubricating oil composition property-determining test result for the lubricating oil composition; (c) computing a cost for the lubricating oil composition; and (d) outputting the results. Also provided are systems and computer program devices for screening lubricating oil compositions. Full Article
stem Strong base amines to minimize corrosion in systems prone to form corrosive salts By www.freepatentsonline.com Published On :: Tue, 05 May 2015 08:00:00 EDT Corrosion by ammonia/amine salts in hydrocarbon streams such as distillation overhead streams that contain a mineral acid and water can be prevented, avoided or minimized by adding certain strong amines to the streams. The amines have a pKa between about 10.5 to about 12 and include, but are not necessarily limited to, dimethylamine, diethylamine, dipropylamine, diisopropyl-amine, di-n-butylamine, diisobutylamine, di-sec-butylamine, di-tert-butylamine, pyrrolidine, piperidine, and combinations thereof. If the hydrocarbon stream further includes a nitrogen-containing compound such as ammonia, a tramp and/or a residual amine which can form a corrosive salt with the mineral acid, then the added amine is a stronger base than the tramp or residual amine, if present. The amount of added amine is greater than total amount of nitrogen-containing compound, so that any corrosive salts formed are less corrosive than the salts that would otherwise form from the ammonia and/or tramp amine.

stem Tool stocker, machine tool system, and tool damage detecting apparatus By www.freepatentsonline.com Published On :: Tue, 18 Mar 2014 08:00:00 EDT A tool stocker includes main stockers for holding a plurality of tools detachably mounted on a main spindle for machining a workpiece, an auxiliary stocker for holding and transferring tools to and from the main stockers, and a tool transfer mechanism for transferring tools between the main stockers and the auxiliary stocker. The auxiliary stocker includes a plurality of tool pods for removably supporting the tools therein, a rail in sliding engagement with outer surfaces of the tool pods, a chain for moving the tool pods in sliding engagement with the rail, and a motor for actuating the chain. The rail has a recess defined therein in alignment with the tool transfer mechanism, such that the tools transferred by the tool transfer mechanism pass through the recess. Full Article
stem Shaping machine system and computer program for controlling a shaping device By www.freepatentsonline.com Published On :: Tue, 03 Jun 2014 08:00:00 EDT A shaping machine system including a shaping device and a computer is provided. The shaping device includes at least one jig mount body configured for mounting a jig; a shaping tool support body configured for supporting a shaping tool; a first drive device configured for rotating the shaping tool; and a second drive device configured for driving the shaping tool support body or the at least one jig mount body or changing a posture of the shaping tool relative to the workpiece. The computer is configured for controlling the first and second drive devices according to predetermined shaping data. The computer includes a jig position measuring unit configured for measuring a position of the jig; a position error detecting unit configured for detecting a position error of the jig, and a shaping data correcting unit configured for correcting the predetermined shaping data according to a jig position error.
