Publication number: 20190084031Abstract: An apparatus and methods of forming a metallic closure for a metallic bottle are provided. The present disclosure provides a pre-formed metallic closure and apparatus and methods of forming the metallic closure. The metallic closure can be reformed with a peripheral channel before the metallic closure is positioned on a metallic bottle. An inner tool and an outer tool can form the channel in one operation. Optionally, a thread can be formed on a metallic closure prior to use of the metallic closure to seal a metallic bottle. A capping apparatus of the present disclosure uses less force to seal a metallic bottle with a metallic closure of the present disclosure compared to the force required with a prior art ROPP closure. Accordingly, a metallic closure of the present disclosure can seal a metallic bottle formed of less material (such as by being thinner) than prior art metallic bottles.Type: ApplicationFiled: September 14, 2018Publication date: March 21, 2019Applicant: BALL CORPORATIONInventors: John R.

Publication number: 20190084038Abstract: In the casting device according to the present invention, when a mold varied in outer size depending on a position passes through a heat shielding portion between a heating chamber and a cooling chamber, a flexible portion of a heat shielding body is bent to fit an outer size of the mold. Accordingly, it is possible to minimize a gap between a wall surface of the mold and the heat shielding body and to effectively perform heat shield between the heating chamber and the cooling chamber. This prevents deterioration of cooling performance inside the cooling chamber to improve temperature gradient of a casting. As a result, it is possible to improve strength of a produced casting. Further, it is possible to reduce an amount of energy wastefully emitted to the cooling chamber, of energy emitted from a heater. This makes it possible to improve energy efficiency.Type: ApplicationFiled: March 9, 2017Publication date: March 21, 2019Inventors: Takeshi KANEKO, Masaki TANEIKE, Hidetaka OGUMA

Publication number: 20190084068Abstract: In thin sheet welding, when a heat input amount relative to a sheet thickness is too large, a welding defect such as a deviation from aim due to occurrence of a strain or burn through may easily occur. When a welding current is decreased to reduce the heat input amount, there is an issue in which an arc tends to become unstable. In arc welding in which short-circuit and arcing are repeated, first heat input period (Th) and second heat input period (Tc) having a heat input amount less than that of first heat input period (Th) are periodically repeated and a welding current during an arc period in second heat input period (Tc) is decreased to extinguish the arc. This reduces the heat input amount into a welding object and suppresses burn through or a strain upon welding, while making the arc stable.Type: ApplicationFiled: March 17, 2017Publication date: March 21, 2019Inventors: YUYA FURUYAMA, ATSUHIRO KAWAMOTO, JUNJI FUJIWARA, MASARU KOWA, KAITO MATSUI

Publication number: 20190084072Abstract: Welding system and method permit exchange of data with Smart Grid monitors and/or controllers. The welding systems include a welding power supply configured to convert power between the power grid and the welding power supply. A grid interface cooperates with control circuitry to transmit data to and/or from the grid monitors and/or controllers on the grid side. The control circuitry may control operation of the welding power supply based upon data from the grid. The system may include power generation devices (e.g., engine-drive generators) and energy storage devices (e.g., batteries). The control circuitry may control operation of such devices, the exchange of power between them, and the draw of power from the grid or the application of power to the grid based upon the data exchanged with the grid monitors and/or controllers.Type: ApplicationFiled: October 17, 2018Publication date: March 21, 2019Inventors: Thomas A.

Publication number: 20190084075Abstract: A method for forming a component includes providing a first layer of a mixture of first and second powders. The method includes determining the frequency of an alternating magnetic field to induce eddy currents sufficient to bulk heat only one of the first and second powders. The alternating magnetic field is applied at the determined frequency to a portion of the first layer of the mixture using a flux concentrator. Exposure to the magnetic field changes the phase of at least a portion of the first powder to liquid. The liquid portion couples to at least some of the second powder and subsequently solidifies to provide a composite component.Type: ApplicationFiled: November 28, 2018Publication date: March 21, 2019Applicant: Grid Logic IncorporatedInventor: Matthew J.

Publication number: 20190084076Abstract: A method for producing a hot-rolled clad composite material may involve cleaning surfaces of multiple flat products, at least one surface of which has a natural unevenness. The cleaned surfaces may then be connected and brought into contact by stacking the flat products. The flat products may then by regionally welded to create a flat product package. The method may further involve heating the flat product package to an initial hot-rolling temperature, hot-rolling the flat product package to form a hot strip, and either cutting the hot strip into plates or sheets or coiling the hot strip to form a coil.Type: ApplicationFiled: March 2, 2017Publication date: March 21, 2019Applicants: THYSSENKRUPP STEEL EUROPE AG, thyssenkrupp AGInventors: Hans FERKEL, Stefan MYSLOWICKI
