Patent number: 12134125Abstract: Methods for manufacturing rotary target materials that allow a material to be cast in a melting zone of a casting vessel while the vessel is rotated such that a melting zone is below a casting zone. The vessel is sealed and the pressure inside the vessel is reduced and the exterior of the vessel is heated. The melting zone of the vessel is heated to a temperature that melts the material and releases any trapped gasses which can be pumped out using the vacuum pump. Once the melting zone and molten material have reached a specified temperature, outgassed, and the casting zone has reached a temperature to maximize adhesion and reduce voids and defects, the vessel is rotated until the melting zone is directly above the casting zone to transfer the material from the melting zone to the casting zone.Type: GrantFiled: February 12, 2021Date of Patent: November 5, 2024Assignee: Junora LTDInventors: Dean Plaisted, Nancy Norberg, Paul Carter, Larry Ferrin, Patrick Morse

The displacement element can be pressed into the component to be produced for dense feeding. In a method for producing a cylinder head by casting, wherein the steel upper core is used as a substitution for a sand cover core, for dense feeding the displacing element is pressed into the melt that forms the cylinder head in the solidified state.Type: GrantFiled: October 22, 2015Date of Patent: April 14, 2020Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Andreas Fent, Richard Schaechtl, Hubert Lang, Marcus Stier, Thomas Summer

Patent number: 10556268Abstract: An apparatus for manufacturing items of light alloy or similar comprises a mould (10) that includes two half-moulds (12, 14), lower and upper, able to be coupled together. The lower half-mould (12) defines a moulding cavity (20) adjacent to a supply duct (16) of liquid metal that passes through it up to an introduction passage (18) of the liquid metal in the moulding cavity (20). The upper half-mould (14) is associated with at least one moveable punch (24) provided with a moulding surface (21) that defines the shape of an item to be moulded together with the moulding cavity (20). Each punch (24) performs the function of a shutter to stop the flow of liquid metal towards the moulding cavity (20). The apparatus includes temperature control means and temperature sensors connected with a control unit (32) that prevents the movement of the moveable punches (24) if the temperature of both half-moulds (12, 14) is not comprised within a predetermined range of values.Type: GrantFiled: May 19, 2016Date of Patent: February 11, 2020Assignee: Alustrategy S.R.L.Inventor: Marco Soliani

Patent number: 10493521Abstract: A die casting machine includes a clamping device which opens and closes and clamps a pair of die halves, an injection apparatus which performs injection to the pair of die halves by making a plunger move forward in a sleeve communicated with a space between the pair of die halves, and a control device which controls the clamping device and injection apparatus. The control device includes an injection control part and press-use clamping control part. The injection control part controls the injection apparatus so as to start the injection in a state where the pair of die halves face each other through a gap. The press-use clamping control part controls the clamping device so that the die contact and clamping are carried out after the start of injection. Further, the injection control part performs control for decelerating the plunger before the plunger stops.Type: GrantFiled: May 1, 2017Date of Patent: December 3, 2019Assignee: Toshiba Kikai Kabushiki KaishaInventors: Kouei Nakata, Satoru Aida, Toshiaki Toyoshima

Patent number: 10428627Abstract: A closed loop pneumatic pumping system is provided. The system uses a gas compressor and a high pressure gas tank to exert pneumatic pressure against a reciprocating piston over a wellbore. The piston is connected to a rod string and downhole pump for pumping formation fluids from a wellbore. The system includes an electronic controller that controls movement, including pump speed of the piston as it cycles between upstrokes and downstrokes within a cylinder over the wellbore. In one aspect, speed is controlled by adjusting a speed of the compressor. In another aspect, speed is controlled by adjusting the position of an upstroke control valve and a downstroke control valve. In one aspect, the pump stroke controller is configured to adjust a speed of the upstroke and a speed of the downstroke in response to signals indicative of pump fillage. A method for optimizing pneumatic pumping speed at a wellbore is also provided herein.Type: GrantFiled: September 7, 2016Date of Patent: October 1, 2019Assignee: Encline Artificial Lift Technologies LLCInventor: William G. Elmer

Patent number: 10384262Abstract: A die casting method and apparatus are provided, thereby making it possible to produce a thin diecast product that has hitherto been considered impossible to realize, and a diecast product is also provided. A semi-solidified metallic material is formed having particles in solid phase of a particle size less than 30 ?m, and is thereupon injected into a die. A die casting machine has a sleeve into which a melt of metallic material is poured, and the semi-solidifying material there when it has a certain proportion of solid phase reached is injected into the die with a plunger to which pressure is applied. The melt of metallic material is poured into the sleeve so that the material occupies inside the sleeve at a proportion in vertical cross-sectional area of 30% or less. The particle size in this semi-solid material is held unvaried in a product as diecast.Type: GrantFiled: April 13, 2015Date of Patent: August 20, 2019Assignee: TOHOKU UNIVERSITYInventors: Masayuki Itamura, Kouichi Anzai

Patent number: 10300528Abstract: Disclosed is an apparatus for loading one or more alloy ingots into a molding machine. The apparatus includes a holder configured to hold a plurality of the alloy ingots and dispense one or more of the alloy ingots into a melt zone of the molding machine through an opening in a mold of the machine. The holder is moved in a perpendicular direction with respect to an axis along a center of the opening in the mold between a first position in line with the opening in the mold to dispense one or more of the alloy ingots and a second position away from the opening in the mold. The apparatus can carry ingots of amorphous alloy material so that when the machine melts and molds the material, it forms a bulk amorphous alloy containing part.Type: GrantFiled: March 7, 2017Date of Patent: May 28, 2019Assignee: CRUCIBLE INTELLECTUAL PROPERTY, LLCInventor: Joseph W.
