摘要： The present method for machining a part includes wire electro-discharge machining the part to create a recast layer, and then removing a zinc content of the recast layer without substantially altering the remainder of the initial composition make-up of the recast layer. The final composition make-up of the recast layer is substantially identical to the initial composition make-up except for the removed zinc content.

摘要： The present disclosure provides a system for aiding in the removal of one or more test specimens from a build plate. The system includes an anchor portion disposed separate from the build plate. The anchor portion may include one or more attachment points for receiving and attaching one more stretchable bands. The stretchable bands may be sized to be stretched from each of the one or more specimens to the one or more of the attachment points. In this manner, a pulling force may be imparted on each test specimen, and the test specimen is moved away from the build plate during its removal. The system may be utilized particularly in conjunction with EDM and removing the test specimens using an EDM wire.

摘要： This invention concerns an intravascular blood pump for percutaneous insertion into a patient's blood vessel. The blood pump comprises a pump casing having a blood flow inlet and a blood flow outlet, an impeller arranged in said pump casing so as to be rotatable about an axis of rotation. The impeller has blades sized and shaped for conveying blood from the blood flow inlet to the blood flow outlet. The blood pump comprises a drive unit for rotating the impeller, the drive unit comprising a magnetic core including a plurality of posts arranged about the axis of rotation and a back plate connecting the posts and extending between the posts in an intermediate area. A coil winding is disposed around each of the posts. The coil windings are controllable so as to create a rotating magnetic field, wherein the impeller comprises a magnetic structure arranged to interact with the rotating magnetic field so as to cause rotation of the impeller. A material of at least a portion of at least one of the posts is integral with a material of the intermediate area of the back plate. Further, the invention concerns a method of manufacturing a magnetic core and a method of manufacturing an intravascular blood pump.

摘要： A machine tool includes a ram extending in a longitudinal direction and being disposed horizontally, a processing head attached to the ram, a tower connected to the ram in a state of upwardly standing at an intermediate position in the longitudinal direction of the ram and having an adjustable height, a front arm connected to a front portion of the ram, and a rear arm connected to a rear portion of the ram. The tower includes a base portion fixed to the ram, an arm connection portion connecting the front arm and the rear arm, and a jack-up bolt. The jack-up bolt is in contact with one of the base portion and the arm connection portion in a vertical direction, and threadingly engaged to the other one of the base portion and the arm connection portion. The jack-up bolt pushes the arm connection portion upwardly by screwing or unscrewing.

摘要： Combustion burner panels, submerged combustion melters including one or more of the panels, and methods of making the same are disclosed. In certain embodiments, the burner panel includes a panel body having first and second major surfaces, at least one oxidant through-passage extending from the first to the second major surface, and at least one fuel through-passage extending from the first to the second major surface. Oxidant and fuel delivery conduits are positioned in the respective passages. The oxidant and fuel delivery conduits include proximal and distal ends, at least some of the distal ends positioned away from the first major surface of the panel body. In other embodiments the burner panels include a frame enclosing a porous material having through passages for fuel and oxidant. The burner panels may enable delaying combustion in a submerged combustion melter, and therefore promote burner life and melter campaign length.

摘要： A member (10), for bearing a load, including a load receiving portion (12) at which the load is applicable to the member. A strainable portion (14) is connected to the load receiving portion to be strained by the load. A datum (16a) is defined and an elongate portion (18) defines another datum (18a). The datums are arranged such that relative displacement therebetween indicates an amount by which the strainable portion is strained. The strainable portion defines the datum.

摘要： The present invention relates to a method and system for treatment of a surface of a metallic material component, the method comprising the steps: electro-spark treating the surface of the metallic component by means of an electro-spark electrode, wherein the metallic material is a basically ferritic, perlitic and/or austenitic steel and the method creates a thin layer with martensitic microstructures at the surface of the metallic material component. Serpentines and quartz can be incorporated by an additional step as well as the surface randomly structured by this.
