An orthopedic device, such as an intramedullary nail for internal fixation of a bone and a method of manufacturing the same. The orthopedic device may be formed from a medical grade powder via an additive manufacturing process. The forming process may include heat treating the additive manufactured component and machining the heat treated additive manufactured component to form the orthopedic device. Further, the orthopedic device may be formed to include an internal sensor probe channel that extends within at least a portion of the wall of the device, but which does not protrude through an outer portion of the wall. Embodiments further include a dynamizing intramedullary nail that accommodate adjustments in the relative axial positions of one or more sections of the orthopedic device. The devise may include features in an inner region of the orthopedic device that may alter an elastic modulus of the orthopedic device.

The device further includes a dry ice recycling device, the dry ice recycling device includes a dry ice recycling collector and a condenser pipe, and two ends of the condenser pipe are communicated with the box and the dry ice recycling collector respectively.

An abrasive blasting system has an abrasive container or pot, preferably with a downwardly conically shaped interior bottom surface. A slurry delivery tube is positioned within the pot, with an open bottom end positioned at an operative distance above the bottom of the pot. The slurry delivery tube runs vertically upward and exits the pot, ultimately running to a hose and nozzle. With an abrasive slurry of solid particulate abrasive media and water inside the pot, air pressure is applied within the pot. When a relatively lower pressure is created in the slurry delivery tube, the resulting pressure differential moves the slurry downward within the pot, then upward through the slurry delivery tube, through the hose and ultimately to the nozzle, where it is directed by an operator onto a workpiece. The system is especially useful when using very fine abrasive material.

A cut-to-length line for processing coiled sheet metal having a thickness of greater than 0.200 inches has an uncoiler, a descaler, and flattening machinery which may be a stretcher leveler or a temper mill. The line is operated in an advancement mode by (i) the advancing the sheet metal through the line; and (ii) descaling the sheet metal in the descaler. In one aspect, when a length of sheet metal to be stretch leveled is positioned in the stretcher leveler, the line may be operated in an idle mode by: (i) stopping the advancement of the sheet metal from the uncoiler through the descaler; (ii) stopping descaling of the sheet metal in the descaler; and (iii) stretch leveling the length of the sheet metal. When stretch leveling is complete, the line may be operated in the advancement mode.

The present disclosure provides methods forming a stainless steel part. A method for forming a stainless steel part may comprise providing a substrate comprising stainless steel and at least one depression that projects into at least a portion of the substrate. The at least one depression may be in accordance with a depression pattern. A coating material may be provided on at least a portion of the surface having at least one depression.

The present invention is a nozzle assembly having a nozzle main body including an ejection material suction port and an ejection port which ejects the ejection material with the compressed air, and an air nozzle which jets the compressed air into the nozzle main body. The nozzle main body includes a mixing chamber which mixes the ejection material with the compressed air, a first pathway directed from the ejection material suction port toward the mixing chamber, and a second pathway directed from the mixing chamber toward the ejection port. The air nozzle includes a compressed air jet portion and a third pathway directed to the compressed air jet portion, and the third pathway is inserted into the nozzle main body. The compressed air jet portion of the air nozzle is provided with a flow contracting portion having an opening.

A method of manufacturing a wood-type golf club head, the golf club head including a face member that forms a face portion and a main body member to which the face member is to be joined, the method including a step of forming, in the face portion of the face member, a plurality of grooves and a concave portion extending so as to surround the plurality of grooves, a step of joining by welding the main body member and the face member in which the plurality of grooves and the concave portion are formed, and a step of grinding a region from the concave portion to an end portion of the main body member, the region including a welded portion between the face member and the main body member.

A method of manufacturing a wood-type golf club head, the golf club head including a face member that forms a face portion and a main body member to which the face member is to be joined, the method including a step of forming a plurality of grooves in the face portion of the face member; a step of joining by welding the main body member and the face member in which the plurality of grooves are formed; and a step of blasting an elastic abrasive onto the face portion.

This invention relates to compositions and methods for the at least partial dissolution, disruption and/or removal of deposit, such as scale and other deposit, from heat exchanger components. The heat exchanger components can include pressurized water reactor steam generators. In accordance with the invention, elemental metal is added locally to the surface of the deposit and/or anodic or cathodic current is applied locally to the deposit surface to destabilize or weaken the deposit. Subsequently, mechanical stress is applied to the weakened deposit to disrupt and remove the deposit from the surface of the heat exchanger component.
