| 20090049884 | Method for Correcting Metal tube and Corrective Press Die - The forming recesses of a lower die and an upper die are formed to have a semi-oval profile so as to provide a forming space almost oval in section with the dies closed. The parting line between the lower die and the upper die is deviated as much as h from the major axis of the forming space toward the upper die side, and the opening width of the forming recess of the lower die is set to be slightly larger than the opening width of the forming recess of the upper die. A metal bent tube is plastic-deformed into an almost oval shape in section by closing the dies while being compressed in a peripheral direction by the lower and upper dies to eliminate spring-back caused by bending, whereby the buckling and pinching toward the outer side of the tube wall is prevented by the expanded portion of the lower die and buckling toward the inner side of the tube wall is prevented by a step difference formed by the difference in opening width between the lower die and the upper die. | 02-26-2009 |
| 20110146367 | Flared Cone Fitting - The present invention is an improved flared cone fitting of the type having a male portion and a female portion having a tube, an inverted conical annulus, a nut, and a joinder portion. It is improved by the joinder portion including a back-side annular face, which may define a void. The joinder portion may also include an abutment intended to contact a shoulder of a fitting nut and properly direct forces exerted on the nut. | 06-23-2011 |

| 20130305803 | SERVO MOTOR CONTROLLED HYDRAULIC PUMP UNIT FOR TUBE END FORMING EQUIPMENT - Systems and methods for providing tube end forming equipment or machines that utilize the advantage of hydraulic power without having the constant noise, heat, and energy usage associated with traditional hydraulic power units. The end forming machine includes a hydraulic pump that is operated only when a demand from the system for oil pressure/flow is present. This is accomplished by providing a synchronous servo motor and servo drive coupled to a fixed displacement hydraulic pump. The oil pressure of the system is monitored to detect when the pressure drops below a preset value to provide closed-loop control of the servo motor. The servo motor is controlled to rotate the hydraulic pump at the required speed (up to the maximum RPM of the motor/pump combination) as necessary to obtain the desired system pressure during the tube end forming process. | 11-21-2013 |
| 20150027194 | INJECTOR SLEEVE - An injector sleeve adapted to be mounted in a cylinder head of an internal combustion engine, where the injector sleeve comprises a tapered inner surface which constitutes a sealing surface for an injector, where the hardness of the tapered inner surface is higher than the hardness of the outer surface of the injector sleeve. The injector sleeve is produced in a cold forming process. The advantage of the invention is that the injector sleeve is provided with a sealing surface for an injector which is harder than the outer surface of the injector sleeve. In this way, a sealing surface for an injector having small tolerances is obtained without further machining, where the outer surface may be turned to the desired dimensions. | 01-29-2015 |
| 20150135796 | TOOL AND METHOD FOR REPAIRING AN ARC WELDING TORCH - A tool for repairing an interior surface of a conductor tube comprises an elongate body having a proximal end and a distal end. The tool includes a profiled end surface that mates into the interior surface of the conductor tube. The tool includes a central protrusion that extends from the profiled end surface for aligning the tool within the internal passageway of the conductor tube. An imparted force is exerted on the proximal end and the force reshapes the interior surface of the conductor tube around the profiled end surface. | 05-21-2015 |

| 20090038367 | Apparatus for pipe end sizing and method for pipe end sizing - An apparatus for sizing a pipe end comprising: a plug | 02-12-2009 |
| 072370120 | End closing (e.g., crimping) | 4 |
| 20090205393 | Method For Providing an Armature Housing - The invention relates to a method of providing an armature housing having the steps of providing a solid cylinder of malleable material having a first part and a second part; raising at least a part of a perimeter of the first part in a direction away from the second part for defining a raised wall; compressing the second part in an axial direction toward the first part, resulting in a flattened disc generally perpendicular to the first part; and wherein the first part, second part, and at least part of the perimeter are all integrally connected as a single piece. | 08-20-2009 |
| 20090293575 | Closing Method and Closing Machine - A closing machine ( | 12-03-2009 |
| 20090308129 | SHUTTER-TYPE CRIMPER - A crimping device is provided for crimping an outer work piece onto an inner work piece. The crimping device includes at least two jaws forming a throat surface about the outer work piece and movable between a partially closed position wherein the outer work piece is not crimped and a closed position wherein the jaws crimp the outer work piece onto the inner work piece. The jaws are configured as a shutter mechanism so that the throat surface remains substantially continuous about the first work piece as the jaws move from the partially closed position to the closed position. At least one of the jaws moves in straight line motion as the jaws move from the partially closed position to the closed position. At least two of the jaws radially and slide against each other as the jaws move from the partially closed position to the closed position. | 12-17-2009 |
| 20130152658 | Device for and Method of Loading Stents Into Delivery Tubes - A stent loading device is configured to perform a method of loading a stent into a delivery tube that comprises loading a stent into an opening of a crimping device. The stent has an initial uncompressed diameter. The method further comprises crimping the stent via the crimping device in a manner reducing the diameter of the stent from the initial diameter. Still further, the method comprises forcing the stent out of the opening of the crimping device and into a passageway of a delivery tube while oscillating the crimping device. The passageway of the delivery tube has a diameter that is less than the initial diameter of the stent and receives the stent in its compressed state. | 06-20-2013 |

| 20110005292 | METHOD OF FORMING CURLED PORTION - A method of forming a hollow curled portion on a hollow body, the curled portion being oriented from one end to the other end of the hollow body. The method includes a bending step of curving an end of the hollow body toward another end of the hollow body, thereby forming a curled portion, an ironing step of ironing the curled portion with a die, and a recurving step of stopping the die from ironing the curled portion and allowing the curled portion to recurve under its own resiliency in a direction opposite to the direction in which the end of the hollow body has been curved. The ironing step and the recurving step are repeated. | 01-13-2011 |
