| 20150314357 | PRESS FORMING METHOD - An inner punch ( | 11-05-2015 |
| 20120167655 | METHOD OF FORMING AN INTERNAL TUBE BEADLOCK - A unique tube punch forming die assembly and process is disclosed for forming a bead lock on a malleable fluid conveyance tube which provides for the attachment of a fluid connector to the tube. The fluid connector is held in the tube punch forming die constituting a die assembly where a forming groove is machined in the internal cavity of the fluid connector for forming a bead lock within the inside the fluid connector when the punch forming die is compressed into the tube. The tube is first inserted into the punch forming die, then the die is punched to buckle the tube to form a bead lock in the tube inside the fluid connector as the end of the tube held in a cylindrical support ring. | 07-05-2012 |

| 20110146368 | Method for Making a Tube of a Telescopic Device - Disclosed is a method for making a tube for a telescopic device. The method includes the step of cutting a section from tubular raw material to provide a semi-product of the tube with a desired value of length, the step of pressing the wall of the semi-product of the tube for a first time to make cavities on an external side of the wall of the semi-product of the tube, and the step of pressing the wall of the semi-product of the tube for a second time to deepen the cavities so that the tube is made with a desired depth. | 06-23-2011 |
| 20120216590 | METHOD OF FORMING INDUSTRIAL HOUSINGS - A method of forming a housing which includes roll forming a steel tube radially inwardly with a plurality of rollers each having a rolling axis parallel to the longitudinal axis of the tube, the rollers compressing the tube and forming reduced diameter portions and enlarged diameter portions. The method then includes cutting the tube perpendicular to the longitudinal axis generally midway through an enlarged diameter portion and a reduced diameter portion, forming a plurality of minor image preforms. Finally, the method includes cold working the preforms into the desired shape of the housing and increasing the strength of the steel at least 15% and forming a housing member having enlarged diameter open end and a reduced diameter open end. | 08-30-2012 |

| 20130025342 | MANUFACTURING METHOD OF ROLLER FOR MANUFACTURING PATTERNED RETARDER FILM - A method for producing a roller used for manufacturing a retarder film is provided. The method includes providing a roller having a roller axis and a roller surface; providing an embossing tool having an embossing end; rotating the roller with respect to the roller axis; embossing the roller surface with the embossing tool with a first depth in a first predetermined distance and a second depth in a second predetermined distance; and removing the embossing from the roller surface. The embossing end has a plurality of parallel microgroove structures. The embossing tool embosses the roller surface to generate a first embossing area having a plurality of first embossing patterns and a second embossing area having a plurality of second embossing patterns. | 01-31-2013 |

| 20120125072 | In situ formation of threads throughout bore of sleeve inserted into substrate hole - Threads are formed in situ throughout a bore of a sleeve inserted into a corresponding hole a substrate. A sleeve having a bore is inserted into a corresponding hole of a substrate. A mandrel is rotated through the sleeve. The mandrel has a threaded ended; the threaded end rotating throughout the bore of the sleeve forms threads throughout the bore. Prior to inserting the sleeve into the corresponding hole of the substrate, the sleeve can be placed onto the mandrel. In this case, the mandrel has an increasing diameter at the threaded end thereof, such that the sleeve rests on the mandrel towards the threaded end thereof where the bore has a smaller diameter than the mandrel. The mandrel is then rotated out of the sleeve in a direction opposite the direction in which the sleeve has been inserted into the corresponding hole of the substrate. | 05-24-2012 |

| 20080196472 | Apparatus and method for forming inside surface of tube stock - A method for forming a smooth cylindrical inside wall of a tube is described. The tube is heated and a shaped arbor is inserted into the tube. The tube is forced against the arbor to shape the interior of the tube in general conformity to the arbor and the arbor is removed. The tube may be cut into several sections shaped to be useful as tapered roller bearing cups. | 08-21-2008 |
| 20100147047 | Method of Making an Udersea Pipe, the Method Including Peening Assembly Welds Inside the Pipe - A method of making undersea steel pipes, by assembling unit pipe elements together end-to-end by welding, the steel or metal alloy weld beads of said welds being disposed on the outside of the pipe, wherein localized peening is performed on the inside of the pipe to increase the compression of the steel or metal in the vicinity of the welds and over the adjacent peripheral inside surface of the pipe on either side of the weld so as to create a swath of surface that has been peened over a limited distance L in the axial longitudinal direction of said pipe. The peening is preferably performed using a wheeled carriage fitted with a peening tool. | 06-17-2010 |
| 20100180659 | Method for Marking a Socket - A method is disclosed for marking a socket. The method includes the steps of providing a socket, pressing the socket to make an indented mark, executing thermal treatment on the socket, coloring a portion of the socket near the indented mark to form a printed layer, vibrating and grinding the socket to remove the printed layer from the socket except the indented mark, and electroplating the socket to form a coating on an external side and an internal side of the socket. | 07-22-2010 |
| 20110011149 | METHODS TO PROVIDE A FEATURE ON A NEEDLE - A gripping surface is provided on an outer surface of a needle shield as incorporated into an intravenous catheter assembly. The gripping surface provides a gripping position nearer the catheter adapter, catheter and needle tip for improved balance and control of the catheter assembly during insertion of the catheter. Additionally, the gripping surfaces include a guard feature to prevent a user's unintended contact with various components of the catheter assembly whereby the contact may result in an undesirable “over the bevel” condition. | 01-20-2011 |
| 20110083488 | BIG CRIMPIN CRIMPER - A portable crimping device for crimping around a peripheral edge of at least one sheet metal pipe is disclosed. The device comprises a housing having a top side, a bottom side, a left side plate and a right side plate, a plurality of gear means positioned between the top side and the bottom side, at least one adapter attached to one of the gear means and at least one axis bar attached to another one of the gear means. The peripheral edge to be crimped is inserted into a vertical opening on the bottom side. The one of the gear means spins in a clockwise direction and the other one of the gear means spins in a counterclockwise direction upon rotation of the adapter attached to a power drill. This spinning action of the gear means automatically drives the device onto and around the peripheral edge to form crimps. | 04-14-2011 |
