Title: Pressure welding equipment
Inventor: YOKOSUKA YOSHIFUMI
IPC: G21C21/02
Filed: 1985-03-29
Abstract: PURPOSE:To perform effectively the seal and release of the fuel element inser tion part inserted into a pressure welding equipment and to make the sealing member miniaturized and light-weight and the service life longer by performing the pressure compression in radial direction of a cylindrical high elastic body. CONSTITUTION:A pressure fluid body is led to a pipe path 40 after setting up a fuel element 1 at the prescribed position. The pressure fluid body presses in the radial direction respectively sealing members 32, 33 from the spaces 38, 39 of the inside of groove parts 30, 31. The sealing members 32, 33 are deformed accordingly with being compressed in the radial direction to be pressed and comes into close contact with the outer periphery of the fuel element 1. The space between the outer part of the pressure welding chamber 20 and the space 21 of the inner part can completely be sealed air-tightly. Thereafter the sealing of the gas into the fuel element 1 and the welding of the sealing port are performed by the prescribed method. The sealing member 32, 33 returns to its original shape by its elastic restoring force with the pressure reduction of the grooves 30, 31 after welding. The sealing is thus enabled effectively and the equipment can be miniaturized and lightweighted.

Filed: 1978-06-01
Abstract: A water-cooled engine exhaust manifold has an internal exhaust conduit or heat sheild comprised of a plurality of axially shiftable sections through which the hot exhaust gases pass from the engine to a hot gas turbocharger. A casing encircles the exhaust conduit and is held in spaced relationship to the exhaust conduit so as to provide dead air space or other insulating material space for insulating the hot exhaust gases from the casing. An outer shell encircles the casing and is sealed to exhaust inlet elbows and to fluid inlet flanges to provide a water jacket to cool the surface of the casing. The exhaust inlet elbows communicate with each different section of the exhaust conduit. Clearance is provided between the ends of each section of the exhaust conduit to permit expansion and axial shifting of the sections of the exhaust conduit without, in any way, interfering with the function and operation of the fluid-cooled jacket of the manifold. A novel method for assembling the sections of the exhaust conduit and the other parts of the manifold is provided.

Title: Pipe end beveling device
Inventor: MIYAGAWA NAOTOMI
IPC: B23B5/16
Filed: 1980-05-19
Abstract: PURPOSE: To prevent the vibration of a pipe during the beveling of a large-diameter steel pipe end by beveling a steel pipe end simultaneously by a fixed cutter and a movable cutter attached to the respective tool heads which are disposed facing against each other with respect to the axis of the steel pipe.  
     CONSTITUTION: A spindle head 3 is slightly moved forward to cut the end face of a pipe P with a fixed cutter 12. Then, a motor 13 is inched to turn a screw rod 16 in a direction as shown by an arrow Q thereby slidably moving a sliding key 20 engaged with the screw rod 16 by means of threads in a direction as shown by an arrow R. The movement of the sliding key 20 causes a tool holder 17 to slide and to protrude in a direction as shown by an arrow S so that a cutter 23 fixed to the tool holder 17 cuts into the end of the pipe P. When the chips produced by the cutter 23 become substantially the same with those produced by the fixed cutter 12, the inching motion of the motor 13 is interrupted and the spindle head 3 is advanced so that the cutters 12 and 13 simultaneously cut into the pipe end, thus attaining pipe end cutting process without accompanying the vibration of the pipe.
