A pipe puller system and methods of pipe extraction are shown. In one example a pipe to be replaced is pulled by attaching a pulling force to multiple locations along a length of the pipe. In one example pulling forces can be varied between different attachment locations to better control or eliminate tearing of the pipe. In one example, a pipe loosening device may be used prior to pulling the pipe from the ground.

The present invention relates to an assembly for a turbomachine turbine extending along an axis (X), comprising: —an ejection cone (100) comprising a radially outer annular wall (102) defining a flow duct for a flow of hot gases and a sound box radially arranged inside the outer annular wall (102), the sound box comprising a radially inner annular wall (104), —a connecting member (106) intended to be axially inserted between the exhaust housing and the ejection cone (100), the connecting member (106) comprising an upstream annular flange (108) intended to be attached to the exhaust housing and a plurality of downstream securing tabs (110) connected to the inner annular wall (104), —an annular sealing shroud (112) comprising an upstream portion surrounding the securing tabs (110) of the connecting member (106) so as to cover the spaces circumferentially located between the securing tabs (110) and axially located between the upstream annular flange (108) of the connecting member (106) and the radially inner annular wall (104).

A spinning reel includes a reel body, a rotor, a spool shaft, and a drive body. The drive body has a shaft, a first gear disposed on the shaft for rotating the rotor, and a second gear disposed on the shaft for moving the spool shaft. The shaft, the first gear, and the second gear are integrally formed by forging. The first gear includes a first disk part disposed on an outer circumferential surface of the shaft, and a first tooth part protruding axially from the first disk part. The second gear includes a second disk part disposed on the outer circumferential surface of the shaft to be spaced apart from the first disk part, and a second tooth part protruding from the second disk part radially away from an axis of the shaft. The second tooth part has a tip diameter smaller than an inner diameter of the first tooth part.

A reeling device includes: a left spool body; a right spool body; and a yarn transfer mechanism. A first rotation axis of the left spool body and a second rotation axis of the right spool body are parallel to each other, and a position of the left spool body around which the yarn-shaped body is to be wound and a position of the right spool body around which the yarn-shaped body is to be wound are arranged side by side on a first imaginary plane orthogonal to the first rotation axis and the second rotation axis. After a hollow yarn collection is formed in the left spool body, a yarn-shaped body leading portion of the yarn transfer mechanism moves the yarn-shaped body from the left spool body to the right spool body along the first imaginary plane.

The present invention provides a metal strip coil that can suppress a shape failure at an end portion of the coil. A metal strip coil including a metal strip wound around a winding core, wherein the metal strip is wound from one end side toward the other end side of the winding core, turns back at the other end portion, is wound from the other end side toward the one end side of the winding core, turns back at the one end portion, and is repeatedly wound in such a manner, wherein in the turnback, the metal strip has a turnback portion at which the metal strip is wound in a direction perpendicular to the axial direction of the winding core, in a side view of the metal strip coil, the turnback portion is arcuate, and the turnback portions are formed in a multistage manner from the inner circumference toward the outer circumference, and a line connecting a midpoint of the arcuate arc with the center of the arc is formed so as to rotate stepwise in one direction, in an order of the arcuate turnback portions which are formed in a multistage manner from the inner circumference to the outer circumference.
