131 BUSHING FOR THE CONNECTION OF TWO TUBULAR ELEMENTS AND METHOD FOR THE PRODUCTION THEREOF PCT/IB2015052341 2015-03-30 WO2015151016A3 2015-11-26 VIZZARRI DOMENICO
A bushing for the connection of two tubular elements (2, 3) has an outer coupling (5) and an inner sleeve (6), which is axially locked inside the outer coupling (5), is provided with a plurality of annular teeth (14) projecting towards the inside of the bushing relative to a lateral wall (13) of the inner sleeve (6), and also has a plurality of annular recesses (16), which are obtained at an outer surface (17) of the lateral wall (13).
132 Circular and oval flanged rings for connecting ducting and method of making US616655 1996-03-15 US5983496A 1999-11-16 Jeffrey Allen Hermanson
A method of making Circular and Oval Flanged Rings, for the connection of thin walled circular and oval ducting, including Circular and Oval Flanged Rings having a Sheet Metal and Air Conditioning Contractors National Association (SMACNA) standard T24 Profile. Thin gauge Lock Form Quality steel, from 10 to 20 gauge, is cut into strips with the strip ends butt welded forming Flanged Ring Band Stock which is inserted and clamped into a Spinning Die. The Spinning Die is rotated by a horizontally configured lathe output shaft presenting the extended portion of the Flanged Ring Band Stock for machine tool forming. Standard machine tools are used to form the Flanged Ring Band Stock into a Circular Flanged Ring including the SMACNA T24 Flanged Ring Profile. A Circular Flanged Ring is cut along a diameter into Semi-circular Flanged Ring Portions; straight segments including segments with SMACNA T24 Linear Segments are roll formed, assembled into a oval shape within a fixture and welded forming the Oval Flanged Ring. The method of making and the Circular and Oval Flanged Rings are disclosed.
133 Sheet metal bending tool US113331 1993-08-30 US5394729A 1995-03-07 Gary W. Eisenhower, Jr.
A sheet metal bending tool for prying and bending sheet metal flanges such as those found on vehicle doors, air conditioning duct work, and the like. The tool includes a handle having a pair of flange engaging jaws at opposed ends thereof in which a first jaw is positioned at a right angle to the handle and a second jaw is positioned colinearly with the handle. Alternate embodiments of the present invention include a third jaw positioned adjacent to the first jaw and an angle adjustment assembly for facilitating an adjustment of the relative angle between one of the jaws and the handle.
134 Tube end double end forming method and apparatus US221377 1988-07-19 US4910991A 1990-03-27 Reed Bertolette; Nicholas J. Marracino
A continuous supply of tubing is fed intermittently into a work station. Partial cuts are made at periodic intervals by a cutoff head that operates in timed relation with tube clamping device. Tube gripping device then pulls on the end portion or segment to position it precisely downstream of and in alignment with the freshly cut tubing end. A double tube end forming device moves in between the downstream end of the tubing and the upstream end of the tube segment. This device has tube end forming heads that include tooling for suitably shaping both these ends simultaneously.
135 Bending apparatus US39160 1979-05-15 US4284022A 1981-08-18 Yukio Kanazawa
An apparatus used for forming lips by outwardly bending the end of a metal plate which may be joined with the bent end of another plate so as to form a duct used for an air-conditioning ventilation system. The end to be bent is reinforced with a continuous guide member connected thereto, said guide member being generally L-shaped in cross-section, leaving a given width to form a lip. The bending apparatus is comprised of a roller for engaging and rotating along the guide plate which serves as a supporting member and a guide rail. The apparatus is further comprised of a pressing disc for contacting under pressure the end to be bent. The disc acts in cooperation with the engaging roller at a position opposite thereto. Accordingly, the end is bent as the disc and roller are rotated. The bending apparatus is designed to move along said reinforced guide, bending the end of a metal plate so as to continuously form a lip which is L-shaped in cross-section. The space between the pressing roller and the engaging roller can be adjusted relative to the thickness of a metal plate to be bent by an adjustment means. Said adjustment means positions the whole apparatus in place on a metal sheet. In addition, the pressing disc includes a shaping roller which contacts a portion of the end to be bent, said shaping roller making the bending portion easier to carry out. A power source is placed on the bending apparatus, the power source being counterbalanced in order to eliminate any biasing force on the shaping portions of said engaging roller and said pressing disc during operation.
136 Roller bender for offset printing plates US3733872D 1971-07-15 US3733872A 1973-05-22 GREGOIRE C
A bending machine for offset printing plates. The bender includes a table support for the plate to be bent. The table is provided with end edges having contours identical to the desired contours of the end edges of the plate after bending. Spring biased rollers are employed to bend the end edges of the plate around the contoured ends of the table support.
