연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An automatic dual action apparatus and method for uniformly applying a coating material to the insides of tubular extensions. The apparatus is designed to handle a plurality of pipes of various lengths and inside diameters. The device provides for a unique left to right and, then, right to left application of coating material and a unique interior applicating device that prevents the non-uniform buildup of too much coating material at the beginning of the tubular extensions and not enough at the end of the tubular extensions. The apparatus is capable of being pressurized giving the apparatus the ability to slow the movement of coating material through the tubular extensions as well as to break bubbles of the material that may form on the inside of the tubular extensions being coated and to force the coating material around any pits or weld splatter that may be within the tubular extensions.

Automatic dual action self contained method for uniformly coating the inside of tubular extensions comprising the steps of: A. providing a pair of oppositely positioned rotatable cones with the wide end facing outwardly to receive one end of a tubular extension; B. securedly connecting the narrow end of said rotatable cone, by a connecting means, to a rotating section of uniform circumference within which a radially finned directing means is secured; C. connecting the opposite end of said rotating section, by means of a rotatable pressure sealing means, with a stationary transfer and mixing means from each of two oppositely positioned fluid beds; D. engageably attaching two oppositely positioned belt and pulley systems to the rotating sections of two moveable motors; E. providing two pillow block bearings, one on either side of said belt and pulley systems, for supporting said rotating section whole allowing said rotating section to turn freely; F. providing a connection in the base of said fluid beds whereby gas, such as air, may be introduced into said fluid beds; G. creating a gas receiving chamber in said fluid beds formed by the base and side walls of said fluid bed and a gas permeable separator, which prevents coating material contained in said fluid beds from invading said receiving chamber and which allows gas to pass through said permeable separator into said fluid beds containing said coating material; H. locating an exit port low on a side of said fluid beds so that an exit for said coating material is formed in said fluid bed just above said permeable separator which is in line with and securedly attached to said stationary transfer and mixing means; I. attaching a secure connection to said exit port; J. locating a quick operating valve means just after said exit port connection; K. attaching a tapered nozzle to the opposite end of said quick operating valve; L. secureably attaching a coating material and gas mixing chamber to said tapered nozzle near the base of said tapered nozzle so that said tapered nozzle extends into said mixing chamber and wherein said mixing chamber is connected to said rotatable support cone by means of said rotatable pressure sealing means; M. secureably attaching two oppositely positioned gas introduction means to said gas mixing chamber near the base of said gas mixing chamber where said gas mixing chamber attaches to said tapered nozzle wherein said gas introduction means are positioned so as to cause gas introduction into said gas mixing chamber to rotate and swirl within said mixing chamber and to create a reduced air pressure at said quick operating valve means; N. secureably attaching one end of a gas chamber to said gas mixing chamber between said tapered nozzle and before said rotatable pressure sealing means and secureably attaching the other end of said gas chamber to a quick operating valve means; O. secureably attaching two gas introduction means to said gas chamber, positioned so that one gas introduction means directs gas to said gas mixing chamber and one gas introduction means directs gas to said quick operating valve means thereby enabling gas to be introduced into and withdrawn from said gas mixing chamber; P. providing a measuring means comprised of a geared track along which both said oppositely positioned moveable motors may move and wherein one of said moveable motors is always positioned in a fixed location when receiving said tubular extensions and wherein the second said moveable motor is moved to allow the insertion of the opposite end of said tubular extension into said rotatable cone so that the distance said second moveable motor has traveled on said track from the fixed location of said first said moveable motor can be readily measured; Q. providing an inner directing tube of said radially finned directing means for directing relatively more of said coating means into the center of said tubular extension; R. attaching a plurality of outer directing vanes of said radially finned directing means to the outer surface of said inner directing tube which spiral around the outside of said tube in a direction opposite from the rotation of said rotatable cones and said tubular extensions held by said rotatable cones so that relatively less of said coating material is forced to travel farther around the outside of said inner directing tube thereby slowing said coating material down and throwing said coating material outwardly from said inner directing tube; S. wrapping around and attaching a pair of oppositely positioned vane retention and support rings to said outer directing vanes at each end of said vanes; T. providing a combination of electrically operated quick operating gas valves and a plurality of gas regulation means whereby gas pressure of a predetermined amount will be released when said quick operating valves are electronically opened; U. attaching two oppositely positioned gas manifolds for providing a constant supply of gas to said combination gas regulation means and said quick operating valves; V. connecting said gas manifolds to said gas regulators and connectors said gas regulators to said quick acting valves and connecting said quick acting valves to said connections in the base of said fluid beds, to said oppositely positioned gas introduction means secureably attached to and projected into said gas chamber so that gas of a plurality of pressures and at various times may be introduced to said apparatus; W. providing a programmable controller means which receives information concerning the length of said tubular extensions from said measuring means and which receives inforamtion from an operator concerning the inside diameter of said tubular extensions and which is connected to said gas regulators and said quick acting valves so that the appropriate amount of gas is released and the quick acting valves are opened the appropriate amount of time so that an appropriate amount of coating material is released first from one fluid bed and then the other; X. actuating said programmable controller so that a measured amount of coating material is introduced into said pipe and deposited thereon; Y. attaching a breather-muffler-filter means for filtering and muffling air withdrawn from said dual action apparatus; Z. slidably attaching at their base two oppositely positioned idler means to a downstream track guidance means along which said idlers may move so that said idlers may be positioned beneath said tubular extension and provide support for said tubular extension while rotating; and AA. providing a pair of powered roller means located on said downstream track guidance means so that said tubular extension can be rotated during end preparation.
