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, Kafe, Webinar 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.

A system for catching and containing a spill of a liquid from a rail tank car consisting of a series of catch pans attached end-to-end and placed between the rails of a railroad track is provided. The end walls of each catch pan are shorter than its side walls, with the catch pans located at either end of the series having an end wall extension attached to raise the height of the end wall to that of the side walls. A sealing gasket is placed between adjacent catch pans, and at least one opening extends through the end walls and the sealing gasket between...

1. A catch pan apparatus for catching and containing a spill of a liquid, comprising: a bottom;a first side wall adjoined to and extending upward from the bottom at a perimeter of the catch pan apparatus;a second side wall adjoined to and extending upward from the bottom at the perimeter of the catch pan apparatus, the second side wall opposite of the first side wall;a first end wall adjoined to and extending upward from the bottom at the perimeter of the catch pan apparatus, the first end wall substantially perpendicular to the first side wall and having a height less than that of the first and second side walls;a second end wall adjoined to and extending upward from the bottom at the perimeter of the catch pan apparatus, the second end wall opposite of the first end wall and having a height less than that of the first and second side walls; andan opening in each of the first and second end walls, the opening extending substantially to the bottom and configured to allow the liquid to flow into an adjacently attached catch pan. 2. The catch pan apparatus of claim 1, wherein the first and second side walls extend upward from the bottom of the catch pan apparatus at an angle substantially less than perpendicular and away from the opposite side wall. 3. The catch pan apparatus of claim 1, wherein a distance between the first side wall and the second side wall is substantially equivalent to a distance between a pair of rails of a railroad track. 4. The catch pan apparatus of claim 1, wherein the catch pan is formed from a single sheet of a material, cut and folded to form the bottom, the first side wall, the second side wall, the first end wall, and the second end wall of the catch pan apparatus. 5. A system for catching and containing a spill of a liquid from a rail tank car located upon a railroad track, comprising: a plurality of catch pans placed end-to-end, between and parallel to a pair of rails of the railroad track, each catch pan comprising a bottom, side walls, and end walls, the end walls being shorter than the side walls;a sealing member placed between adjacent catch pans;at least one opening extending through each of the end walls and the sealing member between adjacent catch pans, the opening extending substantially to the bottom of the catch pans and configured to allow the liquid to flow from pan to pan;a drain depending from the bottom of at least one of the plurality of catch pans; andan end wall extension member attached to one of the end walls of one of the plurality of catch pans at an end of the plurality of catch pans, the end wall extension member configured to extend the height of the end wall to the height of the side walls. 6. The system of claim 5, wherein each of the plurality of catch pans is attached to an adjacent catch pan by a plurality of connecting members. 7. The system of claim 5, wherein the drain is connected to a liquid containment means. 8. The system of claim 5, wherein each of the plurality of catch pans is fastened to at least one of a plurality of cross-ties of the railroad track. 9. The system of claim 5, further comprising: a plurality of short side pans placed end-to-end, parallel to and outside of the pair of rails, each short side pan comprising a bottom, side walls, and end walls, the end walls of the plurality of short side pans being shorter than the side walls of the plurality of short side pans;a sealing member placed between adjacent short side pans;an opening extending through each of the end walls of the plurality of short side pans and the sealing member between adjacent short side pans, the opening extending substantially to the bottom of the plurality of short side pans; anda drain depending from the bottom of at least one of the plurality of short side pans. 10. The system of claim 9, further comprising: a plurality of tall side pans placed end-to-end, parallel to and on an opposite side of the pair of rails from the short side pans, each tall side pan comprising a bottom, a first side wall adjoined to the bottom at a position adjacent to one of the pair of rails, a second side wall adjoined to the bottom at a position opposite of the first side wall and having a height greater than that of the first side wall, a first end wall adjoined to the bottom and at a position substantially perpendicular to the first and second side walls, and a second end wall adjoined to the bottom and at a position opposite of the first end wall, the first and second end walls having a height less than that of the first side wall;a sealing member placed between adjacent tall side pans; an opening extending through each of the end walls of the plurality of tall side pans and the sealing member between adjacent tall side pans, the opening extending substantially to the bottom of the plurality of tall side pans; and a drain depending from the bottom of at least one of the plurality of tall side pans. 11. A catch pan apparatus for catching and containing a spill of a liquid, comprising: a bottom;a first side wall adjoined to and extending upward from the bottom;a second side wall adjoined to and extending upward from the bottom, the second side wall opposite of the first side wall;a first end wall adjoined to and extending upward from the bottom, the first end wall substantially perpendicular to the first side wall and having a height less than that of the first side wall;a second end wall adjoined to and extending upward from the bottom, the second end wall opposite of the first end wall and having a height less than that of the first side wall; andan opening in each of the first and second end walls configured to allow the liquid to flow into an adjacently attached catch pan, wherein the opening is substantially triangular with a widest side positioned near a top of the end wall and an opposite vertex positioned substantially at the bottom of the catch pan apparatus. 12. A catch pan apparatus for catching and containing a spill of a liquid, comprising: a bottom;a first side wall adjoined to and extending upward from the bottom;a second side wall adjoined to and extending upward from the bottom, the second side wall opposite of the first side wall;a first end wall adjoined to and extending upward from the bottom, the first end wall substantially perpendicular to the first side wall and having a height less than that of the first side wall;a second end wall adjoined to and extending upward from the bottom, the second end wall opposite of the first end wall and having a height less than that of the first side wall;an opening in each of the first and second end walls configured to allow the liquid to flow into an adjacently attached catch pan;an aperture passing through the bottom; anda tubular member with a bottom end affixed to the bottom and a top end open, the tubular member enclosing the aperture, wherein the bottom of the catch pan apparatus is affixed to one or more cross-ties of a railroad track by passing a fastening member through the aperture enclosed in the tubular member. 13. The catch pan apparatus of claim 12, further comprising a sealing member configured to be attached to the top end of the tubular member and operative to seal the top end of the tubular member after the fastening member is passed through the aperture in the bottom of the catch pan apparatus.
