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.

A vapor plate for covering a manhole of a cargo transport tanker includes a plate member and one or more push rod assemblies. Each push rod assembly includes a guide tube extending through the plate member and a push rod extending through the guide member. A rod of the push rod moves linearly and rotationally within the guide tube. An adjustable collar of a resistance mechanism may be fixed to the rod so that the collar engages a spring allowing a user to generate a resistive clamping force by pushing downward on the push rod. A user may clamp the rim of...

1. A vapor plate for covering a manhole of a cargo transport tanker, the vapor plate comprising: a plate member having a cargo passage opening; andone or more push rod assemblies, each of said one or more push rod assemblies movable between an engaged position and a disengaged position, the push rod assemblies each comprising: a guide tube extending through said plate member and coupled thereto;a push rod journaled for linear and rotational travel within said guide tube;a resistance mechanism coupled to said push rod and having a portion adjustable between a first position and a second position along the push rod, wherein when adjusted to the first position with the push rod assembly in the engaged position, the resistance mechanism provides a first level of resistance and when adjusted to the second position with the push rod assembly in the engaged position, the resistance mechanism provides a second level of resistance that is greater than the first level of resistance; anda seal disposed between said guide tube and said push rod. 2. The vapor plate of claim 1 wherein said plate member further includes a sealing member. 3. The vapor plate of claim 1 wherein said guide tube comprises a tube section, an upper ring plate, and a lower ring plate, wherein one of said upper ring plate and said lower ring plate includes a bushing that carries one or more O-rings, and wherein said seal comprises said one or more O-rings engaging said push rod. 4. The vapor plate of claim 3 wherein said push rod includes a rod, a top handle, and a lower handle, wherein said top and lower handles are fixed with respect to one another. 5. The vapor plate of claim 1 wherein said resistance mechanism comprises a spring. 6. The vapor plate of claim 1 wherein said portion of said resistance mechanism is movable between an unfixed position and a fixed position, and wherein when said portion is unfixed, said mechanism is disabled from being loaded with force to clamp said plate. 7. The vapor plate of claim 6 wherein said mechanism and a length of said rod enable securement of said vapor plate to rims having different heights with a same clamping force. 8. The vapor plate of claim 6 wherein said portion is selectively fixable in a position along a length of said push rod. 9. The vapor plate of claim 1 further comprising a supply pipe coupling connected to said plate, said supply pipe coupling being in fluid communication with said cargo passage opening. 10. The vapor plate of claim 1 further comprising a vapor recovery opening in said plate. 11. A vapor plate for covering a manhole of a cargo transport tanker, the vapor plate comprising: a plate member having a sealing member adhered thereto;a plurality of push rod assemblies, each of said plurality of push rod assemblies comprising:a guide tube extending through said plate member and coupled thereto, said guide tube comprising a tube section, an upper ring plate, and a lower ring plate, wherein one of said upper ring plate and said lower ring plate includes a bushing that houses one or more O-rings;a push rod including a rod having a length, a top handle, a lower handle, said rod journaled for linear and rotational travel within said guide tube, said handles coupled to respective ends of said rod, said handles being fixed with respect to one another;a spring positioned between a collar and said upper ring plate;wherein a position of said collar is adjustable along said length of said push rod and said collar may be selectively fixed and unfixed relative to said push rod, when unfixed said rod is movable through said collar in a linear direction relative to said collar, when fixed said rod is fixed in place relative to said collar in the linear direction when said rod is moved in said linear direction;wherein when said collar is adjusted to a position on said rod to engage said spring and said collar is unfixed, said spring is uncompressed during linear travel of said push rod through said guide tube in said linear direction, and when said collar is fixed, said spring compresses during said liner travel of said push rod through said guide tube in said linear direction; andwherein said O-rings engage said rod of said push rod assembly. 12. A method for attaching a vapor plate to a manhole of a tanker comprising: setting a plate of said vapor plate on a top edge of a rim of a manhole of said tanker;contacting a lower member of a push rod of a push rod assembly with a bottom edge of said rim of said manhole while said push rod extends through said plate and extends through a resistance mechanism;displacing said lower member a distance up and away from said bottom edge and towards said top edge while said push rod extends through said plate and through said resistance mechanism with the resistance mechanism in a disabled position;after said displacement and while said push rod extends through said plate and through said resistance mechanism, enabling said resistance mechanism to be loaded with force to clamp said plate to said top edge, wherein prior to the step of enabling said push rod extends through said plate and through said resistance mechanism and is disabled from being loadable with force to clamp said plate to said top edge;pushing down on a spring of said resistance mechanism to load said mechanism with force to clamp said plate to said top edge; andproviding said force with said resistance mechanism to clamp said plate to said top edge wherein a portion of said resistance mechanism is movable between an unfixed position and a fixed position, and wherein when said portion is unfixed, said mechanism is disabled from being loaded with force to clamp said plate. 13. The method of claim 12 wherein said step of enabling includes fixing the portion of said resistance mechanism to said push rod in a linear position relative to said push rod during displacement of said push rod in the linear direction. 14. The method of claim 13 wherein said setting said plate on said top edge of said rim of a manhole step further comprises rotating a top handle of said push rod so that said top handle extends inward relative to a center of said plate, wherein said top and lower handles are timed thereby resulting in both handles facing inward.
