A container with integrally formed non-coring and non-leaking piercing site for use with sterile instruments. A double dome construction is employed to permit needle penetration without coring of the needle and provide sealing between the container and the needle. Provision is also made to insure sealing when a larger diameter plastic needle is employed.

A dually sealable, non-leaking vial for shipping liquid radioactive materials, particularly sterile radioactive materials, and other sterile liquid materials in which the mouth of the vial, as shipped, is sealed by a needle pierceable septum seal and in which a threaded cap is located and held over the septum seal and mouth with the threads thereby held out of engagement with mating threads on the vial by the septum seal. However, upon removal of the septum seal after shipment, the threads of th...

Leaking fuel elements in a fast reactor are identified by measuring the ratio of .sup.134 Xe to .sup.133 Xe in the reactor cover gas following detection of a fuel element leak, this ratio being indicative of the power and burnup of the failed fuel element. This procedure can be used to identify leaking fuel elements in a power breeder reactor while continuing operation of the reactor since the ratio measured is that of the gases stored in the plenum of the failed fuel element. Thus, use of a cle...

The present invention relates to a paper product which can be folded manually to form a non-leaking container, particularly to a paper sheet having proper hardness, one surface being treated with water-proof materials and having a plurality of fold lines roll-pressed thereinto, such that the product can be folded to a very small size for carrying or storage, and can be manually folded about said fold lines to form a non-leaking container.

A dually sealable, non-leaking vial for shipping liquid radioactive materials, particularly sterile radioactive materials, and other sterile liquid materials in which the mouth of the vial, as shipped, is sealed by a needle pierceable septum seal and in which a threaded cap is located and held over the septum seal and mouth with the threads thereby held out of engagement with mating threads on the vial by the septum seal. However, upon removal of the septum seal after shipment, the threads of th...

A storage tank facility for a liquefied gas having an enclosed tank, a vertical dike wall around and spaced from the tank side wall thereby defining a well space between the dike wall and the tank side wall and a plurality of vertical conduits in the dike wall communicating with the bottom of the well space for venting cold liquefied gas vapors therethrough to the atmosphere.

A method for sealing leaking pipes in heat exchangers, comprising the installation, after detection of a leak and determination of the leaking pipe, of extension pieces on the two ends of the pipe, the severing of the pipe adjacent one end and the cutting of openings in the pipe wall adjacent the other end. Subsequently flow conductor tubes are inserted in the two ends of the pipe, and sealing caps are installed on the extension pieces. In operation the pipe is now entirely traversed by the liqu...

Process for disposing of clay, shale or sand containing earth contaminated with petroleum products from leaking underground storage tanks (LUST) as disclosed. The LUST and surrounding contaminated earth is excavated. The clay or shale is separated from the other materials and transported to a site of a cement plant. The non-clay or non-shale material is disposed of in a non-hazardous landfill. The clay or shale is mixed with other cement precursor raw materials and the mixture is ground to form ...

A gas-venting liquid non-leaking expanded polytetrafluoroethylene seal overlapping the periphery of an opening in a sheet substrate forming a container for strong electrolyte solutions.

Disclosed herein is a structure for preventing current from leaking out of devices such as a valve, an intermediate reservoir, etc., which are employed in an electrostatic spray coating apparatus for applying a desired voltage to electrically conductive paint so as to electrostatically spray-coat a workpiece therewith. The current-leakage prevention structure basically comprises any one of the devices each made of an electrically-conductive material, a container made of an insulating material, w...
