A retaining device to hold a butterfly valve stem (26) in the valve body upon a shearing or breaking of the stem. The retaining device is mounted within a bore (38) in the valve body (12) beneath the stem packing and includes pins (44) extending from the stem (26) which engage in abutting relation a support ring (64) mounted in a groove (56) in the bore to restrain any outward movement of the stem.

Tritium formed in the treatment of spent nuclear fuel and during storage of liquid, radioactive waste products is retained by adding oxygen to said liquid, radioactive waste products, reducing in a subsequent stage the oxygen enriched with tritium and separating it from the tritium. The reduction can be carried out with NO. The higher nitrogen oxides formed can be reacted to nitric acid.

There is provided a method for retaining the shape of gloves e.g. leather golf gloves with one or more curved fingers by placing a glove on an electrically heated form having a shape corresponding to the curved gloves, with a sheet of paper between said form and the interior of the glove, for a sufficient time to retain the shape of the glove, especially the curvature of the fingers thereof.

A device that allows a user to retain carbonation in conventional plastic beverage bottles for extended periods of time. In a first embodiment, a fluid impermeable, inflatable, elastic bladder is employed to fill the vapor space in the bottle when the beverage is dispensed. With the vapor space filled, the CO.sub.2 carbonization gases cannot dissipate. The bladder is removably attached to a nozzle cap. The nozzle cap incorporates an arrangement including an inflating tube that permits a user to ...
