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.

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.

The invention provides a removable retain apparatus for a disc within a disc player. When the disc player of the type is disposed horizontally and the retainer is not needed any more, the user may easily disassembly the removable retainer. The disc player has a tray within which a cavity is provided to accommodate the disc and the cavity defines a circumference along which a plurality of grooves on the tray and each corresponding removable retain apparatus is provided. The removable retain appar...

The invention, consisting of two (2) flat, rectangular, pre-slotted, backing boards with the anterior backing board containing six (6) Velcro.RTM. receiving strips (hooks) affixed in a parallel manner, an equal number above and below the centerline, and the posterior backing board containing between two (2) and six (6) binding straps with one (1) end of the binding strap being permanently affixed to the posterior backing board, with an equal number affixed above and below the centerline, and to ...

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 ...

A reclosable plastic bag (10) having two panels (15) of plastics sheet or film joined to, or integral with, each other, or a combination of both, to define a bag with an opening (13), with separable fastening means (14) of one or more interengagable elongate fib/groove configurations (14a, 14b) are provided to close the opening (13). A slider (100) is positioned in straddling relationship to the fastening means, and includes a support member (111) over-lying the opening to the bag and straddling...

A unique system to insulate and retain the cold temperature of products, liquids, or materials of any type or nature. In the preferred embodiment, the system comprises a series of layers of material as follows: (1) a hard, durable plastic layer of polyvinyl chloride or similar material; (2) a layer of retardant aluminum; (3) a layer of styrofoam; (4) a layer of neoprene; (5) a cavity which is filled with dry ice through an input valve at the top of the system and which is purged through an escap...

A container having a body and a tamper-evident band and a lid for closing the container. The band has a proximal portion frangibly attached to the container body and a distal portion. The distal portion of the band is deformable to an inward extending orientation with the distal portion shaped and positioned to extend inwardly across the peripheral outer portion of a lid. The deformed distal portion of the band optionally has a curvature of 90.degree. to 360.degree. or more. The lid optionally h...

A press that includes a push rod (12) that can be pushed downward to cut and mold miniature components, has a small size and a minimum number of components, and can be easily and precisely controlled. The push rod has a largely upwardly-facing shoulder (140) that lies in a chamber that can receive pressured hydraulic fluid to push down the push rod. A piezoelectric actuator, or piezoactor (18), moves a piston (20) that lies in a pressure cylinder. One end of the pressure cylinder holds hydraulic...
