  • Liner installation in pipes
    Publication number: 20060197262
    Abstract: Apparatus and a method for installing a tubular liner in a pipe, as in repair of underground sewer piping. A feeder is of flexible material, which may be similar to that of which the tubular liner is made, and is connected to an end of the tubular liner. The feeder includes a throat portion through which a quantity of inside-out tubular liner is drawn into the feeder by fluid pressure within the feeder and beyond the throat, and the tubular liner is thence urged by fluid pressure into the pipe where it is to be installed.

  • Tritium removal
    Patent number: 5283010
    Abstract: Where a concrete structure (12) has been contaminated with tritium (whether as gas or as water) the tritium atoms take the place of ordinary hydrogen atoms in water and in hydroxyl groups in the concrete, rendering it radioactive. The degree of contamination may be reduced by irradiating the surface with microwaves to vaporize water, while extracting water vapor from the surface region through a dust filter (28) and a water trap (30). This can considerably reduce the radioactivity, and hence the cost of disposal of the concrete.
