Abstract: Electrolytic interior surface treatment apparatus (100) for the electrolytic treatment of an internal surface (102) of a metallic pipe (1) includes at least two oppositely polarised electrodes (3, 4). The apparatus (100) includes: an electrically insulating centralisation arrangement (106) to keep, in use, the electrodes (3, 4) centred within the pipe (1); and an electrically insulating flexible connection arrangement (104) located between the two electrodes (3, 4) to permit movement of one electrode relative to the other. The centralisation arrangement (106) includes a plurality of spaced apart centralisation devices (5, 6). Each centralisation device (5, 6) includes an electrically insulating mounting (7) for mounting the respective centralisation device (5, 6) to the apparatus (100). Each centralisation device (5, 6) includes a plurality of flexible elements (108), each of which is fixed to the mounting (7) and extends outwardly from the mounting (7).

Abstract: The invention provides electrochemical surface treatment apparatus (100) for the treatment of radioactively contaminated internal surfaces of a pipe (1). The apparatus (100) includes an electrode device (102). The device (102) includes an electrode (4), which, in use, is located in electrolyte liquid (2) within the pipe (1) adjacent a treatment surface (104) to be treated with a gap (106) defined between the electrode (4) and the treatment surface (104). The apparatus (100) includes a circulation arrangement (108). The electrode (4) defines an internal passage (110). In use, the circulation arrangement (108) causes a recirculating flow of electrolyte liquid (2) through the gap (106) in one direction and along the passage (110) in an opposite direction.

Abstract: A central fuel management system includes a pre-authorization module arranged to receive carrier, trailer, and driver identifying information; match, for each meter under a truck rack, one or more loads associated with the carrier, trailer, and driver identifying information; query for each of the one or more loads: a nomination system containing information on book stock; a terminal automated system containing information on physical inventory at two or more terminals; and a third party allocation management system containing information on loading quantity limits. On the basis of the query the pre-authorization module decides whether each load of the one or more loads is authorized prior to its loading. Where authorized, the driver loads at the truck rack.
