A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. The method includes the step of providing a tube and the step of coating the tube with polyurethane resin in order to provide a cushion on the tube. Upon detecting the absence of the allocated CQICH, the MS sends a request for allocating the CQICH to the target anchor BS. The blade forms, in a cross section perpendicular to the lengthwise direction and through the junction, a maximum thickness location between the leading and trailing edges, the maximum thickness location being where the distance between the windward and leeward outer surfaces is larger than at any other location in this cross section. The encoder forms a first packet of code symbols, having a first code rate, based on bits from the first output bit stream. In one embodiment, a separate display of the cleared balance is provided, a single link button is provided to enable the upload of the register contents to a computer for reconciliation or for archiving and a memory attachment, such as a USB memory key, is also provided for archiving andor additional program capabilities.
