Abstract: Apparatus for providing electronic data associated with an item to a user, the apparatus comprising a memory tag scanner arranged to communicate with a memory tag associated with an item, a user profile memory arranged to store user profile data therein, an output interface arranged to provided data to a user, and a data processor arranged to cause data to be selectively read from the memory tag associated with an item and the data to be selectively provided to a user via the output interface in accordance with the stored user profile data.

Abstract: Hydrolysis of COS in gas streams to H.sub.2 S and CO.sub.2 can be improved by the addition of certain bicyclo amine catalysts to acid gas removal solvents.

Abstract: A rate/time control device for computing an activity period. The control device includes a clock for generating a representation of present time and an element for storing a start time therein. A first input element provides an input to the storage device from the clock representative of the start time. A first output element is provided for receiving an output from the storage device representative of the start time. A time computer is included for computing the activity period by subtracting the start time from the present time.The control device further includes a rate selector and a charge computer for calculating a monetary charge for the activity period by multiplying the rate by the activity period. A plurality of the control devices may be coupled together to allow one control element to operate a plurality of units.
