One of the improvements of the invention consists in the insertion, into a device such as that of patent No. 556,542, of a sealing cartridge, with memory and "intelligence", in the data output connector, suitably protected by, for example, a cover with lock. The connector will have a reader and/or a data input part or, alternatively, there will be another, different connector or input (also protected) into which said cartridge or card will be inserted in such a manner that during each operation of machine the cartridge is read and, optionally, the information it contains is modified and/or updated. The improvements are supplemented by means of the incorporation of visual or acoustic indicators of the reserve situation, the physical support being provided with a non-erasable identification and/or with space for data, and/or for disconnecting its large remainder in the following load (charge). <IMAGE>
