OOOPs you are right! I was looking for a shortcut to avoid to copy a lot of data. A correct list can be found searching Carnacina in www.google.com/patents. Here i'll copy first occurrencies:

Patent:US3495529 - Filed Mar 7, 1968 - The National Cash Register Company
Patent:US3311300 - Filed Jul 22, 1964 - The National Cash Register Company
Patent:US3241756 - Filed Apr 6, 1964 - Monroe
Patent:US3130904 - Filed Oct 19, 1959 - Walther Buromaschinen
Patent:US3384301 - Filed Dec 23, 1966 - Intern. Business Machines Corporation
...

Mainly these are references quoted by the reviewer. But I consider quite surprising that a commercial "flop" has been used as comparation for patents released to greatest producers. Celli 22:13, 11. Mar 2008 (GMT)

I seen the folder containing the original Carnacina patent for a printing calculator. It was registered in 1952. But, since 1954, the annual fees was payed bye NCR. Then we can suppose that NCR acquired the patent and, possibily, that they acquired also I.C.S. Celli 23:04, 3. Mag 2012 (CEST)
