JK: To help you along in your JPO searches.
In regard to the last item listed (349 patent-no title available), as I noted before because of its age the application is not in the PAJ data base; however, patent details are in a separate data base. To access this data base, click on Patent and Utility Model Gazette DB rather than PAJ. For Kind Code enter "B" for patent, and then the patent number "2816349". On the resulting page click the number that shows in the left side column, a detailed description of the patent including drawings will come up. (note: for applications that are in the PAJ, if you want this detailed information, just click the detail button on the application information page.)
