Description: I offer a collection of 130 patents from Magnus Niell (constructeur of the Ensign), Georg Houghton, Houghtons Ltd., Houghton Butcher Company or Barnet Ensign Ltd., published between 1894 and 1956. They are from USA and Great Britain (all in english) and busy with camera technique (like Ensignette) or parts of it. All patents are complete, that means contain the full text and all drawings (see example). You will get a professional overview about the technical developments of Niell, Houghton and the companies which you find nowhere in the world in this good quality / completeness. You can learn a lot about the technical details of old camera technique. Delivery is as a zipped file with a patent collection of pdf files (not printed, not a book). You need only the wellknown free programme Acrobat Reader or a similar one to open the files. You can also print each file. Also included is an Excel list with patent numbers, datas of issue, inventors and patent titles. The list is linked directly to each patent file so that each patent can be opened very easy if you click on the link. This is a very comfortable way to exploit the extensive document material. It is not really a problem if you do not have the programme Excel from Microsoft. Look for "Excel Viewer" at google and you will find freeware version of an Excel Viewer programme. So you can open and print the Excel table without problem Of course you can open each patent file also direct without using of the Excel table! Copyright of the patent collection has only the seller!
