log cabin is a small house built from logs. It is a fairly simple type of log house; they were built both in rural areas and in cities in timber-rich regions, around the world, but particularly in the northern hemisphere.

Log structures in the US were first constructed by Swedes in what is now south-east Pennsylvania, c. 1638,and as such were not used by the first English settlers in the United States. There are few log cabins that date from the 18th century still standing in the US; most were not intended as permanent dwellings and as time passed they were often converted into out buildings for coops, animal shelter or other utilitarian uses. When cabins were built with the intention of applying siding, the logs were usually hewn on the outside to facilitate the application of the siding. When logs were hewn on the inside as well they often were covered with a variety of materials, ranging from plaster over lath, or wallpaper. Paragraph cited from Wikipedia: Huts

In the figures above you will find some illustrated and detailed examples of machines and processes. A patent specification must be described in detail, so that a technician can rebuild and copy it. Patent specifications are always the first publications of innovations, often long before the products are sold. In addition this patent collection is a pool of innovative ideas for your own usage. Of course these products may only be used in an unchanged form for private use and not for commercial purposes. The detailed described trains of thought of the inventors train the own spirit, perhaps for your next "invention". Profit from this knowledge.

Normally only companies can afford extensive patent searches, like offered here. The compilation of such collections in well archivable format is complex and requires commercial data base programs. Some American companies want US$ 3.50 per patent! Our publishing house offers these achievements to you for an unbeatably low price. If you miss an interesting topic, ask us and we will make an item an offer it here on eBay, which you cannot say "no" to (however only for private and not commercial purposes, for firms we have other conditions (inquiries requested)).

If no particular language is specified in the description, then the collection can have patents in English, German, French or other languages.
