Patent FR-2546800-A1 (FR)
Title: Wrench for nuts with restricted access
Inventor: FASTERLING KARL
IPC: B25B13/48
Filed: 1983-12-06
Abstract: The jaws (11,13) of the wrench are connected with the operating assembly at an angle of 92 degrees. The two degrees additional to the perpendicular result in an increased ease of application for extremely restricted accessibility and in an improved gripping effect. A tube (12) is welded to one of the jaws and a shaft (10) fitted rotatingly inside the tube. At the other end the tube is connected to a handle (17) and the end of the shaft slightly protruding from the end of the tube is connected to a handle (15). By turning the two handles towards and against each other, a corresponding gripping motion of the two jaws (11,13) is achieved.

Title: Dismantleable and modifiable boat made from assembling several non-sink modules
IPC: B63B7/02
Filed: 1984-03-21
Abstract: Method of construction of a river boat. The invention relates to a method of construction of river boats allowing the production of units of variable length by assembling, in a rigid but removable manner, floating and non-sink modules. Each module is composed of a float assembly 29 and a habitation cell 28 permanently attached. The float assembly 29 of the catamaran type has a shape similar to that of a W. The ends of the floats are closed by panels 20 and 23 in a more or less vertical plane and have male and female fittings 30 and 31 ensuring the rigidity of the boat. The habitation cell is formed by an undeformable wooden framework covered by an exterior coating. The wooden framework of the cell is perforated in several places on the two assembly faces in order to receive connecting bolts. The joining of the modules thus produced is achieved simply by fitting and bolting in order to make construction and modifications easier.
