Abstract: A drive shaft (2) rigidly carries disks (4) through which parallel and eccentric hammer carrier axles (6) pass. Between the disks (4), hammers (7) are mounted pivotably about the hammer carrier axles (6). Protective covers (8) cover the disks (4) and the inter-disk spaces not occupied by hammers. Each cover (8) has the form of a sector of cylinder terminating in rims (11, 12) facing the drive shaft (2) and engaged in notches (13) of the disk. On a disk (4) two consecutive notches (13) between them define a dovetailed boss and form a retaining and guiding shaped portion avoiding the use of screw fastenings and serving as a slideway during assembly.

Abstract: An intermodal road/rail transportation system wherein the freight containers or road trailers are adapted for transportation on detachable rail trucks or bogies. The system includes various bogie constructions, locking devices and trailer constructions which obviate the disadvantages of the prior art by, among other things, absorbing and/or minimizing the various stresses applied to the system. In the rail mode, the system allows the sequential starting of rail cars, thereby reducing the force necessary to start a string of trailers. The system also includes a variety of compatibility components to allow use of the system with other dissimilar intermodal or bimodal systems and/or conventional locomotives and freight containers.

Abstract: The armor comprises a plate of refractory steel (1) resistant to cracking by means of a known torch. One or more inserts (2) of refractory material resistant to an added metal torch are encased in the refractory steel (1), the structure and distribution in the interior of the steel of this insert or of these inserts (2) being such that the plate comprises a series of zones, distributed over the whole of the plate, which are separated by zones in which the thickness of the steel is different. Application particularly to safes.
