Patent EP-0026043-A1 (EP)
Inventor: YOSHIDA TOSHIO
IPC: B23K20/04
Filed: 1980-08-13
Abstract: An inner stainless-steel tube (2) having an outer frustoconical faying surface (2a) is fitted into an outer carbon-steel tube (1) having a matching innerfrusto-conicalfaying surface, and these tubes are friction welded over their entire faying surfaces by pressing the tubes together in their axial direction to obtain a high contact pressure due to a wedge action and, at the same time, imparting rotation thereto relative to each other thereby to obtain an integrally bonded, laminated,tubular blank, which is then extended by a suitable process such as rolling into a clad steel tube. The tubular blank can also be slit in its axial direction and flattened into a laminated flat blank, which can be rolled into a clad steel plate. The inner tube may be replaced by a solid core metal.

Abstract: Lorsque l'on construit des maisons privees en particulier le transport d'articles tels que des tuiles jusqu'au toit, par exemple, represente un probleme. Les transporteuses produites jusqu'ici avaient une forme determinee, et etaient lourdes et peu pratiques a transporter. La presente transporteuse est legere et prend peu de place lors du transport. La transporteuse consiste en une unite centrale (1) comprenant un tube telescopique qui peut se retracter pendant le transport et s'allonger pour prendre sa longueur totale en fonctionnement. L'unite centrale est pourvue a chaque extremite de deux unites transversales (3L, 1A) sur lesquelles deux bandes paralleles (1E) sont placees, lesdites bandes etant de preference en nylon et etant pourvues de plusieurs poussoirs (3H) disposes les uns apres les autres.
