The reinforcing walls are each formed with communication holes for causing the parallel refrigerant passages to communicate with one anther therethrough. The flat aluminum tube is prepared from upper and lower two aluminum sheets by bending opposite side edges of the lower aluminum sheet to a raised form and joining the bent edges to the respective side edges of the upper aluminum sheet which is flat so as to form a hollow portion. The reinforcing walls are formed by joining to the inner surface of the upper wall ridges projecting inward from the lower wall.

| 137 | Method of production of anchor-bonded composite structures | US622340 | 1990-11-29 | US5121537A | 1992-06-16 | Shigetomo Matsui; Toshio Atsuta; Takeshi Yamada; Yasuhiro Kumon; Makoto Ryoji; Toshihiko Ishizuka; Hiroatsu Asari; Shigemi Murakami |
| A method of producing an anchor bonded composite plate. Anchor cavities are formed in a base plate by placing a forming plate with a circular hole therethrough over the base plate at a selected anchor cavity location. A punch placed through the circular hole then applies a punching force to the base plate, thereby forming in the base plate an annular mound with a concentrically punched hole. The mound is next pressed with a leveling plate to cause the material of the mound to flow inside the punched hole forming an anchor cavity with an overhanging internally tapered surface. A cladding plate with a plurality of anchor holes is then placed on the base plate with its holes aligned with the cavities of the base plate. An anchor pin is inserted in the thus aligned openings and is plastically deformed to mechanically bond the plates together. The cladding plate and the base plate may be made of an aluminum alloy and a hard steel, respectively. The composite plate thus produced is applicable as a reaction plate for a linear motor vehicle and as a tank material for a liquid natural gas holder. | ||||||

| A method for making multi-colored composite laminates comprises stacking a plurality of colored strips in a predetermined pattern and bonding the strips into a composite laminate by continuous bonding. The composite laminate is then rolled before being passed through a deep steel pattern roll which forms a raised pattern on its surface. Next, the laminate is passed through a skiving table where the raised pattern is skived off to expose the multi-colored pattern formed by the underlying layers. The laminate is than flat rolled to a finished dimension and may be reeled up into a cylindrical roll. | ||||||
| 139 | Method of profiling metal strips | US634174 | 1984-07-24 | US4598564A | 1986-07-08 | Kurt Held |
| In profiling the surface of a metal strip, particularly pressed strips for use in double band presses, the pressed strip is provided with graduations on a surface outside of the surface to be profiled. The graduations on the strip correspond to graduations on a tool used to profile the strip surface. With the graduations on both strip and tool in register, synchronized movements of the strip and the tool is effected with the strip being rolled into surface contact with the profiling surface of the tool so that the profiling surface of the tool is reproduced on the strip. | ||||||
