Title: Machine for forming of seam welded tube - uses pair of rollers to produce range of tube sizes
Inventor: OPPERMANN WILLI
IPC: B21B17/00
Filed: 1973-10-29
Abstract: The rollers are mounted with their axes horizontal in bearings in the uprights mounted on the guide which can slide on the base. Each roller has a number of semi-circular section grooves, each groove being suitable for forming a particular size of tube. The rollers are driven through the telescopic universal jointed shafts. When it is required to produce a different size of tube the guide is moved by the hydraulic cylinder so that the required grooves are in line with the metal strip for making the tube. The time to adjust the machine to produce different sizes of tubes is greatly reduced with this method.

Title: Foamed or cellular metals prodn - from aluminium using titanium hydride, and reinforced with steel inclusions
Inventor: ROCK EDWARD J
IPC: C22C1/08
Filed: 1973-12-14
Abstract: The metal which is to be converted into a foam is mixed with inclusions possessing a higher m.pt. than the metal and with a gas-forming material, the three materials being mixed in >=1 inclined rotary drum provided with an opening at both ends; the three materials are fed in at the upper end of the drum and leave via the lower end. The pref. metal is aluminium with steel inclusions forming up to 35% of the finished product, and using a metal hydride as the gas-forming material. A second, pre-heating drum may be used to obtain molten metal at a temp. below the decompsn. pt. of the hydride so the particles of the latter are coated with metal before entering the drum. A high proportion of inclusions, e.g. steel fibres, can be included in the foam, thus increasing the strength and reducing the brittleness.
