The invention relates to a method of welding together (joining) parts of composite materials which each consist of a parent material (1) and an overlay material (2), the parts being connected at their margins by a weld (1a, 2a) made by the beam welding method. In order to avoid the development of mixed structural zones, a channel-like recess (7) is formed in the parent material (1) and/or overlay ...

Two winding spindles (5.1, 5.2) are mounted on the bobbin turret (18) of the winding machine. The particular winding spindle which is in operation bears with its bobbin against a contact roller (11). With an increase in bobbin diameter, the bobbin turret (18) is rotated in dependence on a slight deflecting movement of the contact roller (11). The position of the contact roller remains essentially ...

The object of the invention consists in a compacting process in powder metallurgy for preparing powders to sintering operations, in which process the powders, after mixing the same with solid lubricants and liquid solvents, are preheated up to a temperature between the room temperature and the softening temperature of the lubricant employed.

A method of clamping an annular tread to a pneumatic tire casing comprises mounting the casing on a wheel, mounting the annular tread on a tread expander assembly. The assembly expands radially and stretches the tread to a size allowing the tread to circumferentially surround the casing. The stretched annular tread then is moved axially toward the casing to a position where it circumferentially su...

The umbrella/sunshade proposed has a shade (8) supported by struts (4) mounted in hinges in a fixation head (6) fitted on a central stand (1, 2) connected by hinged cross-struts (5) to the struts (4).
