Title: Method and device for manufacturing a cored yarn.
IPC: D01H7/92
Filed: 1984-05-18
Abstract: In a torsion apparatus (4) a torsion is imparted to a slubbing (1) provided from a roving frame (2). Parallel and appropriately orientated fibres (F) are applied to the rotating slubbing (1) to surround it. Owing to those fibres (F), the torsion of the slubbing is not completely lost after the torsion apparatus thereby allowing to obtain a high strength yarn (12). A rotary application member (8) which supplies the fibres (F) to the slubbing (1) comprises a perforated annular fibre supporting surface (9) behind which a vacuum is maintained. The parallel and properly orientated fibres are provided from a second roving frame (10) parallel to the first roving frame (2) and are deposited on the annular perforated fibre supporting surface (9). When the rotating slubbing (1) is in contact with the surface (9), it draws the fibres (F) from said surface (9). In order to keep the fibres (F) parallel and orientated when they are deposited on the slubbing (1), the speed of the annular perforated fibre supporting surface (9) is higher than the supply speed of the second roving frame (10) and smaller than the peripheral speed of the slubbing (1).

Title: Contact end for a welding electrode.
IPC: B23K9/28
Filed: 1986-02-14
Abstract: A contact tip for supporting a consumable welding electrode and for supplying welding current thereto. The contact tip is generally rod-shaped and has a passage with a helical contact surface. The welding electrode is fed through the passage and makes electrical contact with the contact tip. Because of the helical contact surface, the passage never becomes constricted by cumulative deposits of dirt and extraneous matter from the welding electrode surface. Also, the helical contact surface, which axially extends at least one complete turn, has an unbending effect on the welding electrode, thus straightening the electrode. A distance "A" of the electrode axis from the contact tip axis may be chosen, as desired, considering the diameter of the welding electrode. Optionally, the contact tip may include a sleeve-like nozzle, to shield the contact tip from deposits of welding splatter.
