A device for jointing, by means of compressed air, textile yarns and for preliminarily preparing the ends of the yarns to be jointed is provided, in particular for being installed on textile machinery, such as spoolers. In order to achieve minimum overall dimensions of the device, and to the purpose of constructing it in a simple and cheap way, the device comprises a central body (10, 11, 12) bear...

A line pressure (PL) is adjusted based on data which are updated after evaluation of an intertia phase time of a previous shifting in comparison with a predetermined value. Thus, during the next shifting of the same kind, a shifting friction device is engaged by the line pressure (PL) which has been properly adjusted, thus assuring shock-free shifting irrespectively of manufacturing variations and...

A device for cutting moving material webs, especially of fibrous materials, to shape comprises a rotating shape cutting roller and a rotating counter cutting roller. The shape cutting roller has a shape cutting side and the counter-roller a smooth surface. Both rollers are borne in a machine frame by means of rotary bearings and the center distance between them is adjustable. The rollers are rotat...

A simplified process is disclosed for making form fitting undergarments that include structures for absorbing (13) and containing body exudates. The garments are formed by selectively cutting (14, 15) and seaming (17, 18) sheets (8) having parallel elastic strands into trapezoidal or rectangular geometries so that the finished garmet when stretched in the waist at least 70 % contracts in the perpe...

The described device comprises two primary pliers systems (2, 2a) arranged to engage through respective gripping elements (25, 26) the opposite ends of an elastomeric filler (45) applied on the bead core (46). The pliers systems are pivoted around an axis a little far, toward the center of the bead core, with respect to the convergence point of the V-shaped opening formed by the ends of the filler...

A method of testing security papers with respect to the positions of a safety thread and water marks to detect errors in the paper is performed by a linewise scanning of a finished paper web. The web has at least two point like measuring marks inserted into it in addition to the water marks, whereby impulses which are originated from these measuring marks are evaluated and the sheet width and the ...

A method and apparatus used to detect errors in a signal transmitted over a single wire. All transient errors are detected when the effect of the transient lasts for at least one cycle and not more than five cycles. Transient errors of longer duration will be detected if the level of the original signal at the start of the transient is different from that at the end of the transient. Stuck faults ...

A test sample color comparison device is disclosed which has a casing unit with an insertion slot for inserting a color test sample therein, and a display section for displaying the color test sample adjacent at least one of a plurality of reference color shades, as the reference color shades are successively moved into position adjacent the color test sample by a manipulation wheel. When an opera...

A teeming spout has on its inside a plurality of picket-like metal segments (1) separated from one another by slots (2) and is externally surrounded by an induction coil (3). The bottom turn (7) of this induction coil (3) has a downwardly directed pitch equalization piece (8) which provides such that the field acts uniformly on the teeming stream from all sides and therefore it is not deflected.

An arrangement comprising a laser beam receiver and a canal building laser device is intended to be disposed in a pipeline. The canal building laser device is located in a shaft at the beginning of the pipeline and the laser beam receiver is located at the end of the portion of the pipeline produced, for example, the previous day, in the region of a still open pit. Owing to the distance from the l...
