    摘要: A process for control of a butt welding of tubes is disclosed wherein readily measurable parameters of a process of welding are read, voltage and current, and parameters such as impedance or time interval across a portion of a pulse are derived from the voltage and current. The derived values are then used in conjunction with parameters of the welding machine to set the values of the welding machine and the torch or torches connected to it to control the power of penetration of a welding arc for no piercing but with penetration.

    摘要: An access unit to a transmission medium formed of two telephone pairs of a local area network with carrier sense multiple access with collision detection, connected to a station containing a send current generator, a receive signal generator and a collision detector receiving the signals sent by the station and every signal sent by other stations. The unit includes a collision simulation circuit receiving a first send voltage U.sub.E and the receive singal V.sub.R, which sends to the collision detector either a second send voltage V.sub.E if the connected station is the only one sending, or the receive signal if the latter is not sending, or a collision simulation signal of which the average value is such that the collision detector signals a collision to the connected station.

    摘要: A liner for a deflection yoke assembly for a CRT includes four substantially equally spaced inclined semicircular channel-like mounting studs, arranged about the circumference of a band-like ring about the front of the liner. Threaded sleeves are push mounted upon and ultrasonically welded to an associated mounting stud. Hollow alignment bolts are screwed into each threaded sleeve, and adjustably positioned relative to the cone of a CRT for aligning the yoke to its associated CRT.

    摘要: A hearing assistance system and method for wireless RF audio signal transmission from at least one audio signal source to ear level receivers, wherein a close-to-natural hearing impression is to be achieved. At least one parameter of the RF signal as received from a transmission unit at a respective receiver unit to create left ear RF signal measurement data and right ear RF signal measurement data, respectively. The angular localization of each transmission unit is obtained by comparing, for each transmission unit, the left ear RF signal measurement data and the right ear RF signal measurement data. The audio signals are processed and distributed according to the estimated angular localization of each transmission unit in a manner so that the angular localization impression of the audio signals from each transmission unit as perceived by the user corresponds to the estimated angular localization of the respective transmission unit.
