Abstract: This utility model involves with technical aspect in relation to headphones. To specify, it refers to a stereophonic headphone plug comprising one stereo pin and one mono pin and with a design that enables the plug to be converted between single-pin and dual-pin usage. One medial conducting spring and a ground-leading spring has been placed by the left and right sides of the mono pin of this utility model. When the utility model is at dual-pin usage, the grounding of the stereo pin and mono pin is separate. While the mono pin is folded away from the stereo pin to the end, the internal conductor of the mono pin together with the medial conducting spring and the lead contact the medial conductor of the stereo pin.        The external contact of the mono pin connects to external contact of the stereo pin via the ground-leading spring and the lead. This completes the change of the plug from dual-pin usage with separate ground to single-pin usage with common ground. This utility model is user-friendly with its simple structure.

Title: Bale unloading arrangement of a large round baler
Inventor: DERSCHEID DANIEL ERIC
IPC: A01F15/07
Filed: 2003-11-26
Granted: 2007-09-11
Abstract: A bale unloading arrangement of a large round baler includes a bale take-up device mounted to a carrier which is in turn mounted to the axle of the baler for vertical pivoting movement beneath the baling chamber of the baler. A spring is mounted between the carrier and the axle for keeping the carrier in an elevated position until a completed bale is discharged onto the carrier. The carrier is shaped such that the bale take-up device, which is mounted for movement along the carrier, moves down the carrier to the rear and into a position for gently depositing the bale on the ground. The bale take-up device includes an upper bale-receiving structure that may be selectively pivoted about a fore-and-aft axis so as to deposit a bale on its end, and the carrier is mounted for being shifted sideways so that a bale deposited in this manner may be deposited outside the path traveled by the baler.

Title: Procede et appareil pour le montage etanche, avec expansion, de structures tubulaires concentriques
Inventor: WOODS ROSS S
IPC: E21B17/08
Filed: 2001-10-03
Granted: 2009-11-17
Abstract: L'invention concerne un appareil et un procédé permettant le montage étanche d'un premier élément tubulaire en un emplacement fixe par rapport à un second élément tubulaire concentrique. L'élément tubulaire intérieur est configuré de manière à présenter un enfoncement annulaire creux dans la paroi du tube à l'emplacement du matériau d'étanchéité, de telle sorte que la paroi de l'élément tubulaire intérieur pénètre dans le passage cylindrique à l'intérieur du tube. Sur la surface extérieure du premier élément tubulaire, l'enfoncement est rempli d'un fluide partiellement compressible. L'enfoncement annulaire et le fluide partiellement compressible sont alors recouverts d'un manchon malléable/ductile. La mise en place de la garniture étanche nécessite de positionner l'élément tubulaire intérieur dans l'élément tubulaire extérieur et de déplacer le tube intérieur longitudinalement de façon que l'enfoncement annulaire recouvert soit positionné à l'emplacement d'étanchéité voulue. Pour rendre opérante la garniture d'étanchéité, il est nécessaire de diriger un dispositif de déplacement cylindrique à l'intérieur de l'élément tubulaire intérieur vers le point où le dispositif de déplacement rencontre l'intrusion de la paroi du tube intérieur provoquée par l'enfoncement annulaire. Le dispositif de déplacement est forcé au travers de l'intrusion annulaire et repousse vers l'extérieur la paroi du tube intérieur de manière à éliminer efficacement l'enfoncement annulaire tout en alignant la paroi cylindrique du tube afin de permettre le passage du dispositif de déplacement. En même temps, le fluide partiellement compressible se répand sous pression vers l'extérieur, sous le recouvrement malléable/ductile, de telle façon qu'il pénètre dans ledit espace annulaire entre le tube intérieur et le tube extérieur. Cette expansion sollicite le recouvrement malléable/ductile de manière à l'amener en contact avec l'élément tubulaire extérieur, ce contact augmentant dans la zone en question, du fait que ledit fluide partiellement compressible continue d'être pressurisé par le déplacement, dû au mouvement du dispositif de déplacement, de l'élément tubulaire intérieur. Le fluide partiellement compressible présente une énergie résiduelle suffisante pour maintenir l'élément d'étanchéité en contact intime avec la paroi du tubage extérieur.

Abstract: A traffic control system and method, for expediting traffic flow across international border crossings, includes a traffic control center and a virtual traffic lane. The traffic control center is spaced apart from the border crossing, and monitors traffic flow through a border zone. The traffic control center receives border-bound traffic, or electronic information from such traffic, and evaluates it to determine a vehicle's preparedness level. The traffic control center includes facilities for temporarily holding vehicles, and assists vehicles preparing to cross the border. The virtual traffic lane is a preferred route between the traffic control center and the border crossing, and is changeable depending upon traffic conditions. The virtual traffic lane is selected from a number of available monitored routes. The traffic control center monitors traffic conditions in the border zone, and determines which preferred travel route is most appropriate for selection as the virtual lane at any given time.
