Abstract: A method for regulating the loading of an adjustable-crown roll having a stationary roll axle around which a roll mantle is rotatingly mounted, and by means of which roll a nip is formed with a backup roll. The deflection of the roll mantle and/or the linear load in the nip is regulated by loading elements and a backup zone supported on the roll axle and acting upon the inner face of the roll mantle in the direction of the nip plane. Upon the inner face of the roll mantle of the roll by means of the backup zone/zones, a sum force is produced which acts in the nip plane in a direction substantially opposite to the force produced by the loading element, and the force effect applied by the backup zone/zones to the inner face of the roll mantle is applied, examined in the direction of the circumference, to more than one point. The adjustable-crown roll forms a nip with a backup roll and includes a stationary roll axle around which a roll mantle is arranged revolving, between which roll mantle and roll axle loading elements and backup zones are arranged to act upon the inner face of the roll mantle and are supported on the roll axle. The backup zones supported on the roll axle are formed of at least two rows of backup-zone elements or by a backup chamber or by at least one row of backup-zone elements and a backup chamber. The sum force produced by the elements or chamber in the nip plane is in a direction substantially opposite to the force produced by the row of loading elements.

Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled. The obtained cord (1), within each laying pitch and only under a traction condition involving a load not exceeding 5 kg, has at least one right cross section in which at least one wire (2a, 2b) is spaced apart from at least one of the adjacent wires so as to facilitate the rubberizing step, by enabling access of the blend to the cross section and penetration thereof along the cord axis. The cord is preferably used as a reinforcing element for the belt structure.

Title: Loading software into field test equipment
Inventor: BOMAN BENNY KARL INGE
IPC: H04M3/22
Filed: 1996-01-30
Abstract: In a cellular telecommunications system comprising a base transceiver station (BTS) coupled to a base station controller (BSC), a method for testing the BTS begins by connecting an operations maintenance terminal (OMT) to the BTS, the OMT including a first OMT program for performing a desired test.  A test program version level is sent from the OMT to the BTS.  In the BTS, the test program version level is compared with a BTS program version level.   If the test program version level matches the BTS program version level, then the first OMT program is used to perform the desired test.  Otherwise, a nonmatch procedure is performed.  The nonmatch procedure includes sending a software download request from the BTS to the BSC. In response, a second OMT program is sent from the BSC to the BTS.  The BTS then sends the second OMT program to the OMT.  Then, the second OMT program is used in the OMT to perform the desired test.  The BSC may obtain the second OMT program from an operation support system, so that the fact that a new version of OMT software is being downloaded is transparent to the BSC.  In an alternative embodiment, the BTS always initiates the downloading of the OMT software to the OMT whenever the OMT initiates a test, without the need for comparing test version levels of the OMT and BTS test programs.
