A welding or additive manufacturing wire drive system includes a welding wire spool and first and second drive rolls. One or both of the drive rolls has a circumferential groove. The system includes a first welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove, and a second welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove, and the second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.

Welding or additive manufacturing dual wire drive system

A welding or additive manufacturing wire drive system includes a first spindle for a first welding wire spool, a second spindle for a second welding wire spool, a first drive roll, and a second drive roll. One or both of the drive rolls has a circumferential groove. A first welding wire and a second welding wire are located between the first drive roll and the second drive roll in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove. The second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.

A welding or additive manufacturing wire drive system includes a first drive roll and a second drive roll. One or both of the drive rolls has a circumferential groove for simultaneously driving both of a first wire electrode and a second wire electrode located between the drive rolls in the circumferential groove. A sensor device generates a signal or data corresponding to a consumed or remaining amount of one or both of the wire electrodes. The first wire electrode contacts the second wire electrode within the circumferential groove. The first wire electrode further contacts a first sidewall portion of the circumferential groove. The second wire electrode further contacts a second sidewall portion of the circumferential groove. Both of the wire electrodes are offset from a base portion of the circumferential groove, said base portion extending between the first sidewall portion and the second sidewall portion of the circumferential groove.

Dual wire welding or additive manufacturing system

A welding or additive manufacturing wire drive system includes a first drive roll having a first annular groove, a second drive roll having a second annular groove, a first welding wire located between the drive rolls in the annular grooves, and a second welding wire located between the drive rolls in the annular grooves. A biasing member biases the first drive roll toward the second drive roll to force the first welding wire to contact the second welding wire. The first welding wire contacts each of a first sidewall portion of the first annular groove, a first sidewall portion of the second annular groove, and the second welding wire. The second welding wire contacts each of a second sidewall portion of the first annular groove, a second sidewall portion of the second annular groove, and the first welding wire. The drive rolls rotate in opposite directions thereby moving the welding wires through the wire drive system.

To position an imaging subject () in an imaging or therapy system (), the imaging subject () is arranged on a linearly translatable tabletop () disposed on a movable trolley (). A position of a region of interest () of the imaging subject along the linearly translatable tabletop is selected using an elongated position selector () that is elongated in a translation direction (z) of the linearly translatable tabletop (). After the selecting, the movable trolley is docked with the imaging or therapy system (). After the docking, the tabletop is linearly translated to move the imaging subject to the imaging or therapy system, the amount of linear translating being based on the selected position of a region of interest along the linearly translatable tabletop.

Off-magnet patient scan positioning

An MRI apparatus is provided. The MRI apparatus includes a main magnet () for generating a main magnetic field in an examination region, a plurality of gradient magnets () for generating magnetic field gradients in the main magnetic field, a radio frequency coil () for transmitting radio frequency signals into the examination region and exciting magnetic resonance in a subject disposed therein, and a radio frequency coil for receiving the magnetic resonance signals from the subject. The MRI apparatus also includes subject support () for supporting the subject, a position controller () for controlling the position of the subject support within the examination region, and a position encoder () for directly measuring the position of the subject support.
