Abstract: A cleaner assembly for an apparatus for making pouch products includes a cleaner roller and a poker roller. The cleaner roller may counter rotate with a rotatable drum of the apparatus, in contact with an upper surface of a first elastic layer on the rotatable drum, and at a greater tangential speed than at least one surface of an outer circumferential surface of the rotatable drum or an upper surface of the first elastic layer. The poker roller includes projections that are each configured to extend into one or more divots of the rotatable drum. The poker roller may counter rotate with the rotatable drum and at a same tangential speed as the at least one surface such that the projections extend into and out of separate, respective divots of the rotatable drum based on the counter rotation of the poker roller and the rotatable drum.

Abstract: A method and apparatus for controlling a centrifuge system, the centrifuge system including a rotor and a motor operatively coupled to the rotor, the apparatus including an accelerometer coupled to the centrifuge system so as to measure an acceleration of at least a portion of the centrifuge system during operation of the centrifuge system to provide an acceleration signal, a filter that receives the acceleration signal and provides a filtered acceleration signal, and a controller that receives the displacement signal and controls the centrifuge system in response to the displacement signal.

Abstract: In a magnetic resonance imaging system in which the read and phase directions are rotated with respect to the orthogonal gradient coil directions, a gradient coil is driven to generate a gradient waveform having a segment, either sinusoidal or linear, that approximates the sum of the simultaneous non-zero components of the read and phase gradient waveforms in the direction of the gradient coil. Resonant circuits, each including a gradient coil, generate simultaneous periodic gradient coil waveforms in which the integral over each waveform period is non-zero. First and second capacitive elements in the resonant power supply are electrically connected to the gradient coil through a switch and a bridged network, respectively. The bridged network selectively provides current flow paths between the coil and either of the terminals of the second capacitive element.
