Abstract: Paperboard sheets are fed by a feeder including driven wheels which engage the lowermost sheet of a stack and drive it through the nip rolls of a box-finishing machine in synchronism with the latter. Supporting the sheets is a grate moveable between a raised position wherein the wheels are spaced from the sheet and a lowered position wherein the lowermost sheet engages the wheels and is fed thereby to the nip rolls. Below the grate is a vacuum box for holding the sheet on the wheels. Raising and lowering of the grate is effected by a cam which may be adjusted to vary the feed stroke in accordance with the length of the sheets. For driving the wheels there is provided a dual input drive mechanism including a constant velocity such that when the wheels initially engage the sheet, the wheels are at nearly zero or absolute zero velocity and subsequently the wheels reach a constant velocity for driving the sheet at said constant velocity which is matched with the surface velocity of the nip rolls.

Abstract: A methodology for process modeling and control and the software system implementation of this methodology, which includes a rigorous, nonlinear process simulation model, the generation of appropriate linear models derived from the rigorous model, and an adaptive, linear model predictive controller (MPC) that utilizes the derived linear models. A state space, multivariable, model predictive controller (MPC) is the preferred choice for the MPC since the nonlinear simulation model is analytically translated into a set of linear state equations and thus simplifies the translation of the linearized simulation equations to the modeling format required by the controller. Various other MPC modeling forms such as transfer functions, impulse response coefficients, and step response coefficients may also be used. The methodology is very general in that any model predictive controller using one of the above modeling forms can be used as the controller.

Abstract: A bag filling and sealing machine includes a bag holder, a bag opening and filling station, and a sealing station. The bag holder holds wicketed bags in a manner that allows the bags to be easily torn from the holder. A funnel assembly successively opens each bag, tears the bag from the bag holder, fills the bag with material, and releases the bag to a grabber assembly. The grabber assembly engages the sides of the bag while the bag is attached to a funnel assembly and later pulls the sides of the bag away from each other so that the top of the bag is closed and ready to seal when the bag is delivered to a sealing apparatus. The grabber assembly moves in a manner so as to minimize the lost height when moving from the filling station to the sealing station.

Abstract: A method for interfacing components includes receiving a request for an access operation, and determining whether data corresponding to a requested data address is missing from memory, such as cache. Data may be converted from a first communication type to a second communication type and written to the memory and to a second one of the components during a write operation, and converted from the second communication type to a first communication type and read by the first component during a read operation. The components may be an integrated device electronics (IDE) hard disk drive and a system or controller originally designed to communicate with a modified frequency modulation (MFM) hard disk drive. Handshaking signals such as index and seek-complete signals allow the interface module to emulate operation of an MFM hard disk drive. Method for writing and reading a serial data stream to and from a component associated with a parallel data stream are also described.

Abstract: A disk drive mounting system for isolating a disk drive assembly from machine vibration and shock. In one embodiment, the system includes a suspension frame and a disk drive assembly mounted to the frame using biased vibration isolation members, such as springs, which are each substantially aligned through the center of mass of the disk drive assembly. Accordingly, vibrational forces can be transmitted through the center of mass of the disk drive assembly. Preferably, the disk drive assembly includes a mounting chassis which holds a hard disk drive and includes openings through which damping bumpers can extend. In this embodiment, the bumpers each have a base portion and an extension portion, the extension portion extending through the openings in the mounting chassis to limit the transfer of shock to the disk drive. The bumpers can be attached to the suspension frame and/or to a protective cover for the assembly.

Abstract: A technique to provide dynamic modeling, parameter estimation and optimization for processes having operating targets. The technique has an optimization cycle and a simulation cycle. The simulation cycle runs at a rate that is equal to or faster than the run rate of the optimization cycle. Both cycles obtain data from the field about the process. The optimization cycle provides a simulation execution of a dynamic process model and the results of that simulation are used to match the model response to the actual plant response. This matching determines if a dynamic parameter estimation and data reconciliation is needed for the model parameters. Optimized operating targets are determined using either the estimated and reconciled parameters and data or if the same is not needed the collected process data. Mathematical and heuristic assessment tools are used to determine if the optimized operating targets should or should not be invoked.

Abstract: The invention is particularly useful for accumulation conveyors. An assembly located beneath its corresponding zone of item transporting rollers activates the item transporting rollers by lifting the accumulator's narrow belt to engage the underneath side of the item transporting rollers. Electric actuation rather than the traditional pneumatic actuation activates the assembly's vertical movement toward its corresponding zone of item transporting rollers. Whether activated or not, the assembly's rack journals a plurality of pressure rollers that remain contiguous with the narrow belt. Centering of the sideways movement of the narrow belt as the belt travels about the rack is associated with either a pivoting tracking roller journaled in the rack or a flanged pressure roller or rollers channel in the rack. A constant force takeup can be supplied to the belt.

Abstract: A double throw switch linkage for coupling two switch apparatuses together in an enclosure. Each switch apparatus is coupled to the switch mechanism having a switch mechanism lever arm. When the lever arm is moved it translates a force to the actuator plate which closes one switch mechanism and maintains the other switch mechanism in an open position.
