An assembly line system comprising including a programable controller, a priority component, a first section upstream of the priority component that includes upstream backup detecting sensors, and a second section downstream of the priority component that includes downstream backup detecting sensors. In operation, the programable controller identifies whether there is a backup in the first and/or second section from a current status of each of the upstream and downstream backup detecting sensors and alters an operating speed of the priority component responsive thereto so as to avoid micro stops of the priority component.

A system for conveying proppant includes a conveyor assembly having a conveyor belt that receives proppant from one or more containers having proppant stored therein. The system also includes a conveyor auxiliary unit connected to an end of the conveyor assembly having one or more joints to enable expansion and collapse of the conveyor belt from the conveyor assembly. The system further includes a proppant chute to direct the proppant from the conveyor belt into a blending hopper, the proppant chute being positioned at a higher elevation than an inlet of the blending hopper.

A method for ascertaining a position error in a linear drive, a linear drive, a method for operating the linear drive and an installation, wherein the deviation of a respective further runner in relation to a first runner (reference runner) is ascertained to determine the position error, where the discrepancy of the respective sensor is ascertained based on the deviation of the runner, the discrepancy may be ascertained using a reference system, the position error may be established based on the discrepancy of the respective sensor PS and the deviation of the respective runner, and where the position error may serve for the improved positioning, i.e., more precise positioning, of the respective runner on the linear drive or of the segments.

A conveyor system for luggage or parcel items comprises an item conveyor for conveying the items and an aligner for aligning the items, the aligner comprising alignment means, such as tilted or slanted belts capable of changing an initial orientation of an item to a subsequent orientation of the item while the item is being conveyed along a general conveying direction of the aligner. A control system is provided for controlling the first and second conveyor elements which are arranged alongside each other and capable of simultaneously engaging an item engaging surface of the item, and individually controllable by the control system to convey at individual speeds to effect rotation of the item around an upright axis.

A portable multi-sectioned boom concrete conveyor assembly that includes a feeder conveyor configured to transport a construction material toward a distal end of the feeder conveyor and a main conveyor boom assembly including a plurality of main conveyor boom sections. The plurality of main conveyor boom sections may include a proximal main conveyor boom section and a distal main conveyor boom section that is rotatably coupled to one of the plurality of main conveyor boom sections about a revolution joint, has a second main conveyor belt spanning from a first end of the distal main conveyor boom section to a second end of the distal main conveyor boom section, and is operably configured to independently revolve approximately 360 about the revolution joint. The first and second main conveyor belts are operably configured to transport the construction material toward the second end of the distal main conveyor boom section.

A control system, apparatus, and method for controlling operations of a milling machine are described. Data corresponding to a ventilation mode and a conveyor delay amount set by an operator of the milling machine is stored in memory. Control of transition of operation of the milling machine from a milling mode to a standby mode is according to a first predetermined sequence of operations responsive to a first input at a control panel of the milling machine. Further, control of transition of operation of the milling machine from the standby mode to the milling mode is according to a second predetermined sequence of operations, which is in reverse order relative to the first predetermined sequence of operations, in response to the first input at the control panel.
