Abstract: The disclosure relates to a remote displacement sensor, such as an optical strain gauge, which uses an optical amplifier implemented by patterns, such as, moiré patterns, to calculate changes in position. In a strain gauge with moiré patterns, two foil layers are provided, a lower foil layer with a reference or static moiré pattern generated by the overlaying of a first pattern with parallel lines at a first fundamental frequency and a second pattern with parallel lines at a second fundamental frequency. The lower foil layer further includes a first section with a first pattern with parallel lines at the first fundamental frequency while the upper layer provides a second section with a second pattern with parallel lines at the second fundamental frequency. The overlaying of the foils causes an overlying of the first and second sections thereby causing a moiré pattern of the same wavelength as the reference pattern.

Abstract: The disclosure relates to a remote displacement sensor, such as an optical strain gauge, which uses an optical amplifier implemented by patterns, such as, but not limited to, moiré patterns, to calculate changes in position or gauge length. In the embodiment implemented as a strain gauge with moiré patterns, two foil layers are provided, a lower foil layer with a reference or static moiré pattern generated by the overlaying of a first pattern with parallel lines at a first fundamental frequency and a second pattern with parallel lines at a second fundamental frequency. The lower foil layer further includes a first section with a first pattern with parallel lines at the first fundamental frequency while the upper layer provides a second section with a second pattern with parallel lines at the second fundamental frequency. The overlaying of the foils causes an overlying of the first and second sections thereby causing a moiré pattern of the same wavelength as the reference pattern.

Abstract: A collator includes a first conveyor having a discharge end and a second receiving conveyor positioned below the discharge end of the first conveyor. As each product bag falls toward the second conveyor, an air blast assists in uprighting the bag. The second conveyor may be temporarily operated at a high speed to separate the product bags into groups. A deflector may be mounted at the discharge end of the second conveyor for directing product bags into containers. A diverter may be used to direct incoming product bags between parallel conveyors.

Abstract: A collator includes a first conveyor having a rotatable drum positioned at its discharge end. The rotatable drum is comprised of a plurality of disks. Two pairs of air nozzles are positioned between the rotating disks of the rotatable drum. A second receiving conveyor is positioned below the discharge end of the first conveyor. Bagged products move along the first conveyor and are discharged over the rotating drum of the first conveyor. As each product bag falls toward the second conveyor, an air blast assists in uprighting the bag. A sensor indicates that the product bag is properly positioned for uprighting by the air blast. A programmable logic controller ("PLC") which controls the operation of the collator in accordance with the size of the product bags.
