摘要:
A dual-stream filling system is used in a packaging machine to introduce at least two flowable materials into a plastic bottle. The dual-stream filling system defines a material flow path therethrough. The system includes a primary filling tube having an inlet end and a discharge end and defining a primary filling tube internal flow region. A secondary filling tube has an inlet end and an outlet end and defines a secondary filling tube internal flow region. The secondary filling tube is positioned at least in part within the primary filling tube internal flow region, penetrating the primary filling tube through the first opening. The dual-stream fill system includes a valve plug that includes a portion that is movable relative to the secondary filling tube between an opened state wherein flow communication is established between the internal flow regions of the primary and secondary filling tubes and a closed state wherein flow communication is terminated between the internal flow regions of the primary and secondary filling tubes. An actuator is provided for moving the valve plug portion between the opened and closed positions. The actuator is disposed fully external of the secondary filling tube flow region.

An in-line, lever actuated valve for use in a liquid filling apparatus includes a valve body having an outer surface and defining an inlet region, an outlet region and a flow chamber intermediate the inlet and outlet regions. The valve body defines a cone opening in a side wall of the valve intermediate the inlet and outlet regions. A pivotable cone member having a plunger, a lever arm and a cone shield intermediate the plunger and lever arm, is positioned with at least a portion of the cone member traversing through the cone opening and positioned within the flow chamber. The cone shield engages the outer surface of the valve body to form a seal therewith. The cone member is pivotable through an angle of about 20.degree. from an opened position to a closed position wherein the plunger forms a seal across the flow chamber. The cone shield is positioned on the lever so as to define a base angle that is about one-half of the angle that the valve cone pivots from the closed position to the opened position.

First and second disc drives which respectively read first and second discs on which signals are digitally recorded perform multiprocessing of each disc's signals by a single demodulator circuit based on commands from a host device. In this way, the single demodulator circuit is shared by the first and the second disc drives, and each disc drive can be used in the same way as two independent disc drives.

An automated sealing apparatus for sealing a packaging machine cleaning environment is set forth. The apparatus includes a retractable cover having first and second ends. The first and second ends of the retractable cover are disposed perpendicular to a direction of movement of the retractable cover. The apparatus further includes a first securing device disposed on the first end of the cover and a second securing device disposed on a top of the cover near the second end of the cover.
摘要:
An image reading apparatus for reading an image of a document by dividing the image into a plurality of sections in the main scanning direction and causing independent solid-state imaging devices to read those image sections. A displacement of the document from a correct reading position is detected. An effective pixel area for reading of each of the imaging devices is varied on the basis of the detected displacement of the document.
