Abstract: A palletizer for picking up a group of stacked cans from a first pick-up position on a conveyor, transporting the cans to a second deposit position and depositing the cans onto a pallet. The stacks of cans are accumulated on the conveyor by an exit gate prior to being picked up. The cans are also aligned on the conveyor by means of a retractable can guide adjacent the conveyor. The palletizer further includes a transport carriage movably mounted on a track of a frame. The carriage includes both a lift mechanism for lifting the cans off of the conveyor and a hold-down mechanism to steady the cans while they are being lifted and transported to the pallet. Finally a push bar unloading mechanism disengages the cans from the lift mechanism and snugs them against the other cans on the pallet.

Abstract: The disclosure provides an automatic capping apparatus for placing a cap on the opening of a container and crimping the cap onto the opening to seal the container. The capping apparatus includes three operating stations through which the containers are moved on a conveyor -- an aligning station to position the container on the conveyor, a cap pickup and placing station to deposit a cap on the opening of the container, and a crimping station for crimping the cap onto the opening. Furthermore, sensing means are provided at the pickup and placement station and the crimping station to assure that the operation at those stations is successfully accomplished.

Abstract: This invention is a method and apparatus for dispensing a predetermined weight of liquid. The apparatus comprises a calibrated vessel having an elongated tubular section in open communication with the top of the vessel, means to fill the vessel to a level in the elongated tubular section, a displacement means which provides an area of reduced cross section at the liquid level in the tubular section, means to monitor the temperature of the liquid, means to adjust the position of the displacement means in response to temperature changes of the liquid and means to dispense the liquid. The apparatus can dispense a predetermined weight of liquid over a broad temperature range. The method comprises the steps necessary to dispense the predetermined weight of liquid.
