Abstract: A dual cam configuration is provided in a container filler machine. The filler machine preferably fills containers from their bottoms and includes at least one filling station assembly, each such assembly including a dispensing assembly and a positioning assembly. For controlling the filling process at each station, the cam configuration includes first and second cam tracks, each track being followed by a cam following assembly. For each station, the machine also preferably includes a single pneumatic cylinder assembly for simultaneously maintaining both cam following assemblies against their respective cam tracks.

Abstract: A carousel trash compactor for selectively sorting and recycling multi-component refuse. The carousel includes a turntable mounted in the lower portion of the housing and supporting refuse bins rotatable with the turntable to position a selected bin in a refuse receiving position or a refuse compaction position. In the housing upper portion, a stationary compactor mechanism is positioned for compacting refuse in a bin therebeneath. A lid closes an opening in the top of the housing over the refuse-receiving position. A receptacle retrieving subassembly mounted in the upper portion of the housing facilitates removal of a full receptacle from the housing. Automatic control devices are provided for selectively rotating the turntable and bins, for weighing each bin, for compacting the refuse and for extricating the filled bins from the housing.

Abstract: A test tube handling assembly has an elongate member with an end for engaging a test tube and an end opposite thereto driven about an axis of the member for orbital movement with its axis. The member is a slender rod with a spherical bearing about a center part thereon between the ends thereof and along its axis. An arm extends from a support to carry the spherical bearing and permit limited motion of the rod relative to the support. A gripping means on the end for engaging the test tube holds the test tube and its contents during movement of the rod relative to the axis. A drive located on the support near the end opposite causes the test tube to swing about the center part. Contacting means with a seal for closing the open end of the test tube is part of an inflatable bladder which holds the open end of the test tube by fitting in the open end of the test tube. The drive has a motor for providing orbital motion.
