Abstract: A container assembly can have a plurality of sides. Two or more of the sides has one or more grooves. An insert can be installed into one or more of the grooves. Clips can be used to connect groove(s) and/or insert(s) on one side of the container assembly to groove(s) and/or insert(s) on another side of the container assembly.

Abstract: A building system can comprise wall, floor, and/or ceiling panels. A first profile with two cavities extending along different sides of the profile can be used to connect similar panels together. A second profile can be used to connect dissimilar panels. A plurality of fastening clips can be used to lockingly engage a wall panel at one end and one of either a wall panel, a floor panel, or a ceiling panel at the other end. The building system can be configured to not require other fasteners besides the clips and profiles to hold the panels together.

Abstract: A modular enclosure system comprising a plurality of detachably interconnected wall panels, each comprising a rectangular frame that includes upper and lower transverse beams and spaced apart side-forming elements attached to the upper and lower transverse beams where each of the side-forming elements comprise a coupling device for detachably interconnecting the frame to a similar side-forming element of an adjacent wall panel frame with at least one locking spline in sliding engagement with each inter panel coupling in the system for securing adjacent wall panels together.

Abstract: An animal feeder comprising a feed serving trough having frontal animal access and a feed delivery chute with an openable trough door, a plurality of feed storage modules stacked on the trough and over the trough door, the feed modules having an openable top comprising double trap doors, a latch for maintaining the trough door and each respective one of the traps doors closed and a linear actuator operatively connected to each of the latches for causing the latches to release the trough door and the trap doors of the respective feed boxes in a timed sequence.

Abstract: A connector assembly for releasably interconnecting a plurality of elongated hollow bodies at an angle to each other, comprising a rigid connector element having a central base portion and a plurality of mutually angular legs extending from the base portion, a plurality of partitions or partial partitions carded by the base portion, each partition having an opening for receiving a shank type of fastener and further including at least one elongated hollow body, a boss integral with and disposed within the interior of the hollow body for receiving the shank of a fastener which is received in the opening in the partition.

Abstract: A fastening system for making right angle interconnections between first and second rigid structural components of a framework, each having at least two flat mutually parallel sides and each carrying a track. A "U"-shaped connector having a flat base and mutually parallel upright stems is disposed so that the base of the connector engages one of the tracks of the first frame member and the upright stems engage the respective tracks of the second frame member.
