Abstract: A refuse compactor includes a frame enclosing a compaction ram for compacting waste deposited into a container. A safety chute, having a magnet, is detachably mounted to the frame via pivots and notches. A magnet sensing switch wired into the compactor's control circuit interacts with the magnet on the safety chute to prevent operation of the refuse compactor when the safety chute is misaligned or absent. A ring bolt, collar, spring and washer are mounted within the frame. A plunger on a contact switch wired into the compactor's control circuit touches the washer. The contact switch interacts with the washer on the ring bolt to prevent operation of the refuse compactor when a predetermined amount of weight is placed on the safety chute. Deflection of the spring moves the washer toward the spring, breaking contact between the washer and plunger, opening the contact switch and immediately disabling the compactor.

Abstract: A condiment pump having a container and a lid. A cylinder extends downward into the container and contains a piston and a piston rod. A lower ball valve is located near the bottom of the cylinder, and a side arm tube extends from the lower ball valve to the top of the container. An upper ball valve is located at the top of the side arm tube, and a spout extends upward from the side arm tube. A washer plate covers the upper end of the side arm tube and has a eccentric hole and a post. The post extends downward from the washer plate to keep the ball of the upper ball at least a predetermined distance away from the hole. A pin engages one of eight notches in the rim of the washer plate. This allows the washer plate and the spout to be rotated through eight different positions.
