Abstract: An ejection blade for a compaction chamber with a hopper, the ejection blade including a blade body movable between a first position and a second position within the compaction chamber, and a lip attached to a lower portion of the blade body, the lip is movable to a raised position with respect to a floor of the compaction chamber when the blade body is moving to the first position and is in a lowered position with respect to the floor of the compaction chamber when the blade body is moving to the second position, wherein the first position is proximal to the hopper and the second position is distal to the hopper.

Abstract: A detection system for a side loading waste collection vehicle with a side lifting arm for lifting and lowering a bin and a gripping assembly near the end of the lifting arm, including one or more sensors to detect the presence of an object or person, control means to receive and process sensor input to control the operation of the lifting arm, wherein the detection system defines two zones where a first zone covers the space through which the bin moves between a raised and a lowered position and a second zone is the space surrounding the first zone; in use the movement of the lifting arm is stopped when a person or object is detected within the first zone and when a person or object is detected moving within the second zone.

Abstract: A slide-adjustable reclining double seat for boats and like applications comprising a support box and a pair of seats hinged back-to-back resting on the upper edges of the box sidewalls. A locking bar is cantilevered rearwardly beneath each seat bottom. A pair of opposed slides of molded plastic construction are affixed to the box sidewalls and have channels which slidably receive ends of the locking bars. Laterally aligned recesses in the channels define locking positions of the reclining seats.

Abstract: A hinge for a foldable boat ladder which permits the ladder to be stowed in its folded position without the need for additional fastening means. The hinge comprises a pair of sockets each having a plurality of leaves, the leaves interfitting. The leaves for the upper portion of the ladder have aligned holes carrying a stationary hinge pin. The leaves on the lower socket have inclined slots engaging this pin. In the lower hinge position the sockets are aligned. When the lower socket is swung upwardly 180.degree., its leaf slots slide downwardly and inwardly. The lower ends of these leaves engage the lower portion of the upper socket, and a bridge extending between the leaves above the pin engages a leaf on the upper socket. This prevents rattling and permits the sockets to be held firmly together, but still far enough apart so that steps on the upper and lower ladder portions may be aligned without touching.
