Abstract: A vibratory percussion rammer includes a gear box, a percussion delivery unit extending downwardly from the gear box, and one or more slide bearings disposed in the percussion delivery unit between adjacent surfaces of reciprocating metal components. The slide bearings are made from a sheet of plastic material that is curved into the shape of a tube having a C-shape in cross section and define an open seam extending the entire length of the slide bearing. Slide bearings according to this design can be disposed in the percussion delivery unit to eliminate some or all of the metal-on-metal contact between reciprocating components, including between the ram and shaft assembly and spring box and the guide cylinder, the spring separator and the spring box, and the shaft of a ram and shaft assembly and an upper end of the spring box. The seam width of any slide bearing is wider than the anticipated width-wise thermal expansion of the slide bearing during normal operation.

Abstract: The invention relates to a device for stripping leaves from heading plants grown in rows. The device, which is movable in a direction of movement, comprises at least two rotary shafts, on which leaf strippers extending substantially transversely to the shafts are provided. The shafts extend substantially in the direction of movement of the device, such that leaves that grow under a head are removable from a stalk of a plant, in particular broccoli and cauliflower, between the shafts by the leaf strippers. The shafts, which lie in a virtual plane, include an angle between each other, such that front ends of the shafts are spaced further apart than rear ends of the shafts. The leaf strippers are finger-like projections, and the finger-like projections located near the front ends of the shafts are longer than the finger-like projections located near the rear ends of the shafts.

Abstract: A dock leveler with a pivotal deck includes a stop mechanism that provides the deck with a positive stop at the deck's vertically stored position without the deck's actuator having to be fully extended. With the actuator being less than fully extended, the stop mechanism and actuator can exert opposing forces that help prevent the deck from rocking back and forth as the deck settles to its stationary, upright position. In some cases, the stop mechanism is part of a combination stop-and-lock mechanism that includes a locking device for temporary providing a redundant or alternate lock that prevents the deck from descending unexpectedly while the dock leveler is being serviced or repaired.

Abstract: Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.

Abstract: A baffle arrangement is provided for a harvested crop recovery machine such as a baler. The baffle arrangement has two baffles that follow each other in the direction of the flow of the crop. The upstream baffle is configured in the form of a rake and permits harvested crop lying upon it to fall back into the flow of the crop. A second baffle following the above baffle is configured as a deflector plate having a substantially closed surface and extends above an overshot conveyor in order to conduct harvested crop lifted by it with a minimal amount of friction and prevents the harvested crop from leaving the flow of crop.

Abstract: A pavement milling sled upholds a rotating pavement milling drum during travel over pavement preselected for milling. Coplanar lower faces of laterally-separated left and right runners configured for sliding travel on the surface of the pavement define a sled floor. A milling frame mounted between the runners circumscribes a milling region, wherein rotation of the milling drum dislodges pavement located in the path the sled below the sled floor, pulverizes dislodged pavement, and deposits pulverized pavement to the rear of the sled. Left and right milling region sidewalls extend upwardly from the sled floor on opposite sides of the milling region. A guard plate is secured between the milling region sidewalls forward of the milling region at a distance above the sled floor. A discharge baffle extends between the milling region sidewalls at the back of the milling region in close proximity to the sled floor.
