A power unit is provided for providing power to rotate the packing head, via a driver, from a first position to a second position, the first position allowing trash to enter the container and the second position causing the trash to be compacted within the container. The frame holds the apex of the packing head above the container.

Abstract: First and second guide plates are engaged for linear sliding between them by a channel and rib engagement system. A grooving tool is carried by the plate associated with the rib, and the rib is in axial alignment with the tool head, such that the tool head can lead the rib. When a groove is being cut into a workpiece, the rib can follow the tool head into the cut groove to extend the range of the guide. Ribs of different size can be selected to coordinate with the tool and groove width. Filler strips similarly coordinate the channel width. An alternate or supplemental guide system joins the first plate to a series of accordion style hinged and foldable plates. These plates guide the first plate in linear movement as they fold or unfold.

A mechanism is also disclosed for facilitating setting the carriage and cutting head to a predetermined height over the base quickly and accurately.

Abstract: A clamp control system for a feller/buncher has three buttons for automating the operation of the harvesting and accumulating clamps. A CLOSE button, when momentarily actuated for the first tree of a bundle, closes the harvesting clamp and the accumulating clamp and then re-opens the harvesting clamp. When actuated again momentarily for the second and subsequent trees, the harvesting clamp closes, the accumulating clamp opens and re-closes and the harvesting clamp re-opens. Actuation of an OPEN button opens both clamps and resets the system to be ready for the first tree of the next bundle. Actuation of a STOP/CANCEL button freezes both clamps in their current positions.

Abstract: There is a method for the mechanical disintegration of biogenic sewage sludge, for which the sewage sludge, in an initial state, has microorganisms in the form of cells and a solid, which is formed essentially from aggregates of cells and suspended materials, and for which a disintegration process (3, 4) causes a destruction of aggregates and a destruction of cells. It is desirable to improve the disintegration. This is achieved in that, in a first disintegration step 3, primary destruction of aggregates and, in a subsequent, separate second disintegration step 4, primary destruction of cells is caused. Due to the use of two separate disintegration processes, an appreciable improvement in the disintegration is achieved, since fewer aggregates and more cells are supplied to the second disintegration process. The increased destruction of cells brings about the improvement in the disintegration.

Abstract: An apparatus for debarking logs comprising a drum rotatable about an axis and having an inner surface and outer surface with at least one movable debarking surface adjacent the inner surface of the drum to debark logs that come into contact with the movable debarking surface at a first rate. There is at least one fixed debarking surface at the inner surface of the drum to debark logs that come into contact with the fixed debarking surface at a second rate. The movable debarking surface is movable with respect to the inner surface of the drum between an operating position to allow contact between the movable debarking surface and the logs and a retracted position to minimize contact between the movable debarking surface and the logs.

Abstract: A method for providing an alternative periodic cover material for landfills by separating materials in a salvage operation. A non-sorted material stream including metallic and non-metallic components, which preferably includes automobile scrap, is fed to a shredder. After shredding, the non-sorted material stream is separated. The non-sorted material stream is first separated into two streams, namely, a heavy material stream and a light material stream. The heavy material stream is conveyed to a magnetic separator where ferrous metals are separated from non-ferrous materials. The light material stream is passed under a cross belt magnetic separator where the light ferrous metals are separated. The remaining light material stream is conveyed to a rotary trommel which separates the light material stream into two fractions based on size, with the fine material becoming relatively inert through processing and being used as a cover material for landfills.

Abstract: There is a method for which a sewage sludge is permitted to flow from a first connecting region 21 to a treatment device, which works with rotation and stresses the sewage sludge with severing parts, and from the treatment device to a second connecting region 1. It is desirable to improve the continuity to the operation and to attain a decisive increase in the disintegration. This is achieved by using a rapidly rotating pipe-head formation, which has a head 6 with radial openings 10 and radial wings 4, for the mechanical disintegration of biogenic sewage sludge. The edges of the openings exert a shear effect, while the wings exert an impact effect and the combination of these two actions, in conjunction with the rapid rotation, brings about the improvement in the disintegration.
