  • Patent number: 4144918
    Abstract: A mobile tree harvester includes a shear mounted at the base of a harvesting frame for shearing a tree trunk, a grip arm pivotably mounted to the frame above the shear for gripping the tree trunk, delimbers mounted above the grip arms for removing branches from the trunk, and an endless tract mounted on each grip arm for propelling the tree trunk along the forward frame. Lift arms pivotably couple the forward frame to a main body of a wheeled vehicle. A sway mechanism is coupled to both lift arms to provide for relative movement of one lift arm with respect to the other such that the harvesting frame can sway from the vertical position in a left or right direction. A tilt mechanism is coupled to the harvesting frame, lift arm, and main body to maintain the frame in its vertical ground position as the lift arms lift the frame off the ground. The tilt mechanism also tilts the frame about an axis transverse to the vehicle axis to a horizontal position such that the sheared end of the tree trunk faces rearwardly.

  • Patent number: 4122687
    Abstract: A refrigeration system for a refrigeration unit having an evaporator coil through which cooling fluid is circulated. Air is forced across the evaporator coil and valve means directs the flow of air into an enclosed freezer compartment or alternately to a warmer enclosed refrigerated compartment which has a temperature above 0.degree. C. The air normally passes into the freezer compartment until the evaporator coil reaches a predetermined low temperature, below 0.degree. C., then the flow of cooling fluid through the coils is stopped and the valve means directs the air flow to the refrigerated compartment to defrost the evaporator coil. When the evaporator coil reaches a predetermined high temperature above 0.degree. C., the temperature cooling fluid will once again be circulated through the evaporator coils and the valve means will again direct the air flow through the freezer compartment.

  • Patent number: 4120311
    Abstract: Vacuum operated debris removal apparatus for a power broom comprises an enclosed hopper for collecting debris swept up by the power broom and vacuum removal apparatus for continuously removing the debris from the hopper and conveying the debris away from the apparatus. The hopper has an outlet in the bottom thereof and inclined sides leading to the outlet, so that debris collected in the hopper is urged by gravity toward the outlet. A vacuum manifold is attached to the outlet for applying a vacuum to the outlet. The hopper is independently supported on wheels and attached to the power broom such that the debris removal apparatus can be moved over the surface being cleaned along with the power broom without having the weight of the debris removal apparatus being carried by the brush of the power broom. This support mechanism is adjustable to vary the height of the hopper with respect to the power broom.

  • Patent number: 4118167
    Abstract: A multiple-cavity extrusion die for coextruding a plurality of indefinite lengths of multiple-layer tubular rubbery material. Core mandrels which extend into openings in the face of the die are adjustable for concentricity with respect to the die by internal or special external adjusting means. Cylindrically shaped core dies have frustro conically shaped forward portions which form extrusion dies with the cores for the core layer of rubbery material and form extrusion dies with a beveled back edge of an adjustable cylindrical cover die. Each of the cover dies is axially adjustable with respect to a respective core die to adjust the speed at which the individual tubes are extruded so that the speed of all tubes can be equalized. Special concentricity plates on the face of the covered dies are adjustably mounted with respect thereto so as to adjust the die openings for concentricity of the cover layer of rubbery material of each tube.

  • Patent number: 4116210
    Abstract: A diverter spout assembly includes a spout having a discharge opening, an inlet and a passageway therebetween. A valve mount is secured at a rear portion adjacent the inlet. The valve mount has a cavity therein which defines an inner chamber having a passage therethrough to the discharge opening. A diverter conduit is operably connected to the inner chamber. The diverter conduit is substantially transverse to the passage through the inner chamber. A jet nozzle is mounted within the inner chamber substantially aligned with the passage. The jet nozzle has a front open end aligned over the front surface of the diverter outlet to minimize water leakage and siphon effects through the diverter outlet when water passes through the discharge opening. A valve is operably mounted on the valve mount to close the inner chamber from the discharge opening so that water supplied from the inlet opening is diverted to the diverter conduit.

  • Patent number: 4111564
    Abstract: A reference plane producing method and system wherein a substantially collimated beam of electromagnetic radiation, for example, a laser beam, is reflected to simultaneously disperse the beam in different directions to form a thin plane of such radiation which can be used, for example, as a construction reference line. In a preferred embodiment a primary cone having its apex projecting towards the incident beam and its optical axis coaxial with the incident beam is used to reflect the beam of light. Various embodiments of a basic apparatus having integral or separate collimating and leveling devices are described. The preferred source of radiant energy is a laser, most preferably a second-mode laser having a donut or annular shaped beam and is projected against an axially aligned conical reflecting surface. The conical surface can be a female cone formed by axially drilling into a transparent transmission tube, such as the emission end of a fiber-optic transmission system.
