  • Publication number: 20130140170
    Abstract: A method of recovering an organic decomposition product from an organic source may include: a) causing an inert gas to flow through the reduction zone from a reduction inlet to a reduction outlet in such a way that pressure in the reduction zone is maintained above ambient pressure of a local environment for the material recovery system and b) applying electromagnetic wave energy to the organic source in the reduction zone via a bifurcated waveguide assembly in the substantial absence of oxygen to produce at least one gaseous organic decomposition product in the reduction zone that is exhausted from the reduction zone along with the inert gas through the reduction outlet. A material recovery system may include a housing with an inert gas inlet, a reduction zone, and a reduction outlet, an inert gas supply, an electromagnetic wave generator, a bifurcated waveguide assembly, and a controller.

  • Patent number: 6988866
    Abstract: A fork lift attachment for multi-purpose buckets that is easily installed and secured. The mechanism fits under the bucket and is supported by a slot on the top side of the tine and a latch at the heel of the tine. The latch is tightened causing the fork lift attachment to be cinched onto the bucket. A security chain readily and visibly secures the latch so as to prevent the fork lift attachments from being dislodged even if the hydraulics open the bucket.

  • Patent number: 6712618
    Abstract: A rotary connector assembly for an electrical apparatus on a rotating component is presented. The rotary connector assembly has a fixed base for mounting the assembly within the rotating component. The rotary connector assembly is rotatable relative to the rotating component. The attachment has an annular flange at the outer periphery and a mechanism that contacts the flange and supports the rotary connector portion. Connections at the base have terminations to attach incoming wiring and at the rotary portion to attach wiring to the electrical apparatus.
