  • Patent number: 6174472
    Abstract: The instant process forms a pellet comprised of at least sixty percent composted sewer sludge, up to forty percent cellulosic plant material and up to fifteen percent nutrient materials and chemicals for soil enhancement and plant nutrition that provides a combination of both long and short term beneficiation of soil and herbage and has no pathogenic microbes above regulatory ranges. The composted sewer sludge comprises primary sewer sludge admixed with cellulosic plant material that is thermally treated at temperatures between 140 and 180 degrees F. during composting to destroy mesophyllic pathogenic microbes and the viability of reproducible botanicals including seeds, but leave most thermophilic soil enhancing microbes in a viable state. Additional fibrous cellulosic material and chemicals are admixed with the composted sewer sludge and the mixture pelletized in a thermal process that raises pellet temperature to between 140 to 180 degrees F.

  • Patent number: 4850405
    Abstract: A wheeled trailer provides carriage for a delimbing member having associated means to move a log therethrough and a cutoff member to cut delimbed logs to merchandizable lengths. The vehicle is propelled by a separate tractor and logs are presented to and removed from the mechanism by separate log handling devices. The vehicle is of small simple, rugged, durable nature to accommodate Western logging on rough and rugged terrain. The delimbing and cutoff members are pivotally mounted on the vehicle, and pivotally interconnected to each other to require parallel orientation so that delimbed logs are cut to length substantially perpendicularly to their axis. Log cutting is accomplished by a chain-type saw.
