  • Patent number: 4382471
    Abstract: A low damage beet cleaner and elevator for a beet harvester is described. Beets are lifted elevationally between a lugged, endless elevator draper and an endless, upwardly inclined belt having flexible, finger-like projections. The draper and the belt are driven through their respective circuits with the belt being driven at a speed faster than that of the draper. The speed differential between the belt and the draper causes the finger-like projections to flexibly engage with the beets producing a brushing effect on the beets to clean them while they are being elevated for loading.

  • Patent number: 4244306
    Abstract: A planter for seed crops, such as grains. A wheeled framework supports the apparatus for movement about a field. At the front of the framework is a row of transversely spaced chisels which produce tilled areas parallel to the path of movement of the framework and separated from one another by strips of untilled soil. Each chisel carries a roller that breaks up any resulting clods of soil. Liquid fertilizer is directed to the tilled areas by delivery conduits extending along the rear of each chisel to their respective lower ends. The rollers provide a cover of soil to the liquid fertilizer. A drill apparatus is mounted to the framework behind the chisels, with individual openers in longitudinal alignment with the respective chisels for planting seeds in the tilled soil at an elevation above the elevation at which fertilizer has been supplied and without the strips of untilled soil.

  • Patent number: 4066206
    Abstract: An improved continuous envelope assembly including an elongated ply of paper having control punch margins along longitudinal edges thereof, individual envelopes in the assembly being delimited by transverse lines of weakening extending across the assembly, die cuts in the ply adjacent both longitudinal edges thereof and adjoining the lines of weakening at one side thereof to define the corners of envelope flaps, first glue lines on the ply adjacent the lines of weakening and on the sides thereof opposite the die cut, individual sheets having widths less than the ply and lengths less than the distance between the lines of weakening secured to the ply by the first glue lines, the ply longitudinal edges being folded over the longitudinal edges of the individual sheets, second glue lines securing the ply longitudinal edges to the sheet longitudinal edges, the control punch margins being reverse folded away from the sheets to extend to the sides of the respective sheets longitudinal edges.
