  • Patent number: 4334471
    Abstract: A printing system is disclosed which permits the printing of indicia on a continuously moving web at a fixed position offset from previously printed, evenly spaced web marks. The fixed position of the printed indicia relative to the web marks is independent of the velocity of the web. A web mark sensor, which may be part of the system to which the present invention is retrofitted, detects the passage of each previously printed web mark past a detection position. A registration circuit controls the timing of the printing of the indicia on the moving web and provides START signals for a servomotor-driven rotary print head which includes one or more peripherally mounted printing elements. A tachometer is mechanically coupled to a web transport mechanism to produce an output voltage which provides the velocity command for the servomotor drive of the rotary print head to match the rotational velocity of the print head to the linear velocity of the web during the printing interval.

  • Patent number: 4334484
    Abstract: The present invention is directed to a biomass gasifier combustor which operates by gasification and combustion of the biomass to produce a clean effluent gas which can be used directly for grain drying or other applications where thermal energy is required. This biomass gasifier combustor burns crop residue clean enough so that the combustion gases can be used directly for grain drying without the need for a heat exchanger to isolate the combustion gases from the drying air. The biomass gasifier combustor includes a screw feeder tube having a screw feeder disposed therein. The screw feeder forces the biomass into a first combustion chamber. Primary combustion of the biomass produces a first combustion gas. A venturi gas pump creates a negative pressure region in the gasifier, drawing the first combustion gas into a second combustion chamber.
