  • Patent number: 6067888
    Abstract: A carbide-tipped circular saw blade is formed by brazing cutting tips of tungsten carbide to the teeth of a steel blade blank, thereby creating discoloration on the planar surfaces of the blade adjacent the rim. Substantially the entire surface of the blade is sandblasted with blast media to remove the discoloration while generating a substantially uniform coloration and texture to the planar surfaces of the blade. User-readable graphics are overprinted upon the blasted surface. The graphics and the surface appearance of the blasted area are selected to be at a predetermined contrast, and the carbide cutting tips retain a visual appearance different from the rest of the blade, such that the graphics and cutting tips are visually perceptible to a potential purchaser at the blade's point of sale. The saw blade surfaces are sandblasted by jets directed at both sides of the saw blade. The blast nozzles are oriented such that the vertical components of force of the jets offset one another.

  • Patent number: 6067916
    Abstract: In a process for gasifying and burning waste materials, the waste materials are introduced into an incinerator (1) and end up on a burning grate (6) to which combustion air is conducted through various undergrate forced draft chambers (8a to 8e). In the first area combustion air is introduced at a superstoichiometric level in order to ignite the waste materials. Then, via the undergrate forced draft chambers (8c to 8e), oxygen is mixed into the air which is used for the gasification, thereby establishing a substoichiometric level which results in gasification of the waste materials. The combustible gases which result from this process pass via a waste gas flue (12) into a second furnace (2), in which the gases are burned at a superstoichiometric level through the introduction of combustion air. The resulting waste gases pass to a heat exchanger (3).

  • Patent number: 6067923
    Abstract: A hull configuration for the planar surface region in the tunnel area between hulls(pontoons) in a fishing type catamaran. In the tunnel bottom surface is a raised frontwardly located center section adjacent the bow forms a venturi where low pressure is formed by incoming waves passing about the squared off rear portion of the center section. Behind the center section is a raised longitudinal stabilizer running to the rear(stern) of the boat which diverts and splits incoming air coming from the bow section to each side of the tunnel. Adjacent to the center section are two raised side stabilizers which straighten out incoming air and reduce the turbulence effects therefrom. On the rear ends of the two side stabilizers and the center section are through-holes that allow for venting excessive pressure from inside the tunnel to the interior of the bilge of the boat.
