  • Patent number: 5673861
    Abstract: An apparatus for converting unconsolidated medical waste into medical waste residue. A horizontal shaft supports revolving cutter blades having teeth which intermesh with teeth on stationary cutter blades. The rotating shaft forces the medical waste into contact with the cutting region between the revolving and stationary teeth to generate medical waste residue, and blades transport the medical waste residue toward a discharge. A first stage cutter can make an initial cut on the unconsolidated medical waste, and a second stage cutter can further reduce the particle size of the medical waste residue. A disinfectant or sterilant can be introduced into contact with the medical waste to convert infectious waste into nonhazardous medical waste residue.

  • Patent number: 4605175
    Abstract: A coffee grinder grinds a predetermined amount of roasted coffee beans based upon the weight of the beans. The beans fall from a hopper into a grinding head which grinds the beans in a two-stage process. The first stage includes a cracking cutter, consisting of a cone cutter and a reel cutter, which reduces the beans to an initial particle size of approximately 1/16 of an inch in cross-section. The particles are then progressed by the grinding head, for the second stage of fine grinding, to an adjustable micro grinder consisting of two opposing rings having micro teeth on their inwardly facing surfaces. The cutters and grinder rings are mounted on thermally conductive metal hubs and a fan draws air around and behind the cutting teeth to cool them and avoid heating the coffee particles during the grinding process.

  • Patent number: 4113189
    Abstract: A pressurized roller-colloid mill in which the conventional rotor and stator of a colloid mill are preceded by one or more adjustable-thrust roller bearing assemblies disposed in a series relationship. A product to be refined in the form of a slurry is pumped into the feeding port of the mill to pass between the rollers and the inner and outer raceways of one or more roller bearing assemblies, then to the gap between conventional rotor and stator elements of a colloid mill. The multiple rollers and their cooperating raceways constitute working surface areas far in excess of conventional colloid mill rotors and stators. Gang mounting of the rotor of the mill and the inner raceways of the roller bearing assemblies upon a common axially movable shaft permits gap adjustment for the enhancement of milling action. A relief valve at the outlet of the mill cooperates with the adjustable gap to provide an output of product of any desired particle size down to the low micron range.

    Abstract: A vacuum blower-type mobile unit for shredding leaves and other garden debris. The unit comprises a pair of coaxially disposed rotors operated at respectively different speeds, the blades of the two rotors being separated by a minimum practical axial clearance to provide shredding action. Shredding is further enhanced by stationary radial blades fixed to the casing adjacent the input to the slow speed rotor, and a circular plate formed to include a large number of exit guide vanes including fixed blades disposed adjacent the output from the high speed rotor. The speed differential between the rotors and the shapes of the blades cooperate to create between them a high velocity axial stream of air and debris which moves smoothly through the machine, depositing the product in comminuted form in a bag or other container.
