Abstract: A filtration system to filter air from a waste vessel includes: a fan assembly having a fan and an air flow channel in fluid communication with the waste vessel to draw air from the waste vessel; a housing interposing the waste vessel and the fan assembly, the housing having a filter receptacle to receive a filter unit therein, the received filter unit being in fluid communication with the air flow channel wherein the fan assembly draws air through the filter unit to exhaust the air out of the air flow channel; an activator to activate the fan assembly; and, a decimator for killing or eliminating particulate matter in the air flow.

Abstract: A filtration system for a toilet including a fan assembly having an air flow channel in fluid communication with a toilet bowl, a housing interposing the toilet bowl and the fan assembly to receive a filter unit therein such that the filter unit is in fluid communication with the air flow channel. A controller can selectively activate the fan assembly in response to various signals.

Abstract: A dirt and rock cutting tool includes a cutting bit mounted on a bit holder. The cutting tool is secured to a bit holder in a manner that allows infinite rotational positioning of the cutting bit but substantially prevents rotation of the cutting bit once secured to a bit holder. The bit holder includes a planar shoulder and a shank extending from the planar shoulder. Shank has a terminal end which includes a threaded bore member. The bit holder includes a receiver dimensioned for receiving the shank. At least one hardened pin member is carried by the bit holder. At least a portion of the tip of the hardened pin extends beyond the surface of the shoulder. Upon securing the bit holder to the bit block, the hardened pin is pulled into the softer metal of the bit block, substantially preventing rotation of the bit holder within the bit block.

Abstract: A cutting tool for use on earth working and land clearing equipment includes a working body portion having a continuous slot formed transversely therethrough in open communication with the first end and an exterior surface thereof. A cutting insert having a V-shaped notch formed in the front cutting end thereof is positioned and rigidly secured within the slot. A mounting shank extends outwardly from and is attached to the second end of the working body portion for enabling attachment of the cutting tool to a tool holder used on such earth working and land clearing equipment.

Abstract: A cutting tool for use on earth working and land clearing equipment includes a working body portion having a cavity disposed therein which begins at a peripheral edge of a first end and extends inwardly towards a second end of such working body portion. The cavity is provided with a cutting portion disposed at an acute angle about such peripheral edge. A mounting shank extends outwardly from and is attached to the second end of the working body portion for enabling attachment of the cutting tool to a tool holder used on such earth working and land clearing equipment. At least one pin member engaging the complimentarily aligned grooves within an aperture of the tool holder and an outer surface of the shank portion is used to securely retain the cutting tool within the tool holder.

Abstract: A bit block for use in excavation and mining. The bit block is adapted to receive a bit and to be welded to equipment utilized for boring, drilling, trenching and mining. The bit block is designed to secure and protect the bit while it is penetrating rock and hardened earth material. The bit block defines a shroud adapted to receive and protect the distal end of the bit. The bit block defines an enlarged welding surface to enhance the integrity of the weld. The bit block defines a plow on its leading end to assist in removing excavated material.
