Abstract: A filtration housing unit for use with a ventilated toilet seat. The filtration housing unit is designed for filtering air evacuated from a toilet using the ventilated toilet seat. The housing is configured to be mounted on a wall behind a toilet and under the toilet tank such that it is substantially concealed from view. At least one evacuation hose is attached to the underneath of the housing and extends to the ventilated toilet seat to establish fluid communication from the interior of the toilet bowl to the interior of the housing. The housing is provided for enclosing the components of a fan assembly for drawing the noxious odors from within the toilet bowl. At least one hose receptacle is provided for receiving the proximal end of at least one hose. Each hose is provided with an enlarged radius at the proximal end thereof, and is fabricated from a flexible material such as plastic. An air filter is carried within the housing to condition air.

Abstract: A rotatable cutting tool for earth displacement equipment for maximizing penetration into hard rock during mining, trenching, drilling, or boring operations. The bit penetrator pocket protector for earth displacement equipment includes a body which defines an upper bit end and a lower shank end. The upper bit end defines a bit insert opening configured to detachably accept a penetrator bit tip. The lower shank end is configured to be securable to a penetrator holder that is welded to an implement of earth working equipment such as the chain excavator or a rotatable drum, or the like. A flange, or pocket protector, is defined between the upper and lower ends in order to provide protection for the bit penetrator lower end and a holder in which it is received by minimizing rock and earth fines from contacting and building up between the holder and bit penetrator.

Abstract: A ventilated toilet seat assembly for evacuating noxious odors from within a toilet bowl. The ventilated toilet seat defines an external channel on the lower surface thereof between a pair of concentric risers, including an innermost riser and an outermost riser, each being configured to form a seal along the surface of the toilet bowl when the ventilated toilet seat is lowered into engagement therewith. The external channel is configured to open within the toilet bowl to establish fluid communication from within the toilet bowl to the external channel. An outlet is defined between the external channel and a hinge assembly, which includes a hinge post for mounting the ventilated toilet seat to a conventional toilet. The hinge post defines an internal conduit for evacuating the air within the toilet to an external location. The ventilated toilet seat may include a toilet seat upper and a riser plate secured thereto and which defines the concentric risers on the bottom surface thereof.

The ventilated toilet seat defines an external channel on the lower surface thereof between a pair of concentric risers, including an innermost riser and an outermost riser, each being configured to form a seal along the surface of the toilet bowl when the ventilated toilet seat is lowered into engagement therewith. The innermost riser defines a plurality of openings to provide for fluid communication from within the toilet bowl to the channel. An outlet is defined between the external channel and a hinge assembly, which includes a hinge post for mounting the ventilated toilet seat to a conventional toilet. The hinge post defines an internal conduit for evacuating the air within the toilet to an external location.

Abstract: A tooth attachment for earth working equipment which is configured to receive a conventional cutter bit. The tooth attachment includes a body which defines an upper end and a lower end. The upper end defines a bit holder configured to receive a conventional cutter bit and the lower end is configured to be releasably securable to the post of an implement of earth working equipment such as dragline equipment, a backhoe, a bulldozer, a grader or the like.

Abstract: A drill bit is provided which has a novel blade having an elongate longitudinal protrusion positioned axially along the centerline of one side of the blade. The body is adapted to retain the blade in a transverse slot on one end of the body. The slot is provided with a centrally located longitudinal recess along one of the sides of the slot which is adapted to receive the longitudinal protrusion of the blade when the blade is positioned in the slot.

Abstract: A miner bit has a base portion formed of two different metallic members welded together, one being adapted to be mounted to a continuous mining machine and the other having a frustoconical end portion welded to a frustoconical tungsten carbide bit.
