Abstract: An air blower including a flow-thru motor and fan unit encapsulated in resilient foam rubber layer within a substantially cylindrical plastic casing is provided which operates very quietly, delivers a sufficient quantity of warm pressurized air and filters the air which flows therethrough. The air blower is eloquently simple in design and relatively inexpensive to manufacture. The air blower incorporates a number of safety features including an outlet structure which prevents the introduction of water into the interior of the blower and a ground fault circuit interrupter. The air which flows through the blower is channeled through the motor to cool the motor and at the same time heat the air flowing through the blower. The resilient foam encapsulation separates the noise and vibration of the motor and fan unit from the casing. The casing includes a plurality of radial air inlets in its base and an air outlet in the side of the casing adjacent its upper end.

Abstract: There is disclosed a carpet seam finishing tool for smoothing and shaping the carpet at a seam joined with conventional hot glue carpet seaming tape comprising a pair of similar generally rectangular bodies hinged back-to-back having a width of at least about six inches and substantially greater than (four-inch wide) carpet seaming tape, the bottom smooth surface of each said body having longitudinal ridges on each lateral edge forming runners to guide the body along a carpet seam. The bottom surface of the body is preferably slightly convex across its width with air vent holes located to receive hot vapors or moisture from the hot carpet seam which is passes over. Each bottom surface further preferably includes an indentation on the end to allow the body to accommodate greater carpet height over tack strips near a wall.
