Abstract: This invention is directed to a stirring apparatus comprising: a plurality of blades having between a 5° to 180° twist along the length of their axis attached perpendicularly to a shaft so that a downward fluid flow is created when the shaft is rotated by a rotary drive; and, a plurality of standards attached to the plurality of blades separating the plurality of blades and arranged parallel to the shaft and rotated between 0° and 25° relative to a plane defined by the blades and the standards so that an inward fluid flow is created when the shaft is rotated and a bottom blade connected to the standards.

Abstract: This invention is directed to a grout removal tool comprising: a frame having a proximal end and a distal end; a blade removably attached to the distal end of the frame; a wheel rotatably attached to the proximal end of the frame for supporting the frame above a surface; a pressure pad rotatably attached to the frame having a pressure pad cavity defined in the pressure pad for receiving a portion of the frame; a hinge pin disposed inside the pressure pad cavity; a hinge pin opening defined in the rearward portion of the frame for receiving the hinge pin allowing the pressure pad to rotate from a open position to a closed position; and, a detent assembly having a first member carried by the pressure pad and a second member carried by the frame juxtaposed when the pressure pad is in a closed position.

Abstract: A handle assembly having a handle and a carrier arm. A receiving channel included in the carrier arm. A plurality of flange openings in the receiving channel being wider and extending deeper into the carrier arm than the receiving channel. A flange slot included in the carrier arm adjacent each of the flange openings and recessed from the receiving channel. An attachment unit having an attachment rail including a base rail running along a portion of a top side of the attachment unit. A plurality of securing flanges positioned on the base rail that project laterally outward and above the base rail. The securing flanges being received into the flange openings and the base rail being received into the receiving channel so that a sliding movement of the carrier arm along the attachment rail directs the securing flanges into and out of the flange slots.

Abstract: A sponge having the following components by percentage of total weight of the sponge: polyoxyalkycene polyolo between about 15% to 45%; tolvene diisocyanate between about 5% to 25%; a flame retardant less than 10%; water less than 10%; polypropylene glycol between about 8% to 19%; slow rebound polyether between about 10% to 20% and silicone oil less than about 2% and wherein said sponge has a volume about 3.5 times less than expanded when compressed in a vacuum sealed package.
