Abstract: A detachable bucket mixer for mixing viscous fluids and compositions while holding the bucket stationary during the mixing process includes a rotational drive and a clamping frame for mounting the rotational drive to a container. The clamping frame includes a barrel having a central axis, and two or more arms extending radially from the barrel. At the distal end of each of the arms is a flange having a claw-shaped grip configured to affix to a rim of the container. The arms may be capable of telescoping in order to accommodate varying diameters of buckets. Extending downward from the barrel is a drive shaft that may include a detachable mixing paddle configured for mixing viscous fluids. When the rotational drive is inserted into the barrel, it is connected to the detachable mixing paddle through the drive shaft to commence mixing. The clamping frame is configured to prevent rotation of the bucket relative to the rotational drive.

Abstract: In a drywall corner-trimming assembly, a splice is employed with two corner-trimming members, which approximate each other at one end of each member. Each member has a central portion and two flanged portions. With the splice straddling the members, a portion of one expansive surface of the splice faces the interior surface of the central portion of each member, which portion is located where the splice has at least one of the perforations. An adhesive layer is interposed between the same one of the expansive surfaces of the splice and the interior surfaces of the central portions of the members and is ventilated by the perforations.

Abstract: In a drywall corner-trimming assembly providing a "bullnose" configuration, two corner-trimming members and a splice are combined. Each member has a central portion and two flanged portions. The central portion has a generally arcuate profile. Each of the flanged portions extends from one of the lateral edges of the central portion at a step defining a lateral limit of a concave surface of the central portion. The members and the splice are assembled so that the splice straddles such members, so that a portion of one of the expansive surfaces of the splice faces the concave surface of the central portion of each of such members, so that the splice is concealed at least substantially by the central portions of such members are viewed, and so that each of the lateral edges of the elongate splice is pressed firmly against the step at one of the lateral edges of the central portion of each of said members. The splice is secured adhesively to the members, as by adhesive ribbons.
