Abstract: A lever device includes an elongated body and a double-sided stretch releasing adhesive attached to the body, whereby the body can be firmly adhesively bonded to a surface and cleanly removed from the surface without damaging the surface by stretching the adhesive. The device may include a base, a body member pivotally connected with the base, and stretch releasing adhesive arranged to attach the base and/or body member to a surface or object. The base may be pivotally connected with an end of the body member or to the middle of the body member.
Abstract: A polymeric film having a plurality of perforations, which are specially structured and arranged is described. The polymeric film provides a strong, high-tensile strength material that permits hand tearing of the film along a desired tear path, providing a controlled tear propagation line. The polymeric film may also be incorporated into a multi-layer film having cloth-like properties of strength and tear propagation, and is suitable for use various adhesive tape applications. Methods of making the polymeric film are also disclosed.

Abstract: A hand-held, manually-operated sanding tool for use with a replaceable sheet-like abrasive material, such as sandpaper, includes a base member and one or more clamping mechanisms pivotally connected with opposed ends of the base member. The clamping mechanism(s) include a tensioning member arranged to slidably interface with a corresponding contact surface provided at the end of the base member to tighten the sheet-like abrasive material as it is installed on the tool. Further, the tensioning member positions a leading edge thereof so as to minimize possible harmful contact with a user's finger(s) during loading of the abrasive material.

Abstract: A method of detackifying an edge face of a roll of pressure sensitive adhesive tape, the method including contacting an edge face of the roll of tape with a non-free radically curable composition including water and film-forming agent, and drying the composition.
Abstract: A cast-in-place pass through firestop device for providing a passage in a partition in a structure through which wires, cables, pipes, and the like are run includes a housing having a riser portion with frangible connections that define removable bands that can be readily removed by a user to adjust the height of the device in accordance with the thickness of the partition into which the device is installed. The removable bands include pull tabs that provide grasping means to facilitate removal of the bands by a user along a frangible connection. The housing also includes a base portion including a recess with ribs for maintaining the firestop material in spaced relation from the base portion sidewall.
Abstract: A stretch releasing pressure sensitive adhesive tape includes a silicone pressure sensitive adhesive composition that exhibits a 180° peel strength on a glass substrate at 98% relative humidity of at least about 5.47 N/dm and a non-tacky tab. A stretch releasing pressure sensitive adhesive tape includes a pressure sensitive adhesive composition having a modulus at 1 radian/second and ?17° C. of no greater than about 1×107 Pa and a non-tacky tab.

Abstract: A wall repair compound useful for filling and repairing cracks, holes, and other imperfections in a wall surface includes a conventional filler material, a conventional binder material, and a dust reducing additive which reduces the quantity of airborne dust particles generated when sanding the hardened joint compound. Airborne dust reducing additives include oils, surfactants, solvents, waxes, and other petroleum derivatives. The additive can be added to conventional ready-mixed joint compounds and to setting type joint compounds. A method of reducing the quantity of airborne dust generated when sanding a fully hardened joint compound includes mixing a sufficient quantity of the dust reducing additive with the joint compound prior to when the joint compound has been applied to the wall.
Abstract: An adhesively mounted angled clamp-like device for producing a compressive force or tensile force includes a frame, at least two plungers arranged at an angle movably connected with the frame, and double-sided stretch releasing adhesive attached to at least one of the frame and the plungers. The frame and/or plungers can be firmly adhesively bonded to a surface or object and later cleanly removed from the frame, plungers, and/or surface without damaging the surface and without leaving adhesive residue by stretching the adhesive.
