Abstract: Surface elements for the face of laser beam targets which more efficiently use the properties of light reflectance and absorption to aid a laser tool operator in accurately directing a laser's beam. The surface elements include beam alignment crosshairs and a background. A light-reflective material makes up or covers the background areas of the face not occupied by the beam alignment crosshairs, and allows the operator to better determine the direction and amount of lateral or vertical movement required for final alignment. The beam alignment crosshairs on the face of the target are formed from non-reflective, light-absorbing material that gives the beam an appearance of vanishing when precisely centered. Coupled with the light-reflective background, the light-absorbent crosshairs remedy multiple detriments from beam spread at greater distances, a weak beam, and a poorly discerned beam from bright or sunlit environments.

Abstract: An articulated chop saw mast section (30) replaces a rigid prior art mast section (22) between a chop saw base (20) and a chop saw swing arm assembly (23?). The articulation of mast section (30) provides a front-to-rear longitudinal movement of the swing arm assembly (23?) along an axis that is parallel to the longitudinal axis of a chop saw cutting wheel (26), ultimately providing front-to-rear movement of the cutting wheel (26) along its longitudinal axis. The movement of wheel (26) in this fashion provides a means for optimum adjustment to the geometric relationship between wheel (26) and the material to be cut. The ability of the articulated mast to achieve optimum cutting geometry offers greater cutting efficiency by reducing the point or points of contact between wheel (26) and the material's specific profile.

Abstract: Improved corners for overhead frames having primary and secondary fasteners that are located within the distal rectangular periphery of alpha oriented overhead frame components so that the width of bundled overhead frames is reduced; protrusions leading to snagging are eliminated; obstructions to the preferred, industry-wide, disassembled frame orientation are precluded; and frame components may be rigidly bundled into the alpha orientation without the wasteful and time-consuming use of temporary materials.

Abstract: A positioning and support tool for steel stud top track installations with which to temporarily support the top track in reasonable proximity to its final, installed position so that the track may be quickly and safely installed by one person. The tool uses magnets applied directly to the underside of corrugated steel sheeting or other overhead structural members. A hanger member is attached to the magnets and is capable of being placed beneath the top track to support the track at, or in close proximity to, its final, installed orientation. The tool is configured so that it remains fully effective and equally secure on irregular planes of corrugated steel sheeting while offering an uncompromised and quantifiable weight rating.

Abstract: An improved chop saw cutting deck is moveably attached to a chop saw base with a hinge mechanism. The axis of the hinge mechanism is perpendicular to the vertical axis of the chop saw's cutting wheel, thereby allowing a change to the angle of inclination between the cutting wheel and materials placed on the cutting deck. For certain material profiles, this alternate inclination angle presents a smaller material surface area to the cutting wheel, and translates to cooler, faster, and more efficient abrasive cutting action. The cutting deck is supported in its inclined position by a deck support means, and may be reconfigured back to a horizontal orientation for effective cutting of various other material profiles. In addition, the preferred location of the hinge axis provides a consistent, lateral line of elevation across the cutting deck, thereby assuring continuous contact of elongated materials with supplemental material supports, such as sawhorses, throughout the cutting deck's range of motion.

Abstract: A thin, flexible polymer tape (10) with longitudinally formed grooves (12) allows a section of tape (10) to be creased into a substantially rigid profile having multiple mounting flanges (16). Pressure-sensitive adhesive (14) on the mounting flanges (16) provides a means for fastening the tape (10) to an interior surface of a trash receptacle (17) in specific fashion, thereby creating an air channel. The air channel allows atmospheric pressure to equalize the potential vacuum beneath receptacle liners due to upward pull on liners when removing them from the receptacle. The equalization of potential vacuum results in less tearing and reduced effort in removal of the liners. The tape's flat profile (11) before creasing allows it to be configured into a tightly rolled form (18), thus increasing shipment options, facilitating a more compact shipment of product, and minimizing the air volume in product shipments.
