Abstract: A self-drilling anchor assembly including a drill bit and an anchor positioned over and attached to the drill bit. In various embodiments, the drill bit includes a shank, a drill head integrally connected to one end of the shank, and a threaded tail integrally connected to an opposite end of the shank. The tail includes a mechanical engaging structure that is engageable by a tool to rotate the drill bit, and a helical thread formation to facilitate attachment of a securing device such as nut and washer to the tail of the drill bit. The anchor includes an elongated generally tubular body including an inner surface defining a longitudinally extending inner channel, and a head integrally connected to and extending from a first end of the body. The drill bit is configured to remain in the anchor and in the substrate after installation of the anchor assembly in the substrate.

Abstract: An anchor assembly including a threaded anchor and a threaded drive pin positionable in the threaded anchor, a method of using or installing the anchor assembly to attach a fixture to a substrate, and a method of removing or un-installing the anchor assembly from the fixture and the substrate to detach the fixture from the substrate.

Abstract: A measuring device that includes in various embodiments a self supporting object attacher and an electronic measuring system supported by the self supporting object attacher. The electronic measuring system is configured to determine or enable the determination of a distance of a space between a first object on which the object attacher is positioned and a second object spaced apart from the first object.

Abstract: A golf club head is presented, the golf club head having a top surface, a front surface, a back surface, a first side surface, a second side surface and a bottom surface. The top surface has a matte green finish, an alignment mark, and an opening for mating with a shaft, wherein the matte green finish reduces distraction of a user during a golf swing.

Abstract: A new and improved fastener wherein the tip portion includes a unique and novel structure that enables and facilitates the insertion of the fastener into both wood and concrete substrates. The tip portion includes a half-cone structure in which a pointed tip is defined between a radially outer conical surface portion and a radially inner flat or planar surface portion.

Abstract: A new and improved fastener for fastening together thin gauge sheet metal components comprises a forwardly extending pointed tip portion having a tangent ogive configuration so as to facilitate the fast and accurate penetration of the fastener into and through the thin gauge sheet metal components without causing any excessive enlargement of the apertures formed therein, and a shank portion which comprises a lower, spiral thread shank portion which continues to facilitate the ease of penetration of the fastener into and through the thin gauge sheet metal components, and at the same time causes a mating thread to effectively be extruded within the thin gauge sheet metal components so as to effectively develop or generate enhanced surface areas or regions for ultimate contact with an upper shank portion of the fastener when the fastener is fully driven and seated within the thin gauge sheet metal components.

Abstract: A new and improved fastener, uniquely adapted for securing together vertically oriented stud members and horizontally oriented track members of wall framework structures, comprises a forwardly extending pointed tip portion having a tangent ogive configuration so as to facilitate fast and accurate penetration into and through thin gauge sheet metal members without causing any excessive enlargement of the apertures formed within the thin gauge sheet metal member, and a shank portion which comprises a lower, spiral-threaded shank portion which facilitates the ease of penetration of the fastener into and through the thin gauge sheet metal members, and which causes a mating thread to effectively be extruded within the thin gauge sheet metal members.

Abstract: Sputtering apparatus and method employing an auxiliary magnetic structure situated between the substrate holder and target of a plasma sputtering chamber to control-the lateral extent of the plasma. The auxiliary magnetic structure, possessing a lower field strength in the plasma region than the principal magnet or magnets, is situated immediately outside of and around a circumference of the chamber's anode shield. The principal magnets maintain the plasma in a ring adjacent to the sputtering target. The auxiliary magnetic structure causes the plasma ring to expand toward the edge of the target or contract away from the edge depending on the magnetic strength and polarity of the structure and its position relative to the target.
