摘要:
A bracket assembly system is provided to hold side and center channel speakers. The assembly system may be positioned on a base support structure such as a television or cabinet. In a typical arrangement, left and right satellite speakers are positioned such that the center of gravity is approximately aligned with the pivot axis of the side arms. In addition, additional speakers may be positioned along the support arms and the speakers may be rotated adjusting to desired speaker angles to accommodate for various room acoustics.
摘要:
A process for forming flexible noise attenuating cutting line for use in rotary vegetation trimmers formed of at least two monofilament polymer strands bonded together in a twisted disposition or a single strand twisted about its central axis in which the strand or strands are extruded in a molten disposition through a single die that is rotated during the extruding step either to twist the two strands together about a central longitudinal axis or a single strand about its own longitudinal axis such that upon cooling, stretching and heating, a flexible noise attenuating line is created in a continuous online process.
摘要:
An assembly for use in continuously forming a plurality of lengths of flexible noise attenuating cutting line for use in rotary vegetation trimmers. The assembly includes a breaker plate having a conically shaped inner portion and a planar outer portion. A plurality of extrusion dies are disposed in the outer portion wherein each die defines a die hold configuration at its lower end for the extrusion of one or more monofilament polymer strands therethrough, and a drive assembly is provided for rotating each of the dies at a predetermined speed such that upon directing a flow of molten monofilament polymer material onto the breaker plate, the material is directed from the inclined central portion onto the planar outer portion where it is extruded through the rotating dies to create a plurality of twisted strands of polymer material that upon cooling, stretching and heating, define lengths of flexible noise attenuating cutting line.
摘要:
A golf putting stroke trainer including an inertial sensor. The sensor is responsive to axial rotation and push-pull movement of the club face. The sensor is disposed in electrical communication with an alarm circuit. The trainer is positioned within a standard grip on the shaft of a putting club and provides a user-detectable signal if, during a putting stroke, the putter is rotated around the longitudinal axis of the shaft of the putter or moves in a direction parallel to the plane of the club face.

摘要:
A clamp is provided suitable for clamping an object to a balustrade or other analogous structure. The clamp is attached by clamping the slats or spindles in the balustrade between a clamping nut and an adjustable jam plate. When the clamping nut is disengaged from the clamp, the jam plate may be slide along a shaft to position the jam plate. When the clamping nut is engaged with the clamp, the jam plate is locked in place on the shaft.
