Abstract: The toothbrush includes a handle portion and a brushhead assembly which comprises a head portion and a stem portion. The head portion includes a bellows-like acoustic action member for creating acoustic wave action as it moves in and out in response to an acoustic driving force. A drive system is located in the handle and includes an audio speaker-type assembly to create acoustic waves which are transmitted through a transmission line to the acoustic action member. The acoustic action member is driven toward and away from the teeth when the toothbrush is operatively positioned within the mouth.  The action of the acoustic member is directly or indirectly coupled to the fluid in the mouth, producing a foam which couples shear forces between the acoustic action member and the teeth/gums to produce a desired cleaning/therapeutic effect.

Filed: 2006-10-18
Granted: 2009-02-10
Abstract: A method and apparatus for the removal of one or more lateral yarns from a woven industrial textile to prepare it for seaming. The apparatus comprises a movable table, a clamping device to hold the fabric, and a yarn removal device, comprising a cutter and a combined hooked needle and thread catcher. In operation, the yarn removal device moves both vertically into and out of the fabric plane, and horizontally parallel to the longitudinal yarns, piercing the fabric at two locations, cutting one or more yarns, and then grasping the cut section(s) to pull them down and out of the fabric plane. The cycle is repeated to form a longitudinal channel of desired length; the device is then moved laterally and the cycle repeated until an open channel parallel with the lateral fabric edge is accomplished, resulting in reliable seam preparation with reduced damage to remaining yarns.
