An office work system comprises a first furniture unit having a first laterally-extending channel, and a second furniture unit having a second laterally-extending channel, the second channel being disposed substantially parallel to and at least substantially the same vertical height as the first channel, such that at least a portion of the first and second channels coextend. The office work system further comprises a work accessory and a connector assembly to connect the work accessory to the first and second furniture units along the coextending portions of the channels, the assembly including a pair of engagement members adapted to engage the first and second channels.

An acoustic driver horn that is integral to a wall of a cavitation chamber is provided. The horn design is applicable to any of a variety of cavitation chamber configurations, including spherical, cylindrical, and rectangular chambers. Although a variety of driver assemblies can be coupled to the driver horn, preferably the acoustic driver assembly includes a head mass, a tail mass, and at least one transducer, typically a piezoelectric transducer, and preferably a pair of piezoelectric transducers. A groove in the cavitation chamber wall defines the driver horn and separates it from the remaining portion of the cavitation chamber wall. Due to the thinning of the wall around the horn, the driver that is attached to the horn is able to more effectively couple its energy into the cavitation fluid within the chamber.

An hourglass-shaped cavitation chamber is provided. The chamber is comprised of two large spherical regions separated by a smaller cylindrical region. Coupling the regions are two transitional sections which are preferably smooth and curved. The chamber can be fabricated from either a fragile material, such as a glass, or a machinable material, such as a metal. A ring-shaped acoustic driver is coupled to one end of the cavitation chamber, preferably using an epoxy or other adhesive. If desired, a second ring-shaped acoustic driver can be coupled to the second chamber end. Coupling conduits which can be used to fill/drain the chamber as well as couple the chamber to a degassing and/or circulatory system can be attached to one, or both, ends of the chamber.

A corrugated box finishing machine has a station where dust, debris and other particles are cleaned from the corrugated boards before they are conveyed to the printing station. Electrostatic charges on the particles are neutralized by a static bar and the particles are then removed from the boards by a rotating brush. The particles are drawn into a vacuum chamber underlying the path of conveyance of the boards, and the static bar is positioned in an enclosure in proximity to the boards but isolated from the vacuum in the vacuum chamber. The enclosure has surfaces which direct the particles away from the static bar which is oriented to further minimize contact with the removed particles. The cleaning brush includes a plurality of brush sections mounted on a rotatable shaft made from carbon fiber material. Downstream of the cleaning brush a plurality of magnets extend transversely adjacent the path of conveyance to attract and remove metallic particles from the boards as they are conveyed to the printing station.

An acoustic driver assembly for use with any of a variety of cavitation chamber configurations, including spherical and cylindrical chambers as well as chambers that include at least one flat coupling surface. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass. The end surface of the head mass is shaped to limit the contact area between the head mass of the driver assembly and the cavitation chamber to which the driver is attached, the contact area being limited to a centrally located contact region. The area of contact is controlled by limiting its size and/or shaping its surface.

An acoustic driver assembly for use with a spherical cavitation chamber is provided. The acoustic driver assembly includes at least one transducer, a head mass and a tail mass, coupled together with a centrally located threaded means (e.g., all thread, bolt, etc.). The driver assembly is either attached to the exterior surface of the spherical cavitation chamber with the same threaded means, a different threaded means, or a more permanent coupling means such as brazing, diffusion bonding or epoxy. In at least one embodiment, the transducer is comprised of a pair of piezo-electric transducers, preferably with the adjacent surfaces of the piezo-electric transducers having the same polarity. The surface of the head mass that is adjacent to the external surface of the chamber has a spherical curvature greater than the spherical curvature of the external surface of the chamber, thus providing a ring of contact between the acoustic driver and the cavitation chamber. The area of the contact ring is increased in one embodiment by chamfering a portion of the head mass such that the chamfered surface has the same curvature as the external surface of the chamber. In at least one embodiment, a void filling material is interposed between one or more pairs of adjacent surfaces of the driver assembly and/or the driver assembly and the exterior surface of the cavitation chamber.

Coupling the regions are two transitional sections which are preferably smooth and curved. The chamber can be fabricated from either a fragile material, such as a glass, or a machinable material, such as a metal. An acoustic driver assembly is coupled to one end of the cavitation chamber, preferably using a threaded means (e.g., bolt or all-thread/nut), an epoxy joint, a diffusion bond joint, or a braze joint. If desired, a second acoustic driver assembly can be coupled to the second chamber end. Preferably the driver or drivers are attached such that their central axis is coaxial with the central axis of the cavitation chamber. Coupling conduits which can be used to fill/drain the chamber as well as couple the chamber to a degassing and/or circulatory system can be attached to one, or both, ends of the chamber. When used, preferably the conduit or conduits are attached off-axis.

Coupling the regions are two transitional sections which are preferably smooth and curved. The chamber can be fabricated from either a fragile material, such as a glass, or a machinable material, such as a metal. A ring-shaped acoustic driver is positioned around the outer circumference of one of the two large cylindrical regions of the cavitation chamber. Preferably the driver is held in place with an epoxy or other adhesive. If desired, a second ring-shaped acoustic driver can be positioned around the outer circumference of the second of the two large cylindrical regions of the cavitation chamber.
