An apparatus and method for depositing an aerosol that has an ultrafast pneumatic, shutter. The flow of aerosol through the entire deposition flow path is surrounded by at least one sheath gas, thereby greatly increasing reliability. The distance between the aerosol switching chamber and a reverse gas flow chamber input is minimized to reduce switching time. The distance from the switching chamber to the nozzle exit is also minimized to reduce switching time. The gas flows in the system are configured to maintain a substantially constant pressure in the system, and consequently substantially constant flow rates through the deposition nozzle and exhaust nozzle, to minimize on/off switching times. This enables the system to have a switching time of less than 10 ms.

The ring binding mechanism includes one or more partial rings which are slidably mounted in arcuate tracks in a base plate member for rotational movement between a loading position wherein an opening between the ends of the rings is accessible to install or remove sheets of paper or the like and a loaded position wherein the opening is located beneath the surface of the base plate member. The tracks, base plate member and rings include parts which cooperate to releasably lock the rings in the loaded position. In one embodiment, the ring binding mechanism is installed on a one-piece cover including a spine section defined between laterally spaced hinged sections. The spine section is either mounted directly on the base plate member or sandwiched between the base plate member and a back plate member which are secured together with snap-in fingers. The binder can be transported in an unassembled condition and assembled at the point of use by the user.

A registry device for transparencies for an overhead projector comprises a backbone with at least two projections for entering openings in a transparency to prevent it from moving; and, an adhesive-free anchoring sheet of plastic attached to the backbone. The anchoring sheet being of a material that will cling to the glass stage of a projector and prevent the registry device from sliding or being moved until the anchoring sheet is lifted from the glass. In a preferred embodiment a framing sheet also is attached to the backbone.

An extension platform for holding a book of transparencies in an operative position on an overhead projector includes a body member adapted to receive and hold a pack of transparencies, at least two suction cups positioned on the underside of the body member for attaching and securing the body member to the stage area of an overhead projector and wedge-shaped fulcrum means located under the body member which translates the downward gravitational force of the weight of the pack of transparencies into an upward pull on the suction cups. In another embodiment, the extension platform is attached to part of a book of transparencies.

A flexible binding blank is die-cut from a sheet of polyethylene terephthalate to form a tape with bands projecting at right angles from one edge. In one embodiment, the tape has a perforated longitudinal center line with rectangular apertures opposite each band, and a coating of pressure sensitive adhesive. The bands are threaded through apertures in a stack of pages, and folded back so that free ends of the bands project through the rectangular apertures. In one embodiment, the tape is folded along its perforated center line securing the bands into rings, and projecting free ends cut off. In another embodiment, the bands are notched to engage notches in the tape.
