Abstract: An air bearing sheet heater assembly provided for heating a sheet in an ink imaging printer includes (a) a heater plate including a heating element, and having a front side defining a first side of a sheet path through the heater assembly; (b) at least one movable platelet having a back surface, and an opposite front surface facing the heater plate and defining a second side of the sheet path; and (c) an air bearing assembly mounted to the at least one platelet for creating an air bearing between the second side and the first side of the sheet path by pneumatically spacing the front surface of the at least one movable platelet from the front side of the heater plate, thereby reducing stiction forces and friction along the sheet path through The air bearing sheet heater assembly.

Abstract: A print head reservoir for use in an ink jet printer includes a body, an ink bucket, and a filter. The body defines an ink cavity. The cavity includes a cavity inlet, a cavity outlet and a vent positioned above the cavity inlet for bleeding air from the ink cavity. The ink bucket attaches to the body. The ink bucket communicates with the cavity via the cavity inlet. The filter is disposed in the cavity dividing the cavity into an upstream filter cavity and a downstream filter cavity.

Abstract: A neck flange supports a tracheostomy tube inserted into the neck and has a neck engaging portion of a molded thin flexible flat sheet of a transparent polymer. An interconnection positioned centrally within the neck engaging portion and carried thereby has a ring shaped body with an opening and a pair of opposed pivot pins extending inwardly into the opening for carrying the tube passing therethrough. The pair of opposed pins fit for movement within recesses in the tube to permit limited swivel motion. The interconnection is molded of a transparent polymer material that is less flexible than the neck engaging portion and has a stepped cross section so the pair of opposed pivot pins are raised relative to the ring shaped body. The neck engaging portion is molded about the interconnection so the raised pair of opposed pins remain exposed.
