Abstract: A tape applicator (20) including housing, carriage, and blade assemblies (22;24;26). The housing assembly (22) includes a housing (40) and an application roller (42). The carriage assembly (24) includes a carriage body (120), a hub (122), and an idler roller (124). The carriage body (120) and hub (122) are slidably mounted within the housing (40). The idler roller (124) is rotatably mounted to the carriage body (120). The blade assembly (26) includes a blade arm (200), a blade (28), and a pressing finger (202). The blade arm (200) pivots relative to the housing (40) about a pivot axis. The blade (28) projects from the blade arm (200) to a tip. An articulation plane is defined by the blade tip and the pivot axis. The pressing finger (202) projects from the blade arm (200) through the articulation plane. The applicator (20) is transitionable between an application state and a cut state to sever tape (302) along an internal tape path.

Abstract: The present disclosure provides improved tape dispensers that include a tape roll housing featuring a sidewall and a surrounding, protective wall. At least a portion of the exterior surface of the surrounding wall includes at least one texture. The tape roll housing is coupled to a cutting edge support spaced from the roll housing. The dispensers can include a base defined by portions of the surrounding wall and the cutting edge support. In certain implementations, the based can include a concave portion.

Abstract: An adhesive tape dispenser is provided that includes a lower housing (200) that includes a pivot post (212) substantially perpendicular to a back wall of the lower housing, a back plate (230) assembly that includes a push button (244) assembly, a tape unwind spool (234), a lower pin (236), an upper pin (238), and a wedge (240) that is slideably engaged with the lower housing, and a blade assembly unit (260) that includes a cutter arm (262). The cutter arm includes a cutting blade (264) and a semi-tubular opening (270) that slideably engages the pivot post (212) of the lower housing. The cutter arm also includes an outer edge that guides along the wedge and lifts the forward end of the cutter arm (that includes the cutting blade) when the back plate assembly is urged forward by pressing the push button assembly forward.

Abstract: A tape dispenser comprises a tape roll housing comprising a tape dispensing mechanism. The tape dispensing mechanism comprises a dispenser opening in the housing, a moving cover connected to the housing by a hinge, a cutting edge located at the outermost edge of the moving cover, a first landing surface defining the edge of the dispenser opening closest to the hinge, and a second landing surface located on the moving cover adjacent to the cutting edge. The landing surfaces are configured such the tape is formed into a cross-web concave shape between the first landing surface and the second landing surface.

Abstract: An adjustable keyboard support assembly, which generally includes a housing comprising a first side panel having a first guide rail system and a second side panel spaced from the first side panel and having a second guide rail system. The assembly further includes a generally U-shaped member comprising a support member with first and second ends, a first side arm attached to the first guide rail system and extending from the first end of the support member, wherein the first side arm comprises at least one notch, and a second side arm attached to the second guide rail system and extending from the second end of the support member, wherein the second side arm comprises at least one notch. The first and second side arms have rotatable and slideable connections with the guide rail system of their respective side panels. A keyboard platform is rotatably attached to the support member of the U-shaped member.

Abstract: An electrofiltration process is provided having at least one electrostatically charged polymeric film layer having surface structures. The film layers may be configured as a collection cell that has the structured film layer defining a plurality of ordered inlet openings through a face of the collection cell and corresponding air pathways, thereby forming an open, porous volume. The air pathways are defined by a plurality of flow channels formed by the structured film layers. The electrofiltration process is coupled with an ionizer which actively induces charges onto the particles to be removed by the collection cell.
