Abstract: A flexural assemblage and method for inspecting a highly sensitive surface using a probe flexibly fixed in close proximity to the sensitive surface pivots away from the moving web surface when a surface protuberance contacts the probe. An armature element of the flexural assemblage contains one or more probes. The armature is biased against movement, but the force of the moving protuberance when contacting the probe overcomes the bias and pivots the probe and armature away before damage results to the web surface or web carrier.
Abstract: An apparatus for bursting perforations on an article has a retractable burst member and an opposed second retractable burst member that imposes an impact force on the perforations on the perforated lid. Retractable burst members are arranged for vertical movement towards and away from one another in a common plane. The article is positioned in a plane substantially perpendicular to the movement of the burst members so that the burst members can engageably contact the article at the perforations. A separator is used to capture the perforated lid at the burst perforations and then retract for separating the perforated lid from the main portion of the article.

Abstract: A cassette for storing and dispensing objects arranged in a stack, such as end disks, has a base plate, a plurality of standoffs attached to the base plate, and a stripper plate having a removed concentric section attached to ends of the standoffs. A hub member is centrally positioned in the base plate and extends towards the central opening of the stripper plate. A biased support plate attached to base plate is in slidable contact with the hub member for supporting a portion of the loading side of an end disk resting thereon. End disks are removed for independent processing one at a time through a removed section in the stripper plate by a stream of air directed between the loading side of the top most end disk and the unloading side of the nearest adjacent end disk in the stack.

Abstract: An apparatus and method for centering a film spool or similar object. A quill or object support means arranged on either inboard and outboard ends a frame are used to engage end portions or flanges of the film spool. A pivot member provides translational simultaneous movement of both quills toward and away from the spool. The quills move equidistant relative to the centerline of the spool so that the centerline of an incoming web to be wound thereon will always align with the centerline of the spool.

Abstract: An apparatus for bursting perforations on an article, such as a corrugated box, has a rotatable, retractable burst member that exerts an impact force on opposing sides of end portions of the perforated lid. Burst member is arranged for vertical movement towards an end portion of the perforated lid and then rotatable movements to opposing sides of the perforated lid. The article is positioned in a plane substantially perpendicular to the movement of the burst member so that the burst members can engageably contact end portions of the perforated lid with a predetermined impact force. A separator is used to capture the perforated lid and then retract for separating the perforated lid from the main portion of the article.

Abstract: An assemblage for aligning a roll to a chucking device has at least two flexibly movable, spaced roll support members arranged planarily for supporting the roll for alignment with a fixed positioned chucking device. Each roll support member has a compression head biased for movement by a plurality of cooperating spring members. Precise alignment of the core with the chucking device results from the force imparted to the flexibly movable support member bearing the roll by the chucking device engaging the core.
Abstract: A method of controlling fluid flow in a microfluidic process includes the step of providing a piezoelectric pumping apparatus (100) in fluid communications with the microfluidic process such as an ink jet printer and the like. The piezoelectric pumping apparatus (100) has a piezoelectric transducer (80) with a functionally gradient piezoelectric element (60) arranged in a fluid containment chamber (120) which fluidically communicates with the microfluidic process. The functionally gradient piezoelectric element (60) responds to a voltage applied by a power source (240) by either expanding to expel fluid from the microfluidic process or contracting to permit fluid to enter the fluid containment chamber (120) and thus the microfluidic process.

Abstract: A method of engraving a gravure cylinder having a circumference C for coating a liquid composition on a substrate. The liquid composition contains a concentration of particles having a predetermined particle diameter. The method includes calculating the engraving channel depth Do based on a first ratio of the particle diameter to channel depth (DB/Do). Then, engraving the gravure cylinder according to &thgr;, &agr;, WC, Ww, and Wo.

Abstract: A coating feed apparatus and method (10) for depositing a uniform overflow curtain-like layer of coating composition (c) to a gravure surface (14) has a reservoir (14) and means for delivering the coating composition to the gravure surface (14). The reservoir (14) has a base (24) sloped upwardly from a rear wall (22). A widthwise lip (40) is directed generally downwardly towards the gravure surface (14). Widthwise lip (40) and the undercut portion (48) together enable the coating composition (c) exiting the outlet end (26) of the reservoir (12) to overflow downwardly across widthwise lip (40) in a uniform curtain-like layer (32) towards the gravure surface (14) without creating a backflow of coating composition along the base (24).

Abstract: A time-temperature indicator device comprises a polymeric layer having a first and second surface and a dye composition adhered to said first surface comprising a dye which diffuses into the polymeric layer as a result of a cumulative time-temperature exposure wherein the dye is invisible when viewed in visible radiation and is detectable as a result of absorption of non-visible radiation. The device may be attached to a product for monitoring cumulative time-temperature exposure.
