The wetting head wets the moisture activated adhesive on the side of the tape without contact between the side of the tape and the moisture releasing portion of the wetting head.

Abstract: By providing a fluid transfer assembly, two components forming bone cement are maintained separately from each other until actual intermixing thereof for use is desired, with the liquid monomer component being completely dispensed from a sealed unit directly into the mixing vessel in a closed loop manner, without exposure thereof to the user and without breakage of the container holding the liquid monomer, and a unique, multi-component, product handling and delivering system is achieved. In accordance with the present invention, the fluid transfer assembly is constructed for cooperating with the sealed vial or tube containing the liquid monomer and the mixing vessel for completely extracting all of the liquid monomer from the vial/tube in a closed loop operation and directly delivering the liquid monomer into the mixing vessel containing the dry powder. This transfer operation is achieved upon demand by the user, while preventing the liquid monomer from being exposed to the user or to the surrounding area.

Abstract: An intelligent fluid delivery system and method for controlling fluid delivery and monitoring parameters of fluid usage in a fluid jet printing system. The intelligent fluid delivery system (IFDS) includes the controls and electronic of the base station and fluid bottle. The replaceable base station, or nest, includes a micro-controller, independent of the main controller of the main printing system, for controlling fluid delivery and fluid management. The intelligent fluid delivery system provides a detection mechanism so that it can be ascertained with near certainty that an inserted fluid bottle is an appropriate fluid bottle having a fluid media that is compatible with the fluid jet printing system (e.g., within the specifications of the printing system and suitable for use with the other components of the ink jet printing system).

Abstract: An apparatus for folding and sealing a sheet having a pressure sensitive adhesive positioned thereon is disclosed. The apparatus includes a first roller and a second roller. The second roller has a roller surface, and a plurality of independent sealing protrusions extending from the roller surface. The sealing protrusions are positioned in operative contact with the first roller during advancement of the sheet between the first roller and the second roller. The apparatus yet further includes a third roller. The sealing protrusions of the second roller are positioned in operative contact with the third roller during advancement of the sheet between the second roller and the third roller. The sealing protrusions extend from the roller surface at locations such that advancement of the sheet between the second roller and the third roller causes the sealing protrusions to operatively contact the adhesive.

Abstract: By providing a single housing comprising a mixing chamber integrally combined with a delivery chamber or tube, a unitary, fully integrated, bone cement mixing and dispensing system is attained which eliminates user exposure or handling of the mixed bone cement. In the present invention, the two chambers of the integrated system are movable between two alternate positions, a first position wherein each chamber is sealed from the other, and a second position wherein the two chambers in direct communication with each other. In this way the mixing chamber is operated independently from the chamber for preparing the bone cement and, once prepared, is easily transferred from the mixing chamber through the delivery chamber. A dual drive assembly is provided such that it may an independently rotate a mixing blade in a first speed and direction, and independently drive the speed and rotation of a feed controlling element at a second speed and direction.

Abstract: Lower and upper covers permanently secured together form a vial enclosing chamber in a cap assembly which encloses the top of a bone cement mixing apparatus mixing chamber having prepackaged premeasured bone cement powder. The vial contains a monomer bone cement liquid and may be glass. The vial has two valve seats in corresponding ports on opposing vial side walls sealed by a releaseably secured preferably glass valve member threaded to a nozzle attached to the cap assembly. The vial ports are aligned with a mixing chamber liquid inlet port to permit the cement liquid to flow into the mixing chamber from the opened valves. The vial may be supplied enclosed in a separate package and includes valves on a valve stem attached to the package for opening and sealing the vial. In the alternative, the vial is frangible glass and may be opened by fracturing it and retaining the fragments in the vial receiving chamber to release the liquid to the mixing chamber.

Abstract: A method of forming an envelope in a document security apparatus includes the step of advancing a first enclosure sheet and a second enclosure sheet to a sealing station within the document security apparatus. The method includes the step of holding both the first enclosure sheet and the second enclosure sheet stationary relative to the sealing station. The method also includes the step of securing the first enclosure sheet to the second enclosure sheet during the holding step. A document security apparatus is also disclosed.

Abstract: A method of enclosing a confidential sheet in an envelope within a document security apparatus includes the step of operating a print engine so as to advance a first enclosure sheet therethrough. The method also includes the step of advancing the first enclosure sheet from an output of the print engine to a first position at a sealing station. The method further includes the step of advancing a second enclosure sheet to a second position at a sealing station. The method moreover includes the step of securing a first portion of the first enclosure sheet to a second portion of the second enclosure sheet at the sealing station so as to create the envelope having an access opening defined therein. The method also includes the step of operating the print engine so as to advance the confidential sheet therethrough.

Abstract: A sealing assembly for sealing an envelope having a first lateral side and a second lateral side includes a support roller. The envelope includes (1) a first enclosure sheet having a first pressure sensitive adhesive thereon, and (2) a second enclosure sheet having a second pressure sensitive adhesive thereon. The sealing assembly also includes a sealing member which is movable between the first lateral side and the second lateral side. The first pressure sensitive adhesive is urged into contact with the second pressure sensitive adhesive by interaction between the sealing member and the support roller when the sealing member is moved between the first lateral side and the second lateral side. A method of sealing an envelope having a first lateral side and a second lateral in a document security apparatus is also disclosed.

Abstract: Rifling for the barrel of a firearm includes a first gain twist region for increasing the rotational velocity of a bullet as it travels from the breech towards the muzzle end of the barrel, and a second region in which the rifling is of a constant twist so that the bullet exits the muzzle end of the barrel at a constant rotational velocity. The bore defined in the barrel is tapered in a direction from the breech end to the muzzle end so that the diameter of the muzzle opening of the barrel is less than the diameter of the breech opening. The angle of the rifling is variable with the rate of the gain twist of the rifling. The gain twist of the rifling in the barrel is formed by a button, preferably having a sinusoidal shaped periphery, which is pulled through the barrel during the manufacturing process. The smooth periphery of the button prevents shredding of the barrel when the button is twisted at different speeds to provide the variable gain twist of the rifling in different sections of the barrel.
