  • Patent number: 6883518
    Abstract: A unidirectional valve, wherein the valve comprises a valve body including a frame, a valve opening through the frame, and a valve seat extending from the frame and at least partially surrounding the valve opening. The valve further includes a valve flap having a first portion attached to the frame and an adjacent second portion free to move from a first position where the second portion is in contact with at least a part of the valve seat to a second position where at least part of the second portion is spaced from the valve seat, wherein the valve flap has a nonuniform thickness. The thickness variations may occur between sides of the valve flap, and may also occur between the ends of the valve flap.

  • Patent number: 6666209
    Abstract: A method and apparatus for calibrating the air flow in a respirator system is provided. The method provides for the establishment of control set points in a true calibration protocol through the simple triggering of the microprocessor of a controller. When the trigger is initiated, the microprocessor engages and provides the logic for the calibration cycle. The calibration cycle proceeds until a second trigger terminates the process and establishes the control set points. The calibration sequence of the method relies only on an initiation and termination trigger that is facilitated by components integral to the apparatus.

  • Patent number: 6632311
    Abstract: A method of making a roll of adhesive tape that comprises providing a length of tape having a leading end, a trailing end, a first side, and a second side opposite the first side, wherein the second side of the tape is at least partially covered with pressure sensitive adhesive and providing a tab having first and second opposite ends having a length between them, a first side, and a second side, wherein at least a portion of the second side of the tab is covered with pressure sensitive adhesive. The method further comprises advancing the length of tape along a tape path, positioning the leading tape end about a central tape roll axis, and circumferentially winding the length of tape about the axis until a penultimate tape layer having a circumference is wound.

  • Patent number: 6544640
    Abstract: A method of applying repositionable pressure-sensitive adhesive sheets to moving articles includes aligning a plurality of articles for sequential movement through a sheet application station. Each article has at least two different sheet landing areas defined on a common surface thereof A repositionable pressure-sensitive adhesive sheet from a first applicator is applied at the sheet application station onto a first landing area of every other article as it passes the sheet application station. A repositionable pressure-sensitive adhesive sheet from a second applicator is applied onto a second different landing area on all of the remaining articles as they pass through the sheet application station. The resultant stack of articles formed in this way does not have all of the note sheets aligned vertically in the stack, thus reducing the overall height of the stack by dispersing horizontally the added thicknesses of the note sheets on the articles.

  • Patent number: 6536728
    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.

  • Patent number: 6436713
    Abstract: The invention relates to methods for determining whether or not to discard a sample of oil based on the presence of polar compounds in oil and devices to be used to determine the presence of polar compounds in oil. In a preferred embodiment, a test strip comprising an adsorbent affixed to a backing is spotted with a polar indicator. A sample of oil is positioned on a heat conducting device supporting the test strip and the oil is allowed to migrate over the adsorbent material, thereby displacing the polar indicator in an amount related to the amount of polar compounds in the oil. This displacement is correlated to the amount of polar compounds in the sample.

  • Patent number: 6430299
    Abstract: A headset assembly includes an electronics housing and a replaceable battery. The battery includes a recessed region for limiting contact between the battery housing and the electrical contacts of the electronics housing. The contacts of the battery include raised regions for concentrating the electrical contact regions between the battery and the electronics housing, and to further clean the electrical contacts of the electronics housing during slideable insertion of the battery into the electronics housing.

  • Patent number: 6382206
    Abstract: A speech transmission adapter and a respirator mask comprising a speech transmission adapter. The respirator mask comprises an inhalation port, an exhalation port, and a speech transmission adapter in detachably sealed engagement with the inhalation port. The adapter comprises a peripheral housing, a speech reception means supported by the peripheral housing, and a speech transmission means operably coupled to the speech reception means. The speech reception means receives sound pressure generated by a wearer of the respirator mask, and the speech transmission means conveys signals representative of such sound pressure to an external speech transducer. The adapter mates to the inhalation port of a respirator mask and expands the clean air envelope defined within the mask to include the speech reception means within the clean air envelope without requiring structural modification of the respirator mask.

  • Patent number: 6383591
    Abstract: A method and apparatus for sequentially and precisely registering cut sheets for application onto advertising signatures at high speeds employs an initial roll of sheeting material. The sheeting material is unwound to track a process path, where eyemarks on the sheeting material are detected for use in registering the sheeting material to be cut into discrete sheets and to be aligned with a moving advertising signature for affixation thereto. The sheeting material has a repositionable pressure sensitive adhesive along one side edge thereof for use in adhering the cut sheet to the advertising signature. In one embodiment, the sheeting material is generally opaque adjacent one side edge and is sufficiently transparent adjacent its other side edge so that when a sheet cut from the sheeting material is adhered to an advertising signature, images on the advertising signature are visible through at least a portion of the sheet.

  • Patent number: 6367521
    Abstract: A dispensing valve cap mountable to a bottle is provided with a first valve part having a tubular portion having an air inlet and a fluid outlet spaced apart along a longitudinal axis of the tubular portion to form a constant head valve for dispensing fluid from the bottle. A second valve part of the valve rotatably mounted to the first valve part includes a tubular portion for simultaneously closing both the air inlet and the fluid outlet of the first valve part when fluid dispensing is not desired. The second valve part firther includes an air inlet, and a fluid outlet alignable with the air inlet and the fluid outlet of the tubular portion when fluid dispensing is desired. The dispensing valve cap controls fluid flow from the bottle. The bottle with the valve cap is useable with a dispenser assembly for mixing a concentrated fluid from the bottle with a dilutant. A tamper resistant lock prevents undesired rotation of the second valve part relative to the first valve part.
