  • Patent number: 10774483
    Abstract: A device to protect a structural member against a cutting threat, such as a saw blade or thermal cutting device, is provided. The device provides a substrate having a cavity disposed therein. A cutting resistant element is disposed within the cavity to impede cutting of a cutting device, such as a saw blade or thermal cutting device, into the cutting resistant element.

  • Patent number: 10495654
    Abstract: Methods and system capable of processing specimens carried by slides within an automated histological staining system. A slide carrier is moved toward and into a temperature-controlled internal environment of a stainer within the system. The slide carrier carries a first slide and a second slide, and the first and second slides can carry a first specimen and a second specimen, respectively. The first and second specimens are stained with at least one of a staining reagent and a counterstaining reagent while the first and second slides are within the internal environment and while an average temperature of the internal environment is greater than ambient temperature. The slide carrier can be moved out of the internal environment after staining one or both specimens.

  • Publication number: 20090230081
    Abstract: A liner for a wine bottle cap is constructed such that a gas, such as oxygen, that diffuses through the liner moves along a path within the liner whose length is greater than the thickness of the liner. In this manner, oxygen from the atmospheric air can diffuse through a relatively thin liner at a slow rate before reaching the bottled wine. The liner is comprised of alternating layers of material semi-permeable to oxygen and material impermeable to oxygen, the impermeable layers containing open areas through which oxygen can diffuse. As oxygen diffuses through the alternating layers, the path(s) along which the oxygen diffuses is determined by the locations of the open areas in the impermeable layers. The liner may be assembled with a screw cap closure that comprises ventilation holes connected by a raceway for distribution of atmospheric air to the liner.

  • Patent number: 6854274
    Abstract: Systems and methods are provided for controlling the rotational speed of a turbogenerator in stand-alone mode to account for a present operating load and a transient reserve capability. A base speed set point may be received, comprising a baseline speed setting for the turbogenerator. A speed offset may be determined comprising an adjustment to the base speed set point required to accommodate the transient reserve capability. An adjusted speed set point may be produced by combining the base speed set point and the speed offset. The rotational speed of the turbogenerator may then be set to the adjusted speed set point.

  • Patent number: 6408611
    Abstract: A control system and method for controlling the split between premix fuel flow and pilot fuel flow to a combustor in a gas turbine engine so that an acceptable emissions are maintained. Engine speed and exhaust gas temperature are used to obtain a combustor pilot zone temperature that will result in the desired level of emissions. From this pilot zone temperature a desired split between premix fuel flow and pilot fuel flow is obtained and compared to the actual split to generate an error signal. The actual premix fuel flow and pilot fuel flow are then adjusted until the desired split and hence the desired emission levels are obtained.
