An insulation blanket is disclosed that contains fire-blocking materials for preventing rapid penetration of fire into an aircraft fuselage in case of a fire outside the aircraft. The insulation blanket contains at least one layer of fiberglass or other thermal-acoustic insulation material without fire-blocking properties, and one or more layers of fire-blocking material. The fire blocking material is wider than the thermal-acoustic insulation so that it may be folded against and attached to adjacent structural frame members of the fuselage. In the alternative, a thermal-acoustic insulation material is used that has fire-blocking properties instead of the separate layers of fire-blocking and thermal-acoustic insulation materials. A method for installing insulation blankets according to the present invention is disclosed, whereby a fire-blocking insulation portion of the blanket is folded against and attached to frame members of the aircraft using attachment posts or spring clips.

A method for the oxidation of substrates comprising treating an aqueous, basic solution of a substrate having an oxidizable functionality using an elemental halogen as terminal oxidant in the presence of an oxoammonium catalyst/halide co-catalyst system. Use of elemental halogen, preferably chlorine gas or elemental bromine, unexpectedly allows oxidation without significant degradation of the substrate. The substrate is preferably a monosaccharide, oligosaccharide, or polysaccharide, and the oxidizable functionality is preferably an aldehyde, hemiacetal, or a primary alcohol. An effective source of the oxoammonium catalyst is 2,2,6,6-tetramethylpiperidinyl-1-oxy (TEMPO) and a particularly economical and effective catalyst is 4-acetylamino-2,2,6,6-tetramethylpiperidinyl-1-oxy.

A microfluidic chip formed with multiple fluid channels terminating at a tapered electrospray ionization tip for mass spectrometric analysis. The fluid channels may be formed onto a channel plate that are in fluid communication with corresponding reservoirs. The electrospray tip can be formed along a defined distal portion of the channel plate that can include a single or multiple tapered surfaces. The fluid channels may terminate at an open-tip region of the electrospray tip.

An automated pharmaceutical or biotech compound testing system uses a very small molded plastic shelf keeping unit or test tube known as a “minitube”. The minitubes are stored in trays in a standing refrigeration unit and are retrieved by a machine or robot having a die cutting tubular end effector adapted to selectively cut away and remove a minitube from an integrally molded matrix containing hundreds of minitubes (e.g., 384). Upon cutting a selected minitube away from the matrix, the end effector is pushed down over the selected minitube, thus forcing the minitube into the cylindrical interior lumen of the end effector, where it is retained by friction fit until such time as the minitube is to be releaseably locked into a plastic receiving tray. Minitubes are stored in the plastic tray which is adapted to receive and releaseably hold or lock the tubes in place.
