  • Feedback-stabilized aerodynamically overbalanced lifting/control surface for aircraft
    Patent number: 5366176
    Abstract: An airfoil of an aircraft is provided with one or more control flaps which are pivotally mounted on the airfoil in an aeromechanically unstable manner. The trailing edges of the control flaps are provided with one or more control tab zones which include trailing portions that deform in response to application of electrical current, heat or pressure thereto. The pitch of the airfoil is constantly controlled by selectively deforming the control tab zones in response to measured signals indicative of variations in fluid pressure acting upon, or motion of the unstable control flaps. The impetus for moving the control system is thus derived from the air-stream through which the aircraft moves. The control system can also be utilized in watercraft, with the operating impetus being derived from the water stream through which the craft moves.

  • Fog-resisant mirror assembly
    Patent number: 5347106
    Abstract: The mirror assembly uses a reflective coating as a heating element for preventing fog formation on a mirror exposed to a humid environment such as is found in a bathroom. As compared to other typically reflective mirror coatings, the coating used in this invention has a relatively high resistance. The coating may be split into separate conductive elements with one or more scribe lines in order to control the length of the conductive path from inlet bus to outlet bus. The buses are made from an ultra thin foil tape which can be adhered to the reflective coating and which is solderable for securement of power lines thereto. The bus tape possesses both in plane and through plane conductive characteristics and can simply be cut to any length desired for the mirror sizes being produced.

  • Apparatus for indirect fluorescent assay of blood samples
    Patent number: 5342790
    Abstract: A patient's health is diagnosed by centrifuging blood samples in a transparent tube, which tube contains one or more groups of particles such as lyposomes or plastic beads of different densities for each group. Each group of density-defined particles carries antigens or antibodies which are specific to a complement antigen or antibody which may be in the blood sample being tested, and which are indicative of the patient's health. A label-tagged antibody which is specific to all bound antibody/antigen couples is added to the blood sample so as to form labeled antibody+antigen-antibody complexes (AAAC) in the blood sample. Upon centrifugation, the complexed particles will settle out in different areas in the tube according to the respective density of the particles, and the degree of label emission of the particle layers can enable qualitative or quantitative analyses of the blood sample to be made.

  • Differential erythrocyte counts
    Patent number: 5321975
    Abstract: Erythrocytes exist in vivo in a continuous cell subset gradient of density, with the youngest cells being the lightest. A blood sample is centrifuged in a transparent tube containing plastic beads which are selected to include groups of beads wherein each group has a different sharply defined specific gravity, and which are distributed within the range of red cell densities. The beads form spaced well-defined bands in the erythrocyte layer, which bands form boundaries between the different cell subset layers. Measurements of the lengths of the different cell subset layers are then made to quantify the red cell subsets in the patient's blood.

  • Fiberglass cloth resin tape insulation
    Patent number: 5274196
    Abstract: An improved electrical insulation tape is formed from a sheet of fiberglass cloth having a layer of thermoplastic resin bonded thereto. The thermoplastic resin layer is applied to the fiberglass sheet by melting the resin while contacting the fiberglass, and then the composite is cooled to bond the two components together. The composite sheet is then slit into tapes with substantially no unraveling of the fiberglass component at the slit edges of the tapes. The resultant tapes are easily wrapped on, and adhered to, conductors, such as magnet wire, or the like, by remelting and resolidifying the thermoplastic layer. The tape possesses excellent dielectric properties and heat dissipation properties. Alternatively, the fiberglass sheet may be impregnated with the melted thermoplastic component whereby a composite, rather than a relatively definitive two layer laminate, is formed.
