  • Patent number: 6770693
    Abstract: This invention discloses blends of phosphites comprising bis-(2,4-dicumylphenyl) pentaerythritol diphosphite and hindered phenol antioxidants useful as stabilizers against thermooxidative degradation of polymers during melt processing. Polymer compositions comprising the blends show improved resistance to thermooxidative degradation during melt processing as measured by melt flow index and yellowness index.

  • Patent number: 6763647
    Abstract: The invention relates to window framing systems which seal against exterior surfaces, particularly embossed surfaces. The system is held together with a plurality of screws. The inner component of the frame contains at least one hollow void having a V-shaped strut which provides additional structural support to the inner component and minimizes any dimpling or screw breakthrough due to the use of automatic screwdrivers having a torque which is in excess of the mechanical strength of the inner frame member.

  • Patent number: 6722584
    Abstract: The invention relates to an improved design for a spray gun and application system for cold gas dynamic spraying of a metal, alloy, polymer, or mechanical mixtures thereof. The gun includes a rear housing comprising a powder inlet and a gas inlet, a front housing removably affixed to the rear housing and comprising an mixing cavity therein for mixing of the powder and gas and an exit therefrom, a nozzle holder having a bore disposed therethrough and removably affixed to the front housing, and a nozzle positioned within the nozzle holder, an interior taper of the nozzle holder bore complementing an exterior taper of the nozzle, said nozzle having an initially converging, subsequently diverging centrally disposed bore therein adapted to receive the mixed powder and gas from the mixing chamber.

  • Patent number: 6691898
    Abstract: The invention relates to a fluid dispensing device incorporating a push-button actuator normally biased in the closed position, a housing for receiving the aerosol canisters and a carrying case for the entire assembly. Activation is achieved by longitudinal axial compression followed by snapping engagement of the housing fitted about the aerosol valves which depresses the aerosol valves.

  • Patent number: 6676781
    Abstract: The invention relates to a thermoplastic panel or piece having a resilient welded portion. The panel or piece of the present invention may be used in a variety of applications such as to provide sealing ends on thermoplastic panels or to create resiliently closable passages in thermoplastic panels through which wires and other objects may be passed while maintaining an even surface appearance of the baseboard panel. Other uses include attaching one or more thermoplastic pieces together. The invention also includes a method for making the subject thermoplastic panel or piece.

  • Patent number: 6648635
    Abstract: A portable heater adapted for use in a recreational enclosure or temporary work enclosure includes a housing having an air inlet on the lower front face. A gas supply is partially enclosed by the housing which provides propane to the mouth of a burner venturi located within the housing. Air is drawn through the air inlet and also enters the mouth of the burner venturi. The air and gas are mixed thoroughly as they travel upwardly through the burner venturi. A chimney effect increases fresh air flow velocity into the burner venturi and allows the heater to operate at a reduced fuel gas pressure. Upon exiting the burner venturi, the air/gas mixture is to a plenum and radiant surface where combustion takes place. Any conventional means may be provided to ignite the air/gas mixture in order to cause combustion. The combustion products deflect off a deflector, which is cooled on a rear face by air flow through the housing, which decreases the temperature of the combustion products before exiting an outlet.

  • Patent number: 6618957
    Abstract: The invention described herein pertain generally to a process for drying and/or pathogen reduction as well as an apparatus effective for the same, the process comprising the steps of feeding a sample containing water onto a mesh conveyor belt; transporting the sample into a heated chamber having an air flow about, around and through the sample; exposing said sample to at least two sources of microwaves in non-parallel alignment to each other; and collecting the sample. The at least two sources of microwaves are from a split waveguide assembly, producing microwaves which are essentially 90° out of phase to each other. The heated chamber is between approximately 75° C. and 125° C. The convection heating supplements the microwave heating thereby both heating the sample from the outside in and also from the inside out. The microwave frequency is between 915 MHz and 1000 MHz, preferably approximately 915 MHz.

  • Patent number: 6609349
    Abstract: The invention relates to window framing systems which use corner keys, and which seal against embossed surfaces, particularly for use in garage doors. The corner keys are insertable into hollow portions of extruded window frames and which preliminarily hold the window frame together prior to more permanent fastening within a garage door by a plurality of screws or even via a snap-fit arrangement. The angularity of at least two internal ribs of the corner key into which a fastener impinges thereupon, facilitates tightening engagement of each mitered window frame corner, leading to a superior appearance and preventing moisture from getting inside the window unit by the positioning of a sealing surface which seals on an edge of a door or panel.

  • Patent number: 6357154
    Abstract: A label holder for general merchandising has a pair of resilient fingers which permit it to be clipped onto a lower flange of a shelf. The holder is bottom-loading and includes an opaque back portion of durable plastic and a transparent window portion, the two extruded portions uniting along an upper edge. The window portion is generally coextensive with the back portion and preferably extends past the lower edge thereof Two sets of rigid ribs overlap in the space between the back portion and the window portion and interact to clamp an upper edge of a label retaining it in place until removal or relocation is desired.
