  • Patent number: 5981458
    Abstract: The disclosure is directed to novel detergent compositions having polyalkoxylated amine foam stabilizers. The new foam stabilizers of the inventive detergent compositions build or enhance foaming and are particularly useful because of their surprisingly mild, non-skin-irritating characteristics. Mildness is a requirement of components to be included in or used in applications such as liquid dish detergents, hand cleaners and car washes.

  • Patent number: 5972875
    Abstract: A pourable low-foaming alkoxylated amine oxide surfactant concentrate and method for making the concentrate are disclosed. The amine oxide concentrate has novel properties in that it is both highly concentrated and pourable at ambient temperatures. The amine oxides of the amine oxide concentrate include from about 3.5-30 moles of alkoxylated units and may be based on ether and/or fatty tertiary amine precursors. The low foaming properties and pourability of the amine oxide surfactant concentrate make the invention ideal for low-foam applications and for use in surfactant formulations.

  • Patent number: 5547525
    Abstract: Conductive carbon fibrils are incorporated into energetic compositions to reduce electrostatic discharge susceptibility. The carbon fibrils are grown catalytically from carbon precursors and are substantially free of pyrolytically deposited thermal carbon. The fibrils generally have a length in the range from about 1.mu. to about 10.mu. and a diameter in the range from about 3.5 nanometers to about 75 nanometers. Length to diameter aspect ratios are greater than 5, and typically in the range from about 100:1 to about 1000:1. An effective amount of fibrils is included in the energetic compositions to decrease the resistivity to a level below or on the order of about 10.sup.10 ohm-cm. In most cases, fibril concentration will be in the range from about 0.005 to about 0.1 weight percent.

  • Patent number: 5529648
    Abstract: Heterogeneous fuel compositions suitable for use in hybrid rocket engines and solid-fuel ramjet engines, The compositions include mixtures of a continuous phase, which forms a solid matrix, and a dispersed phase permanently distributed therein. The dispersed phase or the matrix vaporizes (or melts) and disperses into the gas flow much more rapidly than the other, creating depressions, voids and bumps within and on the surface of the remaining bulk material that continuously roughen its surface, This effect substantially enhances heat transfer from the combusting gas flow to the fuel surface, producing a correspondingly high burning rate, The dispersed phase may include solid particles, entrained liquid droplets, or gas-phase voids having dimensions roughly similar to the displacement scale height of the gas-flow boundary layer generated during combustion.

  • Patent number: 5500061
    Abstract: The addition of silicon (Si) powder from about 0.40 to 6.00 weight percent o ammonium nitrate (AN) propellant formulations as a fuel source results in a substantial increase in performance specific impulse (Isp). Theoretical Isp of AN propellant can be enhanced to levels approaching conventional in-service propellant formulations containing much more hazardous ingredients. Using inert or energetic polymer binders, AN propellant formulations are possible that will meet the performance requirements of most tactical missile systems when silicon is used as a fuel additive. Silicon powder when used to replace elemental carbon in most formulations has two major advantages: (1) an increase in theoretical Isp and (2) an improved propellant combustion efficiency by increasing propellant burning temperature. An improvement in propellant burning properties are also expected. The adjustment of weight percent ammonium nitrate in the AN propellant formulation is made as the silicon powder is adjusted over the range of 0.

  • Patent number: H1544
    Abstract: The addition of cathode materials comprising Cu.sup.++, Fe.sup.+++, Cr.sup.+++ or Au.sup.+++, in the form of salts such as the nitrate or halide, e.g. Fe(NO.sub.3).sub.3 or CuCl.sub.2, to low melting nitrate electrolyte cells increases cell potential. Other ions such as Co.sup.++, Eu.sup.+++, La.sup.+++, Ni.sup.++, Mn.sup.++, Ce.sup.+++, Pr.sup.+++, Nd.sup.+++, Gd.sup.+++, Sm.sup.+++ and Tb.sup.+++, in the form of salts thereof, can also be used, but yield smaller cell potentials. Such cathodic materials in the form of a suitable salt, such as a nitrate or halide, e.g. Fe(NO.sub.3).sub.3 or CuCl.sub.2, are added to low melting fused nitrate electrolytes, e.g. a LiNO.sub.3, KNO.sub.3 mixture, in a concentration sufficient to increase cell potential, using Li or Ca anodes. A suitable metal current collector such as a Ni screen can be used as a cathode. The above cathodic materials can be used in conjunction with other cathodic materials such as AgNO.sub.3, which undergoes reduction to the free metal.

  • Patent number: H1637
    Abstract: The fabrication of bipolar junction transistors in silicon-on-sapphire (SOS) relies upon the laser-assisted dopant activation in SOS. A patterned 100% aluminum mask whose function is to reflect laser light from regions where melting of the silicon is undesirable is provided on an SOS wafer to be processed. The wafer is placed within a wafer carrier that is evacuated and backfilled with an inert atmosphere and that is provided with a window transparent to the wavelength of the laser beam to allow illumination of the masked wafer when the carrier is inserted into a laser processing system. A pulsed laser (typically an excimer laser) beam is appropriately shaped and homogenized and one or more pulses are directed onto the wafer. The laser beam pulse energy and pulse duration are set to obtain the optimal fluence impinging on the wafer in order to achieve the desired melt duration and corresponding junction depth.
