Abstract: One or more techniques and/or systems are disclosed for a vent-free heater that may be installed in an area used for human occupancy, to provide heat to that area. Such a heater can comprise an environmental detector that senses ambient air conditions, and may provide data used to shut down the heater in predetermined threshold condition. In one implementation, a vent-free heater for installation in high altitudes can comprise a combustion region and a fuel supply component. The heater can comprise an environmental detector with a flameless sensor configured to detect an ambient level of a constituent of the atmosphere and generate a signal indicative of the constituent level; and a sensor interface that can control flow of fuel from the fuel supply, based at least upon a signal received from the sensor.

Abstract: One or more techniques and/or systems are disclosed for a portable heater that may be used in an area used for human occupancy, to provide heat to that area. Such a heater can be portable, and comprise an environmental detector that senses ambient air conditions, and may provide data used to shut down the heater in threshold conditions. In one implementation, a portable heater for use in high altitudes can comprise a housing configured for portability, in which a combustion region and a fuel supply component are disposed. The heater can comprise an environmental detector with a flameless sensor configured to detect an ambient level of a constituent of the atmosphere, and generate a signal indicative of the constituent level; and a sensor interface that can control flow of fuel from the fuel supply, based at least upon a signal received from the sensor.

Abstract: A multifunctional naphthol-based epoxy resin composition which is a reaction product of a) a naphthol which is a reaction product of i) from 1 to 99 weight percent 1-naphthol and ii) from 1 to 99 weight percent 2-naphthol; and b) an epihalohydrin, is disclosed. Also disclosed is a curable composition comprising: a) an epoxy component comprising the multifunctional naphthol-based epoxy resin composition; and b) a hardener component comprising i) a phenolic resin component selected from the group consisting of phenol novolac resins, triphenolalkane phenolic resins, aralkyl phenolic resins, biphenyl phenolic resin, biphenyl aralkyl phenolic resins, substituted naphthalene phenolic resins unsubstituted naphthalene phenolic resins, and combinations thereof; and ii) a phosphorus-containing composition which is the reaction product of an etherified resole with 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO).

Abstract: A cover for obstructing the camera of an optical head mounted display is provided. The cover comprises a sleeve having a cavity adapted to slide over an optical head mounted display camera. The sleeve removably attaches to the optical head mounted display camera via snap connectors located within the cavity of the sleeve. The sleeve is sufficiently flexible to accept insertion of the optical head mounted display camera and securely retain the optical head mounted display camera therein. The cover further includes an indicator on an exterior surface thereof designating that the optical head mounted display camera is not operational.

Abstract: Embodiments include curable compositions including an epoxy resin and a hardener component including a terpolymer having first constitutional unit, a second constitutional unit, and a third constitutional unit, where the epoxy group to the second constitutional unit has a molar ratio in a range of 1.0:1.0 to 2.7:1.0. Embodiments include prepregs that include a reinforcement component and the curable composition and an electrical laminate formed with the curable composition.

Abstract: Provided is a forced air heater. The forced air heater may comprise a housing defining a duct. The duct may be adapted for a flow of fluid therethrough. The heater may be adapted to provide a flow of fluid through the duct that is substantially laminar or transient.

Abstract: The invention relates to a method, apparatus and system for the treatment of organic and inorganic waste in a waste fluid. The method involves a co-current plug flow of fluid in a reactor in which ozone mass transfer conforms to the effective life of the ozone used in the treatment. Hydroxide and hydrogen peroxide can be added to the waste fluid. The combined fluids to be treated travel the reactor through a series of surfaces in a packed reactor. The apparatus includes a diffuser for ozone which assists in the co-current plug flow of fluids. The diffuser can have a porosity of about 10 microns. The invention further envisions a compact system for efficient treatment of waste fluids.

Abstract: A novel nickel-carbon electrode, and methods for making the same, have been developed. The nickel-carbon electrode comprises an active mass (e.g., a nickel oxyhydroxide, hydroxide or oxide) deposited to a carbon foam using any one of chemical deposition, thermal deposition or electrochemical deposition. The nickel-carbon electrode is formed or “activated” through a series of charge-discharge cycles. The nickel-carbon electrode is comparable in volumetric capacities (mAh/cc) with commercial nickel electrodes but higher in gravimetric capacities (mAh/g). The nickel-carbon electrode may be used in rechargeable nickel-based batteries which have applications in cordless appliances, portable devices, standby power systems, the aerospace industry, and hybrid electric vehicles.

Abstract: A polymerization process comprises (1) contacting at least one polymerizable monomer in the presence of a metal catalyst in a reactor; (2) effectuating polymerization of the monomer; (3) adding a substituted olefin having at least one polar group to the reactor. The substituted olefin is different from the monomer. Vinyl-terminated macromers preferably are generated which can be homopolymerized or copolymerized with the monomer by the metal catalyst. A polymer of an olefin monomer and a substituted olefin comprising a backbone and a plurality of side chains. The polymer is characterized by an Rv of greater than about 0.85, where Rv is a measure of the relative number of vinyl groups in the polymer. In some polymers, the vinyl endgroups are transformed to other useful end groups.
