  • Patent number: 9175854
    Abstract: A flameless lighter provides a user with a heat source that is similar to typical lighter. The flameless light comprises an enclosure, a slidable switch, a light assembly, a portable power supply, and a switch retraction mechanism. The enclosure is the primary structural component of the flameless lighter. The light assembly is used to produce the necessary heat to ignite items such as cigarettes and candle wicks. The slidable switch is used to activate and deactivate the light assembly and is used to protrude and retract a light bulb into and out of the enclosure. The portable power supply is used electrically power the light assembly and can be recharged through a universal serial bus charging port. The switch retraction mechanism defaults the slidable switch to the “OFF” position so that the flameless light is not left in the “ON” position. This improves the overall safety of the flameless light.

  • Patent number: 4840770
    Abstract: Odor control product dispenser includes a cabinet having a removable front cover for directly accessing both an upper fan compartment and a lower product compartment from the front. A fan in the fan compartment draws air in through a fan shroud surrounding the fan and directs the air downwardly into the product compartment for flow across an exposed surface of the odor control product in the second compartment and subsequent discharge through air vents in the front and sides of the cabinet. The odor control product is contained in a well in one end of a disposable container. Within the well are a plurality of circumferentially spaced pinwheel type baffles that increase the turbulence of the air flowing across the product as the product evaporates to accelerate the rate of evaporation as the product loses its potency (effectiveness) with age.

  • Patent number: 4797254
    Abstract: A sheltered-type protection means for process instrumentation/automation, particularly quality measuring equipment for industrial processes with a hazardous environment and materials is described, which has a self-supporting housing with an extractable support member, on which is arranged at least one analyzer, a sample preparation means, an auxiliary material system and a unidirectional or bidirectional communications means for electrical signals. This arrangement permits a very compact construction and ensures that after extracting the support member unimpeded access to the individual components is possible. The invention also has the advantage that as a result of the small dimensions of the housing, it can be constructed in an extremely tight manner, so that the interior thereof is scavenged e.g. with an inert gas and can be kept under overpressure without leakage losses occurring.

  • Patent number: 4743406
    Abstract: A self-contained battery-powered room deodorizer including a housing having an inlet portion through which ambient air is drawn into the housing by means of a battery powered fan. The air is passed about a quantity of vaporizable material contained within the housing, and then discharged therefrom into the ambient air carrying the vaporized portion of the product therewith. A replaceable deodorizing material containing cartridge is positionable within the housing, and provides a support well for supporting a replaceable battery, such that the deodorizing material and battery may be separately replaced when either of these items has become expended.

  • Patent number: 4734265
    Abstract: In a gas generator for a vehicle protection system having an outer jacket and an inner housing attached thereto through an edge union and consisting of an ignition carrier and a thin-walled propellant vessel, which inner housing together with a primer and a propellant charge forms a hermetically encapsulated separate structural unit, an edge lip of the ignition carrier bent radially inward over the collar type enlarged propellant vessel edge is provided, which, when the inner housing is installed in the outer jacket, is pressed axially against a stepped abutment surface of the outer jacket and is thereby held in tight press-fit engagement on the collar-like vessel edge. Due to this the gas generator has, in terms of manufacture, a very simple construction in the region of the ignition carrier attachment to the propellant vessel but yet is highly burstproof.

  • Patent number: 4695429
    Abstract: An exhaust gas purification device for installation in the exhaust line of an internal combustion engine of a vehicle, for igniting and vaporizing particulate matter in the exhaust stream. The device includes a canister having a tubular casing with an open end, and an end fitting having a wide mouth which fits against the open end, and thereby closing off the same. The fitting has an inlet port for connection to the exhaust pipe of the engine. Disposed within the casing is a porous filter element which traps small amounts of solid matter such as soot, and keeps it from entering the atmosphere through the vehicle's tailpipe. Igniting devices in the canister adjacent the inlet side of the filter, are located along the exhaust stream flowpath. Upon contact with the igniting devices, at least some of the particulate matter in the stream is vaporized, and passed, as a gas, through the filter.

  • Patent number: 4692306
    Abstract: A compact concentric-tube catalytic reaction apparatus for converting distillable hydrocarbon feedstock or methanol to useful industrial gases, such as hydrogen and carbon monoxide, comprises an annular reaction chamber concentrically disposed around an internal burner chamber. An infrared burner assembly vertically disposed within the burner chamber provides a uniformly radiating source for heat transfer to the reaction chamber. The burner chamber employs a convective section of enhanced thermal efficiency. The present invention eliminates the problems of flame impingement and local heat maldistribution associated with compact designs employing flame burners directly radiating to the reaction chamber wall.
