  • Patent number: 8329477
    Abstract: A method and system for releasing active ingredients into the surrounding atmosphere is disclosed. In one embodiment, the dispersion rate of the active ingredient through the membrane is passively regulated by adjusting the porosity of the membrane. In another embodiment, materials with microfluidic channels of various diameters are interposed together so that the configuration of the channels approximates a venturi, thereby improving the flow of the solution through the microfluidic channels. In another embodiment, heat is applied to the top membrane layer to further accelerate the rate at which fluid is dissipated through the membrane structure. Devices incorporating membranes with the disclosed properties are also presented.

  • Patent number: 8328569
    Abstract: An adapter for connecting a 600 ampere deadbreak bushing to a pull-on and pull-off deadbreak elbow used for normally non-current carrying applications. The adapter comprises a two part separable assembly having first and second ends. The first end is threaded to mate with a threaded opening in the deadbreak bushing and the second end is threaded to mate with a threaded opening in a lug of the deadbreak elbow. The two part separable assembly is coupled together with the first part of the assembly that is screwed into the deadbreak bushing and has a groove that snaps (latches) into a corresponding latching ring in a molded insert of the deadbreak elbow that surrounds the second part of the assembly screwed into the lug inside of the deadbreak elbow. Other latching mechanisms may be used to mechanically and electrically couple together the first and second parts of the adapter assembly.

  • Patent number: 8331066
    Abstract: A circuit breaker for a transformer includes means for interrupting circuitry in the transformer upon a fault condition in the transformer (the “fault interruption means”). The circuit breaker also includes means for interrupting the circuitry when a level of dielectric fluid in a tank of the transformer is unacceptably low (the “low oil trip means”). The fault interruption means includes a magnet, metal element, and first actuator. Upon the fault condition, the magnet and metal element separate, moving the first actuator to cause the electrical circuitry to open. The low oil trip means includes a float, insulating rod, and second actuator. When the dielectric fluid level drops to an unacceptably low level, the float and insulating rod drop, moving the second actuator to cause the circuitry to open. The low oil trip means operates independently of the fault interruption means, opening the circuitry without separating the magnet and metal element.

  • Patent number: 8329072
    Abstract: Sulfur (or sulphur) spray nozzles disposed with a cooling tank spray liquid molten sulfur into the cooling liquid in the tank. Solid sulfur seeds are formed in the cooling liquid and settle in the tank. The cooling tank may be a spiral dewaterer tank that has a screw conveyor at the bottom of the tank that moves the seeds to a granulating drum for enlargement into sulfur granules. The cooling tank may also be used to capture and remove sulfur dust from a slurry of sulfur dust and water recycled from the granulating drum. The sulfur dust in the cooling tank may be captured by contact with molten sulfur droplets streaming down the cooling liquid column such that the dust particles become incorporated into the droplet, thereby being converted to seed. The granulating drum may be equipped with two or more sets of segmented lifting flights. The sets of flights may not be in alignment. The flights may be spaced apart from the inside surface of the drum with segmented rib members.

  • Patent number: 8332738
    Abstract: Methods for enforcing group oriented workflow requirements for multi-layered documents. Embodiments allow results of multi-layered operations to dictate the flow of tasks that occur on a multi-layered document. Flow is directed to roles and may be directed by the data values operated on in addition to multi-layered operation results. The system enables the workflow enabled creation and maintenance of multi-layered documents that minimize repeated data to ensure the highest possible data integrity when targeting a publication at multiple audiences. When a publication is changed and requires maintenance, use of a defined workflow for updating the publication ensures consistency in each publication. Embodiments may comprise performance metrics for monitoring and benchmarking publication processes.

  • Patent number: 8330235
    Abstract: Transistor devices are formed with nickel silicide layers formulated to prevent degradation upon removal of overlying stress liners. Embodiments include transistors with nickel silicide layers having a platinum composition gradient increasing in platinum content toward the upper surfaces thereof, i.e., increasing in platinum in a direction away from the gate electrode and source/drain regions. Embodiments include forming a first layer of nickel having a first amount of platinum and forming, on the first layer of nickel, a second layer of nickel having a second amount of platinum, the second weight percent of platinum being greater than the first weight percent. The layers of nickel are then annealed to form a nickel silicide layer having the platinum composition gradient increasing in platinum toward the upper surface.

  • Patent number: 8331217
    Abstract: A ground- or roof-top-based repeater in an OFDM system uses multiple transmission antennas to transmit multiple identical OFDM signals. Dithering is performed by introducing a slight variable-frequency phase offset to all but one of the multiple identical transmitted OFDM signals. The effective overall channel is more dynamic and provides spatial diversity to minimize long periods of fading in fading subchannels of the OFDM signals when the receiver is in a slow moving or stationary situation. To overcome the additional cancellation problem that can occur when two or more of the transmitting antennas are (i) in a line-of-site position with the receiver and (ii) approximately the same distance from the receiver, a delay is deliberately introduced to make the delayed signals appear to be reflected signals. This delay will not negatively impact the OFDM receiver performance as long as the delay is within the guard interval used in the OFDM process.
