  • Patent number: 10404649
    Abstract: Systems, methods, and computer program products for determining network characteristics are provided. The network characteristics may be used to facilitate changes to how content is delivered over a network, such as to avoid network congestion, to provide improved throughput, or to provide a good (or better) user experience, such as when streaming media. For example, the network characteristics may be determined, in part, by tracking domain name resolution requests by using specially formulated domain names that require resolution at an authoritative name server.

  • Patent number: 10118830
    Abstract: Segregation of silicon granules in the fluidized bed production of polycrystalline silicon is achieved by successively transferring granular polycrystalline silicon through a plurality of vessels designed for funnel flow of granular material. The transfers may occur prior to introduction of feed particles into the reactor, or the enlarged granules from the reactor may be thus transferred to improve product size uniformity.

  • Patent number: 9731325
    Abstract: Disclosed is mobile mechanical xeriscape gravel cleaner which is delivered to the site of the xeriscaping to be cleaned by a wheel/axle assembly, leveled with adjustable jack stands mounted on the metal frame. Xeriscape material to be cleaned is collected and deposited in a hopper with slide plate to control flow of material into the receiving chamber. Using an external power system, the auger/screener device rotation begins and picks up and carries forward the material, passing through the transition plate to the auger/cleaner chamber where foreign material passes through the screen. The cleaned material proceeds to the discharge chamber where it is collected and returned to the original xeriscaped site. The mobile mechanical xeriscape gravel cleaner can clean xeriscape gravel at a lower cost, with improved quality and a higher rate of speed than was previously possible, with significantly reduced burden to the ecosystem.

The particles slide downwardly acquiring a velocity according to their shape. A gap between a lower edge of the inclined surface and a first receiver is sized such that only particles having more than a predetermined velocity are capable of traversing the gap to the first receiver. The remaining particles fall through the gap and into a second receiver.

The method involves separating coarse and fine components of the waste. The apparatus uses several devices, separately or in combination, to separate the components, such as a sieve, auger, and blower. The coarse components are conveyed by auger, gravity or other means to be measured by weight in a first hopper. The fine components are conveyed by gravity, blower, auger or other means to be measured by volume in a second hopper. Fresh materials may be added to both hoppers. The materials from both hoppers are then mixed together in a primary mixing chamber and finally conveyed into molds for curing before use.

A raking device in the hopper section rakes the top of the body of particles prior to entering the extruder section. The raking device rakes in a direction opposite to the movement of the body of particles. The raking device can be raised and lowered to change the level of the particles, and thus the density. The raking device also forms the top of the body of particles with upwardly tapered corners. A plate located below the hopper and extruder sections supports the lower conveyor belt. The heat section uses steam chambers with a perforated top, which also serves to support the conveyor belt.

    Abstract: A continuous gasification furnace and method of operation. The charge is fed into the furnace chamber between two rolls at least one of which is driven. The furnace chamber can be sealed from the ambient atmosphere. The bed of the furnace contains three zones from top to bottom, these zones are; a volatilization zone, a char reaction zone and an ash zone. Additionally, there can be a drying zone above the volatilization zone. Fuel, air, and steam enter the lower portion of the furnace through strategically located inlet ports. Fuel is used to start up the burning bed while carefully controlled steam to air ratio is used during continuous operation of the furnace. Simultaneously controlled steam cooling effects and exothermic reactions occur in the char reaction zone whereby all or controlled amounts of the oxygen is consumed so that pyrolysis can occur in the volatilization zone without the danger of combustion in that zone or combustion of the fumes leaving the bed.
