    摘要: An RF receiving circuit that selectively attenuates a received RF signal before it reaches sensitive modifying devices, such as a low noise amplifier or an analog to digital converter. The receiving circuit includes a delay element upstream of its attenuator so that high energy pulses of a short duration (for example, less than 10 nanoseconds) can be effectively attenuated despite coupler, detector, threshold and/or switch delays of the attenuation related circuitry.

    摘要: Systems and methods are provided for implementing risk retention programs for originators and securitizers of asset backed securities. An administrative contract identified as a margin as credit enhancement contract is created for a corresponding asset backed security. A risk retention entity is assigned a long position for the margin as credit enhancement contract corresponding to a predetermined percentage of the asset backed security. A buyer of the asset backed security is assigned a short position for the margin as credit enhancement contract. When the asset backed security expires, a computer device settles the long and short positions of the margin as credit enhancement contract.

    摘要: An apparatus for the treatment of 100% reclaimed asphaltic pavement (RAP) uses low temperatures and no direct radiation from a burner flame to the RAP. The RAP is first heated in a counter flow drum which is supplied with hot combusting gases generated by a remote low NOx burner. The temperature of the drum input gases is preferably around 1100 degrees F and the output temperature of the gases may be 100 degrees F or less greater than the input temperature of the RAP. The RAP may be heated with a microwave oven to raise the RAP to a final temperature, although this step is not absolutely necessary in the counterflow design of this invention.

    摘要: Novel systems and methods for selectively listing a commodity under one or more different commodity codes are provided. A single commodity may be selectively listed under different commodity codes based upon whether it is offered on an opening or closing basis. The commodity may be an Interest Rate Swap (IRS). It may be matched with bids according to a fixed rate variable when listed under the first code. The same commodity may then be listed on the same exchange under a second commodity code. In one embodiment, the commodity listed under the second commodity code may be matched with bids according to a different variable, such as, for example, a currency amount. In one implementation, the currency amount of the second variable may represent a non-par payment.

    摘要: An apparatus and process is provided for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) of up to 100% of the HMA comprised of reclaimed asphaltic pavement (RAP). The HMA is first heated in either a parallel or a counter flow rotating drum which is supplied with hot combustion gases generated by a remote low NO.sub.x burner. The temperature of hot gases entering the drum is from about 400.degree. to 2,000.degree. F., and the temperature of gases exiting from the drum is from about 130.degree. to 220.degree. F. The HMA material optionally can be subjected to microwave radiation to raise the material to a final temperature, or optionally to only reorient the dipolar molecules of the material without any measurable heating of the material. The exhaust gas is treated and made environmentally safe. The hot gases exiting from the drum are passed through a knockout box and then through a baghouse having acrylic bags coated with a protective layer of particulate material. The gases exiting the baghouse are passed through an oxidizer to further remove smoke and asphaltic material and at least a portion of the gases from the oxidizer are recycled through a heat exchanger.
