A burner apparatus (10) for a process heating system (400) includes a combustion air damper (48) to control the volume of air in the combustion chamber (98). Top (15), bottom (17), and sidewalls (14) of the chamber are of steel without refractory material lining while a fuel door (178) is steel with refractory material lining (186). A flue gas damper (34) selectively allows or disallows flue gas out of the chamber. A cooling jacket (18) of a steel sheeting surrounds and is narrowly spaced from the combustion chamber top, bottom, and sidewalls. The cooling jacket conducts air, transfers heat from the combustion chamber top, bottom, and sidewalls to thereby prevent overheating, and generates heated air. A turbulation device (38) combines flue gas and heated air into a turbulent air-gas mixture, completes combustion, and outputs a heated gas stream.

A planar antenna includes a ground plane on a substrate, a radiating element coupled to the ground plane on the substrate, and a feed line. An impedance tap point is defined by a connection between the feed line and the radiating element and the length of the radiating element defines the resonant frequency of the antenna. A first portion of the radiating element includes an impedance adjustment mechanism for defining the impedance tap point of the antenna and consequently the impedance of the antenna. A second portion of the radiating element includes a frequency adjustment section which adjusts the length of said radiating element and consequently the resonant frequency of the antenna.

A method for incentivizing a user of a social media website to share an offer with others within an online social media environment is provided. The offer includes two coupons, the first coupon having a first value and the second coupon having a second increased value. Sharing of the first coupon provides access to the second coupon and also creates a social media connection between the user and a vendor of the first and second coupons.

A wideband tuneable low noise amplifier that is capable of receiving signals over a wide range of frequencies, providing tuneable filtering to remove out of band interferer signals, and providing variable gain for a wide range of frequencies. To accommodate variable gain, the low noise amplifier has an amplifier stage comprising two gain stages, and the relationship between the gain stages is controlled responsive to changes in the voltage gain of an input stage. Linearity monitoring combined with Q-enhance may be employed to increase performance at low signal levels.
摘要:
A process and apparatus for extraction of zinc from a material containing one or more iron oxides and zinc oxide which facilitate heating a composite body of the material and a carbonaceous material in a reduction zone. The reduction zone contains a reducing atmosphere at a temperature insufficient to effect melting of the iron in the material but at a temperature and for a time sufficient to form a reductant from the carbonaceous material and to reduce a predetermined amount of the zinc oxide to zinc vapor. The process and apparatus also facilitate collecting the zinc vapor and cooling it to form liquefied or solid zinc.

A device for coupling to other devices and unique identification thereof may include a body and a coupler. The coupler may be disposed on the body and may be operable to couple to a coupler of another device. The device may include a test circuit and a processor for recognizing other devices. The processor may be operable to determine the presence of a particular device within a chain of devices by controlling the inputs of the test circuit and monitoring the outputs of the test circuit. The device may include a circuit element for uniquely identifying the device when the device is coupled to one or more of the other devices.
摘要:
Systems and methods are provided for translating between bills of material based on an identifier associated with a component definition and a function definition. The component definition and the function definition are a component and function definition for a bill of material such that another component from that bill of material having a different function does not satisfy the component and function definition.
