    • 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.
    • 一种用于处理加热系统(400)的燃烧器装置(10)包括用于控制燃烧室(98)中的空气体积的燃烧空气阻尼器(48)。 腔室的顶部(15),底部(17)和侧壁(14)均为不含耐火材料衬里的钢,而燃料门(178)为耐火材料衬里(186)的钢。 烟气阻尼器(34)选择性地允许或不允许烟道气从腔室中排出。 钢板的冷却套(18)包围并与燃烧室顶部,底部和侧壁间隔开。 冷却套管传导空气,从燃烧室顶部,底部和侧壁传递热量,从而防止过热,并产生加热空气。 紊流装置(38)将烟道气和加热的空气混合到湍流空气 - 气体混合物中,完成燃烧并输出加热的气流。

    • 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 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.
    • 宽带可调低噪声放大器,能够在宽范围的频率范围内接收信号,提供可调滤波以去除带外干扰信号,并为广泛的频率提供可变增益。 为了适应可变增益,低噪声放大器具有包括两个增益级的放大器级,响应于输入级的电压增益的变化来控制增益级之间的关系。 可以采用与Q增强相结合的线性监测来提高低信号电平下的性能。
