    • A dimmable electrical discharge lamp providing radiation and having a CRI of over 90 and a color temperature of between about 3000-4000° K even when dimmed by up to 40% of its rated power. The lamp contains a fill of a mixture of cesium, mercury and a rare gas. The fill is enclosed in a hermetically sealed polycrystalline alumina arc tube having an electrode at each end and the arc tube is enclosed in an outer jacket. The lamp is provided with a circuit for providing current to the arc tube. A low frequency wave simmer current is provided and one or more current pulses are superimposed on the simmer current. The gradient of the leading edge of the pulse is short whereby to generate a high electrical field and cause a high degree of ionization of the cesium.
    • 提供辐射的可调光放电灯,其CRI大于90,颜色温度在约3000-4000°K之间,即使在其额定功率达到40%的情况下也是如此。 该灯含有铯,汞和稀有气体混合物的填充物。 填充物封闭在密封的多晶氧化铝发光管中,每个端部具有电极,并且电弧管被封装在外护套中。 该灯具有用于向电弧管提供电流的电路。 提供低频波模拟电流,并将一个或多个电流脉冲叠加在煨电流上。 脉冲前沿的梯度较短,从而产生高电场并引起铯的高度离子化。

    • A combustion chamber of the type employing staged combustion principles is disclosed. Effective control of undesirable pollutants is sought over a wide range of operating power levels. A specific objective is to separate staged combustion zones without the penetration of structural apparatus into the chamber. Single site fuel injection is desired.Primary fuel premixing tubes (34) and secondary fuel premixing tubes (38) terminate at the front wall (32) of the combustion chamber (30). The primary fuel premixing tubes have highly angled discharge swirlers at the downstream ends thereof. The highly angled swirlers (66) cause the fuel/air mixture emanating therefrom to burn in close proximity to the front wall. The secondary fuel premixing tubes have lowly angled discharge swirlers, or no swirlers at all, so as to cause the effluent therefrom to penetrate the region at which primary combustion is taking place without significantly influencing the fuel/air ratio at the primary combustion site (P).
    • 公开了一种采用分级燃烧原理的燃烧室。 在广泛的工作功率水平下寻求对不良污染物的有效控制。 具体目的是分离分段的燃烧区,而不会使结构装置进入腔室。 需要单点燃料喷射。 主燃料预混合管(34)和二次燃料预混合管(38)终止于燃烧室(30)的前壁(32)。 初级燃料预混合管在其下游端具有高度倾斜的排放旋流器。 高角度旋流器(66)使得从其喷出的燃料/空气混合物在靠近前壁的地方燃烧。 二次燃料预混合管具有低角度喷射旋流器,或完全没有旋流器,从而使其流出物渗透到正在发生初级燃烧的区域,而不显着影响主燃烧位置处的燃料/空气比(P )。
