    • An oven comprises a cooking chamber, first and second energy sources, a cooling fan, and a controller. The first energy source provides radiation heating in the cooking chamber, and the first energy source has a low mass for rapid heating. The second energy source provides convection heating in the cooking chamber, and the second energy source has a high mass heating element and a convection fan for moving air through the cooking chamber during convection heating. The cooling fan moves cooling air over the first energy source. The controller energizes the first and second energy sources during at least initial convection heating so that the first energy source rapidly heats the cooking chamber in order to facilitate the initial convection heating and to eliminate the need to pre-heat the cooking chamber.
    • 烤箱包括烹饪室,第一和第二能量源,冷却风扇和控制器。 第一能源在烹饪室中提供辐射加热,并且第一能量源具有用于快速加热的低质量。 第二能源在烹饪室中提供对流加热,并且第二能量源具有高质量加热元件和用于在对流加热期间通过烹饪室移动空气的对流风扇。 冷却风扇将冷却空气移动到第一能量源上。 控制器在至少初始对流加热期间激励第一和第二能量源,使得第一能量源快速加热烹饪室,以便于初始对流加热,并且消除对烹饪室预热的需要。

    • A moisture content measuring apparatus and method wherein a sensor station produces calibration data corresponding to measurements of light at two different wavelengths reflected from a material, and the calibration data is then transferred to a hand held computer. The moisture content of a sample of the material is measured and input to the hand held computer. The process is repeated after changing the wetness of the material, and the hand held computer creates a table correlating reflection data to moisture content. The table is transferred to the sensor station which then continuously generates signals representing moisture content in response to real time reflection data and the table. The cost effectiveness of the sensor stations readily facilitates the use of a dedicated sensor station at each of a plurality of conveyors carrying different materials to be combined into a composite of predetermined proportions by weight. Based on the real time moisture contents of each material, the respective flow rates are adjusted to compensate for moisture in order to produce the predetermined proportion.
    • 一种水分含量测量装置和方法,其中传感器站产生对应于从材料反射的两种不同波长的光的测量的校准数据,然后校准数据被传送到手持式计算机。 测量材料样品的含水量并将其输入到手持计算机中。 在改变材料的湿度之后重复该过程,并且手持计算机创建将反射数据与水分含量相关联的表格。 该表被传送到传感器站,该传感器站响应于实时反射数据和表,连续地产生表示湿度含量的信号。 传感器站的成本效益容易地使得在携带不同材料的多个输送机中的每一个处使用专用传感器站来组合成预定重量比的复合材料。 基于每种材料的实时水分含量,调节各流量以补偿水分以产生预定比例。
