摘要： A shingle is provided having a headlap section and a buttlap section with at least one portion of the buttlap section having a relatively uniform color and another portion of the buttlap section having a color gradient or gradation from light to dark. An illusion of depth or thickness is created on the portion of the buttlap section having the color gradient. The buttlap section defines in part the exposed weather surface of the associated shingle. The relatively uniform color portions may be formed on tabs or dragon teeth and the color gradient formed on a backer sheet disposed beneath the tabs. Openings between adjacent tabs expose the color gradient to view. A plurality of horizontal striations may be used to establish the desired color gradient from light to dark. The amount of tone and contrast may be selected to create the desired illusion of depth or thickness. The amount of contrast may be varied depending upon the color selected for each shingle. The number of horizontal striations and their width may also be varied to provide the desired color gradient.

摘要： A system for the continuous dielectrophoretic separation of mixtures of particulate and granular materials by passing the materials through a divergent electric field created in a fluid dielectric medium by applying a voltage to an electrode configuration including a rotatable cylindrical-shaped electrode having a non-uniform conductor surface and a stationary perforate electrode spaced therefrom to define a contact zone. The particles having dielectric constants lower than that of the fluid medium are collected through the perforate electrode while those particles having dielectric constants higher than that of the fluid medium are attached to and separated by the rotatable electrode.

摘要： A shingle is provided having a headlap section and a buttlap section with at least one portion of the buttlap section having a relatively uniform color and/or value and an adjacent portion of the buttlap section having a value gradation from light to dark. A plurality of horizontal striations with transition stripes disposed between adjacent horizontal striations may be used to establish the desired value gradation. An illusion of depth or thickness is created on the portion of the buttlap section having the value gradation. The buttlap section defines in part the exposed weather surface of the associated shingle. The relatively uniform color and/or value portions may be formed on tabs or dragon teeth and the value gradation formed on a backer sheet disposed beneath the tabs. Openings between adjacent tabs expose the associated enhanced value gradation to view. The amount of contrast between adjacent striations may be substantively increased to create the desired illusion of depth or thickness while the transition stripes provide a subtle change in value from one striation to the next striation. The number of horizontal striations and their width may also be varied to provide the desired value gradation.
摘要翻译： 提供了一种垫板，其具有头部部分和对接部分，其中对接部分的至少一部分具有相对均匀的颜色和/或值，并且对接部分的相邻部分具有从亮到暗的值等级。 可以使用多个具有设置在相邻水平条纹之间的过渡条纹的水平条纹来建立所需的值灰度。 在具有值渐变的对接部分的部分上产生深度或厚度的错觉。 对接部分部分地定义了相关屋顶的暴露的天气表面。 相对均匀的颜色和/或值部分可以形成在翼片或龙牙上，并且形成在设置在翼片下方的底板上形成的值等级。 相邻选项卡之间的开口会暴露相关的增强值渐变以进行查看。 相邻条纹之间的对比度可以被大大增加以产生深度或厚度的期望的错觉，而过渡条纹提供从一个条纹到下一条纹的价值的微妙变化。 水平条纹的数量及其宽度也可以变化以提供期望的值等级。
