    摘要： An improved method of producing a deposit of particles from a liquid medium carrier on a substrate for subsequent optical analysis of the particles, involves feeding the liquid medium carrying the particles to the substrate via a flexible tube which is not subjected to fluctuating lateral compressions. The invention has particular relevance to the making of Ferrograms from wear debris in a sample of machine lubricant.

    摘要： A clock has a clock face in the form of an axially symmetric solid, e.g. a sphere, a cone or a cylinder. Clock hands extend around the clock face following a helical path, and time-indicating markings are arranged on all the surfaces of the face. It is therefore possible for a complete set of these markings to be seen from any direction relative to the clock face. The hands are normally driven by a conventional clock movement, there being an hour hand and a minute hand. However, it would be possible in some applications to have only a single hand, e.g. a minute hand, and to drive the clock face relative to the hand. The markings are arranged along helical paths, corresponding to the helical shape of the hands.

    摘要翻译： 时钟具有轴对称固体形式的钟表面，例如。 球体，圆锥体或圆柱体。 时钟指针沿着螺旋路径延伸到时钟表面，时间指示标记布置在脸部的所有表面上。 因此，可以从相对于时钟面的任何方向看到一整套这些标记。 手通常由传统的时钟运动驱动，有一个时针和一只手。 然而，在一些应用中可能只有单手，例如， 一分钟的手，并相对于手驱动钟面。 标记沿着螺旋形路径布置，对应于手的螺旋形状。
