    • 7571. Miller, F. R., and Millergraph Co. March 31. Photo-mechanical printing-surfaces; negatives, producing by means other than by photography. -Relates to the production of a combined screen and base on which negatives are made by hand or mechanical means, which negatives perform a two-fold function, namely that of a negative and that of a screen, and are more especially applicable for making half-tone printing-surfaces. A sheet of celluloid or other relatively soft but tough material is formed with a series of tapering or pyramidal-shaped projections. A coating of ink is applied to the apexes of these projections and a coating of translucent material such as a solution of shellac containing red colouring-matter is applied to the whole surface. The coatings at the apexes are then removed by rubbing with a rag soaked in turpentine leaving a series of light openings. The negative can then be made by tracing and with an air brush, or by scraping away the projections and producing openings of variable diameter in accordance with the light and shade of the picture to be reproduced. Component colour negatives for colour printing are similarly made.

    • A fluid lens includes a refractive interface positioned between two transparent plates where at least one surface of one of the plates has a fixed radius of curvature configured to compensate for aberration produced by the fluid lens. The refracting interface can be formed by a meniscus formed between two immiscible liquids or by a membrane positioned between two fluids. A method of reducing aberration of a fluid lens includes determining a fixed radius of curvature for at least one surface of one of the plates that is sufficient to compensate for aberration produced by the fluid lens.
    • 流体透镜包括位于两个透明板之间的折射界面,其中这些板之一的至少一个表面具有固定的曲率半径,该曲率半径被配置为补偿由流体透镜产生的像差。 折射界面可以通过在两种不混溶液体之间形成的弯月面或通过位于两种流体之间的膜来形成。 一种减小流体透镜的像差的方法包括确定一个板的至少一个表面的固定曲率半径,该曲率足以补偿流体透镜产生的像差。

    • A reflective grating (24) for precision location measurement is disclosed. In one embodiment, the reflective grating has a non-reflective substrate (56) and a non- reflective adhesion layer (28) disposed on the substrate layer. A reflective surface layer (30) is disposed on the adhesion layer. In another embodiment, the reflective grating is manufactured on the reflective (polished) surface of a monolithic substrate. A series of grating lines (32) are formed in the reflective surface layer by vaporizing portions of the reflective surface layer with a laser in order to expose the non-reflective adhesion layer. Accordingly, alternating reflective and non reflective grating lines are formed that are used for making precision measurements.
    • 公开了一种用于精确定位测量的反射光栅(24)。 在一个实施例中,反射光栅具有非反射衬底(56)和设置在衬底层上的非反射粘附层(28)。 反射表面层(30)设置在粘合层上。 在另一个实施例中,反射光栅制造在单片基板的反射(抛光)表面上。 通过用激光蒸发反射表面层的部分以便暴露非反射粘附层,在反射表面层中形成一系列光栅线(32)。 因此,形成用于进行精密测量的交替的反射和非反射光栅线。
