    • A process for etching a metal or alloy surface which comprises applying an etch-resistant ink by ink jet printing to selected areas of the metal or alloy, exposing the etch-resistant ink to actinic radiation and/or particle beam radiation to effect polymerisation, optionally thermally treating the etch-resistant ink and then removing the exposed metal or alloy by a chemical etching process wherein the etch-resistant ink is substantially solvent-free and comprises the components: A) 30 to 90 parts acrylate-functional monomers; B) 0 to 50 parts metal adhesion promoting organic compound; C) 0 to 20 parts polymer and/or prepolymer; D) 0 to 20 parts radical initiator, E) 0 to 5 parts colorant; and F) 0 to 5 parts surfactant; wherein the ink has a viscosity of not greater than 200 cPs (mPa·s) at 40° C., all parts are by weight and the total number of parts A)+B)+C)+D)+E)+F)=100, provided that where the metal or alloy is supported by a non-etchable substrate, it does not constitute a printed circuit board.
    • 一种用于蚀刻金属或合金表面的方法,其包括通过喷墨印刷将金属或合金的选择区域施加耐蚀刻油墨,将耐蚀刻油墨暴露于光化辐射和/或粒子束辐射以进行聚合,任选地 热处理耐蚀刻油墨,然后通过化学蚀刻工艺去除暴露的金属或合金,其中耐蚀刻油墨基本上无溶剂,并且包含组分:A)30至90份丙烯酸酯官能单体; B)0〜50份金属附着力促进有机化合物; C)0〜20份聚合物和/或预聚物; D)0〜20份自由基引发剂,E)0〜5份着色剂; 和F)0至5份表面活性剂; 其中油墨在40℃下的粘度不大于200cPs(mPa.s),所有份数均为重量份数,A)+ B)+ C)+ D)+ E)+ F )= 100,只要金属或合金由不可蚀刻的基板支撑,则其不构成印刷电路板。

    • An overflow chamber (2) is provided for use in a combined sewer overflow. An inlet (12) and an outlet (14) open into the chamber (2) below a screen (20), and an overflow outlet (15) opens into the chamber above the screen. Baffles (26) are provided underneath the screen (20) across the general flow of storm water. In storm conditions, the storm water in the chamber (2) will reach the level of the screen (20), which traps aesthetically offensive material and gross solids, leaving the water to flow through the screen (20) to the overflow outlet (15). The baffles (26) circulate the storm water, and this dislodges material accumulated on the underside of the screen (20) and so helps to prevent blinding of the screen (20) in storm conditions.
    • 提供溢流室(2)以用于组合的下水道溢流。 在屏幕(20)下方的入口(12)和开口(2)中的出口(14),并且溢流出口(15)通向屏幕上方的室中。 挡板(26)设置在屏幕(20)的下方,穿过一般的暴雨水流。 在暴风雨条件下,室(2)中的暴雨水将达到屏幕(20)的水平,这会捕获美观的材料和总固体,使水流过屏幕(20)到溢流出口(15) )。 挡板(26)使暴雨水循环,并且这会阻止积聚在屏幕(20)的下侧的材料,因此有助于防止屏风(20)在暴风雨条件下的眩光。
