    • An applicator for applying liquids to surfaces, especially highly mobile liquids of low viscosity, the applicator comprising a cap-like body (30) in a transverse wall (50) of which is a dispensing aperture (60). An applicator pad (90) is bonded to the outside of the transverse wall and there is a diaphragm (70) on the other side of the transverse wall, covering the dispensing aperture. The diaphragm (70) has a slit (80), radially spaced from the dispensing aperture.An actuator member (100) extending through the dispensing aperture (60) rests with one end in contact with the diaphragm (70) and its other end in the applicator pad (90) so that pressure on the applicator pad (90) is transmitted via the actuator member (100) to displace the diaphragm (70) from the dispensing aperture (60) and open the slit (80).The applicator resists accidental discharge of liquid and is particularly useful for applying treatment liquids to the leather of shoe uppers to impart a shine.
    • 一种用于将液体施加到表面的施加器,特别是低粘度的高度移动的液体,所述施加器包括在横向壁(50)中的帽状体(30),其分配孔(60)。 施加器垫(90)结合到横向壁的外侧,并且在横向壁的另一侧上具有覆盖分配孔的隔膜(70)。 隔膜(70)具有与分配孔径向间隔开的狭缝(80)。 延伸穿过分配孔(60)的致动器构件(100)以与隔膜(70)接触的一端和其另一端搁置在施用器垫(90)中,使得施加器垫(90)上的压力经由 所述致动器构件(100)使所述隔膜(70)从所述分配孔(60)移位并且打开所述狭缝(80)。 涂抹器可防止液体的意外排出,特别适用于将处理液施加到鞋面的皮革上以赋予光泽。

    • A process for bleaching and/or providing limescale removal at a surface, by applying to that surface an aqueous composition having a pH of 2 or less and comprises a mixture of (a) an aqueous composition comprising hydrogen peroxide or an organic peracid having a pH of greater than 2 but less than 7 and (b) an acidic composition wherein components (a) and (b) are mixed not more than two hours before being applied to the surface requiring bleaching and/or limescale removal. The organic acid of component (a) has the formula XC (O)OOH where X is hydrogen or CH.sub.3 (CH.sub.2).sub.n and n is 0 to 8. The acid composition (b) comprises hydrochloric, sulphamic, tartaric, phosphoric, oxalic, citric, salicylic or ascorbic acids.
    • 一种用于在表面漂白和/或提供石灰垢去除的方法,通过向该表面施用pH为2或更低的水性组合物,并且包含(a)含有过氧化氢的水性组合物或具有pH的有机过酸的混合物 大于2但小于7,和(b)酸性组合物,其中组分(a)和(b)在施加到需要漂白和/或去除水垢的表面之前混合不超过2小时。 组分(a)的有机酸具有式XC(O)OOH,其中X是氢或CH 3(CH 2)n,n是0至8.酸性组合物(b)包括盐酸,氨基磺酸,酒石酸,磷酸,草酸, 柠檬酸,水杨酸或抗坏血酸。
