摘要： A water hydrant is provided with a number of valves operable to eliminate freezing problems and to prevent backflow into potable water, thereby precluding the danger of contamination. Water and air valves operate in conjunction such that trapping of water in the hydrant is averted by the admission of air after each closing of the water valve. By a somewhat different arrangement in outlet spout valving, air is also admitted to the spout after each closing of the water valve or other reduction in water pressure, the spout valving having the additional feature of blocking backflow, all of which meets the anti-contamination requirements of the hydrant.
摘要翻译：消防栓设有多个可操作的阀，可以消除冷冻问题，防止回流进入饮用水，从而排除污染的危险。水和空气阀联合操作，使得在每个关闭水阀之后，通过吸入空气来避免消防栓中的水的捕获。通过在出口喷口阀门中有一些不同的布置，每次关闭水阀之后，空气也被允许进入喷口或其他水压降低，喷口阀具有阻止回流的附加特征，所有这些都符合抗污染消防栓的要求。

摘要： A process for producing and fixing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizer and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizer can absorb radiation of a sensitizer wavelength which does not, in the absence of the sensitizer, cause decomposition of the superacid precursor to form the corresponding superacid. The secondary acid generator is capable of acid-catalyzed thermal decomposition by the first acid to form a secondary acid, and the image dye undergoes a color change upon contact with the secondary acid. The medium is imagewise exposed to radiation of the sensitizer wavelength, thereby causing the sensitizer, in exposed areas, to decompose superacid precursor with formation of the fist acid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The components of the acid-generating and color-change layers or phases are mixed so that in exposed areas, the secondary acid causes the image dye to change color. At least the non-exposed areas, there is reacted with the superacid precursor a reactive material which irreversibly destroys the superacid precursor, thus fixing the image.

摘要： Acid can be generated by exposing a mixture of a superacid precursor and a dye to actinic radiation of a first wavelength which does not, in the absence of the dye, cause decomposition of the superacid precursor to form the corresponding superacid, thereby causing absorption of the actinic radiation and decomposition of part of the superacid precursor, with formation of a protonated product derived from the dye, then irradiating the mixture with actinic radiation of a second wavelength, thereby causing decomposition of part of the remaining superacid precursor, with formation of unbuffered superacid. Preferably, following these irradiations, the imaging medium is heated while the superacid is admixed with a secondary acid generator capable of being thermally decomposed to form a second acid, the thermal decomposition of the secondary acid generator being catalyzed by the presence of the superacid. The acid generation process may be used for imaging by bringing the superacid or second acid into contact with an acid-sensitive material which changes color on contact with acid, or the superacid may be used to trigger polymerization, depolymerization or other reactions.

摘要： Acid can be generated by exposing a superacid precursor to actinic radiation effective to generate superacid from the superacid precursor and heating the superacid in admixture with a secondary acid generator capable of undergoing thermal decomposition to produce a secondary acid. The superacid catalyzes decomposition of the secondary acid generator, thus increasing the quantity of strong acid present in the medium. The resultant secondary acid can be used to effect a color change in an acid-sensitive material, so providing an imaging process.

摘要： A process for producing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizing dye and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizing dye has a unprotonated form and a protonated form, the protonated form having substantially greater substantial absorption in a first wavelength range than the unprotonated form. The superacid precursor is capable of being decomposed to produce superacid by radiation in a second wavelength range, but is not, in the absence of the sensitizing dye, capable of being decomposed by radiation in the first wavelength range. The secondary acid generator is capable of acid-catalyzed thermal decomposition by unbuffered superacid to form a second acid. While at least part of the sensitizing dye is protonated, the medium is imagewise exposed to radiation in the first wavelength range, thereby causing, in the exposed areas of the acid-generating layer, the formation of unbuffered superacid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the second acid. The components of the acid-generating and color-change layers or phases are then mixed so that the second acid causes a change in color of the image dye, and sufficient base is introduced into the unexposed areas to restore the sensitizing dye to its unprotonated form.

摘要： A process for generation of acid uses a medium comprising a first acid-generating component capable of generating a first acid, and a secondary acid generator, this secondary acid generator being capable of thermal decomposition to form a secondary acid, the thermal decomposition of the secondary acid generator being catalyzed by the first acid. At least part of the medium is exposed to so as to cause formation of the first acid from the first acid-generating component; and the medium is then heated to cause, in the exposed part of the medium, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The secondary acid generator has a first site bearing a first leaving group and a second site bearing a second leaving group, the first leaving group being capable of protonation by the first acid, with expulsion of the first leaving group, followed by loss of a proton from the secondary acid generator to form an unstable intermediate, which then fragments with loss of the second leaving group, accompanied by either (a) loss of a second proton; or (b) addition of a proton-containing nucleophile, followed by loss of a proton, the second leaving group, in combination with a proton, forming the secondary acid. Preferred variants of the process are of the types described in U.S. Pat. Nos. 5,286,612; 5,334,489; 5,395,736; 5,441,850 and 5,453,345.
