Abstract: Articles are degreased by being lowered into a zone of vapour originating from a pool of boiling solvent. The vapour condenses on the articles, dissolving oil and other impurities, and the impure solvent is allowed to flow into the pool of boiling solvent. The articles are now dipped into a pool of comparatively cold solvent. Finally, the articles are lifted up into the vapour zone, and the pure solvent formed by condensation on the articles is allowed to flow into the pool of comparatively cold solvent.

Abstract translation: 制品通过下降到源自沸腾溶剂池的蒸气区域而脱脂。 蒸汽在物品上冷凝，溶解油和其他杂质，并使不纯的溶剂流入沸腾溶剂池中。 这些物品现在浸入比较冷的溶剂池中。 最后，将物品提升到蒸气区，并将物品上的冷凝形成的纯溶剂流入比较冷的溶剂池中。
