摘要： A process for preparation of a 2,3 or 4-oxo-benzaldehyde or ketone compound by reaction of a 2,3 or 4-hydroxy benzaldehyde or ketone with an ortho, meta or parabromo or chloralkylphenoxy compound comprises reaction of the bromo or chloroalkylphenoxy compound with potassium iodide to form an iodo compound in situ; then, reaction of the resulting product with a 2, 3 or 4-hydroxybenzaldehyde or ketone in the presence of alkylpyridine and a dipolar aprotic solvent. The resulting compounds are useful for formation of photographic color couplers for use in photographic materials.

摘要： Suction apparatus, particularly designed for handling liquid and semi-liquid materials in an industrial context, comprises a suction tank provided with simultaneously operable exhauster and discharge pumps each driven by a common compressed air source. The operational parameters of the pumps and the dimensions of conduits are such that during operation to raise a given liquid or semi-liquid the mean depression in the tank falls at least intermittently to a value at which the discharge pump can raise the contents of the tank. The arrangement enables continuous operation or suction to reclaim or handle liquid or semi-liquid material.

摘要： A process for obtaining highly stable color photographic images utilizes a silver halide photographic element comprising an essentially colorless, immobile compound which is capable of complexing with ferrous ions to form a dye. The complexing compound contains a complexing moiety which is represented by the formula: ##STR1## wherein m is zero or a positive integer 1 to 3, n and p are independently 0 or 1 and represents a single or double bond. Z is R.sup.1 --N.dbd., O.dbd., S.dbd., R.sup.1 --P.dbd., (R.sup.1).sub.2 P-- or (R.sup.1).sub.3 P.dbd., and when Z is (R.sup.1).sub.2 P--, n is 1, otherwise n is 0. R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are independently hydrogen, amino, hydroxy, mercapto, alkoxy, alkyl, aryl or a heterocyclic moiety. When R.sup.6 is so defined, p is 1 and is a single bond. If m is 0, R.sup.1 and R.sup.2, R.sup.2 and R.sup.3, and R.sup.3 and R.sup.4 taken together can independently represent the carbon and heteroatoms necessary to complete a substituted or unsubstituted carbocyclic or heterocyclic nucleus, or if m is 1 to 3, R.sup.1 and R.sup.2, R.sup.5 and R.sup.6, and R.sup.3 and R.sup.4 can independently represent the carbon and heteroatoms necessary to complete a substituted or unsubstituted heterocyclic nucleus. When R.sup.5 and R.sup.6 are so defined, p is 0 when is a double bond, and p is 1 when is a single bond.

摘要： An engine assembly that is powered by high pressure vapor from a volatile liquid that has a boiling point substantially below the minimum ambient temperature in the geographical location in which the engine assembly will be used. Heat for volatilizing the liquid may be withdrawn from the ground, naturally occurring sources of water, as well as from sunlight and waste heat from industrial installations. Although the engine assembly is capable of being used to produce power for any desired purpose, it is particularly adapted for use in pumping water from a well, with the pumped water not only being used for irrigation purposes and the like, but also to effect an initial cooling of the low pressure vapor discharged from the engine assembly prior to the vapor being further cooled and pressurized to return to the liquid state whereupon it is heated and recycled through the engine assembly. The volatile liquid may be a suitable one of the various Freons that are commercially available, such as Freon 22, liquid carbon dioxide, ammonia, or the like. Although the engine assembly will preferably operate on naturally occurring heat, it is adapted to operate on heat from a conventional fuel such as Diesel oil, wood, sawdust and the like when the occasion so requires. Water may also be used as a source of vapor providing the source of heat is of sufficient magnitude to convert the water to superheated steam.
摘要翻译：发动机组件由来自挥发性液体的高压蒸气提供动力，该挥发性液体的沸点基本上低于使用发动机组件的地理位置的最低环境温度。用于挥发液体的热量可以从地面，天然存在的水源以及来自工业设备的阳光和废热中排出。虽然发动机组件能够用于产生用于任何所需目的的动力，但是特别适用于泵送来自井的水，其中泵送的水不仅用于灌溉用途等，而且还用于实现在蒸汽被进一步冷却和加压之前，从发动机组件排出的低压蒸气的初始冷却返回到液体状态，从而将其通过发动机组件被加热和再循环。挥发性液体可以是可商购的各种氟利昂中的合适的一种，例如氟利昂22，液体二氧化碳，氨等。尽管发动机组件优选地在自然发生的热量下操作，但是当需要时，它适于在诸如柴油，木材，锯屑等常规燃料的热量下操作。水也可以用作蒸气源，提供足够大的热量将水转化成过热蒸汽。
