Abstract: A data resource specific to a pipe coupling centrally positioned within the coupling, intermediate the coupling ends. Multiple couplings are employed to connect together a string of well pipe. The data resource is adapted to be deployed at the coupling center in the space formed between the abutting ends of pipe made up into the coupling. The data resource provides information regarding the physical characteristics and locations of the coupling, the attached string pipe or the environment within which the coupling is disposed. The data resource may be a read-only component or it may be a readable and writeable component. The resource communicates with an instrument movable through the pipe and coupling. The data resource may be removably positioned at the center of the coupling or it may be permanently cemented in place. The data resource may take on the form of an annular ring with a crushable structure and suitable recesses for holding a data resource module.

Abstract: Composite pump components, such as a connecting rod comprising an elongate body having a core portion made up of concentric laminations or layers, the layers having elements the majority of which extend longitudinally with respect to the connecting rod and that are supported in a polymeric matrix, the layers being bonded together.

Abstract: A fault detection circuit in a boiler-water level system includes a dual-frequency signal generator which develops two AC components with no associated DC component. The two frequencies are mixed and sent through an impedance matching circuit to match the impedance of the signal generating portion of the system with the impedance of the boiler water under measurement. The impedance-matched signal is then directed to two legs, one leg directed through one of a plurality of electrode probes and then to a first filter circuit, and the other leg is directed a second set of filters. In combination, the filters pass either the higher or the lower of the two frequencies to determine an open or short condition in the level sensing circuitry, as well as a steam vs. water condition.

Abstract: A radiator system for mounting on the engine hood of an automobile having a rear engine comprising a generally panel-type radiator, a support for holding the radiator in a generally horizontal disposition and for securing the radiator to the engine hood, an inlet conduit for transferring heated engine coolant from the engine into the radiator, and an outlet conduit for transferring cooled engine coolant from the radiator to the engine.

Abstract: A stabilized ammonium polysulfide solution comprising an aqueous solution of ammonium polysulfide and a stabilizing amount of a water soluble, stabilizing compound that can be an azacyclic compound, a compound having the formula R--O--(C.sub.n H.sub.2n)NH.sub.2 or a compound having the formula (CH.sub.3).sub.2 NR.sub.1, the pH of the composition being from 7 to 14, the stabilized composition being useful in controlling the cyanide concentration in aqueous streams.

Abstract: A method of removing polymeric material from injection and producing wells in which an aqueous medium containing, chlorine dioxide or sodium chlorite is introduced into the well and maintained in contact with the polymeric material for a period of time sufficient to degrade the polymeric material to a desired degree and allow enhanced injectivity of polymer flooding medium into the injection well or enhanced production from a producing well.

Abstract: An improved process for the manufacture of a dihydric phenol such as hydroquinone wherein a dialkylbenzene is oxidized to a dihydroperoxide, the dihydroperoxide being extracted from the oxidate by a caustic solution, leaving an organic phase for recycle to the oxidizer, the improvement comprising decreasing the caustic concentration in the recycle organic phase and increasing the dihydroperoxide concentration of the recycle phase by washing the organic phase from the caustic extract with an aqueous phase removed from the oxidizer, separating the organic phase from the aqueous phase and subsequently introducing the organic phase to the oxidizer.

Abstract: An improved method for the acid-catalyzed rearrangement of a dialkylbenzene dihydroperoxide to a dihydric phenol which eliminates the formation of an emulsion during the subsequent separation and recovery of the dihydric phenol in a process which utilizes water, the method comprising the addition of the acid as a solution in a water soluble organic solvent, preferably a ketone, which is non-reactive with the acid.

Abstract: An improved process for recovering high purity resorcinol produced by the rearrangement of m-diisopropylbenzene dihydroperoxide in which the rearranged product mixture is neutralized, the neutralized mixture being filtered, the filtrate being admixed with toluene, the acetone being removed by distillation and the acetone-free rearranged product/toluene mixture being steam distilled to provide an aqueous resorcinol containing phase from which the resorcinol is recovered.

Abstract: Separation of diisopropylbenzene dihydroperoxide from a diisopropylbenzene oxidation reaction mixture by treating the reaction mixture with concentrated alkali metal hydroxide and recovering the alkali metal salt of diisopropylbenzene dihydroperoxide in high purity and good yield, and subsequently converting the salt to diisopropylbenzene dihydroperoxide.

Abstract: Dihydric phenols produced by rearrangement of p-dialkylbenzene hydroperoxides are recovered from the rearrangement effluent by distilling byproduct ketone in a distillation tower from a mixture of the rearrangement effluent with benzene and dihydric phenol-containing aqueous feed and extracting impurities and aromatic byproducts with benzene. Benzene containing dissolved impurities and aromatic byproducts, and water containing the dihydric phenol are removed from the bottom of the distillation tower and separated in an extractor column, the dihydric phenol is recovered from its aqueous solution by crystallization and the mother liquor from the crystallization step is recycled to the distillation tower.
