    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.

    Abstract: An apparatus for disposing liquid effluent which has been separated from a fluid system includes a compressor for supplying a compressed fluid to the fluid system. An engine for driving the compressor has an exhaust system which vents an exhaust fluid to an atmosphere external to the fluid system. An aftercooler is flow connected to an outlet of the compressor. A separating means for removing liquid effluent from the compressed fluid is flow connected to the aftercooler. The separating means has a conduit through which the separated liquid effluent flows. A reservoir for collecting the liquid effluent is flow connected in fluid receiving relation to the conduit of the separating means and flow connected in fluid supplying relation to the exhaust system of the engine. During operation, the collected liquid effluent flows from the reservoir into the exhaust system, whereupon entry therein, the exhaust fluid vaporizes the liquid effluent.

    Abstract: There is provided a dredge vehicle supporting a dredge assembly for collecting ore particles from the ocean floor. The dredge assembly includes several nozzles extending forwardly of the supports for the vehicle, pump means for developing a suction flow into and through the nozzles and a screen to separate the ore particles from most of the water before feeding the ore into, e.g., an airlift system leading to a surface vessel. Preferably, an intake of clear water from above the vehicle is used to carry the ore to and up the airlift system.Advantageously, the water flows straight through the system and exhausts from the rear of the vehicle, and mud is cleared from the ore before bringing the ore to the surface.

    Abstract: A liquid flow system which comprises means to screen long slender objects from a liquid flowing in a conduit. The screening means comprises a set of opposed, aligned, undulating surfaces, each having axes of curvature extending in at least two directions. In another embodiment there is a primary set of corrugated surfaces, with axes extending in a single direction transverse to the direction of fluid flow, and a secondary set of corrugated surfaces mounted on the primary set with axes transverse to the direction of fluid flow and transverse to the axes of the primary set. The undulating surfaces are preferably formed as primary corrugated plates with secondary corrugated plates transversely mounted on each primary corrugated plate. The primary corrugated plates can be moved apart to permit the removal of trapped debris. Dimpled plates can alternatively be us

    Abstract: An embodiment of the invention comprises a pneumatically operated regulating valve having porting therein for venting therethrough the pilot-signal, pressured fluid which is normally conducted to the front clutch internal control valve of a power transmission. The regulating valve is in communication with a source of pneumatic pressures. When the pneumatic pressure of the source is elevated, it causes the regulating valve to vent the pilot-signal, pressured fluid. Resultantly, the transmission is prevented from going into its lock-up mode and, instead, remains in its converter mode. The method sets forth the steps of modifying a standard transmission, without altering the latter's as-built configuration and arrangement, to incorporate the novel controlling means.
