Abstract: A solvent dewaxing process for removing wax from intermediate grade waxy petroleum distillate oils wherein a waxy oil stock, prediluted with 0-2 volumes dewaxing solvent is heated to a temperature in the range of about 110 to 130.degree. F for melting all wax therein; wherein the heated waxy oil stock/solvent mixture is cooled to about 5.degree. F above the depressed cloud point and is diluted with 1-5 volumes dewaxing solvent having a temperature 25.degree.-40.degree. F below the depressed cloud point for forming a wax/oil/solvent mixture having a temperature 5.degree.-15.degree. F below the depressed cloud point, and wherein the wax/oil/solvent mixture is further cooled at 1.degree.-8.degree. F/min. to a selected separation temperature in the range of 0 to -40.degree. F for precipitating additional wax. Precipitated wax is removed at the separation temperature to produce a wax free oil/solvent mixture which is subsequently fractionated to yield a dewaxed oil suitable for use in lubricating oils.

Abstract: A process for deoiling and dewatering refinery sludges in which sludges, optionally mixed with a diluent oil such as recycle oil recovered in the process, are contacted in a heating zone with steam or superheated steam to effect separation of the sludges into dry, oil-free, free-flowing solids and an oil-water vapor phase which on condensation yields a mixture of oil and water. The oil recovered from this mixture is suitable for a variety of purposes such as for cracking stock, etc. and the water recovered exhibits a reduced Chemical Oxygen Demand. The dry, free flowing solids recovered from the heating zone are useful for a wide variety of applications, such as for land fill.

Abstract: This is a process and apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular. Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom.

Abstract: A pivoted pointer or stylus is mounted for actuation by reciprocatory plunger action. It has a stop associated with the plunger to hold the stylus locked in a neutral position until the plunger is actuated. The stylus has a cam action surface for cooperating with another part of the stop after the stop has moved to release the stylus. The cam action causes pivotal movement of the stylus to indicate an event.

Abstract: Disclosed is a controlled two stage process for converting 1-olefins to 1,2-diacetoxyalkanes. In the first stage, the olefins are oxidized to peroxides by preaerating the olefin with oxygen until the measured peroxide value has reached its maximum, then decreasing this value by 20 to 40%. In the second stage, the peroxides are decomposed by adding acetic acid and heating to a temperature of 120.degree. C. in the absence of catalyst.
