An oil-in-water-in-oil emulsion (O/W/O) comprising a first oil-in-water emulsion dispersed in a second oil, and a method of preparing the same. The O/W/O emulsion can be used as a drive fluid in an enhanced oil recovery process. The O/W/O emulsion of this invention may also be used as a lubricant, and has the beneficial property of being resistant to shear forces.

An oil cooling apparatus having at least two sides. Extending from a first side and integral therewith is a first scoop defining a first duct. Extending from a second side and integral therewith is a second scoop defining a second duct. Within the first and second ducts are oil coolers having fins which allow heat to be removed from the oil as air passes through the duct during operation of the, for instance, motorcycle. After moving through the first and second oil coolers, the oil is deposited...

An oil burner for oil wells in which the oil to be eliminated is admitted to a specially designed sprayer in which its mechanical atomization is brought about by the construction of said sprayer and its pneumatic atomization is effected by means of inputting gas or air under pressure, the atomized product being ignited by means of spark ignitors and the flame produced being protected by a cylindrical casing. Said casing is provided with a front spray ring which injects water into the flame so as...

Crude oils, lubricating oils or fuel oils have their flow point improved by adding to the crude oil, lubricating oil or fuel oil a minor proportion by weight of a polymer containing the repeating units: ##STR1## where x is an integer and y is 0 or an integer and wherein in the total polymer x+y is at least two.

An oil reservoir for an oil burner capable of ensuring oil-tightness between the oil reservoir and a partition with simple operation and structure and reducing a manufacturing cost. In the oil reservoir, a partition plate and a cover plate are provided with a plurality of spot welding portions and opposite to each other through an annular overlap formed therebetween. One of the partition plate and cover plate is formed at the overlap with an annular projection which is arranged in a manner to pr...

A shoe roll of a shoe press for use in a papermaking machine, the shoe roll including a blanket, or endless belt, which houses a shoe assembly that, in cooperation with an external backing roll, forms an extended nip proper. The shoe press includes an oil circulation piping system for removing the oil from the interior of the shoe roll and transferring the oil to an oil trap during the running of the machine, whereby the piping system also includes a suction fan connected thereto. The device is ...

Disclosed herein is an oil composition comprising the following components (A) and (B):(A) 15 to 70% by weight of diglycerides in which less than 15% by weight of the constitutive fatty acids are (3 type unsaturated fatty acids; and (B) 30 to 85% by weight of a triglyceride in which at least 15% by weight of the constitutive fatty acids are (3 type unsaturated fatty acids. The oil composition is good in flavor, hard to be colored, excellent in hydrolytic stability and resistance to oxidation, go...

An oil separator that removes oil from ventilation gases flowing between a crankcase and an intake manifold of an internal combustion engine. The oil separator includes a housing, a wall and a diaphragm. The housing has an inlet and an outlet. The wall is cooperative with the housing to define a path through which the gases flow between the inlet and the outlet. The wall is movably coupled to the housing to effect a change in the height of the path. The diaphragm has a movable portion coupled to...

The invention relates to an improved system for supplying filtered oil to wet brakes of the tractor without additional/auxiliary pump. The system comprises of a suitably sized connection provided on the drain line of the Hydraulic system, which supplies required quantity of filtered oil to the wet brakes through a passage with a line pressure of 2-3 kg/cm2. This positively ensures the oil supply and circulation of oil for heat removal from wet brakes. A hollow bush is so sized and located on the...

An oil cooler is contained in a radiator tank. It includes a connecting pipe having an enlarged diameter portion, a heat exchange part including elements and a communicating passage fluidically communicating the elements, and a pipe connector. The pipe connector has a first retaining portion seated on one side of a wall portion of the radiator tank to contain and fix at least a part of the enlarged diameter portion of the connecting pipe by caulking, and a second retaining portion inserted throu...
