Method and System of lubricating at least one moving part with a medium. The medium includes a dissolved mixture of lubricant and compressed gas. The amount of lubricant and compressed gas may be controlled in forming the dissolved mixture in response to input conditions. A user and/or external factors may be used to determine the input conditions. In response to the input conditions the amount of lubricant and compressed gas is delivered to the moving part that is housed in a pressurized chamber. The properties of the dissolved mixture can be adjusted, whereby the properties may include, but are not limited to, the following: viscosity, temperature, and thermal conductivity. This adjustment to the gas may be accomplished, for example, by releasing gas from the pressurized chamber in an amount to adjust the properties. In a further approach, lubricant may be scavenged from the pressurized chamber by returning surplus lubricant to its original source or other designated location.

An aircraft engine oil distribution system includes a system container, an oil reservoir disposed in the system container, the oil reservoir having a plurality of fins protruding from an inner-surface of a wall of the oil reservoir and extending into the oil reservoir, and a heat exchanger disposed in the system container. The heat exchanger includes a cooling fluid passage defined at least between the one or more walls of the system container and the sidewall of the oil reservoir, a matrix disposed in the cooling fluid passage in heat transfer relationship with the plurality of fins of the oil reservoirs.

An oil tank for an engine is provided with a separator that reduces the amount of entrained air in the oil tank. The separator includes a body with an outer wall, a divider wall, and an outlet. The divider wall is located between the outer wall and at least a first portion of the outlet. The divider wall is offset from a curved portion of the outer wall, which defines a flow channel through which the oil flows towards the outlet. The oil increases speed as travels around the divider wall. This movement keeps the oil with some and/or more entrained air closer to the outer wall. In contrast, the oil with less or no entrained air moves closer to the divider wall and may travel more directly to the outlet.

A hydraulic fracturing plan executable by a hydraulic fracturing system to hydraulically fracture a plurality of oil and gas wells.

This invention refers to a magnetic anti-scaling device that can be coupled around piping with fluid flow inside it, comprising an external tube; and a plurality of magnetic arrangements, wherein each magnetic arrangement is formed by a cylindric support and a plurality of magnets circumferentially positioned on the cylindric support: wherein the plurality of magnetic arrangements comprises a sequency of magnetic arrangements placed side by side, and likely to be longitudinally coupled around the piping in an axisymmetric arrangement, so as to form, at least, a concentration plan of magnetic field; and wherein a spacer and an absorber are positioned at each end of the axisymmetric arrangement, and the external tube surrounds the axisymmetric arrangement. The application of a high-density magnetic flow orthogonally to the speed of the fluid to be treated inhibits formation of scales at the internal wall of piping, thus reducing scaling at the equipment upstream.

A method and device for analyzing oils, technical service fluids and for the evaluation of the operating states of units, wherein a drop of test fluid to be examined is applied to a test medium which is allowed to penetrate the medium, and is evaluated after a preselected time by optically comparing a resulting image with the data of a plurality of reference images with respect to a plurality of test criteria. The test fluids to be examined can give information about the state of the test fluids. Fast and reliable detection, evaluation, and assessment are possible and reduce the influence of subjective assessment influences. A computer-assisted comparison of the data of the images with the data of the reference images is performed. Data of the images from the front, back-light, and possibly the UV back-light recording are associated with images for a test criterion that has the greatest correspondence.

The invention relates to a method for producing a cooling lubricant mixture (2) for cooling and lubricating a working region (8) of a forming apparatus (5) for forming semi-finished products, in particular semi-finished products and forming tools, in which the cooling lubricant mixture (2) is mixed from at least two liquids (27, 29), and in which at least one of the liquids (27, 29) is preheated prior to the mixing with the other of the liquids (27, 29), wherein, for the preheating of the at least one of the liquids (27, 29), thermal energy (44) inherent to a used cooling lubricant mixture (2A) is at least partially transmitted to the at least one of the liquids (27, 29).

A lubrication system includes an additive and a delivery system. During normal operational conditions, the lubricating oil circulating in the transmission system is collected and contained in a secondary oil reservoir to retain a quantity of the lubricating oil for use in an oil-out condition. When an oil-out condition is detected, the additive is injected and mixed with the collected lubricating oil in the secondary oil reservoir or dispersed directly into a power transmission gearbox housing to enhance the characteristics of the lubricating oil and increases the operational time period of the power transmission gearbox during an oil-out condition.
