An oil supply apparatus for a vehicle includes: an oil pump that supplies oil in an oil pan that stores the oil circulating in an engine; an oil supply passageway that supplies the oil from the oil pump to a lubricating part and a hydraulic actuating part of the engine; and a bubble separating unit that is provided in the oil supply passageway and separates bubbles contained in the oil.

This disclosure concerns a method for removing gas and/or gas bubbles from a liquid medicament stored in a reservoir for an infusion pump device. The reservoir comprises a displacing member which is at least partly displaceable relative to the reservoir thereby enabling receiving mechanical oscillations in order to generate mechanical waves in the liquid medicament. The method comprises: providing the reservoir; and transmitting a mechanical oscillation to the displacing member of the reservoir thereby generating a mechanical wave in the liquid medicament for removing gas and/or gas bubbles from the liquid medicament.

A device for degassing liquids, in particular liquids used in dialysis, has a degassing unit that includes an ultrasonic unit. Liquids to be degassed are treated in the degassing unit by ultrasound from the ultrasonic unit. Degassed liquids are discharged from the degassing unit through a hollow channel in the ultrasonic unit, and are available for further use.

A semiconductor electrochemical plating (ECP) tool includes: a plating cell which receives an ECP solution therein; a support onto which a semiconductor substrate is selectively secured, the support being controllable to selectively dip the semiconductor substrate into ECP solution contained in the plating cell; a recirculation system including a reservoir that receives an overflow of ECP solution from the plating cell, the ECP solution being recirculated from the reservoir back to the plating cell; a bubble monitoring system that detects gas bubbles within the ECP solution; and a degassing system that inhibits at least one of gas bubble formation, nucleation and growth within the ECP solution, wherein the degassing system is controlled at least in part based upon gas bubble detection by the bubble monitoring system.

An apparatus for removing a gas in an immersion ultrasonic process is provided. The apparatus, in the form of an immersion ultrasonic transducer holder apparatus, has a body with a first end, a second end, a plurality of sides, and a hollow interior cavity portion. A holder portion with an exterior end and an interior end is formed through the first end, and holds one or more immersion ultrasonic transducers. A sloped inner face having a base end with a knife-edged perimeter is adjacent the interior end of the holder portion. The sloped inner face has an upward sloped surface extending from the base end to an evacuation end. One or more evacuation ports are formed through the first end, and adjacent the evacuation end. When the apparatus is used in the immersion ultrasonic process, the knife-edged perimeter, sloped inner face, and evacuation ports facilitate removal of the gas.

Methods and systems for treating a liquid material. A liquid is emplaced in a treatment zone: microwave energy and ultrasonic energy are collectively applied to the treatment zone to effect release of a gaseous material from the liquid material.

A reflux unit and a sewage treatment system are disclosed. The reflux unit includes an input section, a treatment section and an output section which are sequentially communicated. The treatment section is configured for deoxidizing a reflux substance input by the input section. The treatment section is at least partially located above an aeration port of an aeration device or the treatment section is attached to a surface of the aeration device.

The present invention relates to a method of adapting and manufacturing a separator system comprising multiple inclined separators for separation of respective substances or substances mixed in fluids from oil wells and adapting the separator system to a change in the substance or use with another oil well. The method involves determining percentage fraction of respective fluid phases in an oil from a specific oil well and at a specific time and estimating expected production rate from the specific oil well at a specific time to estimate the streaming capacity of each respective fluid phase through separators of the separator system. The method also involves arranging a plurality of interconnecting frameworks of pipes in parallel or serial depending on the estimate streaming capacity.

The system and method is directed to improved separation or clarification of solids from a solids-laden liquid, including the removal of low gravity solids. A liquid to be treated is introduced into the inlet of a solid-liquid separator modified to include one or more sources of vibrational energy. The liquid is directed through a conduit within the separator. This conduit can be configured into a tortuous flow path to assist in the separation of solids from the liquid, the tortuous path being interconnected between two separation towers. Vibrational energy and gas sparging is applied to the flow path. As solids fall out of solution, they are collected. The clarified liquid is also collected. A vacuum can be applied to the system to assist in moving the solid-liquid mixture through the system and to provide vacuum clarification. Electrocoagulation electrodes can also be employed.

The present disclosure provides methods for removing defects nanotube application solutions and providing low defect, highly uniform nanotube fabrics. In one aspect, a degassing process is performed on a suspension of nanotubes to remove air bubbles present in the solution. In another aspect, a continuous flow centrifugation (CFC) process is used to remove small scale defects from the solution. In another aspect, a depth filter is used to remove large scale defects from the solution. According to the present disclosure, these three methods can be used alone or combined to realize a low defect nanotube application solutions and fabrics.
