A drive shaft rotatably supported in the housing and extending into said chamber for imparting mechanical energy to the rotor. The rotor having a generally hemi-spherically shaped form and provided with a series of openings. A fluid intake passage in said housing preferably arranged to be nearer the rotational axis of the rotor and a fluid exit passage preferably positioned radially outwardly of said rotor.

An apparatus comprising first and second fluid intakes, a pump, and a sample chamber, may be positioned in a borehole penetrating a subterranean formation. A method of use thereof may comprise drawing fluid from the subterranean formation and into the first and second fluid intakes using the pump, discharging into the borehole at least a portion of the fluid drawn into the second fluid intake, and selectively diverting at least a portion of the fluid drawn into the first fluid intake to the sample chamber.

A power plant extracts energy from a free flowing motive fluid by means of a turbine mounted on a gimbal. The shroud element of the fluid intake has external rudders, in conjunction with the gimbal mounting, enabling the enclosed turbine to instantaneously respond to changes in the direction of the free flowing motive fluid thus ensuring the face area of the intake is always physically orthogonal to the direction of the motive fluid streamlines. The shroud element may also be buoyant so as to optimally extract energy from an upper non-turbulent and higher velocity layer of the free flowing motive fluid. To function within an inherently unsteady source of energy, the preferred embodiment of the turbine is coupled to a DC generator which may further be coupled to a voltage and current regulating circuit which either charges a battery, performs electrolysis of water to produce hydrogen fuel, or is further coupled to a DC motor coupled to an AC generator. Alternatively an AC induction generator may be coupled to the turbine. Other mechanical, electrical, electronic, or electromechanical features may optionally be implemented to perform such tasks as adaptively locating the turbine in the maximum velocity flow, adapting internal vane and runner blade pitches for various flow rates and loads, keeping the intake free of obstructions, preventing loss of aquatic life, controlling and communicating the state of charge of the battery, or gauging and controlling the electrolysis process and communicating the fullness of the hydrogen gas output tanks.

A system extrapolates and interpolates patient fluid intake or output parameter values and associated cumulative values over variable time intervals from a reduced set of stored fluid parameter values affecting fluid cumulative volume computation or rate of fluid intake or output computation. The extrapolation and interpolation function accomodates drip (continuing) fluid volumes as well as supplemental (non-continuing e.g., bolus) fluid volumes. A patient medical parameter data processing system provides patient medical parameter data for trend indicative display covering a time period comprising user selectable patient parameter acquisition time intervals. The system includes an acquisition processor for receiving data identifying, for a continuing infusion, rate of volume of fluid infusion into a patient, a fluid type identifier and a start time and start date of said continuing infusion. The received data also identifies for a non-continuing infusion, a total volume of fluid infusion, a fluid type identifier and a time and date of the non-continuing infusion. A data processor determines, from the received data, a cumulative total volume infusion of a particular fluid into a particular patient for a particular user selectable patient parameter acquisition time interval.

A sensor for measuring a physical parameter of a fluid, in particular for measuring total air temperature, the sensor comprising: a fluid intake (1) fitted to a streamlined body (2); a duct provided in said streamlined body (2) to enable fluid flow, said duct communicating with said fluid intake; and a sensing element disposed inside said duct. The sensor is characterized in that it includes elements that give it improved measurement performance. In particular, the proposed air intake presents an inlet section which extends so as to define a sliding surface suitable for eliminating ice. The invention also provides an improved system for sucking in the boundary layer by using slots, and it also provides a ceramic sensing element that provides better thermal decoupling relative to the de-iced body.

Absorbent structures having controlled liquid intake, distribution and absorption properties include at least one substrate layer and a flexible absorbent binder formed on and bound to the substrate at selected locations. The flexible absorbent binder is selectively formed so as to provide flow channels, regions of higher and lower fluid intake and absorption, dams for preventing fluid leakage, and other desirable features. The absorbent structures are useful in personal care absorbent articles such as sanitary napkins, diapers, training pants, adult incontinence garments and the like.

Methods and apparatus for generating a small, maneuverable stream of filtered fluid without benefit of a pump or electrical power are disclosed. According to one aspect of the present invention, a spray nozzle apparatus for dispensing a maneuverable stream of fluid, that originates from a fluid source at a first pressure includes an adapter assembly, a nozzle subassembly, and a flexible tubing. The adapter assembly is mechanically coupled to the fluid source, and is arranged to allow the fluid to flow from the fluid source through the adapter assembly. The nozzle subassembly dispenses the fluid at a second pressure, and includes a fluid intake end and a fluid dispensing end. The fluid dispensing end allows the fluid to flow therethrough in a small, stream-like configuration at the second pressure, and is in fluid communication with the adapter assembly. The flexible tubing allows the fluid to flow through, and is coupled to the fluid intake end of the nozzle subassembly. In one embodiment, the spray nozzle apparatus includes a filter that is in fluid communication with the flexible tubing and the adapter assembly.

Disclosed is an applicator (1) for applying fluid to a substrate, comprising valve mechanisms (21) which are arranged in a row and are each equipped with an application valve nozzle (31), and a distributing fluid chamber (11) that has a fluid intake duct (110). A cleaning valve mechanism (21) which is incorporated into the row of application valve mechanisms (21) and is fitted with a cleaning valve nozzle (30) is associated with the fluid intake duct (110). A flow path (100) for cleaning the fluid chamber (11) is formed between the fluid intake duct (110) and the cleaning valve mechanism (20) in the distributing fluid chamber (11), said flow path (100) being effective when the cleaning valve nozzle (30) is open. Also disclosed is a method for cleaning said applicator (1). In said method, pressurized cleaning fluid is applied to the distributing fluid chamber (11), the application valve mechanisms (21) are kept closed while the cleaning valve nozzle (30) is opened, and the cleaning valve nozzle (30) is then closed while the application valve mechanisms are opened when the pressurized cleaning fluid is applied to the distributing fluid chamber (11). A valve mechanism (2) of the applicator (1) encompasses a detachably mounted nozzle diaphragm (3, 4) which unblocks a valve piston (51) in the removed state. The valve mechanism (2) further encompasses a straight fluid duct that remains free of flow corners.

This invention related to the geophysics, in particular, to geophysical methods of well survey, and can be applied for removal of wellbore liquid that fill the well, during the well logging process. This invention characterizes a filter for solid particles; which can be mounted at the suction side of submersible motor-driven pumps.

A well filter for submersible motor-driven pump comprising an elongated housing in which a cylindrical filtering element is installed. At one end of the filtering element, a fixture for fastening the filter housing to the pump is mounted; at the other end, there is at least one fluid intake port. A shape-deformable sealing element is installed on the housing outer surface.

The rigid structure of the sealing element creates problems with lowering the strainer to the well and may cause the damage of the said strainer. This damage creates leakage in the top part of the strainer. The way of resolving the engineering issue is development of a new design of the wellbore filter. The implementation of a new design of a wellbore filter makes the service life of submersible motor-driven pump longer.
