摘要:
A cosmetically acceptable medium containing a component and an aqueous gel that includes water and: (a) a cationic polymer; (b) an anionic surfactant having from 8 to 22 carbon atoms, where the amount of the anionic surfactant is less than the amount of the cationic polymer; (c) an amphoteric surfactant, where the amount of the amphoteric surfactant is less than the amount of the cationic polymer; and (d) optionally a long chain amine oxide, where the amount of said long chain amine oxide is less than the amount of the cationic polymer. The component is selected from a cationic surfactant, a conditioning agent, a synthetic amphoteric polymer, a synthetic ampholytic polymer, a synthetic non-ionic polymer, an amino acid, a protein, an oxidizing agent, a hair dye, dyes, pigments, a fragrance, one or more vitamins, and mixtures thereof. The cosmetically acceptable medium can be used to treat keratin-based substrates.
摘要:
A method and an apparatus for separation and separate flow of gas and liquid in a flow system, e.g. a tube system, wherein there is flowing a liquid or a liquid mixture containing gas or giving off gas as a function of time and/or variable pressure. The gas (10, 11) is permitted to separate continuously from the liquid phase (9) and thereby establish and maintain a pneumatic system in pressure equilibrium with the hydraulic system, by separation of the two phases by means of at least one permeable blocking layer (7), e.g. of textile material, which is so arranged along the length of the flow system that the heaviest medium (9) at all times will be located on that side of the blocking layer configuration (7) conditioned by gravimetrical forces, at the same time as the layer, or a configuration of layers, allows a change of the available cross-section for the essentially two phases (8, 9) along the length of the flow system, in order to compensate for variations in quantity between the phases.
摘要:
A device, which is displaceable by pumping through a conduit and which is utilized to obtain the drive of tools introduced by pumping into a producing petroleum well, generally comprising an elastic sleeve externally provided with small plates which make contact with the inner wall of the conduit; the plates are annularly distributed around the elastic sleeve. Adjacent plates and the interlocking means, which provides a slight sliding play, reduce the hydraulic leakages between the plates when the latter are in a spaced position.

Methods of remotely facilitating the transition between flooding and hydrotesting a subsea pipeline include a control unit of a subsea valve actuation system closing off fluid flow out of the pipeline at the receiving end thereof based at least partially upon one or more signals emitted by at least one intelligent pig that has passed through the pipeline during flooding and without the involvement of an external source at the surface, or a UV, at the pig receiving end of the pipeline.
摘要:
A retrieval device (6) is disclosed for retrieving spherically shaped cleansing bodies cyclically circulated through the cooling system of a tubular heat exchanger (2). The device has a cylindrical housing (8) subdivided into two chambers (12,13) by a filter plate (11). The end (21) of a drain tube (14) reaches into a chamber (12), while ends (19,20) of a feed tube (5), a discharge tube (7) and a rinse tube (17), respectively, into a second chamber (13). Two exteriorly driven shafts (23,24) are centrally mounted in the housing (8) and each has adjustable valve plates (32,34 and 33,35) mounted to seal against the upper and lower tube ends (19,21 and 20,22). The device (6) has three operating modes which are set by rotating the shafts to only two operational positions. In the discharging mode only the two lower tube ends (20,22) are opened and the cleansing bodies are flushed from the lower chamber (13) into the cooling water conduit (1); in the retrieval mode, only the upper tube ends (19,21) are opened, and bodies are trapped in the lower chamber (13) while water continues to flow through filter plate (11) into upper chamber (2), from where it is discharged; in the inspection mode all four tube ends (19,22) are closed, permitting the contents of the device to be inspected.
摘要:
Apparatus for separating a stream of flowing liquid in a conduit into segments separated by gas bubbles of a known or at least controllable size includes a chamber communicating with the interior of the conduit and a duct of smaller cross section than the chamber, which projects into the chamber and is connectable to a source of gas under pressure: the size of the gas chamber, can be adjusted to change the rate at which the gas bubbles are injected and thus vary the length of the liquid segments.
摘要:
In a system for loading a liquid into a tank truck by means of a pipeline, a pig is used for pushing product through the line toward the truck. This pig is stored at the source end of the line and is caused to move through the line first toward the truck end, and then back to its storage location at the source end, all in response to the operation of a ''''pig start'''' pushbutton.
