In order to inhibit titanium oxide from settling down over a long period of time and secure a leveling property of a coating fluid including an ink composition, provided is a coating fluid for a fluid applicator, comprising at least titanium oxide, a resin and an organic solvent, wherein an additive comprising an N-acylamino acid derivative whose fundamental frame is at least one selected from N-acylamino acid amides and N-acylamino acid esters is added in an amount of 0.6 to 4.5% by weight base...

A diffusion-tight fluid conduit for hydrocarbon-containing fluids has a corrugated pipe of corrosion-resistant metal with a corrugated inner side and a corrugated outer side, wherein the outer side is exposed. An inner pipe of plastic material is arranged inside the corrugated pipe and has a smooth inner side and a smooth outer side. A first coupling member is seal-tightly connected by material bonding to a first end of the corrugated pipe.

Fluid--fluid contacting apparatus is provided with a structured packing comprising a series of packing elements fabricated from sheets of crimped material in such a way that the corrugations in each sheet extend obliquely with respect to the direction of bulk fluid flow through the apparatus. Each packing element is oriented with the sheets thereof in a plane which is angularly displaced with respect to the sheets of neighboring elements. A mechanism is provided at or in the vicinity of the inte...

A novel apparatus and process, including a baffle, for contacting a first fluid with a second fluid of lower density than the first fluid in counter-current flow in a manner that increases the contacting efficiency.

The invention provides a fluid composition for a fluid coupling, which is excellent in viscosity stability and torque stability, and comprises a polyorganosiloxane base oil having a viscosity of 3,000-500,000 mm.sup.2 /sec at 25.degree. C. and at least one 5-membered heterocyclic compound incorporated in a proportion of 0.01-3.0 wt. % based on the total weight of the composition, said 5-membered heterocyclic compound being selected from the group consisting of thiadiazole derivatives and thiazol...

A fluid exchange apparatus for the transfer of fluids from a first containment area to a second containment area, including a total fluid reconciliation process, whereby the same amount of fluid transferred from the first containment area to the second containment area is replenished into the first containment area, or is replenished to a preset amount. The fluid exchanger includes an evacuation section having a vacuum pump therein, and a fill section. The fluid being vacated from the first cont...

Gas-liquid contact apparatus comprising a packed bed formed of at least two superimposed layers of fabricated packings including an upper layer of randomly dumped members comprising ribbed tubular elements and a lower layer of stacked packing elements.

A separator for separating fluids of different densities from a mixture thereof including means to define at least one mixture flow path (80-85) which is helical or otherwise extends along and round an axis, and including a plurality of outlets (73b) from the flow path for the lighter fluid, such outlets being spaced apart along the flowpath and leading from a radially innermost part of the cross section of the flow path.

This disclosure relates to packing elements for fluid-fluid contact apparatus of the packed tower type. The packing elements comprise open-ended tubular members of any desired cross-sectional configuration having a maximum transverse dimension or diameter greater than its width in the axial direction, and having one or more protuberances or ribs extending inwardly from the inside wall of the member. Additionally, the overall length of the packing element is at least as great as the diameter of t...
