A coating for sensor transducers that transmit a signal to&#x2014;and/or receive a signal from&#x2014;a fluid, either liquid or gas, in contact with the transducer. In particular the coating minimizes or eliminates fouling of the transducer surface by the fluid, reducing the need for transducer maintenance, while not interfering with the transducer's ability to send and/or receive signals.

Antifouling coating for sensor transducers used for monitoring fluid properties

The present invention relates to methods of using an aqueous composition or dispersion containing a water-soluble or water-dispersible synthetic polymer, and compositions formed thereof. The aqueous composition or dispersion is added to agricultural spray compositions, ink compositions, deicing or anti-icing compositions, latex paint and coating compositions, cleaner compositions, adhesives, fire-extinguishing chemical compositions, hydro-metallurgy/electro-winning compositions, compositions having organosilanes, personal care compositions, water-based hydraulic compositions, dust control compositions, and textile finish compositions, to impart properties including aerosol control, spatter control, shear stability, rheology control, transfer efficiency, oil/water reduction, sling control, emollient performance, film forming capability, surface activity, encapsulent ability, lubricity, thickening, and anti-wear capability, to the resultant composition formed thereof.

An electrorheological fluid is prepared from a hydrophobic liquid medium and a dispersed particulate phase of (i) a polar solid material which is capable of exhibiting electrorheological activity in the presence of a low molecular weight polar material and (ii) a non-cellulosic polymeric material having a solubility parameter of about 15 to about 50 (MPa).sup.1/2 and exhibiting substantially no electrorheological activity in the absence of a low molecular weight polar material. The fluid optionally contains a low molecular weight polar activator. The fluid has good electrorheological performance over a broad temperature range.

Electrorheological fluids containing particles of a polar solid material

The present invention relates to a curable composition comprising:

Curable aminoplast compositions and catalysts for curing same

The present invention relates to an improved process for beneficiating an ore containing sulfide materials with selective rejection of pyrite, pyrrhotite and other minerals and gangue. In particular, the process is useful for beneficiating ores and recovering metals such as copper, lead, zinc, etc., from said ores. In one embodiment the process comprises the steps of:

Ore flotation process and use of phosphorus containing sulfo compounds
