    摘要: There is disclosed a process for treating a clay mineral thereby to change its rheological properties when in aqueous suspension such that the fluidity of the aqueous suspension at a given temperature and percentage by weight of completely deflocculated clay mineral solids in the suspension is increased, which process comprises the steps of mixing with the clay mineral in a plastic state a minor proportion by weight of a water-soluble organic compound having a plurality of basic groups and a number average molecular weight not greater than 1000, and subsequently or simultaneously subjecting the mixture to mechanical working under conditions such that from 25 to 1000 KJ of energy per Kg of dry clay mineral are dissipated in the mixture.

    摘要: Optical article having a substrate with first and second surfaces and with a conductive antireflection coating disposed on the first surface. The conductive antireflection coating is comprised of at least one layer of a low index material carried by said first surface and a thin transparent conducting layer of a material having a high index of refraction carried by the layer of material having a low index of refraction. The conducting layer provides an exposed surface to which the direct electrical contact can be made. The conducting layer has an optical thickness ranging from 1.0 to 30.0 nanometers. The layer of material having a low index of refraction has its design thickness reduced to compensate for the thickness of the conducting layer whereby the conducting layer does not seriously degrade the optical performance of the coating over that which could be obtained without the use of the conducting layer.

    摘要: A circuit for controlling a valve assembly in applications where electrical isolation of the two control signal supply lines is required to prevent damage of control circuits caused by a reverse polarity feedback signal or other transient signal. The circuit includes a solenoid having a coil. The coil has a first end and a second end. The circuit also includes a first switching circuit electrically connected to the first and second ends of the coil to allow current to pass therethrough in a first direction to move a permanent magnet against a pushpin a first axial direction. The circuit further includes a second switching circuit electrically connected to the first and second ends of the coil to allow a current to pass therethrough in a second direction to move the permanent magnet away from the pushpin in a second axial direction. Further, when either switching circuit is allowing current to flow through the coil, it electrically isolates one negative control source from the other. The use of a pair of switching circuits electrically connected to the coil results in a relatively low voltage drop across the circuit.
