Abstract: Magnetizable adsorbent particles suitable for use in a magnetically stabilized fluidized bed and with a smaller particle size than conventionally formed composite adsorbents are prepared by introducing magnetizable particles such as magnetite or iron into a reaction mixture for forming a zeolite having adsorbent properties, such as zeolite Y. The zeolite is formed as a coating on the magnetizable particle.

Abstract: This invention relates to a fluidized bed process. More particularly, the present invention is a process for operating a magnetically stabilized fluidized bed by using a magnetizable fluid to fluidize solid particulate nonmagnetizable fluidizable particles. The operating conditions are such that there is substantially no random motion or time-varying pressure fluctuation as measured at a point within the bed.

Abstract: A process for the recovery of a fluid from a porous formation whereby fingering effects are controlled by applied magnetic field. The process comprises injecting a displacement fluid and ferrofluid, or a ferrofluid-containing displacement fluid, in an effective amount to displace fluid from the formation, applying a magnetic field containing a gradient of field intensity across said formation, driving the displaced fluid through the formation and recovering the displaced first fluid.

Abstract: A slurry is formed of particles of a non-magnetic oxide of iron (.alpha.-Fe.sub.2 O.sub.3), an oil carrier liquid and a surfactant. The slurry is then processed in an attrition mill where kinetic energy is applied to the slurry to convert the .alpha.-Fe.sub.2 O.sub.3 particles to magnetic iron oxide particles to form an oil-based ferrofluid. In order to increase the saturation magnetization of the resulting ferrofluid, a beneficial agent is brought into contact with the slurry during processing in the attrition mill. The beneficial agent can be a magnetic material, such as elemental iron, or can be water. A ferrofluid can also be formed by creating a powder of surfactant-coated magnetic particles and using an attrition mill to coat the particles with a second surfactant and suspend the coated particles in a carrier liquid.

Abstract: A system that will indicate tire inflation. A two-dimensional array of sensors is used to determine the distribution of contact forces over the footprint of a pneumatic tire. A neural network may be employed to classify the patterns of force sensed in this manner, and to closely estimate the actual tire inflation pressure.

Abstract: This invention relates to a process for magnetically stabilizing the operation of contactor columns containing immiscible fluids passing in dispersed countercurrent flow. The process operates by including, in an appropriate fluid phase, a magnetizable component in an amount which does not substantially change the nature of the liquid in that phase and, further, imposing upon at least a portion of the column containing dispersed phases, a magnetic field sufficient to result in substantially diminished radial mixing of the phase containing the magnetizable substance and diminished coalescence of the dispersed phase. The phase containing the magnetizable component passes through the stabilized zone in substantial plug flow.

Abstract: A fluidized bed process is disclosed which comprises subjecting a bed comprised of solid particulate magnetizable, fluidizable material within an external force field wherein at least a portion of the bed containing said solid particulate magnetizable and fluidizable material and fluidizing fluid are subjected to a nontime varying and substantially uniform applied magnetic field having a substantial component along the direction of the external force field such that said solid particulate magnetizable and fluidizable material has a component of magnetization along the direction of the external force field and wherein at least a portion of said bed containing the solid particulate magnetizable and fluidizable material is fluidized by a flow of fluid opposing said external force field at a superficial fluid velocity ranging between:(a) more than the normal minimum fluidization superficial fluid velocity required to fluidize said bed in the absence of said applied magnetic field; and,(b) less than the superficial fluid velocity required to cause time-varying fluctuations of pressure difference through said stably fluidized bed portion during continuous fluidization in the presence of said applied magnetic field. The strength of the magnetic field and its deviation from a vertical orientation are maintained so as to prevent and/or suppress the formation of bubbles in the fluidized media at a given fluid flow rate and with a selected fluidized particles makeup.Fluid throughput rates which are up to 10 to 20 or more times the flow rate of the fluidized bed at incipient fluidization in the absence of the applied magnetic field are achieved, concomitant with the substantial absence of bubbles. The magnetically stabilized fluidized bed has the appearance of an expanded fixed bed with no gross solids circulation and very little or no gas bypassing.
