Abstract: ABSTRACT OF THE DISCLOSURE         Anti-caking agent is thoroughly distributed upon particulate hygroscopic materials, e.g., particulate inorganic salts such as potassium chloride and sodium chloride, by contacting an agitated stream of the par-ticulate material with an aqueous dispersion of anticaking agent and then passing the treated material through a fluid bed of the treated particulate materiel.  The pretreated particulate hygroscopic material is typically warm, i.e., has a temperature above 25°C., and is cooled in the fluid bed which is fluidized with dehumidified, fluidizing gas having a temperature lower than the treated particulate hygroscopic material entering the bed.          Cooled particulate hygroscopic material having a coating of anticaking agent distributed substantially uniformly over the surface of the particles and having a water content substantially the same as the pretreated warm particulate material is removed from the fluid bed.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to an active magnetic suspension device of a rotor placed in a sealed enclosure. Each active radial bearing comprises a stator composed of electromagnetic windings associated with a magnetic yoke which has end pole pieces placed at a short distance from the annular armature mounted on the rotor, the electromagnetic windings being arranged outside the sealed enclosure. Each stator magnetic yoke of luminary material is extended at the level of the end pole pieces by a terminal portion of non-laminar material, of small thickness, which constitutes directly a portion of the wall of the sealed enclosure and is attached by welding to the non-magnetic sealed wall portions which are not situated facing the annular armature.

Abstract: ABSTRACT     In a method of making a solid polycrystaliine ceramic, that is a precursor conductor for the hydronium ion (HO3+), feed compounds, which in the preferred embodiment are alkalies in the ratio of 60 wt% Na2CO3 and 40 wt% K2CO3, are mixed with 3  wt%  MgCO3  and  the  balance  Al2O3,  at  the  atomic  scale whereupon a preferred,  intermediate,  crystalline powder  is achieved with a chemical formula;              (Na0?6K0?4)2O (3 W/o MgO) .beta./.beta."-Al2O3 yielding an ?(.beta.) of approximately 0.37 where;                       and .beta. and  .beta." are the polymorphs of alumina.  This powder can be compressed and sintered, for a very short period of time, so the value of ?(.beta.) does not migrate significantly, yet the surface energy levels of the polycrystals are relieved and a solid  polycrystalline  ceramic, of any predetermined  shape, with the above formula is created.   It is shown herein that this  preferred  solid has  a conductivity greater than  10-1 (ohm)-1 (cm)-1 at 300°C.; 10-4 (ohm)-1 (cm)-1 at room tempera-ture;  that  the  conductivity  is  discontinuous  at  selected values of ?(.beta.) vis a vis temperature; and, how to select ?(.beta.).  Mixing at the atomic scale of the feed compounds may take place either by dissolving the feed compounds in water then  freeze  drying,  or  spray  drying  in  a  spray  dryer; thereafter, calcine and drive off any H20 residual.

Abstract: Heat Exchanger Abstract A heat exchanger having a plurality of longitudinally-extending tubes disposed within a shell includes an elastomeric end plate and means for compressing the elastomeric end plate and expanding the plate in the longitudinal direction and internal vibration-damping baffle plates.         Conventional metal heat exchangers of brazed construction are prone to cracking and failure.  More recently, heat exchangers having an end wall assembly comprising an elastic medium disposed between movable pressure plates has been proposed.  Among other problems, the movable pressure plates are required to have clearance holes for the free passage of tubes therethrough and are consequently severely limited to the number and density of tubes that may be accommodated in a heat exchanger of such a design.         The present invention avoids the problems of the prior art by providing an end wall assembly for a heat exchanger wherein an elastomeric end plate is mounted under compression in only a direction transverse to the tubes passing through the plate.  The elastomeric end plate is not restrained in a longitudinal direction with respect to the tubes and as a result of the transversely-applied compression force, the end plate is expanded in the longitudinal direction.  The vibration energy absorbing baffle plates have a hardness less than that of the tubes.         The heat exchanger of the present invention is particularly useful for severe-duty cycle, vibration-prone vehicular applications.

Abstract: Abstract A novel apparatus and process for producing cement slurry on a batch basis is disclosed.  During the charging of a slurry batcher with water and cement, the cement dust so produced is captured and added back to the slurry being batched in order to minimize health and environmental hazards created by the cement dust.  This is achieved by passing or venting entrapped air and dust in the batcher through air vent and cement dust collection means which in one embodiment comprises a water reservoir through which the air and dust passes.  Dust is captured by the reservoir water and the reservoir water then discharged into the batcher so as to become part of the slurry batch with known and predetermined amounts of water and cement in the slurry.

Abstract: Abstract of the Disclosure Monochromatic infrared radiation of variable wavelengths between 1.0 and 3.5 microns is directed upon a portion of a moving web, and the spectra of infrared radiation reflected from the web portion and of radiation transmitted through the web portion are separately measured by sensors located on both sides of the web.  These spectra are combined to provide an absorption spectrum insensitive to any elastic scattering that is also present.  Measures of the contents of the web constituents are generated by least-square fitting the individual absorption spectra of the constituents to the measured absorption spectrum of the web.  Means for calibrating the reflectance and transmittance measurements and for keeping the sensor viewing windows free of dirt and dust are also disclosed.
