A powder suspension device is provided having a hollow container adapted to contain a quantity of powder therein and a means for introducing air under pressure adjacent the bottom of the container to place the powder in suspension in the container. A blower is also provided having an inlet and a tangential outlet from which a stream of air emerges. A powder return housing is located beneath the blower and above the powder suspension device and in communication with both of these devices. A pair of tangential inlet pipes arranged approximately 180° apart on the return housing are adapted to return excess powder from the powder dispensing devices. A pair of Venturis having their suction inlets connected to the side of the powder suspension device are connected to streams of air for withdrawing quantities of powder suspension from the container and for introducing the powder suspension into the tangential outlet from the blower. A pair of pipes or hoses connect from the tangential outlet of the blower with the inner housings of the two powder dispensers for supplying a stream of air-powder suspension to the powder dispensing devices, and a second pair of hoses or pipes connect from the spaces between the inner and outer housings of the two dispensers with the two tangential inlet pipes on the return housing. The Venturis are connected so thattheir outlets go into the two pipes or hoses leading from the tangential outlet from the blower to the two inner housings on the powder dispensers.

Abstract: ABSTRACT: 24.11.1980 Electrically variable impedance circuit with feedback compensation.      A variable impedance circuit in which nonlinearities caused by the application of a signal are substantially reduced by the use of a feedback circuit for cancelling out the added input current due to the application of the input signal. By using a feedback circuit to obtain the desired improvement in linearity, the gain of the feedback loop can be tailored to obtain the necessary impedance range and output swing in a ciruit capable of operating at relatively low power supply voltages.

Abstract: ABSTRACT OF THE DISCLOSURE    A process is disclosed for the preparation of liquid, storage-stable, polyisocyanate compositions containing a release agent formed in situ which compositions are useful, for example,  as binder resins in the formation of particle boards which latter, because of the presence of the release agent, show no tendency to adhere to the face of metal platens used in their formation.  The process comprises heating an organic polyisocyanate (polymethylene polyphenyl polyisocyanate preferred) with an acid phosphate (e.g. a mixture of mono- and di-alkyl acid phosphates) under conditions controlled as to time and temperature so as to yield a product which is storage stable and shows no tendency to deposit solid or to separate into two liquid phases.                            -i-

Abstract: ABSTRACT OF THE DISCLOSURE    A process for the fractionation of a porous or fluid-perme-able hydrocarbonaceous solid, such as coal, containing an admix-ture of mineral matter and hydrocarbonaceous matter, into a sepa-rate mineral enriched fraction and a separate hydrocarbonaceous enriched fraction is disclosed.  In this process, the hydrocarbon aceous  solid  is  comminuted  to  convert  the  hydrocarbonaceous matter in the coal into discrete particles having a mean volu-metric  diameter  of  less  than  about  5  microns  without substantially altering the size of the mineral matter originally present in the coal.  As a result of this comminution, the hydro-carbonaceous particles can be fractionated from the mineral part-icles to provide a hydrocarbon fraction having a lesser concentra tion of minerals than in the original uncomminuted material and a mineral fraction having a higher concentration of minerals than in the original uncomminuted material.    A preferred method for comminuting the porous or fluid-perm-eable hydrocarbonaceous solid, i.e.   coal, is to first form a slurry of coal and a fluid such as water or methanol.  This slurry is then heated and pressurized to temperatures and pressures in excess of the critical temperature and pressure of the fluid.    The resultant supercritically heated and pressurized slurry is  then passed  to an  expansion  zone maintained  at  a  lower pressure, preferably about ambient pressure, to effect comminu-tion or shattering of the solid by the rapid expansion or explo-sion of the fluid forced into the coal during the heating and pressurization of the slurry.    The supercritical conditions employed produce a shattered product comprising a mixture of discrete comminuted hydrocarbon-aceous particles having a volumetric mean particle size equiva-lent to less than about 5 microns in diameter and discrete in-organic and mineral particles having a mean particle size sub-stantially unchanged from  that  in  the original solid.   This mineral fraction, in turn, is then fractionated from the hydro-carbonaceous fraction.   The product hydrocarbonaceous fraction has a lower density, greater solvent solubility and different re-activity to oxygen than does the feed solid.  This hydrocarbon-aceous fraction also includes a subfraction of particles having a mean particle size, by volume distribution, equivalent to less than about 2 microns in diameter which contain substantially no sulfur compounds.

Abstract: ABSTRACT OF THE DISCLOSURE     ULTRASENSITIVE APPARATUS AND METHOD FOR DETECTING CHANGE IN FLUID FLOW CONDITIONS, PARTICULARLY IN RELIEF FLOWLINES ASSOCIATED WITH A CHEMICAL OR REFINERY COMPLEX     Transient change in heat flux due to ultrasmall variation in flow conditions (say from no flow-to-flow), particu-larly within a series of relief flowlines forming a component part of a flaring system associated with a chemical or refinery complex, is surprisingly useful in pinpointing a source of plant upset.  Result:  corrective action can be undertaken.  In one aspect, the change in flux is monitored within each major relief flowline using a heat flux transducer-meter in series with signal indicating means, such as a recorder and/or an audio-alarm system. Cascading the signal output, i.e., serially combining the outputs of N thermocouples of the transducer-meter, enhances sensitivity. In a preferred case, N is about 80 but can be as high as 320, if desired.
