Abstract: ABSTRACT OF THE DISCLOSURE           In a coking process, coal to be coked is preheated in a cascaded whirling bed drier into which the coal is charged from above and exposed to an indirect heat transfer while whirling in a coal-steam mixture.  Hot gas applied to the heating pipes in respective cascades of the drier is branched off from the total amount of hot gases discharged from a dry cooler in which hot coke from the coke oven is cooled by recirculating cooler gas constituted by a partial gas stream discharged from the cascades of the drier and reunited with the other partial stream subject to a heat exchange for generating steam.  Steam from the whirling beds is discharged from the cascaded drier, separated from the entrained dust particles, and then the excessive steam is drained in a branch conduit and the remaining steam is compressed and reintroduced into the lowermost whirling bed in the drier.

Abstract: SPECIFICATION     Title of the Invention Process for Producing Crosslinked Urea-Formaldehyde Polymer Particles Abstract Disclosed is a process for producing fine particles of crosslinked urea-formaldehyde polymer which comprises the steps of synthesizing a precondensate of urea and formaldehyde, allowing the precondensate to react by the addition of an aqueous solution of an acid catalyst, and then neutralizing the reaction mixture, characterized in that the filtrate obtained in the filtration step for separating the polymer particles is recycled to the reaction system at the step of synthesizing a precondensate of urea and formaldehyde and/or the step of allowing the precondensate to react by the addition of an aqueous solution of an acid catalyst and in that the precondensate is obtained by reacting 1 mole of urea with 1.4 to 1.9 moles of formaldehyde at a pH of 6 to 10 and a temperature of 10 to 95°C.           While such fine particles of crosslinked urea-formaldehyde polymer are useful as a filler for improving certain properties (such as opacity and the like) of paper, disposal of the filtrate resulting from the filtration step for separating the polymer particles has been a serious problem.  The disclosed process is carried out in a closed system by recycling of the filtrate and, moreover, the resulting polymer is in the form of fine particles having a diameter of 0.1 to 1.0 µ and hence meets the requirements for a filler of paper (i.e., the capability of improving the opacity and other properties of paper).

Abstract: FABRIC SOFTENING DETERGENT     ABSTRACT OF THE DISCLOSURE:           A particulate synthetic organic fabric softening deter-gent composition product of improved appearance and/or flowabili-ty is made by mixing together 10 to 60% of detergent composition particles having finely divided bentonite powder adhered to external surfaces thereof and 90 to 40% of similar such detergent composition particles devoid of such bentonite powder on the surfaces thereof.  When the detergent composi-tion particles, preferably spray dried, are white and the bentonite is off-color the described product appears whiter than does a "control" wherein the same total proportion of bentonite is agglomerated onto the surfaces of all the detergent particles.  Also, when the bentonite-surfaced particles are higher in content of tacky detergent than the non-bentonite-surfaced particles, which increased detergent content may be obtained by spraying aqueous detergent solu-tion onto the particles before agglomeration with bentonite powder, the flow properties of the product are improved, compared to a product containing the same total proportion of the detergent evenly distributed throughout all the particles.  The bentonite particles are adhered to the detergent composition particles with the aid of an aqueous spray, prefer-ably of a dilute sodium silicate solution, and the agglomerate resulting may be used directly as a detergent composition or may be blended with detergent composition particles not having bentonite on the surfaces thereof.

Abstract: TITLE OF THE INVENTION                       REACTION DRIVE SPRINKLER                      ABSTRACT OF THE DISCLOSURE        A reaction drive sprinkler,  particularly of the large gun type, is provided with an improved drive assembly adapted for full- or part-circle rotation of the sprinkler in steps about the axis of a water supply standpipe.   The sprinkler includes a relatively large and outwardly in-clined range tube (16) from which a relatively high energy water stream (18)  is projected a substantial distance for irrigation purposes.  The drive assembly comprises a drive nozzle (32) mounted on the range tube (16) for bleed passage of a relatively low energy portion (30) of the irrigation water supplied to the range tube and for directing this low energy stream into engagement with one of a pair of oppos-itely angled deflection spoons (26, 28) at the end of a counterbalanced  and pivotally mounted reaction drive arm (24).  The drive nozzle is movable with respect to the range tube and is mechanically shifted by a reversing mechanism (34)  for aligning the low energy stream first for cyclic interruption by one of the deflector spoons to rotate the sprinkler stepwise in one direction through a preselected arcuate path and then for cyclic interruption by the other deflector spoon to rotate the sprinkler stepwise in an opposite rotational direction back through the preselected path.   In one preferred form, the range tube is supported for rotation by a bearing assembly (12) which includes a force-biased seal member (59) responsive to increasing water pressure for increasing frictional resistance to rotation whereby the stepwise movement of the sprinkler is maintained substantially uniform throughout a range of water pressures. Moreover, the range tube is advantageously provided with a discharge nozzle assembly which is adjustable to select the angle of inclination of the projected high energy water stream.

Abstract: Abstract A preconverged color display station 13 is disclosed which is compatible with a computer controlled control unit 11 that provides electrical convergence control signals.  Compatibility is obtained by causing the control unit 11 to transmit the electrical convergence signals to the screen storage memory RAM (random access memory) 24, 25, 26 which normally stores information defining the character and character attributes to be visually provided by the display station CRT screen.  The stored convergence signals are read back to the control unit 11 from the screen RAM.  After all of the convergence signals have been received by the display station and prior to the transmission of character and character attribute information signals to the screen RAM, the contents of the screen RAM is erased. Subsequently, the contents of the screen RAM, which now contains character display information signals, is read out and utilized to define a visual display on a CRT 14. During the time that the screen RAM contains electrical convergence signals, the video of the CRT is blanked. Selection of any of at least three basic colors is provided by the color display station whether or not electrical convergence control signals are provided thereto and whether or not a monochrome or multicolor control unit is coupled thereto.
