  • Patent number: 4666738
    Abstract: A free flowing particulate heavy duty laundry detergent containing no more 8.7% of phosphorus (from phosphate) is comprised of sodium tripolyphosphate particles having nonionic detergent in the interior and on the surface thereof, which adheres a coating of smaller particles of ion-exchanging zeolite to the phosphate. Also within the invention is a method of making such a product by pre-mixing spray dried sodium tripolyphosphate particles and smaller zeolite particles and admixing with them, as by spraying, in liquid form, onto moving particles, a normally liquid or pasty nonionic detergent, such as a higher fatty alcohol polyethylene oxide condensation product, which penetrates the sodium tripolyphosphate particles and adheres zeolite particles to the surfaces thereof.

  • Patent number: 4666740
    Abstract: A free flowing phosphate-free particulate heavy duty laundry detergent is comprised of particles of a mixture of sodium carbonate and sodium bicarbonate having nonionic detergent in the interior and on the surface thereof, to which is adhered a coating of smaller particles of ion exchanging zeolite. The product made is exceptionally free flowing and, although the particles are relatively large, is also of high bulk density (over 0.6 g./cc.). Also within the invention is a method of making such products by contacting the particles of mixed sodium carbonate and sodium bicarbonate with a normally liquid or pasty nonionic detergent in the liquid state so that the detergent is largely absorbed by the particles and coats the surfaces thereof, which are then coated with powdered zeolite which adheres to the surface nonionic of the particles and makes them free flowing.

    Abstract: A single particle penetration phosphor employs La.sub.2 O.sub.2 S:Tb particles as a core particle having a thin layer of La.sub.2 O.sub.2 SO.sub.4 :Tb formed thereon by oxidation to provide a barrier which must be penetrated by excitation electrons to produce narrow bandwidth green spectral emission from the particle. The thin barrier is in turn coated by a layer of YVO.sub.4 :Eu particles which produce narrow bandwidth red spectral emission upon electron excitation. The barrier layer increases the voltage turn on characteristic of the green carrier host thereby causing the electron irradiated phosphor to radiate in the red spectrum for low voltages and in the green spectrum for higher voltages. Additionally, methods are disclosed for synthesizing the above single particle penetration phosphor.

  • Patent number: 4440800
    Abstract: A liquid or powder material can be dispersed by the application of electrostatic fields. The phenomena, referred to as "electrodispersion" is the dispersion by an intense electric field of part of a static bed of liquid or powder into a stable cloud of rapidly moving particles, and the maintenance of a dynamic equilibrium between the static and dispersed phases. The density of the dispersed cloud of particles varies with a number of factors, including the field strength and the nature of the powder. The electrodeposition effect is employed to produce a uniform and durable coating of controlled thickness on the individual particles, by the generation of a vapor of the desired coating--typically a metal or semiconductor material--and allowing the vapor to permeate the dispersed particles. The electric field ensures that only the particles are coated, and the dispersed particles, having the same charge, repel each other, avoiding agglomeration.

  • Patent number: 4406808
    Abstract: A free flowing, phosphate free high bulk density particulate heavy duty laundry detergent is prepared by spray-drying an aqueous slurry of ion-exchanging detergent building zeolite particles, sodium carbonate and sodium silicate which has been sheared to reduce the viscosity thereof, followed by mixing nonionic detergent in liquid form with the spray-dried base beads to absorb the detergent into the beads.

  • Patent number: 4387195
    Abstract: Disclosed herein are fired ceramic wares possessing hydrophobic properties throughout the bodies thereof. The ware is prepared utilizing a water-reduced ceramic body composition containing a quantity of a finely-divided sub-micron amorphous silica or alumina. This ceramic body composition is formed into a green ware, the ware dried and fired at relatively low temperature and the fired ware treated with one or more reactive organosilicon compounds whereby organosilicon groups are caused to chemisorb onto the surface of the finely-divided amorphous oxide component.

  • Patent number: 4383852
    Abstract: In a generally elongated reaction tube at an elevated temperature, a reducing gas stream is caused to flow along the axis of the reaction tube and a metal-halide gas stream diluted with an inert carrier gas is caused to flow in the same direction as but at a different velocity relative to the reducing gas stream. The two gas streams contact each other in a laminar manner and form an unstable interface region therebetween wherein the metal halide gas is reduced to form fine metal particles with uniform particle size.

  • Patent number: 4372882
    Abstract: Detergent compositions containing low levels of substituted polyamines are disclosed. The polyamines are substituted by one long chain alkyl or alkenyl group and by at least two alkylene oxide radicals attached to different nitrogens. Preferred compositions produce a laundry liquor pH in the range from 8.5-12.0; and frequently contain water-soluble or water-insoluble detergent builders.These compositions exhibit a broad range of textile treatment benefits particularly enhanced soil release and cleaning properties.

  • Patent number: 4356020
    Abstract: This invention relates to fertilizer compositions containing alkylene oxide anticaking agents. More particularly, this invention relates to a method of decreasing the caking during storage in a hygroscopic salt or fertilizer which normally cakes on storage, which comprises uniformly admixing with said hygroscopic salt or fertilizer an effective amount of an anticaking agent consisting of one or more compounds selected from the group consisting of adducts of from 6 to 15 mols of ethylene oxide and/or propylene oxide onto 1 mol of a .beta.-hydroxyalkyl-diethanolamine of the formula ##STR1## wherein R.sup.1 is an alkyl of from 1 to 18 carbon atoms and R.sup.2 is hydrogen or alkyl of from 1 to 16 carbon atoms, the sum of the carbon atoms in R.sup.1 and R.sup.2 being from 8 to 18.
