  • Patent number: 8187470
    Abstract: Some mineral processing plants encounter difficulties in dewatering pulps using clarifier/thickener (C/T) equipment due to a layer of fine particles, air bubbles and chemicals formed at the top of the liquid in the thickener. Such layers are very stable and form a cap on the C/T. The dewatering performance of the C/T then deteriorates under these conditions, and a high percentage of solids is contained in the thickener overflow. A process for removing water from rock slurry containing a wide range of particle sizes in mineral processing operations has been developed. The process includes: (a) classifying the feed slurry into two size fractions, namely a coarse fraction and a fine fraction, (b) treating the fine fraction (and the coarse fraction if required) with a selected flocculant, and (3) thickening the flocculated slurry in sedimentation equipment to separate liquid from solids.

  • Patent number: 8182698
    Abstract: A chemical process to improve the filtration performance for the removal of gypsum from phosphoric acid/gypsum slurry using a filtration aid that is selected from a class of polymers, lower molecular weight anionic polyelectrolytes, which previously have not been used for this application. The polymer is CMC or Carboxymethyl Cellulose, which is a polymerized cellulose ether. CMC is found to be extremely effective for phosphoric acid/gypsum slurry that was produced from igneous phosphate rock. CMC is also available in food grade, which is novel for filtration aids for the production of phosphoric acid which may be used for human or animal feed.

  • Patent number: 8069595
    Abstract: The invention is a product that allows one to determine precisely how many times a particular garment has been worn. By removing the guesswork from the “wash-or-wear equation,” the consumer knows the garment is sufficiently clean, and will generally be able to extend the wearing of the garment between cleanings. Use of the invention will result in the conservation of resources in terms of reduced consumption of water, energy, detergent/softeners, and dry cleaning services; it will also increase the life span of garments as well as cleaning/drying appliances.

  • Patent number: 7932690
    Abstract: A system and associated method for preventing damage to an adjacent wall surface of an electrically operated bed that utilizes a normally closed/momentarily open switch assembly attached to the bed frame at a location such that when the bed fame is maneuvered toward an adjacent wall surface, a head of the switch contacts the wall surface before any other part of the bed frame or a proximity sensor switch is activated when the switch head is in the prescribed range from the wall surface. The push button switch is in electrical communication with the bed frame operational circuitry. When the switch activated from its depression from thw all surface contact or its proximity to the wall surface, the electrical circuitry in the system circuitry is interrupted thereby stopping the operation of the bed frame from being maneuvered and preventing damage to the wall surface.
