| 20110200860 | BATTERY COOLING WITH MIST EVAPORATION AND CONDENSATION - A battery pack cooling system may utilize a shroud defining a throat and a body, which may contain a battery pack. An evaporator may be arranged against the battery pack. A liquid coolant delivery pipe may deliver liquid coolant from a reservoir to the throat section with the aid of gravity, a pump, or an ultrasonic misting device. A spray nozzle may also deliver liquid coolant into the throat. When in the throat, liquid coolant mixes with air blown by a fan. Gaps in the battery pack may align with gaps of the evaporator to permit liquid and air to be blown completely through the battery pack and through the evaporator. A refrigeration system including a refrigerant compressor, a condenser and an expansion device work to cool the evaporator to condense, cool and remove liquid coolant from the liquid and air mixture, and deposit it in the reservoir. | 08-18-2011 |
| 20110239697 | EVAPORATOR UNIT - An evaporator unit comprising an evaporator, an internal heat exchanger defining a high pressure flow passage and a low pressure flow passage, an expansion device connected downstream of the high pressure flow passage of the internal heat exchanger and upstream of the evaporator. The internal heat exchanger is attached to the evaporator. With the above structure, the internal heat exchanger can utilize the remaining cooling capability of the refrigerant exiting from the evaporator for its greatest benefit. | 10-06-2011 |

| 20110160347 | STABILIZED REDISPERSIBLE POLYMER POWDER COMPOSITIONS - A water redispersible polymer powder may be produced by drying an aqueous mixture of a water insoluble film-forming polymer and a colloidal stabilizer comprising a chelating agent to obtain a water redispersible polymer powder, where the amount of chelating agent is at least 0.1% by weight, preferably at least 1% by weight, most preferably at least 3% by weight, based upon the weight of the water insoluble film-forming polymer. Dispersions or polymer compositions containing a chelating agent as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. The chelating agents are stable at high pH and so high pH spray dryable compositions containing them as a colloidal stabilizer may sit or be stored for prolonged periods of time prior to spray drying without loss of effectiveness of the colloidal stabilizer. | 06-30-2011 |

Dispersions or polymer compositions containing a chelating agent and water soluble polymer as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. The colloidal stabilizer composition provides unexpectedly superior redispersibility for water insoluble film-forming polymers having very low carboxylation levels. | 06-30-2011 |
| 20110257305 | REDISPERSIBLE POLYMER POWDERS PREPARED FROM LOW CARBOXYLATION STYRENE BUTADIENE-BASED LATEX - A water redispersible polymer powder is produced by drying an aqueous mixture of a low carboxylation, low Tg, large average particle size water insoluble film-forming polymer latex or emulsion and a colloidal stabilizer.

Dispersions containing the polymer and a polyvinyl alcohol as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. Cement compositions such as mortars, which contain the redispersible polymer powder exhibit unexpectedly lower rates of viscosity buildup for better workability or troweling, faster set time, and superior heat flow characteristics. | 10-20-2011 |
