  • Patent number: 5725793
    Abstract: The present invention proposes adding an alkaline solution or a mixture of two or more alkaline solutions to the agent system of absorption machines operating with ammonia or methylamine as the agent and water as the solvent. This addition of an alkaline solution or an alkaline solution mixture has a number of advantageous effects. These are, i.a.1. The dissolving respectively expelling heat of the agent is reduced, raising the output figure.2. The agent vapor generated is very pure. A dephlegmator is obviated.3. The alkaline solution makes steel surfaces inert when sealed from air and in a high vaccum, thereby obviating corrosion inhibitors.4. The viscosity of the solvent is reduced, decreasing pump operation.

  • Patent number: 5723434
    Abstract: Isotropic liquid detergent composition comprises specific soil antiredeposition polymers containing a hydrophilic backbone and monomer with hydrophobic side chains. When the molar ratio of the number hydrophilic groups to number of hydrophobic groups on said polymers is below certain critical levels, it has been unexpectedly found that the stability (i.e., clarity) of the composition remarkably increases. The solubility of the polymer is further dependent on the type and amount (minimum required) of hydrotrope; surfactant type and levels; and minimum electrolyte levels.

  • Patent number: 5723433
    Abstract: A method of removing solvents from a paste includes introducing a heated paste into a channel of a dryer under pressure selected so as to avoid flashing of any of the components of the paste. At the inlet of the channel, the pressure is dropped, resulting in the flashing of selected components of the paste. As the paste advances through the channel heat is applied to the paste. Vapor liberated during the flashing acts as a motive force to convey the paste along the channel. The resulting concentrate is collected at an outlet of the channel.
