  • Patent number: 10817666
    Abstract: The present invention is a method and apparatus for narrative content generation using narrative frameworks by receiving a first phrase variation and a second phrase variation and displaying an error indication when the first phrase variation fails to satisfy a criterion relative to the second phrase variation. If there is an error indication, alternate phrase variations are received and compared against the first phrase variation until an alternate phrase variation is selected that has no error indication. Additionally, multiple sets of operators for updating one or more narrative phrases selected for inclusion in the narrative content framework may be utilized to update selected phrases after inclusion in the narrative framework but prior to finalizing the narrative content to be output.

  • Publication number: 20200263688
    Abstract: Disclosed is a plunger for use in a sucker-rod pumping system. The plunger reciprocates within a barrel. The plunger comprises first, second, and third sections, in which the first and third sections are sealed against the barrel and in which a second section is between the first and third sections and in some embodiments may be a pull tube. A through passage for production fluid is provided, along with a pressure balancing chamber that is connected to the through passage via a sand snare, where the pressure balancing chamber is operable to equalize pressure on longitudinal sides of the seals, whereas the sand snare operates to restrain solids from reaching the pressure balancing chamber from the through passage (which is carrying the production fluid) and thereby create a slippage flow in the pressure balancing chamber, which equalizes pressure between the balancing chamber and the plunger's through passage.
