A method or system for raising gas and liquid from a well used in in situ heating of a formation. Such heating may be done by radio frequency having an appropriate wave length in the earth e.g. about fifteen meters. The well has a production tube suspended from the well head. And, the method steps include sweeping the annulus with dry gas to drive the products up the production tube, at low flow. Also, another step is that of measuring the pressure differential between the annulus and the outlet of the production tube. And, another step is that of increasing the flow of the dry gas whenever the pressure differential exceeds a predetermined minimum. The increased flow is continued for an interval long enough to clear the liquid product that has risen in the tube and caused the differential pressure increase.

A static-type fluid-mixing method. It deals with mixing different fluids in a stream which are separated longitudinally. A portion of the stream is diverted laterally and the remainder is reversed after continuing in the original direction for a given distance. Both parts are then mixed by joining one another down stream. A static-type mixer. It has a conduit for carrying a stream of fluids separated longitudinally. It includes passages for diverting a portion of the stream laterally, and means for longitudinally reversing the remainder of the stream to rejoin the diverted portion after a given amount of flow of the stream.

Method and apparatus for static type fluid mixing

A pivoted pointer or stylus is mounted for actuation by reciprocatory plunger action. It has a stop associated with the plunger to hold the stylus locked in a neutral position until the plunger is actuated. The stylus has a cam action surface for cooperating with another part of the stop after the stop has moved to release the stylus. The cam action causes pivotal movement of the stylus to indicate an event.
