Abstract: WEEDER FOR INLAND WATERWAYS                    ABSTRACT OF THE DISCLOSURE     A weeder capable of removing large and small sized weeds from inland waterways is arranged for towing off the back of a row boat as well as for manul operation.  The weeder is in the form of a rectangular expanded metal section pivotally attached to towing ropes at opposite ends.  The sides of the expanded metal section are sheared to form a V-groove or slot configuration for trapping the weeds along the bed of the waterway where the roots meet the weed stalk.  The expanded metal perforations allow the weeds to be carried to the surface of the water while allowing the water to escape between the perforations.  One side of the expanded metal section is provided with an additional expanded metal section to form V-grooves of smaller width to remove the smaller weeds.

Abstract: A method is provided for recovering particulate crystalline poly(arylene sulfide) from a polymerization reaction resulting in a liquid reaction mixture, comprising a liquid-phase poly(arylene sulfide), a polar organic solvent, and water.  The liquid reaction mixture is contacted by an amount of a vaporized phase separation agent at least sufficient to effect a phase separation of the liquid-phase poly(arylene sulfide)  component from the polar organic solvent component.   The vaporized separation agent comprises a vaporized liquid which, when in its liquid-phase, is characterized as (1) soluble in said polar organic solvent,  (2) a nonsolvent for poly(arylene sulfide), and (3) able to effect a phase separation of the liquid-phase polymer from the polar organic solvent.  A subsequent reduction in the temperature of the liquid reaction mixture produces a reaction mixture slurry comprising a particulate poly(arylene sulfide).  Also provided is a method for recovering  particulate  crystalline  poly(arylene  sulfide)  from  a polymerization reaction resulting in a reaction mixture slurry comprising a particulate poly(arylene sulfide), a polar organic solvent, and water, wherein the particulate poly(arylene sulfide) is liquified resulting in a liquid reaction mixture.  The liquid reaction mixture is contacted by the vaporized phase separating agent as described above.   A subsequent reduction in temperature of the liquid reaction mixture produces a reaction mixture slurry comprising a particulate poly(arylene sulfide).

Abstract: ABSTRACT OF THE DISCLOSURE       Capacitive sound transducer of a very small construction, in particular a microphone has at least two joint semiconductor chips, which embody a membrane unit and a fixed counter-electrode structure.  The acoustic active portion of the membrane unit(1) with at least one counter-electrode structure(3), which is separated from the membrane unit by means of an air gap, forms a system which is comparable to a field effect transistor.  The membrane unit which is formed of a semiconducting ground material encompasses an acoustically active membrane surface (2), one side (5)of which which confronts the counter-electrode structure is electrically conductive.     The counter-electrode structure(3)has a semiconductive base material out of which there is machined a channel length which has been limited by a source-drain arrangement, the geometric width measurement of which is on the order of magnitude of a tenth of the lateral measurement of the active membrane surface.

The selected module provides a response message to the CPU.  The protocol provides a comprehensive response format which identifies the responding module, type of response, and if in error, who detected the error and type of error detected.
