Abstract: ABSTRACT OF THE INVENTION    Hollow plastic microspheres made from thermo-plastic or thermosetting plastic compositions are described.      The hollow plastic microspheres are made by forming a liquid film of thermoplastic or thermo-setting plastic composition across a coaxial blowing nozzle, applying a blowing gas at a posi-tive pressure to the inner surface of the plastic film to blow the film and form an elongated cylinder shaped liquid film of plastic.  A trans-verse jet is used to direct an entraining fluid over and around the blowing nozzle at an angle to the axis of the blowing nozzle.  The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.  The continued movement of the entraining fluid over the elongated cylinder produces asymmetric fluid drag forces on the cylinder and closes and detaches the elongated cylinder from the coaxial blowing nozzle and the detached cylinder by the action of surface tension forms into a spherical shape.      Quench nozzles where the plastic is thermo-plastic and heating nozzles where the plastic is thermosetting are disposed below and on either side of the blowing nozzle and direct cooling fluid or heating fluid at and into contact with the plastic microspheres to rapidly cool or heat and cure, solidify and harden the plastic to form hard, smooth hollow plastic microspheres.

Abstract: 16                   48,166 ABSTRACT OF THE DISCLOSURE       The static VAR generator of the fixed capacitor switch-controlled inductor type is taught.  The inductive element has a break point in its inductive characteristic. That is, below a certain predetermined current, the induc-tance is one value and above the latter current the induc-tance is another value.  This has the effect of providing a reduced value of inductive reactance above a certain inductive current level thus making it possible to sig-nificantly increase the inductive current above its normal range with a small increase of the switch conduction inter-val.  In one case a saturable iron core reactor is utilized to achieve the break point and in another ease two induc-tive elements are provided -- one of which is controlled by a switch which places the latter inductor into circuit arrangement with the first at the time that the current ex-ceed the predetermined value.
