Abstract: METHOD OF POLYMERIZING POLYDIORGANOSILOXANE  FLUID-FILLER MIXTURE USING SULFURIC          OR SULFONIC ACIDS           Abstract A method of polymerizing an oligomer comprising a polydiorganosiloxane, polydiorganocyclosiloxane, or mixture thereof in the presence of reinforcing filler using a catalytic amount of sulfuric or sulfonic acid is described. The sulfonic acid is of the formula XSO3H wherein X is selected from the group consisting of halogen, alkyl, aryl, alkoxy, and alkaryl radicals.  The dispersion of reinforcing filler in polydiorganosiloxane is produced using less energy, with fewer manufacturing steps than current commercial processes.  The silicone polymer-filler mixture produced by this method is useful as electrical insulation compounds, in greases, and in producing curable compositions useful as sealants, caulking compounds, and heat curable silicone elastomeric compositions.

Title: Nebulizer particularly adapted for analytical  purposes
Inventor: KARNICKY JOSEPH F
IPC: G01N1/28
Filed: 1985-09-11
Granted: 1990-04-24
Abstract: Abstract Nebulizer Particularly Adapted For Analytical Purposes A nebulizer for analytical purposes includes a needle through which flows a liquid to be nebulized. The liquid flows from the needle onto a diaphragm planar surface that is vibrated in successive pulses. A continuous bridge of the liquid subsists between the liquid and the planar surface when the diaphragm is in the non-vibrating state.  The liquid is nebulized to an aerosol when the diaphragm is pulsed. The needle and diaphragm are always spaced from each other.  A wick on the planar surface in contact with the film removes excess amounts of the liquid not involved in forming the aerosol.  The diaphragm vibration is pulsed by a piezoelectric crystal that responds to an FM wave whose frequency is swept over a band spanning the resonant frequency of the crystal. The crystal is configured as a spherical segment to direct a focused pressure wave on the diaphragm via a liquid medium.  The diaphragm has a thickness that is about one-half wave length of the pressure wave supplied to the liquid medium by the crystal, to provide destructive interference of waves reflected from opposite faces of the diaphragm.  A carrier gas for the nebulized aerosol is supplied to the diaphragm planar face to form a curtain about the liquid flowing from the needle to the diaphragm.  The liquid circu-lates between the diaphragm and crystal to cool them and enable gases in the liquid to be removed.

Abstract: Abstract:     For determining the charging of a charcoal filter with gases and vapors the acoustical and the electrical impedance of the charcoal layer are measured. The more the filter is charged the greater will be the density of the charcoal layer and therewith its acoustical conductivity. The charging of a charcoal layer with water vapor results in an increase of the acoustical as well as of the electrical conductivity. A charging with other gases or vapors however has no influence on the electrical conductivity. By comparing the acoustical impedance and the electrical impedance respectively of a partially charged charcoal layer with the impedance of a non-charged charcoal layer and by subsequent comparison of the impedance changes caused by such charging the influence of water vapor can be eliminated.          A signal is generated corresponding to the charging of the charcoal filter with other vapors and gases which signal may be used for indicating the condition of the filter and for generating an alarm if the filter becomes exhausted.
