Abstract: FUEL ATOMIZING UNIT           Inventor:  Arthur Hayward a citizen of the United States and resident of the Bronx, New York.     ABSTRACT OF THE DISCLOSURE          A fuel atomizing unit interposable in a conduit feeding to a combustion chamber a relatively cold mixture of fuel droplets dispersed in air.  The unit is constituted by an electrical heating element placed between a pair of spaced mesh screens to define a permeable assembly having a pocket therein.  The assembly functions as a restriction in the con-duit whose impedance to flow is in the order of about 15 to 20%, whereby the screen intercepts the droplets to create a suspension in air of minute fuel particles to produce a downstream mist which is forced by the restriction to assume a vertex-like flow pattern.  The heat supplied to the pocket by the heater is sufficient to raise the temperature of the mist to a level conducive to complete combustion in the chamber, whereby no fuel is wasted and the exhaust of the chamber is substantially free of pollutants.

Abstract: ABSTRACT             A saturated reactor adapted for direct connection to an EHV line and thus constituting a combined reactor and transformer.  A problem arises in that earthing of the primary winding star point would normally short circuit the 3rd harmonic.  The invention overcomes this by series connection of primary coils coupled to three limbs whose fluxed are spaced at 40°.  3rd harmonic voltages therefore cancel in the series primary windings.  The series primary windings may be obtained as separate coils on individual limbs or as one coil (per phase) embracing three limbs.  Elimination of the 3rd harmonic enables the ninth harmonic to be short circuited in a mesh winding.

The elastically yieldable fastener comprises an elastically yieldable strip bent onto itself and forming two superimposed branches.  A clamping device extends through apertures in the two branches for clamping the strip to the support of the rail.  The upper branch has a boss disposed between the aperture of the upper branch and the free end of the latter and between lateral portions of the upper branch which are adapted to bear against the lower branch when the fastener is clamped by the clamping device.  The clamping device defines a lower surface for contacting the upper surface of the boss and the two surfaces have the same shape so that, in the normally clamped position of the fastener, the  portion of the branch carrying the surface contacting the clamping device is raised with respect to the lateral portions.

The adjusting rotor member has an outer end engaging the other of the lens support and the temple.  The sleeve has a length less than the depth of the associated socket, and is formed with a flange on its outer end limiting forcing of the sleeve into the socket, under pressure, to a depth in which the flange is flush with the surface of the lens support or temple in which the bore or socket is formed.  The adjusting member has a stop at its inner end preventing displacement from the sleeve, and is formed with a notched or knurled operating head particularly configured for operative association with tools for assembling the rotor in the sleeve and inserting the adjust-ing assembly in the socket.  In a modification, the rotor member is threaded-ly engaged in an internally threaded aperture in a plate portion of a half hinge, the internally threaded aperture being axially aligned with a socket.
