Abstract: ABSTRACT OF THE DISCLOSURE        The present invention is directed to a process and composition for accelerating the activation of a polymeric surface prior to electroless plating thereof, wherein there is employed a solution comprising a relatively dilute inorganic acid, a metal salt selected from Group VIII B of the Periodic Chart but excluding iron, and a compound capable or ionizing to produce a source of fluoride ions,  By so proceeding, microscopic cavities in the polymeric substrate are thoroughly cleansed of residual tin ions which remain subsequent to rins-ing of the polymeric body following the conventional activation step employing an acidic solution of palladium chloride and stann-ous chloride. The removal of palladium ions, which have a catal-ytic effect in the electroless plating operation, is minimized by the composition and process of this invention, and further, in addition to other advantages, there is achieved relatively low and uniform values of part resistance and contact resistance.

Abstract: ABSTRACT A method is provided for forming a document adapted to have graphical information applied thereto which cannot be detected by the detectors of copy-ing machines having spectral responses in the range of 350 to 600 millimicrons. This information can be detected by human eyes having spectral responses in the range of 425 to 675 millimicrons.  A background is produced on a sheet of material and has a reflectance which is substantially 4% over the wavelength range of 325 to 525 millimicrons and increases to 13% at about 575 millimicrons. Thus insufficient reflected energy is available from the background to be detected by the detectors.  The reflectance of the graphical information is about 5%.  The invention also includes the sheet of material produced by this method.

Abstract: ABSTRACT OF THE DISCLOSURE    This invention describes a furnace system for the reduction of nitrogen oxide containing gases which utilizes a two-chambered refractory lined furnace.  Fuel gas and stoichiometric air is introduced into the first chamber to provide an ambient temperature sufficient for the reaction or steam and hydrocarbon gases which are introduced into the first chamber to provide a reducing atmosphere.  The nitrogen oxide (NOx) containing gases are also introduced into the first chamber where the Nox is reduced.  The gases then pass into the second chamber where they are rapidly cooled to a temperature below that at which there is thermo-regeneration of nitrogen oxides.  Additional air is supplied to the second chamber for the combustion of combustible gases remaining therein after reduction, care being taken that the temperature never rises above the temperature at which there is substantial regeneration of nitrogen oxides.

Abstract: ABSTRACT OF THE DISCLOSURE           An electronic remote control transmitter employs a two transistor cascade oscillator having positive and negative feedback loops.  The oscillator voltage is supplied through a switch assembly containing a plurality of momentary contact switches to a pair of voltage dividers supplying signal voltages in predetermined ratios to a two branch circuit in the negative feedback loop.  One branch contains an inductor and the second branch a capacitor.  Closure of any switch completes the DC circuits for the transistors.  Signal voltage is supplied to the branches to produce a minimum amplitude, zero phase shift condition which establishes oscillation at that predetermined frequency.  The output of the oscillator is amplified by a third transistor and supplied to an ultrasonic transducer for generating acoustical control signals.
