Abstract: ABSTRACT OF THE DISCLOSURE           A decoder is provided for four channel FM stereophonic composite signals including a first pilot signal, a main channel signal, a first sub-channel signal suppressed carrier amplitude modulated on a first subcarrier having a frequency twice that of the first pilot signal, a second sub-channel signal suppressed carrier amplitude modulated on a second subcarrier having the same frequency as the first subcarrier and having 90° phase difference with respect to the first subcarrier, a third sub-channel signal suppressed carrier amplitude modulated on a third subcarrier having a frequency twice that of the first subcarrier, and a second pilot signal indicative of the four channel stereo-phonic signal broadcasting mode and with a frequency interposed between the frequency bands of the first and third subcarriers; which decoder comprises a control signal generator controlled by the first pilot signal and producing first and second control signals in predetermined phase relation to the first pilot signal and with frequencies that are respectively equal to, and twice the frequency of the first pilot signal, a signal combining circuit supplied with the first and second control signals for producing a switching signal, and a switching circuit controlled by the switching signal for detecting the second pilot signal in the four channel FM stereophonic composite signals.  When the second pilot signal is thus detected, signals from the control signal generator are employed for demodulating the four channel FM stereophonic composite signals into the corresponding four discrete audio signals; whereas, when the second pilot signal is not detected, for example, in the case of the reception of two channel stereophonic broadcast transmission, the aforesaid second control signal is employed for demodulating the two channel FM stereophonic composite signals into the two corresponding discrete audio signals.

Abstract: Abstract A coating medium for application to a substrate to form a coating which is curable to a highly cross-linked polymeric state.  A coating medium is prepared by reacting, in a suitable solvent for at least one reactant, an aromatic diamine and an aromatic dianhydride, with the reactants in the molar ratio of two-to-one respectively.  The diamine is dissolved in a solvent, and the dianhydride is slowly added to the solution to form a diamide-diacid-diamine monomer. The reaction is carried out at a temperature below that at which imidization occurs.  The reaction product may be made water soluble by the addition of a volatile base.  A coating of the medium is applied to a substrate as a thin film and the film coating is cured at a temperature sufficient to form a highly cross-linked polymeric coating on the substrate.  Suitable aromatic dianydride reactants include 3,3',4,4'-benzophenonetetracarboxylic dianhydride and 4,4'-(2-acetoxy-1,3-glyceryl)bis-anhydro trimellitate, and suitable aromatic diamine reactants include 4,4'-diaminodiphenyl methane, 4,4'-diaminodiphenyl ether, and 1,3-diamino benzene.  Upon application of a coating of the monomer solution to a substrate and upon cure of the coating to drive off the solvent and effect polymerization, inter-molecular amidization and imidization reactions occur resulting in what are believed to be highly cross-linked ladder-type polymeric coatings.

Granted: 1980-04-01
Abstract: ABSTRACT OF THE DISCLOSURE     A method facilitating the rapid and objective classification and/or identification of an unknown biolog-ical specimen is disclosed.  A physical sample of the specimen is controllably heated in accordance with a pre-determined nonisothermal time dependent function causing the sample to undergo controlled thermal degradation and give off a characteristic time dependent sequence or evolution pattern of gaseous degradation components (molecular fragments).  This sequence of gaseous degrada-tion components is then directly passed into an ionization source and ionized to provide a respectively corresponding time dependent sequence of characteristic ions.  These ions are then analyzed in a mass spectrometer and measured data is recorded representing the respective quantities of ions having particular masses being produced as a function of time or temperature.  This recorded data for  an unknown biological specimen is then correlated with analogous time or temperature dependent data earlier recorded for known biological specimen thereby facilitating the classification and/or identification of the unknown biological specimen.          The method may be used to facilitate the classification and identification of many different types of biological speci-men such as, for example, biological organisms (e.g., bacteria, yeast, molds, fungi, viruses and unicellular animals) and/or biological tissues (e.g., lymphocytes, leukocytes, phagocytes, erythrocytes and platelets).
