Title: Baseband speech synthesis
IPC: G10L19/02
Filed: 1972-01-27
Abstract: 1344019 Vocoder excitation generator INTERNATIONAL BUSINESS MACHINES CORP 27 Jan 1972 [25 Feb 1971] 3793/72 Heading H4R  In a speech synthesizer in which a low frequency portion of the speech spectrum is transmitted and distorted to derive an excitation signal for synthesis of a higher frequency portion of the speech spectrum, zero crossings of the waveform in a particular direction are detected and pulses generated, each of which represents by its amplitude or duration the time interval between a pair of successive zero crossings. In an analogue embodiment positive going zero crossings of the low frequency portion of the speech cause triggering of a sawtooth generator tile output from which is differentiated to provide pulses, generated during the flyback period, of constant amplitude whose width is dependent on the excitation frequency. In an alternative embodiment, Fig. 4(a), operating digitally, the sign of the low frequency band of the speech signal is fed to an exclusive or gate XOR both direct and via a one clock pulse delay T1 to derive pulses on each of the zero crossings. Combination with the original signal, SIGN, in AND1 provides pulses only on positive going zero crossings which are used after a delay T2 to reset a counter CO, which provides a staircase signal on its output. The undelayed pulse is used to sample the staircase just before resetting so that the output S is a pulse whose amplitude is dependent on the time elapsed since the previous resetting, and hence the excitation frequency.

Title: Improved process for the production of nitrogen-oxygen compounds
IPC: C01B21/20
Filed: 1930-02-06
Abstract: <PICT:0354736/III/1> Nitrogen - oxygen compounds such as nitric acid are produced by passing gases containing nitrogen and oxygen, for example air, through the electric field produced between solid electrodes by a current having a frequency substantially exceeding 100,000 and a tension exceeding 50000 volts.  Catalytic substances such as copper may be placed in the field and may act as intermediate electrodes.  Gases enter the apparatus, which is made of porcelain, at a, the reaction products leaving at b.  A perforated metal sheet c is connected to a high frequency generator, a second sheet d constituting the earth electrode.  An intermediate electrode e consists of a sieve of catalytic metal or is coated therewith. According to an example, if moist air is led through at a velocity of 10 cm. 1 sec. and the field set up between the electrodes c, d is adjusted to 200,000 volts and 800,000 frequency, 105 grams of nitrogen are combined per cubic metre. The use of currents having a frequency of 20000 to 100,000 at a tension of 30000 to 150,000 volts, water constituting at least one electrode, is stated to be known. The Specification as open to inspection under Sect. 91 (3) (a) states that the reaction gases are led through the electric field produced in an adjustable circuit of high frequency oscillations of very high, arbitrarily changeable, tension, and is not restricted to magnitudes of the above order or to the use of solid electrodes.  This subject-matter does not appear in the Specification as accepted.

Patent GB-1099419-A (GB)
Title: Modified epoxide resin esters
IPC: C01B25/22
Filed: 1965-02-03
Abstract: Steel panels which may have been pre-treated with zinc phosphate are anodically coated by electro-phoresis from an aqueous solution comprising an amine salt of an adduct of maleic anhydride and an epoxide ester resin formed by esterifying a diglycidyl ether of a dihydric phenol, with an unsaturated acid derived from a fatty oil, e.g. castor, tall or linseed oil, and optionally also a saturated or aromatic acid.  Prior to esterification, the epoxide resin may itself be treated with a monohydric phenol to form a partial ether. If desired a drying or semi-drying oil, e.g. soya bean, linseed, tall, sunflower, safflower or dehydrated castor oil, or an unsaturated hydrocarbon resin or a copolymer thereof e.g. dicyclopentadiene-isoprene copolymer, may be included in the adduct. The aqueous coating compositions may also contain pigments, organic solvents and aminoplasts e.g. methylated methylol melamine resin. The coatings are cured by baking.ALSO:Heat curable adducts are produced by substantially fully esterifying an epoxy resin which is a diglycidyl ether of a dihydric phenol and has a molecular weight below 700 or an ether thereof with a phenol, with an unsaturated acid having 11 to 24 carbon atoms in the molecule and derived from a fatty oil, possibly together with a saturated or aromatic acid, and reacting the ester so produced with sufficient maleic anhydride to obtain without gel formation an adduct containing at least 5 wt. per cent of combined maleic anhydride.  The adducts may be modified by the presence during the addition of drying or semi-drying oils, unsaturated hydrocarbon resins and copolymers thereof. The adducts may be rendered water reducible by reaction with an amine in water, possibly after preliminary hydrolysis of the anhydride groups.  The aqueous solutions of the amine salts of the adducts may contain water-soluble aminoplasts, pigments and organic solvents and are useful as coating compositions.ALSO:Coatings on substrate, such as zinc phosphate treated steel panels, are formed by applying a composition which is an aqueous solution comprising an amine salt of an adduct of maleic anhydride, together, if desired, with a drying or semi-drying oil or an unsaturated hydrocarbon resin or a copolymer thereof and an ester of a diglycidyl ether of a dihydric phenol, or a partial ether thereof with a phenol, and an unsaturated acid together, if desired, with a saturated or aromatic acid (see Division C3) and curing the coating by baking.  The aqueous compositions may also contain pigments, organic solvents and aminoplasts.  Specified methods of applying the compositions are spraying, brushing, dipping and roller coating.
