Title: Internal combustion engine ignition systems
IPC: F02P3/04
Filed: 1962-03-08
Abstract: 938,948. Ignition systems. GENERAL MOTORS CORPORATION. March 8, 1962 [March 13, 1961], No. 8933/62. Class 7(4). In an internal-combustion engine ignition system a spark plug is adapted to be energized from a voltage source by an energizing circuit controlled by a first semiconductor switch device which forms part of a charging circuit for a capacitor, a second semi - conductor switch device is operable to connect the first switch device across the capacitor when the second switch device is conductive and a device operating in time with the engine is arranged to vary the conductivity of the second switch device. When the transistor 58 is conductive between collector and emitter there will be a base circuit for transistor 46 by way of resistor 60 and with flow of base current in the transistor 46 the latter will be fully conductive between emitter and collector so that the junction 44 will be changed from earth potential to the positive potential of the battery 88 and accordingly a discharge path for the capacitor 40 is established by way of the emitter to collector circuit of transistor 46. The capacitor discharges by way of a circuit including resistor 38 battery 88 lead wire 34 and the emitter collector circuit of the transistor 46. The voltage appearing across the capacitor 40 will be impressed across the emitter and base of the transistor 32 and the polarity of the voltage on the capacitor 40 is such that the base of the transistor 32 suddenly becomes positive with respect to its emitter thereby rendering the transistor 32 non-conductive between emitter and collector and cutting off current flow to the primary winding 26. The sudden interruption of the current flow through the primary winding 26 causes a large voltage to be induced in the secondary winding 22 and this voltage is applied to a spark plug 12 by way of the distributer 14.

Title: Method of manufacturing boron nitride
Inventor: WOOD ANTHONY ARTHUR ROBINSON
IPC: C01B21/064
Filed: 1958-03-24
Abstract: Boron nitride is prepared by passing nitrogen, gaseous ammonia or another nitrogen-providing gas over a heated intimate mixture comprising as boron providing constituent boric oxide, boric acid or one or more metal borates, carbon and as a catalyst, a metal of Atomic No. 21-30, 39-46, 57 or 58, an alkaline earth metal (inc. Hg) or alkali metal, or a compound of such a metal or a mixture of such metals or compounds.  The reaction is carried out at temperatures generally above 1200 DEG C. particularly in the range 1200-1600 DEG C. but depending upon the catalyst employed.  Preferred catalysts are, or contain as compounds, the metals Mo, Nb, Mn, Cr, Ca, Ba, or Sr.  Catalyst metals of Atomic No. 21-30, 39-46, 57 or 58, are preferably employed in the form of oxides and alkaline earth and alkali metals as the carbonates.  The use of catalyst metals compounded as borates, hydroxides, nitrates, nitrides, acetates, and other organic acid salts is also referred to.  As a modification when the catalyst metal(s) is/are used compounded as borates such borates also form the boron providing constituent of the mixture.  The proportion of catalyst used is dependant upon the specific metal or compound used but is generally 1-10% wt. of the total mixture.  The proportion of other substances employed should be at least stoichiometric with preferably an excess of boron providing constituent over the amount of carbon present.  In order to maintain a constant nitriding rate during reaction the heated intimate mixture may be ground at intervals, or continuously stirred say by heating in a rotating tube. Alternatively the mixture may be employed in an expanded but coherent form say that derived by the addition of an organic binder, e.g. sugar, molasses, starch or another carbohydrate binder, pitch asphalt, tar or another hydrocarbon binder, or be rendered porous by incorporation of a substance, e.g. ammonium chloride, which evolves gas or vapour at the nitriding temperature employed.  In operation the intimate mixture plus a binder, if used, is pasted with water and the paste granulated and contacted with the nitriding atmosphere for several hours.  The product may be leached with dilute hydrochloric acid and the residue washed and dried. Specification 870,083 is referred to.

Filed: 1938-03-28
Abstract: 516,281. Gas producers &c. GRIGGS, A. R. March 28, 1938, No. 9459. [Class 55 (i)] [Also in Group III] In a gas producer the blast is admitted at such high velocity and in such a direction that it tends to uphold the fuel in an open condition, and is rapidly interrupted to set up pulsations imparting settling movements to the fuel and causing ash to fall away from it. In the production of water gas such pulsations may be applied to both the air and steam blasts. The pulsations may be produced by suitable construction of the pump or blower or by the operation of a valve at the inlet or even at the outlet of the producer. The figure shows such a valve in the form of a rotating slotted disc 3 Within a casing 4 surrounding a gap in the conduit 2. Alternatively there may be used a butterfly valve, which may be so shaped that the flow of air will itself rotate it. The Provisional Specification describes also the general application of pulsating gas supply to reactions between solids and gases.

Abstract: 1,164,415. Doppler speed measurement. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. 28 Feb., 1968 [1 March, 1967], No. 9603/68. Heading H4D. Specification describes a system for determining the radial speed of a source of radio pulses with a carrier frequency F 0 , wherein the pulses are too short to enable a direct determination of the received carrier frequency. The v received pulses at frequency F 0  (1 + -) are c heterodyned in mixer 12 to an I.F. of F 0  (1 +   v/c) - F H . and are fed to one input of a frequency c discriminator 15. A variable frequency oscillator 16 feeds the other input of the discriminator and is controlled by the discriminator out-   put such that its frequency is F 0  (1 + v/c) - F H .   A clock oscillator 181 similar and in synchronism with a similar oscillator on the source produces a signal at F 0 . This is fed to one input of mixer 183 and to a 1 : 1/N frequency divider 182, the output of which at F 0 /N is fed to the second   input of mixer 183. The output of mixer 183 is thus at F 0  (1 - l/N) and is heterodyned to   F 0  (1 - l/N) - F H  in mixer 19, and fed to one N input of frequency comparator 21, the other input of which receives the output of oscillator 16. The output of comparator 21 is at fre-   quency F 0  (V/C + l/N) which frequency is meas-   ured at 22 and indicates the source's radial   speed, a frequency >FO/N indicating an approach-     ing source, and a frequency <FO/N indicating a   receding source.
