Abstract: 628,157. Ignition magnetos. DEBENHAM, W. R., and MITCHELL, A. H. March 31, 1947, No. 8637. [Class 35] [Also in Group XXVII] In a high-frequency ignition-apparatus' in which a condenser connected with the output of a magneto discharges through a spark-gap to excite the primary winding of a highfrequency transformer interposed between the magneto and a spark-plug lead, there is provided means, which when operative would reduce the maximum voltage to which the magneto could charge the condenser, if the spark gap were disconnected, they are controlled by a speedresponsive device so as to be made operative as and when the magneto reaches a speed just below that at which said voltage would exceed the break-down voltage of the spark-gap to a substantial extent. A resistor 11, Fig. 1, is in series with the magneto secondary-winding 12, the primary of which is in the charging circuit of the condenser 16. Across the latter is connected an enclosed spark-gap 17 in series with the primary 18 of the high-frequency transformer, whilst a spark plug 20 is in circuit with the secondary 19 of the transformer. The speed-responsive device 21 controls a switch 22 which is operated at about 1500 r.p.m., to put in circuit the resistance 11. In a modification, the resistance is connected in parallel with the magneto as indicated at 11a. The resistors and switches may be replaced by a number of seriesconnected resistors and a multiway switch or a continuously-variable resistor. In another modification, Fig. 2, which may be used separately or in addition to the above embodiments, a speed-responsive device 35 increases the reluctance of the magnetic circuit of the magneto, at an approximate speed of 2750 r.p.m., by a progressive or one-step bridging of an air-gap 32, therefore reducing the flux associated with the magneto coil 31. Specification 587,437, (Group XXVII], is referred to. The Provisional Specification describes also how the shunt resistor may be of carbon or made from material known under the Registered Trade Mark of " Metrosil," and has a negative temperature-coefficient, whilst an additional cross-wire series resistance that has a positive temperature-coefficient may be utilized. An impedance may be included in series with the magneto output to prevent brush discharge in the spark-gap, which impedance may constitute a resistance giving the same result as resistances 11 and 11a.
