Abstract: 449,950. Microphones. PADDLE, L. H., 92, Lancaster Road, West Norwood, London. Jan. 2, 1935, No. 136. [Class 40 (iv)] In a microphone of the transverse current type, the effective portion of the layer of granular material is disposed in a groove of which substantially all variation in width is gradual and progressive and is accompanied by gradual and progressive variation in depth in the same sense. Alternatively, the groove may be such that all variation in depth is gradual and progressive and is accompanied by uniform width. The carbon granules are contained in a groove 11 formed in the front surface of an insulating block 10 and closed by a diaphragm 12 clamped to the block by a plate 13 having an opening corresponding to the shape of the groove 11. The groove increases in depth towards the electrodes 19 sunk in grooves in the body 10 and secured by screws 20 to rods 21 on which are mounted terminals 24, which may be held against rotation by pins 25. As shown in Fig. 4, the shape of the groove 11 may vary so that its greatest width occurs where its depth is a maximum and so that its width at the centre is a minimum. The effective depth and/or width of the groove 11 may be varied by a member operated from the outside of the casing. The front of the microphone is covered by a fretted plate and an interposed layer of fabric (not shown).

Title: Improvements relating to electric ignition systems for internal combustion engines
IPC: F02P3/08
Filed: 1945-01-05
Abstract: 587,338. Ignition systems. LUCAS, Ltd., J., and LAIRD, J. A. Jan. 5, 1945, No. 503. [Class 7 (iv)] In an ignition system of the type having a main condenser d charged by an electromagnetic source and discharged through the primary of a transformer the secondary of which is connected to a sparking plug or plugs the charging of the condenser takes place through a charging gap e and discharge is effected by a three electrode discharging gap j having connected to its middle electrode a second condenser k the other side of which is connected to a point between the charging gap and the source. In the arrangement shown a magneto charges the main condenser d through the gap e and the second condenser k through the lower half of the gap j which lower half has a breakdown voltage of about one half the voltage to which the main condenser is charged. The breakdown voltage of the upper half of the gap j is greater than the voltage to which the condenser is charged. When the charging of the two condensers ceases the two gaps isolate the condensers from the magneto. While the voltage of the magneto is falling the voltage across the gap j due to the combined effects of the condensers d, k is sufficient to cause breakdown of the upper half of the gap and consequent discharge of the condenser through the primary winding f. The transformer secondary may be connected to the sparking plugs through a distributor or there may be a separate transformer for each sparking plug connected to the condenser circuit through the distributor. Specification 529,558 is referred to.
