[Class 40 (v)] An aerial for a motor-car or aeroplane consists of a U-shaped dipole, broadly tuned to the frequency at which the most serious ignition interference occurs. The aerial, which may be coated with rubber or enamel, is adjustable in overall length, and also as regards its distance from the chassis. Fig. 1 shows the aerial comprising two U-shaped limbs 33 mounted on adjustable brackets 29 under the running-board 21. Its length is adjusted by means of the trombone joint 31, 33, shown in Fig. 3, so that ignition interference sets up standing-waves with a voltage node at the centre, where the lead 9 to the set is taken. Fig. 14 shows the screened lead-in conductors 9, 11, feeding the primary coil 15 of the input coupling. The screen 6 is bonded to the casing of the set 7 which, in turn, is earthed at 4 to the chassis. The earth-lead from the coil 15 is bonded to the chassis at a point 2 remote from the set 7, so as to divert the circulating currents from the ignition system S as shown by the arrows. The aerial is mounted about four inches below the running-board so as to increase the signal voltage transferred to the set, and the cross-section of the aerial wires is preferably #". Fig. 16 shows a complete installation, including the aerial X35, lead-in X21, and the input circuit to the first stage of a superhet set. The lead-in shield is grounded to the chassis, near the point X29 where the aerial lead from the set is similarly earthed. The input and aerial circuit forms a substantially-fixed band-pass filter which attenuates interfering frequencies outside the tuning range, whilst giving a uniform voltage-gain inside that range.

Abstract: 344,022. Multiplex telegraphy. WESTERN UNION TELEGRAPH CO., 195, Broadway, New York, U.S.A. Nov. 28, 1929, No. 36460. Convention date, Nov. 5. [Class 40 (iii).] In a system in which signals from two or more cables 10, 10A are repeated into a single highspeed line 11, errors due to phase difference between the incoming channels are eliminated by apparatus comprising a distributor 15, 15A for each incoming channel and a common outgoing distributor 18. Thus the incoming cables 10, 10A feed, through the relays shown, their respective distributors 15, 15A. Each of these distributors has two sets of contacts 1, 2, 3 .. and 1A, 2A, 3A, .. which can be picked out by the oppositely set switches 49, 49A. Thus, the switch 49 being set to the left, the contacts 1A, 2A, 3A .. of ring 15 are ineffective, since the output circuit 46, 45 of the relay 40 controlled through these contacts is broken at 45. For this channel, therefore, only the contacts 1, 2, 3 .. are effective to pass on received signals to the odd contacts 1, 2, 3 .. of the retransmitting ring 18. On the other hand, since the switch 49A is set to the right, the contacts 1, 2, 3 .. of ring 15A are ineffective, the output circuit of the relay 39A controlled thereby being cut off at 44A ; while contacts 1A, 2A, 3A .. of ring 15A are effective, since the relay 40A controlled thereby is able to pass on signals to the even contacts 1A, 2A, 3A .. of the retransmitting ring 18. Thus, whether or not there is a phase difference between the incoming channels 10, 10A, the signals from the channel 10 are, with the switches 49, 49A set as shown, passed on the outgoing line 11 through the channelling relay 51 via the segments 1, 2, 3 .. of the ring 18, while the signals from the channel 10A are passed on through the remaining segments 1A, 2A, 3A .., the impulses being thus separated into two channels in the outgoing line 11. Synchronizing. The distributors are all driven at the same speed, and each incoming channel 10 or 10A controls a common synchronizing magnet 62 through a distributor 24 or 24A individual to the channel, the signals supplied to the retransmitting distributor 18 being shunted through synchronizing relays 55, 55A. When the armature 57, for instance, is moved to the right, by a negative signal the condenser 59 acquires a charge either through an effective segment 1, 2, 3 .. of the ring 24 and through the correcting magnet 62, in which case a correction is effected, or (if the brush 26 is not on an effective segment at the moment when a negative signal arrives) through an ineffective segment and resistance 63, so that no correction is effected in this case. On the reception of a positive impulse the armature 57 moves to the left and discharges the condenser. Similar functions are performed in the second incoming channel by the synchronizing relay 55A and distributor 24A, so that synchronism is maintained even when one channel is idle.

Abstract: 960,898. Controlling burners. COMPAGNIO DES GAZ DE PETROLE PRIMAGAZ. Oct. 11, 1961 [Oct. 25, 1960; Feb. 22, 1961], No. 36549/61. Heading F4T. [Also in Division F2] A double valve, Fig. 1, for controlling the supply of propane and the delayed supply of liquid fuel to a burner comprises a valve 13 fixed on one end of a stem 9 secured to an elastic diaphragm 5 and a second valve 20 slidable on the other end of the stem 9. The first valve 13 controls the flow of propane from an inlet 16 to an outlet 17. The second valve 20 controls the flow of liquid fuel from an inlet 22 to an outlet 23. Both valves are closed by springs. The upper surface of the diaphragm is subjected to the pressure of the propane via an inlet 6 and its under surface is at atmospheric pressure via an aperture 8. When the stem 9 descends it immediately opens the valve 13 to supply propane to the burner and its lower end slides in the valve 20 until a shoulder 25 engages the valve 20 and opens it to supply liquid fuel to the burner. The burner control system shown in Fig. 2 comprises a burner 31, a liquid fuel pipe 32, a high pressure propane pipe 34 and a valve 43 similar to that described above. The valve is actuated by low pressure propane supplied through a pressure reducing valve 36 and a pipe 42 and controlled by two valves 38, 39 in series, the valve 38 also controlling a pilot light 40 and the valve 39 being responsive to a thermostat 41. When either valve 38 or 39 closes, the propane in the pipe 42 escapes through a microburner 46.
