Title: Improvements in or relating to railway signalling systems
IPC: B61L13/04
Filed: 1922-06-10
Abstract: 198,221. Automatic Telephone Manufacturing Co., Ltd., Hudd, A. E., and Tattersall, A. E. June 10, 1922. Electrical systems, non-automatic; combined electrical and mechanical systems, non-automatic.-A signal can only be set clear if a transient current is sent over the track rails at substantially the same instant as the attempt is made to perform the mechanical operation of lower ing the signal. This current may be transmitted from the far end of a section by a generator controlled from near the operating lever, or bv a contact on that lever. The drawing shows apparatus in its normal position with the track clear. At each end of the section, short insulated rails 1, 2 are connected in series with a battery 10 and relay 3, line wire 34, relay 30 and with battery 17 indicator 8 and relay 31 respectively. Relays 30, 31 are interdependent on one another, and the shunting of either relay by a train entering the section opens the circuit of the other. In order to set the signal M the contact 25 is closed and relay 3 is energized to put the vibrator-magnet 9 in circuit whereby its armature causes alternating current to pass from batteries 39, 40 over the track rails if the track is clear, to transformer 4 and relay 5. Magnets 6, 7 are thereby energized and armatures 32, 33 close the circuit of the lock magnet 20 and, also, if desired, an indicator (not shown). A train passing into the section de-energizes relays 30, 31 and as it passes out again energizes magnet 3 and causes the vibrator generator to pass alternating current over the section after the train has cleared the section. Armatures 13, 14 then close the local circuit through relays 30, 31 from battery 26 thereby restoring the apparatus to normal. Specifications 163,418, 193,671, and 200,267 are referred to.

The induced voltage is rectified and fed to memory devices which store the amplitude values of successive oscillations, followed by a stage wherein the log dec is calculated. The sample is again oscillated and the induced voltage fed to a frequency measuring circuit, where the time taken for a predetermined number of cycles of oscillation is determined, the number of cycles being determined by the value of the log dec, 10 cycles for low values of log dec, 5 cycles for higher values and only one cycle for large values. The frequency signal is squared to give a value representing the torsional modulus. In modifications the log dec and frequency are determined from one set of oscillations.
