Title: Improvements in or relating to railway signalling systems
IPC: B61L3/02
Filed: 1922-08-16
Abstract: 203,164. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. Aug. 16, 1922. Track apparatus for stopping trains.-Pulsating or other composite currents are supplied from fixed track ramps through a collecting shoe, which serves also to remove mechanical restraints from the brake valves, to two electromagnetic restraining means which are responsive to different characteristics of the composite current. Fig. 1 shows the traincarried apparatus which comprises a sliding shoe 1 having a collar 3 coacting with collars on the spring pressed rods 6, 7 to remove these from the bell-crank levers 13, 14 which operate the brake valves 10, 11. The bell-cranks 13, 14 carry the armatures of an alternating current electromagnet 12 and a polarized electromagnet 15. The winding of magnet 12 is in the secondary circuit of a transformer 42, the primary of which, in series with the winding 15, is energized from the track ramps through the shoe 1. Fig. 2 shows the circuits to a home signal ramp 53 and a distant signal ramp 36. At a distant signal the vibrator generator 40 is put in action by a train on an insulated rail section 35, and negative pulsating current is supplied, if the signal is at danger, from the battery 46 to the ramp 36 and the train apparatus. Magnet 12 is energized and holds the valve 10 closed. Magnet 15 releases its armature and the valve 11 is opened by the air pressure and the audible signal 17 is sounded and a service application of the brakes is made. If the distant and home signals are clear, positive pulsating current of greater magnitude is supplied from battery 45 over the lever contacts 44, home signal contacts 43 and distant signal contacts 41, this current preventing the opening of the brake valves and sounding the bell 47. At the home signal, a weak positive pulsating current from part of battery 45 over the vibrator 51 and switch 50 is received if the signal is clear, which restrains the brakes but does not operate the bell 47. If the signal is at danger, no current is received and both valves 10, 11 are opened. The valves 10, 11 may be closed by Bowden or similar mechanism. A retarding device, such as a screw movement 62, is fitted on the emergency brake valve resetting mechanism to ensure the prolonged application of the brake sufficient to stop the train. The resetting mechanisms simultaneously open valves 24, 34 while they are in use thereby ensuring their replacement in order to release the brakes. The shoe 1 is hollow and the cavity is connected to the train pipe by ports 29, a chamber formed by flexible diaphragms 27, 28, and conduit 26. Breakage of the shoe, therefore, causes application of the brakes. The shoe is held in its raised position by detents 21 until the valve is re-set. A collar and pin on the valve stem serve to move the detents into and out of operative position.

Abstract: 740,854. Centre! systems for electrostatic precipitators. LODGE-COTTRELL, Ltd. July 28, 1954 [Aug. 13, 1953], No. 22374/53. Drawings to Specification. Class 38 (4). The high tension transformer in the supply circuit of an electrostatic precipitator is fed through an induction regulator, continuously variable auto-transformer, or other motoroperated voltage regulator and means is provided for breaking the motor control circuit at a predetermined value of current or voltage in the primary circuit of the transformer, or in the rectified high-tension supply to the precipitator, so that the precipitator operates under predetermined current or voltage conditions found to be optimum on the site. The means for breaking the motor control circuit may be an adjustable limit switch actuated by a moving member of the voltage regulator when the last attains a certain position in its travel. Alternatively, a current- or voltage-operated relay, or a contact-making ammeter or voltmeter, may be arranged to control the motor circuit. An overload circuit-breaker is provided in the primary circuit of the high-tension transformer and may have an auxiliary contact which, upon closing of the circuit-breaker, causes energization of the voltage control motor in the voltageraising direction until the limit switch operates. The circuit-breaker is associated with means, such as a time delay relay, which is energized upon tripping of the circuit-breaker and is effective to reset the latter after a predetermined interval, subject to over-riding contact by a notching relay, or the equivalent, which locks out the circuit-breaker after a predetermined number of trips. The circuit-breaker may reset if tripping occurs at less than a predetermined rate. An auxiliary circuit-breaker may temporarily insert resistance in the primary circuit of the transformer so as to reduce the voltage applied to the precipitator upon the occurrence of excessive current. Visual or audible alarms may be operated in the.event of a dead short-circuit in the precipitator.

Filed: 1975-08-11
Abstract: 1470636 Encoding binary data INTERNATIONAL BUSINESS MACHINES CORP 11 Aug 1975 [1 Nov 1974] 22872/75 Heading G4C Serial binary input data is encoded into a run length limited code, wherein successive encoded binary ones are separated by no fewer than one binary zero and no more than four binary zeros, each item of input data being encoded into a digit pair of signals. In an embodiment, Fig. 3 (not shown), a data digit 0 is encoded as 00 if the previous data digit was 1 encoded as 01, and 10 otherwise. A data digit 1 is encoded as 10, 00 or 01, depending on the values of the next and previous data digits, and on the value of a backward parity function determined by the number of data digits 0 that were encoded prior to the instant data digit 1, Assuming for example that an input data sequence is 110001110, and that encoding begins at initial state B, the first 1 is encoded as 01 and leads to state E, the next 1 is encoded as 01 and keeps the system in state E, the next 0 is encoded as 00 and leads to state C, the next 0 is encoded as 10 and leads to state B, the next 0 is encoded as 10 and leads to state C, and the next 1 is encoded as 10 and leads to state D (because state C has a lookahead facility whereby the next data digit to the one being considered is examined to determine branching either to state D or to state A according as this next data digit is 1 or 0). Since state D was reached in this case, the next data digit is necessarily 1; this is encoded as 00 and leads to state C. The next 1 is encoded as 01 and leads to state A (since the next data digit is 0), and the final 0 is encoded as 00 and leads back to initial state B. Branches out of states A and D by 1 and 0 respectively are forbidden, because of the lookahead facility of state C. The encoded data is thus (01)(01)(00)(10)(10)(10)(00)(01)(00), which may be recorded on a magnetic disc. An encoder, Fig. 6 (not shown), is described, the encoder comprising a storage register formed of flip-flops (1-3) for storing input data, and AND gates (10, 11, 13, 15) clocked at twice the data frequency for passing the outputs of the flip-flops to an output of the encoder. A decoder is also described having flip-flop storage (16- 20), Fig. 7 (not shown).
