Title: Improvements in or relating to apparatus for detecting over-heating of running or braking members in railway rolling stock
IPC: B61K9/06
Filed: 1956-09-10
Abstract: 836,721. Electric temperature alarm systems. TELECOMMUNICATIONS RADIOELECTRIQUES ET TELEPHONIQUES T.R.T. S.A. Sept. 10, 1956 [Sept. 13, 1955; Feb. 3, 1956], No. 27612/56. Class 118 (1). [Also in Groups XXX and XL (b)] Apparatus for detecting overheated axle bearings &c. in a moving railway train comprises a central station CR, Fig. 1, and a plurality of substations ED spaced along the track, each substation including an infra-red detector A, A<1>, Fig. 6, one on each side of the track, and a light source B1 for producing a beam of light directed across the track on to a photo-electric cell Rc, the pulses in the photo-cell Rc due to the passage of the wheels being amplified at Ac and then transmitted along a conductor b to a counter Cb at the central station which counts the number of wheels on a train passing through a substation, the counter Cb being arranged to stop counting when the passage of a hot axle produces a pulse in one of the two infra-red detectors A, A<1>, to signal the occurrence of a hot axle at the wheel indicated by the reading at which the counter Cb has been stopped. A pulse in one of the detectors A, A<1>, due to a hot axle actuates an alarm in the central station CR. Each infra-red detector is associated with a corresponding amplifier and gate Ab and time switch Ca. In the exemplified embodiment the pulses from the infra-red detector A are amplified at A1 and are fed to the central station CR via a gate Rb which is opened by pulses from the photo-cell amplifier Ac to prevent the transmission through the gate of pulses arising from heat sources other than hot axle bearings. The pulse passed through the gate Rb as amplified at A2, A3 and is applied to an alarm time switch Ca, the output of which comprises a D.C. signal of a duration which is characteristic of the particular time switch Ca and differs from the duration of the D.C. signal produced by the time switches corresponding to the infra-red detector A<1> on the other side of the track and to the infra-red detectors in other substations. The D.C. signal from the time switch Ca controls the operation of a stepping relay in the alarm receiver Ra which causes an appropriate one on a series of lamps to be illuminated whereby the substation and side of the track at which the hot bearing is detected are indicated. The signal from the time switch Ca also causes the counter Cb to stop counting. A counter Cf in the central station CR responds to all of the pulses produced in the infra-red detector A, including pulses produced by heat from the biakes, and enables a condition of abnormal braking to be detected. One or more additional counters similar to Cb can be provided in the control station CR to indicate the occurrence and position of second, third, &c., hot axles. The apparatus can also be used to detect a breakage of coupling.

Abstract: 367,820. Thermionic cathodes. ARCTURUS RADIO TUBE CO., 720, Freyling- huysen Avenue, Newark, New Jersey, U.S.A. -(Assignees of Kaul, J. ; 92, Lincoln Place, Irvington, New Jersey, U.S.A.) Sept. 19, 1930, No. 28099. Convention date, Sept. 24, 1929. [Class 39 (i).] A filamentary wire adapted more particularly for use as a heater in the indirectly heated cathode of a thermionic valve is provided with an insulating coating comprising an insulatory metallic oxide in its molecular state, having a high melting-point, and a small percentage of another insulating material having a melting- point lower than that of the metallic oxide. Suitable insulting oxides are those of aluminium, beryllium, magnesium, calcium, chromium, and titanium. To obtain a layer of aluminium oxide in its molecular state upon a tungsten filament a series of successive coatings of a saturated solution of aluminium nitrate containing from 3 to 10 per cent by weight of silicon dioxide are applied thereto, the wire being heated after each coating to break the aluminium nitrate up into aluminium oxide, nitric oxide, and water, the last two being driven off as vapour. The silicon dioxide melts at a temperature below the filament temperature attained during the exhausting of the vacuum tube, thereby causing the aluminium oxide to adhere closely to the wire. Preferably the aluminium nitrate solution is a saturated one having a specific gravity of 1À4 at 27‹ C. Metallic oxides which are good insulators and have a melting-point at or below a dull red heat may be added to the aluminium nitrate solution instead of silicon dioxide.
