Title: Improvements in or relating to the control of trains
IPC: B60L3/00
Filed: 1922-04-20
Abstract: 202,903. Angus, A. R. April 20, 1922. Electrical systems, non-automatic; track apparatus actuating signals on trains and for stopping trains.-Train-carried apparatus giving warning signals and stopping the train is energized from the track rails by currents of different strength according to the condition of the track ahead. Currents for different directions of travel along the track may differ in direction or frequency and the supply of this current is controlled by polarized track relays under control of the signalman. Fig. 3 shows one arrangement of track circuits for co-action with the train apparatus shown in Fig. 4. By operation of the hand switch 503, current of the required polarity from battery 500 is supplied through reactance joints to each section I, II, III and the two polarized relays connected thereto. If the sections II. III are clear the two relays shunt out the resistance 629 in section III and connect through contacts 618, 621, the generator 702 to the track rails of section I; thus a train on section I receives by induction in the coil 360, or by conduction from two brushes spaced apart on one track rail, currant of normal strength by which the arm 926 on the tram-instrument 923 is moved so as to closethe circuit to the magnets 310, 324 to restrain both warning and stopping operations. If section III is occupied the resistance 629 is included in the track circuits and the current supplied to the train is sufficient only to move the arm 926 to a position to restrain the stopping operation and a warning signal is given. If section II is occupied, no current passes to the train and a stopping operation results. The instruments 923, 940 respond to the different frequencies supplied from generators 702, 802, for different directions of running and are included in the train circuit by a switch 400. The generators 702, 703, may be replaced by a D.C. generator connacted through a reversing switch to the track rails, the engine instrument being correspondingly replaced by a polarized device connected to a reversing switch. Specification 190,503 is referred to.

Title: Process for the manufacture of vulcanised fibre
IPC: D21H17/66
Filed: 1929-11-13
Abstract: Vulcanized fibre of a predetermined density is prepared by the application to the fibre of a zinc chloride lye containing a small amount of another salt, preferably an alkaline earth salt such as calcium chloride, the addition of which has a marked effect on the density of the product.  Sodium chloride exerts a less effect than ammonium chloride, and this again much less than calcium chloride, but too high a concentration of calcium chloride causes a decrease in the adherence of the individual layers.  Example: zinc chloride lye of specific gravity 1,975 containing 1,5 per cent of calcium chloride, and used at 60 DEG  C. gives a hard horn-like fibre of specific gravity 1,4, while lye of specific gravity 1,980 containing 0,6 per cent of calcium chloride and used at 60 DEG  C. gives a tough fibre of specific gravity 1,25, and lye of specific gravity 1,975 containing 3 per cent of ammonium chloride and used at 55 DEG  C. gives a light flexible fibre of specific gravity 1,2.

In a wide range temperature compensated expanded scale A.C. measuring circuit the test voltage is applied to an attenuator (Fig. 1, not shown), which may comprise a complex impedance network adapted to remove unwanted harmonics, having a temperature coefficient such as to compensate for temperature variation errors in the remaining apparatus, to feed a rectifier followed by a filter removing the A.C. component and producing a unidirectional voltage proportional to the average or peak value of the test voltage according to the filter time constant. This voltage is applied over a second attentuator (which may be omitted) to a zero suppression circuit comprising a non- linear bridge or a subtraction network comparing the filtered rectifier output with a stabilized reference voltage to produce an output current r=K(E in -X), where E in  is the test voltage, K is a constant, and X is the test voltage value corresponding to zero indication; which deflects an indicating or recording instrument compensated for temperature variation by a series thermistor. In Fig. 2, the test voltage 9 is applied over range switchable attenuating resistance 10 to a diode bridge rectifier; the resistance value being large compared with the forward diode resistance to reduce the effect of temperature variations on the rectifier output, which is smoothed by capacitor 15 to a value proportional to the average of the test input. The second attenuator is omitted and the smoothed voltage is applied to a bridge comprising resistors 16, 17, 18 and Zener diode 19 functioning as a non- linear resistor, whose output represents the required suppressed zero function of the test input due to balance of the bridge for a particular input value and progressive unbalance at other values, and is applied to a D.C. meter 20 in series with a temperature compensating resistor 21.
