Patent GB-190411077-A (GB)
Title: Improvements in and relating to Railway or Tramway Signalling Systems
Filed: 1904-05-13
Granted: 1905-04-06
Abstract: 11,077. British Thomson-Houston Co., [General Electric Co.]. May 13. Signalling and communicating between trains; controlling signals. - In an electric signalling- system, a special relay is used to prevent the signal from returning momentarily to " danger " when the section next but one ahead is cleared. Three sections A, A' A<2> are shown in the Figure, with their signals. A train on section A shortcircuits the relays E, F, and the signals H, D on section A are put at "danger automatically. The home signal H moves the reversing-switch S. Current passes from battery b and energizes the relays E', F<1>. The relay E<1> is not polarized and holds its armature e', which completes the circuit to the operating-mechanism m<1> of the signal H<1>. The relay F<1> is polarized and is arranged so as not to draw its armature f when the signal H is at "danger." When the train leaves section A, the relay E draws its armature, and the signal H is set "clear" and reverses the switch S and therefore the current in the relays E', F'. The relay F<1> draws its armature and sets the signal D<1> at "clear" by means of the mechanism n<1>. The relay E<1>, when the current is reversed, still holds its armature e', and the signal H<1> is set at "clear," but, during the reversal, the energizing-current is momentarily reduced to zero and an ordinary relay would drop its armature and draw it again. This would allow the signal H to come to danger and return. To avoid this, the relay core E is made of such a shape as to form two magnetic circuits, and has three coils on it as shown. The coil i is the energizing-coil. The coin j is wound so as to have induced in it, when the current in the coil i is altered, an electromotive - force which sends a current through the coil k and magnetizes the core E and keeps the armature e in contact with the core during reversal of the main current, and so keeps the signal H stationary when the home signal ahead comes to " clear."

Granted: 1905-06-29
Abstract: 16,468. Brooks, A. A., and Watson, G. A. J uly 26. Photometers.- An exposure meter, for estimating the necessary exposure for a photograph, consists of a lens wit h a variable diaphragm which projects the image on to a screen, and a lens or merely an observation opening through which this image is examined. The aperture of the diaphragm is varied until standard illumination is obtained. Scales are provided on the case of the instrument for calculating the necessary exposure. Fig. 5 is a longitudinal section of the instrument showing the lens 12 which projects the image of the object to be photographed on to the screen 4. The ring 6 contains the iris diaphragm, and is attached to the millededged plate 9, which carries a pointer moving over a scale on the case, so that as the plate 9 is turned the amount of light entering the instrument is varied and a measure of the exposure is given by the pointer on the scale. The diaphragm is opened or closed by means of a pin 17 running in contact with the edge of a cam-opening 15 in a plate attached to the plate 9, being held by springs against the edge and running also in a curved slot. The image on the screen 4 is viewed through the lens 3, which however may be dispensed with and the image viewed directly through the aperture. A moving scale 19 may be added, carrying scales of stops and plate-speeds. The instrument may be attached to a camera, or used separately as desired. The Provisional Specification also states that actinic paper may be used in conjunction with the apparatus, that the image may be re-inverted by any know means, that the viewing-lens may be mounted telescopically, and that the diaphragm may be used in front of the projecting-lens if desired.

Abstract: 8571. Hilliard, J. D. April 20, 1904, [date applied for under Patents Act, 1901]. Cut-outs; distributing; switches.-Relates to systems of transmission of high-tension currents which can be safely controlled by switches of moderate size. The primaries 9, Fig. 1, of series transformers are placed in two of the conductors from the three-phase alternator 1. The secondaries 10 of the transformers are connected in series with the trip coils-7, 8 of the switches 5, 6. In parallel with the primaries 9 and secondaries 10 are placed fusible or other automatic cut-outs 11, 12. When an excessive overload occurs, the fuse 11 blows, and the current in the primary 9, and consequently that in the secondary 10, are greatly increased, the fuse 12 then blowing and the coil 7 or 8 becoming energized. When the fuse 12 blows, however, the reactance of the primary 9 is greatly increased, the trip.coil being wound for this effect, and the line switch is thus protected. Fig. 2 shows the application of the invention to a system supplied with current from a direct-current generator or single-phase alternator 13. Fuses 18, 21 and trip coils 16, 19 are connected in multiple with a non-inductive resistance 17 and an inductive resistance 20.
