Abstract: 498,198. Charts &c. ROCHE, C. P. V. Oct. 14, 1937, No. 27965. [Class 146 (ii)] Apparatus permitting of ascertaining data relative to the probable location of aircraft in flight over known routes comprises a board or sheet, a distance scale along one edge or side of the board, a time scale carried on a member or members so mounted on the board that the scale can be moved relatively to the board, and which is disposed along another edge of the board at right-angles to the distance scale so that the two scales have a common origin, a number of cords or the like, and means for holding in a tautened condition each of the cords between any two points on the board so as to indicate graphically relatively to the two scales the flight of an aircraft along its route. The board 1 may be similar to an ordinary drawing board, and may be provided with an intermediate cork linoleum layer, and a top layer of white fabric provided with markings representing rectangular co - ordinates. The upright scale arranged at the left-hand side of the board represents distances of destination airports and schedule reporting points from the home airport, and the horizontal scale is a time scale arranged on a tape 2 mounted on two spool devices 3 secured to the board whereby the scale can be moved according to the time of the day and thus enable a short board to be used. To enable the lieight of aircraft to be recorded at any given time, an intermediate time-scale tape 2x is provided, and the upper part of the left-hand side of the board is provided with a height scale. The displacementtime curve of each aircraft is represented by a fine elastic cord 9 provided at each end with a metal tag which serves for the attachment of a pin 11. Identification flags or labels 13 attached to further pins are placed adjacent each cord, and the pins of the flags or plain pins may be used for deflecting the cords intermediately. Instead of the upright distance scale being marked on the board &c., a three-sided rule having three different scales thereon may be pivotally mounted on the board. Also, instead of a movable tape for the horizontal time scale, there may be provided a pivotally mounted five or six-sided rule. In a further modification, the tape time scale is replaced by a slidably mounted rule. Several graph boards may be used in combination, and these boards may be used in combination with boards giving detailed information of a number of routes.

Water discharge means for a steam separator included in a steam line comprises a receiver connected to the separator and having a drain valve operable by a servomotor responsive to pressure changes in an orifice chamber connected thereto, the orifice chamber being also connected to the receiver through one throttling orifice and to a low-pressure space, e.g. the atmosphere, through another throttling orifice. As fitted to a locomotive, the steam separator 1, Fig. 1, disposed between the boiler and a superheater is connected by a pipe 4 to a receiver 5 having a separator chamber 6, Fig. 4, and mounting a drain valve 8 connected by a pipe 9 to the receiver and a pipe 28 to the separator chamber. The drain valve comprises a valve member 11, Fig. 7, connected by a stem 13 to a servomotor piston 20 urged upwardly by a spring 18 and subjected on its upper face to the pressure in an orifice chamber 22, Fig. 5, mounted on the receiver. The chamber 22 has arestricted orifice 23, Fig. 6, connected to atmosphere, and a restricted orifice 24 connected to the receiver by a spigot 25. Water from the separator 1 and entrapped steam passes down the pipe 4 to the receiver 5, the steam rising to the top and escaping through the orifices 24, 23, a pipe 26, the chamber 6 and a baffle 32 either directly to atmosphere through a pipe 31a or indirectly through a pipe 31 and the locomotive blower valve 33. On the level of the water in the receiver reaching the orifice chamber, the latter will be flooded and the increased pressure therein transmitted to act on the servomotor piston to open the valve 11 against the spring 18, water draining away through the pipe 28, the chamber 6, which it enters tangentially to separate out any further steam or vapour, and a discharge pipe 30 on to the track or, alternatively, to the feed water tank of the locomotive. The closing of the valve 11 may be delayed by a dashpot in order to ensure an ample discharge of water from the receiver.
