Abstract: 367,133. Master control of D.C. motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) Jan. 21, 1931, No. 2073. Convention date, Jan. 21, 1930. Addition to 356,104. [Class 38 (iii).] Non-regenerative braking.-In a multiple-unit train control system, the main controller 37 occupies the same positions for braking as for driving. A reverser 34 is under the control of a switch 45 and a switch 35 connects the motor 12 for driving or braking according to the position of the master controller 30. The controller 30 has three running positions corresponding to the motor with full series resistance, without series resistance and with weakened field, the controller 37 being stepped forward automatically under the control of a relay 36 to exclude the series resistance. When the master controller 30 is moved to the braking positions, the switch 35 changes the motor circuit to a braking circuit starting with weakened field and full series resistance, thereafter the controller 37 is returned in steps in accordance with the displacement of the master controller so as to strengthen the field and then exclude series resistance. By using certain tappings of the resistance for accelerating and others for braking, the same resistance can be used with the correct graduation thereof for both functions. Some of the tappings are common to both functions.

Abstract: 872,898. Dispensing measured quantities by volume. HALL, J., and HALL, C. April 20, 1960 [Jan. 21, 1959], No. 2254/59. Class 106(5) A dispenser comprises a rotatable hopper 11, one or more measuring compartments 12 secured to the hopper, and means to rotate the hopper first in one direction to charge the compartments under the action of gravity and subsequently in the reverse direction to discharge them, valves 17 in the compartments being opened at a suitable point in the motion of the hopper 11 in the discharge direction. The hopper 11, which has a filling opening 11a, is mounted on a frame 13 for rotation about an axis so displaced from the axis of the cylinder that the hopper will return to its initial position after it has been rotated into charging position. Rotation of the hopper is effected by a handle 28 on a cross-rod 24 which is rotatably mounted in the frame 13 and is connected by linkage 26 with the hopper. Each measuring compartment 12 is in the form of a cylinder 12a connected to the hopper by a neck 15 through which the compartment is charged. Mounted axially in the cylinder is a valve rod 17 carrying a valve disc 17a controlling the outlet 12b<SP>1</SP> and normally biased to closed position by a spring 18. A closed cylinder 20 may also be mounted on the valve rod 17 to vary the capacity of the measuring compartment. The upper end of each valve rod 17 carries an abutment 17b adapted to contact a stop 25 mounted on a bar 22 extending across the frame 13 when the hopper is brought into the discharge position. In operation, the handle 28 is moved upwards to rotate the hopper 11 to a position in which the measuring compartments 12 are filled by gravity, and on pulling the handle downwards the hopper is rotated in reverse direction, the valve rods 17 then being depressed by the stops 25 to allow the contained material in the compartments to be discharged. A stop 29 contacts the linkage 26 to limit the return movement of the hopper. If desired, the compartments 12 may be disposed inside the hopper.

Abstract: 555,579. Colour filters. WILLIAMSON, S., and CHILTON, L. V. Feb. 24, 1942, No. 2393. [Class 97 (i)] A colour filter system, which may be used when printing on variable-contrast photographic materials such as are described in Specifications 494,088, 547,060, and 547,883, or for theatrical lighting, or for illuminated advertisement signs, consists of similar parallel-sided co-planar strip filter elements having their long edges in contact or only slightly overlapping, the elements being disposed to cover an aperture through which light is to pass, each element having colour transmission characteristics which vary continuously or in steps between two extremes of different colour from one end of the strip to the other, and each being reversed in colour disposition relative to the next adjacent element, with means for moving alternate elements in unison in a direction parallel to their length relatively to the remaining elements so as to vary the colour characteristics of the light transmitted through the aperture. The light transmited may be integrated by passage through a diffusing screen and an internally-whitened enclosure, and its overall intensity may be controlled by shutter devices. The system shown in Fig. 2 comprises superimposed films 5, 6 secured to pairs of rollers 7, 8 and 9, 10 geared together so that the films may be displaced in opposite directions across a rectangular light aperture 19. Film 5 comprises transparent uncoloured strips 16, 18, Fig. 3, alternating with coloured strips 15, 17, each coloured strip comprising areas A, B differently coloured, say blue and yellow respectively ; or the strips may vary lengthwise continuously or in steps from blue to yellow. Film 6 is identical with film 5 but is reversed, so that i's coloured strips are superimposed on the uncoloured strips of film 5, and the end of film 6 coloured blue lies adjacent to the end of film 5 coloured yellow. In a modification, the films 5, 6 are replaced by concentrically-mounted discs geared to turn in opposite senses, and having similar coloured and uncoloured juxtaposed arcuate strips movable across a sectorial aperture. Overall light intensity may be controlled in the first-described form as by one or more rectangular masking plates movable from the sides of the aperture 19 in a direction perpendicular to the direction of motion of the films 5, 6 ; or by a louvre form of shutter ; or by superimposed light-polarizing sheets. In the second-described form, the light intensity may be. controlled by an iris diaphragm concentric with the filter elements. Specification 538,990 also is referred to.
