Patent GB-399379-A (GB)
IPC: G03C7/14
Abstract: 399,379. Colour photography and kinematography. L E I T Z GES., E., Optical Works, Wetzlar, Germany. Feb. 10, 1933, Nos. 4133, 4134, and 4135. Convention dates, Feb. 17, 1932, June 17, 1932, and Nov. 5, 1932. [Class 98 (ii).] In a method of projecting, or printing by projection, a lenticular colour-record film, employing a projection system wherein the film D, Fig. 1, is placed with its lenticles facing the light-source and the colour-selecting filter C is mounted between the light-source A and the film, the filter, which may be adjustable along the optical axis, comprises a sequence of periodically-recurring colour bands C<1> C<2>, C<3>, which may be separated by intervening spaces, and is so arranged that bands of the same colour are focused by adjoining lenticles of the film on to common strips of the image-layer. The filter corresponds, in size and position relatively to the film, to the virtual image of the filter in the taking camera. In order to avoid dominant hues, an optical condenser system may be used which produces an image of the light-source, or of an intermediate pupil, in the plane of the image-layer of the film ; and a corrugated glass or like surface may be interposed between the light-source and the film to spread the light laterally. To avoid the use of a light-source of large extent, a small source H, Fig. 4, may be used with a wide-aperture short-focus condenser K followed by a longfocus condenser K<1>. A diaphragm L, adjustable in size in accordance with the optical constants of the film and the aperture of the objective, so that, whatever its position in its own plane, the ratio of colour areas of the filter O remains the same and dominants are suppressed, may be introduced in the system in such a position that an image thereof is formed at M near the front principal plane of the objective. Various shapes of diaphragm and methods of adjusting them are illustrated in the Specification. The optical system producing the diaphragm image is preferably achromatic ; if it is non-achromatic, the effective widths of the filter bands are adjusted (as by blacking the interspaces between the bands) in proportion to the magnifications produced by the system in the diaphragm image for the corresponding colours. If the objective is changed for one of different focal length, a cylindrical lens P is introduced between the filter and the film, with its axis at rightangles to the filter bands, to adjust the position of the image to the front principal plane M<1> of the new objective.

[Also in Division B7] Means for applying simultaneously and independently brakes for steering and retardation respectively of a vehicle such as a tractor comprises a pedal which is angularly movable about two axes at right angles to each other. The pedal is movable angularly about one axis for applying the brakes and about the other for causing a force applied to the pedal to be transmitted to the brakes on wheels on either or both sides of the vehicle. In one embodiment, Fig. 1, the pedal 10 is pivoted about a pin 11 in a fork in the outer end of a short shaft 12 which is rotatable about its own axis in a housing 18. Rotation of the pedal about pin 11 actuates through a rod 15 a master cylinder 16 from which fluid pressure flows to a valve 24. Fluid is directed by the valve into one or both of the outlets 25, 26 connected to the slave cylinders on opposite sides of the vehicle. Foot pressure applied in the centre of the pad 27 causes fluid to be directed into both outlets 25, 26 and foot pressure applied to one or other side of the pad actuates the shaft 12 so that a cranked plate 21 bolted to a flange 19 rigid with shaft 12 actuates a rocking spindle 23 of the valve 24 to permit fluid to be directed into one or other of the outlets 25, 26. A locking device which comprises a hand-operated spring-loaded pin which enters into a hole in the flange 19 may be provided for holding the shaft 12 in the position whereby fluid pressure is directed to both outlets 25, 26. In another embodiment, Figs. 3 and 4, foot pressure applied to one or other side of the pad 42 rotates the pedal 41 about the axis of a shaft 44 so that an arm 46 engages with one or other of the slots 52, 53 in members 47, 48 which are connected mechanically or hydraulically to the brakes on opposite sides of the vehicle. The arm 46 is normally in engagement with both slots 52, 53 so as to apply both sets of brakes. Pivotal movement of the pedal about the axis 43 causes the arm 46 to move one or both of the members 47, 48. In a further embodiment, Fig. 8, similar to the last embodiment an arm 61 has a balance bar 62 pivoted to the lower end thereof and normally spaced from parallel walls 66, 67. Links 64, 65 are connected mechanically or hydraulically to the brakes on opposite sides of the vehicle so that when one or other end of the bar 62 is moved into one or other of the slots 68 only the brakes on one side of the vehicle will be operated.
