Title: Improvements in and relating to photographic apparatus for taking photographs on lenticular films
IPC: G03B33/10
Filed: 1936-03-18
Abstract: 454,357. Filters for colour photography. OPTICOLOR AKT.-GES., Glarus, Switzerland. March 18, 1936, No. 8145. Convention date, March 19, 1935. [Class 98 (ii)] To avoid the formation of colour fringes on distant objects when photographing on lenticular films, the colour filter is subdivided into zones in two directions so that zones of all the colours are located adjacent to one another in each direction. For a three colour filter for use with films having spherical lenticles, an arrangement of three lines and three columns is used, each line and column having a red, a green, and a blue zone as shown in Fig. 6. In the case of films with cylindrical lenticles the arrangement shown in Fig. 1 is used. The filter 2 consists of five bands coloured blue, green, red, blue, green in the usual manner. In front of one third of this filter pairs of parallel reflectors 4, 4<1>, 5, 5<1>, 6, 61 are arranged so that light from the object which would normally fall on the bands g, r, b falls in this third of the area on the bands b<1>, g, r. A similar system displacing the light in the reverse direction covers another third of the filter. Arrangements in which the filter. is associated with a greater number of sets of reflectors are also described.

Filed: 1937-03-19
Abstract: 487,084. Screw propellers. UNITED AIRCRAFT CORPORATION. March 19, 1937, No. 8157. Convention date, March 26, 1936. [Class 114] A variable-pitch screw propeller in which the blades are carried by spider arms and held in a hub barrel, are controlled as regards pitch by members inside the barrel and inside a front hydraulic cylinder mounted on the hub. The propeller shaft 14 carries an extension 72 having a hexagonal flange 74 contiguous to the hexagonal nut on the end of a hollow member 42 which is screwed to the shaft at 20, and which holds the conical members 36, 38 which clamp the hub in position. The two hexagonal faces are held in locked engagement by an encircling member 78. Upon this central tube 72 is adapted to slide a piston 82 which is contained within a cylinder 64 screwed to the propeller hub at 60. The piston has, on its extended faces, two curved depressions 88, in which engage the bent ends of arms 92 which are secured to the blade root. The blades tend to set themselves under external forces in the low pitch position and are moved to high pitch position by the piston 82. In order that the piston shall not turn on its axis under the reaction imparted to the arms 92, it is provided with side recesses which move over pins 110, fitted to segmental sleeves 108 in the cylinder. These recesses 110, normally straight, may be given a curve opposite to that in the recesses 88. Within the recess 110 are screwed rods 136 carrying nuts 142 which, by contact with fixed side projections, limit the upper and lower pitch position settings. The arms 92 are secured to the blade root through a ring 104 which has inner and outer teeth of differing number to provide a vernier adjustment. The supply of pressure oil to the cylinder may be controlled by a centrifugal governor, in which case the governor 120 controls a valve 126 in a passage 124 leading to the hollow crankshaft ; the setting of the governor being controlled by hand-lever 134. In a modification, instead of the piston moving along the pins 110, it may be provided with a series of balls on either side of the depressions, whereby tilt of the piston is catered for. In a further arrangement, the space in the centre of the crankshaft is provided with vents and is thus adapted for acting as a crankcase breather when the lubricating pump of the engine is used as the source of power liquid for operating the piston.
