Abstract: 605,486. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34565. Convention date, March 13, 1943. [Class 97 (i)] A range-finder includes adjustment coincident marks, for example a coincidence line on a movable member, an image of which is projected by the whole or part of the rangefinder system adjacent a fiducial mark, the movable member being coupled to the ranging adjuster so that non-coincidence of the fiducial mark and the image of the line indicates lack of adjustment of the finder. The invention may be applied to coincidence or stereoscopic finders. Fig. 3 shows a finder of the type described in Specification 605,482, in which superimposed images reflected by mirrors 11, and semi-transparent mirror 12, are formed in the plane 15 of an eye-piece 16 by lens 13 and erecting prism 60. Coincidence is effected by rotation of mirrors 11 by arm 51 engaging a cam 53 on a rotatable shaft 54 carrying disc 55 with a spiral coincidence line 56. The line is illuminated by lamp 57, light from which passes into the erecting prism 60 and after passage through objective 13, reflection at prism surface 25 and dove prism 26 attached respectively to mirrors 11, 12, forms an image 21<1> of the line adjacent fiducial marks 30 in the plane 15, Fig. 1A. Maladjustment of the instrument is indicated by lack of coincidence of the image 21<1> and marks 30, which may be corrected by slight rotation of the mirror 12 by screws 44, 45, as described in Specifications 602,920. A modification in which the shaft 54 is horizontal is described. In the stereofinder shown in Fig. 4, end prisms 70 and objectives 71 form images in plane 72, 73 rotatable wedges operated by varying knob 84 effecting stereo coincidence of these images with marks 81, 82. A hollow cylinder 91, rotated simultaneously by knob 84 contains a lamp and carries a spiral coincidence line on its periphery an image 90<1> of this line, being formed adjacent fiducial marks 95 in the plane 73 by objectives 71, end prisms 70 and subsidiary prisms 92, 93, as described in Specification 605,481.

Abstract: 467,914. Telephone sets. STANDARD TELEPHONES & CABLES, Ltd., ROBERTON, J. S. P., and POWELL, F. G. S. Dec. 24, 1935, No. 35753. [Class 40 (iv)] A support or stand for a telephone-type impulse dial is provided with locking means associated with a substantially circular dial seating and so arranged that the dial is inserted into its seating by axial movement and is locked in position without subsequent rotary movement of the dial on its axis in its seating. As shown in Figs. 1, 2, the hole 2 in the casing 1 is formed with three equally-spaced grooves 11. Beneath the hole is mount d a metal plate 3 provided with three equally spaced grooves 10 and attached to the casing by three screws 4 located in slots in the ring which is connected to the screws by springs 6. A downwardly inclined projection 7 on the ring is engaged by a tool 9 to rotate the ring 3 and to bring the grooves 10, 11 into alignment. After the insertion of the dial casing, the withdrawal of the tool allows the ring 3 to rotate so that it engages above lugs on arms attached to the dial casing. The dial is removed by the insertion of the tool 9 into the hole 8 to bring the grooves 10, 11 into their aligned positions. In a modification, Figs. 3 to 6 (not shown), the dial seating is formed with a single groove in which is located the end portion of a pivoted detent. The dial aperture is slightly oversize so that the dial can be passed partially within the aperture by tilting. It is then rocked in the reverse direction and the detent, after having been rotated to allow the passage of a lug on the dial, snaps over its upper surface to lock the dial in position. The dial is withdrawn after the pivoted detent has been rotated out of engagement with the lug by a tool inserted from the outside of the casing. In a further modification, Fig. 7, a ring 23 mounted on the lugs OL1, OL2, OL3 carries one or more inclined spring lugs 25 and a U-shaped detent 24. The underside of the dial seating is formed with one or more recesses 28 corresponding to the lugs 25, and a groove 21 having an undercut edge 22. The aperture is slightly oversize and the dial, after having been tilted so that the lugs 25 engage in the recesses 28, is rocked in the reverse direction until the end of the detent 24 snaps into the undercut portion 22 to lock the dial in position. The detent 24 is released for the withdrawal of the dial by a tool 27 passed down an inclined hole 26.
