Abstract: 474,509. Photographic roll - film cameras. LEITZ GES., E. Feb. 11, 1937, No. 4140. Convention date, April 3, 1936. [Class 98 (i)] In a photographic roll-film camera of the kind in which winding mechanism for the film feed and shutter is operated by a spring or other motor through intermediate mechanism part of which alternately rotates or remains stationary, the time of rotation is longer than the stationary time. Spring drums 7, 11, Figs. 1 and 2, wound by a key 32 operate the winding mechanism through a gearing shown in Fig. 3. The toothed wheel 14 engages co-axial mutilated gear wheels 16, 17 connected by a pin 55 engaging a slot 57. The mechanism is started by a trigger 52 depression of which withdraws a catch 19 from a tooth 18 on the drum 11. The drum carries a cam 46 which depresses a lever 45 bearing on a spring pressed plate 48, depression of which causes a finger 42 to release the shutter. During this movement the wheel 16 is rotated while the wheel 17 remains stationary owing to a gap in the wheel teeth, until the pin 55 reaches the end of the slot 57, when both will rotate together and actuate the winding mechanism. A gap in the teeth of the wheel 16 allows the wheels to return to the original relative position. The winding mechanism is connected to a counting-mechanism 37 through a Maltesecross mechanism. The rate of operation is controlled by a regulable governor 27. The apparatus is attached to a camera by a lock 15. The winding mechanism is enclosed in a casing 9 which may be attached to the camera 3 by a latch 60 actuated by a handle 15. In actuating the handle 15 a bar 39 carrying a rack 40 engaging a toothed wheel 41 is longitudinally displaced by an eccentric 38. The wheel 41 is mounted on a shaft connected to the finger 42. Before the winding mechanism is connected to the camera the finger 42 lies in a position out of the plane of Fig. 1, but when the handle 15 is actuated to lock the mechanism the finger 42 is turned under the spring 43.

Abstract: 1506821 Radio beacon TULL AVIATION CORP 3 Feb 1976 [14 Feb 1975] 04145/76 Heading H4D A radio glide slope I.L.S. compatible beacon, of the kind comprising a vertical array of aerials 10, 12, 14, 15, 16 aligned to produce corresponding beams 18, 20, 22, 23, 24, overlapping in elevation; the aerials being energized sequentially with energy having relative amounts of 90 Hg and 150 Hg modulation varying from aerial to aerial, such that along a glide slope 26 to be defined, (e.g. at 3 degrees) the relative amounts are equal, suffers from ground reflection errors if the beams are all of the same width. The two lowest beams (possibly just the lowest) are therefore reduced in width, e.g. from 1À87 degrees (beams 18, 20, 22) to 0À93 degrees whereby with the two beams having respective elevations of 1À87 degrees and 1À27 degrees an obstacle subtending an angle of 0À53 degrees at the beacon site can be accommodated. By removing the lowest beam 24 (Fig. 3, not shown) the maximum obstacle angle is increased to 1À1 degrees, whilst by tilting the array up such that the angle of beam 24 becomes 2À0 degrees (with corresponding change of the modulation to keep the 3 degree glide slope) the angle is increased to 1À26 degrees (Fig. 4, not shown). The modulation is pulse width, using techniques described in Specification 1,334,201.
