Abstract: 456,838. Directive wireless signalling. ATKINS, H. C., 207, Princes Gardens, West Acton, London. Feb. 11, 1935, Nos. 4321 and 24357. [Class 40 (v)] A landing-path for an aeroplane is formed by the intersection of two rotating beams from beacons A, B, Fig. 1, the elevation of the beams being simultaneously varied to give the curved track marked CD in Fig. 1A. Each beam is separately modulated at a constantlyvarying frequency, so as to give the aviator an indication both of his position and height. The modulation may be effected by means of gaseous discharge tubes placed in the path of the beam. The rotating beams may be replaced by stationary diverging beams, A, B, Fig. 3A, an additional beam RB being swung vertically up and down to indicate the landing track.

Abstract: 1291171 Magnetic tape transport systems MOHAWK DATA SCIENCES CORP 29 Jan 1970 [25 March 1969] 4383/70 Heading G5R In a take-up arrangement in which tape 1 passes to a reel 13 on a shaft 82 of a motor (54) via an idler roll 14 mounted on arm 96, urged by spring 97 to take-up slack, when the slack exceeds a certain amount, an auxiliary drive assists the motor to reduce it. As the arm 96 moves to the right, Fig. 3, arm 106 moves in a clockwise manner to allow arm 80, 81 to move about shaft 70 so that roll 94 is brought into contact with roll 86 on shaft 82. Capstan drive motor (52) has a shaft 62 which operates through belt drives 68, 90 to rotate rolls 92, 94 so that as roll 94 is brought into contact with 86, the latter is accelerated, flywheel 76 minimizing reaction on the capstan drive. If the slack is unduly decreased, arms 96, 104 cause brake band 85 to slow take-up drive-shaft 82. An idler roller 42 and arm 126 similarly apply a brake band 120 to the supply drive-shaft 138. A belt 60 applies drive to the forward and reverse capstans 20, 36, pressure rollers 22, 34 being operated by solenoids 156, 154 while vacuum applied over tube 164 holds the tape against suction pads 24, 32.
