Title: Frequency-modulated approach beacon (localizer)
IPC: G01S1/40
Filed: 1961-04-21
Abstract: 974,495. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. April 21, 1961 [April 27, 1960], No. 14567/61. Heading H4D. In a localizer beacon producing a Doppler effect frequency modulation by the cyclic energization of the aerials in a linear array transmitter outputs on first and second frequencies are switched successively and cyclically to each aerial and the transmitter output on the first frequency is amplitude-modulated at the switching frequency. In the embodiment the aerial array is as shown by Fig. 1. Some 10% of a first transmitter output on 110 mc/s. is coupled successively to each aerial by a first reciprocating switch; a second transmitter output, some nine times larger than that of the first output, on 110 mc/s.-9960 c/s. is coupled successively to each aerial by a second reciprocating switch whose movement is synchronized with that of the first switch but which moves in the opposite direction, and the second output is amplitude-modulated by a 30 c/s. signal in synchronism with the movement of the switches. Hence at low azimuthal deviations (<10.5) from the approach course. the relationship between angular deviation 8 and ensuing frequency modulation is approximately sinusoidal. The amplitude of frequency deviation with respect to 8 for 8 = 0 to 90 is illustrated, Fig. 2 (not shown). The lowfrequency output of the aircraft receiver discriminator is discussed, Figs. 3a, 3b, 3c (none shown); such receiver may be a known V.O.R. receiver. The amplitude-modulation at 30 c/s. is the reference signal. In a conventional V.O.R. receiver a flag indication alarm is given if one of the three signal components does not appear at the receiver output; with the present beacon such an alarm would ensue when the aircraft flies along the approach course. To prevent this, one transmitter output is frequency-modulated at 30 c/s. with a small deviation.

Title: Improvements in or relating to the production of calcium cyanamide
Inventor: CHARD STANLEY
IPC: C01C3/18
Filed: 1950-06-12
Abstract: Calcium cyanamide is prepared by reacting ammonia and carbon monoxide, preferably at about 750 DEG  C., with activated lime which is obtained by calcining completely small size limestone, preferably 1/16 inch to 1/2 inch diameter, so that the temperature does not exceed 1000 DEG  C.  A preferred activated lime is obtained by calcining the small size limestone at 800 DEG  C., hydrating the lime and then dehydrating at 400 DEG  C.  Nitrogen may be present in the gaseous mixture.  After the reaction the gases, containing some hydrocyanic acid, may be scrubbed with water to give a solution which is distilled at 60 DEG  C. in a current of inert gas such as carbon monoxide, alone or mixed with nitrogen.  The carbon monoxide and ammonia from the distillation may be recycled to the cyanamide process.  The distilled liquid may be decarbonated, and part re-distilled to give more ammonia while the remainder is used in the scrubbing step.  Tail gases from the scrubbers may be scrubbed with copper ferrate and the residual nitrogen and hydrogen is either used as fuel or to make ammonia for the cyanamide process.

Title: Method of converting steam driven cable ploughing engines or tractors to internal combustion engine drive
IPC: A01B3/68
Filed: 1935-05-23
Abstract: 450,997. Tractors. McLAREN, Ltd., J. & H., Midland Engine Works, and ROSKILLY, W. W., 50, Moor Grange View, Spen Lane, both in Leeds. May 23, 1935, No. 15067. [Classes 79 (i), 79 (ii), and 79 (v)] A steam-driven cable ploughing engine or tractor is converted to internal-combustionengine drive by removing the steam engine, mounting an internal - combustion engine longitudinally of the tractor on a frame secured to the boiler barrel, and transmitting the drive from the engine through bevel gearing to a straight transverse shaft which takes the place of the steam engine crank-shaft. In the construction shown, a Diesel engine 1 is mounted on a frame comprising side plates 3 fixed to the boiler barrel 4 and smoke-box 5. A shaft 18 carrying change-speed pinions 65, 66 replaces the steam engine crank-shaft and is driven from the engine 1 through the clutch 13, a flexible coupling 48, bevel reversing gearing 46, 49, Fig. 5, and spur gears 72, 71, the ratio of which can be readily changed by substituting other pairs of gear-wheels. The reversing gear and its driving and driven shafts 43, 38 are carried by a gear-box 27 mounted on the top of the boiler barrel 4. A hand lever 61 working over a quadrant 64 controls the reversing gear. The Diesel engine may be reversible and the reversing gear dispensed with. The shaft 18, driven through the reversing gear and the changeable gears 72, 71 drives a vertical-shaft winding drum (not shown), through bevel gears 68, 69. In order that the winding drum may be held stationary when the engine clutch 13 is disengaged a brake block 87, Fig. 3, acting on a drum 86 on the clutch shaft, is controlled by the clutchoperating linkage. A hand lever 82 controls the clutch through a link 83 and an arm 80 on a shaft 77, this shaft having an arm 91 connected by a link 93 and bell-crank 92 to a screw 95 passing through the free end of the brake block. Nuts 89, 96 on the screw are screwed tight against a sleeve 97 on the screw, and the brake block is held in position by a spring 90 bearing against the block and the nut 96. When the shaft 77 is rotated the clutch is disengaged and the brake block forced against its drum by the spring 90. Further rotation of the shaft 77 to complete disengagement of the clutch compresses the spring 90, the sleeve 97 and screw 95 sliding through the brake block. The stage at which the brake comes into action can be adjusted by screwing the nuts along the screw 95.

Compressed air from compresor 10 passes through duct 13, heat exchanger 14, combustion equipment 15 to turbine 12 which drives compressor 10. The exhaust gases from turbine 12 are directed by pivoted flap valves 31, 33 to one or more power turbines 26, 27, 28 and thence through duct 60 to heat exchanger 14. Each power turbine drives a gearing input shaft 36, 37, 38 which are respectively rotatably mounted in gears 44, 45, 46, the drive being transmitted through clutches 41, 42, 43 each having a helically splined member 54 provided with dog teeth 55 for engagement with dog teeth 56. When an input shaft speed is at least as great at its respective gear speed the member 54 moves to engage the dog teeth. The drive is transmitted through shaft 50 and gears 51, 52 to an output shaft 53 which may be fitted with a hydrodynamic brake 61. The drive is then transmitted through forward or reverse gears 63, 65, 67 or 62, 64 which are selectively engaged by axial movement of a drive shaft 66, carrying a dog clutch 68, to drive a pair of gears 72 each of which engages a gear 73 on a locomotive axle. Operation. At starting, flap valves 31, 33 are in their full line positions and only turbine 26 is driven to effect a low-gear drive to the output shaft 53. When turbine 26 attains its maximum speed flap valve 33 is gradually moved to the broken line position causing turbine 28 to be brought up to its synchronizing speed at which speed the clutch 45 is moved to effect an intermediate gear drive to the output shaft 53. Flap valve 31 is then moved to its broken line position and flap valve is moved to its full line position thereby bringing turbine 27 up to its synchronizing speed at which speed clutch member 45 is moved to effect a high gear drive to the output shaft 53.
