Abstract: 1,250,777. Automatic phase control, transistor oscillators and ramp generators. WESTERN ELECTRIC CO. Inc. 11 Dec., 1968 [13 Dec., 1967], No. 58795/68. Headings H3A and H3T. A phase locked oscillator system comprises a voltage controlled oscillator 310 and a phase comparator which includes a ramp generator 320. Means are provided for increasing the duration of the ramp function if the error signal from the comparator is indicative of a phase error exceeding a predetermined value. An output pulse from oscillator 310 switches on transistor 341 to charge capacitor 344 and at the end of the pulse, capacitor 344 commences to discharge, at a rate determined by transistor 345. Whenever a reference pulse is received on line 331, gate 330 opens, and the potential on capacitor 344 at that instant is transferred to capacitor 332 to provide an error signal indicative of the time interval between the oscillator output pulse and the reference output pulse. This error signal is fedback over line 312 to control the oscillator frequency. If the frequency drifts outside the lock-in range, the error signal falls to zero, and transistor 362 conducts to change the conductivity of transistor 345, thus increasing the duration of the ramp function produced by the discharge of capacitor 344. An error signal is thus once again produced to cut off transistor 362, after which the charge on capacitor 391 slowly leaks away allowing the conductivity of transistor 345 to revert to its normal value and reduce the duration of the ramp function again. Oscillator 310.-Capacitor 340 charges through. constant current source 321 at a rate determined by the control voltage on line 312, and the setting of potentiometer 311 until transistor 313 conducts. The output from 313 switches on a monostable blocking oscillator 317 which produces an output pulse which in turn triggers a similar blocking oscillator 336. The output pulse from 336 turns on transistor 329 to discharge capacitor 340, and the cycle then repeats.

Abstract: 1314732 Puffing tobacco ROTHMANS INTERNATIONAL Ltd 19 April 1971 [19 Feb 1970] 8144/70 Heading A2C [Also in Divisions F4 and H5] Apparatus for treating tobacco, to cause its cellular structure to expand and/or to cause the fibres to move apart from one another, comprises a conveyor G which carries the tobacco through a high frequency electric field, and a sheet of insulating material T, fixed at T 1 , which lies on top of the tobacco as it passes between the electrodes of the oven C. The tobacco on belt G is compressed by a roller X before being passed to the oven C, and is moved by the belt under the overlying sheet T, which is of glass fibre coated with silicone rubber. This prevents the escape of moisture until the tobacco is clear of the electrodes and thereby maintains a uniform loss factor, which, in turn, reduces localised burning of the tobacco. The belt G transfers the heated tobacco to a further belt S and then passes over a rotating, cleaning brush V. The cooling unit, Fig. 6 (not shown) comprises a fan which draws air upwards through the belt S and the tobacco thereon. An arrangement of photo-cells and lights M, on the feeder tube K, maintains a uniform flow of tobacco by controlling the feeder A.

Preferably, the material is moved through the heating zone at a speed greater than 6 m. per min., especially between 6À5 and 10 m. per min., in the presence of a purifying and/or protective gas stream, flowing countercurrent to the direction of movement of the material, which is heated to 500 to 3000‹ C., especially to 1100‹ C. at a rate of 30,000‹ to 85,000‹ C. per min. In apparatus as shown, carbonaceous fibrous material 1 in the form of a fabric, ribbon, strand, filament or yarn is wound off roll 2 and enters central channel 3 of a cylindrical electric furnace 4. The channel, which may be graphitelined, extends normally to the axis of the furnace. The material is heated to the required temperature while passing through the heating chamber 6 of channel 3, and volatile matter formed thereby is forcibly evacuated in the opposite direction by the action of hydraulic seal 7 and suction pipe 8, optionally with the assistance of a stream of purifying or protective gas supplied through nipples 9. The seal 7 moves also to cool the material, which then passes to drying chamber 13 prior to wind-up on driven take-up roll 15. The furnace comprises a cylindrical metal housing 20 having a water-cooled jacket 21, and containing coaxial inner and outer screens 23 and 22, made of graphite or other refractory material separated by heat insulation material 25, e.g. carbon black. A tubular heater 26 is disposed axially in the heating chamber 6, and above the heater and below the uppermost screen is the central channel 3. Current is supplied to each end of heater 26 by water-cooled cap ring 27, contact between each ring and the end of the heater being realized through an intermediary wedge 28. This contact is sealed by end cap 29, and one end cap has an inspection hole 30 which permits measurement of the temperature of heater 26, e.g. by means of an optical pyrometer. Arrows B and C indicate the direction of supply of cooling water to caps 27 and 29 and housing 20.
