Abstract: 1,251,051. Cigarette-making machines; testing cigarettes. HAUNI-WERKE KORBER & CO. K.G. 26 Sept., 1968 [9 Oct., 1967], No. 45711/68. Heading A2C. In an apparatus for measuring the filling factor of tobacco, a jet-like stream of gaseous medium is directed upon the wrapper of a wrapped tobacco rod to effect thereby a local elastic deformation of the rod against the pressure of the tobacco within the wrapper, and the magnitude of such elastic deformation of the rod is assessed. The filling factor is defined as the overall property or quality of a required feel or appearance of a wrapped tobacco article, and which is the result of a number of different factors. The invention utilises a ring measuring nozzle and with one form of ring measuring nozzle 102, Fig. 1, a cigarette rod 101 passes through a ring-shaped outlet opening 109 of a ring chamber 107, which chamber 107 also communicates with a duct 108 leading to a measurement connection 106. Compressed air is supplied through a connection 103. With another form of ring measuring nozzle 2, Fig. 2, a ring-shaped opening 11, adjacent the ring-shaped outlet opening of a ring chamber 7, leads through a duct 8 and a further ring chamber 12 to a measurement connection 6. As shown in Fig. 6, a continuous cigarette rod 301 passes through a ring measuring nozzle 306 supplied with compressed air through an adjustable restriction 327 and a laminar resistance 328. A pressure output signal from the nozzle 302 is fed via a connection 306 and a pipe 324 to a pneumatic control arrangement 322 to which is also fed compressed air by a pipe 323. The control 322 supplies compressed air along pipe 319 or pipe 321 as required in response to measured departures of the rod 301 from the required standard to actuate a reversible air motor 317 to raise or lower the cutter 316 of a trimmer mechanism 311 sited above a tobacco filler stream in a circumferential duct 309 of a suction forming wheel 308. In another embodiment, also shown in Fig. 6, the pressure output signal from the nozzle 302 is fed by a pipe 702 to a control arrangement 701 that adjusts the speed of the driving motor 305 of the distributor 303 that showers cut tobacco 304 onto the belt 307 that feeds the forming wheel 308. In a modification, Fig. 8 (not shown), the trimmer cutter is provided with a pneumatic piston drive in lieu of the air motor 317. A further embodiment, Fig. 5 (not shown), comprises a pneumatic computing arrangement following a ring measuring nozzle for automatically determining the deviation of the filling factor measurement values of cigarettes from an arithmetic mean value. Pneumatic computing devices for automatically determining the standard deviation of the filling factor measurement value of a cigarette rod, and for automatically determining the standard deviations from pneumatic signals which correspond to the difference between the measurement value and an average value, are also disclosed and illustrated.

Abstract: 1,267,267. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Jan., 1970 130 Jan., 1969; 8 Aug., 1969; 18 Dec., 1969], No. 3874/70. Heading H4F. In a PAL colour television chrominance signal component demodulator, -to reduce the influence of differential phase error between the subcarrier generated from the separated 'burst signals and the colour information in the chrominance signal, the generated subcarrier is phase corrected in response to a signal derived from the output of the demodulator circuit which contains components which are a measure of the magnitude and direction of the differential phase error. As shown, Fig. 1, the outputs of the chrominance signal synchronous demodulators 37 and 43 are fed via time selection circuits 57 and 59 (see later) and low-pass filters 63, 65 and 67, 69 to a non-linear signal handling circuit 75 (see later), the output of which is fed via a low-pass filter 79, 81 to a phase correction circuit 29 which corrects the phase of the subcarrier from the chrominance subcarrier generator 13, the frequency and phase of which is fixed relative to the mean frequency and phase of the swinging burst signal by means of a control loop including synchronous detector 9 and a D.C./A.C. component separator circuit 17. The outputs of the demodulators 37 and 43 each have a component of constant sign and a component of alternating sign, i.e. (B-Y) cos #Œ(R-Y) sin # and Œ(R-Y) cos # - (B-Y) sin # The sin # component in each signal is proportional to the differential phase error. The components of constant sign are fed to the non- linear handling circuit 75 which either forms the product or the quotient thereof which is used after filtering as the control signal. Time selection circuits 57 and 59 may be provided to ensure that the mean value of the signal is determined only over a portion, e.g. 5-20%, of each line period. These circuits being rendered conducting only during a portion of each line period by means of a pulse derived from a line flyback pulse and delayed by a delay circuit 83 which may -be controlled by a sine or sawtooth generator having a low frequency. A control signal dependent on (R-Y) and not (B-Y) may be derived-by passing both the demodulator outputs first through 180 degrees phase shifters operated by half-line-frequency switching voltages before they -are applied to the non-linear handling circuit. Both control signals may be used simultaneously in which case even when one of (R-Y) or (B-Y) is zero a control signal is formed.  A non-linear handling circuit is described with reference to Figs. 2 and 3 (not shown), in which the effect of the polarity of the colour difference signals is nullified, the control signal always comprising - (B-Y sin #. A quotient forming non-linear handling circuit is described with reference to Fig. 4 (not shown) which comprises two logarithmic transfer circuits, the outputs of which are subtracted and passed to an anti-logarithmic transfer circuit and a sign correction circuit.

The workpiece 34 is mounted centrally on a rotatable mandrel by resiliently holding the workpiece between opposed spring and a pair of rotating rolls 14 are advanced to contact the workpiece to work harden the surface and form an initial impression. At this stage rolls 50 contact the workpiece so as to reduce the ovality of the workpiece caused by the rolls 14. After the rolls 14 have been held in their most advanced position for up to two revolutions, the rolls 14 and 50 are retracted and the workpiece removed from the mandrel. In another embodiment the rolls 14 are skewed to reduce the ovality of the workpiece during rolling. An outer bearing ring is made by inserting a cylindrical workpiece 82 in a roll 86 and resiliently holding the workpiece between collars 92 and 94. A rotating roll 84 is then moved in the direction of arrow 106 to start the forming of the workpiece. (For Figures see next page.)
