Abstract

1509206 Tossing cigarettes HAUNI-WERKE KORBER & CO KG 10 June 1975 [14 June 1974 22 Nov 1974] 24843/75 Heading A2C [Also in Division G1] Apparatus for checking the tobacco density of cigarettes Z includes two capacitor electrodes 457, 458 against which the ends Ze of the cigarettes brush, which electrodes are energised from an a.c. source 459b and form part of a resonant circuit 462 of which the output signal amplitude is evaluated in a circuit 461b. The evaluator output is connected to input a of an analog store 512 which stores a comparison signal generated when a space between cigarettes is located in front of the electrodes under the control of timing pulses from a generator 513 synchronised with the drive of the end scanning drum 429 carrying the cigarettes. A device 518 forms the difference between a measurement signal from the evaluator and a stored comparison signal and transmits it to a threshold detector 476 via an AND gate 519 receiving also a clock pulse from a generator 521 indicative of the presence of a cigarette in front of the electrodes. If the difference is greater than the threshold value a fault signal is transmitted via register 477 to actuate removal of a defective cigarette by air blown through a pipe 452. Fig. 4 (not shown) includes an arrangement whereby the two pulse generators are substituted by a circuit sensing minima and maxima of the evaluated signal.
