Abstract: 1,101,071. Cigarette making machines. MOLINS ORGANISATION Ltd. 6 Aug., 1964 [9 Aug., 1963], No. 31648/63. Heading A2C. In the production of a continuous tobacco filler comprising metering tobacco from a supply to form a tobacco filler shorts are removed to produce a flow of shorts which is fed back to the filler to produce an oversize filler which is trimmed in such a way that the shorts, after trimming, are retained in the filler. Fig. 1 shows a machine corresponding to that disclosed in the Specification 988,448 in which tobacco is fed by a drum 10 past a refuser roll 13 to a picker roller 11 which projects it across a guide plate 12 into a gap between the member 14, having air passages 15, and a perforated suction roller 16. Tobacco is sucked up a duct 19 against the underside of an air-pervious conveyer band 22 to form a continuous rod. Particles of tobacco not sucked into the duct 19 fall into a chamber 27. Shorts from the tobacco being fed from the space Z fall into the space between a plate 31 and a drum 10 and pass through gap Y into the pockets 39 of a valve 38. The valve 38 is rotated so as to supply shorts continuously to a manifold 40 and pipe 41. The shorts are blown by a fan through the pipe 41 to a horizontal pipe 41A having a nozzle 41B. The spread of shorts from the nozzle 41B is of a length equal to a third of the downstream length of the drum 10. Alternatively, the shorts may be blown through one of the orifices in the plate 14 (Fig. 5, not shown) in which case they are distributed along the downstream 80% of the length of the duct 19. Automatic trimming means as disclosed in Specification 929,338 may be employed, trimming taking place on that portion of the rod not including the shorts.

[Class 105.] An indicator for a semaphore arm and spectacle signal having its lamp continuously supplied with alternating current is of the direct-current polarized type and is supplied with unidirectional current from the lamp circuit through full- or half-wave rectifiers which may be of the metal compound type described in Specification 194,653, [Class 38 (ii), Electric currents, Converting &c.], Failure of the lamp will deenergize the indicator and may so, or otherwise, give a warning. As shown in Fig. 1, a fullwave rectifier 10 is connected across part of a resistance 7 in series with the signal lamp 3 in the secondary circuit of a supply transformer 5. The output terminals of the rectifier are connected to the indication leads 11, 12 through a contact device 15 which is controlled by the semaphore arm 1 so that the polarized indicator 19 is energized normally or reversely in accordance with the signal setting. Failure of the lamp 3 or any fault in the signal setting is shown by the de-energized indicator showing " signal wrong." A separate indicator for the lamp may be connected to the same or to additional indication leads with a separate rectifier. In the arrangement shown in Fig. 5, a direct-current relay 44 in parallel with a rectifier 45 is inserted in the circuit of the lamp 3 so that on failure of this lamp an auxiliary lamp 41 is lit over back contact 46-48. The indicator 19 is energized normally or reversely, in accordance with the position of the signalcontrolled contact 15, over half-wave rectifiers 27 or 28, only if the main lamp 3 is lit and the relay 44 therefore energized to close its front contact 46-47. In the arrangement shown in Fig. 4 two current transformers 33, 34 in the lamp circuit supply two reversely set full-wave rectifiers 35, 36, one or other of which is connected by the signal-controlled contact 15 with the indication leads 11, 12. The indicator instead of being directly actuated, as described, may be controlled by a direct-current polarized relay which is normally or reversely energized by rectified current in the manner described above.. Where half-wave rectifiers are used they may be arranged as byepass rectifiers.
