Abstract: 1,171,765. Feeding cigarettes to packaging machines. MOLINS MACHINE CO. Ltd. 31 Oct., 1966 [1 Nov., 1965], No. 32732/69. Divided out of 1,171,765. Headings B8C and B8S. Cigarettes are continuously removed from a supply 39, Fig. 3, above a packaging machine as described in the parent Specification, and accelerated down a channel 41 by belts and rolls 46, 51, 52, 55, 58, 67, 73 and 74. The channel narrows in steps defined by rotating rolls 51 and 55 which project in the channel and thus accelerate and reduce the number of transverse rows simultaneously. The cigarettes are fed from the channel into a rotating annular hopper 8 their velocity being approximately the same as the hoppers, and are constrained from movement by an endless " snake chain " 751, Figs. 7 and 8, lying on the cigarettes around the hopper and raised at the hopper filling position by spring-loaded arms 752. Outlets around the hopper, lead to shoots 7, with outer walls 85, Figs. 8, 8A, 9, and consisting each of three channels formed by partitions 88, 89 and terminating in a base-plate 11 having a projection 12, to displace the cigarette rows by half a cigarette width in the centre channel, Fig. 9. Rotary feeders 124 are arranged at the shoot inlet. The shoot moves progressively during rotation from a high position, Fig. 8, to a low position, Fig. 8A, the difference in the vertical displacements being compensated for by flexible plates 91 joining each shoot to its neighbours. An end testing feeler device 138 moves radially outwards to contact the lowermost twenty cigarettes in the shoot, any defect being transmitted to a memory device for later package rejection. At the lowest position of the shoot a plunger 10 on a slide 129 pushes the bottom twenty cigarettes outwardly from the shoot into a compression box 13 where opposite ends abut a further end-testing device.

Class 35 An electrostatic generator for the ignition of I.C. engines has contact brushes engaging the plate on which charges are induced for conducting the generated charge to the load, these brushes being centrifugally raised from actual contact with the plates at such a speed that the generated voltage is sufficient to pass over a small spark-gap instead, thus dispensing with frictional wear. The machine has an external rotor 11 carrying a pair of mutually insulated charged plates 1, 2, which induce charges in a series of fixed plates 4. Brushes 9 earth the diametrically opposite pairs of stator plates in succession and brushes' 13 subsequently carry their induced charge to the inducing plates 1, 2 respectively. A distributer contact 17 connected to plate 1 feeds timed charges to electrode 18. The brushes 9, 13 are of spring material and at a certain speed are flung out of contact with the plates 4 into the position shown dotted, the charge then passing to point discharge brushes 14. In a modification (not shown), the spring brushes are restrained from more than a certain separation from the stator plates so that they can carry the spark discharge. It is stated that the brushes may be raised by suction or mechanical linkage.

[Class 98 (i)] [See also Group XXXVIII] In making a photographic sound record of the variable density kind, a test record is made simultaneously with the sound-recording process. By means of the test record, which is of uniform density, the proper conditions under which the sound record should be developed or printed, or both, can be ascertained, the method being particularly intended for use in recording processes in which in addition to audiofrequency variation of the light intensity, variations of the mean light intensity are produced. The Figure shows diagrammatically an apparatus for carrying out the invention. A sound record 5 is made on a film 4 by modulating a beam from a lamp 1 by passing it through a device 2 which varies the mean intensity and through a device 3 which produces audio-frequency variations. At the same time, a test record 6 is made on the same or on a similar film, by means of an unmodulated beam from the source 1 or from an optically identical source. The test record may be made continuously or intermittently along the whole length of the film. After recording, a section of the test record is first developed and, if desired, printed, and the most favourable conditions for processing the sound-record may thus be ascertained.
