The conveyer forming the floor of the reservoir is laterally flexible, and in at least a part it extends along a helix. The articles enter the reservoir at one end and are discharged, when needed, from the same end. The conveyer carries a wall member 418 (Figs. 18 and 19) which defines the end of the stack of articles in the reservoir and moves with the conveyer. The member 418 is connected with the conveyer 602 by a cord 424 carrying spacer blocks 420 and sponge rubber spacer rings 426. The conveyer 602 comprises an article-support member 310 (Figs. 15 and 16) of acetal or nylon having a zigzag formation which permits lateral flexing. Pins 322 provide lateral location of the cigarettes, and guide portions 340 co-operate with a nylon track member 336. Traction is provided by a chain 324 secured to the member 310 by studs 326. Recesses 344 in the member 310 receive fingers (not shown) for guiding cigarettes on to, and away from, the conveyer. In a modified form (Fig. 10) the conveyer is provided by a spiral surface 232 on a drum 230. The latter is driven by the action of a motor 252 connected to a drive roller 258 which co-operates with a spiral surface 244 on the inside of the drum wall. The surface 244 ensures the necessary vertical traverse of the drum. A bridge 238 provides a connection between the drum and an input conveyer 236. Various feeler operated mechanisms are described for detecting the rate of feed of cigarettes into and away from the system.

Abstract: 1477925 Detecting displacement; pressure; presence electrically SIEMENS AG 10 June 1974 [12 June 1973] 25601/74 Heading G1N [Also in Division H1] In a transducer of the kind including a pair of spaced magneto-resistive plates on a pole of a magnet, and an iron member movable to vary the field passing through the plates the iron member is dimensioned and/or disposed so that the change in resistance of the plates is linearly proportional to the change in position of the iron member over as large a range as possible. In the arrangement of, Fig. 2, the magneto-resistive plates, connected in adjacent arms of a bridge circuit, Fig. 4 (not shown) are arranged on a pole shoe on permanent magnet 2, the pole shoe being provided with a central recess 3. The iron member 6 whose movement is to be converted into an electrical signal is inclined at an angle α towards the longitudinal direction of the plates 4, 4' and the projection 'd' of the width 'b' of the member 6 on to the longitudinal plane of the plates is made at least equal to the diagonal of one of the plates 4, 4'. Thus in one end position member 6 completely covers one plate 4 and in the other end position, covers the other plate 4' the member 6 beginning to cover one plate and uncover the other as it moves from one end position to the other. The output obtained from the bridge circuit is linearly proportional to the displacement of the member 6 between the two end positions. Potentiometer, Fig. 7 The above transducer may be used as a linear potentiometer by mounting a body 71 having an iron layer 72 on a rotatable shaft 70, the body 71  being mounted at the angle α. Thus as the shaft is  rotated the layer 72 moves across the resistive plates I mounted on the permanent magnet 2 and a variable output is obtained from the bridge circuit.  The angle α may be 90 degrees and the width of the iron member 6 made equal to the width of a field plate plus the distance between the field plates, Fig. 3 (not shown), so that as the member moves it begins to uncover one plate and cover the other. Such an arrangement may be used in a: - Pressure sensing device, Fig. 5 in which a membrane 50 is secured to iron member 6 which moves over the resistors 1 or an Axial-Play-sensing device Fig. 6 in which axial displacement of rotatable shaft 60 is detected by movement of member 6 relative to one or two magneto-resistive arrangements 61, 62.
