Abstract: 1,038,551. Cigarette-making machines. MOLINS ORGANISATION Ltd. Feb. 21, 1963 [Feb. 22, 1962], No. 6988/62. Heading A2C. In the production of a continuous rod tobacco filler, usable tobacco and unusable stem portions are separated in three stages, the first two stages being effected by air streams and the last stage by mechanical sieving. The tobacco is picked from a carded drum 1 by a picker roller 3 and directed by a winnower 7 over a plate 8 having holes 9 therein which direct most of the usable tobacco around a perforated roller 11 to which suction is applied and up a passage 10 for formation into a filler on the underside of a perforated conveyer. The remainder of the tobacco falls down a trap 12 and is fed between a roller 15 andd resilient roller 16 into a passage 17 up which rises a second air stream which carries away further light usable tobacco to the passage 10 via a passage 18. The rest of the tobacco falls upon a plate 29 where it is picked up by rotating paddles 30. The paddles 30 sweep the tobacco over sieve bars covering an opening 36 into which further usable tobacco falls. The unusable tobacco remaining on the paddles is discharged into an opening 38 and pipe 40 for further processing. The tobacco falling through the opening 36 is again picked up by the paddles 30 at the bottom of the opening and carried over a further sieve 39. Particles passing through the sieve 39 are carried up a passage 42 towards the passage 10 while particles not passing through the sieve 39 are retained by the padles 30 for further presentation to the sieve opening 36.

Title: Device for the remote transmission of rotary movements with correct angular displacement
IPC: H02K24/00
Filed: 1948-03-15
Abstract: 654,184. Selsyn machines. AKTIEBOLAGET BOFORS, and PALME, K. B. March 15, 1948, No. 7749. [Class 35] [Also in Group XXXVIII] A single-phase Selsyn comprises a stator which produces a uniform field between its poles and a rotor having a winding without a magnetic core. The laminated stator 1 encloses a pair of non-magnetic coil holders 2 having slots for locating the coils 3. The rotor coil holder 4 is also of non-magnetic material and carries an accurately formed coil 6, the voltage induced in which depends on its angular position. Fig. 5 shows how a pair of Selsyns 9, 10 of this construction are energized by a common reference potental from a source 13 and the difference in angular position of the two rotor coils 14, 15 appears as a voltage difference which is passed through an amplifier 21 which is also supplied with the reference potential and used to control a motor 19 which corrects the position of the following Selsyn 10 and adjusts the position of the load 20 in accordance with the controller 18. Fig. 9 shows a Selsyn in which the stator 23 is axially extended to allow a pair of coils 32, 33 to be mounted along the rotor shaft. These coils are mutually at right angles so that when one is in its insensitive position the other can operate. Alternatively two Selsyns coupled together may be used. Fig. 10 shows a followup system employing a pair of Selsyns 34, 35 with quadrature coils 38, 39 and 40, 41. The coils are connected through slip-rings and, in the case of the transmitter, through commutator segments 53, 54 and 64, 67 which connect the coils alternatively only during their active periods, i.e. whilst the displacement is 45 degrees on either side of the zero voltage position. The outputs of the Selsyns are fed into an amplifier 73 controlling a motor 80 driving the load 82 in accordance with the follow-up required. In order to prevent relative displacement by whole numbers of revolutions, the Selsyns may be subject to the overriding coarse control of a low-geared Selsyn system.
