Abstract: 1,110,790. Stripping tobacco. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 20 Dec., 1965 [21, Dec., 1964], No. 51844/64. Heading A2C, [Also in Division B2] Tobacco leaves are stripped by concentrically arranged stripper drums and cages of different diameter mounted one within the other. As shown, tobacco to be stripped is fed by a shoot 62 to a stripper 4 consisting of a stripper drum 6 and stripper cage 8. Stripped material passes up ducts 42 to one of three separating chambers as 38 by reason of suction applied by a common exhaust duct 60. Heavier material consisting of stems and stems with leaf still attached fall back through openings as 51, 53 to a stripper 21 consisting of a drum 32 and cage 34 when further separating takes place, the separated material flowing up ducts as 56. Heavier material falls through the strippers on to a conveyer belt 64. The stripper 4 is driven by wheels 16 which engage a ring 14 on the drum 6 and the stripper 21 is driven via a pulley 30 and shaft 22. In an alternative embodiment the cage of the inner stripper has mounted thereon stripper teeth, is rotated and constitutes drum of the outer stripper. In this case the ducts 56 are omitted, the material stripped in the inner stripper being returned to the separating chamber via the outer stripper. New material may be introduced into the inner stripper initially instead of the outer stripper, three concentric strippers may be used instead of two, the material may be introduced and heavy material removed by means other than shoots and conveyer belts respectively and the volume of the separating chamber may be made variable.

Abstract: 1,224,559. Measuring flow rate, electrically. BADGER METER MFG. CO. Nov. 7, 1968 [Feb. 5, 1968], No. 52752/68. Heading G1N. [Also in Divisions G4] In a nuclear magnetic resonance flowmeter comprising a "tagging" station 14 and a detecting station 16, the detected signal is used to control the frequency of a voltage-controlled "tagging" oscillator 44 in such a way as to keep the detected and "tagging" signals in a predetermined phase relationship whereby the frequency of the oscillator 44 is indicative of the flow-rate of fluid in the conduit 10. As shown in Fig. 1, two D.C. solenoids 12, 18 align nuclei in the fluid with the flow axis. Coil 20 is fed with r.f. current at the Larmor frequency of said nuclei and amplitude modulated (sine- or square-wave) at the frequency generated by the oscillator 44. At the detecting station, coil 26 is energized at the Larmor frequency (now different from what it was at the tagging station) and coils 22, 24 pick up changes in the magnetization in the fluid which are demodulated at 48 and compared in phase at 50 with the output of oscillator 44 which is controlled to maintain phase quadrature between the signals. A counter 56 registers total flow and a frequency meter may be connected to 58 to indicate flow-rate. Modifications. R.f. generator 38 may generate a band of frequencies around the Larmor frequency. The nuclei may be aligned perpendicular to the flow axis. R.f. generator 38 and coil 20 may be omitted, coil 18 being pulses with D.C. at the frequency generated by oscillator 44, Fig. 5 (not shown). A pre-polarizing coil (64) Fig. 6 (not shown) may be arranged upstream of the coil 18 whereby pulsing coil 18 produces adiabatic reversal of magnetization in the fluid, effectively doubling the amplitude of the detected signal.
