Title: Process and apparatus for the production of artificial cigarette tobacco
IPC: A24B3/14
Filed: 1967-09-04
Abstract: 1,138,280. Reconstituted tobacco threads. SCHIFF & STERN G.m.b.H. 4 Sept., 1967 [10 Oct., 1966], No. 40393/67. Heading A2C. In an apparatus for producing comparatively short artificial tobacco threads, during each half revolution of a rotating feeder 3 a portion of tobacco pulp is squeezed, by a slide 8 that intermittently reciprocates within a diametrical slot 9 in the feeder 3, out of a space 26 and into a pressure chamber 4 from which it passes out through holes 6 in a plate 5 to form threads. The pulp is progressively squeezed out of the space 26 during the rotation of the feeder 3, further pulp from a hopper 1 simultaneously filling a similar space as it forms in the opposite side of the slot 9 during the downward squeezing movement of the slide 8 until the position 8<SP>1</SP> is attained. The slide then remains stationary within the slot 9 until the rotation of the feeder 3 through the balance of the half revolution is completed, when the process is repeated. During the non-squeezing part of the rotation of the feeder 3 the threads are cut off by a grate of knives or by a tangentially applied air blast that preferably contains tobacco dust. The cut threads are dried whilst falling through a casing 38, by a continuous counter-current of hot air supplied by radiators 44, and then deposited on a conveyer 42.

In a conveyer system in which load carriers are propelled along a track by dogs depending from a chain running along a vertically spaced track, a plurality of actuating elements, responsive to the presence of a carrier on the track, are each operatively associated with a carrier drive disengaging element situated in the position next in rear of the actuating element to disengage the drive from the next arriving carrier whereby advancing carriers are in turn brought to rest at spaced positions along the track in rear of the foremost stationary carrier. In the arrangement shown, load carriers 13 are propelled along a track 12 by pairs of vertically movable dogs 15, 16 depending from a chain 11 running along a track 10 and engaging a driving member 17. The carriers 13 are stopped at predetermined stations by an actuating element 38 supported from rocker arms 40, 41 connected to pivotally mounted spindles 37 vertically supported at the side of the tracks 10, 12 and carrying carrier drive disengaging elements 23 and stops 20. An actuating element 38 on being engaged by a leading carrier 13 is moved outwardly and forwardly to rotate a spindle 37 in the rear thereof to move a carrier drive disengaging element 23 and a stop 20 into the path of a succeeding carrier 13. The element 23 is engaged by a cam follower 32 to lift a dog 15 out of driving engagement with the driving member 17 of a succeeding carrier 13 and the stop 20 prevents further forward movement of such carrier 13, Fig. 2. The actuating element 38 and associated parts are returned to their inoperative position by a spring 42 once the leading carrier 13 moves out of engagement with such element 38.

Abstract: 1382176 Frequency band separation WESTERN ELECTRIC CO Inc 6 Sept 1972 [9 Sept 1971] 41249/72 Heading H1W [Also in Division H4] Arbitrarily polarized signals of different frequencies (i.e. occupying different, spaced frequency bands) are coupled from a common path to different branches, whilst preserving the polarization of the signals. Thus, signals E 1 , f 1 , #<SP>1</SP> 1  and E 2 ,f 2 , #<SP>1</SP> 2  are directed from a common path 26 respectively to paths 28, 27, the angles #<SP>1</SP> 1 , #<SP>1</SP> 2  being preserved. The waves are fed to a wide-band polarization-selective 3-part network 42 which couples z<SP>1</SP> and x<SP>1</SP> components of both waves respectively to output ports 45, 44. From thence, the x<SP>1</SP> components are fed to a frequency-selective 3-port network 51 which rotates through 90 degrees the component of frequency f 1  and leaves unchanged the polarization of the component of frequency f 2 , whereby the signals are fed respectively to ports 57, 56 and thence to further respective 3-port networks 75, 81. An analogous process is applied to the z<SP>1</SP> components in network 52 which couples the f 1  component to network 75 and the f 2  component to network 81. The original waves E 1 , Eg are reconstituted from their orthogonal components by the networks 75, 81. The invention may be applied to a ground/satellite T/R system in which two orthogonally-polarized signals at a frequency f 1  are received and two orthogonallypolarized signals at a frequency f 2  are transmitted. Because of the Faraday rotation produced by the ionosphere, the transmitted and received signals are rotatated through different angles # 1 , # 2  (see Fig. 1, not shown). The signal paths 27, 28 are coupled respectively to a transmitter and a receiver through respective polarization rotators which connect the Faraday rotation.
