Patent DE-4115105-A1 (DE)
Inventor: TROEGER GERHARD
IPC: B01D25/172
Filed: 1991-05-08
Abstract: A pilot finger (36) is mounted on a shifting trolley (28) having reversible drive (30), which pilot finger, at the beginning of each forward travel, can be pivoted behind the front filter plate (2) which has not yet been shifted, in order to carry the latter along. A pilot control member (70) can latch onto the pilot finger (36) in order to hold this in an idle position in which the shifting trolley (28) can be moved forwards past the filter plates (2) without carrying the latter along. Likewise mounted on the shifting trolley (28) is a follow-up finger (56) which, at the beginning of a forwards travel, can be pivoted behind the filter plate (2) second from the front which has not yet been shifted, in order to carry the latter along. This pivoting is actuated by a follow-up control member (80), which in a final phase of the pivoting of the pilot finger (36) behind the front filter plate (2) which has not yet been shifted, exerts a torque in the pivoting direction on the follow-up finger (56) arranged behind this. The pilot control member (70) is pretensioned so that in the unlatched state it exerts a torque on the pilot finger (36), which completes its pivoting behind the front filter plate (2) independently of its resistance to motion. This ensures that the follow-up finger (56) is also reliably pivoted via the follow-up control member (80). <IMAGE>

Patent DE-4127270-A1 (DE)
Title: Appts. for classifying tobacco particles
Inventor: STUDT STEPHAN
IPC: A24B5/10
Filed: 1991-08-17
Abstract: Particles of fibrous material in a stream contg. a random mixt. of long and shorter particles, are classified, in appts.  which includes a vibratory conveyor with an elongate trough. The mixt. is introduced at one end of the trough and the longer particles are removed from the other. A number of longitudinal depressions are formed in the bottom wall of the trough to align the particles. The bottom wall also has at least one transverse slot to permit removal of the shorter particles. - More specifically, a vibratory conveyor comprises three parallel troughs including an upper trough, a lower trough and a lateral trough. The conveyor is vibrated via leaf springs  connected to a frame and eccentrics. A mixed stream of particles of tobacco is fed to the left-hand end of the trough. The bottom wall of the trough has sections, the major part having elongate channels. The longer particles of the mixture become aligned in these channels. Transverse to the channels are slots, pref. angled to the sides of the trough towards an opening in the trough sidewall connected with the lateral trough. Each slot is bounded by a downstream surface which is smooth and angled so that the slot widens in a downward direction. The upstream ends of the  sections include smooth portions immediately downstream of slots. In use, the longer particles travel along the grooves to the outlet end. Shorter particles fall into the slots and most pass through to the lower trough from where they are delivered via apertures to a hopper. Other shorter particles are trapped by the surface and slide along to enter the lateral trough. This prevents blocking of the slots.
