摘要:
Apparatus for the separation of heavy and light particles from material which includes means for fluidising and agitating the material to cause heavy particles to sink from the acceptable material and comprising a deck adapted to receive material at a reception end and means for vibrating said deck to cause the material to move longitudinally along it to a discharge end, said deck having a number of longitudinally extending troughs separated by peaks and means for providing an upwardly directed air flow in the troughs characterised by means for causing two or more stratified material separation zones in each trough to classify the material two or more times.
摘要:
Fibrous materials are opened from a metered flow thereof using an opening roller and are subjected to a controlled and adjustable further opening operation to input desirable properties to the fibers. The invention is particularly described with respect to cut tobacco fibers and glass fibers.
摘要:
La présente invention se rapporte à un filtre (14) pour la fumée du tabac, qui produit une courbe de libération du goudron plus uniforme sans chute de pression inacceptable en amenant la fumée de la cigarette à suivre un trajet d'écoulement progressivement plus long à travers un cylindre externe (20) en matériau d'étoupe de filtre à résistance élevée à l'écoulement, avant de passer radialement vers intérieur à travers un cylindre (24) en fibres microfines en suivant un trajet d'écoulement à faible résistance (26) jusque dans la bouche du fumeur. L'augmentation progressive du trajet d'écoulement a pour résultat un engorgement progressif du cylindre en fibres microfines par le matériau filtré au fur à mesure que la cigarette est fumée.
摘要:
Packaging for smoking articles such as cigarettes in a rigid, hinged-lidded, carton (50) includes a sealed barrier layer enclosure (52) within the carton and having a line of separation aligned with a lid-end edge of an inner frame (56) of the carton so that the edge acts as a guide in shearing the barrier layer when opening the enclosure.
摘要:
A cigarette or cigar comprising a rod of tobacco which decreases in strength from the kindled end to the other end and which is provided with a filter, the filtration efficiency of which increases as the cigarette is consumed.
摘要:
A container having substantially parallel walls (2-5) and openable closure (8) means for at least one end (7), said closure means comprising at least three closure flaps (30,31) pivoted to a slidable sleeve (9) surrounding said side walls (3-5) and operating means which close said flaps when said sleeve is moved to a first position and which open said flaps to reveal the interior of the container when the sleeve is moved to a second position.
摘要:
Apparatus for the separation of heavy and light particles from particulate material which includes means for fluidising and agitating the material to cause heavy particles to sink from the acceptable material and comprising a deck adapted to receive material at a reception end and means for vibrating said deck to cause the material to move longitudinally along it to a discharge end, said deck having a number of longitudinally extending troughs separated by peaks and providing an upwardly directed air flow in the troughs characterised by control means for causing the velocity of the upwardly directed fluidising air in each trough to initially increase to a point below the peaks and to then continue upwards at a reducing velocity.
