Abstract: A mass flow of cigarettes is reduced in width as it passes downwardly through chutes into a passage in which the cigarettes are formed as a stream two rows deep. The cigarettes are fed onto a fluted drum and accelerated to form gaps between them, the cigarettes in one row being held by suction in the flutes and those in the other row resting on top of them and being kept in place by suction. From the fluted drum the cigarettes are transferred to a further fluted drum as a single row, by being fed between a stripper and a fixed plate which are positioned so that only one cigarette, from each row alternately, can pass into a flute on the further drum. The cigarettes may then be collated into groups ready for packing.

Abstract: This invention relates generally to hydraulic and electrical systems for aircraft belt loaders and more particularly to such systems with interlocks to facilitate efficient and safe operation. The present invention provides a hydraulic and electrical system for battery powered aircraft belt loaders which precludes actuation of the electric traction drive motors when the brake is applied or set, or without the operator seat being occupied, which precludes actuation of the belt conveyor if the brake is not set, which controls conveyor run time and requires that the conveyor be reset to neutral before being actuated the hydraulic pump to permit power steering when the operator seat is occupied, and which requires that the directional control lever for traction drive be reset to neutral after demounting the seat before the electric traction drive motors can be energized.

Abstract: For belt conveyors in which the loaded part of the belt is supported by a gas layer in a trough, the energy needed to drive the belt is lower if the belt is more fully out of contact with the trough. But much energy is needed to compress the gas carrying the belt. The invention proposes to provide for measuring the power for these two purposes and to alter the gas flow into the trough so that the total power requirement is at a minimum. The latter may be performed in steps and as soon as a step appears to result in an increase of power required, this step may be undone. Drives of the belt (1) and of a compressor (6) by electric motors (5, 8) make measurement of electric power supplied thereto preferable. A control member (14) receives signals of power measurements and issues signals to change the power for drive of the compressor. Instead of separate measurements added by the control member (14) the latter may be fed with a measurement of the total power supplied for both purposes.

Abstract: For grasping, conveying and releasing printed products, particularly those occurring in a stream or scale flow by means of an endless link chain (90), a method is proposed, together with an apparatus having gripping and clamping members (10) for performing this method. For gripping and release purposes the individual gripping and clamping member (10) is so operated by means of control runner (70, 70') (75, 75') that a springy clamping arm (24) pressing under pretension against a bearing arm (16) is raised relative to the latter out of a closed position into an open position for grasping printed sheet (D) and then for conveying purposes is returned in snap-like manner into the closed position by the restoring force of clamping arm (24). The individual gripping and clamping member (10) operatively connected to articulation (92) of link chain (90) is constructed in one piece and has a substantially hairpin-like shape, which is bent four times.

Abstract: Can ends having an off-center aperture, are each orientated by a resiliently mounted peg which engages a surface of the can end and is rotated about a pitch circle for one complete revolution. The peg seeks and enters the aperture and thereafter causes the can end to rotate with it until it stops at a position corresponding to the desired orientation of the can end. The peg is then withdrawn from the aperture and the can end, supported in a carrier plate and is delivered to a moulding machine (not shown) in which a plastics closure is moulded into the aperture.

Abstract: Glass containers are pushed from an infeed conveyor through an arcuate path to a cross conveyor by pushers which have L-shaped fingers which are advanced to an advanced position to engage the containers and which can automatically reorient to maintain the container perfectly centered within the fingers until the container is displaced to a deposit location. The fingers are then pivotally displaced away from the container and subsequently repositioned at the advanced position.
