Abstract: Cigarettes or like rod-shaped articles are conveyed sideways in equidistant flutes of a rotary drum at a speed of at least one thousand articles per minute and along an ejecting station having a width which substantially exceeds and can be a multiple of the distance between a pair of neighboring flutes. Selected articles are ejected from their flutes in response to electric or pneumatic signals by being subjected to the action of a mechanical force and/or to the action of a force produced by a stream of gaseous fluid whereby the point of application of the force moves with the flute which contains the respective selected article while such flute travels through the ejecting station. The articles can be held in their flutes by suction or by mechanical means, and the suction or the mechanical retaining action is terminated when a selected article reaches the ejecting station so that the selected articles are separated under the action of gravity and/or under the action of centrifugal force.

Abstract: A lip extender for use with a loading dock leveler. The lip extender includes a lower link connected at its lower end to the base plate of the leveler and a toggle arm connected at its upper end beneath the lip. The opposite ends of the toggle arm and lower link are pivotally connected together. Upward movement of the hinge connection between the bridge plate and lip moves them both upwardly to a cocked position in which they are supported by the toggle arm and lower link, which pivot into an over-center position. Downward force exerted on the upper part of the bridge plate causes a cam follower carried by the pivotal connection between the toggle arm and lower link to engage a cam surface mounted beneath the bridge plate. The lip is thereby extended simultaneously upwardly and outwardly over the rear edge of a truck disposed adjacent to the dock. When the lip reaches its fully extended position, the toggle arm moves past the center position and allows the lip to drop onto the truck bed.

Abstract: Automatic machinery for performing multiple operations on different parts of workpieces includes an incrementally rotating, workpiece supporting turret provided with three workpiece supports. Upon rotating of the turret, a workpiece loaded on a support located at a first position is indexed about the axis of the turret to a second position at which a first operation is performed thereon, then to a third, idle position. Continued rotation of the turret results in an index of the workpiece to the first position, then again to the second position at which a second operation is performed thereon. After the next index to the third position, the workpiece is unloaded from the support. As the turret is indexed, the workpiece is rotated relative to the turret whereupon the workpiece is oriented differently each time it reaches the second position causing the operations to take place on different parts of the workpiece.

Abstract: This upstroke-cushioning expansible strut consists of a spring-pressed hollow upper inner arm having on its lower end a piston head reciprocable within a roughly cylindrical hollow lower outer arm, the former being pivoted to an automobile rear hatch while the latter is pivoted to the lower part of the automobile body. Mounted between the lower arm and the upper arm is an elongated hollow spool-shaped internal seal which also guides the upper arm as it is propelled upward by the lifting force applied by the operator, assisted by internal springs. The air is allowed to escape gradually through bleed orifices until the upper arm nears its fully extended position, whereupon the release of the air is halted by the covering up of the orifices by the internal seal when said orifices reach said seal, thereby cushioning the impact which would otherwise occur between the piston head on the lower end of the upper inner arm and the upper end of the lower outer arm. The internal seal also acts as a resilient stop.
