The plunger moves up until index marks on the plunger indicate the desired amount of shortening has been extruded.

Abstract: The distributor of a cigarette rod making machine has an upright duct the upper end of which receives particles of tobacco from a magazine and the lower end of which has an outlet of variable cross-sectional area. The outlet is adjacent to the carding of a drum which withdraws from the duct a continuous layer of particles, and such particles travel toward a transversely extending barrier which is reciprocated in parallelism with the axis of the drum. The barrier has a grooved first surface which engages the exposed side of and homogenizes the layer, and a second surface which faces counter to the direction of movement of the drum and intercepts the surplus of particles whereby the intercepted particles pile up in front of the barrier. The pressure of piled-up particles is monitored by a sensor which causes a mechanical adjusting device to change the cross-sectional area of the outlet so that the area decreases when the pressure of piled-up particles increases, and vice versa.

Abstract: An overcap for use on dispensing containers which cap offers resistance to attempts by a child to dispense the contents from the container is disclosed. The overcap features an actuator mounted on the container dispensing stem, an outer shell which encloses the actuator and a U-shaped communicator which movably contacts, at its bottom end, the actuator and which has a portion of each vertical leg protruding through apertures in the outer shell. Pressing downward on both of the protruding legs simultaneously will depress the actuator and cause the contents of the container to be dispensed. Application of downward pressure on only one of the protruding legs will not result in depression of the actuator but rather only partial rotation of the communicator on the top of the actuator.
