Abstract: A gas pressure operated dispensing method and apparatus for dispensing fluids including a first container as a primary fluid source, a second container as a reserve fluid source, a first gas line connected to the first container and a second gas line connected to the second container, a gas pressure source connected to the first and second gas lines for supplying a pressurized gas thereto, a first change over valve and a second change over valve disposed in the first gas line and the second line, respectively, a supply line for introducing a fluid into the second container, a discharge line for discharging a fluid from the first container, a fluid line communicating with the supply line and the second container at one end and the discharge line and the first container at the other end, the fluid line containing a third valve, and vent line selectively connectible to the second gas line through the second change over valve when the gas pressure source is separated from the second gas line by the second change

Abstract: A charging device for opening and delivering leaf-type material which includes a conveyor having an upper surface along which leaf-type material moves in a downstream direction of travel toward a discharge end, an opening mechanism adjacent the discharge end for establishing an arcuate path of travel along which a plurality of members move for intermittently successively underengagingly contacting and opening the leaf-type material during the movement thereof beyond the discharge end, and at least one mechanism downstream of the opening mechanism for establishing an arcuate path of travel along which a plurality of elements move for intermittently successively contacting and stripping, in opposition to the downstream direction of travel, the leaf-type material, and both the opening and stripping mechanisms being formed by a plurality of arcuately spaced elongated bars carried by end plates rotatable about associated axes in identical directions.
