    摘要: This invention provides a dispensing assembly which is adapted to deliver two separate instantaneously coreactive liquid streams into an external contacting zone. The two reactants do not make contact within the body of the dispensing assembly, which prevents solid product formation and clogging within the dispensing assembly nozzles.The dispensing assembly is suitable for the coreaction of liquid carbon dioxide and liquid ammonia to produce free-flowing ammonium carbamate powder having a purity of substantially 100 percent.

    摘要: Material is collected in radially extending slots opening into the outer periphery of a first wheel intermittently rotated about a first axis to successively dispose material-containing slots at a registration location. A second wheel is rotated synchronously with the first wheel about an axis perpendicular to the first axis to successively dispose slots extending axially therein at the registration location. Material is forcibly discharged from the first wheel slots to the second wheel slots as they are maintained in stationary facing relation at the registration location.

    摘要: A method and apparatus are provided for applying an adhesive or flavoring solution to the coal end of a cigarette by means of a precisely controlled liquid jet spray to bond shreds of tobacco in the cigarette end and to thereby reduce the amount of tobacco which falls out of the cigarette when shaken. Electronic controls are employed to synchronize the formation and charging of a series of droplets which are deflected in prescribed paths to contact the coal end of the cigarette in a predetermined pattern. Circuits are provided to adjust the timing and phase of the charging mechanism to compensate for variations in the speed at which the cigarette is conveyed to a target area and for variations in the timing of droplet formation.

    摘要: In the course of continuous transport of filamentary material, mutually spaced portions thereof are selectively stretched, yielding articles having a longitudinal profile varying in filamentary material volume and of essentially constant filament density per unit volume. In producing cigarette filters, additive material is applied to the stretched material portions.
