  • Patent number: 4999970
    Abstract: The making of cigarette packs is started by transferring arrays of cigarettes into successive pockets of a transporting unit while the pockets are at a standstill, and by inserting blanks into discrete pouches which are adjacent the front sides of the pockets. The pouches and the pockets are then accelerated, and the blanks are partially folded to overlie the arrays of cigarettes in the adjacent pockets prior to joint transfer of arrays and blanks into the receptacles of a continuously driven endless chain conveyor. The arms are then decelerated whereby the chain conveyor extracts the trailing portions of the blanks from their pouches and the blanks are converted stepwise into inner envelopes. The making of second envelopes around the inner envelopes can begin prior to or after completion of inner envelopes.

  • Patent number: 4729508
    Abstract: A hinged lid container for arrays of cigarettes is made of a one-piece blank and has a hollow body with an open end remote from its bottom wall, a collar which is integral with the front wall of the body at the open end and extends in part into the body, and a lid which is integral with the rear wall of the body. The collar has two lateral panels with rhomboidal portions extending beyond the respective sidewalls of the body. The free edges of the lateral panels are inclined with reference to the top wall of the lid when the latter is held in closed position so that its lateral walls abut the sidewalls of the body and are outwardly adjacent the rhomboidal portions of the lateral panels.

  • Patent number: 4227757
    Abstract: A safe for storage of paper money of different denominations has an armored housing whose top wall has a row of openings. The housing confines several indexible conveyors, one for each opening and each having a stack of drawers for storage of bills of a particular denomination. A drawer of each conveyor is held in register with the respective opening. When the drawer which registers with the corresponding opening is empty or contains a small number of bills, the teller actuates a starting switch to index the respective conveyor with a preselected delay which cannot be altered by the teller whereby the conveyor lifts a filled drawer into register with the associated opening. The delay for indexing of each conveyor can be selected independently of the other conveyors. A second starting switch is actuated by the teller to index the respective conveyor in the opposite direction, without delay, whereby the conveyor moves a filled drawer into the interior of the housing.

  • Patent number: 4078647
    Abstract: Blocks or streams consisting of one or more layers of cigarettes can be transported by one or more endless conveyors wherein an endless band-like or rim-like carrier is surrounded by a pile of elastically deformable bristles which engage and entrain the adjacent layer or layers of cigarettes when the conveyors are in motion. The conveyors may be used to evacuate selected blocks of arrayed cigarettes from a packing machine or to cooperate with each other or with conventional belt conveyors in order to transport cigarettes sideways to the inlet of the magazine in a packing machine.

  • Patent number: 3998637
    Abstract: Positive color diffusion transfer images are produced by a process that employs light-sensitive photographic elements containing dye-releasing redox agents. The dye-releasing redox agents may be a sulfonamido compound or a hydroquinone derivative which are capable of cleaving to release a diffusible color-providing moiety. A preferred process involves the use of black-and-white developer compositions and comprises1. developing only a negative silver image in the imagewise exposed areas of the photographic element;2. fogging the residual silver halide;3. developing the residual silver halide in the fogged element to silver and concurrently releasing a diffusible dye or dye precurser in the non-image, fogged silver halide areas; and4. at least a portion of the diffusible dye or dye precurser compound diffusing to a dye image-receiving layer.

  • Patent number: RE29042
    Abstract: A distributor for comminuted tobacco wherein a first conveyor, such as a carded drum, an endless apron or a pneumatic conveyor, supplies tobacco at a variable rate into the path of orbital movement of bristles on a rapidly rotating accelerating device. The bristles propel the particles of tobacco onto a narrow foraminous transporting belt which travels in a horizontal channel and accumulates a dense tobacco stream which is transported past a trimming device and into the wrapping mechanism of a cigarette rod making machine. The accelerating device is driven by a separate motor so that the peripheral speed of its bristles exceeds the speed of tobacco travel on the first conveyor. The stream is attracted to the transporting conveyor by suction, and the accelerating device is placed sufficiently close to the channel to insure that, during impact against the transporting conveyor or against the layer of tobacco thereon, the kinetic energy of all or nearly all tobacco particles is substantially identical.
