Abstract: This invention relates to the treatment of substrates with fluidized material in repetitive patterns during application cycles. The treatment patterns made with this invention can be altered by changing machine operating parameters. The patterns of fluidized material are applied to substrates using an applicator drum. Machined in the outer surface of the applicator drum are a plurality of slots filled with deformable material. The deformable material extends to a position in each slot just short of the outside diameter of the applicator drum, leaving a cavity in each slot. These cavities are filled with slurry in a slurry applicator unit. A compression drum mounted within the hollow interior of the applicator drum uses compression tips to displace the deformable material in each slot in succession beyond the periphery of applicator drum at a position adjacent to the substrate, causing the slurry in the cavity to be applied to the substrate.

Abstract: A method and apparatus for orienting elongated components, where the components are initially oriented in a random manner with respect to the ends of the components. Improperly oriented components are separated from properly oriented ones and are transferred to a turnaround device; this device rotates the improperly oriented components 180.degree. about a transverse axis running from one end of the component to the other end of the component. The stream of rotated elongated components is then reintegrated with the stream of elongated components which were initially properly oriented. All of the elongated components are then removed from the orienting apparatus. The output stream of properly oriented elongated components coincides with the input stream of randomly oriented elongated components.

Abstract: A smoking article is provided in which a flavor-generating medium is heated electrically to release an aerosol for inhalation by a consumer. The smoking article includes a heater having resistive heating elements printed on a flexible substrate. The heater can be manufactured by circuit board mass production techniques, and can be formed to fit inside an article of the same shape and size as a conventional cigarette. Alternatively, the heater comprises an array of heating elements onto which charges of flavor-generating medium are deposited. The heating elements are connected in a manner which allows the temperature increase in the heater to be concentrated in individually selected heating elements, and requires a minimal number of electrical conductors.

Abstract: This invention relates to a method for delivering free-flowing material into discrete receiving spaces separating filter plugs in partially constructed cigarette filter assemblies. The method entails rapidly feeding a free flowing material such as charcoal into partially constructed cigarette filter assemblies. The free flowing material is dispensed to a first conveyance means and is subsequently transferred to a second conveyance means that is positioned parallel and above the first conveyance means. Vacuum is used to hold the free flowing particulate material onto the first conveyance means and is used to transfer the free flowing material to the second conveyance means and to hold it there. The free flowing material is next transferred into receiving spaces formed between articles such as cigarette filter plugs that are disposed on a third conveyance means. The transfer of the free flowing material to the receiving spaces may also be accomplished by use of vacuum or gravity.

Abstract: A modular system and method using the system for the high speed high resolution inspection of printed webs are provided. Each module inspects one lane of a printed web for print defects. Each gray scale or bipolar gray scale gradient pixel value of a digitally converted input image is compared to the minimum and maximum threshold values of the image template by a real-time digital signal processor. The image template is created in a secondary non-real-time processor by producing a statistical representation of a number of input images. The image template is desensitized to longitudinal and transverse jitter of the printed web so that jitter is not identified by the system as a print defect. The user is signaled if actual print defects exist and the lanes in which the defects exist are identified.

Abstract: A limited-life reusable hard pack for encasing a soft pack of cigarette. The reusable hard pack permits easy access to the cigarette by the feature of a sliceable interior wall attached to a pivotable bottom wall that when moved relative to the exterior walls of the hard pack pushes the soft pack upward and beyond the top of the hard pack. An overhang on a top wall extends across and beyond one side wall to prevent the bottom wall from pivoting downward, beyond the bottom plane of the hard pack. The opposite side of the top wall leaves a gap through which cigarette may be removed without opening to top closure. One such hard pack is collapsed and inserted into a standard ten-pack carton.

Abstract: This invention provides smoking compositions which contain a novel .beta.-hydroxycarboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases .alpha.-hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

Abstract: One or more misaligned packaging blanks or blanks for cigarette boxes in a stack can be realigned by causing the stack to be engaged at both ends by two half-shell-shaped receiving portions. It is then tilted by 90.degree. so that the edges of the blanks all rest on a supporting surface. The two receiving portions are then brought together so as to realign any blanks protruding from the stack longitudinally. A detection device are incorporated in one of the receiving portions for checking the proper orientation of the stack and for causing it to be turned over one way or the other, depending upon its initial orientation.

Abstract: The present invention provides a flow liquid-phase chemical reaction system in which a high pressure reservoir unit holds a solvent solution which contains an organic reactant and a gas reactant. The quantity of gas reactant dissolved in the solvent solution is determined by the level of gas reactant vapor pressure in the reservoir unit. The solvent solution is passed through a solid catalyst reactor unit to achieve a selective reaction between the two reactant components of the solvent solution.
