  • Patent number: 8813758
    Abstract: The present invention is a combined smoking/vaporizing, grinding and storage implement used for inhaling burning or vaporized herb, tobacco or other plant material. The implement has an end around which serrated saw like teeth are located. The serrated teeth are bent slightly inward. When the implement is placed in a container of herb, tobacco or other plant material and is torqued, the teeth grind it into smaller pieces that are caught within the teeth such that the ground material eventually can fill up a compartment located within the implement and are enclosed therein by the teeth. An alternate embodiment further comprises a filter on the inhalation end for filtering the smoke or vapor caused by the burning or vaporizing of the ground material.

A weak organic acid and a pH adjusted inorganic ester salt are encapsulated in a matrix material which is in contact with the tow. The pH adjusted inorganic ester salt has a pH less than or equal to 8. When the cigarette filter is discarded into the environment, water liberates the weak acid and the ester salt from the matrix material. The weak acid hydrolyzes the ester liberating a strong acid. The strong acid catalyzes the degradation of the cellulose acetate tow. (The weak acid also hydrolyzes the cellulose acetate tow, but after the strong acid is generated, the strong acid becomes the dominant acid catalyst for the cellulose acetate tow degradation.

    Abstract: A system (100) and method for managing communication session is provided. The system includes a mobile node (104) that is communicably coupled to a first communication network (102). Further, the system includes a first proxy-relay (108). The first proxy-relay is communicably coupled to the first communication network and performs one or more functions on behalf of the mobile node. The system also includes a first policy-profile repository (106) that is communicably coupled to the first communication network. The first policy-profile repository stores a first set of policy-profile definitions describing a first set of services in the first communication network that the mobile node is allowed to access and a first set of rules describing discovery preferences for the mobile mode.

  • Patent number: 7784470
    Abstract: A smoking article such as a cigarette comprises a tobacco rod and a filter component having a cavity filled with spherical beaded carbon. As mainstream tobacco smoke is drawn through the filter component, targeted gas phase smoke constituents are removed as the smoke passes through the carbon. During the filter manufacturing process the spherical beaded carbon flows like a liquid and substantially completely fills the cavity. Point-to-point contact between the spherical beads together with substantially complete filling of the cavity produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads during smoking.

  • Publication number: 20100206317
    Abstract: Reduced risk tobacco-related products and methods of use. These tobacco-related products (e.g., cigarettes or filters) are designed to reduce the biological insult, for example, DSBs, cell death or perturbation of RNA transcriptome or proteome as compared to the amount of biological insult induced by another cigarette, such as a conventional or reference cigarette (e.g., 2R4F), in human cells, and to provide a reduced risk cigarette that meets a cigarette smoker's sensory/perception needs.

  • Publication number: 20100206318
    Abstract: The invention relates to a cigarette holder-type component, which is intended to be attached to a tobacco product and can be adapted to the suction head of the tobacco product so that the smoke travels through the component during smoking. The component contains porous material, into which an aqueous solution containing at least one aldehyde-binding compound has been absorbed to form an aldehyde-binding filter. In the component that is to be attached to the tobacco product, the water content of the material is kept at a level where the aldehyde-binding compounds are capable of reacting with the aldehydes in the smoke, changing them into a harmless form.

  • Patent number: 7690385
    Abstract: An electrically heated cigarette smoking system includes a cigarette that is formed with a tobacco rod portion, a filter tube portion, a tobacco mat layer wrapped around the tobacco rod portion and the filter tube portion with opposite ends of the tobacco mat layer abutting along a seam parallel to the central axis of the cigarette and cigarette paper wrapped around the tobacco mat layer and bonded to itself along an overlapped seam that is offset from the seam of the tobacco mat layer. The method of manufacturing the cigarette includes wrapping the tobacco mat layer and the cigarette paper around the tobacco rod portion and the filter tube portion on a single, high-speed machine.

  • Publication number: 20100006112
    Abstract: Provided is a cigarette filter and method of making the filter. The filter includes an adsorbent dispersed within the filter and a downstream plug of randomly-oriented fibers. The randomly-oriented fibers mechanically capture adsorbent particles entrained in tobacco smoke. One or more plugs of axially-oriented fibers may also be located upstream and/or downstream of the adsorbent, and are included in an amount sufficient to adjust the length of the filter.

  • Patent number: 7614402
    Abstract: The invention is directed to a simulated cigarette for use as a smoking cessation aid comprising a cylindrical member having a predetermined size and shape and a filter member formed at one end of the cylindrical member. The filter member has a predetermined size and shape capable of being comfortably held between a user's lips. An opening is formed within the end of the filter member that is held between the user's lips. A hollow portion is formed within at least the filter member. Flavoring, such as peppermint or spearmint, is placed within the hollow portion. Upon the application of pressure to the filter member, the flavoring is dispersed through the opening of the filter member and into the user's mouth to aid in the reduction of the user's urge for a cigarette.

  • Patent number: 7610920
    Abstract: Smoking articles which use thiol-functionalized sorbents are provided. The thiol-functionalized sorbents comprise at least one thioalkylsilyl compound covalently bound to an inorganic molecular sieve substrate, where the thiol-functionalized sorbent is capable of removing at least one heavy metal constituent of mainstream smoke. The thiol-functionalized sorbents are particularly useful for the removal of mercury and/or cadmium from mainstream smoke. Methods for making cigarette filters and smoking articles using the thiol-functionalized sorbent, as well as methods for smoking a cigarette comprising the thiol-functionalized sorbent, are also provided.
