Abstract:
Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element (210) is in thermal proximity with the sleeve. The resistive heating element (210) is either a dedicated element or the cigarette heating elements (210). The sleeve serves as an aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element (210) is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.
Abstract:
A novel controller in an electrical smoking system and method, wherein the method includes the steps of: establishing a preferred thermal pathway to be executed with each heater activation responsively to a puff on an electrically heated cigarette; configuring a power cycle in accordance with the desired thermal pathway; dividing the power cycle into at least first and second phases each having a respective, predetermined time period and total energy input for each phase; and adjusting a respective duty cycle (or other power-adjusting factor) in each phase of the power cycle responsively to a voltage reading of the power source such that the established, respective total energy input of each phase is achieved during the time period of each power cycle.

A method and apparatus of manufacturing a web which is striped with add-on material, comprising: a first arrangement which establishes a sheet of base web from a first slurry and moves the established sheet along a first path; a second arrangement for preparing a second slurry; a moving orifice applicator operative so as to repetitively discharge the second slurry upon the moving sheet of base web, the moving orifice applicator comprising: a chamber box arranged to establish a reservoir of the second slurry across the first path; an endless belt having an orifice, the endless belt received through the chamber box; a drive arrangement operative upon the endless belt to continuously move the orifice along an endless path and repetitively through the chamber box, the orifice when communicated with the reservoir being operative to discharge the second slurry from the reservoir through the orifice; a flow distribution system for introducing the second slurry into the chamber box at spaced-apart feed locations along the chamber box; a flow monitoring system for reading fluid pressure at spaced-apart locations along the chamber box; and a controller arranged to identify which of the feed ports is operatively adjacent a monitored location of highest pressure variation, the controller selectively adjusting output of the flow distribution system at the identified feed location counteractively to the highest pressure variation, the controller adjusting output of a remainder of the feed locations counteractively to the output adjustment at the identified feed location.
Abstract:
An induction heating source (100) is provided for use with an electrical smoking article. The induction heating source provides an alternating electromagnetic field which inductively heats a susceptor in thermal proximity with tobacco flavor medium to generate aerosols. A plurality of induction heaters (102) are employed and/or the tobacco flavor medium is translated with respect to the induction heater or susceptor. The tobacco flavor medium can form an intimate structure with the susceptor and can take the form of a cylindrical cigarette or a web.
Abstract:
A method and an apparatus for controlling energy flow into a heating load array of a smoking article are provided. In response to a pressure drop in the mouthpiece of the smoking article, a selected load in the heating load array is switchably connected to a power supply. Energy delivered to the load is measured and the load is disconnected when a predetermined amount of energy has been delivered.
Abstract:
To produce a container with a rounded edge (13, 15, 17, 19), the container blank (10) is scored with several substantially parallel, laterally space score lines (30) adjacent the intended location of the rounded edge (13, 15, 17, 19). When the blank (10) is bent, a portion of the total deflection is absorbed by each score line (30) so that the resulting container edge is a gradual curve rather than a single sharp crease. The ends (32) of each scored region may be left unscored to further smooth the ends of the rounded container edge (13, 15, 17, 19). Methods and apparatus (110) for forming the above-described blank (10) are disclosed.
Abstract:
A polyolefin material having improved fibrillation properties, allowing one to achieve higher yield in cigarette filters made from the fibrillated material, includes between about 70 % and about 99 % of at least one polypropylene homopolymer with a melt index of between about 1.2 to about 3.0 (measured according to ISO standard 1133 at 230°C, 2.16 kgf) and a density of about 0.905 g/cc, and between about 1 % and about 30 % of at least one low density polyethylene homopolymer with a melt index of between about 0.9 and 3.0 (measured according to ISO standard 1133 at 190°C, 2.16 kgf) and a density of about 0.921 g/cc.
Abstract:
A novel photonic-electronic smoking system (21) comprising a cigarette (23) and a photonic operated electronic lighter (25), together with methodologies of smoking a cigarette, the lighter comprising a receptacle (27) for removably receiving a cigarette; a photonic source (96); an optical train establishing a plurality of optical pathways from said photonic source to a plurality of locations at the received cigarette; a source of electrical power (35A); a puff sensor (49) responsive to a drawing action upon a cigarette received by said receptacle; and a controller (41) responsive to said puff sensor for controllably communicating said source of electrical power with said photonic source so that upon drawing action upon the received cigarette, the photonic source discharges along said optical pathway to heat a region (110) of said cigarette adjacent at least one of said locations.
Abstract:
An aerosal is formed by supplying a material in liquid form to a tube (23) and heating the tube (23) such that the material volatizes and expands out of an open end (25) of the tube (23). The volatized material combines with ambient air such that volatized material condenses to form the aerosol. An apparatus (21) for generating such an aerosol, and a method for generating such an aerosol, are also disclosed.
Abstract:
A cigarette (23) comprises a tobacco rod having filled and unfilled portions arranged so that electrical heater elements (31) may overlap both portions. The rod includes a tubular tobacco web. The web is constructed by converting tobacco feedstock into a continuous sheet of tobacco web and converting the continuous sheet of tobacco web into one or ore bobbins of tobacco web suitable for automated manufacture of cigarettes. A heater (25) comprises a supporting hub and electrically resistive heater blades (37) defining a receptacle (27) for an inserted cigarette (23). Each blade comprises first and second heater blade legs each having a first end and a second end, and a connecting section connecting the second end of the first leg and the first end of the second leg. The blades (37) are heated by a resistive heating circuit and heat the inserted cigarette (23). The legs are separated by a gap to permit entrainment of flavour substances upon drawing.
