International Classification:

A24C 550
D02J 122

US Classification:

93 1C

International Classification:

C07C12502

US Classification:

562555

Abstract:

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.

International Classification:

A24F 4700

US Classification:

131194

Abstract:

An electrical smoking article is provided in which tobacco flavor medium is carried past a heater by a continuous web. The web, which preferably is substantially non-combustible, may bear continuous tobacco flavor medium or spaced-apart portions of tobacco flavor medium. A flavor cassette for such an electrical smoking article is also provided. The cassette resembles a conventional recording tape microcassette, having the web in place of magnetic tape. The cassette may also include the heater past which the tape is indexed to heat individual portions of tobacco flavor medium.

International Classification:

A24F 4700

US Classification:

131329

Abstract:

A lighter is provided having a tobacco flavor heating system which includes a rotatable tobacco containing disc or spiral. This disc or spiral is registered in thermal proximity to a heating element and heated to generate tobacco flavors in response to a sensor. The disc and spiral are sized to provide a convenient number of puffs before disposal. Housings are provided for the disc and spiral to store, register and dispose the tobacco product efficiently. An induction heating system can be employed.

US Patent:

Filed:

Sep 20, 1988

Appl. No.:

7/246768

Inventors:

Robert T. Gaudlitz - Richmond VA
Hugh J. McCafferty - Midlothian VA
James M. Washington - Richmond VA

International Classification:

A24C 560

US Classification:

131284

Abstract:

A method and apparatus are provided for applying an adhesive 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.

Appl. No.:

5/585105

Inventors:

James M. Washington - Richmond VA
Emil A. Marx - Chester VA

Assignee:

Philip Morris Incorporated - New York NY

International Classification:

B65B 116
B65B 310

US Classification:

141 67

Abstract:

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.
