Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
Cigarette-holder or pipe stem comprising an elongated body having an upstream end and a downstream end and containing an ultrasonic tobacco smoke treatment device comprising an elongated duct disposed eccentrically in relation to the longitudinal axis of the body having an inlet end to receive the products of tobacco combustion from the upstream end of said body and an outlet end to deliver treated products of combustion to the downstream end of the body, an ultrasonic vibration generator disposed in said duct to generate sound waves transverse to the direction of flow through the duct, said ultrasonic vibration generator comprising a piezoelectric ceramic element driven by an LED integrated circuit power oscillator, and a battery to energize said circuit, said ceramic element forming a portion of the wall of said duct.
Claim 2
Dependent Claim
131 words
Cigarette-holder or pipe stem comprising an elongated body having an upstream end and a downstream end and containing an ultrasonic tobacco smoke treatment device comprising an elongated duct disposed eccentrically in relation to the longitudinal axis of the body having an inlet end to receive the products of tobacco combustion from the upstream end of said body and an outlet end to deliver treated products of combustion to the downstream end of the body, an ultrasonic vibration generator disposed in said duct to generate sound waves transverse to the direction of flow through the duct, said ultrasonic vibration generator comprising a piezoelectric ceramic element driven by an LED integrated circuit power oscillator, and a battery to energize said circuit, said ceramic element forming a portion of the wall of said duct.
Claim 3
Dependent Claim
29 words
Cigarette-holder or pipe stem as recited in claim 1, wherein said ceramic element has a parallelipipedic configuration with its major dimension extending in the longitudinal direction of the duct.
Claim 4
Dependent Claim
29 words
Cigarette-holder or pipe stem as recited in claim 1, wherein said ceramic element consists of a cylinder having its longitudinal axis parallel to the longitudinal axis of said duct.
Claim 5
Dependent Claim
27 words
Cigarette-holder or pipe stem as recited in claim 1, wherein said duct exposed to ultrasonic pressures is disposed downstream of an expansion chamber disposed in said body.
Claim 6
Dependent Claim
34 words
Cigarette-holder or pipe stem as recited in claim 4, wherein said expansion chamber is disposed downstream of a diffuser-accelerator disposed in said body consisting of a plurality of capillary or similar grooves or channels.
Claim 7
Dependent Claim
67 words
Cigarette-holder or pipe stem as recited in claim 1, wherein said body comprises at least two tubular sections adapted to rotate in relation to each other, wherein one of said tubular sections encloses said duct, the other tubular section comprising an orifice leading to the downstream end of the body, said duct and orifice communicating with each other in a given relative position of said tubular sections.
Claim 8
Dependent Claim
53 words
Cigarette-holder or pipe stem as recited in claim 6, wherein said two tubular sections incorporate co-operating contact means constituting a switch and adapted to close the circuit for energizing said integrated circuit in a given relative position of said tubular sections which corresponds to the mutual communication between said duct and said orifice.
Claim 9
Dependent Claim
46 words
Cigarette-holder or pipe stem as recited in claim 1, wherein said ultrasonic vibration generator comprises a piezoelectric nickel strip driven by an LED integrated circuit power oscillator, and a battery to energize said circuit, said nickel strip forming a portion of the wall of said duct.
