Abstract
Abstract A magnetic agitator comprises a magneic agitator element (3) in a magnetically permeable vessel (1), and a magnetic rotating plate (5) rotatably fixed to the bottom of said vessel. The magnetic type agitator further comprises a thin ultrasonic vibrating element (4) fixed to the bottom of the said vessel, said magnetic rotating plate being placed so as to to permit the magnetic force from said magnetic rotating plate to have an effect on said magnetic agitator element, thereby permitting simultaneous agitation and ultrasonic vibration of said liquid in said vessel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
A magnetic type agitator comprising a magnetically permeable vessel (1), a magnetic agitator element (3) adapted to be placed therein, and a magnetic rotating plate (5) rotatably fixed within a base (2) beneath said vessel, whereby agitation of liquid (A) inside said vessel may be effected by rotating said magnetic rotating plate (5), characterized in that an ultrasonic vibrating element (4) is fixed to the bottom of said vessel (1), thereby permitting simultaneous agitation and ultrasonic vibration of said liquid in said vessel.
Claim 2
Dependent Claim
83 words
A magnetic type agitator comprising a magnetically permeable vessel (1), a magnetic agitator element (3) adapted to be placed therein, and a magnetic rotating plate (5) rotatably fixed within a base (2) beneath said vessel, whereby agitation of liquid (A) inside said vessel may be effected by rotating said magnetic rotating plate (5), characterized in that an ultrasonic vibrating element (4) is fixed to the bottom of said vessel (1), thereby permitting simultaneous agitation and ultrasonic vibration of said liquid in said vessel.
Claim 3
Dependent Claim
60 words
An agitator according to claim 1 wherein said vessel (1) has an inner container (21), said container (21) containing said liquid (A), and said magnetic agitating element (3) being placed in use in said container (21), the annular space between said vessel (1) and said container (21) being filled with a medium (B) which permits transmission of an ultrasonic wave.
Claim 4
Dependent Claim
19 words
An agitator according to claim 1 or 2 wherein said ultrasonic vibrating element (4) is an electrostriction vibrating element.
Claim 5
Dependent Claim
21 words
An agitator according to any preceding claim comprising a plurality of vessels (1) each having a respective ultrasonic vibrating element (4).
Claim 6
Dependent Claim
20 words
An agitator according to any preceding claim wherein said vessel (1) is integrally formed with the base of said agitator.
Claim 7
Dependent Claim
16 words
An agitator according to claim 5 comprising a plurality of containers (21) in a single vessel.
