Abstract
Abstract An ultrasonic cleaning system in which at least one transducer unit includes a base bonded to the bottom of a cleaning tank each unit including a stud on which are placed two annular transducer elements, a pressure plate, and a nut. The stud is firmly fixed by tapered threads to the base so that removal of the compression nut does not disturb the stud but allows replacement of defective transducer elements. Pairs of the transducer units are associated with a single plug-in oscillator unit which supplied high frequency vibratory energy to it.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
An ultrasonic cleaning system having receptacle mEans for retaining liquid which is agitated ultrasonically comprising, a plurality of transducer means for converting electrical energy to mechanical vibratory energy each including a base integrally mounted on said receptacle, a transducer element mechanically coupled to said base and having terminal means for coupling to a source of electrical energy, fastener means for coupling said transducer element to said base said fastener means having a portion thereof removable to allow said transducer element to be replaced said portion being reusable to recouple a transducer element to said base, and a source of electrical energy including a plurality of separate oscillator means each mounted in separate plug-in units associated respectively with each of said transducer means, each of said oscillator means being coupled to respective terminals of said transducer means.
Claim 2
Dependent Claim
136 words
An ultrasonic cleaning system having receptacle mEans for retaining liquid which is agitated ultrasonically comprising, a plurality of transducer means for converting electrical energy to mechanical vibratory energy each including a base integrally mounted on said receptacle, a transducer element mechanically coupled to said base and having terminal means for coupling to a source of electrical energy, fastener means for coupling said transducer element to said base said fastener means having a portion thereof removable to allow said transducer element to be replaced said portion being reusable to recouple a transducer element to said base, and a source of electrical energy including a plurality of separate oscillator means each mounted in separate plug-in units associated respectively with each of said transducer means, each of said oscillator means being coupled to respective terminals of said transducer means.
Claim 3
Dependent Claim
26 words
An ultrasonic cleaning system as in claim 1 in which said bases are affixed to said receptacle by a bonding process in which heat is applied.
Claim 4
Dependent Claim
31 words
An ultrasonic cleaning system as in claim 1 in which said fastener means includes a stud having a removable nut and in which said base is threaded to receive said stud.
Claim 5
Dependent Claim
29 words
An ultrasonic cleaning system as in claim 1 in which each of said oscillator means includes indicator means for indicating a malfunction of such oscillator or associated transducer means.
Claim 6
Dependent Claim
133 words
Ultrasonic cleaning apparatus comprising, a base having a relatively substantial mass and a predetermined depth, a transducer element mechanically coupled to said base and having terminal means for coupling to a source of electrical energy, fastener means for coupling said transducer element to said base including a threaded stud having one end screwed into said base less than one-half said depth by application of a predetermined torque said fastener means including a pressure plate which in conjunction with said base forms a sandwich construction with said transducer element there between said stud extending through apertures in said transducer element and pressure plate and including nut means screwed onto the other end of said stud by application of a torque less than said predetermined torque to mechanically couple said transducer element to said base.
Claim 7
Dependent Claim
133 words
Ultrasonic cleaning apparatus comprising, a base having a relatively substantial mass and a predetermined depth, a transducer element mechanically coupled to said base and having terminal means for coupling to a source of electrical energy, fastener means for coupling said transducer element to said base including a threaded stud having one end screwed into said base less than one-half said depth by application of a predetermined torque said fastener means including a pressure plate which in conjunction with said base forms a sandwich construction with said transducer element there between said stud extending through apertures in said transducer element and pressure plate and including nut means screwed onto the other end of said stud by application of a torque less than said predetermined torque to mechanically couple said transducer element to said base.
Claim 8
Dependent Claim
21 words
Apparatus as in claim 5 where said base is cylindrical and said stud is centered on the axis of said base.
Claim 9
Independent Claim
120 words
A method of providing an ultrasonic cleaning system having receptacle means for retaining liquid which is agitated ultrasonically and having a transducer unit with a base to which is coupled an annular transducer element by a threaded stud, pressure plate and nut comprising the steps of, providing a threaded receptacle in said base, screwing said stud into said threaded receptacle by application of a predetermined torque, thereafter bonding said base to said receptacle means, placing said annular transducer element on said base with said stud extending therethrough, mechanically coupling said element to said base by placing said pressure plate on said element and said nut on said stud and applying a torque to said nut less than said predetermined torque.
Claim 10
Independent Claim
120 words
A method of providing an ultrasonic cleaning system having receptacle means for retaining liquid which is agitated ultrasonically and having a transducer unit with a base to which is coupled an annular transducer element by a threaded stud, pressure plate and nut comprising the steps of, providing a threaded receptacle in said base, screwing said stud into said threaded receptacle by application of a predetermined torque, thereafter bonding said base to said receptacle means, placing said annular transducer element on said base with said stud extending therethrough, mechanically coupling said element to said base by placing said pressure plate on said element and said nut on said stud and applying a torque to said nut less than said predetermined torque.
Claim 11
Dependent Claim
24 words
A method as in claim 7 in which the bonding force holding said base to said receptacle means is less than said predetermined torque.
Claim 12
Dependent Claim
43 words
A method as in claim 7 in which said base is bonded to said receptacle at a temperature greater than the Curie point of said transducer element and said element is placed on said base with said base at a substantially lower temperature.
