Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A METHOD OF JOINING MATERIALS, AT LEAST ONE OF WHICH IS FUSIBLE, WITH THE AID OF A FORCE-APPLYING MEMBER HAVING A NARROW CONTACT EDGE OF SUBSTANTIAL EXTENT RELATIVE TO ITS WIDTH, SAID CONTACT EDGE BEING SLOTTED TO PROVIDE A PLURALITY OF SEGMENTS, COMPRISING THE STEPS OF OVERLAPPING SAID MATERIALS IN CONTACT WITH EACH OTHER, POSITIONING SAID MEMBER SUCH THAT SAID CONTACT EDGE APPLIES A SMALL COMPRESSIVE FORCE TO SAID MATERIALS ALONG A LINE TRAVERSING THE AREA OF OVERLAP, VIBRATING THE CONTACT EDGE OF SAID MEMBER AT AN ULTRASONIC RATE TO APPLY AN ADDITIONAL RECURRING FORCE TO SAID MATERIALS ALONG SAID LINE WITH SAID RECURRING FORCE HAVING A FIRST SUBSTANTIAL COMPONENT NORMAL TO THE SURFACES OF SAID MATERIALS AND A SECOND SUBSTANTIAL COMPONENT PERPENDICULAR TO SAID EDGE AND PARALLEL TO SAID SURFACES, AND SIMULTANEOUSLY OSCILLATING SAID MEMBER IN THE DIRECTION IN WHICH SAID CONTACT EDGE EXTENDS TO CORRESPONDINGLY MOVE THE SEGMENTS THEREOF OVER A FINITE DISTANCE IN SAID DIRECTION, WHEREBY SAID MATERIALS ARE JOINED WITHIN THEIR AREA OF OVERLAP.
Claim 2
Independent Claim

Claim 3
Dependent Claim
155 words
IN APPARATUS FOR SEALING TWO LAYERS OF THERMOPLASTIC MATERIAL TO EACH OTHER BY THE APPLICATION OF ULTRASONIC ENERGY, A UNITARY VIBRATORY MEMBER CAPABLE OF SUPPORTING VIBRATIONS AT AN ULTRASONIC FREQUENCY COMPRISING FIRST AND SECOND COAXIL CYLINDRICAL PORTIONS OF SUBSTANTIALLY DIFFERENT MASSES, THE COMBINED LENGTH OF SAID PORTIONS BEING EQUAL TO AN INTEGRAL NUMBER OF HALF-WAVELENGTHS OF SAID ULTRASONIC FREQUENCY IN SAID MEMBER; SAID PORTIONS MEETING SUBSTANTIALLY AT A NODAL PLANE OF VIBRATION IN SAID MEMBER, MEANS TO IMPART ULTRASONIC VIBRATION IN SAID MEMBER, MEANS TO IMPART ULTRASONIC VIBRATIONS LONGITUDINALLY OF SAID MEMBER TO THE END SURFACE OF SAID FIRST PORTION, AND A RELATIVELY THIN CYLINDRICAL CONTACT EDGE FORMED AT THE END SURFACE OF SAID SECOND PORTION AND BEING DIVIDED INTO A PLURALITY OF INDIVIDUAL SEGMENTS OF EQUAL ARCUATE LENGTH BY A PLURALITY OF NARROW EQUALLY SPACED SLOTS PROVIDED THEREIN; THE INDIVIDUAL SEGMENTS OF SAID CONTACT EDGE ADAPTED TO VIBRATE WITH COMPONENTS OF OF SAID MEMBER.
Claim 4
Dependent Claim
155 words
IN APPARATUS FOR SEALING TWO LAYERS OF THERMOPLASTIC MATERIAL TO EACH OTHER BY THE APPLICATION OF ULTRASONIC ENERGY, A UNITARY VIBRATORY MEMBER CAPABLE OF SUPPORTING VIBRATIONS AT AN ULTRASONIC FREQUENCY COMPRISING FIRST AND SECOND COAXIL CYLINDRICAL PORTIONS OF SUBSTANTIALLY DIFFERENT MASSES, THE COMBINED LENGTH OF SAID PORTIONS BEING EQUAL TO AN INTEGRAL NUMBER OF HALF-WAVELENGTHS OF SAID ULTRASONIC FREQUENCY IN SAID MEMBER; SAID PORTIONS MEETING SUBSTANTIALLY AT A NODAL PLANE OF VIBRATION IN SAID MEMBER, MEANS TO IMPART ULTRASONIC VIBRATION IN SAID MEMBER, MEANS TO IMPART ULTRASONIC VIBRATIONS LONGITUDINALLY OF SAID MEMBER TO THE END SURFACE OF SAID FIRST PORTION, AND A RELATIVELY THIN CYLINDRICAL CONTACT EDGE FORMED AT THE END SURFACE OF SAID SECOND PORTION AND BEING DIVIDED INTO A PLURALITY OF INDIVIDUAL SEGMENTS OF EQUAL ARCUATE LENGTH BY A PLURALITY OF NARROW EQUALLY SPACED SLOTS PROVIDED THEREIN; THE INDIVIDUAL SEGMENTS OF SAID CONTACT EDGE ADAPTED TO VIBRATE WITH COMPONENTS OF OF SAID MEMBER.
Claim 5
Dependent Claim
73 words
IN APPARATUS FOR FORMING A BOND BETWEEN TWO OR MORE PIECES OF SHEET MATERIAL BY THE APPLICATION OF ULTRASONIC ENERGY, A VIBRATORY MEMBER CAPABLE OF SUPPORTING VIBRATIONS AT AN ULTRASONIC FREQUENCY, AN EXTENDED, NARROW, CONTACT EDGE FORMED ON SAID MEMBER ADAPTED TO VIBRATE WITH ORTHOGONALLY RELATED COMPONENTS OF MOTION, AND A CUTTING EDGE EXTENDING BEYOND SAID CONTACT EDGE FOR SERVING SAID SHEET MATERIAL ALONG A LINE ADJACENT THE BOND TO BE FORMED THEREBETWEEN.
Claim 6
Dependent Claim
73 words
