Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
The method of separating a thermoplastic or similar molded part from a runner, said molded part being attached to the runner by a gate comprising: providing a source of ultrasonic energy, and coupling said source to a portion of said runner, and said source providing energy of sufficient motional amplitude and intensity to cause a softening and burnout of the gate to obtain a separation of the molded part from the runner.
Claim 2
Independent Claim
72 words
The method of separating a thermoplastic or similar molded part from a runner, said molded part being attached to the runner by a gate comprising: providing a source of ultrasonic energy, and coupling said source to a portion of said runner, and said source providing energy of sufficient motional amplitude and intensity to cause a softening and burnout of the gate to obtain a separation of the molded part from the runner.
Claim 3
Independent Claim
108 words
The method of simultaneously degating a plurality of molded thermoplastic parts which are joined to a runner by respective gates comprising the steps of: disposing said parts while joined to the runner upon a base; providing a source of ultrasonic energy having a horn coupled thereto, the latter providing at an output surface thereof vibraTions having a motional amplitude in the range from 0.001 to 0.005 inch peak to peak, and coupling said output surface to said runner whereby to subject said runner to ultrasonic energy of substantially large motional amplitude to cause a burnout of the respective gates and freeing said parts from connection to said runner.
Claim 4
Independent Claim
108 words
The method of simultaneously degating a plurality of molded thermoplastic parts which are joined to a runner by respective gates comprising the steps of: disposing said parts while joined to the runner upon a base; providing a source of ultrasonic energy having a horn coupled thereto, the latter providing at an output surface thereof vibraTions having a motional amplitude in the range from 0.001 to 0.005 inch peak to peak, and coupling said output surface to said runner whereby to subject said runner to ultrasonic energy of substantially large motional amplitude to cause a burnout of the respective gates and freeing said parts from connection to said runner.
Claim 5
Dependent Claim
15 words
The method of degating as set forth in claim 2, said base including resilient material.
Claim 6
Dependent Claim
30 words
The method of degating as set forth in claim 2, coupling said output surface to said runner comprising urging said output surface in contact with a portion of said runner.
