| 20120085491 | Infrared Plastic Welding With Recirculation Of Unabsorbed Infrared Laser Light To Increase Absorption Of Infared Laser Light - Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated in an infinite loop back to the low absorption weld interface for reabsorption in the process. On each pass in the infinite loop, more infrared laser light is absorbed at the weld interface. | 04-12-2012 |
| 20120073414 | ULTRASONIC SYSTEM AND METHOD FOR CUTTING SOFT MATERIALS AND ULTRASONIC HORN BLADE THEREFOR - An ultrasonic system and method for cutting soft material has an ultrasonic transducer that vibrates axially at least one horn blade having a serrated edge so that when the horn blade is moved into the food product being cut, it is vibrating in a direction in and out of the food product to make a plunge cut. | 03-29-2012 |
| 20100224327 | PART SENSING HORN - A nodal sensing horn assembly for use in ultrasonic welding a first part to a second part that includes a nodal horn, a cavity formed within the nodal horn, and a sensing device at least partially disposed within the cavity. The sensing device senses a property, such as presence and/or orientation, of the first part and outputs a sensing signal in response thereto. | 09-09-2010 |
| 20100206487 | ULTRASONIC VIBRATION WELDER - The present invention solves the problem that a connecting portion between a horn and a vibration transmission rod has a tendency to get damaged and the problem associated with the structure in which a chip is attached to an end of the vibration transmission rod, which occur with the known ultrasonic vibration welder. A vibration transmission rod has an end surface serving as a vibration-and-pressure application surface, and a polygonal cross section. The vibration transmission rod is disposed at an end of a horn in such a manner that they vibrate together. The vibration transmission rod and a mass are formed separately. The mass applies pressure to a projection formed at a nodal point of the vibration transmission rod. | 08-19-2010 |
| 20100176184 | ULTRASONIC WELDING USING AMPLITUDE PROFILING - A method of ultrasonic welding aluminum parts together includes placing the aluminum parts in an ultrasonic welding apparatus and contacting at least one of the aluminum parts with a horn tip of a weld horn of the ultrasonic welding apparatus. A weld amplitude is profiled during a weld cycle of the ultrasonic welding apparatus by producing a high weld amplitude above 55 μm at the horn tip of the weld horn during an initial period of a weld cycle and producing a low weld amplitude below 55 μm at the horn tip after the initial period. | 07-15-2010 |
