Patent CA-2543714-A1 (CA)
Title: Ultrasonic waterjet apparatus
Inventor: VIJAY MOHAN M
IPC: B05B15/00
Filed: 2003-11-03
Abstract: An ultrasonic waterjet apparatus (10) has a mobile generator module (20) and a high-pressure water hose (40) for delivering high-pressure water from the mobile generator module (20) to a hand-held gun (50) with a trigger and an ultrasonic nozzle (60). An ultrasonic generator in the mobile generator module (20) transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer (62) which vibrates to modulate a high-pressure waterjet flowing through the nozzle (60). The waterjet exiting the ultrasonic nozzle (60) is pulsed into mini slugs of water, each of which imparts a waterhammer pressure on a target surface. The ultrasonic waterjet apparatus (10) may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus (10) performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect A nozzle with multiple exit orifices or a rotating nozzle (76) may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient. A water dump valve (27) and controlling solenoid are located in the mobile generator module (20) rather than the gun (50) to make the gun lighter and more ergonomic.

Abstract: [PROBLEMS] To solve problems in a conventional lid opening device wherein it is uneconomical and requires a large storage space to prepare dedicated lid opening devices to open the lids of various cans and bottles sealed by different systems and, in a conventional lid opening device having lid opening functions for different applications at both ends of a single output shaft, when one of the functions is set to develop a proper capacity, the other develops an excessive or a sufficient capacity. [MEANS FOR SOLVING PROBLEMS]  This lid opening device comprises a shift part (50) having a gear train for matching the output of a motor to the purposes of a plurality of output shafts and an output selector part for the gear train. Since the shift part transmits optimum torques to the output shafts (133) and (140) and can selectively drive only one output shaft via. the output selector part, safety can be increased.  Also, an installation space and a storage space can be saved by adopting a ceiling-hanged type device.
