  • Patent number: 6835299
    Abstract: An electrochemical machining technique involves moving a cathode (2) towards an anodic workpiece (1). A current is passed through an electrolyte which flows between the cathode (2) and workpiece (1) so as to cause material to be removed electrolytically from the workpiece (1). A vibratory movement is imposed on the cathode (2) and the current passed between the cathode (2) and workpiece (1) is also varied. The vibratory movement may consist of a main sinusoidal oscillation and a secondary ultrasonic vibration, and the current variation is synchronized with the main vibration so that current pulses, and ultrasonic vibration pulses, coincide, with a predetermined small phase shift, with peaks of the main vibration corresponding to the smallest gap between the cathode (2) and workpiece (1).

  • Patent number: 6574945
    Abstract: A number of spaced apart first and second cavities are continuously formed in first and second thin sheets of material, respectively. Each of the first and second cavities has an edge at an opening thereof. The formed first and second cavities travel in paths that are downwardly inclined from the horizontal and approach each other. A number of first bodies are fed into the first cavities, respectively, where each of the first bodies has a liquid tight interior cavity that contains a volume of a first liquid. This liquid is one that when mixed with a second liquid starts a chemiluminescent reaction. The edge of each of the first cavities is sealed progressively with the respective edge of a second cavity, while injecting the second liquid into one or both of the first and second cavities that are being sealed. This forms a liquid tight second body that contains the first body and a second volume of the second liquid.

  • Patent number: 6557571
    Abstract: A crutch constructed of two adjacently located, elongated, parallel upper and lower bows which can be moved in relationship to each other to form a vertical support of readily varied length. These bows have the same design and are therefore interchangeable, significantly reducing inventory requirements. Each bow has a series of parallel horizontal notches with the bows positioned so that the notches on each bow are on contacting surfaces. A pin inserted into parallel, adjacent notches on the two bows in cooperation with two or more collars or caps on the ends of one end of each bow fixes the relationship between the shafts which, in turn, defines the length of the vertical support. A similar concept can be used to lock a moveable centrally located lower bow between two parallel outer upper bows. This assemble provides a strong, adjustable length crutch for any height patient using only two different pairs of bow lengths.
