  • Patent number: 8844250
    Abstract: A sealing device for producing sealed packages from a tube of packaging material fed along a path and filled with a pourable food product, comprising: a frame; a pair of jaws movable cyclically with respect to the frame and along part of the path to grip the tube; ultrasonic sealing means carried by a first jaw to seal the tube; and power means including a primary winding fixed to the frame and connectable to an electric energy source, and a secondary winding carried by the first jaw, supplying the sealing means, and receiving electric energy by electromagnetic induction from the primary winding as the first jaw travels past the primary winding; and the device having transformer means supplied by the electric energy source with a first voltage value, and supplying the primary winding with a second voltage value lower than the first voltage value.

  • Publication number: 20040156852
    Abstract: Methods for treating cells, diseased tissue, pathogens, or other undesirable matter involve the administration of a bioprobe (energy susceptive materials that are attached to a target-specific ligand) to a patient's body, body part, tissue, or body fluid (such as blood, blood plasma, or blood serum). An energy source provides energy to the bioprobe so as to destroy, rupture, or inactivate the target. Various energy forms, such as AMF, microwave, acoustic, or a combination thereof, created via a variety of mechanisms, may be used. The disclosed methods may be useful in the treatment of a variety of indications, including but not limited to, cancer of any type, such as bone marrow, lung, vascular, neuro, colon, ovarian, breast and prostate cancer, AIDS, adverse angiogenesis, restenosis, amyloidosis, tuberculosis, obesity, malaria, and illnesses due to viruses, such as HIV.

  • Patent number: 6162509
    Abstract: A self-fusing alloy thermal spray coating or a vitreous ceramic coating is fused to a complicated metal shape or convoluted metal surface, such as a waterwall panel having a plurality of tubes interconnected by a plurality of membranes, without significant warpage or adverse change in the microstructure of the material forming the panel. The coating is first applied to the panel and then is heated to a liquidus temperature (typically between about 1000.degree.-2200.degree. F.), by induction at a frequency of greater than about 25 kHz, so as to effect fusing. An inductive coil assembly for this purpose comprises a copper tubular combined electrical current conductor and conduit for circulating cooling water having a first closed end and a second end connectable to a source of cooling fluid and a source of electricity. At least one, and preferably a plurality, of copper noses extend outwardly from the combined conductor and conduit and both conduct electricity and circulate cooling fluid.
