  • Patent number: 4799130
    Abstract: A dielectric strength tester is disclosed for use with high-voltage, high-volt amperage electrical equipment. The step-up transformer has a high-voltage secondary winding which is connected through first and second primary windings of a sensing transformer to first and second test terminals. If an operator should contact the second test terminal, which is at high voltage, this would cause a fault-to-ground current, which is an imbalance on the two primary windings, and hence supply an output on the secondary winding of the sensing transformer. This voltage is rectified and passed through a set point resistor means to trigger a thyristor into conduction. This thyristor is connected to de-energize a triac in series with the primary of the step-up transformer. The sensing is rapid because it is carried out in the high voltage secondary, yet the control is in the lower voltage primary of the step-up transformer.

  • Patent number: 4281362
    Abstract: This invention deals with an improved electrostatic shield which is adapted to be mounted on the applicator of a conventional diathermy apparatus between the radiating electrode thereof and the patient receiving treatment. The shield is comprised of a first and a second plurality of electrically conductive strips which form the body portion of the shield and which encircle the current carrying coil of the radiating electrode. The strips likewise form the face portion of the shield and define a plane which is generally parallel to the plane formed by the current carrying coil.Each strip of the face portion is preferably coupled with one of the strips of the body portion. However, the face portion strips of the shield extend generally radially inward from the outer periphery of the surface defined by the face of the shield. These strips then terminate within the inner portion of the area defined by the shield such that the terminating end of the strips are electrically insulated from each other.

  • Patent number: 4068292
    Abstract: Method and apparatus for minimizing or preventing the deleterious skin heating effects associated with conventional short wave diathermy treatment. The disclosed method includes attenuation of the electrostatic field transmitted by the applicator head and transcutaneous transmission of the radiated electromagnetic energy substantially unimpeded to the deep body tissues to be treated. The attenuation of the electrostatic field is performed by an electrostatic shield, which is adapted to be positioned on the diathermy applicator head between the radiating electrode and the patient receiving treatment. However, the radiated electromagnetic field, which is primarily responsible for the therapeutic generation of heat in relatively deep body tissues, passes through the shield substantially unimpeded. The shield comprises a plurality of narrow, preferably metallic, spaced apart strips and an electrically conductive loop which surrounds the strips and is coplanar therewith.
