  • Patent number: 6421563
    Abstract: A solid-state defibrillation circuit for applying a multiphasic defibrillation pulse to a patient is disclosed. The circuit eliminates the need for a mechanical relay, and provides for a current limiting circuit for limiting leakage currents that would otherwise flow to the patient from the solid-state components, and for preventing the short-circuiting of a defibrillation pulse from a second defibrillator. In one embodiment, the output circuit of the defibrillator comprises an H-bridge, and the current limiting circuit comprises a plurality of resistors coupled in parallel with each of the legs of the H-bridge. The plurality of resistors allow current flow which reduces the voltage potential across the patient that is caused by the leakage currents through the output circuit. The current limiting circuit also includes a shunt resistor for shunting leakage currents away from the patient.

    Abstract: A method is provided for using a pad printing device to decorate a base surface with an image. Initially the form of the image is printed on the base surface using a base coat material which has a sufficiently high adhesion with the base surface. An ink image is then printed in registry with the base coat image using an ink which has a sufficiently high adhesion to the base coat material. The image is then printed in registry with the ink image using a top coat material which has a sufficiently high adhesion to the ink. Because each layer of material has a sufficiently high adhesion to the adjacent material, the resulting decorative label has a high adhesion to the base surface.

    Abstract: At least one layer of a conductive organic polymer, formed by electropolymerization on the anode in a two electrode cell, is bonded to a plastic substrate by compression with sufficient heat and pressure to cause it to bond to the substrate and release from the anode. Improved sandwich-type capacitive electronic discs having an information pattern in ultra thin outer conductive layers which are homogeneous and which contain no conductive particles are formed by this process by providing as the anode a mastering disc containing an information pattern which is the negative of the desired information pattern.

  • Patent number: 4515739
    Abstract: A matrix coating system and method of manufacture thereof is presented wherein the matrix coating contains chemical blowing agents which permit low pressure molding and also the formation of printing plates having deep relief. The method of manufacture is such that a foamed coating is produced which at molding temperatures is highly compressible at low pressures and which also expands into the relief or nonprinting regions of the pattern plate. The unusually low molding pressures necessary result in less distortion of rubber pattern plates or made from photo polymers. In addition, the combination of high compressibility in appropriate areas, and of volume expansion in relief areas allows the board coating to conform before and during cure to pattern plates of deep relief, so that in the cured state there results a rigid, durable high fidelity mold useful for molding numerous flexographic printing plates.

  • Patent number: 4474842
    Abstract: An improved, waterproofed, non-slip, non-skid kraft lumber wrap for covering milled lumber as stacked for shipment on flatbed railroad cars and having a printed application of a high friction material which is applied in the form of a plurality of groups of generally quarter-circular area shapes, the shapes in each group being spaced apart in transverse directions to form a unitary pattern of predetermined total area size which, when repeated on predetermined centers over the central upper side area of the wrap will, when in use, provide an overall non-skid surface for the top surface of the wrap covered lumber stack where workmen are likely to walk during loading and unloading operations, the circular area shapes of each pattern being so arranged that in the overall application of the pattern onto the lumber wrap, the area of an average sized worker's foot, as he walks on the covered lumber stack, will always be in contact with a portion of at least two of the circular shapes comprising the overall applicati

  • Patent number: 4452843
    Abstract: Security papers with luminescing authenticity characteristics built in or printed thereon which absorb in the visible region of the optical spectrum but in the infrared have a transparent region in which the luminophore also emits. By the absorption in the visible undesired parasitic emissions are suppressed which would make the luminophore visually evident on corresponding excitation. For testing the authenticity of the document the emission is investigated in the infrared. Suitable luminophores are rare earth metal luminophores in suitable host lattices, particularly in ferrite lattices or garnet lattices, which contain transition metal ions as absorbing elements.

  • Patent number: 4451530
    Abstract: Security papers with luminescing authenticity features worked into them or printed on them. The authenticity features used consist of a luminophore and one or more absorbing materials by which the emission and/or the excitation spectrum of the luminophore is changed in detectable fashion. The dyestuff can be present as an admixture to the luminophore, as a coating of a luminophore layer or as a coating on luminophore powder grains. For checking the authenticity of documents the emission spectrum of the luminophore is not used but the change generated by the technology used in the emission or excitation spectra.

  • Patent number: 4451521
    Abstract: Security paper with luminescing authenticity characteristics which after excitation with invisible light emit exclusively invisible light of different wavelengths as authenticity signal. The luminophores can be included in the printing ink used or they can be added to the paper material in the manufacture of the paper material. A corresponding test apparatus makes it possible to check the authenticity of the security paper in the presence of customers but unnoticed by them; thereby the invisibility of the test signal and the authenticity signal are taken advantage of and the test device is hidden behind a plate non-transmissive for visible light which however is transmissive for the test signal and for the authenticity signal.

  • Patent number: 4442170
    Abstract: Security paper with narrow band luminescing authenticity characteristics which can only be excited in substantially the same wavelength region in which it also emits. With these authenticity characteristics therefore the authenticity signal is overlapped or covered by the test signal of several orders of magnitude stronger. The authenticity of the security papers cannot accordingly be tested with the normal processes or devices for determining of luminescence. The test devices used take advantage of the decay behavior of the luminescence emission for detection. The authenticity characteristics can be added to the paper material, the printing ink used, further mottling fibres or security threads.
