  • Patent number: 10391325
    Abstract: A subcutaneous implantable cardioverter-defibrillator (S-ICD) comprising shocking electrodes configured to reduce the defibrillation threshold. The S-ICD may include a canister housing a source of electrical energy, a capacitor, and operational circuitry that senses heart rhythms and an electrode and lead assembly. The electrode and lead assembly may comprise a lead, at least one sensing electrode, and at least one shocking electrode. The at least one shocking electrode may extend over a length in the range of 50 to 110 millimeters and a width in the range of 1 to 40 millimeters.

  • Patent number: 7879209
    Abstract: A magnetron sputtering cathode for use in a vacuum deposition process is disclosed wherein the cathode is coated on its sides with an electrically insulating material such as alumina to prevent arcing, and wherein the first end surface of the cathode supports a material to be sputtered. The bottom of the cathode may also be coated with an electrically insulating coating or may be resting upon an insulating platform.

  • Publication number: 20090250341
    Abstract: A sputtering anode is disclosed wherein the anode is in the form of a container or vessel; and, wherein the conducting surface communicating with a cathode is the inside surface of the container or vessel. The anode can be mounted outside of a coating chamber having its opening communicating with the chamber or alternatively may be mounted within the chamber. The anode may be an inlet port for receiving inert gas for use in forming the plasma and for pressurizing the anode.

  • Patent number: 4536998
    Abstract: Flexible selective energy control sheet construction formed of a sheet of substantially transparent polymer thin film plastic material having first and second surfaces. A substantially transparent continuous adhesion promoting layer is adherent to the second surface of the sheet. A substantially transparent metal layer is adherent to the adhesion promoting layer and a protective layer is adherent to the metal layer. The metal layer is selected from the materials of copper and silver.

  • Patent number: 4422721
    Abstract: Optical article having a substrate with first and second surfaces and with a conductive antireflection coating disposed on the first surface. The conductive antireflection coating is comprised of at least one layer of a low index material carried by said first surface and a thin transparent conducting layer of a material having a high index of refraction carried by the layer of material having a low index of refraction. The conducting layer provides an exposed surface to which the direct electrical contact can be made. The conducting layer has an optical thickness ranging from 1.0 to 30.0 nanometers. The layer of material having a low index of refraction has its design thickness reduced to compensate for the thickness of the conducting layer whereby the conducting layer does not seriously degrade the optical performance of the coating over that which could be obtained without the use of the conducting layer.

  • Patent number: 4108596
    Abstract: A process and a product formed thereby for the recovery of chromium values from aqueous solutions (e.g., waste liquors) comprises contacting an acidic solution containing sulfate ion and trivalent chromium ion with at least about 4 molar equivalents of MgO or Mg(OH).sub.2 per 3 molar equivalents of trivalent chromium in addition to the amount required to neutralize the free acid to a pH of about 4 to form an amorphous, dense solid, grainy, easily settleable, trivalent chromium-containing precipitate in an alkaline solution according to the equation: 3Cr.sub.2 (SO.sub.4) + 8 MgO .fwdarw.Cr.sub.2 (OH).sub.4 SO.sub.4 .multidot. 4Cr(OH).sub.3 .multidot. 4H.sub.2 O + 8 MgSO.sub.4. The trivalent chromium-containing product can be readily separated from the water and is a useful source of chromium for subsequent processing. The water remaining after separation of the precipitate contains less than 0.5 mg/l chromium.
