Static Charger Or Discharger Patents (Class 242/906)
  • Patent number: 9022270
    Abstract: A flexible and continuous substrates-conveying sheet has a plurality of to be processed substrates disposed on or in it. A nondestructive transferring unit includes a plurality of first transferring rolls and a plurality of second transferring rolls. The first transferring rolls make contact with a first surface of the substrates-conveying sheet where that surface can have electrostatically-induced charge formed thereon. Each of the first transferring rolls includes a first central portion charged with a positive electric charge and a first outer portion surrounding the first central portion. The second transferring rolls make contact with the first surface of the substrates-conveying sheet. The second transferring rolls are disposed alternately with the first transferring rolls. Each of the second transferring rolls includes a second central portion charged with a negative electric charge and a second outer portion surrounding the second central portion.

  • Patent number: 7387274
    Abstract: A method of grounding a dispenser. A low impedance path is connected to elements internal to the dispenser. The low impedance path is also connected to a surface contact spring which is adapted to contact an external mounting surface when the dispenser is affixed thereto. Static electrical charge accumulated on the elements is discharged through the low impedance path and the surface contact spring to the external mounting surface.

  • Patent number: 7216828
    Abstract: In order to be able to adjust the tension and position of a material web, for example, a paper web, that should be printed by a printer, an electrostatically-acting braking device is described that provides a charger, for example, a corotron, and a braking plate, between which the material web runs. The charger charges the material web, which is thereby drawn to the braking plate, lies on the braking plate, and is braked via friction. It is advantageous that the charge voltage of the charger and be controlled via sensors for the web tension and web position and can very quickly react to the signals of the sensors.

  • Patent number: 7182289
    Abstract: Apparatus for dispensing paper from rolls which feeds continuously, roll to roll, and does not require extra procedure to bring stub roll into position. The apparatus holds and positions at least first and second rolls of paper with respect to each other, dispensing paper from the first and second rolls simultaneously when the first roll reduces to a predetermined diameter of paper, positioning the depleted first roll for replacement without the necessity of removing the second roll; and dispensing from the second and replacement rolls simultaneously when the second roll reduces to a predetermined diameter of paper. The apparatus also has a proximity sensor, which senses when a hand is placed near the dispenser, and thereupon dispenses a set amount of towel. The dispenser dissipates static charges to a local ground such as a high impedance wall surface on which the dispenser is mounted.

  • Patent number: 6497267
    Abstract: A motorized shade control system is described in which electrostatic charges, generated by a shade fabric being reeled on to and off of a roller are conducted to and grounded by the shaft of a remote drive motor. The drive motor is ultraquiet, and includes a worm gear drive and single-stage reduction gear assembly which delivers about 0.010 to 0.005 horsepower, with motor output shaft rotational velocity limited to no more than about 30RPM. The motor is mounted within a two-part housing and is clamped between elastomeric acoustic dampers connected between pedestals extending from opposite interior wall surfaces to opposite sides of the motor. An H-bridge drive circuit powers the motor under the control of a microprocessor which can be addressed by an infrared remote transmitter or by a wall mount control. Soft start and soft stop circuits are employed to further reduce noise.

  • Patent number: 6308908
    Abstract: The machine is equipped with a device for cutting the sheet to shift from one roll to another; the cutting device comprises a stand (3) on which a turret (2) has been mounted, said turret bearing at least two parallel spindles (1), each linked to rotating driving means known in the art; the rotation of the turret simultaneously removes a full roll and brings an empty spindle to the coiling station. A carriage (5) capable of motion perpendicular to the spindle axis conveys cylinders to load the machine with sheets to be rolled.

  • Patent number: 6027778
    Abstract: The present invention provides a novel one-piece capstan for a tape cartridge which provides good static dissipative properties and wear resistance. The capstan material of the present invention has a charge decay time of no more than 5 seconds as measured according to Mil B-81705C standard. The capstan material also has a flexural modulus of at least 200,000 psi (1379 MPa). The capstan comprises a hard, dimensionally stable polymer and a static dissipating polymer. The capstan also has an improved structure and geometry which enables the part to be easily molded, reduces drive force requirements with a reduction of material from the prior art design, but with no significant loss of performance properties.

  • Patent number: 5839685
    Abstract: The thread feeding wheel is capable of preventing static-electricity from being produced due to rapid feeding of the thread and which provides a surface having a low frictional coefficient so that the thread feeding around the thread feeding wheel would subject to minimal frictional damage. The cylindrical body is made of an aluminum alloy. A layer of oxide of the aluminum alloy is formed by a hard anodizing process on the middle portion of said cylindrical body. A layer of polytetrafluoroethylene resin is impregnated over said oxide layer to further reduce the frictional coefficient of the thread running surface.
