  • Publication number: 20090133809
    Abstract: When building an unvulcanised tyre from tyre components using a tyre building drum, the mutual distances considered in axial direction between a bead ring segment, a first end and a steering element of a folding arm in question are chosen such that at movement of a steering element towards the bead ring segment a steering surface comes to abut the steering element so that the roller element can be moved from a first position, after which the roller element presses an outer part of the tyre components against a bead ring core to be placed on the bead ring segment while simultaneously the roller element moves away from the longitudinal axis, wherein the steering element moves along the steering surface until the stop of the annular steering segment abuts an annular folding arm segment, after which the folding arm swivels about a swivel axle and the steering element comes to lie apart from the steering surface.

  • Publication number: 20040024455
    Abstract: A prosthesis for placement in the area of the pharynx, an upper region of the trachea or in a wall between the esophagus and an upper region of the trachea is provided with an air passage and a vibrating element for vibrating air. Because the prosthesis is provided with a stop for abruptly impeding the movability of the vibrating element in at least one position, sound with a broad spectrum of frequencies is produced which, when speaking, can be effectively converted into the desired sounds. This ensures a highly improved understandability and a more natural voice. According to a practical possibility, the voice prosthesis is incorporated in a one-way valve as a modular part.

  • Patent number: 6274988
    Abstract: An apparatus for starting and operating UV lamps, comprises an AC line powered circuit and a UV lamp. The circuit has a variable frequency AC source, providing AC current to the UV lamp and a ballasting inductor, connected in series with the UV lamp. The inductor and the lamp form a nonresonant coupling sub-circuit where a flow of current from the AC source through the UV lamp is limited by the ballasting inductor. The circuit does not develop dangerously high output voltages if the UV lamp is disconnected or burnt out, as would be the case with resonant output circuits, unless additional circuit protection was implemented. The impedance of the ballast inductor varies with the current frequency, enabling it to act as a current control element with changes in the output frequency. An open loop control circuit of the present invention maintains the lamp current at a relatively constant level without the complexity imposed by closed loop current control methods.

  • Patent number: 4928585
    Abstract: Method for controlling the passage of the fabric through a rotary screen printing installation, whereby a substrate or fabric to be printed is wound from a stock roll and fed into the printing machine of the installation. In order to reduce down times and the waste of mostly expensive substrate the printing machine is set using a fabric of low quality, the so-called leader. The substrate to be printed is sewn to the trailing end of the leader so as to print the substrate after the printing machine is set for first quality printing. The length of substrate is measured and compared with the total length of the print order by means of an electronical processing unit.
