  • Publication number: 20030115924
    Abstract: A wire drawing machine is provided with a pressure roller in the form of a roller sized to extend substantially across the width of the capstan and engage multiple turns of wire thereon in a lower quadrant on the exit side of the capstan. The pressure roller is mounted for pivoting about a horizontal axis parallel to the axis of the capstan, and for automatic angular positioning and alignment as contact is made with the wraps of wire on the capstan.
    Type: Application

  • Patent number: 5174719
    Abstract: Drag produced by cold, viscous oil, interacting with the gear meshes of a gear drive (8) connected to a ram air turbine (2) of an aircraft (1), is controlled to allow proper start-up of the ram air turbine. The lubricating oil is isolated from the gear meshes in remote sumps (11, 12) when the turbine is located in the stowed, inoperative position. An oil metering orifice controls the oil flow from the remote sumps to gearbox sumps with movement of the turbine from the stowed position (A) to the deployed position (B), so as to delay the application of cold, viscous coil to the gear meshes until after start-up of the turbine. This avoids excessive start times and failure to start from the high drag caused by cold, viscous oil on the gear meshes.
