  • Patent number: 11565342
    Abstract: A linear friction welding system includes a processing circuit configured to execute program instructions stored in a memory to control a first motor using one of a torque and speed control, placing a plurality of timing gears in a configuration wherein a fixed projection of one of the timing gears is at a trail position of a slot of another timing gear such that two power shafts of a cam assembly are rotating in phase and a ram is motionless. The processing circuit further controls a hydraulic press to generate a pressure between two components to be welded with the power shafts rotating in phase, and controls the second motor using the one of the torque and speed control to place the timing gears in a second configuration whereat the fixed projection is at a lead position of the slot thereby forcing the ram to oscillate.

  • Patent number: 11565353
    Abstract: The axle welder can be easily configured and adjusted to accommodate axle assemblies of varying axle shaft lengths, hub styles (“straight” and “drop axle”) and lug bolt configurations. The axle welder uses a sliding carriage that slides along the support frame at one end of the welder to accommodate differing shaft lengths. The axle welder also includes a pair of pivoting hub lifts that accommodate both straight and drop axle style axle hubs using modular mounting plates. Modular mounting plates (“hub adaptors”) fitted to the hub lifts accommodate hub assemblies with differing lug bolt patterns. The axle welder is built on a rectangular frame that supports a pair of weld units and articulated electrode arms. The axle welder also includes a pair axle supports for carrying the axle shafts within the support frame. A shaft drive pivotally mounted to the support frame lowers to engage and rotate the axle shaft and hub assemblies in unison during the welding process.

  • Patent number: 11335551
    Abstract: The present method comprises providing a flexible web substrate (e.g., polymeric flexible web substrates) that forms at least part of a component of a device, coating so as to wet-out on and cover all or a substantial portion of a major surface on one side or both sides of the flexible web substrate with flowable polymeric material, while the flexible web substrate is moving in a down-web direction, and solidifying the polymeric material so as to form one cleaning layer on the major surface of one side or both sides of the flexible web substrate. The present invention can be utilized in a continuous in-line manufacturing process. In applications of the present invention where the flexible web substrate will not form a component of a device, the present invention broadly provides a method for cleaning particles from a flexible web of indefinite length.
