  • Publication number: 20240316700
    Abstract: Systems and methods are provided for utilizing wearable wire feeders. An example welding-type system may include a wire feeder device configured for operation in conjunction with a welding-type power supply unit and a welding-type torch, with the wire feeder device being a physically separate component from both of the welding-type power supply unit and the welding-type torch, and with the wire feeder device including, at least, a wire source configured to provide electrode wire, and a wire feeding mechanism configured to feed the electrode wire from the wire source. The wire feeder device may be powered by the welding-type power supply unit, and the wire feeder device may be configured to feed the electrode wire to the welding-type torch.

  • Publication number: 20240316675
    Abstract: Systems and methods are provided for utilizing in-line wire feeders. A welding-type system may include an in-line wire feeder device configured to feed electrode wire from a wire source. The in-line wire feeder device may include an in-line wire feeding mechanism, may be a physically separate component from both of a second wire feeder device and a welding-type torch, and may be connected in series with the second wire feeder device. The in-line wire feeder device may control feeding of the electrode wire from a wire source, with the controlling including causing the second wire feeder device to feed the electrode wire from the wire source until the electrode wire reaches the in-line wire feeding mechanism, and then afterwards deactivating at least a feeding function of the second wire feeder device, and causing the in-line wire feeding mechanism to take over feeding of the electrode wire from the wire source.

  • Publication number: 20170006986
    Abstract: A card holder and illuminated display device with a lower portion and an upper portion, where the lower includes a card holding space and a power source. The upper portion configured to cover the card holding space in the closed position and allow access to the card holding space in the open position. The upper portion also including a signaling panel, while the device includes a light source positioned so that in the open position the signaling panel of the upper portion may be edge illuminated. The panel may incorporate a design that is highlighted when the light source is turned on.

  • Publication number: 20060090258
    Abstract: A patient transfer device includes a base assembly movable in forward and lateral directions. A power train is mounted within the base assembly, and is connected to a clamping and strap assembly. A power and switching system is in electrical communication with the power train. A retractor bar carries one or more clamping devices that are releasably attachable to a sheet. The clamping devices include a clamp handle pivotally connected to a clamp base and a clamp arm eccentrically pivotally connected to the clamp handle. The clamping and strap assembly is supported on the base assembly by a vertical adjustment assembly that includes a positioning mechanism for releasably locking the clamping and strap assembly at one of a plurality of vertical positions. An attendant can stand on the base assembly to act as a counterbalance to a patient's weight.
