  • Device for tilting and turning coke-oven doors for maintenance purposes
    Patent number: 4620828
    Abstract: The invention relates to a device for tilting and turning coke-oven doors for the purpose of maintenance and repair. It comprises a door-receiving support frame with upper guide rollers, which are guided in a guide rig having parallel rail pairs. At the lower end of the support frame a firmly connected drive device engages, which is movable on a raised horizontal rail track. The drive device pulls the support frame from the vertical into the horizontal position and pushes it back into the vertical position. The guide rig includes a vertical part and an inwardly extending part contiguous thereto. The center between the guide rig on the coke side and the guide rig on the machine side is interrupted. The rail pairs end at the bottom in sturdy stops for the guide roller. The invention is thus an accident proof tilting device, with sufficient space for repair purposes being available on the working platform.

  • Multi-purpose pet maintenance device
    Patent number: 10905104
    Abstract: A pet maintenance device for use by a user with a pet animal can be selectively moved to multiple positions for use for multiple purposes or applications. The pet maintenance device includes a device body that is selectively movable among a closed position, a partially open position, and a fully open position. The device body includes an outer body member and a foldable flap member that is connected to the outer body member. When the device body is in the closed position, the device body is substantially flat. When the device body is in the partially open position, the device body is configured to allow the user to grasp the foldable flap member to pick up pet waste. When the device body is in the fully open position, the device body is configured to be substantially bowl-shaped to be usable as a bowl for holding a consumable.

  • Local maintenance controller for gas turbine power plants having a primary control system
    Patent number: 3975902
    Abstract: A local maintenance controller permits continued power generation during maintenance or failure of a primary gas turbine control system by manually for maintenance purposes or automatically for failure purposes assuming turbine control to thereby insure continued operation. The local maintenance controller set forth is particularly suitable for use in conjunction with a computer implemented gas turbine control system.Transfer between the local maintenance controller and the primary control system is effected in a bumpless manner so that load swings are absent. However, if the turbine was operating at system reserve at the time of transfer, the local maintenance controller reduces the load to peak value until primary control is resumed. Operation at any other load at the time of transfer is maintained by the controller. Transfer back to primary control is also effected in a bumpless manner.

  • Method for lifting a generator rotor shaft to facilitate shaft breakaway and maintenance
    Patent number: 5331243
    Abstract: The method of lifting a generator rotor shaft (12) off its bearing (10) to enable breakaway during start-up and for maintenance purposes includes providing a hydraulic cylinder (22) with a pair of rollers (28) mounted on the cylinder piston (32) engageable with the shaft (12). At start-up, the cylinder is actuated to elevate the shaft a maximum distance of about 0.005 inches to enable a film of lubricating oil to flow between the shaft journal and the bearing pads. For maintenance purposes, and after removal of the upper bearings, the shaft can be elevated by actuation of the jack a distance sufficient to enable removal of the lower bearings from the pedestal.

  • System and method for diagnosing aircraft components for maintenance purposes
    Publication number: 20030083794
    Abstract: Aircraft maintenance and repair work is facilitated, especially for a commercial aircraft, by a diagnostic system and method, wherein an aircraft component or assembly of components is monitored by at least one sensor which produces and preferably also stores component status information. Respective status information signals are transmitted, preferably in a wireless manner, from a transmitter of the sensor to a receiver of a signal processing unit which provides status information on a display screen. The status information signals are preferably processed and evaluated with reference to rated maintenance and repair reference information to provide instructions as to what needs to be done where and when for a maintenance or repair. The sensor or sensors may operate during flight and the respective stored information is then processed and used on the ground.
