| 20090196742 | RETRACTABLE COMPLIANT PLATE SEALS - A seal arrangement for sealing the space between a rotating element and a stationary element, the sealing arrangement comprising a compliant plate seal housing supported adjustably in the stationary element, the compliant plate seal housing supporting a compliant plate seal; and a spring system provided between the compliant plate seal housing and the stationary element to bias the compliant plate seal housing in a direction away from a surface of the rotating element. Alternatively, or additionally, one or more actuators may be provided to move the compliant plate seal housing in a direction away from a surface of the rotating element. | 08-06-2009 |

| 20090309311 | Methods and apparatus to facilitate sealing in rotary machines - A method and seal assembly for a rotary machine including a rotary component and a stationary component is provided. The method includes providing a seal housing including a front plate and a back plate that is spaced from the front plate such that a cavity is defined between the front plate and the back plate. The method also includes coupling a plurality of flexible compliant plates to at least one of the seal housing and the stationary component such that the compliant plates are spaced from the front plate and the back plate within the cavity, and coupling at least one projection to at least one of the seal housing and the compliant plates such that the at least one projection facilitates reducing flow through at least one of a first axial gap and a second axial gap that are defined between the seal housing and the compliant plates. | 12-17-2009 |
| 20100213675 | Method Of Manufacture Of Compliant Plate Seals - A compliant plate seal arrangement manufacturing method is provided. A compliant plate seal manufacturing method includes assembling a plurality of t-shims and a plurality of spacer shims into a straight weld fixture, thereby forming a shim pack having a front and rear end and sides, welding the sides of the shim pack to a top plate, removing a portion of the weld fixture, removing the plurality of spacer shims, shaping the shim pack into a target diameter, and applying a radial flow plate to the leaf pack. | 08-26-2010 |

| 20090177329 | Hydraulic Control Scheme for Surface Maintenance Machine - A control system and method of use for controlling work output delivered to a floor surface by a work tool associated with a floor maintenance machine. The control system includes a hydraulic power source, a motor assembly coupled to the power source and the work tool, a pressure sensor in communication with the motor assembly, an actuator coupled to the work tool, and a controller in communication with the pressure sensor. A valve is configured to regulate the pressure provided by the power source and applied the actuator assembly. Based on a sensed pressure applied to the motor assembly, the controller causes the actuator assembly to adjust contact of the work tool with the floor surface. Work output delivered to the floor surface by the machine can be uniformly maintained during a cleaning period as the controller adjusts floor contact of the work tool via the hydraulic actuator. | 07-09-2009 |
| 20110107540 | Quick Lock Squeegee Attachment and Method of Use - A releasable squeegee assembly for coupling to a surface maintenance machine and including a compliant bushing and an over-center lever attached to a pull rod and compliant spring. The compliant bushing is compressed via said over-center lever with said compliant spring providing a spring force. A bushing sleeve is provided to limit the degree of compression of said compliant bushing by the over-center lever. A method of coupling a squeegee assembly to a surface maintenance machine is also provided. | 05-12-2011 |
