Abstract: A method and apparatus for restoring airseals on gas turbine blades and vanes. A worn or damaged airseal is removed by abrasive belt grinding perpendicular to its length to create a stub. Then a piece of material is joined to the stub, as by welding. Next the airseal weldment is contoured using abrasive belting, perpendicular to the weldment length.The invention is particularly advantageous for the repair of components having two airseals of different dimensions. A single two-position fixture is usable to remove old airseals and to refinish airseal weldments. Refinishing is accomplished with a contoured belt; the contour is chosen to be intermediate, but within the tolerance of, the contours of the first and second airseals. As a result, airseals are economically restored in short runs.

Abstract: The tool is useful for the replacement of the lateral control torque tube bearings on high performance aircraft. The bearings are pulled into position into the bulkhead in a straight line thereby preventing them from becoming jammed because of the angle of the bulkhead surface into which the bearings are to be installed. The tool self-aligns the bearings without putting pressure on the bearing race thereby preventing the possibility of damage to the bearing and since the use of a shoulder driver and hammer are no longer required, damage to the bearing and/or aircraft is virtually eliminated.

Abstract: There is disclosed a technique for tightening threaded fasteners in which values of offset torque, initial tension rate relative to angle, final tension rate relative to angle and other joint related factors are empirically determined by instrumenting a plurality of fasteners of the type ultimately to be tightened. In one embodiment, torque and angle are monitored during tightening. Calculations are conducted, while tightening, to determine the tension prevailing in the bolt at a particular angle of advance. By using the calculated tension value and the particular angle of advance, an instantaneous position of threading advance on the tension-angle curve of the fastener is established. From this instantaneous position, it is determined how much greater angle of advance or how much torque is required to tighten the fasteners to a final desired tension value. The same technique may also be used merely to monitor tightening which is terminated by a different tightening strategy.

Abstract: The applicator includes a plastic disc having a central hole therein. Integral with the disc and extending from the upper side thereof is a tubular handle, the bore of the handle being in alignment or registry with the hole in the plastic disc. By means of the handle the disc can be rotatively oscillated against the uppermost paper filter of a stack of such filters so as to induce electrostatic charges thereon with the consequence that the filter clings to the lower side of the disc. The disc is slightly smaller in diameter than the diameter of the paper filters to be transferred, and the peripheral diameter of the paper filters is slightly greater than the diameter of the coffee maker basket. In this way, when the plastic disc and the filter being electrostatically carried thereby is inserted into the coffee maker basket, the peripheral edge of the filter is deflected upwardly, the frictional engagement causing the filter to remain in the basket when the plastic disc is retracted.

Abstract: This application covers a device included in the microprocessor control for winders or sheeters; the device is arranged to stop the machine when a desired length of web has been fed by accurately-timed start of deceleration from full speed. This avoids the need to run at a lower speed for a period as the desired length is approached.In the device, the web speed is sensed by a transducer which delivers a speed signal, and from this is calculated the length of web which will be fed during standard deceleration. The result of this calculation can then be compared with the difference between desired length and length already fed (or the result plus length already fed can be compared with desired length) and when the result of this comparison indicates deceleration should start a signal is sent to the braking system.As an alternative to calculation of length of web fed during deceleration from the sensed speed, the result may be obtained by a "table look-up" operation.
