摘要： A signal sampling circuit receives a clock signal indicative of a sampling rate and a periodic input signal to produce a digitized sampled output signal. The sampled signal is applied to an all-pass filter having a single pole/zero pair in which the pole/zero values are determined by a number supplied by a number generator. The number generator varies the applied number in a random or pseudorandom fashion to create a correspondingly random or pseudorandom variation of the transfer function of the filter. The filtered sample signal is then further processed by an absolute value operator and an average value operator for application to an amplitude responsive device such as a meter. The random or pseudorandom variation of the filter transfer function introduces a corresponding random or pseudorandom variation of the phase shift imposed upon the sampled signal within the filter. This. phase shift operates to impede or preclude the generation of erroneous beat note amplitude variations within the sampled signal for input signals having frequencies at or near the sampling rate or submultiples thereof.

摘要： A composition and method for forming investment casting shells includes using colloidal silica, zircon flour, and fused silica in a slurry which is applied to a pattern. After the slurry is applied to the pattern, it is allowed to partially or completely solidify. After the shell has solidified, the pattern may be melted or otherwise removed. A molten material is introduced into the shell and allowed to cool to form an article. Finally, the shell is broken away or otherwise removed from the article. The improved shell slurry composition and corresponding method minimizes pattern-to-pour cycle times and is environmentally friendly.

摘要： The invention includes a method of mounting a component to the skin of an aircraft. The component can include a drain valve, a gas cap, other external fuel instrumentation such as sensors, and antennae. One aspect of the invention includes a new method of mounting a drain valve to an aircraft fuel tank. The drain valve in the method includes any conventional drain valve having a stem and a flange that surrounds the stem. The method includes applying a material around a drain opening of the fuel tank; the material directs an electric charge away from the drain valve.
