Abstract: A lubrication system includes an inlet conduit having an inboard end attached to a bearing support and an outboard end for receiving lubricant. A lubricant inlet assembly is attached to the inlet conduit outboard end and has an inlet cap with a receptacle, an inlet cap body, and a cap base. The inlet receptacle is configured to mate with a lubricant supply line, where the inlet cap body has an outer cap enclosing an inner cap, the outer cap having a convoluted wall. An inlet conduit termination fitting has an outboard fitting section, with an o-ring in a circumferential groove, disposed inside the inlet cap, and an inboard fitting section attached to the inlet conduit outboard end. A cap heat shield encloses the inlet cap and a conduit heat shield is attached to the inlet conduit. The lubricant inlet assembly is mounted to an engine casing with a low-conductivity insulating gasket between the cap base and the engine casing.

Abstract: The invention provides a method and apparatus for generating a signature signal which indicates a probable location for an error-causing mechanism within a digital system, where the digital system has control-signal and data-signal carrying busses and error detection means for detecting error conditions in the signals carried by those busses. The signature generating method comprises the steps of: counting the total number of errors detected by the error detection means during a signature generating run; and counting the number of errors detected by the error detection means during a signature generating run where those errors were accompanied by the presence of accompanying signals on the signal-carrying busses, the accompanying signals being ones which belong to a predefined subset of all signals appearing on the system signal-carrying busses.
