Abstract: A seal including a body (11) with a recess (8) at one end engageable by a spanner, and a screw thread (2) at the other end for engaging a complementary screw thread (7) in an opening (6) of a housing (3). A locking ring (31) biased by a spring in the seal (1) and a complementary locking ring (47) in said opening have asymmetrical teeth which interlock when screwing-in is complete and snap together to prevent loosening of the rings. The tooth flanks that engage one another on loosening are nevertheless sufficiently angled to enable forced unscrewing using a spanner. A skirt (14) protects the mechanism and acts as an abutment in the fully screwed-in position. Said seal enables locking and unlocking, requires no direct manual operation and is particularly suitable for endoscope insertion openings in aircraft engines.

Title: System and method of local data alignment for stack memory
Inventor: STOODLEY KEVIN ALEXANDER
IPC: G06F9/45
Filed: 1997-07-25
Granted: 2001-12-11
Abstract: A system and method for aligning data in stack memory in a data processing system where the stack memory provides temporary storage for storing parameters for a function call. The method first determines if any of the parameters in the function being call are of a selected type. If a parameter is of a selected type, code is generated for aligning the parameter on a stricter boundary than the default boundary for the stack memory. Code is then generated to align the remaining parameters in the function call on the default boundary in the stack memory. The aligned parameter in the stack provides a reference point which is used by the called function to align locally scoped variables in the stack. By aligning a parameter of a selected type on stricter boundary in the stack, for example, a double precision floating point aligned on an 8 byte boundary, the execution performance of the compiled program code is improved.

Granted: 2007-08-21
Abstract: A dual port frequency modulator and method for eliminating the undesired effects caused by high port/low port phase differences in a standard dual port frequency modulator. The frequency modulator includes an inverse filter stage coupled to the input of a modulator stage including a first high port processing path for processing high frequency components of a modulation signal and a second low port processing path for processing low frequency components of a modulation signal. The outputs of the high and low paths are coupled to separate ports of a voltage controlled oscillator. The impulse response of the inverse filter is designed to be the inverse of the impulse response of the modulator stage. The filter functions to counteract the adverse effects caused by the delay difference in the high and low processing paths of the modulator stage such that the overall response of the dual port frequency modulator is significantly improved.
