Title: Fan and compressor noise attenuation
Inventor: TSE MAN-CHUN
IPC: B64D29/00
Filed: 1999-12-22
Granted: 2010-03-30
Abstract: The present invention is a noise attenuation system and related method for suppressing noise having a primary tone generated by a jet engine. An exciting sound wave generator is positioned within the nacelle of the jet engine at its inlet to generate an exciting sound wave having a primary frequency generally different from a frequency of the primary tone of the noise. The exciting sound wave is used to modulate the primary tone of the noise and, therefore, distribute sound energy of the noise from the primary tone to a broad range of side bands so that the amplitude of the primary tone of the noise is reduced. The exciting sound wave generator according to the preferred embodiments is a fence member exposed to the air flow entering the inlet of the nacelle, or an aperture defined in the inner wall of the nacelle to jet a air flow into the nacelle. The noise attenuation system avoids complicated noise attenuation devices used in an active noise control system for sensing the noise frequency and phase, and controlling the frequency and phase of the generated sound wave for a match.

Abstract: A disposable cup lid is provided for placement onto a drinking cup having a substantially circular cup rim which lies substantially in a single plane. The cup lid comprises a substantially circular and substantially planar top surface, and a downwardly facing cup rim engaging recess formed near the outer periphery thereof. The cup rim engaging recess extends from 300° to 360° around the periphery, and is defined at its outer side by a substantially circular, downwardly depending apron, at its inner side by a first downwardly directed recess sidewall, and at its top by a top wall between the downwardly depending apron and the downwardly directed recess sidewall.  The downwardly depending apron extends 360° around the periphery.  There is an arcuate portion of the top surface which extends radially outwardly to the downwardly depending apron, and which has a radially directed axis of symmetry. A  depressed "U"-shaped hinge is formed in the top surface in the region thereof occupied by the arcuate portion, and the "U"-shaped hinge is oriented so as to be perpendicular to the axis of symmetry. A fault line is stamped into the top surface in the arcuate portion, in a location opposed to the "U"-shaped hinge. The fault line is spaced radially inwardly from the downwardly directed apron by a distance which is at least equal to the width of the top wall of the cup rim engaging recess; and the fault line defines an outer extremity of a tear-back flap which, when torn back, will fold backwardly at the "U"-shaped hinge and will thereby define a drink-through opening in the top surface. Also, an upwardly extending lifting stub is formed in the arcuate portion of the top surface in a location thereof between the first fault line and the "U"-shaped hinge. The dimensions of the lifting stub are such that it may be easily grasped between the thumb and a forger of an adult hand, so that the tear-back flap may be torn back by a grasping and lifting action of the lifting stub, and so as to provide access to the drink-through opening.

Title: Natural gas composition transport system and method
Inventor: CAMPBELL STEVE
IPC: B63B25/00
Filed: 2000-02-28
Granted: 2009-01-20
Abstract: A compressed natural gas (CNG) transportation system designed to operate at or just below ambient temperatures, that is either ship-based, truck-mounted, or modular for container transportation. The system is an alternative to LNG, pipeline, or conventional CNG transportation systems, where the foregoing modes of transportation are not practical or feasible. The use of composite pressure vessels provides a critical advantage over conventional CNG concepts that use steel or steel lined pressure vessels. The rupture characteristics of composite pressure vessels exceed those of conventional steel or steel lined pressure vessels. The substantial weight reduction of pressure- equivalent composite pressure vessels overcomes the weight-related problems associated with steel or steel lined pressure vessel concepts. The corrosion resistance of composite pressure vessels allows for the transportation of raw CNG and or compressed natural gas liquids (CNGL) which are most often corrosive. The use of composite vessels with corrosion resistant liners removes the requirement to process the gas and or liquids at or near the source of supply.
