Abstract: A speech processor uses at least two speech processing features to enhance the quality of speech signals received by a user during a telephone call.  The speech processing features are applied to the speech signals.  However, the user only hears speech signals affected by one speech processing feature until both features have fully converged or ramped-up, and the two features are no longer interfering with each other.  At that point, a "flash-cut" of the second speech processing feature is activated.  The flash-cut instantaneously switches to speech signals affected by both features. This quick transition makes the speech processing features more noticeable to the user, and the user is not subjected to the period where the features interfere.  Further, an optional audio indicator is generated before implementing the flash-cut, so the user is alerted to the flash-cut, and the speech processing features are even more noticeable.

Abstract: A method and a system for offshore production of liquefied natural gas, wherein natural gas is supplied from an underground source (4) to a subsea production plant (1). The gas is transferred under a high pressure directly from the production plant (1) to an LNG tanker (6), the transfer taking place through a pipeline (5) surrounded by sea water and causing the temperature of the high pressure gas to be lowered to a desired low temperature. This gas is supplied to a conversion plant (12) provided on the LNG tanker (16) and arranged for converting at least a part of the gas to liquid form, and the liquefied gas is transferred to storage tanks (17) on board the vessel (6). When the storage tanks (17) on the LNG tanker (6) are filled up, the pipeline is disconnected from the LNG tanker and connected to another similar tanker, the pipeline being permanently connected to a submerged buoy (8) which is arranged for introduction and releasable securement in a submerged downwardly open receiving space (11) in the tanker (6), and which is provided with a swivel unit for transfer of gas under a high pressure.

Abstract: A sealed contactor for switching electric current has a switching assembly that includes a movable contact which selectively bridges a pair of stationary contacts to provide an electrical path therebetween.  The moveable and stationary contacts are mounted to a body of electrically insulating material to form a unitized structure.  A separate actuator assembly has an enclosure which contains an electrically operated driver with a linkage that extends into the switching assembly to alternately operate the moveable contact into engagement with and disengagement from the stationary contacts.  The switching assembly is sealingly attached to the actuator assembly in an interlocking manner that prevents arcs produced between the contacts from escaping outside the electric current switching apparatus.          Nevertheless, the switching assembly is capable of being easily removed and replaced as a single unit from the actuator assembly when repairing the contactor.
