IPC: H04S7/00
Filed: 2003-03-31
Abstract: A compact sound processing system and method for use with a plurality of sound radiators. A microcontroller accepts a plurality of user-selected speaker equalization and space equalization settings and receives a paging control signal from a telephone interface. An analog mixer combines music signal inputs and a paging signal. A digital signal processor generates and filters masking noise, and processes the masking noise and combined music and paging signals based on user-selectable settings for distribution to the sound radiators. An audio amplifier modulates and amplifies the output signal from the digital signal processor, and delivers the output signal to the sound radiators via a transformer in defined zones. The sound radiators can be flat panel -sound radiators or conventional type speakers. A masking filter used with the masking noise generator can be programmed to shape the virtual random noise generated by decreasing the noise at a constant rate over the frequency range of human speech. A paging over music function reduces the music sound level by a preset amount whenever a paging control signal is received. A talkback controller is also provided to enable an individual to respond to a page using the sound radiator as a microphone.

Title: Method and apparatus for the measurement of intra-abdominal pressure
Inventor: SKOVLUND ERIK
IPC: A61B5/00
Filed: 2001-12-02
Abstract: A method and apparatus (10) for measuring the intra-abdominal pressure within a patient (12). A reservoir (20) is positioned between a drainage catheter (14) (e.g. a urinary catheter or naso-gastric tube) and a collection container (18) for the fluid being drained from the patient's body. The reservoir (20) defines a constant volume and receives the withdrawn fluid through a manometer tube having a series of markings.

Title: Power socket device with enabling switch and method of operation
Inventor: EL-HAJ ALI
IPC: H01R31/06
Filed: 2001-11-15
Abstract: A socket (10) provides power to a mating connector plug when actuated by a switch (22) integral with the socket (10). The switch (22) can be actuated by insertion of the connector plug, by pivoting open a socket cover (16), by sliding a slide cover into an operational position, or by a combination of the above. The switch (22) is isolated from the power supplied to the socket (10) and acts as a power supply signal to enable socket power. The socket (10) is powered only when needed as indicated by the actuation method, thereby reducing draw on a power supply connected to the socket (10). The switch (22) actuation methods described also provide safety features by disabling power to the socket (10) unless the socket (10) is actually in use. The socket cover (16) and slide cover also prevent access to the socket (10) unless positioned to receive a connector.

Title: Process for obtaining an organic acid from an organic acid ammonium salt, an organic acid amide, or an alkylamine organic acid complex
Inventor: COCKREM MICHAEL CHARLES MILNER
IPC: C07C51/02
Filed: 2002-03-06
Abstract: A method for the recovery of an organic acid, such as a heat stable lactic acid, from a feedstream (1) comprising at least one of an organic acid amide, an organic acid ammonium salt or an alkylamine-organic acid complex. The feedstream is mixed with at least one azeotroping agent (2) and the mixture fed to a fractional distillation apparatus or reactor (3). The azeotroping agent is a hydrocarbon capable of forming at least one azeotrope with the organic acid that is produced by the thermal decomposition of the amide, ammonium salt, or complex in the feedstream. The mixture is heated to produce vapor stream (11) that comprises an azeotrope. The vapor stream can be condensed in condenser (12) to a liquid stream, and the organic acid is recovered in the liquid stream that is produced. When the azeotrope is a heteroazeotrope, the vapor stream can be condensed into a liquid stream, which can be separated into a first phase (18) and a second phase (17). The first phase contains the highest concentration of organic acid and the second phase comprises azetroping agent. The organic acid can be further purified and/or concentrated from the separated first phase or form the liquid stream.

The fingers are meshed and pivotally joined to respective spindles projecting radially from the open center of a ring spyder. The protective bellows, hose or resilient compound filled sheath is secured at opposite ends to bore plugs in the respective instrument housings. Between the instrument housings, the hose, bellows or filled sheath passes through the open center of the spyder ring.

Title: Improved rectangular brilliant-cut diamond
Inventor: MATSUMURA TAMOTSU
IPC: A44C27/00
Filed: 2003-10-23
Abstract: A diamond is provided which is subjected to an improved rectangular brilliant- cut producing a facet configuration having an optimal shape for the purpose of increasing the visual-perceptible reflection ray amount. In the rectangular brilliant-cut diamond, the bezel facets at the four crown vertexes each is bent along the diagonal line parallel to the girdle, to yield the facet configuration in which the bezel facet is divided into the lower bezel facet and the upper bezel facet. The upper crown angle of an upper bezel facet can be made smaller than the crown angle of a lower bezel facet, and hence even without altering the crown height, by making the table facet slightly smaller, the tilt angles from the horizontal of the star facets and the second bezel facets, both provided with intense reflection, can be made small and the areas thereof can be made large. Thus, the reflection patterns become all alike in size in a manner preferable for the visual perception, and making the star facets and the second bezel facets have small tilt angles from the horizontal permits making the reflection extremely intense in cooperation with enlargement of the areas of the star facets and the second bezel facets. -26-
