Title: Anti-etch bottle washing solution
Inventor: ROUILLARD CAROL A
IPC: C11D3/02
Filed: 1997-03-20
Abstract: Chemical etching of bottles in a bottle washer is minimized by soaking the bottles in a highly caustic composition which does not include any phosphorus compounds, ethylene diamine tetraacetic acid or nitrilotriacetic acid. The soaking composition includes the sodium hydroxide dissolved in water, in combination with polycarboxylic acid crystal growth inhibitors. Preferably, the soaking solution further includes a nonionic surfactant such as an alkyl polyglucoside, as well as a chelant such as a gluconate, glucoheptonate, or boroheptonate. The soaking solution can be added by either combining a liquid or powder build detergent composition which also forms a portion of the present invention or, alternately, an additive package, not including the sodium hydroxide, can be added. These compositions effectively clean the bottles and significantly reduce the dissolution of the glass which can, in turn, cause a hazing and weight loss. This also reduces the amount of silicate scale formed in the bottle washing apparatus.

Title: Steam cooling apparatus for gas turbine
Inventor: TAKAHAMA MASAYUKI
IPC: F01K23/10
Filed: 1998-06-24
Abstract: Disclosed is a steam cooling system for gas turbine combustors, in which steam valve 12 is opened and steam from boiler 4 is conducted, and thereby a combustor of gas turbine 1 is cooled, and steam recovery valve 11 is opened and this steam is returned to steam turbine 5. When the amount of steam at the combustor outlet decreases, the temperature of temperature sensor 3I increases, and when this exceeds a predetermined value, temperature regulating valve 30 is opened and steam from steam turbine 5 is extracted and is let into the cooling steam outlet side flow path 61 through a steam flow path. When the value of pressure sensor 24 reaches a predetermined value, bypass valve 14 is opened and steam is caused to flow to condensor 6, and the necessary amount of steam is maintained within the combustor. This is all controlled by means of controller 10, which constantly maintains the temperature of the cooling steam at predetermined values.

Title: Integrated performance support system protocol
Inventor: ROBERT JEAN
IPC: G06Q10/00
Filed: 1999-03-03
Abstract: A computer-implemented integrated performance support system is described. The integrated performance support system uses a predefined message protocol for sending user support request messages from computer-implemented user applications to a performance support engine which retrieves performance support information from one or more databases and presents it to the user.      The integration permits multiple application support and cross-training for an individual who must use more than one computer-implemented tool to perform a job function.      The advantage is a standard for integrating a user support environment with more than one product, allowing simple and standardized inclusion of new products and support methods into the environment.

Title: Self-centering phakic intraocular lens
Inventor: ROZAKIS GEORGE W
IPC: A61F2/16
Filed: 1997-10-23
Abstract: The invention is a phakic intraocular lens (IOL) for the correction of visual disorders such as myopia, hyperopia, astigmatism and presbyopia. The lens is made from a biocompatible, elastomeric material such as silicone. The lens further includes one or more annular surfaces that protrude from the anterior surface of the lens or surround the lens such that when placed in the eye, it makes contact with the iris. As the iris dilates and constricts, the contact with the iris places a centering force on the implanted lens. The lens is not in contact with the natural lens of the eye and floats in the posterior chamber without insult or abrasion to surrounding tissue.

Filed: 1998-02-11
Abstract: A medical device for estimation of pulmonary wedge pressure (10) wherein a nonoccluded pulmonary artery blood pressure measurement device (13) is utilized to directly estimate the pulmonary wedge pressure.

Title: Stranded synthetic fiber rope
Inventor: DE ANGELIS CLAUDIO
IPC: B66B7/06
Filed: 1999-10-21
Abstract: With reference to a rope of load-bearing aramide fiber strands (9, 10, 11) laid parallel to each other in concentric layers of strands (14, 16), it is proposed to lay the strands (12) of an outermost layer of strands (12) with opposite lay to the rope core (19). As a result of the opposite lay, the torques which occur in the layers of strands (14, 16, 21) when under load cancel each other out; a non-twisting rope structure is achieved. An elastic intersheath (20) between the oppositely laid layers of strands (16, 21) serves to protect the strands (10, 11, 12) against abrasion and to transmit the torque over a wide area in the elevator rope (1).

Title: Method and apparatus for improving lasik flap adherence
Inventor: KAWESCH GLENN
IPC: A61F9/01
Filed: 1999-10-29
Abstract: A method and apparatus, which provides improved conditioning and adherence of a resected corneal flap into its original position on the eye following the laser ablation step of LASIK vision correction surgery is disclosed. The method comprises resecting at least a portion of at least one of a person's eyes to expose an inner layer of said cornea, which is sculpted using radiation from a laser beam to produce a desired corneal topography. After the desired topography is achieved, the corneal flap is floated back into its proper position in a sterile solution and to remove any debris associated with the sculpting step from the patient's eye. After the corneal flap is repositioned, a flap drying apparatus is used to dry the repositioned corneal flap by applying filtered, compressed air at a flow rate substantially between zero and 2.5 liters per minute at an appropriate pressure to draw the sterile solution away from the corneal flap/inner corneal layer interface without disturbing the positioned or alignment of the repositioned corneal flap. An ophthalmic surgeon observes the corneal flap using a microscope while applying the filtered, compressed air to the corneal flap, for substantially between 15 and 30 seconds, paying particular attention to a gutter area surrounding corneal flap. The surgeon terminates the application of the filtered, compressed air when the gutter area is observed to be substantially dry.

Title: System and method for noise threshold adaptation for voice activity detection in nonstationary noise environments
Inventor: MALAH DAVID
IPC: G10L25/78
Filed: 1999-02-26
Abstract: The system and method of the invention relates to voice detection technology for determining instants of time at which a snapshot of noise characteristics results in improved adaptation of noise floors used in voice detection. The approach is based on the "lower envelope" of the smoothed input signal power.  Incorporation of this approach in a simple time domain VAD (Voice Activity Detector) results in an effective low-complexity system which, on the basis of simulations, gives good performance down to SNR values of about 0dB. In the invention the lower envelope also provides the updated value of the noise threshold during the presence of speech. The invention can also be embedded in other, more complex (e.g., frequency domain) VADs at low computational cost.
