1.WO/1994/008243FLOW INJECTION BACK TITRATION

WO - 14.04.1994

国际分类 G01N 31/16 申请号 PCT/EP1992/002247 申请人 DOW BENELUX N.V. 发明人 EIKELBOOM, Pleun, Pieter

A method of flow injection back titration is disclosed for providing on-line chemical analyses of a process stream where the species of interest is not directly titratable. A stream of titrant is formed and then a sample and an excess of back-titrant are added to the stream of titrant. The back-titrant is allowed to react with the sample and then the remaining back-titrant is reacted with the titrant. The reaction is monitored, and the concentration of the component of interest in the sample is determined from time it takes for the back-titrant to be substantially consumed by the titrant.

2.WO/1997/043535TURBOFAN THRUST REVERSER WITH DOORS EQUIPPED WITH DEFLECTING BLADES

WO - 20.11.1997

国际分类 F02K 1/70 申请号 PCT/FR1997/000817 申请人 SOCIETE HISPANO SUIZA 发明人 GONIDEC, Patrick

The invention features a turbofan thrust reverser comprising pivoting doors (7) integrated in direct jet flow in the external pod wall and constituting thrust reversing flow deviation obstacles after pivoting by an actuator (8). Each door (7) bears at least one deflecting blade (22) aerodynamically profiled in wing shape, set in contact with the flow in the ring-shaped channel (21) such that the flow exerts an action on the said blade (22) which tends to maintain the door (7) in its closed direct jet position.

WO - 18.03.1993

国际分类 F02K 1/56 申请号 PCT/FR1992/000850 申请人 HISPANO SUIZA S.A. 发明人 CARIMALI, Félix

A turbo-jet thrust reverser comprising movable elements (7) which, when closed, are incorporated into the outer wall of the turbo-jet pipe, and, when open, may deflect the flow in said pipe. Blade-shaped elements (23) are arranged within each movable element (7) on the upstream side thereof and evenly spread out over the width thereof in a direction which is generally parallel to the geometrical thrust reverser axis, whereby deflecting walls for controlling reversed-flow layers are formed.

4.WO/1992/018865IMMUNOASSAY FOR THE DETECTION OF HIV SPECIFIC IgM

WO - 29.10.1992

国际分类 G01N 33/569 申请号 PCT/US1992/002585 申请人 CEDARS-SINAI MEDICAL CENTER 发明人 BRUNELL, Philip, Alfred

A method of immunoassay for detecting antibodies to human immunodeficiency virus (HIV). The assay detects HIV specific IgM antibody thereby distinguishing those infants who are infected with HIV from those who have passively acquired maternal HIV specific IgG antibodies. Additionally, the assay can be used to detect individuals infected with HIV who have not yet mounted an IgG immune response.

5.WO/1998/029654THRUST REVERSER FOR A BYPASS TURBOJET WITH DOWNSTREAM BUCKETS

WO - 09.07.1998

国际分类 F02K 1/70 申请号 PCT/FR1997/002338 申请人 HISPANO SUIZA 发明人 GONIDEC, Patrick

Disclosed is a thrust reverser for diverting the bypass flow of a bypass turbojet, comprising shiftable elements or buckets (17). At least one downstream portion of each bucket covers, in the direct flow, a portion of a fixed structure (20) which forms the outer wall of the bypass flow canal, the outer surface of said bucket (17) forming a portion of the outer pod surface. Attachment, retention, and guidance during the displacement of the bucket (17) are ensured by a system of connecting rods placed upstream (36) and downstream (27), said rods (27, 36) being situated on the fixed structure of the pod and disposed in the direct flow inside the thickness of the fixed beam that separates two buckets (17).

6.WO/1998/030794THRUST REVERSER WITH BLADE ROWS WITH OPTIMISED ACTUATOR CONTROL

WO - 16.07.1998

国际分类 F02K 1/72 申请号 PCT/FR1998/000032 申请人 HISPANO SUIZA 发明人 VAUCHEL, Guy, Bernard

The invention concerns a turbojet thrust reverser comprising a mobile shroud (7) capable of being displaced in translation downstream by means of actuators (4) uncovering blade rows (13) and driving flap shutters (12) pivoting about an articulation (15) integral with the internal wall (16) of the annular channel (17), by means of connecting rods (14), so as to close the channel (17) or to deviate the flux ejected through the rows (13), providing thrust reversal. The longitudinal geometrical axis of the actuator (4) is in line with the link (9) with the mobile shroud (7) and with a contact point (2), at the level of the device for installing the reverser, between a blade (3) integral with the fixed upstream reverser structure (6) and an interface flange (5) integral with the casing of the turbojet.

7.WO/1996/019641PROTECTIVE SHIELD FOR A TURBOMACHINE

WO - 27.06.1996

国际分类 F01D 21/04 申请号 PCT/FR1995/001698 申请人 SOCIETE HISPANO SUIZA 发明人 GLOWACKI, Pierre, Antoine

Shield for protecting the outer fairing (3) of a turbomachine. Said shield consists of a ring of ductile material retained by fastening means with fairly easy breaking properties. When a piece of the rotor (17) comes loose accidentally and impacts said shield, the denting caused ruptures some or all of the fastening means. This allows the shield (9) to undergo considerable deformation thus enhancing its energy absorbing capability.

8.WO/1993/005591SIGNAL LEVEL CONTROL IN A FIBER COMMUNICATIONS SYSTEM

WO - 18.03.1993

国际分类 H03G 3/20 申请号 PCT/US1992/007326 申请人 SCIENTIFIC ATLANTA, INC. 发明人 LITTLE, Frank, R.

The system provides level controls at both transmitter and receiver ends of the fiber transmission system, utilizing compensation and control techniques at each end to maintain and optimize the performance of the system. The transmitter includes two stage level control based on a composite power level of a detected RF signal. The receiver includes two stage level control based on a pilot channel filtered from the channels transmitted to the receiver.

9.WO/1993/005621OPTICAL SWITCHING IN A FIBER COMMUNICATION SYSTEM
