Title: Trochlea shaping instrument for fitting femuro-patella prosthesis
Inventor: LABOURDETTE PATRICK
IPC: A61F2/38
Filed: 1994-06-16
Abstract: The instrument consists of an intra-medullary guide (3) which is inserted into the distal end of the femur along its anatomical axis, a support (17) mounted on the guide, and a cutter guide (26) to receive a cutter (1) in the shape of a cylinder with a surface which can wear or file the surface of the trochlea when rotated by its drive shaft (34).

Title: Alignment and focusing adjusting method for multiple beam power laser
Inventor: DELON MICHEL
IPC: H01S3/23
Filed: 1994-07-29
Abstract: The method involves using a controller which provides laser impulses, and an assembly which carries out spatia-temporal amplification and filtration of the impulses. Laser beams, e.g. from solid state laser, are transmitted by optical fibre and by reflectors to a target. The laser beam is injected into an amplifier cavity by two movable mirrors (K1,K2) to pass through a first filter aperture (T1). The amplifier is provided with at least two amplifiers (241,242) and at least one return mirror (M1,M5). The adjustment of two sets of filter apertures (U1-U4,T1-R4) corresponding to four paths of the beam involves adjusting the first aperture position by angling a return mirror (M1) to centre it on the filter apertures (U2,T2) of one of the second filters. The image of the reticule (RI) is made to coincide with a reticule (C1) behind the return mirror by adjustment of the movable mirrors in each propagation line.

Title: Tubular vessel sealed by frozen static valves for lysis of cells
IPC: F16K13/10
Filed: 1995-02-13
Abstract: A static valve (1) consists of a piece of tubing (2a) containing a fluid (2b).

Title: Surface mounted coaxial switch for electrically connecting radio transmitter to antenna, e.g. on vehicle
Inventor: JAUNEAU ALAIN
IPC: H01R13/646
Filed: 1995-04-19

Title: Controlling sub-operating system in message exchange database
Inventor: PARK NAM HOON
IPC: H04L29/06
Filed: 1995-06-12
Abstract: The sub-operating system converts a message using a sub-system of the target interface to a format suited to the target sub-system. Each message has an identifier number. If the identifier is 1, the message is formatted for the operating system unit handling data transfer along a communication network. When the identifier is 0, the message is formatted to be compatible with a database held in the sub-operating system, and the resulting message stored in the database.  An identifier of 2 causes the message to be formatted to deliver output to user or printer. An identifier of 3 causes the message is coded for the user interface, and 4 causes the message to be transmitted through an interface card.

Patent FR-2743892-A1 (FR)
Inventor: SICRE JEAN LUC
IPC: G01S3/48
Filed: 1996-01-19
Abstract: An aircraft piloting aid system mainly used during take-off and landing under adverse visibility conditions is disclosed. To make use of head-up displays which display artificial horizon line, aircraft pitch attitude and ground speed vector symbols without using an inertial reference system (IRS) to provide heading and attitude data, a non-inertial attitude heading reference system (AHRS) combined with a compass is used and data therefrom is periodically corrected in order to display attitude symbols by means of corrected data rather than raw data from the AHRS. Correction is provided by two GPS receivers (GPS1, GPS2) connected to antennas (A1, A2) on top of the aircraft, and an interferometric RF carrier phase measurement is performed to determine an aircraft direction vector. The system is useful for modernising aircraft fitted with non-inertial AHRSs to enable take-off and landing under all conditions, including conditions of very poor visibility.

Title: Production of potable water from waste or sea waters
IPC: C02F1/14
Filed: 1996-12-04
Abstract: Drinking water is produced from non-potable water sources, such as waste waters or sea water, by evaporation. Water for processing is settled in a decantation tank (1) where solids are removed (9) if necessary. Some water evaporates in the heat of the sun and condenses on the underside of the sloped glass vessel roof (5). This condensate trickles down the roof and is collected (7). Remaining water passes into a second evaporation vessel (10), also with a glass roof where more is evaporated, condensed and collected (21). Collected distilled water is finally mineralised (23) to provide palatable drinking water.
