Patent EP-0222811-B1 (EP)
IPC: G01C19/64
Filed: 1986-05-09
Granted: 1990-11-07
Abstract: A method and apparatus for generating a plurality of electromagnetic signals, primarily optical signals, having linewidths centred on frequencies fixed relatively to a reference frequency. The apparatus comprises a reference frequency signal source such as a gas laser (1) which generates a reference signal having a frequency fP. This reference signal is fed to a leading one (3) of a plurality of optical fibre ring lasers (3, 11, 16) connected together in series by optical fibres (6, 12). The characteristics of the injected signal and the form of the waveguide ring (5) defined by the ring laser (3) is such that stimulated Brillouin scattering occurs in the waveguide ring to generate a scattered signal with a frequency fP-fA travelling in an opposite direction to the injected signal. This scattered signal is passed by the optical fibres (6) via an isolation device (7) to the next ring laser (11) in series. Directional couplers (2, 10, 15) are provided to guide the injected signals, including the reference signal to respective output ports (9, 14, 17). The stimulated Brillouin scattering effect causes each scattered wave to be offset from the corresponding injected wave by a fixed frequency (fA).

Granted: 1991-07-24
Abstract: The existing processes for the preparation of halogenoacrylic acids and deuterated derivatives thereof have to be carried out using chemicals which are in some cases very toxic or very expensive. Electrochemical reduction, however, makes it possible to eliminate one or more halogen atoms selectively from halogenoacrylic and halogenomethacrylic acids and derivatives thereof, and to replace these by hydrogen or deuterium atoms. This is effected by electrolyzing the acids or derivatives thereof in a solution containing water or deuterium oxide at a temperature from -10 DEG  C. up to the boiling point of the electrolysis liquid.

Title: Method and circuit arrangement for producing filtered signals
IPC: H04L25/03
Filed: 1988-09-21
Granted: 1993-03-31
Abstract: For correcting data signals transmitted by a two line duplex system filter signals are obtained from a transversal filter with inputs for different amplitude values, stored in the cells of a circulating memory. The values are verified and summed to obtain filter signal coefficients and corresponding summing signals, which are multiplied by a factor according to the amplitude values, and then summed again. A part of the resulting signal is multiplied with additional correction signal coefficients, and the resulting additional product signals are included to form the summing signal. The signal generating circuit includes a multiplexer supplying amplitude values to a further multiplexer and demultiplexer with summing memories, interconnected with an adding stage. This is followed by a second summing stage (ADDL) with two sets of multipliers.

Abstract: Cryptographic methods and apparatus for forming, checking, blinding, and unblinding of undeniable signatures are disclosed. The validity of such signatures is based on public keys and they are formed by a signed party with access to a corresponding private key, much as with public key digital signatures. A difference is that whereas public key digital signatures can be checked by anyone using the corresponding public key, the validity of undeniable signatures is in general checked by a protocol conducted between a checking party and the signing party. During such a protocol, the signing party may improperly try to deny the validity of a valid signature, but the checking party will be able to detect this with substantially high probability. In case the signing party is not improperly performing the protocol, the checking party is further able to determine with high probability wether or not the signature validly corresponds to the intended message and public key. Blinding can be used while obtaining undeniable signatures, while providing them to other parties, and while checking their validity.

Title: Procede pour determiner et evaluer la pression de combustion d'un moteur a combustion interne
IPC: G01M15/00
Filed: 1988-10-26
Granted: 1992-07-22
Abstract: Les procédés traditionnels pour déterminer la pression de combustion d'un moteur à combustion interne sont très onéreux et les capteurs utilisés doivent répondre à des exigences sévères. Le procédé décrit diffère des procédés précités en ce que l'on calcule la pression de combustion en déterminant la pression de compression pk(alpha) et en mesurant la pression de la chambre d'explosion p(alpha) au moyen de simples capteurs. On obtient la pression de combustion p*(alpha) en soustrayant de la pression de la chambre d'explosion la valeur de la pression de compression. On obtient de préférence la variation de la pression de compression en mesurant la pression de la chambre d'explosion pendant la compression jusqu'au point mort ou dans la phase d'explosion et en stockant les valeurs dans une mémoire. On obtient les valeurs de compression apparaissant après atteinte du point mort haut, par symétrie sur un axe passant par le point mort haut, ce qui donne une courbe symétrique de pression de compression. On peut ainsi calculer très facilement la pression de combustion.

Abstract: In a cell analyze apparatus, a light beam is irradiated onto cells (or particles like the cells) flowing through a flow cell so as to measure cell light information for each cell with respect to a plurality of parameters (for example, the forward scattered light intensity, the right angle scattered light intensity and the intensity of fluorescence by different dye). Eased on a minimal point of a histogram associated with the cell light information with respect to one or more parameters, the cell population is subdivided into fractions. When the minimal point is missing in the histogram, the parameters above are converted by use of a predetermined conversion expression (for example, a coordinate conversion is effected on the parameters) such that a minimal point is detected from the histogram of cell light information related to the new parameters obtained by the conversion, thereby subdividing an objective cell population.
