Title: Improvements relating to antimicrobial cleaning compositions
Inventor: ALLAN ALEXANDER
IPC: C11D3/37
Filed: 1995-11-28
Abstract: The invention relates to a disinfecting composition of pH 2-7 comprising: a) 1-30 wt.% on product of an ethoxylated nonionic surfactant; b) less than 50 wt.% of total surfactant of anionic surfactant; c) 0.005-5 wt.% on product of a water-soluble, anionic polymer having an average molecular weight of less than 1.000.000, wherein, the ratio of polymer:nonionic is 0.1:1 or less; and d) 0.1-15 wt.%  on product of an antimicrobial agent selected from the goup comprising:  benzoic acid derivatives, dicarboxylic acids, C1-C6 alkanols and mixtures thereof. It is believed that a marked synergy is exhibited between surfactants selected from the group comprising amphoteric surfactants and alkoxylated alcohol surfactants (which are otherwise poorly biocidal) and the selected organic acids and alcohols. In the presence of the polymers the synergy is maintained and exploited to give a product which is an effective cleaner and an effective biocide. The invention also extends to a process for disinfecting non-living surfaces which comprises the step of treating the surface with a composition as given.

Abstract: L'invention se rapporte à un procédé qui permet de déterminer le risque de thrombose chez un individu. Ce procédé consiste à déterminer l'activité de la protéine C et de la protéine S dans le plasma d'un individu dont on pense qu'il court le risque d'une thrombose, par addition dans un échantillon de plasma prélevé sur la personne (i) d'un premier réactif dans une quantité suffisante pour induire ou activer la coagulation à l'intérieur du plasma, (ii) d'un deuxième réactif qui active la protéine C endogène dans le plasma, et (iii) d'un troisième réactif comprenant des sels de calcium, des phospholipides ou la thromboplastine tissulaire, ou bien une combinaison de ces constituants. A un second échantillon de plasma prélevé sur la même personne, on ajoute un réactif qui induit ou active la coagulation, ainsi qu'un tampon ou autre matériau n'activant pas la protéine C, ainsi qu'un troisième réactif correspondant à la description du troisième réactif ci-dessus. On mesure le temps et/ou la vitesse requis de conversion du fibrinogène endogène en fibrine dans les premier et second échantillons. On réitère les mêmes opérations sur du plasma de contrôle normal et, ensuite, on évalue la différence ou le rapport des temps et/ou vitesses ainsi obtenus. La différence ou le rapport donne une indication sur le risque thrombotique chez la personne. On décrit par ailleur un kit approprié à la mise en oeuvre du procédé. Les procédés et les kits décrits dans d'autres modes de réalisation peuvent comporter un premier réactif ayant un support synthétique, un deuxième réactif qui active la protéine C dans l'échantillon prélevé sur la personne et, dans le second échantillon un deuxième réactif qui n'active pas la protéine C. Dans ces modes de réalisation, on mesure et on compare les vitesses d'hydrolyse des supports synthétiques.

Title: A peak limiter for suppressing undesirable energy in a return path of a bidirectional cable network
Inventor: WILLIAMS THOMAS H
IPC: H04B10/12
Filed: 1998-06-01
Abstract: A system for preventing the distortion of data signals in a return frequency band by a laser on a return path of bidirectional communication network. The distortion of data signals is prevented by minimizing strong noise energy in thereturn band. The return frequency band is divided into a lower return frequency band and an upper return frequency band. The lower return band contains frequencies overlapping a noise floor with strong noise signals. The splitting of the upper and lower return frequency bands allows the upper return frequency band tobe unaffected by the strong noise signals. The distortion by the strong noise signals on data signals at adjacent frequencies is minimized by transforming signals in the lower return frequency band to another form of signals that are not affected by strong noise energy.

Title: Method and apparatus for determining the speed and location of a vehicle
Inventor: GATSONIDES TOM
IPC: G01S13/92
Filed: 1997-04-01
Abstract: The invention relates to a method for measuring the speed of a vehicle by transmitting a wave beam directed at the vehicle, receiving a part of the wave beam reflected by the vehicle, comparing the reflected beam part with the transmitted wave beam and deriving from this comparison the speed of the vehicle, wherein during the speed measurement the position of the vehicle is also determined. A vehicle committing an offence can thus be identified unambiguously in a recording which is made after detection of the speeding offence.      The speed of the vehicle can be determined from a difference in wavelength detected during the comparison between the reflected beam part and the transmitted wave beam, while the position of the vehicle is determined from a time lag detected during the comparison between the moment of transmitting and the moment of receiving the reflected beam part. The invention also relates to an apparatus for performing this method.

Abstract: A capacitive electroacoustic transducer (10) which includes an electrically insulative substrate (19), a layer of conductive material disposed (16) on a portion of a top surface of the substrate forming a first electrode of the transducer, a conductive diaphragm (22) forming a second electrode of the transducer which is deflectable in relation to the first electrode, and a structure (18) for electrically and physically separating the first and second electrodes in spaced relationship so as to constitute a capacitor. This transducer exhibits a high degree of thermal stability partly due to the substrate and diaphragm being made of materials having closely matched thermal expansion coefficients. This feature ensures that the tension in the diaphragm stays consistent even with varying temperatures, thereby maintaining a constant transducer sensitivity. In addition, the distance separating the first and second electrodes is minimized so as to create a short thermal expansion path. This short path length minimizing changes in the response of the transducer due to variations in temperature. This transducer can also be batch produced.
