  • Patent number: 5726575
    Abstract: The invention relates to an acquisition path for acquiring a voltage pulse, and to a system and a method making use of said path, the path comprises:a path input for a pulse signal;a module for determining the polarity and for limiting acquisition of the input signal;a control module for controlling acquisition and for storing the polarized peak value of the input signal;a detect-and-hold module for detecting the polarized peak value of the signal being acquired, and for holding it; andselection means for selecting the rating of the signal being acquired;according to the invention the selection module for selecting the rating of the signal being acquired comprises a plurality of measurement ranges all of which are connected at their upstream ends to the path input, and all of which are connected at their downstream ends to automatic selection means for automatically selecting the optimum measurement range for the signal being acquired.

  • Patent number: 4388449
    Abstract: The invention relates to a novel thermoplastic monoorganopolysiloxane resin comprising units of the formula RSiO.sub.1.5 and R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 wherein R,R.sub.1,R.sub.2 and R.sub.3 are hydrogen, or organic groups which may be the same or different, at least 85% of the R groups in the RSiO.sub.1.5 being organic groups, and at least two of the groups R.sub.1, R.sub.2 and R.sub.3 in each R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 unit being organic groups, and in which the ratio RSiO.sub.1.5 units to R.sub.1 R.sub.2 R.sub.3 SiO.sub.0.5 units is from 1:0.005 to 1:0.03 on a molar basis. Such resins are useful as electrical insulation material and as hold out agents for heat recoverable materials.

    Inventors: Jean-Claude Bonnet, Kenneth B. Pithouse
  • Patent number: 4387196
    Abstract: The invention relates to a novel process for the production of a thermoplastic, high softening point polysiloxane resin which comprises reacting a solvent-soluble partially condensed organosiloxane with a silane capping agent. The resins so produced are useful as electrical insulator material and also as hold out agents for heat recoverable articles.

  • Patent number: 4075177
    Abstract: A cationic resin which is thermally settable or thermally hardenable, for use in improving the moisture resistance of cellulosic fibrous materials such as paper, is produced by reacting at least one dicarboxylic acid with a mixture of at least one polyamine and at least one dialkanolamine to produce a polyamide-polyester copolymer soluble in water and subsequently condensed with epichlorohydrin.

  • Patent number: 4058498
    Abstract: A process for preparing liquid treating agents, stable under storage, especially for improving the wrinkle-free characteristics of cellulosic textiles treated with the liquid in which urea is condensed with formaldehyde in an aqueous solution in the presence of glyoxylic acid. This condensation is carried out in a first step using an acid pH between 2 and 5 with a molar ratio of urea/formaldehyde/glyoxylic acid of 1 : 2 to 10 : 0.03 to 0.6 and at a temperature between 20.degree. and 100.degree. C. In a second stage the reaction is carried out at a slightly acidic pH between 6 and 7 at a temperature between 20.degree. and 60.degree. C with addition of a fresh quantity of urea and eventually a fresh quantity of formaldehyde in an aqueous solution so as to obtain an overall molar ratio of urea/formaldehyde/glyoxylic acid of 1 : 1.5 to 3.5 : 0.03 to 0.6.
