Title: New monoazo-pyrazolone-dyestuffs containing a cyanuric residue and process for their manufacture
IPC: C09B43/16
Filed: 1957-01-18
Abstract: The invention comprises dyes of formula:  <FORM:0840742/IV (c)/1> where R is a benzene residue, R1 and R2 each represent a carbon-containing substituent and together contain at most 16 C atoms, and Pz is a 5-pyrazolone residue bound in the 4-position to the azo link, and the aryl residues in the dye molecule together have, at most, 2 SO3H groups.  They are made by coupling appropriate diazo compounds containing the triazine residue with the required pyrazolones, or the triazine residue may be introduced into an appropriate monoazo dye. Alternatively dyes may be made in which R1 and/or R2 of the above formula are Hlg (see Specification 775,308) which are subsequently reacted with appropriate reagents to introduce R1 or R2.  Preferably Pz is a 3-methyl-5-pyrazolone residue and R1 and R2 each represent a substituent bound directly or advantageously via a nitrogen bridge to the triazine members and together contain 6-12 C atoms.  A particularly preferred class of dyes is that of formula <FORM:0840742/IV (c)/2> where Pz is the residue of an #s-substituted 1-phenyl-3-methyl-5-pyrazolone free from water-solubilising groups and R1 and R2 are alkyl-amino or aryl-amino groups together containing 6-12 C atoms.  When the residues R1 and R2 together contain more than 12 C atoms the dyes preferably have two water-solubilising groups.  Illustrative of specified 5-pyrazolones are 1-phenyl-3-methyl-5-pyrazolone-21- sulphonic acid, 1- (21, 51 dichlorophenyl)-3-methyl-5-pyrazolone-41-sulphonic acid, 3-methyl-5-pyrazolone, 1-(31-chlorophenyl)-3-methyl-5-pyrazolone and 1-(21-methyl-61-chlorophenyl)-3-methyl-5- pyrazolone. Illustrative of compounds from which R is derived are 1, 3-diaminobenzene and 1, 4-diamino-benzene-3-sulphonic acid. Examples of specified compounds from which R1 and R2 are derived are methyl- and butyl, amine, aniline, N-methylaniline, g -methoxypropylamine, diethanolamine, furfurylamine, cyclohexylamine, pyrrolidine and aniline-3-sulphonamide or -methybiulphane.  The dyes dye or print nitrogenous textile materials and superpoly-amide and -urethane fibres.  Neutral or weakly acid baths may be used.  Examples are given of the preparation of the dyes and their use in dyeing processes.  Yellow and greenish yellow shades are obtained.

Title: Volumetric respiration equipment notably for long-term servo-action anesthesia and reanimation
IPC: A61M16/00
Filed: 1976-01-19
Abstract: 1535277 Controlled frequency volumetric respirator R METIVIER 19 Jan 1976 [20 Jan 1975] 02022/76 Heading A5T Pharmaceutically operated respiratory apparatus for feeding air, oxygen or anesthetic to a patient comprises a breathing gas circuit and a control gas circuit, and is operable with a predetermined respiratory cycle frequency, insufflated volume per unit time, and inhalation/exhalation ratio. In one form of use, pressurized control gas at 120 gm/sq cm is fed either from compressor 1, or valve 2 connected to a pressure cylinder, to a first control valve 9 having a membrane 14 depressed by virtue of the attraction between adjustable magnet 15 and iron plate 30 such that valve member 11 is closed. The control gas therefore passes via line 5 to close valves 6, 7, and via line 33, needle valve 19, regulator 8 and constant flow line 17 to chamber 18c such that diaphragm 18a is caused to expel breathing gas or anesthetic from chamber 18b, via valve 21 to the patient P. During this time control gas bleeds via needle valve 16 to chamber 12 and ultimately overcomes the magnetic attraction between magnet 15 and plate 30. The membrane 14 thus moves up to close valve member 10 and open valve 11 to atmosphere. Valves 6, 7 thereby open and the pressure in chamber 18c is reduced to allow valve 20 to open and valve 21 to close. Breathing gas or anesthetic from bladder 22 thereby passes into chamber 18b for subsequent expulsion on the next cycle. Previously supplied breathing gas is exhaled via line 37, valves 23, 6 and filter 24 for subsequent return via line 39 with any oxygen or anesthetic introduced from rotameter 25. If the gas supply fails valve 26 opens to allow atmospheric air to be introduced. Once chamber 12 is drained via needle valve 16 the membrane is attracted towards the magnet again and the cycle is repeated. The circuitry includes a safety valve 27. The control gas may be supplied at a rate of 200 litres/min and a pressure of 120 gm/sq. cm. In a first modification, Fig. 2, the magnetic arrangement is replaced by a second membrane 14a which is acted upon by the pressure in line 28 and the needle valve 16a. The inhalation-exhalation times are determined by the surface area difference between membranes 14a, b. In a modified use of the apparatus the closed-circuit control fluid circuit is stopped and spontaneous respiration carried out. Atmospheric air may replace the oxygen/ anesthetic supply.
