Abstract: 364,252. Exhaust silencers. COULTHARD, T., Marsh Mills, Plympton, Devon. Nov. 14, 1930, Nos. 34284 and 37205. [Class 7 (ii).] Exhaust gases entering a container a by a pipe c impinge on a conical or paraboloidal end h of an otherwise cylindrical hollow member g, and are deflected on to the wall of the container whereby cooling is facilitated. The annular space between the container a and member g is subdivided by straight or helical vanes i secured to member g. The gases flow through this annular space to the rear end of the silencer and reach the outlet pipe f through perforations m at alternate ends of a number of coaxial tubes l. The inner end of the pipe f, which is also perforated, is sealed by a plug v which fits into the end h. Flanges d and stiffening plates e secure the inlet and outlet pipes to the endplates b. In a modified construction, the wall of the container a is corrugated. In a further modification, Fig. 4, the container is divided into two parts a<1> connected by circumferential tubes t, the interior of member g being open to atmosphere. Around the tube l a number of baffles o with radiating fingers r are secured by means of flanges s, the fingers of adjacent baffles being staggered. These baffles are also applied, in a still further modification to the construction shown in Fig. 1.

Title: Improvements in and relating to the deaeration and degasifying of water and other liquids
IPC: B01D19/00
Filed: 1921-12-23
Abstract: 199,748. Morison. Dec. 23, 1921. Feed-water, supplying.-For the removal of dissolved gases from boiler feed-water, the latter, while in continuous flow and as an unbroken stream, is repeatedly raised to and maintained at boiling temperature at any pressure, by the repeated applications of heat; thus, the water is passed through a single de-aerating vessel or a series of de-aerating vessels, and while passing therethrough is heated repeatedly and boiled, as by steam jets or nozzles, at different points in the dire of flow. The boiling at the several stages may be at atmosphere pressure, or at pressures above or below atmospheric, and the pressure may vary from stage to stage. Between each of the stages the water may be cooled by introducing cooling coils into the circuit. The heated water leaving the de-aerating apparatus may be passed through an interchanger receiving the water to be treated, which is thereby heated, while the discharged de-aerated water being at a lower temperature can more economically absorb waste or low-grade heat. When an evaporator is employed for making up loss of feed-water, the steam so generated may be used for de-aeration, the absolute pressure in the de-aerator being adjusted so that the amount of steam available is sufficient to effect the boiling. The de-aerating apparatus may be combined with the condenser system, in which case the condensate flows by gravity through a water seal or is passed by a pump 28, Fig. 8, from the condenser 26 to the de-aerating vessels 2, 3 in succession; these are provided with heating jets 9 and with connections to the vacuum space of the condenser, the sections being placed under the same pressure or under increasing pressures by means of differentially-loaded valves 27. the latter section being in the second case placed at a lower level in order to ensure a flow of water; a second pump withdraws the water from the de-aerating apparatus and discharges it to the boiler. Specifications 173,301, [Class 46, Filtering &c.] and 183,534, [Class 1 (i), Chemical processes &c.], are referred to. The Provisional Specifications include modifications of the methods and arrangements described above in which the de-aeration is effected by heating, but not necessarily by a pro. cess involving repeated boiling.

Title: Process for the production of heavy metal-containing azo dyestuffs and their use
IPC: C09B43/44
Filed: 1960-10-11
Abstract: A process for the production of chromium- or cobalt-containing azo dyestuffs is characterized by diazotizing an amine of the general formula <FORM:0955506/C3/1> where A represents a radical of the benzene series free from water solubilizing groups, Acyl1 and Acyl2 represent acyl radicals derived from organic sulphonic acids or from sulphamic acids of secondary amines and in which formula the amino group and the amido group are in o-position to each other, coupling the diazonium compound with a coupling component which couples in an adjacent position to a phenolic or enolic hydroxy group or a primary or secondary amino group, then saponifying one acyl radical of the diacylamido group in the coupling product in an alkaline medium and treating the reaction product with an agent introducing chromium or cobalt, the components being so chosen that there are no salt-forming substituents which dissociate acid in water in the end product.  The acyl groups in the above compounds are preferably derived from aliphatic sulphonic acids having at most 5 carbon atoms or from benzene sulphonic acids containing as nuclear substituents methyl sulphonyl or ethyl sulphonyl groups.  Acyl radicals derived from sulphamic acids specified include dimethylamino, piperidino and morpholino sulphonyl radicals.  Among the many products of which the preparation is described are the chromium complex of the dye obtained from N-di(methylsulphonyl)-amino-2-aminobenzene and 1-carbomethoxy - 7 - hydroxynaphthalene, acetoacetic acid-3-chloranilide and 1-(3-chlorophenyl)-3-methyl-5-pyrazolone and the cobalt complex of the dye obtained from N-di-(31-methyl-sulphonylbenzenesulphonyl) - amino - 2 - aminobenzene and 3,4-dimethyl-1-hydroxybenzene. The dyes are used for colouring synthetic and natural polyamides, e.g. wool.
