Abstract: <PICT:0710713/IV(c)/1> In apparatus for dyeing fabrics a continuous supply of gas bubbles is formed in the dyeing liquid while vibrations of sonic frequency are imparted by electromagnetic means to a body immersed in the liquid.  In an example the invention is applied to the machine described in Specification 680,418, which comprises a hollow rigid body 1 connected by a tube 2 with the armature 3 of an electro magnet.  The tube 2 is supported by and secured to two diaphragms 7, 8 attached to a housing 6 for the electromagnet.  An intermediate wall 25 is formed with one or more apertures 26 which are overlapped by a flexible rubber disc 27 so as to form a valve. As the diaphragm 8 vibrates air is sucked into the housing 6 through inlet openings 29 and out through one or more openings 30 in the tube 2 and into the liquid through an outlet 31.  In an alternative form, air or other gas may be passed into the liquid by means of a separate pump, or by using a source of gas under pressure.  An inert gas may also be used.  Alternatively gas-generating substances may be added to the liquid e.g. mixture of an alkali metal carbonate such as powdered sodium bicarbonate and tartaric acid, or sodium carbonate or potassium carbonate and tartaric acid.

Abstract: 1299078 Esters IMPERIAL CHEMICAL INDUSTRIES Ltd 13 April 1970 [30 April 1969] 22084/69 Heading C2C Esters of orthophthalic acid are produced by heating the acid, or phthalic anhydride, with a C 4  to C 14  alkanol, removing water-vapour from the reaction mixture and, at least during the later stages of the reaction, withdrawing part of the reaction mixture and introducing it in the form of a spray of small droplets to the vapour space above the reaction mixture. The hourly circulation rate is preferably 4 to 10 times the volume of the reaction mixture. The liquid which is withdrawn may be heated to a temperature 50‹ C. higher than the temperature of the bulk of the reaction mixture. An example relates to the production of dioctyl phthalate by heating phthalic anhydride with excess iso-octanol and a catalytic amount of sulphuric acid in a lead-lined distillation pot enclosed by a steam jacket. Towards the end of the esterification, when the temperature is 145‹ C. and nearly all the reaction-water has been distilled off by azeotropic distillation with refluxing iso-octanol, the circulation pump is started and batch distillation is carried out to remove the last traces of water.

Aug. 8, 1932, No. 22222. Convention date, Sept. 2, 1931. [Class 39 (i).] A vapour stream is produced from a mercury pool other than the cathode to oppose the vapour stream from the cathode. A watercooled tank 1, Fig. 1, is fitted with a plate 2 carrying an annular cathode 5 which is connected by a duct 7 to the auxiliary pool 6. Anodes 10 are grouped within a shield 12 which is divided into sectors by partitions 16. The distance between the anodes and the partitions 16, which are at cathode potential, is made sufficiently small to prevent an arc therebetween. A shield 20 protects the exposed portion of the cathode plate. Ionized vapour and foreign gases in the anode chamber are swept into an annular condensing chamber 36 by vapour which is guided from the pool by shields 12, 18, 31. Maintaining anodes 35 are provided to prevent undue extension of the arc paths, and the partitions 16 may be extended across the tank into the condensing chamber 36 to separate the maintaining anodes. A cooling ring 26 is provided. The pool 6 is heated by an element 30 and the generation of vapour may be controlled by connecting the heater in series with the anodes through a transformer or in series with the load: In a modification, Fig. 3 (not shown), a quartz cylinder subdivides a mercury pool to form the auxiliary pool and the annular cathode. In a further modification, rows of anodes 10, Fig. 4, are mounted at the sides of a rectangular rectifier and are protected by shields 40. Two auxiliary pools 45 and a central condensing chamber having cooling members 41 are provided.

Title: Improvements in gas flow calibrator
IPC: G01M3/20
Filed: 1958-07-11
Abstract: <PICT:0833913/III/1> An apparatus for calibrating gas detectors of the type used to detect leaks of organic halogenated compounds, consists of a capillary tube discharging into a conduit, means to supply the vapour of a halogenated organic compound at a measured rate to the capillary at constant pressure and also purified air to the conduit; the air halogen-containing gas mixture being discharged to a receptacle adapted to receive the probe of the leak detector under test.  The reading with the gas under test is then compared with the pre-recorded reading of a standard removable capillary tube inserted in the receptacle, by which the pressure gauge measuring the flow of the halogenated gas is calibrated.  An electric vibrator pump 1, Fig. 2, supplies air to a filter 5 containing charcoal and to a divided tube 9, part of the air flowing to a selector valve 10 and part to the standard gas leak assembly 12.  The halogenated test gas is stored in a tank 19, which leads through a shut-off valve 21 and control valve 23 to a pressure chamber 25 having a ballast tank 35. By manipulating valves 21, 23, and a decrease valve 30, a static pressure is maintained in the ballast tank 35, and recorded on the gauge 26. The selector valve 10 may be turned to zero calibrating position, when purified air only is supplied to the discharge 43 in which the probe 44 of the gas detector 45 is inserted, and is then turned to allow the flow of air and measured amount of halogenated vapour to the receptacle.  The removable standard capillary tube (not shown) comprises a graduated tube containing a short column of coloured liquid as indicator, and by the readings obtained, the gauge 26 is calibrated, an outer scale showing the weight flow of gases at various pressures indicated on the inner scale.
