Patent GB-330821-A (GB)
Title: Method and apparatus for preparing gases by the interaction of solids and liquids
IPC: C10H15/02
Filed: 1929-08-08
Abstract: 330,821. Autogenwerk Sirius Ges. Feb. 22, 1929, [Convention date]. Gases, apparatus for producing by wet methods. -In generating acetylene and other gases bv the interaction of pulverulent material with liquid, the material is compressed on its way from a container to the generator, and then introduced into the generator below the surface of the liquid, the compressed material preventing both the ingress of air to the generator and also the passage of gas from the generator to the container. As shown in Fig. 1, a tube 2 supplying carbide dust from a container to a generator 1 extends into the generator below the surface of the water. At the lower end of the tube 2 is arranged a base 3 controlled by a lever 6 which is pivoted at 4 and weighted at 5. The dust in the tube 2 is compressed against the base 3 by an inclined vane 8 mounted on a shaft 7, whereby the interstitial air is forced out rearwardly, and the passage of acetylene up the tube 2 is prevented. The resistance of the base 3 is eventually overcome, and carbide drops into the water, a sieve 9 preventing it from rising to the surface. Modified forms of apparatus are described in which the base 3 is replaced by a spring-pressed conical base and by two adjacent bases each controlled by a loaded lever; in the latter form the carbide is compressed by a piston. Fig. 4 shows a further modification in which a base for the supply tube 2 is dispensed with, the tube being so constructed that its frictional resistance enables the necessary compression to be obtained.

Title: Process for determining the concentration of hydrogen ions
IPC: G01N31/16
Filed: 1933-09-02
Abstract: <PICT:0429906/III/1> <PICT:0429906/III/2> The hydrogen ion concentration of a substance is determined by comparing it electrometrically or colorimetrically with a solution of known hydrogen ion concentration, and titrating the latter solution with alkali until it corresponds to the liquid under test.  Suitable apparatus is shown in Fig. 2 in which the electrode vessels 1, 2 contain respectively the liquid to be tested and the standard liquid and are connected by a potassium chloride-agar syphon 3.  The electrodes 4, 5 are connected to the capillary electrometer 9.  The titrating liquid is contained in the burette 10, which may be calibrated to give direct readings of the hydrogen ion concentration. Capillary electrometers for use in the process may be constructed as shown in Fig. 5.  The bulb 21 and the inclined tube 23 contain mercury constituting the electrodes separated by sulphuric acid in the capillary tube 22.  To expose a clean mercury surface the instrument is inclined downwards on the side at which the tube 23 is fitted and is then restored to its normal position.

Phosphorus, stated to inhibit oxygen migration is distributed in the anodic oxide layer forming the dielectric of a capacitor substantially uniformly or in relatively greater concentration in the region adjacent to the anode. The electrical properties of such a capacitor are less sensitive to heat treatment. The electrolytic capacitor shown is manufactured by impregnating the porous niobium, tantalum, titanium or zirconium pellet 11 with phosphorus, e.g. by heating it in a sealed evacuated tube containing red phosphorus, or by cathodic sputtering in a phosphorus-containing atmosphere. The pellet is anodized, e.g. in 0À1% H 2 SO 4  to form an oxide layer 12 having phosphorus distributed therein and the semiconductive layer 13 is manganese or lead dioxide formed by pyrolysis of a suitable precursor. An optional contact layer 14 of e.g. graphite may be applied before one contact electrode 15 of e.g. silver. Liquid electrolytes may alternatively be employed.

The interaction of the main fluid stream and the emitted fluid stream restricts the outflow of the former and so increases the dwell time of the main fluid within the shaft. The increase in dwell time results in a greater decomposition of the impurities contained in the mainstream. Figs. 2-8 and 11-12, not shown, depict various modifications of the above embodiment in which, inter alia the annular chamber is shown disposed intermediate the incinerator shaft ends. Figs. 13- 14, not shown, depict the apparatus used in the pyro-decomposition.

Abstract: 505,752. Electrophoretic treatment of colloidal dispersions. SEMPERIT OESTERREICHISCH - AMERIKANISCHE GUMMIWERKE AKT.-GES. Sept. 13, 1937, No. 24909. Convention date, Sept. 12, 1936. [Class 41] In a process for purifying, separating or concentrating colloidal dispersions by subjecting them between diaphragms to an electric field under such conditions that separation into horizontal layers occurs, the separation &c. is accelerated by introduction of one or more additional diaphragms between those separating off the electrode spaces. In the apparatus shown the space between the main diaphragms 4, 5 is divided by diaphragms 6 of cellulose hydrate or parchment into spaces which are in communication at the top and bottom. Fresh dispersion is admitted to the spaces by lateral inlet pipes 7. The total electric resistance of the diaphragms should be not greater than that of the dispersion. The individual intermediate diaphragms may be replaced by a single undulated diaphragm. Stratification is promoted by a low concentration of dispersion, by a low potential gradient or by periodical reversal of current. The dispersions are preferably first freed from electrolytes as far as possible e.g. by dialysis. Dispersions of pectin, gelatin, casein, dyestuffs, metal sols or of indiarubber may be treated. Specifications 492,030 and 505,753 are referred to.

Title: Process for the production of hydrogen and carbon disulphide
IPC: C01B3/34
Filed: 1961-07-11
Abstract: Carbon particles maintained electrically at above 1300 DEG  C. are fluidized by the passage of a gas containing methane, whence C is deposited on the particles of the bed and hydrogen is recovered. The resulting carbon particles maintained electrically at 700-1500 DEG C. are then fluidized by the passage of a gas containing elemental sulphur vapour.  The methane feed gas, e.g. natural gas, may be passed through a vertically mounted cylindrical reactor, of e.g. a high-temperature resistant glass, containing previously calcined and screened petroleum coke particles, the overflow coke being subsequently bled off.  Carbon disulphide is produced by subsequently passing a stream of sulphur vapour at 900-1200 DEG  C. through the bed.  The reaction may be carried out in separate zones, the excess of carbon produced in one zone by decomposition of CH4 being transferred to the other for reaction with S, or, alternatively, by a discontinuous process in the same zone whereby CH4 is decomposed to deposit C, and S is then passed through the bed to remove an amount of C equivalent to that deposited on the particles of the bed by the CH4.  In the separate zone process a supplemental supply of C may be added to the second zone or excess C from the first zone may be removed entirely from the two-zone system. Specification 833,562 is referred to.  Reference has been directed by the Comptroller to Specification 833,562.
