Title: Purification of sulphur-containing gases and simultaneous recovery of sulphur
Inventor: HERBERT WILHELM
IPC: C01B17/04
Filed: 1969-01-21
Abstract: 1,249,563. Purification of sulphur-containing gases. METALLGESELLSCHAFT A.G. 21 Jan., 1969 [2 Feb., 1968], No. 3379/69. Heading C1A. An exhaust gas containing hydrogen sulphide and sulphur dioxide is purified and sulphur is recovered by adjusting the hydrogen sulphide to sulphur dioxide ratio to 2À5 : 1 to 4À0 : 1 and treating the gas in two successive stages which contain activated carbon, the temperature in the first stage being 120‹ to 200‹ C. and the reaction being 2H 2 S + SO 2  #  2H 2 O + 3S, and the temperature in the second stage being not in excess of 200‹ k., oxygen or air being added to the gas before the second stage, where the reaction 2H 2 S + O 2  # 2H 2 O + 2S takes place. The hydrogen sulphide to sulphur dioxide ratio may be adjusted in gases derived from the Claus process by a controlled supply of air to the furnace, by recycling part of the exhaust gas to the furnace or by adding hydrogen sulphide to the gas. Preferably the rate at which oxygen is added is about 1À5 times the rate which is stoichiometrically required. The temperature in the second stage may be kept at 200‹ C. or below by cooling a partial stream of purified gas and adding it to the gas before the second stage. Ammonia may also be supplied in addition to oxygen in the second stage. The activated carbon is regenerated by passing over it at 350‹ to 550‹ C. an inert gas which is free from oxygen, carbon dioxide and water. The regeneration may be preceded by purging with inert gas at 160‹ to 180‹ C. to remove carbon dioxide and water. Sulphur may be recovered from the desorption gas by subjecting it to heat exchange with superheated water at 120‹ to 130‹ C., and residual sulphur may be recovered by passing the gas through activated carbon which already contains sulphur.

Title: Improvements in and relating to electrical regulators for the automatic control of a variable condition or characteristic
IPC: G05D23/27
Filed: 1942-03-18
Abstract: 557,445. Automatic control systems for furnaces &c. BRITISH THOMSON-HOUSTON CO., Ltd. March 18, 1942, No. 3582. Convention date, March 20, 1941. [Class 38 (iv)] Temperature &c.-Anti-hunting means, in a system in which change in conductivity of a grid controlled valve indicates correction or departure of a variable condition from a desired value comprises a condenser in the grid circuit and switching means to initiate simultaneously the charging thereof whereby the conductivity of the valve may be restored in substantially the time taken in correcting a moderate departure. As an example, a photo-electric cell 13, responsive to the temperature of strip steel 10 issuing from a furnace 11 and controlling the speed of a motor 14 driving the strip, may be associated with an amplifying valve 20 to produce a current change, in a resistor 32 determining the relative potentials of cathode and grid in each of two valves 21, 22, when a departure from a desired strip temperature occurs. The values are arranged so that under correct conditions 21 is non-conducting and 22 conducting so that relay contacts 23a, 24a are both open. When a temperature rise increases the current through the amplifier, valve 21 becomes conducting, contact 23a closes and the speed of the motor 14 is increased. At the same time contact 23b connects a negative potention to one electrode of condenser 35 through a resistance 37 whereby a charge is built up which eventually restores the initial condition of conductivity of both valves. This operation may be arranged to match, in time, the cycle of the correcting process so that only a single correcting operation occurs upon a departure from the correct temperature.

Title: Improvements in or relating to the electrophoretic deposition of solids from dispersions, for example caoutchouc from latex
IPC: C08C1/14
Filed: 1929-02-05
Abstract: 305,630. Siemens - Elektro - Osmose Ges. Feb. 8, 1928, [Convention date]. Latex, treating.-In the electrophoretic deposition of substances from dispersions thereof, the dispersion is modified by the addition of suitable colloids or compounds comprising multivalent cathions in such a way that particles normally moving to the anode are directed to the cathode. The deposit may take place on the cathode or on a diaphragm or a moulded insulating body disposed in front of it. The reversal of direction is best effected in an electrolyte having a hydrogen ion concentration of 7 or less. When treating commercial rubber latex the ammonia is first partially removed. The reversal may be effected by adding 1 c.c. of a 5 per cent thorium nitrate solution to 36 c.c. of a dialyzed latex solution. Addition agents may be deposited with the rubber. In an example, 8 gms. of colloidal sulphur are stirred with water containing a protective colloid and the dispersion is introduced with stirring into 1 litre of dialyzed latex of 20 per cent caoutchouc content. The pH value is adjusted to about 7 and 28 c.c. of a 5 per cent solution of thorium nitrate is added. Zinc electrodes are employed in the electrophoresis. In another example, 4 gms. of zinc oxide and 6 gms. of sulphur are suspended in 40 c.c. of water containing a protective colloid such as gum arabic. The suspension is introduced with stirring into 1 litre of 20 per cent dialyzed latex and thorium nitrate added as before. Specification 301,100 is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a) a mixture of colloids may be separated by addition of a substance which effects reversal of direction for some of the constituents only. This subject-matter does not appear in the Specification as accepted.
