Abstract: 774,200. Rectifying. LICENTIA PATENTVERWALTUNGS-GES. July 8, 1954 [July 9, 1953], No. 20005/54. Class 38 (2). In a contact rectifier having two or more parallel connected contacts 4, 5 associated with each main switching choke 1, a subsidiary switching choke 8, 9 is connected in series with each set of contacts, and produces a current step, preferably of the same order of magnitude as that produced by the main reactor. These subsidiary switching chokes prevent currents of reverse direction and equal magnitude from flowing in the contacts at the instant of contact opening during the step when the total current is held to zero by the switching choke. The contacts 4, 5 are shunted by rectifiers or condensers 10 connected at one end to the mid point of impedances 11, 12 connected between the junctions of the auxiliary switch chokes 8, 9 and the contacts 4, 5. The impedances 11, 12 may be resistive, capacitative, inductive or mixed. The auxiliary chokes may comprise rings of saturable iron carrying premagnetizing windings and be slipped over the leads to the contacts which are kept close together to reduce the inductance of the loop including the contacts. Magnetic cores with air gaps may also surround the conductors to maintain equality of current division between the contacts.

Patent GB-805744-A (GB)
Title: Process for the production of acrylonitrile
Filed: 1956-06-29
Abstract: Accumulation of carbon dioxide and nitrogen formed as secondary products in the continuous production of acrylonitrile from acetylene and HCN in the presence of acid cuprous chloride at elevated temperatures with recycling of unchanged acetylene is prevented by removing these gases from the circulating gas.  The reaction gas leaving the reaction tower may be washed in the usual way to remove acrylonitrile, HCN, acetaldehyde, &c., and then freed from CO2 by washing with aqueous alkali and the nitrogen removed by washing the circulating gas with water whereupon the acetylene dissolves and the residual undissolved nitrogen may be removed from the system and the acetylene recovered and recycled.  The wash water saturated with acetylene is advantageously used for washing the gases leaving the reaction tower.  It is preferred to treat only part of the circulating gas, the proportion depending on the amount of CO2 and N2 in the gas.  The purified gas is returned to the reaction tower again after the acetylene consumed has been replaced.  In an example acetylene and HCN are reacted and the efficiency of acrylonitrile formation decreases when the circulating gases are not treated by the process of the invention; when 3 per cent of the circulating gas is passed through the nitrogen washing system the efficiency is partially restored and when in addition 10 per cent is passed through the alkali liquor washing system to remove CO2, efficiency is restored to the initial value. Specification 691,248 is referred to.

Title: Improved process for the manufacture of artificial silk
IPC: D01F2/06
Filed: 1931-07-14
Abstract: Artificial silk having filaments of from 6 to less than 1 denier are produced by spinning in the normal manner by means of acid salt baths, a normally ripened viscose having a low cellulose content (not higher than 6 per cent), to which an excess of carbon disulphide has been added or which has been prepared by the application of an excess of carbon disulphide.  The normal amount of carbon disulphide is regarded as 45 per cent of the weight of the cellulose, and it is now proposed to use an excess amounting, for example, to from 9 to 18 per cent of the weight of the cellulose, but a still larger excess may be used by lowering the cellulose content of the solution.  In examples, (1) to 1000 parts of viscose made in the normal manner and diluted to a cellulose content of 5,7 per cent, there is added 7 parts of carbon disulphide.  The product is ripened and spun in the usual way; (2) normal viscose is diluted with caustic soda lye so as to contain 4,1 per cent of cellulose and 5,5 per cent of caustic soda, mixed with 1,7 per cent of carbon disulphide, ripened, and spun in the usual way; (3) a viscose is prepared in the normal manner, but during the sulphidation or during solution, an excess of about 18 per cent of carbon disulphide is added, and the product, which contains 5,0 per cent of cellulose and 5,2 per cent of caustic soda is ripened and spun into the usual spinning bath.  Specifications 15752/10, 135,205, 189,973, 212,865, 220,934, 253,953, 314,504, 319,243, [all in Class 2 (ii), Cellulose &c.], and 350,397 are referred to.
