Patent GB-352424-A (GB)
Title: Process of producing hydrogen and ammonium phosphates
IPC: C01B25/28
Filed: 1929-12-30
Abstract: Ammonium phosphate and hydrogen are made by reacting liquid water, phosphorus, and ammonia under pressure and at temperatures above 100 DEG  C. in the presence of a metal of the iron group or a salt thereof.  A high temperature, e.g. about 350 DEG  C. at a pressure of about 250 atmospheres, gives good results.  In the presence of an excess of ammonia and water, the catalyst is unattacked, so that the reaction vessel may consist wholly or to a large extent of said catalyst, e.g. steel.  The reagents may be introduced separately, or two in admixture, thus molten phosphorus and ammonia solution, or an emulsion of phosphorus in water and ammonia gas may be separately added, or an emulsion of phosphorus in ammoniacal water may be used. The reaction products are used to preheat the reacting substances. The hydrogen evolved is washed with water to recover its ammonia content for re-use, and after additional purification, if necessary, may be used for the synthesis of ammonia which can be employed in the process and for neutralizing the acid ammonium phosphate produced. The ammonium phosphate solution may be concentrated by reducing its pressure and by additional heating, the slightly alkaline steam evolved being used, after condensation, in the process, together with the mother liquors after crystallization of ammonium phosphate.

Title: Improvements in and relating to the sulphuric acid contact process
IPC: C01B17/765
Filed: 1965-09-17
Abstract: A contact process for sulphuric acid manufacture, wherein, in a multi-stage catalytic oxidation of a gas containing sulphur dioxide with a plurality of sulphur trioxide absorption stages, the residual gas from a first sulphur trioxide absorption stage is partially re-heated by heat exchange with a hot gas occurring in the process, to a temperature supporting the combustion of sulphur in the residual gas, and liquid or finely divided solid pure dry sulphur is introduced into the gas, which, if necessary is supplemented with combustion air dried with sulphuric acid, the conditions being such that the resulting gas is brought to the initial temperature necessary in the final contact stage. In the flow diagram, purified and dried pyrites roasting gas is passed through heat exchangers 9 and 10 into a contact apparatus 11.  In the heat exchangers the reaction gas from the contact layers 11a, 11b and 11c gives up heat to the roasting gas in order to heat the same to the initial temperature of the layer 11a.  After this layer, cold roasting gas is admixed for temperature regulation. After the second layer 11b, the gas passes through heat exchanger 10 into the third layer 11c.  The gas leaves the contact apparatus through the heat exchanger 9 and passes into a first SO3-absorber 12. <PICT:1119672/C1/1> The gas derived from this operation is mixed with dry air and heated in a heat exchanger 13 to 250 DEG  to 300 DEG  C. or above such that after addition of sulphur in a mixing chamber 15, the oxidation remains in operation in the contact layer 11d.  After cooling in the heat exchanger 13, the reaction gas passes through a second absorber 14 and leaves the latter practically free from SO3.  Direct cooling can be employed in the present process by blowing dry air between the contact layers.

Title: Improvements in process of tempering nylon strands
IPC: C08L77/00
Filed: 1959-11-27
Abstract: 893,386. Tempering nylon strands. UNITED STATES RUBBER CO. Nov. 27, 1959 [Dec. 29, 1958], No. 40330/59. Drawings to Specification. Class 2(2) [Also in Group IX] Polyamide strands are tempered by subjecting them under sufficient tension to prevent them from shrinking, and so that their length is maintained substantially constant, to a temperature not exceeding 7‹F. above and not more than 80‹F. below their melting point, for a period of at least 7 minutes and under conditions such that oxidation of the polyamide is substantially prevented either by carrying out the heat treatment in an atmosphere free from air or by the use of polyamide strands containing a small proportion of an anti-oxidant. The melting point of a strand is determined when it is free from tension and when the strand is in air at normal atmospheric pressure. It may be determined by gradually raising the temperature of a hot plate on which the strand has been placed and observing the liquefaction of the strand under a microscope. The melting point is very sharp. A tension of about ¢ to 3 gm./denier is preferably imposed on the strands during the treatment. The treatment may be carried out in a vacuum or in an inert gas such as steam or nitrogen. Alternatively the treatment may be carried out in air using strands containing a rubber antioxidant such as phenyl beta or alpha naphthylamine, N,N<SP>1</SP>-diphenyl-p-phenylene diamine, a 9,9-dialkyl acridan or phenothiazine. The heat treatment may be conducted for a period of 7 to about 30 minutes. The tempered strands are evaluated in a testing machine which simulates service conditions under which the strands are used in tyre manufacture (see Group IX). Nylon cords made from strands treated according to the invention have reduced tendency to creep under stress, reduce "flat spotting" in tyres and have reduced shrinkage when subjected to tyre curing conditions.
