Title: Cellulose solutions and process for their production
IPC: D01F2/28
Filed: 1923-06-29
Abstract: Cellulose solutions are prepared by treating cellulose or a cellulose conversion product with a strong organic base, for example, a quaternary ammonium base or a base in the aqueous solution of which a highly electrolytically-dissociated hydroxide may be assumed to be present, in the presence or absence of caustic alkali. Suitable bases are tetra-ethyl ammonium hydroxide, tetra-methyl ammonium hydroxide, and phenyl trimethyl ammonium hydroxide. The reaction may be carried out in aqueous solution and at a room temperature or lower, for instance, below 0 DEG C., depending on the character of the original cellulosic material and on the presence or absence of alkali, the temperature being lowered by stages until solution occurs. The initial cellulose material may be bleached or unbleached cellulose products obtained by mechanical comminution of cellulose in the presence of water; products obtained by treating cellulose with oxidizing or reducing agents with or without a preliminary treatment with alkalies, acids, salts, etc.; products obtained by heating cellulose alone or in the presence of water or glycerine; products obtained by treating cellulose with hot or cold alkalies alone or in the presence of salts, with or without subsequent treatment with dilute acid and with or without previous or subsequent or simultaneous treatment with bleaching or oxidizing agents; products separated from solutions of cellulose, cellulose hydrate or hydrocellulose in ammoniacal copper oxide &c., zinc halides, or strong mineral acids such as sulphuric, phosphoric, arsenic or hydrochloric acid, or from viscose solutions; artificial silk, artificial cotton, staple fibre, etc.; products obtained by treating cellulose or its conversion products with these solvents to a point short of dissolution; hydrocelluloses such as are obtained by treating cellulose with dilute acids at ordinary or raised temperature, or by drying in the presence of acids, or by employing strong sulphuric acid at temperatures below 0 DEG C., gaseous hydrochloric acid, or chlorine; oxycelluloses; products obtained by denitrating, saponifying, &c. cellulose esters; the alkali-soluble derivatives of Specification 177,810. The solutions are coagulated by acids, salts, alcohols, water, steam, heat, etc.; and they may be worked up into artificial silk &c., films, artificial hair, plastic masses, coatings, finishings, fillings, sizes, artificial leather, &c. In examples, the starting material is treated with an aqueous or alkaline solution of tetra-ethyl or methyl ammonium hydroxide or phenylmethylammonium hydroxide, and the mixture cooled to \sw8 DEG to \sw11 DEG  C.

Title: Method and apparatus for the control of a process for the recovery of sulphur
IPC: G05D11/00
Filed: 1971-05-25
Abstract: 1343474 Recovery of sulphur SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 25 May 1971 [27 May 1970] 16966/71 Heading C1A Sulphur is produced by the reaction of H 2 S with an SO 2 -containing gas which derives from the regeneration with a reducing gas (e.g. H 2  or CO) of a solid acceptor (e.g. CuO) that has become loaded with sulphur oxides by removing these from gases, e.g. waste gases. In the method, the difference between a signal F, (corresponding to the magnitude of the reducing gas stream) and a signal F 2  (corresponding to the magnitude of the stream from the regeneration) is used to set the desired composition of the gas mixture of H 2 S and SO 2  for the sulphur recovery. The difference (F 2 -F 1 ) may be used to control the rate of H 2 S fed to react with the SO 2  to form sulphur using the system shown in the Figure. A regeneration gas 3 measured by flowmeter 8 to give F 1  is fed to the SO 2 -acceptor 1 from which flows a gas stream containing SO 2  4 measured by flowmeter 9 to give signal F 2 . A subtracting element 10 gives F 2 -F 1 . The flowmeter 11 measures the stream of H 2 S containing gas 5 and passes its signal to controller 12 which operates valve 13 in the gas stream 5 and which is determined by the output of 10, i.e. F 2 -F 1  so that the gas mixture in a reactor 2 always has the composition required for the sulphur recovery. Modifications include (a) the partial oxidation of the H 2 S stream to give a mixture of H 2 S and SO 2 , (F 2 -F 1 ) being used to determine the feed of O 2  or O 2  containing gas to the H 2 S, (b) the division of the H 2 S into 2 streams p and q, q being fed directly to react with SO 2  while p is subjected to partial oxidation to form SO 2  which may be combined with the SO 2  from the regenerator and (F 2 -F 1 ) is used to control the magnitude of q or the supply of oxygen to the stream p

Filed: 1947-06-28
Abstract: 627,153. Linear - dimension gauges. HARTLEY, A. J. June 28, 1947, No. 17097. [Class 106 (ii)] [Also in Group XXIII] A tool for gauging, measuring or marking off the depth and width of key-ways in shafts and bores comprises a body member having an edge curved to coincide with the curvature of the shaft or bore on which or in which it is to be used, and a gauge member of the width of the required key-way projecting from the said curved edge to the extent of the depth of the required key-way. A flat body member 10 has a straight edge 11 and an edge 12 curved concavely or convexly to fit a shaft or bore. A gauge member 16 is located in a groove 15 with ledges at each side and is secured by a bolt or set pin 17 whose head may be extended to form a handle 18, one handle being adapted for use with several such tools. Grooves 19 in the curved edge 12 allow for the feather liable to be formed during cutting of the keyway. One end of the gauge member 16 may be reduced as at 20 and when reversed may be used to gauge the depth before the full width is cut, the correct depth being indicated when the opposite end of the member 16 is flush with the straight edge 11. The gauge member 16 may be slotted for co-operation with the pin 17 either to allow for an adjustment in depth of key-way required or to allow the two ends to be used as " go " and " no go " gauges for the width of key-way by allowing the ends to project beyond the curved edge or straight edge, thus avoiding reversing the gauge member.
