Patent GB-584613-A (GB)
Title: Improvements in or relating to the manufacture of sulphur-containing synthetic linear polyamides
IPC: C08G69/48
Filed: 1945-01-10
Abstract: N-Mercaptomethyl polyamides are manufactured by reacting an N-alkoxymethyl polyamide (prepared as described in Specification 573,482) or an N-methylol polyamide (prepared as in Specification 576,363) with thioacetic acid or thiourea and treating the resulting product with an alkali metal hydroxide.  The polyamide can be produced as the metal salt or free polyamide, either of which may be converted into the disulphide by mild oxidation, when cross-linking occurs between mercaptomethyl groups; the disulphide can be reduced to the soluble thiol derivative by ethyl thioglycollate, thiosorbitol or hydrogen sulphide.  The reaction is carried out in the presence of alcohols or mixtures of alcohols with chloroform or aromatic hydrocarbons.  In carrying out the process, an alcoholic solution of an N-alkoxymethyl polyamide and thiourea, with the addition of a mineral acid is treated with an alkali metal hydroxide in alcoholic solution, to give the corresponding N-mercaptomethyl polyamide, or the metal salt if excess alkali is used.  Clear rubbery films are obtained by coagulating a solution of the N-mercaptomethyl polyamide with an aqueous solution of a salt, e.g. sodium sulphate, to which a small amount of oxidising agent, e.g. hydrogen peroxide, has been added followed by treatment with dilute acetic acid and washing with water.  The lead salt, owing to its limited solubility, can be used as a means for purification.  Thio acetic acid yields a product having extralinear acetylthio methyl groups attached to the nitrogen atoms, mercaptomethyl groups being formed on treatment with an alkali metal hydroxide.  Specifications 461,236 and 461,237 also are referred to.  In the Specification as open to inspection under Sect. 91, any suitable sulphur-containing compound, such as thiourea, is reacted with the N-alkoxoxymethyl polyamide or N-methylolpolyamide and the resulting product treated with an alkali, such as an alkali metal hydroxide.  This subject-matter does not appear in the Specification as accepted.

Convention date, Feb. 7,1929. [Class 51 (ii)]. A roller-way leer for annealing sheet glass is constructed to provide for a dissipation of heat in such a manner that a uniform temperature of the sheet in a plane transverse to the direction of travel is first obtained, this equalized temperature being maintained until the cooling of the sheet is completed. As shown, at the entrance end of the leer, roof lagging e<1> is provided at the sides only, while below the floor j are arranged channels m<1>, m<2>, m<3>, separated by walls k, the side channels being provided with a greater thickness of lagging m than the middle one. The thickness of the lagging e<1>, m is progressively reduced towards the discharge end of the leer, the rate of reduction being less in the parts adjacent the edges of the sheet, and the rate of reduction of the floor lagging m being less than that of the roof lagging el. The side walls l of the leer also diminish in thickness towards the discharge end. The central unlagged part of the leer roof at the entrance end is in the form of a re-entrant channel h, the upper side of which is provided with movable panels i for controlling the contact of the exterior atmosphere with the depressed part of the channel. The difference in height between the central and side portions k, e is gradually decreased until at or about the plane E, F, Fig. 1, the leer has an unlagged flat brickwork roof e, Fig. 5. This is succeeded by a roof section of corrugated sheet metal f, while the final zone of the leer is constituted by cooling pipes p, p<1> which are connected to supply and discharge headers q, q<1>, r, r<1> and are each fitted with a valve s, s<1>. Burner openings v are provided in the entrance zone so that heat may be supplied to the edges of the sheet if necessary.
