Title: Improvements in or relating to substituted thiobarbituric acids and their salts and process of preparing the same
Filed: 1953-03-18
Abstract: The invention comprises thiobarbituric acids of the formula <FORM:0720826/IV (b)/1> wherein R represents an ethyl or allyl radical and R1 represents a 1-ethylpropyl or 1-methylbutyl radical, and their pharmaceutically useful salts.  These salts include, for example, those of the alkali metals (e.g. sodium and potassium), alkaline earth metals (e.g. calcium), and substituted ammonium radicals (e.g. ethanolamine, ethylene-diamine and tetra-alkyl ammonium hydroxide).  The thiobarbituric acids are prepared by condensing, in the presence of an alkaline catalyst (e.g. sodium in absolute alcohol), N-methylthiourea with an ester or diester of a compound of formula <FORM:0720826/IV (b)/2> wherein Y represents a carboxyl or a cyano group; and hydrolysing the reaction product in the case where Y is a cyano group to remove the imino group which is first formed.  Suitable esters and diesters for use as starting materials are the ethyl esters of ethyl-(1-methylbutyl)-cyanoacetic acid, ethyl-(1-ethylpropyl)-cyanoacetic acid, allyl - (1 - methylbutyl) - cyano - acetic acid, allyl - (1 - ethylpropyl) - cyano - acetic acid and ethyl -(1 - methylbutyl) - malonic acid.  The examples describe the preparation of 1-methyl-5-ethyl-5-(11-methylbutyl) - 2 - thiobarbituric acid and the sodium salt thereof, 1 - methyl - 5 - ethyl - 5 - (11 - ethylpropyl) - 2 - thiobarbituric acid, 1 - methyl - 5 - allyl - 5 - (11 - methylbutyl) - 2 - thiobarbituric acid and the potassium salt thereof, and p  1-methyl-5-allyl-5-(11-ethylpropyl)-2-thiobarbituric acid.  Imino - 2 - thiobarbituric acids are formed when N-methylthiourea is condensed with cyanoacetic esters.  The following are prepared as intermediates: 1-methyl-5-ethyl-5-(1-methylbutyl) - 4 - imino - 2 - thiobarbituric acid, 1 - methyl - 5 - ethyl - 5 - (1 - ethylpropyl) - 4 - imino - 2 - thiobarbituric acid, 1 - methyl - 5 - allyl - 5 - (11 - methylbutyl) - 4 - imino - 2 - thiobarbituric acid and 1 - methyl - 5 - allyl - 5 - (11 - ethylpropyl) - 4 - imino - 2 - thio - barbituric acid. Specifications 613,704 and 613,705 are referred to.

Title: Improved process for concentrating volatile aliphatic acids
IPC: C07C51/44
Filed: 1927-03-18
Abstract: 271,044. Holzverkohlungs Industrie Akt.-Ges. May 17, 1926, [Convention date]. Acids, concentrating and distilling. - In the concentration of volatile aliphatic acids such as acetic acid or propionic acid by distillation in the presence of alkali bisulphate or other water combining substances, the vapour mixtures passing off during the distillation are brought into contact with sodium bisulphate or salt mixtures containing this; the dilute acid may be treated with water combining substances before distillation. For example, 100 parts of 10 per cent acetic acid are treated with 200 parts sodium bisulphate and distilled, and the distillation vapours are passed throuah a column charged with granular sodium bisulphate, the acid from the column having a concentration of 80-90 per cent. The process is particularly suitable for the concentration of impure dilute solutions such as pyroligneous acid; the raw acid is first treated with sodium bisulphate to enable the oily and tarry constituents to be separated in known manner, and the vapours passing off during the subsequent distillation are brought into contact with sodium bisulphate. The small quantity of acid remaining m the dilute solution may be recovered by esterification. Specification 28595/02, [Class 2, Acids and salts, Organic &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also states that the concentration of the dilute acid may be effected by adding to the dilute acid before distillation water combining substances such as sulphuric acid, or salts thereof, e.g. sodium bisulphate, or mixtures of salts, or mixtures of acids and salts, and then subjecting the mixture to distillation, or the dilute acid may be distilled and the vapour mixtures brought into contact with such substances, or both methods may be employed in combination. For example, 100 parts of 10 per cent acetic acid ara treated with 50 parts of 70 per cent sulphuric acid and the distillation vapours sprayed with 70 per cent sulphuric acid, the acetic acid passing from the column having a concentration of about 90 per cent. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the manufacture of lightweight mineral material
IPC: G04B18/02
Filed: 1937-03-17
Abstract: Granules of exfoliated vermiculite are reinforced by a carbon coating by applying liquid or molten carbonaceous material, e.g. tar, pitch, asphalt or paraffin oil, to the granules and subjecting them to destructive distillation to leave a hard carbon residue on the granules.  The reinforced granules can be used as a lightweight aggregate for concrete, and as a heat insulating material.  The material may be used in the heat treatment of metals by surrounding the heated metal, e.g. a hot ingot, immediately after stripping, with the material, whereby loss of heat is prevented and, owing to the carbon coating, the metal is surrounded with a reducing atmosphere. Thus the material may be used in the steel industry for preventing oxidation and scaling of ingots in the soaking pits.  The granules may be withdrawn from the soaking pit by a suction pipe.ALSO:Granules of exfoliated vermiculite reinforced by a carbon coating are used as a heat insulating material in the heat treatment of metals, by surrounding the heated metal, e.g. a hot ingot immediately after stripping, with the material, whereby loss of heat is prevented and, owing to the carbon coating, the metal is surrounded with a reducing atmosphere.

Filed: 1958-03-11
Abstract: 875,118. Laminates; coated laminated materials; fabrics, finishing; craping. DU PONT DE NEMOURS & CO., E. T. March 11, 1958 [March 13, 1957], No. 7868/58. Classes 42 (1) and 140. [Also in Groups VII and IX] A pile or other fabric comprises a pleated facing 1, Fig. 11, and a pleated base 2 secured together along peaks 3 of the pleats by interweaving, sewing, stapling or adhesive. There may be a facing on both sides of the base. When the facing is a fabric, its pleats may be disposed transversely of the pleats in the base. When the face is pile, it may be cut or uncut. Pleating may be effected by inserting slats 7 between the face 1 and backing 2 and turning them up on edge as shown in Fig. 9, the fabric being heatset before the slats are removed. Or the fabric may be pleated' by feeding it into a stuffing-box. Alternatively, the pile and base may be pleated in the same direction by blades 14, 141 as shown in Fig. 14, heat set in a chamber 16, and passed round a perforated roller 17 which blows air through the pile 1 to reverse the pleats in the base 2. As shown in Fig. 5, the fabric may be woven with draw-cords 4 which are delivered at a slower rate than the pile warp 1 and the warp of the base 2; the fabric passes between knurled rollers which slide it along the draw-cords to produce the pleats. The fabric may be heat-set in the loom and the draw-cords may be withdrawn or destroyed, or the draw-cords may be anchored to the base by transverse stripes of adhesive at intervals corresponding to the desired length of a piece of fabric. Instead of running through the peaks 3 of the base, the draw-cords 4 may run through the peaks 5<SP>1</SP> or intermediately of the peaks' 3 and 5<SP>1</SP>. Wires fixed in the loom may be used instead of drawcords, the fabric being heat-set before it slides off them. A heat-set fabric having no drawcords 4 may be stretched flat and wound on a roll for transport or may have a pattern printed on it, release of the tension allowing it to revert to the pleated state. As shown in Fig. 11, the pleats of the back of the skeleton may be filled by coating with an elastomeric material 8, e.g. natural or synthetic rubber, rubber latex, sponge rubber, vinyl foam, polyurethane foam or any other material, e.g., thermoplastic or thermosetting resins, which have high elasticity. A backing sheet 9 may then be applied.
