Patent GB-657254-A (GB)
Title: Process for the manufacture of folic acid
Filed: 1949-01-20
Abstract: Folic acid is prepared by reacting in solution, 2 : 4 : 5 - triamino - 6 - hydroxy - pyrimidine, glycero - aldehyde - ditoluene - parasulphonic acid ester, para-aminobenzoyl-L(+)-glutamic acid and a salt of hydriodic acid. A suitable salt mentioned is potassium iodide.  Acrolein is formed by the action of a salt of hydriodic acid on glyceraldehyde - ditoluene - para - L(+) - glutamic acid in the usual way so that in the reaction to form folic acid, acrolein or a ,b -diiodo-glyceraldehyde may be formed in situ, which then reacts with the triamino-hydroxy-pyrimidine and the aminobenzoyl-glutamic acid.  The Specification as open to inspection under Sect. 91, refers to the use of any glyceroaldehyde di-toluene sulphonic acid ester for the above process.  This subject-matter does not appear in the Specification as accepted.
Patent GB-702023-A (GB)
Title: Method of and apparatus for the manufacture of artificial filaments, threads and the like
IPC: D01D5/06
Filed: 1952-01-22
Abstract: Viscose is extruded into a coagulating bath to form a thread, and the thread is withdrawn from the bath, formed into at least two helices and subjected to a series of liquid treatments and to drying, the steam or hot water used for drying one thread helix being passed about the external periphery of the first thread helix.  As shown, viscose is extruded as a thread 12 and is withdrawn from the coagulating bath by a take-up reel 15.  It is processed on reels 16 ... 19 and, finally, dried on reel 20.  The drying reel is internally heated by steam, preferably under pressure, from a supply 22, and the steam, after circulating through the reel 20, is led off through a take-off conduit 26 to a manifold 28 located near the thread take-up reel 15.  The steam flowing from the manifold is forced through openings 30 outwardly and toward reel 15, enveloping it and wetting the thread, thus preventing deposition of salt crystals.  When <PICT:0702023/IV(a)/1> using low-pressure steam a trap 31 may be inserted in the lowest part of the conduit 26 to separate out the condensate.

Abstract: 432,119. Tables. ANDERSON, W., Glen Cottage, Earl's Dene, Low Fell, Co. Durham. Jan. 22, 1934, No. 2138. [Class 52 (iii)] In an X-form framework for supporting a table top or tray, the pivots connecting the legs are offset from the lines of intersection of the legs. As shown in Fig. 1, the top B is pivoted at A to the legs C, and the legs C are pivoted to the legs E at a point D which is not in the lines at which the parts C, E intersect. The legs are prevented from opening too far by stops M. A spring L folds the legs together when the table is lifted from the ground ; they are unfolded by pressing the lower ends of the folded legs C against the ground, at the same time pressing down the parts near the pivots A. Alternatively the spring L may be omitted and the legs E weighted. In a modification, various leg members are steel tubes ; the bracings Fare omitted, and are replaced by uprights N, Fig. 7, connected by cross members O, P. The members E at their lower ends are pivoted to parts Q which slide in the uprights N. The pivot at each end of the cross member P consists of a wood screw screwed into a plug. The bracket T is formed with a stop to prevent the framing from swinging back too far.

Title: Recovery of palladium from catalysts
Inventor: LAIT RAYMOND
IPC: C22B11/06
Filed: 1959-01-22
Abstract: Palladium is recovered from a deactivated catalyst by stripping the palladium from the support by slurrying with hydrochloric acid and passing chlorine gas in to form a palladium-containing solution, removing insoluble materials from the solution and precipitating palladium from the solution by the addition of a more electropositive metal, e.g. aluminium or magnesium.  Prior to treatment the catalyst may be cleaned either by washing with an organic solvent, e.g. xylene followed by steam heating to remove the solvent or by heating in air, both steps being followed by washing with an alkaline reducing agent. The palladium recovered may be further purified by dissolving it in hydrochloric acid while passing chlorine gas in and filtering to removing insolubles.  Ammonium hydroxide is then added to the filtrate and the mixture warmed to redissolve the palladium complex and give Pd(NH3)4 Cl2.  Insolubles are again filtered off and the filtrate acidified with hydrochloric acid to give Pd(NH3)2 Cl2 as a precipitate.  This precipitate is then either treated with hydrazine hydrate or heated in hydrogen to give pure palladium.  The recovered or refined palladium may be dissolved in hydrochloric acid whilst passing gaseous chlorine through the mixture to give a solution of palladium chloride for the production of a catalyst by the methods described in Specifications 718,306, 746,385, 760,737 and 922,022. Specification 456,070 also is referred to.ALSO:Palladium is recovered from a deactivated catalyst by stripping the palladium from the support by slurrying with hydrochloric acid and passing chlorine gas in to form a palladium-containing solution, removing insoluble materials from the solution and precipitating palladium from the solution by the addition of a more electropositive metal, e.g. aluminium or magnesium.

IPC: B22C9/12
Filed: 1953-01-29
Abstract: 733,709. Drying refractory objects. COMPAGNIE ROYALE ASTURIENNE DES MINES. Jan. 29, 1953, No. 2631/53. Class 34 (2). In the drying of crucibles, muffles and like refractory objects, a specimen is brought gradually, in a moisture-saturated atmosphere in a test chamber, to a temperature of 35- 40‹ C. and then heated under conditions of controlled ventilation and finally under gradually increasing temperature to obtain a predetermined contraction of the specimen which indicates completion of drying and the objects to be dried are then submitted to similar conditions in a drying chamber with the use of temperatures and durations of heating &c. determined from data obtained in the test on the specimen. In a preferred method the test includes three stages, viz (1) slow and progressive heating for two hours in a saturated atmosphere to reach a temperature of 35-40‹ C.; (2) drying at this temperature for about 15 hours. with ventilation by natural draught to obtain a contraction causing a decrease in height of the specimen of the order of two millimetres per hour; (3) drying at a temperature rising gradually to 70-80‹ C. with increasing ventilation by forced draught to obtain a decrease of height of two to three millimetres per hour. The test chamber, a wooden cabinet lined with heatinsulating material, has a platform 5 to support the specimens 18 and beneath which are electric resistance heaters 6. Dampers 9, 10 and a fan 11 provide means for forced or natural draught and the decrease in height of the specimen is measured by a recording device 12 comprising a drum 13 rotated by clockwork mechanism and carrying a chart upon which a pen 14, carried by a rod 15 sliding in a tube 16 and resting on the top of the specimen 18, draws a trace. The main drying chamber has its base covered with a lattice structure 24 upon which the objects 25 are supported, heating being by finned steam pipes 26 and air intakes 29 and vents 30 connected to a central discharge conduit 31 which may be connected to a fan 33, providing means for ventilation. Measurement of contraction of the objects is by means of a recording device 37 having a pen 39 carried by a rod 40 sliding in a tube 41 and resting on top of one of the objects. The chamber also has thermometers and psychrometers which may be observed through windows 27, 28.
