Title: Improvements in or relating to the preparation of 3-pyridinols
Inventor: ELMING NIELS
IPC: C07D213/66
Filed: 1957-01-02
Abstract: 3-Pyridinols of the formula: <FORM:0862581/IV (b)/1> (wherein Z is hydrogen or CH2OH and R2 and R4 are hydrogen or alkyl) are prepared by oxidizing substituted furans of the formula: <FORM:0862581/IV (b)/2> (wherein Y is hydrogen or CH2OR1, R1 being hydrogen or aryl, and R5 is an amino group or a protected amino group) or acid-addition salts thereof by a halogen in water or by other chemical oxidizing agents in water or an aqueous or anhydrous alcohol ROH (wherein R is an alkyl, hydroxyalkyl or cycloalkyl group of not more than 6 carbon atoms) and hydrolysing to produce the required 3-pyridinol.  Suitable oxidizing agents include oxyhalogenic and hypohalogenous acids and their salts, hydrogen peroxide, inorganic peroxy acids and salts thereof, organic peracids, dichromates and chromic acid, permanganates, nitric acid and nitrogen oxides.  The oxidation product formed is directly hydrolysed to the 3-pyridinol, and the oxidation and hydrolysis are desirably effected at a pH of between zero and 10, the pH being adjusted if necessary by addition of an organic or mineral acid, preferably hydrochloric acid.  An oxidation catalyst, such as ferrous sulphate or vanadium pentoxide, may also be added.  Protection of the amino group in the starting material may be effected by conversion to the corresponding acyl, carbamate or N-mono- or N-di-carbamoyl derivative, but the amino group, and the CH2OH groups when present, are preferably free.  Numerous examples describe the preparation of 3-pyridinol ,2-methyl-3-pyridinol and pyridoxine by the process of the invention using a variety of oxidizing agents, and a further example describes the oxidation of 2-(a -aminoethyl)-3:4-bis-(hydroxymethyl)-furan to 2-(a -aminoethyl)-3:4-bis-(hydroxymethyl) - 2:5- dimethoxy-and-diethoxy-2:5-dihydrofurans using aqueous sodium hypochlorite and hydrochloric acid in methanol and ethanol respectively, without a subsequent hydrolysis.  The Provisional Specification refers to the use of anhydrous alcohols, aqueous alcohols, water and other solvents in general as reaction media in the oxidation process, and provides two further examples illustrating the oxidizing action of chlorine in aqueous methanol.

Abstract: 1,148,400. Extruding socketed pipes. P.M.E.- HOLDING A.G. 3 Jan., 1967 [2 Feb., 1966], No. 328/67. Heading B5A. A socketed plastics pipe is made by extruding material through annular passageway 3 of diehead 1, between a core 7 and jacket 21 which define the socket and through a passageway 25 where the material is sized to the pipe dimensions by a core 9 and further jacket 23. Material emerging from passageway 25 engages ribs 45 on a rod 41, and to form an extended pipe length, rod 41 is moved axially away from die head 1 at the speed of extrusion by rolls 43, see also Fig. 2 (not reproduced). When a predetermined length has been extruded, core 7 is released from die-head 1 by rotating rod 29 via system 31-33, 39 and 40 whereupon screwthreaded end 30 disengages from a screwthreaded socket 15 within the core. Furthermore jackets 21 and 23 which are sectionalized, are moved radially to release the socket and adjacent pipe length, see Fig. 3 (not reproduced). Finally the extrudate is severed adjacent die head 1 by a rotatable knife (51), Fig. 3 (not shown), and at its downstream end by knife (53), Fig. 4 (not shown). Cores 7 and 9 are removed from the socket by contracting a bead-forming member 11. This member is composed of segments 11a, 11b, Fig. 5, which are moved radially inwardly by axial movement of wedges 14, see also Figs. 6a, 6b and 7 (not reproduced). Components 7, 9, 21, 23, 41, 43 and 49 may be duplicated, one set being moved transversely to die head 1 after extrusion and the other set being attached thereto to allow virtually non-stop extrusion. Jackets 21, 23 contain circulating heat-transfer liquid, with generally jacket 23 being at lower temperature than jacket 21, and the extrudate is cooled by sprays from pipes 49. Core 7 may be heated electrically or by fluid flow. Rod 41 may be dispensed with, advancement of the tube being solely due to the extrusion pressure.

Title: Improvements in and relating to the manufacture of rubber
IPC: C08C19/04
Filed: 1931-01-09
Abstract: A soft rubber is produced by exposing crude rubber in dry condition and without mechanical working to an oxidizing atmosphere at a sufficiently elevated temperature, e.g. 330-347 DEG  F. and for a sufficient time to produce an increase of weight of at least ,5 per cent and preferably of about 2 per cent. Preferably the rubber is first heated under non-oxidizing conditions, e.g. under reduced pressure, and then under oxidizing conditions which are continued while the rubber cools.  The rubber is preferably in crumb or sheet form to present an extended surface to the oxidizing gases.  In an example, rubber as received from the plantation is reduced to crumb, charged on to trays, and heated in vacuo to 340-345 DEG  F. for two hours; air is then admitted and the heating continued for about 45 minutes; the trays are then removed from the oven, piled in such a manner as to allow free circulation of air, and allowed to cool for about 45 minutes to about 120 DEG  F.; the crumb is then homogenized by masticating for 3 to 5 minutes.  Specification 314,783, [Class 70, Indiarubber &c.], is referred to.

Abstract: 157,124. Waltz, E., and Meusser, H. Dec. 2, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Codensers.-In apparatus for recording and reproducing motion successions, applicable to sound succession reliefs and picture and photo reliefs, the motions are caused to effect electric capacity-value variations in a condenser in a highfrequency circuit, and these variations are transformed by a cathode ray or vacuum intensifier into current intensity variations which can be recorded, transmitted or reproduced. In one arrangement shown, the condenser comprises a series of movable discs or foils b, Fig. 5, alternating with a series of stationary annular discs or foils a and connected by a rod operable by a bell-crank h movable on a pivot v by action of a mechanical relief f on a stylus s to varv the distance between the two sets of discs and thereby the capacity. The fixed discs a and also the movable discs b may be connected in parallel in a high frequency circuit, or alternating fixed discs a may be in parallel and of opposite polarity to the intervening fixed discs, and in this arrangement the movable discs may or mav not be connected in the electrical circuit according to whether the minimum capacity is to be at the full displacement of the movable discs cr at their mid position. The position of rest of the movable discs is controlled by a diaphragm m or other means, and may be so chosen that capacity variations of " double frequency " to be recorded or reproduced in the form of " double frequencies " may be effected. The reproduction arrangements may be such as respond to variations in absolute capacity or to capacity variations only, according to the purpose.
