Patent GB-992085-A (GB)
Title: Improvements in or relating to carbon articles
Inventor: JENKINS MANSELL JOHN
IPC: C04B35/52
Filed: 1963-03-14
Abstract: The porosity of a carbon article is reduced by incorporating in the article a resin formed by heat-treating a mixture of phenol and hexamethylene tetramine (hexamine), and subsequently heating the article, preferably to 350 DEG  C. at a rate not exceeding 10 DEG  C. per hour and then to 1000 DEG  C. at a rate not exceeding 6 DEG  C. per hour, to carbonize the resin.  The article may be graphitized by further heat treatment.  The resin may be incorporated by impregnation of the article, for example a self-cohering article of finely porous structure formed by baking a green mass of calcined pulverized coke mixed with a cokable binder such as coal tar pitch, with liquid resin, when preferably the molar ratio of phenol to hexamine in the liquid impregnant is 14 to 1 and the liquid is heated to form a stage 1 polymer before impregnation. Alternatively, the resin may be incorporated by binding a mass of loose particles of carbonaceous material of low volatile content, for example calcined pulverized coke, with the resin and forming the article either by extrusion when the resin binder is a liquid with a molar ratio of phenol to hexamine of 12 to 1 or by moulding when the resin binder is a solid with a molar ratio of phenol to hexamine of 6 to 1.

Patent GB-478330-A (GB)
Title: Process for the preparation of a new ergot alkaloid and its salts
Filed: 1936-04-08
Abstract: A new alkaloid, called ergobasine, is obtained from ergot by taking advantage of its relatively great solubility in water and its sparing solubility in chlorinated aliphatic hydrocarbons. Thus, the finely-powdered ergot is ground with water and the filtered solution, preferably after concentration in vacuo, is shaken with a large quantity of a chlorinated hydrocarbon, whereupon the extract is concentrated to allow the new alkaloid to crystallize out.  Again, an aqueous acid extract of ergot is treated with an alkali such as sodium bicarbonate and then shaken with a chlorinated aliphatic hydrocarbon such as chloroform; the first extracts contain the alkaloids of the ergotoxine-ergotamine group, whilst the later extracts contain the new alkaloid.  The new alkaloid is stated to be distinguished from ergometrine by the physical and chemical properties both of itself and its salts. According to the examples: (1) a benzene extract of ergot, prepared according to German Specification 357,272, is concentrated and the alkaloids precipitated by petroleum ether; the dried mixture is then ground with cold water and the united extracts shaken with a large quantity of chloroform; the new alkaloid is isolated by evaporation in vacuo of the solution, recrystallized from benzene and converted into its tartrate; (2) the benzene extract of (1) is concentrated, the alkaloids separating out are dissolved in a large quantity of chloroform and the solution allowed to stand in an ice box, when the new alkaloid separates out; after purification by recrystallization from benzene or from di- or tri-chlorethylene, it is converted into its hydrochloride; (3) a concentrated fluid extract of secale cornutum, which has been repeatedly concentrated in vacuo and the precipitate removed, is made alkaline with sodium bicarbonate solution and the aqueous filtrate extracted with large quantities of chloroform; the extract is treated with dilute sulphuric acid, the acid solution neutralized with sodium bicarbonate solution and the new alkaloid obtained by further extraction with chloroform; (4) an aqueous hydrochloric acid extract of ergot is neutralized with sodium bicarbonate, the concentrated filtrate extracted with a large quantity of chloroform and the isolated alkaloid, after recrystallization from dichlorethylene, converted into its hydrobromide; (5) a tincture from secale cornutum is freed from alcohol by low temperature distillation under reduced pressure, sodium bicarbonate solution added to the concentrated filtrate, and the new base extracted from the filtered solution by means of chloroform.

Title: Screw-loading press
Inventor: LEES JOHN
IPC: B01J3/06
Filed: 1967-03-06
Abstract: 1,216,851. Sample support for X-ray diffraction under high pressure; resistance heating. STANDARD TELEPHONES & CABLES Ltd. and H. J. MILLEDGE. 29 Feb., 1968 [6 March, 1967], No. 10379/67. Headings H5H and H5R. In the analysis of samples under high pressure by X-ray diffraction, the sample support comprises an annular cylinder or annular frustum of a core of boron carbide fitted into an aperture in a supporting member which member is provided with at least one slot perforating the member and opening on to the curved surface of the boron carbide insert, the central aperture of the boron carbide being fitted with two opposed pistons adapted to compress a cylindrical plug containing the sample, one piston being advanced relative to the other by rotation of a loading screw. Preferably the supporting member is a ring and two slots lie in a plane transverse to the axis of the frustum or cylinder, each slot opening on to a diametrically opposed portion of the boron carbide insert. Thus as shown in Figs. 1 and 1b which show two sectional views at right angles to each other of a suitable apparatus, boron carbide insert 16 containing sample tube 5 is supported in an annulus 17 which has slots, extending from its outer to its inner circumference, cut parallel to the face of the annulus. The press consists of upper part 1 connected to base-plate 3 by bolts 4 threaded into webs 2 extending down from upper part 1. Lower piston 9 rests in a cavity in base-plate 3 and upper piston 8 slides in an axial hole in block 1 impelled by the narrow extension 12 extending from the loading screw 13. The sample container 5 in the axial orifice of the insert is compressed between two narrow coaxial extensions 6 of the upper and lower pistons. Plastics washer 15 prevents the rotation of the loading screw being imparted to the piston. The sample container 5 consists of a thin walled nickel sleeve 20 within which a specimen 21 is inserted, the voids in the container being filled with a resin (Fig. 3). The specimen may be heated by resistance heating by passing a current through the sleeve, and to this end block 1 and bolts 4 are insulated from the base-plate 3 by mica layer 25 and insulating sleeves 26, the boron carbide of the insert being a sufficiently poor conductor of electricity that no significant current passes between the pistons through the insert rather than the sample holder.

Title: Improvement in electrowinning of chromium
IPC: C25C1/10
Filed: 1952-04-25
Abstract: An iron-chromium alloy is leached at stage 1 of the flow sheet with liquor containing sulphuric acid and ammonium sulphate recycled from a later stage of the process, make-up acid and ammonium sulphate crystals being added as necessary.  The product is filtered at 2 and the filtrate heated at 3, e.g. to 80 DEG C., and cooled at 4, e.g. to 5-10 DEG C., to crystallise out crude iron ammonium sulphate which is filtered off at 5.  The filtrate is aged at 10 to crystallize out chromium <PICT:0703220/III/1> ammonium alum which is washed and filtered off at 11, the crystals being redissolved at 12 and passed to the cathode compartment of an electrolytic cell at 13 for electrodeposition of chromium (see Group XXXVI).  A mixture of chromic acid and sulphuric acid formed in the anode compartment is treated with a reducing agent, e.g. molasses at 14 to restore chromium to the trivalent state and recycled to the leaching tank. The mother liquor containing chromium ammonium alum from stage 11 is returned to the leaching tank, mainly directly, but a minor portion is purified by treatment at 15 with a hot aqueous solution of an alkali or alkaline earth metal base, such as sodium carbonate, under non-oxidizing conditions, forming a granular precipitate of basic chromium sulphate which is filtered off and washed at 16 and passed to the leaching tank.  The addition of mother liquor to the basic solution at 15 is continued until a pH of 3.8 is reached initial precipitates of metallic impurities being then redissolved.  Overflow from the cathode compartment of the electrolytic cell is recycled to stage 10.  Crude iron ammonium sulphate from 5 is redissolved at 6, heated at 7, e.g. to 80 DEG C., cooled at 8, e.g. to 5-10 DEG C., to recrystallize and filtered off at 9, the filtrate being recycled to stage 3.

Abstract: 805,834. Blow-moulding hollow plastic articles. SHIPTON & CO. Ltd., E. April 9, 1956 [April 12, 1955 ; Oct. 24, 1955], Nos. 10459/55 and 30347/55. Class 87(2). [Also in Group XL(b)] In a machine for blowing hollow articles by extruding a tube of plastic material into a tow-part mould 55, and then blowing the tube in the mould, the drive to the extrusion screw 3 is stopped, when a desired length of tube has been extruded, by a photo-electric cell 78 which disengages a clutch 28, In operation when the light from a source 74 is interrupted by the tube, the cell 78 energises a coil causing the clutch 28 to be disengaged, and operating a valve 83 which allows air to be supplied to a cylinder 44. The piston-rod 43 of the cylinder 44 rotates a valve 11 to allow the plastic material to be fed to a desired nozzle. At the same time, a boss 46 on the rod 43 operates valves as follows : (a) valve 19R to cut off the air supply to the right extrusion nozzle (b) valve 73L to prevent the left ejecting cylinder 72L from operating (c) valve 58L to close the left mould around the extruded tube (d) valve 58R to open the right mould (e) valve 19L to supply air to the left nozzle to blow the hollow article, and (f) valve 73R to eject the hollow article suspended on the right nozzle. After a predetermined time, the valve 83 is restored, the clutch 28 is re-engaged, and the extrusion begins from the other nozzle. The electrical timing circuit (see Fig. 7, not shown) may include a counter and relays to stop the supply to the motor if the light fails. The invention may also be applied to a single nozzle machine which may operate with several moulds successively moved into position on a rotary table as described in Specification 564,350. Different sizes of bottles may be made by adjusting the position of the light and the cell. The position of the cell may be adjusted automatically in a controlled sequence or by cams. The moulds 55, Fig. 3, are fixed on adjustable tables 22. Openings 80 are provided to prevent the moulds interrupting the light beam. The mould halves are mounted on pivoted links, and are provided with walls 69, to close the lower end of the tube, and cutting parts 70. The formed bottles are ejected by forked members 71. Flow regulators may be fitted to the various cylinders to control e.g. the speed of the piston rod 43, and the mould opening and closing speeds. Specifications 700,984 and 794,730 also are referred to.
