Title: Improvements in or relating to purification of pentaerythritol
IPC: C07C31/24
Filed: 1957-01-30
Abstract: Pentaerythritol is purified by continuously contacting an aqueous solution of a crude pentaerythritol containing bispentaerythritol monoformal with a strongly acidic cation exchange resin at a flow rate not greater than 4 gallons per cubic foot of resin per minute at a temperature in the range 50-150 DEG  C., whereby the bispentaerythritol is converted to pentaerythritol monoformal, and recovering the pentaerythritol from the effluent solution by crystallization, the pentaerythritol monoformal remaining in the mother liquor.  Suitable resins are for example the nuclear sulphonic acid type cation exchange resins or strongly acidic carboxylic acid type cation exchange resins such as chloroacetic acid containing resins.  Crystallization of the effluent can be effected by either evaporation or cooling or a combination of both.  In the examples crude pentaerythritol containing about 10 per cent of bispentaerythritol monoformal is dissolved in water and the solution is passed through an elongated ion exchange vessel containing hydrogen-active sulphonated cation exchange resin prepared by the sulphonation with chlorosulphonic acid of a resinous copolymer of styrene and divinyl benzine, at a flow rate not greater than 4 gallons per cubic foot of resin per minute; the effluent from the ion exchange resin is partially evaporated and cooled to 25 DEG  C. to crystallize pentaerythritol.

Title: Improvements in chuck-collets
IPC: B23Q3/06
Filed: 1930-01-31
Abstract: 342,523. Grinding. VAN NORMAN MACHINE TOOL CO., 160, Wilbraham Avenue, Springfield, Massachusetts, U.S.A. Jan. 31, 1930, No. 3335. Convention date, May 18, 1929. [Class 60.] Processes, special.-In making double-ended chuck collets from tubular blanks, the tempering process produces a slight distortion of the flexible bars so that the internal diameter is greater in the middle than at the ends, and these end portions are lapped to a correct cylindrical form by means of an internal cylindrical lap having a diameter equal to that ot the collet in the expanded condition. The outer surfaces of the gripping fingers 44 are then shaped to a spheroidal form whilst the collet is contracted by means of chuck jaws 62, Fig. 9, on to a mandrel 63 of diameter equal to that of the smallest workpiece for which the chuck is designed. The spheroidal surfaces 68 are produced by a grinding disc 65 which is shaped to the correct form or is oscillated relatively to the collet, the latter being rotated during grinding. The centre of curvature of the surfaces 68 is situated on the axis of the mandrel 63 but the radius is large so that the surfaces are nearly conical. Should the bars 45 become distorted during manufacture so that some of the interior end surfaces 66, Fig. 19, which were lapped concentrically whilst the collet was expanded assume an unsymmetrical position as shown in Fig. 19 in the contracted condition, a further grinding operation is performed in which the collet is mounted on an arbor 77, Fig. 22, approximately equal in diameter to the largest work-piece for which the chuck is designed and the spheroidal surfaces are again ground at this enlarged radius, thus producing faces 79 concentric with the collet in the expanded condition. In preference all collets, whether of correct form or not, are given this second grinding and further grindings may be performed on arbors of diameters intermediate of the expanded and contracted conditions in order to ensure that for each diameter there will be portions of the spheroidal surfaces making contact with the closing cones of the chuck and also concentric with the gripping surfaces 66 at that diameter. This subsequent grinding is preferably performed with a grinding wheel which gives the collet a spheroidal surface of larger radius of curvature than the first grinding.

Title: Method of continuous separation by countercurrent absorption in gaseous phase
IPC: C07C7/12
Filed: 1968-01-24
Abstract: 1,213,523. Separation of gaseous mixtures. SOC. DE RECHERCHES TECHNIQUES ET INDUSTRIELLES. 24 Jan., 1968 [31 Jan., 1967; 18 Aug., 1967], No. 3641/68. Heading B1L. A gaseous mixture whose components are to be separated is fed to an intermediate point of a column by line 1, down through which colmn as passing a granular support material which is impregnated with a suitable differential absorbing liquid, so that as the gas passes up the column through the impregnated material ithe streams are moving in countercurrent. The least strongly absorbed components are withdrawn at 2 and the most strongly absorbed components are taken off at 3. As the support material and absorbent passes down the column it passes in turn through purge zone 13, the gas flow leaving which is recycled as desired by line 4 to input line 1, through depletion zone 19, through enrichment zone 21 and finally through desorption zone 15 before leaving through flow regulator 22. The temperature in the various zones is maintained at the appropriate levels by heat exchangers 38, 39 and 40. Gas leaving the colmn by line 27 is separated from fires in cyclone 28 and then passes by line 30 to pneumatic transport unit 25 to carry impregnated solid leaving flow meter 23 up through line 26 to separator 16 and thence back to the head of the column. The binary separation process described is capable of elaboration for the separation of n-component mixtures, and is described in detail in connection with Fig. 3 (not shown) for the separation of a tertiary mixture. A particularly suitable support material is Celite C22 (registered Trade Mark) impregnated as suitable with hydrocarbons, esters, ethers, glycols, silicones and certain other specific solvents, a large number of such absorbing liquids being specified. The process may be applied to the separation of mixtures of hydrocarbons, alcohols, sterols, aldehydes, ketones, amines (including pyridines and picolines), and organic halogen and sulphur compounds.

Title: Improvements in or relating to apparatus for electric brazing or the like
IPC: H01H11/04
Filed: 1944-03-01
Abstract: 583,230. Supply systems for resistance welding and the like. IGRANIC ELECTRIC CO., Ltd. March 1, 1944, No. 3871. Convention date, March 1, 1943. [Class 38 (iv)] A supply system for a spot welding or brazing transformer 6 includes in circuit with the transformer a variable reactance, such as a choke 10, the impedance of which is automatically increased at a controlled rate upon flow of current, so that the energization of the transformer is reduced as the welding &c. operation proceeds. The iron circuit of the choke may comprise a fixed portion 12 and a movable portion 13 pivoted to the former and constituting a yoke which is normally biassed away from the fixed portion by a weight 14. As the yoke is attracted to the fixed portion by current flowing in the winding 11, the inductance of the choke increases at a rate determined by a dashpot 15 connected to the yoke. The welding &c. operation is effected as follows : with the work 1 placed between the electrodes 3, 4, starting switch 18 is closed, thereby energizing a self-holding contactor 9 which connects the choke and transformer primary across the supply lines. Welding proceeds with diminishing current until the holding circuit of contactor 9 is interrupted by a stud 20 carried by yoke 13 opening a normally closed switch 19. In a modified arrangement, the choke is arranged to shunt current from a spot-welding circuit, so that the welding current is progressively increased. In another arrangement, a condenser replaces the choke as the variable reactance.

Title: Improvements in draft regulating means for stoves and the like
IPC: F24C15/34
Filed: 1933-02-10
Abstract: 399,082. Regulating draught in stoves; burners. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Lidingo, near Stockholm. Feb. 10, 1933, No. 4130. Convention date, March 2, 1932. [Classes 75 (i) and 126.] To regulate the draught in a stove or the like by eliminating the effect of variations in the chimney draught, a chamber 9, Fig. 1, offering small resistance to the passage of air and open at one end 11 to the atmosphere is employed, the whole of the air for combustion being taken from this chamber near to the open end by a pipe 12, and the other end of the chamber communicating with the stove outlet flue 8 and chimney 10. The broken line 16 represents the boundary under normal chimney draught between the hot flue gases in the upper part of the chamber 9 and the air in the remaining space. Under increased chimney draught, the boundary rises towards a position 15 in which air is drawn into the chimney, whilst a diminished draught causes the boundary to sink towards a position 14, in which the passage of air to the chimney diminishes or ceases. Continuous abnormal back-draught causes the flue gases to pass to the bottom of the chamber 9, cutting off the supply of air through the tube 12 and causing temporary cessation of combustion. To avoid local circulation of the gases in the chamber 9, at least the upper portion is of small cross-section in relation to its height, and gridlike partitions or baffles may be provided ; the walls of the chamber may be of material of high heat conductivity to avoid local temperature differences tending to set up circulation of the gases in it. The heat-accumulating hotplate stove, shown in Fig. 1, is heated by an oil burner 5, oil being supplied from a tank 18 in the chamber 9 to a vaporizing chamber 2, and the vapour being mixed in a chamber 13 with air supplied through the pipe 12. Fig. 2 shows a heat-accumulating cooking stove heated by a gas burner comprising perforated tubes 28, 29, to the space between which gas is supplied from a base member 20. Air is supplied by pipes 22, 23 to the spaces around and within the burner, combustion occurring in the annular space between the tubes 28, 29, and the gases passing by a pipe 21 to a chamber 27 and thence by a pipe 31 to the chimney. The draught-regulating chamber is formed by a pipe 32 opening at the top into the pipe 31, and having a horizontal portion the end of which is open to the atmosphere, and from which the pipes 22, 23 lead.
