Abstract: 238,008. Cargo, W. F. May 9, 1924. Gathering molten metal.-Relates to a suction gathering device of the kind in which a charging-head swings about a vertical shaft between the tank furnace and a forming-machine, and consists in making the charging-head in two parts which open out to allow the charge to drop into a parison mould. The machine is operated by compressed air and is shown in conjunction with a forming-machine of the kind described in Specification 234,203, and with a tank furnace having an open-topped fore-hearth 2. The device comprises a vertical column 9, which is journaled in bearings in a pillar 8 and is oscillated by an air cylinder 14, a charging-head 23, shears 51, and a skimming-blade 40. The head 23 consists of two halves 34 pivoted on a bracket 30, and the bracket is pivoted to a parallel-motion device consisting of two pairs of arms 31, 32 hinged to a bracket 19 on the column 9. The arms 31, 32 are raised and lowered by an air cylinder 21, the position of which can be adjusted by a handwheel 26 to regulate the amount by which the head dips into the metal in the forehearth. Suction is applied to the head through a flexible pipe attached to a cover 35, and shears 51, pivoted on a bracket 17 and actuated by an air cylinder 53, cut off the string of glass as the head 23 is raised. The parts 34 of the head are closed by a spring 66 which acts on a bar that slides on the bars 31 and is connected to the parts 34. A roller 63 on the slide engages a groove in a cam 62, secured to the pillar 8, when the head 23 is raised. The cam causes the halves of the head to open when the head is swung over the parison mould and thus to drop the charge into the mould. The skimming-blade 40 is carried by an arm 42 which is connected to the parallel-motion by links. The blade dips into the molten glass as the head is swung into the forehearth, and clears the glass before the head is dipped to receive a charge.
Patent GB-813163-A (GB)
Title: Extraction of amines
IPC: B01J47/00
Filed: 1957-04-09
Abstract: Diamines and higher polyamines, e.g. those obtained by reaction of dichlorinated alkanes with ammonia, are extracted from aqueous solutions of their hydrochlorides by contacting the solution with an ion exchange material, washing the ion exchange material with water, regenerating it in any known manner, extracting the amines from the solution by direct distillation, and re-cycling the solution obtained from the washing stage.  Suitable resins are anion exchangers, such as quaternary ammonium resins, in the OH form, and cation exchangers, such as those containing sulphonic acid groups, in the H form or in the salt form.  When using cation exchangers the amines are adsorbed on the resin as salts and are eluted with an alkaline solution.  In examples the mixture obtained by reacting dichloroethane with ammonia is treated with (1) the quaternary ammonium resin Amberlite 1R410; (2), (3) the sulphonic acid type resin Amberlite IR120 in the acid form; (4)-(8) Amberlite IR120 in the sodium salt form ("Amberlite" is a Registered Trade Mark).  Example (9) describes the separation of ethylenediamine by distillation from its solution containing caustic soda obtained in Examples (2)-(8).

Title: Improvements in the art of and means for the treating of hydrocarbon oils
IPC: C10G47/00
Filed: 1920-04-27
Abstract: 166,989. Engelke, E. F. April 27, 1920. Mineral oils. - In distilling hydrocarbon oils so as to obtain increased amounts of low boiling saturated hydrocarbons, the preheated oil is run down a tower containing a packing of catalytic material, such as charcoal, coke, or iron copper or nickel rings, up which a current of heated gas .containing free hydrogen is passed. The tower T may be heated by a jacket through which hot gases, such as those from the furnace of the preheaters, pass. Hydrogen-containing gas heated in a coil G is passed into the base of the tower, and oil heated in a coil O is sprayed into the top of the tower on to the packing. The vapours pass through a dephlegmator D kept at a constant temperature by hot residual oil, superheated steam or hot gases, and thence to a condenser C. The uncondensed gas, if rich in hydrogen, may be returned to the circuit or may be burned. The heavy fractions condensed in the dephlegmator may be passed down the tower or may be mixed with the residual oil which collects at the base and returned with it through the tower. The residual oils may be treated in the base of the tower with heated gas, which may be mixed with superheated steam, injected through a perforated coil C. The apparatus is kept under pressure by a relief valve R<4> on the condenser outlet.
Patent GB-655118-A (GB)
Title: Improvements in or relating to the production of aliphatic di-ketones
IPC: C07C45/53
Filed: 1948-04-29
Abstract: Aliphatic diketones are prepared by reacting a solution of a ferrous salt in an aqueous medium with a hydroperoxide of a saturated alicyclic hydrocarbon wherein the peroxide group is linked to a tertiary carbon atom which forms part of the alicyclic ring and which bears at the same time an alkyl group.  In the reaction, one molecule of the ferrous salt reacts with one molecule of the hydroperoxide, whereby fission of the linkage between the tertiary carbon atom and an adjacent carbon atom takes place and identical radicals link up to form diketones having double the number of carbon atoms in the molecule.  Reference is made to the treatment of hydroperoxides of methyl cyclopentane, ethyl cyclopentane, isopropyl cyclopentane, methyl cyclohexane and ethyl cyclohexane.  Suitable ferrous salts are the sulphate, chloride, acetate and lactate.  The process may be carried out by bringing the hydroperoxide into intimate contact with ferrous sulphate dissolved, preferably in aqueous solution. Alternatively, the hydroperoxide may be employed in solution; such a solution may be that obtained when the alicyclic hydrocarbon is oxidized by means of molecular oxygen for the production of the hydroperoxide, without removal of the latter from unchanged hydrocarbon.  The process of the invention may be carried out in neutral solution, alkaline solution in which case the hydroperoxides form their alkali salts, or preferably in acid solution, generally using sufficient mineral acid to prevent precipitation of iron.  In addition to the diketones, other ketones and alcohols are formed as by-products.  In examples: (1) methyl cyclopentane hydroperoxide is shaken with aqueous ferrous sulphate solution yielding dodecanedione-2 : 11 and, among by-products, methyl butyl ketone; (2) methyl cyclohexane hydroperoxide is treated likewise and yields tetradecanedione-2 : 13; (3) methyl cyclopentane hydroperoxide is treated as in (1) in aqueous alcoholic solution acidified with sulphuric acid, or (4) in the form of sodium salt of the hydroperoxide in aqueous solution.  The Provisional Specification defines the hydroperoxides as those wherein the peroxide group is attached to a tertiary carbon atom which forms part of the ring of a saturated alicyclic hydrocarbon.
