Title: Process for the Production of p-Hydroxy Benzoic Acid
IPC: C07C51/48
Filed: 1968-03-29
Abstract: 1,189,385. p-Hydroxybenzoic acid. UENO PHARMACEUTICAL CO. Ltd. 29 March, 1968 [2 Oct., 1967; 8 Nov., 1967; 17 Jan., 1968; 18 Jan., 1968; 5 Feb., 1968], No. 15146/68. Heading C2C. A process for the production of p-hydroxy benzoic acid by reacting potassium phenoxide with carbon dioxide, comprises suspending potassium phenoxide in a liquid hydrocarbon boiling at 180-350 C. at atmospheric pressure and which consists of kerosene, light oil or mixtures thereof, or suspending potassium phenoxide, together with 0À01-10 moles of phenol per mole of potassium phenoxide, in a reaction medium which is liquid under the reaction conditions and in which potassium phenoxide is insoluble, e.g. kerosene, light oil or mixtures thereof, diphenyl, diphenyl ether or polychlorodiphenyl, and heating the suspension while maintaining it in the liquid phase with carbon dioxide at a pressure not exceeding 30 kg./cm.<SP>2</SP> and at a temperature not lower than 180 C. The reactants are preferably finely dispersed in the reaction medium by means of mechanical agitation. An aqueous solution of potassium phenoxide containing up to 20% of water may be used as a starting material and is dehydrated prior to reaction with carbon dioxide by heating its suspension in kerosene, light oil or mixtures thereof at 200-250 C. for no longer than 10 seconds. The reaction mixture obtained after the reaction with carbon dioxide may be worked up by adding water, thereby distributing the phenol, formed as a by-product, between an aqueous layer and a liquid hydrocarbon layer in the presence of p-hydroxy benzoic acid or a mono-potassium salt thereof in an amount at least equivalent to the unreacted potassium phenoxide, separating and recovering the phenol from the liquid hydrocarbon layer, separately extracting the phenol from the aqueous layer with a liquid medium which dissolves phenol but is immiscible with water, at a temperature not higher than 100 C. and recovering p-hydroxy benzoic acid from the aqueous layer remaining. The phenolic solution can be neutralized with aqueous caustic potash and the potassium phenoxide formed recycled to the initial stage. Alternatively, after the reaction with carbon dioxide, the molar ratio between dipotassium p-hydroxy benzoate to phenol in the reaction mixture is adjusted to between 1:1 and 1:30, thus forming a liquid phase containing the phenol-potassium phenoxide mixture and a solid phase consisting of potassium p-hydroxy benzoates, which on treatment with acid yield p-hydroxy benzoic acid.

Title: Knitting apparatus for the distribution of jacquard pattern surfaces
IPC: D04B15/66
Filed: 1972-04-04
Abstract: 1389323 Knitting machines; pattern mechanisms EDOUARD DUBIED & CIE SA 4 April 1972 [6 April 1971] 15368/72 Heading D1C [Also in Division G3] A knitted area consists of a plurality of Jacquard pattern surfaces arranged in any particular array and a circular knitting machine is controlled by logic circuitry to produce the required overall pattern. Figure 5 shows a typical pattern that is required where 49c is the repeated pattern surface and 49f is a background pattern. The plugboard 1 shown under the pattern is the crosspoint matrix 1 shown in Figure 1 and the active crosspoints are those under each pattern surface. In the example shown each pattern surface is 100 x 120 stitches and these figures are set into the X and Y selectors 9 and 16 respectively. The overall size of the area is 8 x 7 repeats of the pattern surface and these figures are set into selectors 15 and 22 respectively. In operation the machine control 8 is arranged to knit background pattern determined by colour bar 24 unless matrix 1 gives an output when the stitches knitted are determined by memory 2. The Jacquard circular knitting machine is stated to have 36 knitting posts. Control System (Figure 1) Memory 2 contains the details of each stitch in the required pattern surface or surfaces and is addressed by decoders 6 and 7 which are supplied with the stitch location parameters x, y. These parameters are calculated in calculators 4, 5 which operate in conjunction with the devices 9-15, 16-20 which compute the values shown in binary code. At the end of each pattern surface, which is defined by the number set on selectors 9 and 16, the matrix 1 is interrogated by applying a zero to the respective vertical wires. In the position where the crosspoint is made the zero is transferred through digital switch 17 to a further digital switch 23 so that the informationon leads 8 is directly returned through leads 23 and the switching means 8 will respond to the memory output and provide pattern surface .control signals to the knitting machine needles. If the input to gating arrangement 23 is a 'one', then background colour information from keyboard 24 is sent through leads 23 to switching means 8. The control system is controlled by the sequence command device 29 which is not otherwise described.

Filed: 1975-04-15
Abstract: 1503812 Methanation reactions LUMMUS CO 15 April 1975 [8 May 1974] 15523/75 Heading C5E In a process for methanating a gas comprising carbon dioxide and hydrogen, the carbon dioxide is first separated from the gas and the resulting gas is passed to a methanation zone having at least two catalytic methanation stages, the separated carbon dioxide being introduced into the methanation stages in an amount which limits the temperature rise in each stage, without cooling, to at most 700‹ F. In the arrangement shown, a feed gas 10 comprising carbon monoxide, carbon dioxide, hydrogen, steam and methane is reacted in a shift converter 11 to give a gas 12 composed mainly of hydrogen, carbon monoxide and methane, this gas being passed through a primary carbon dioxide absorber 16 to give a gas 18 to be passed to the methanator 42, which has five stages. Carbon dioxide is recovered from the absorption solution in regenerator 24 and is divided into five streams 35a-35e to be fed into the methanation stages 42a-42e. The effluent 65 from the methanator is passed through a secondary carbon dioxide absorber 71, and the used absorption solution 22 is combined with that from the primary absorber to be fed to the regenerator. In the early stages of the methanation, e.g. stages 42a-42c, where carbon oxides are the rate-limiting components, their concentration is maintained at 7 mol. per cent or less. In the later stages, e.g. 42d-42e, where the hydrogen is rate-limiting, the carbon oxides concentration may rise to 6-10 mol per cent.

Abstract: 816,553. Gas turbine plant. LUCAS (INDUSTRIES) Ltd., J. May 23, 1957 [May 24, 1956], No. 16069/56. Class 110 (3). [Also in Group XXIX] In a gas turbine fuel control system including a variable delivery pump q in which pump output pressure acts on a piston y and atmospheric pressure on an evacuated capsule w to control a leak-off valve 4 carried on a pivoted lever u to control a servomotor piston 7 regulating the pump output, the compressor b driven by the turbine a and supplying air to the combustion chamber d also supplies air for a secondary purpose. The secondary air passes through a duct e controlled by a valve k interconnected with a valve m controlling a passage f connected to atmosphere and to a chamber s housing a diaphragm x connected to the lever u. With the valve m closed and the valve k open to supply secondary air, pressure builds up beneath the diaphragm to move the leak-off valve 4 towards closure so that the servomotor piston 7 moves to increase the pump output to its maximum value to automatically vary the air to fuel ratio to the combusion chamber. On the valve k being closed and the valve m opened, air from beneath the diaphragm escapes to the atmosphere so that the valve 4 opens wider to reduce the pump output. Intermediate rates of supply of fuel to the combustion chamber are obtained by varying the positions of the valves k, m relatively to their seatings. The piston y or an equivalent diaphragm instead of being subjected to pump output pressure may be subjected at its opposite sides to a pressure difference related to the rate of flow of fuel supplied by the pump. A spring- loaded control valve 14 may be provided between the pump and the combustion chamber.
