Patent GB-356600-A (GB)
Title: Process for purifying lactic acid
IPC: C07C51/48
Filed: 1930-12-10
Abstract: Lactic acid obtained by fermentation is freed from impurities such as butyric acid, caproic acid and other higher fatty acids by treatment with volatile solvents in which lactic acid is insoluble.  Examples of such solvents are carbon disulphide and the chlorinated derivatives of methane and ethane, such as chloroform, ethylene dichloride, and carbon tetrachloride.  The solvent, after being shaken with the crude lactic acid in the cold, may be freed from the dissolved impurities by adding a neutralizing agent such as lime and separating the insoluble fatty acid salts thus formed.  The lactic acid may also be purified by a treatment with the vapour of the solvent in a process analogous to steam distillation, the acid being maintained at a temperature just above the boiling point of the solvent used.

IPC: B22F3/08
Filed: 1966-08-22
Abstract: 1,148,608. Moulding by shock waves. G. W. TUMM, and J. B. GUIN. 22 Aug., 1966 [20 Aug., 1965], No. 37489/66. Heading B5A. [Also in Divisions B3 and C7] A process and apparatus for sintering powders such as tungsten, tantalum carbide and carborundum and forming sintered bodies or coatings comprises suspending the powders in a liquid such as water or oil which is in contact with a mould, enclosing the suspension and mould in a container and subjecting the suspension to a series of successive shock waves. The suspension may be heated and agitated by rotation of the container which may itself be the mould. Alternatively a separate mould such as an article to be coated may be located in the container. The shock waves are produced either by spark discharge or by explosive charges in the liquid and the process may be a batch or continuous process. As shown in Fig. 1 the suspension of powder 12 in liquid 11 fills a container 1 lined with a ceramic layer 9 and 9a. Electrodes 5 produce a spark discharge in the liquid and the container is heated via 8. The particles form a sintered layer on the ceramic lining and is then stripped from the container. Further embodiments are described in which the container is rotated and in which the plane of rotation is also adjustable. The electrodes may be fitted with protective sheaths and are adjustable in position for changing the spark gap. Many different examples of the application of the process are given. A metal sheet placed in the container may be coated with a sintered layer (Fig. 6, not shown) and as shown in Fig. 6a a metal sheet 59 placed on a mould 62 may also be moulded into the required form at the same time as the sintered coating layer is formed. This application is of particular interest in the manufacture of the wings and fuselage of aircraft and for rockets. Gears, bearings and engine parts may also be coated and Fig. 7 shows a mould form 65 with a cavity 67 which is coated with a sintered layer. Beams, rails or rods may be coated with a sintered layer in a continuous process which also includes a pre-stressing of the rail (Figs. 8-10, not shown). Sintered layers may also be formed on the teeth of a rotary saw which rotates in the sintering chamber containing the suspension (Fig. 13, not shown).

The core is mounted on a support that defines a longitudinal slit in the article. As described, the mould halves 3 are supported by rolls 4 and fillets 5 on a pair of endless horizontal chains 1 (see Fig. 1, plan view). One fillet for each mould half pair is supported by a spring 8 that presses the halves together when adjacent. A vertical chain 9 (Fig. 3) supports core members 10 hung on bridges 11. A sheet 12 (Fig. 1) is bent to form the sheath, and its edges and the bridges 11 clamped in the parting line of the mould halves. A metering device 15 feeds foaming material into the sheath as the mould halves close together, and as they open at the end of the moulding run, wedges 16, 17 open the slit, hollow article to allow the core members to be extracted. The core chain 9 is driven independently or by the mould halves, and each core member supports a fillet 18 (Fig. 3) that moulds a hinge in the article. The core members are centred together by pins and magnets, and, together with the mould halves, are interchangeable to allow the cross-section of the article (e.g. an insulation sleeve for a radiator pipe) to vary along its length.

Abstract: 635,566. Icing indicator. GROUPEMENT FRANCAIS POUR LE DEVELOPPEMENT DES RECHERCHES AERONAUTIQUES. Dec. 30, 1946, No. 38067. Convention date, Dec. 31, 1945. [Class 4] An ice formation detector, particularly for aircraft, comprises a feeler 7, which is made to sweep the surface S to be scanned and the blocking of the feeler is used to indicate the presence of an ice-layer. To make the feeler 7 sweep the surface, impulses are applied to an electromagnet 1 which attracts an armature 2 carried by a pivoted shaft 3 against the action of a coiled spring 4. These impulses are applied through a further coiled spring 5 to coaxial shaft 6 carrying the feeler 7. If no ice is present feeler 7 is not obstructed, but if ice prevents the movement, contacts 8, 9 carried by shafts 3, 6 respectively are closed, thereby actuating a relay switch 11, 16 to energize a warning signal 18 or a de-icing resistance 17 or other devices connected to the terminals 19 in Fig. 2. A further relay switch 11, 15 ensures that when the feeler is blocked the electromagnet 1 is constantly energized. In a modification, there is only a single shaft coupling the armature 2 to the feeler 7 and the circuits include a time base relay which operates a warning device in the event of the feeler not completing its cycle of movement within a certain period.

Abstract: 931,769. Measuring deformation. AMETEK Inc. Nov. 10, 1959 [Nov. 10, 1958], No. 38156/59. Class 40 (1). [Also in Groups XIX and XXIV] For measuring the strain of a stressed specimen in a sealed enclosure (e.g. containing gas or vacuum at a high temperature), the specimen is coupled to a slug of magnetic material movable within a housing attached to the enclosure, and a coil is provided outside the housing adjustable relative to the slug, so that strain in the specimen moves the slug and changes the output signal from the coil. The specimen 7 to be tested (Fig. 1), is fitted with spaced clamps 13 and 14 to which are attached links 15, 16 for transmitting the motion to yokes 17, 18. These in turn (Fig. 4) are joined to levers 25, 28, pivoted at 27, 29 respectively and connected by flexible strips 54, 46 to a further lever 42, which then moves a bar 43 when deformation of the specimen produces a change in the separation of the yokes 17, 18. The bar 43 causes a fourth lever 40 to rock about its pivot 41 and move the arm 62 which is attached to the armature 68 of a differential transformer (Fig. 3). All the parts so far described are in the same sealed container as the specimen, but the coils 76, 77 of the transformer lie outside the container, the walls of which here comprise a tube 69 of glass or other non-magnetic material. Zero adjustment of the electrical output of the transformer is effected by rotating a worm 85 which engages a worm wheel 83 fastened to a nut 80. The latter co-operates with a thread on the outside of the assembly 78 which holds the coils and moves them axially with respect to the armature against a spring 82.

A method of generating steam at subcritical or supercritical pressures involves introducing feedwater into a circulating stream of steam at a point where the steam is superheated, thereby evaporating the feedwater to produce a combined stream of steam which is at least at saturation temperature. A quantity of this steam, generally corresponding to the amount of feedwater introduced is withdrawn and superheated and conveyed to the point of use, the remaining circulating steam being compressed and resuperheated and the cycle repeated. Steam circulates in the system denoted by numeral 16, being compressed by a compressor 18 and superheated in parallelconnected tubes 20 of which there may be a large number and which are disposed in fire chamber 10. Feedwater supplied by pump 66 is preheated at 30 and is introduced into the stream of steam by temperature controlled spray means 34 and 36 at locations in tubes 20 such that at least some of the water is introduced after the steam has traversed the full length of superheater tubes 20. Steam is withdrawn at point 38, the remaining circulating steam passing to the compressor inlet to repeat the cycle. The withdrawn steam is superheated in low, intermediate and high temperature portions 40, 42 and 44 respectively of a superheater unit also disposed in chamber 10, and passes to the point of use which as shown comprises turbines 48 and 54 having an interstage reheater 52. Final temperature control of the steam passing to the turbines is provided by spray-type desuperheaters 50 and 58 respectively.
