Title: Pure racemic tartaric acid and meso tartaric acid - prepn. from maleic acid in presence of alkali tungstates or molybdates as catalyst
IPC: C07C51/47
Filed: 1976-02-25
Abstract: Pure racemic tartaric acid and meso- tartaric acid are prepd. by reacting alkali moleatis with H2O2 in aqs. soln. in the presence of catalysts. In this process, the mol. ratio of H2O2 to moleic acid is >1 and the alkali salts formed from cis-epoxysuccinic acid and the alkali tungstate and/or molybdate, opt. after distruction of excess H2O2 are converted into free cis-epoxysuccinic acid and into free tungstic and/or molybdic acid by passage over a strongly acid cation exchanger. The free cis-epoxysuccinic acid is then hydrolysed, in the presence or absence of free tungstic and or molybdic acid to obtain racemic tartaric acid and meso-tartaric acid. The tungstic and or molybdic acids are eliminated on anionic exchangers before the hydrolysis if this is effected in the absence of a catalyst or after the hydrolysis if this is effected in presence of a catalyst. The racemic tartaric acid is then crystallised in known manner from the hydrolysis mixture free soln. tungstic and or molybdic acids, opt. by evaporation of water and reduction in temp. The meso-tartaric acid remaining in the mother-liquor is recovered by crystallisation or by evapn. to dryners, opt. mixed with tartaric acid and unreacted cis-epoxysuccinic acid and mallic acid. The anionic exchanger charged with tungstic and/or molybdic acid is regenerated in known manner with dil. alkali and the soln. of alkali tungstates and/or molybdatic obtained in opt. recycled, after an opt. opt. treatment with active C, directly to the epoxidation stage. The racemic tartaric acid is obtained in very high yield and purity, suitable for foodstuffs. The catalyst is recovered simultaneously, and the presence or absence of the tungstic, molybdic or mixed catalyst influences the proportion of meso-tartaric acid which is formed.

Patent FR-2339831-A1 (FR)
IPC: F28F13/02
Filed: 1977-01-26
Abstract: Hydrophobic substances which are active at the interface are dosed into the heat-dissipating and/or heat-absorbing medium of a surface heat exchanger. The dosing is performed in such a quantity that and over such a time interval that a thin hydrophobic film is formed. Dosing of the materials which are active at the interface is performed, e.g. in the vapour upstream of a condenser (5). It can be performed periodically or continuously. The dosing solution is prepared in an add-on container (1) having a volume of approximately 1 m<3>. A dosing pump (2) is used to dose the solution into the vapour line (4) via pipeline (3). If desired, a dosing probe can be installed in the vapour line (4). A thin hydrophobic film forms in the condenser (5) on the heat exchange surface. This film prevents the material from being attacked by the condensate, and prevents the formation of water boundary films on the heat exchange surface. Because the surfaces thus rendered hydrophobic cannot be wetted, the vapour can condense only in the form of drops. This results in an intensive improvement of the heat transfer.

Title: Texturing yarns at high speed - with obstruction abruptly stopping motion of yarn adhering to cylindrical support surface
Inventor: MAEKAWA KAZUYOSHI
IPC: D02G1/00
Filed: 1977-02-22
Abstract: Yarns are textured by being accelerated to a predetermined speed and then at a point along their path being abruptly stopped. The yarns are made to adhere to the surface of a rotating cylinder and allowed to run up against an obstruction positioned very close to the cylindrical mantle, in the manner of a doctor blade, so that when they strike this, the filaments are crimped. Alternatively, the obstruction may be used to build up the yarn with the upstream face of the wad forming the stoppage and crimping the yarn. Method cuts out the disadvantages of stuffing boxes with their slower speeds, quick wearing of components entailing stoppages for replacements, etc. A wide range of different yarns can be processed at very high working speeds on a machine of simple and compact design. The yarn to be textured can be fanned out without the need for bundling of the filaments to a precise density in the tow.
