Title: Process for the production of 1,1,2,2-tetrachloroethane
Inventor: SUZUKI AKIRA
IPC: C07C17/04
Filed: 1966-03-01
Abstract: 1,1,2,2-Tetrachloroethane is prepared by chlorination of anhydrous vinyl chloride or anhydrous 1,1,2-trichloroethane in the liquid phase by blowing thereinto molecular chlorine at 90-140 DEG  C. in the presence of anhydrous aluminium chloride as catalyst, using an amount of chlorine sufficient to allow the HCl gas generated in the reaction to contain at least 2 mol per cent of unreacted chlorine, based on the molar quantity of the blown chlorine.  The catalyst may be made in situ by adding metallic aluminium to the reaction mixture which may contain a non-aqueous solvent.  It is preferred to use sufficient chlorine to provide a 10-20 mol per cent excess in the exit gases. Small amounts of penta- and hexa-chloroethane may be formed as by-products. 1,1,2,2-Tetrachloroethane may be isolated from the reaction mixture by distillation, optionally after washing with water or aqueous hydrochloric acid. Examples are provided.

Title: Improvements in the continuous coating of bands with synthetic material
IPC: B05C3/12
Filed: 1963-03-07
Abstract: 1,014,835. Web coating apparatus. SCHLOEMANN A. G. March 7, 1963 [April 4, 1962], No. 9070/63. Heading D1L. In a method of applying thin bubble-free coatings of synthetic material in a liquid or pasty condition, in a continuous operation to continuously moving bands and of rapidly hardening the coating, the synthetic material is brought into a pasty to liquid condition by means of a solvent prior to being applied and the applying and the subsequent hardening or polymerization of the coating are carried out in a vacuum. The apparatus illustrated consists of two sealing vessels 1 and 4 having therebetween two treatment vessels 2 and 3, a vacuum tank 5 arranged above and six vertically extending connecting tubes 6, 7, 8, 9, 10, 11 connecting the vessels to the vacuum tank in such a way that a band 12 to be coated can be passed through the apparatus in a succession of vertical loops by way of reversing rollers 13, 14, 15, 16, 17, 18, 19. Actual coating devices 26, 28 and 25, 27 are provided in the treatment vessels and the vacuum tank respectively. In operation band 12 to be coated is introduced into the apparatus via entry roller 20 and is guided upwards by reversing roller 13 into tube 6. In the upper part of tank 6 is a heating device 32 which dries the band after which the latter passes round roller 17 where an adhesion-promoting medium is applied to one side of the band by coating device 25. The band then travels into tube 7 where the coating is irradiated by heating device 32. The band then passes into vessel 2 and around roller 14 where an adhesion-promoting medium is applied to the other side of the band. The band then proceeds into tube 8 where it is again dried by a heating device 32. From tube 8 the band passes around roller 18 where the first side of the band is coated by apparatus 27 with a synthetic material which during further travel of the band through tube 9 is hardened or polymerized by a heating device 32. Then in the treatment vessel 3 the coating of the second side of the band with synthetic material is effected as it passes around roller 15 by coating apparatus 28 and this is followed by hardening or polymerization in tube 10. The band is then deflected downwards again by roller 19 into the seal vessel 4 and thence out of the apparatus via roller 21. Further heating devices may be provided immediately prior to coating appliances 27, 28 to soften the adhesion-promoting coating to give a better adhesion for the layer of synthetic material. The liquid in sealing vessels 1 and 4 may also serve for treatment of the band e.g. the solution in vessel 1 may be a cleaning fluid and that in vessel 4 may provide a protective film on the band.

Abstract: 1518583 Sealing VSES TEPLOTEKHNICHE NI INST IM FE DZERZHIN 10 March 1976 09587/76 Heading F2B A sealing means, for sealing an annular gap between two components which may be fixed or rotate relative to one another, the annular gap operating media at different pressures, comprises a liquid sealant 4 and, in a recess 6 concentric with the gap 3, a fine-grained packing 5 which is compressed in the recess, has a polycapillary structure and is resistant to wetting by the sealant 4. The resistance to wetting ensures that the sealant 4 in the capillaries has a very high surface tension which opposes the pressure p 1  of the medium to be sealed. In the embodiment shown in Fig. 1, the seal is between a pair of flanges, on the left-hand side of the figure the higher pressure p 1  being on the outside and acting on the surface of sealant 4, and on the right-hand side the higher pressure p 1  being on the inside. The sealing liquid 4 may be the medium sealed (Figs. 2 and 3, not shown). The fineness of the grain of the packing 5 may increase from the low pressure side to the high pressure side. In the embodiment shown in Fig. 6 the sealant 4 is separated from the packing 5 and communicates with it through the gap 3, the packing 5 being held compressed in its recess 6 rather than compressed by the pressure p 1  as in the embodiment of Fig. 1. Teeth 14 of an annular projection 7 maintain sealing should the sealed members 1 and 2 move slightly apart. There may be packing 5 on each side of sealant 4 (Figs. 4 and 7, not shown). A seal for a horizontal rotating shaft 29 in a housing 30 enclosing the higher pressure p 1  is shown in Fig. 9. Sealant 4 is disposed in a chamber surrounding the shaft and is restrained from rotating with the shaft by ribs formed by notches 31 in a bush 26, the bush 26 being between rings 24 which compress the packing 5 in spaces 6 and 6a. The pressure p 1  is communicated to the surface of sealant 4 on one side of a flange 32 through an aperture 34. A liquid 36 which is capable of wetting the packing 5 and also acts as a lubricant is received in an annular reservoir 35 and pumped by a pump 39 ta the right-hand portion of seal 4. The pump 39 is switched on by a sensor 44 of the level 41. An embodiment for a vertical shaft is also described (Fig. 10, not shown). The packing 5 may be graphite powder and the sealant 4 can be of molten tin or molten Wood's alloy and may contain bronze powder to increase the surface tension. Water can also be used with graphite.
