The Zond VD - 96 portable eddy-current flaw detector-tester is an original Russian development possessing heightened sensitivity for the surface defects and high inspection capacity. (Russia patent Xs 2063025. All-Union state standard certificate of Russian Federation JVa 2846 of 14. 07. 97)... 

Commercial interest in PVC also commenced at about this time. The Russian, I. Ostromislensky, had patented the polymerisation of vinyl chloride and related substances in 1912, but the high decomposition rate at processing temperatures proved an insurmountable problem for over 15 years. Today PVC is one of the two largest tonnage plastics materials, the other being polyethylene.

The major potential uses of wastes in cementing technology are summarized in Table 10-16. There are many Russian patents dealing with the use of wastes from the production of organic chemicals as cement additives. 

A frost-resistant formulation from a Russian patent [147] is given in Table 17-19. The composition has a frost resistance down to —35° to —45° C. 

The fact that a given company has changed its name during the considered development has been taken into account and all those patents are discussed together. Some difficulties were found with Asian (Chinese or Korean) and European (Rumanian, Russian, etc.) patents, particularly those which do not have a published or any English equivalent. 

He discovered microorganisms, which have the capability for working in situ, anaerobically, in the well. These discovered microorganisms seem to decrease S and N content from oil and convert also H2S, resulting of potential interest for both, gas and oil wells. Unfortunately, both of his patents are in Russian and only the abstract is accessible. 

The second patent [139], also in Russian, with only an English abstract, regards a microbiological conversion method, which results in an enrichment on isoparaffin and aromatic hydrocarbons of the petroleum products. It also states an unclear fact of simultaneously removing inhibitory additives . The abstract specifies the nature of...

Indole. Russian patent 306, 126 (1971). Note See the making precursors section of this book for an explicit method of producing methylindole in good yield. Add 26 ml of 0.77 N NaOCl to a stirred suspension of 1.9 g of orthocarbamoyl cinnamamide in 50 ml of methanol and heat in a distillation apparatus until no more indoles is distilled off (use an indole test) or just heat at 40° for 2 hours. Extract the distillate with chloroform, dry with most any drying agent, except calcium chloride, and evaporate the solvent (CHCb) off from the remaining indole. Yield 45%. 

The currently accepted name for (1) in Chemical Abstracts is dibenzothiophene, although biphenylene, diphenylene, or biphenylylene sulfide are still used, especially in the Russian literature. Occasionally 9-thia-fluorene is used and recently, in one instance, dibenzo[6,d]thiophene. An alternative numbering system for (1) is met with on occasions in which C-4 is taken as C-1, as in carbazole. In the absenee of moleeular diagrams this system must be detected by reference to the chemistry described. For example, in a few dyestuff patents 2,7-diaminodibenzothiophene 5,5-dioxide is referred to and this is obviously the 3,7-diamino compound, also known as benzidine sulfone. 

Another novel type of electrochemical fluorination unit, incorporation a metal electrolyser lined with teflon, capable of both bipolar and monopolar function is claimed in a Russian patent [139] to have advantages in simplicity of assembly and operation. 

A filter press arrangement incorporating perforated bipolar electrodes to allow flow channels is described in another Russian patent [140].
