Experimental disinfection in salmonellosis abortions in sheep. Iovchev, E. (Vet. Inst. Zarazni Parazit. Bolesti, Sofia, Bulg.). Salmonelite Salmonelozite Bulg., Nats. Konf., 2nd, Meeting Date 1971, 297-300. Edited by: Bratanov, K. Izd. BAN: Sofia, Bulg. 7778-54-3 and 60569-86-0 are also in the experiment. (Bulgarian) 1974. CODEN: 34YOAT. DOCUMENT TYPE: Conference CA Section: 5 (Agrochemicals) Salmonella abortusovis-infected manure litter in a sheep stable was disinfected 8 h after treatment with lime chloride [7778-54-3] (200 g/m2) activated with an aq. soln. of calcium superphosphate [7758-23-8]. Disinfection was also obsd. 12 h after combined treatment with the lime chloride powder (200 g/m2) and virusan [60569-86-0] (100 g/m2). .

Inhibition of stress-corrosion cracking of steel pipeline

Inhibition of stress-corrosion cracking of steel pipeline. Fessler, Raymond R.; Berry, Warren E.; Wenk, Russell L.; Parkins, Redvers N.Several substances are used for example 6484-52-2 and 7758-29-4 which are their cas registry numbers. (American Gas Association, USA). U.S. US 3973056 3 Aug 1976, 15 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: F16L058-04. NCL: 427136000. APPLICATION: US 74-477169 6 Jun 1974. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) The inhibition of stress-corrosion cracking of pressurized X-52 [39362-66-8] steel pipelines for gas transmission is accomplished by use of 0.1-1% Ca(H2PO4)2 [7758-23-8], NaH2PO4 [7558-80-7], Na5P3O10 [7758-29-4], or aq. K silicate [1312-76-1] (K2O 9, SiO2 20, H2O 71%). Concns. of 0.01-1% were tested in solns. contg. 33% NaOH, 20% NH4NO3, and N NaCO3 + N NaHCO3. Range in NaOH and Na2CO3-NaHCO3 solns. and at -175 mV (Cu-CuSO4) in a NH4NO3 soln. These solns. were chosen because field and lab. tests have shown that stress-corrosion cracking of buried pipelines is caused .gtoreq.1 of these chem. in the environment. Liqs. contg. CO3, HCO3, OH, Cl, and/or NO3 ions were found under coatings near stress corrosion cracks in pipelines buried in 4 different states of the US. In general, the best results were obtained with 1% Ca(H2PO4)2.H2O and Na5P3O10 solns. Inhibiting compns. for coating pipelines were prepd. by blending 20% of each of the inhibitors with a coal tar primer, but the K silicate compn. formed a gel that did not harden. Teaching times and failure times were detd. for each compn. Other methods of application involve incorporation into asphalt and epoxy resins. In coal tar and these media, baking would be required, hence coated specimens were baked at 500.degree.F for 1 hr. The results indicated that Na5P3O10 was least likely to be affected by baking. .
