Title: New thiadiazoline sulphonamides and the preparation thereof
Filed: 1957-01-17
Abstract: The invention comprises compounds of the formula <FORM:0834285/IV (b)/1> wherein R1 is a hydrogen atom, an alkyl radical of 1-8 carbon atoms or a monocyclic aralkyl radical and R2 is a monocyclic substituted or unsubstituted aryl radical, the substituents being inert under the reaction conditions by which the compounds are prepared, and the process for the preparation of these compounds by chlorinating a 5-acylimino-4-mononucleararyl - substituted - D 2 - 1 : 3 : 4 - thiadiazoline-2benzylsulphide of the formula. <FORM:0834285/IV (b)/2> wherein Ph is phenyl to give the corresponding 2-sulphonyl chloride and reacting with ammonia to give the sulphonamide.  The chlorination is preferably carried out in an acidic medium such as glacial acetic acid at a temperature between 0 DEG  C. and 30 DEG  C. Suitable substituents on the aryl radical R2 include Cl, Br, I, NO2 and lower alkyl radicals.  Examples describe the preparation of the 4-phenyl-, 4-m-tolyl-, 4-p-chlorophenyl and 4-p-bromophenyl derivatives of 5 - acetylimino - D 2 - 1 : 3 : 4 - thiadiazoline-2sulphonamide.  Other specified products include 5-formylimino-, 5-propionylimino-, 5butyrylimino-, 5-valerylimino-, 5-phenacetylimino and 5-isobutyrylimino-derivatives of D 21 : 3: 4-thiadiazolines having as the 4-aryl substituent a phenyl-, p-iodophenyl-, p-acetamidophenyl-, m - methoxyphenyl-, 3 : 4 - dichlorophenyl- or p-isopropylphenyl group.  5 - Acylimino-4-aryl- D 2 - 1 : 3 : 4-thiadiazoline-2 benzyl sulphides of the second general formula above are made by reacting an acyl isothiocyanate such as acetyl thiocyanate with a benzyl 3-aryl dithiocarbazate of the formula R2NH.NH.CS.S.CH2Ph.

Title: Manufacture of ether derivatives of polyhydric alcohols
IPC: C11D19/00
Filed: 1938-01-22
Abstract: 500,765. Ethers and ether - esters. PROCTER & GAMBLE CO. Jan. 22, 1938, No. 2193. Convention date, July 9, 1937. [Class 2 (iii)] Ether-esters of polyhydric alcohols are made bv boiling a mixture containing a polyhydric alcohol, a carboxylic acid in amount insufficient to esterify all the hydroxyl groups, a mutual solvent for the acid and alcohol, a water entrainer of limited miscibility with water and sulphuric acid or a sulphonic acid, and distilling until the water expelled is more than that due to esterification. Instead of using a polyhydric alcohol and acid, a partial ester of the alcohol may be employed. If unesterified alcohol in excess of that necessary to form the partial ester is present, it becomes etherified with itself or with another alcohol such as a monohydric alcohol which may be present. Suitable water entrainers are benzene, toluene and xylene and a suitable mutual solvent is phenol. The ether-ester may be hydrolysed to obtain the ether. In examples there are employed : (1) stearic acid, glycerol, phenol, toluene, and sulphuric acid ; and (2) glycerol mono-oleate, glycerol, toluene, phenol, and sulphuric acid. In the second example, the product is saponified by heating with water in an autoclave or by boiling with caustic soda to saponify the ester groups, the product being polyglycerols.

Abstract: 524,121. Printing-processes; coating surfaces. INTERCHEMICAL CORPORATION. Jan. 23, 1939, No. 2283. Convention date, Feb. 9, 1938. [Class 100 (ii)] [Also in Groups III and IV] Set-off, preventing.-A wet film of film forming composition such as printing ink on paper, metal, cellulose and other surfaces, is rapidly set by incorporating into the wet film sufficient of a film-forming solid which is soluble therein to dry the film. Preferably the incorporation is effected by impregnating the wet film with a solution of the film-forming solid in a volatile solvent miscible with the film solvent. Thus, a slow drying linseed oil printing ink film may be rapidly set by spraying or over-printing with a 5 per cent. solution of high viscosity chlorinated rubber in toluol, or with solutions of rubber derivative resins, ester gum or other resins. A film ofprinting ink which normally dries by evaporation, such as a mixture of carbon black and a varnish consisting of rosin modified phenol aldehyde resin and petroleum, may be set by applying thereto a 2 per cent. solution of high viscosity ethyl cellulose in 50 per cent. toluol and 50 per cent. denatured alcohol. A nitrocellulose ink consisting of 4.1 parts of Hansa yellow toner, 19.2 parts of lemon cadmium yellow, 27.4 parts of titanium dioxide, 1.4 parts of glycol sebacate and 47.9 parts of nitrocellulose solution consisting of 10 per cent. of denatured alcohol, 23.3 per cent. of second nitrocellulose and 66.7 per cent. of butyl carbitol acetate may be set by spraying it with a 3 per cent. solution of 1,000 second nitrocellulose.

Abstract: 1495939 Measuring resistance EDGCUMBE PEEBLES Ltd 14 March 1975 [19 Jan 1974] 02618/74 Heading G1U A resistance meter having an ohm range, and a megohm range for insulation testing, the megohm range being of the type in which a high voltage, typically 500v, is applied across the insulation under test, is characterized in that in the megohm range the voltage applied to the insulation under test is varied with the resulting current that flows, the voltage being constant (at 500v) whilst the current is less than a first pre-set level, typically ¢mA, decreasing linearly towards zero as the current increases towards a second pre-set level, typically 1mA. In this way high currents which might cause danger are avoided and the load on the battery is reduced. In the ohm range a stabilized voltage in series with a resistor is applied across the resistance under test. As described the megohm range is selected by closing switches S1M, S2M, & S3M, Fig. 1. The output from an oscillator I1, I2, is then amplified I4, I5, I6, T3, transformed W and rectified D6, D7, and applied across test terminals TT1, (via a line X, potentiometer P2 and resistors R6 & R4) and TT2 (from the top of a resistor R17), and the voltage between terminal TT1 and the line X, resulting from current flow through the insulation under test, is amplified A5, A4, and indicated on a meter M. Whilst the current that flows through the insulation under test remains below ¢mA, the mark/space ratio of the oscillator output is controlled A3, T2, to maintain the rectified output voltage constant at about 500v, the reference signal for this control coming from a potentiometer P4 between the line X and a line stabilized, by a Zener Z and a control circuit A1, T1, a few volts below the line X. When the current through the insulation resistance rises above ¢mA, a break-point amplifier A2 begins to reduce the potential across a potentiometer P2 thereby causing the mark/space ratio of the oscillator output, and hence the voltage applied to the insulation under test, to be reduced. In the ohm range, switches S1, S2, S3 and S4 are closed, test terminals TT1 and TT2 in series with a potentiometer PO 1  are connected in parallel across a resistor R2, which is connected in series with a resistor R3 across the stabilized supply, and the potential across resistor R3 is amplified AS, A4 and indicated.
