Title: Anti-oxidants for petroleum hydrocarbon oils
IPC: C10M159/12
Filed: 1944-12-12
Abstract: The unsaturated compound-sulphur halide-aromatic compound complexes of Specification 591,714, which have been reacted with a combination of the elements phosphorus and sulphur according to Specification 591,717, are converted to their salts before being incorporated in a petroleum hydrocarbon as corrosion inhibitors. The conversion to a salt may be effected by reaction with a metal, metal oxide, metal hydroxide or other suitable metal compound or with a suitable non-metallic base.  Salts of non-metallic bases which may be prepared are onium salts such as ammonium, alkylammonium, quarternary ammonium, sulphonium and phosphonium salts, amine salts and salts of other organic bases.  If desired, the reaction of the unsaturated compound-sulphur halide-aromatic compound complex with the combination of the elements phosphorus and sulphur, and the conversion to a salt may be conducted simultaneously, for example by reacting the complex with a mixture of phosphorus sulphide and metal oxide.  The petroleum hydrocarbon composition may be any of those mentioned in Specification 591,714 and may contain any of the additional ingredients mentioned in that Specification.  In an example, a diisobutylene-S2CI2-phenol complex is reacted with P2S5, the product converted to its salt by reaction with zinc oxide and the salt blended with mineral lubricating oil.ALSO:The unsaturated compound-sulphur halidearomatic compound additives of Specification 591,714, which have been reacted with a combination of the elements phosphorus and sulphur according to Specification 591,717, are converted to their salts before use.

Abstract: 809,701. Rolling. SCHLOEMANN A.G. Aug. 21, 1956 [Aug. 22, 1955], No. 25493/56. Class 83 (4). In a method of continuous rolling in which loops are formed between the stands and controlled in size by varying the roll speeds, guides form initial loops of medium size and the speeds of the roll stands are initially set according to the speed and elongation in preceding stands.

Title: Improvements in devices for comparing an electrical frequency with a reference frequency
IPC: G01R23/02
Filed: 1957-08-13
Abstract: 855,426. Frequency discriminators. ELECTRICITE DE FRANCE, SERVICE NATIONAL. Aug. 13,1957 [Aug. 23,1956], No. 25578/57. Class 40(5). [Also in Group XXXVI] In an electrical frequency comparator, a reference frequency f o  is compared with an incoming frequency, f to produce an error frequency #f in the form of an electrical output voltage, which controls the value of #f such that f o  + #f = f thereby permitting measurement of #f. The reference voltage of frequency f o , determined by a quartz oscillator (not shown) is applied to two phase shift networks 2, the resultant three phase voltage being fed to the stator windings 3 of a selsyn, the rotor output of which is applied from winding 4 between the grid and cathode of a thyratron 1. The phase of the output voltage of the selsyn with respect to the input voltage, varies in correspondence with the change in the angle of the axis of the rotor. Thus when the rotor is driven at #f revolutions per sec. the output voltage has a frequency of f o  Œ #f. The voltage of frequency f is applied to the plate of a thyratron 1. Thus the difference between f and f o  + #f, varies the mean current i delivered by the thyratron, which current, in turn, controls the rotation of rotor 4. A D.C. motor 5, whose shaft is connected to rotor 4, is fed with current i, and with a current i<SP>1</SP>, in opposition to current i, derived from source f by rectifier 6. A potentiometer 7 is adjusted so that the mean values of currents i, i<SP>1</SP> are equal when f = f o . The speed of rotation of rotor 4, which tends to equal #f = f# f o  is measured by a tachometer winding 8 mounted on the shaft of rotor 4. A revolution counter mounted on the same shaft indicates the integral of the frequency #f and hence the phase .difference between the two voltages.
