Title: Manufacture of organic arsenic and antimony compounds
IPC: C07F9/00
Filed: 1929-10-18
Abstract: Organo arsenic and antimony compounds are prepared by exchanging in known manner the hydroxyl group for X in compounds of the formula Y.Ar.NH.CO.(CH2)n.X, in which Y represents a residue containing arsenic or antimony in a tri- or penta-valent form, X signifies an amino group or a halogen atom, Ar stands for a substituted or unsubstituted aryl residue (but when X is halogen, Ar must not contain a hydroxyl group in orthoposition to the halogen-acylamino group), and n is an integer.  According to the examples, (1) arsanilic acid is treated with chloracetyl chloride and then with caustic soda to give p-glycollylaminophenylarsinic acid; the same product is obtained by treating the chloracetylarsanilic acid with ammonia and decomposing the resulting glycylarsanilic acid with sodium nitrite in the presence of hydrochloric acid; (2) p-glycollylaminophenylarsenoxide is formed when p-aminophenylarsenoxide is acylated with chloracetyl chloride and the product heated with caustic soda; (3) 3-methyl-4-aminophenylarsinic acid is treated first with chloracetyl chloride and then with ammonia, and the 3-methyl-4-glycylaminophenylarsinic acid is then decomposed with nitrous acid to give 3-methyl-4-glycollylaminophenylarsinic acid; (4) p-glycollylaminophenylstibinic acid is produced when the product of interaction of p-aminophenylstibinic acid and chloracetyl chloride is boiled with caustic soda solution; (5) 2-methyl-4-aminophenylarsinic acid is treated with chloracetyl chloride or a -bromopropionyl bromide and the resulting compound decomposed with caustic soda; the product comprises 2-methyl-4-glycollylaminophenylarsinic acid and 2-methyl-4-lactylaminophenylarsinic acid respectively.  The Specification as open to inspection under Sect. 91 (3) (a) also states that X may represent an acid residue, and contains Examples according to which 2-hydroxy-4-aminophenylarsinic acid, 4-methoxy-3-aminophenylarsinic acid and 2:5-dimethyl-4-aminophenylarsinic acid are treated with chloracetyl chloride and the products heated with caustic soda solution to give the corresponding glycollylamino compounds.

Title: Process for the manufacture of insulating materials
IPC: H01B3/18
Filed: 1932-11-10
Abstract: Insulating material is manufactured by exposing a chlorodiphenyl which is liquid at room temperature, obtainable by chlorinating diphenyl in any desired manner, and preferably containing 40 to 60 per cent of chlorine, to an electrical high tension field until disruptive discharge has occurred and purifying the product by distillation at normal or reduced pressure, or by filtration, for example through Florida earth. The product can, if necessary, be subjected to a neutralization process.  In this manner the disruptive strength of the chlorodiphenyls is increased up to at least 150 KV/cm and in most cases to about 160 KV/cm.  An example shows the effect of the process on the disruptive strength of a chlorodiphenyl of 55--56 per cent chlorine content.  The Specification as open to inspection under Sect. 91 comprises also the use of the products in admixture with other insulating materials, e.g. chlorinated hydrocarbons such as polychlorinated benzenes or naphthalenes.  The products are stated to be suitable for use in electrical transformers.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to start-stop telegraph systems
IPC: H04L12/26
Filed: 1961-09-07
Abstract: 913,981. Distortion of telegraph signals; measuring. SIEMENS & HALSKE A.G. Sept. 7, 1961 [Sept. 7, 1960], No. 32221/61. Class 40 (3). In a circuit for measuring the distortion of telegraph signals, the signal pulses are sampled at the nominal pulse centres referred to the beginning of the start pulse in order to produce a distortion-free signal, the incoming telegraph signals are delayed by half a pulse period and the distortion-free signals and the delayed signals are supplied to a comparator which determines the time interval between corresponding pulse reversals in the two signals. In the embodiment described, the largest value of the distortion which occurs over a given period is recorded.  Circuit details.-The incoming telegraph signals are applied at E to a bi-stable circuit K1 which switches to the Z state on arrival of a start pulse and opens gate G1 whereupon a reset voltage is removed from counters Z1, Z2 which then start to count the 20 kc/s. pulses from oscillator TG. After 10, 30, 50 ... m/sec. the output b of Z2 opens G5, G6 to register the input pulse in K4 the output of which represents the distortion-free signal. K5 is initially in state T so that pulses on the output a of Z1 are passed by G2 to counter Z4 which produces an output pulse 10 m/sec.s later to open G7, G8, whereupon the state of K1 is transferred to K5 and gates G2, G3 are closed until the next pulse reversal alters the state of K1. The output of K5 is thus the input signal delayed by half a pulse period. Gates G9 or G10 is opened when K4 and K5 are in different states so that pulses on output b of Z1 are passed to G11, G12 and counter K9-K15. The state of K6 is continuously reversed by the outputs a, b of Z2 so as to activate G11, G12 alternately during the periods corresponding to leading and lagging distortion respectively. Stores KV9-KV15 and KN9-KN15 register the highest percentage leading and lagging distortion to have occurred previously. The pulses supplied from G9 or G10, representing in number the percentage distortion of a signal pulse being measured, step on counter K9-K15. If the count thus registered becomes equal to that registered in the appropriate store, all gates VGV9-VGV15 or VGV9-VGN15 are closed, K7 is reset to the O state and G11 or G12 is opened to pass any further pulses from G9 or G10 so as to increase the count stored. The counter K9-K15 is reset by the output a of Z2, i.e. at the pulse-centres of the distortionfree signals. The numbers stored in KV9- KV15 and KN9-KN15 in binary code are converted to decimal code and operate indicators such as lamps LV1, LV10 and LN1, LN10. After 140 m/secs. counter Z3 resets K2, Z1, Z2, K4, K5 until the next start pulse arrives at E. The period over which distortion measurement takes place is determined by monostable circuit KM or manually-operated switches T1, T2.

Title: New active substances and process for their manufacture

Abstract: The invention comprises ferrirhodin and desferrirhodin which are obtained by cultivating Aspergillus versicolour M3636 or Aspergillus nidulaus M2734 under aerobic conditions in an aqueous nutrient medium containing a source of nitrogen and carbon and inorganic salts. Preferably the medium has an iron content of less than 10-7 mol./litre.  The material may be recovered by adsorption, solvent extraction or chromatography.  Ferrirhodin may be converted to desferrirhodin by reaction with an acid or base or an iron complex-forming substance, e.g. 8-hydroxyquinoline, and ferrirhodin is reformed by adding iron ions to desferrirhodin. Ferrirhodin may be catalytically hydrogenated to hexahydroferrirhodin, iron removed to form desferrihexahydroferrirhodin, deacylated by mild acid hydrolysis, acetylated and the O-acetyl groups split off to obtain desferrichysin, which may be converted to ferrichrysin with a ferric salt.  Examples are given.  Pharmaceutical preparations contain ferrirhodin, desferrirhodin or hydrogenation products thereof, together with carriers, e.g. gelatine, lactose, glucose, sodium chloride, starches, magnesium stearate, talc, vegetable oils, benzyl alcohol, gums, polyalkylene glycols and cholesterol.
