[Class 39 (i).] Wire or strip-shaped auxiliary electrodes 8, 9 are arranged longitudinally inside the tube 1 and are connected to an auxiliary source of current 14 having a voltage higher than that of the source 16 to which the main electrodes 4, 5 are connected. The resistances 11, 12 may be each of 1000 to 10000 ohms. The electrodes 4, 5 may be oxide-coated filaments heated from the secondaries 17, 18 of a transformer the primary of which is connected to the supply 16. Leads 19, 20 connected to the centres of secondaries 17, 18 supply the main discharge current and an impedance 21 may be included. The auxiliary electrodes may be spaced and supported by a glass bead 10, or may overlap, preferably for less than one-third of the tube length. Parts of the auxiliary electrodes in the neighbourhood of the main electrodes may be encased in protecting tubes of porcelain, and a gauze grid, supported from the walls of the tube, may surround the centre 10 to prevent blackening of the tube. The connections are preferably arranged so that when the electrode 4 is negative, the auxiliary electrode 8 is positive. More than one pair of auxiliary electrodes may be provided. A cylindrical anode may surround each incandescent electrode and be connected to it, so that on the half-wave when the latter is positive this anode may receive the current. An example is cited in which a tube 1 metre long having a diameter of 40 mm. and a neon filling at a pressure of 1À8 mm. was started with a voltage of 180-190 volts. the voltage of the secondary winding 13 being then 360 volts.

Title: Manufacture of iodinated esters
IPC: C07D213/68
Filed: 1938-07-25
Abstract: 517,382. Iodinated esters. BRANSCOMBE, D. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 25, 1938, No. 22090. [Class 2 (iii)] New iodinated esters are manufactured by causing a saturated or unsaturated aliphatic alcohol containing at least three carbon atoms to react with a mono- or poly-iodo aromatic or heterocyclic carboxylic acid or the acid halide thereof, or by causing a halogen ester of the alcohol to react with a neutral salt of the acid. When the reaction is between the acid and the alcohol, it is carried out in the presence of a dehydrating catalyst, e.g. hydrochloric acid or sulphuric acid. In each case the reaction is brought about by heating the reagents together, if desired in the presence of a solvent, for example benzene or xylene. Acids mentioned as starting materials are mono- and poly-iodo-benzoic acids, e.g. 2-iodobenzoic acid, 2:5 or 3:5-di-iodobenzoic acid, 2:3:5 or 3:4:5- tri-iodobenzoic acid and also acids containing substituents additional to the iodine atoms, for example amino, hydroxy or alkoxy groups and heterocyclic carboxylic acids such as mono- and di-iodohydroxypyridene carboxylic acids. Suitable alcohols and halogen esters mentioned are propanol, isopropanol, butanol, dodecanol, octadecanol, allyl alcohol and octadecenol and the corresponding chlorides or bromides. The products are useful as X-ray contrast agents for diagnostic purposes. In the examples (1) 2:5-di-iodobenzoyl chloride is condensed with octadecenol ; (2) 2:3:5-tri-iodobenzoyl chloride is condensed with (a) octadecenol and (b) dodecyl alcohol; (3) 2-iodobenzoyl chloride is condensed with allyl alcohol ; (4) 2:5-di-iodobenzoic acid is condensed with propanol; (5) 3:5-di-iodo-4-pyridone-N-acetic acid is condensed with (a) n-butanol, (b) isopropanol and (c) octadecenol, in the presence of sulphuric acid ; (6) 3:5-di-iodo-4-methoxyphenylacetic acid (prepared by diazotising 4-carboxymethyl- 2:6-di-iodoaniline, 'converting the diazo compound into the corresponding phenol and methylating this with dimethyl sulphate and alkali), is condensed with isopropanol in the presence of sulphuric acid ; (7) 3:5-di-iodo-4-aminophenyl-acetic acid (prepared by treating 4- aminophenyl-acetic acid with iodine and alkali or with iodine monochloride and hydrochloric acid) is condensed with isopropanol in the presence of sulphuric acid ; (8) 3:4:5-tri-iodophenacetyl chloride (made by treating diazotised 4-carboxymethyl-2:6-di-iodo-aniline with potassium iodate and heating the product with thioryl chloride) is condensed with octadecenol ; (9) silver 2:5-di-iodobenzoate is condensed with isopropylbromide and (10) silver tetra-io.dophthalic acid is condensed with (a) octadecenyl bromide and (b) dodecyl bromide.

Title: Process for the production of low molecular weight polyolefins
IPC: C08F10/00
Filed: 1957-07-12
Abstract: Low molecular weight polyolefins, e.g. polyethylene of m. wt 50,000-100,000, are produced by polymerizing olefins in a liquid hydrocarbon medium at a pressure below 100 kg/sq. cm. and a temperature below 100 DEG  C. with a catalyst consisting of titanium trichloride and dialkyl aluminium monochloride in a mol. ratio of at least 2: 1, the concentration of impurities being such that decomposition of aluminium dialkyl monochloride is kept to a minimum. The polymerization may be operated batchwise or continuously, i.e. including continuous catalyst addition, and in the latter case to avoid the build-up of higher concentrations of the aluminium component of the catalyst the liquid medium may be continuously withdrawn and replaced.  The titanium trichloride may be prepared from titanium tetrachloride by reduction with diethyl aluminium chloride in a hydrocarbon medium and under purified nitrogen.  The aluminium catalyst component may be the diethyl chloride.ALSO:Titanium trichloride is made by the reduction of the tetrachloride with aluminium diethyl chloride, and details are given of conditions of temperature, atmosphere, reaction media and molecular ratios of reactants.  A catalyst for the polymerization of olefins in a liquid hydrocarbon consists of a mixture of titanium trichloride and an aluminium dialkyl monochloride in a mol ratio of at least 2:1, the concentration of impurities being such that decomposition of aluminium dialkyl monochloride is kept to a minimum. The dialkyl monochloride may be the diethyl chloride and both catalyst components may be added portionwise during the polymerization.
