Title: Improvements in or relating to the production of butadiene polymers
IPC: C08F36/06
Filed: 1959-03-13
Abstract: Butadiene is polymerized in the presence of a catalyst comprising titanium tetraiodide and a compound of the formula RnM where R is an alkyl group of 1-12 carbon atoms and M is mercury or zinc (of valency n).  The polymer formed generally has more than 85% cis 1, 4addition. Suitable metal alkyls are dimethyl, diethyl, di-isopropyl, di-n-butyl, di-isobutyl, din-hexyl, or di-n-undecyl mercury; dimethyl, diethyl, di-isopropyl, di-n-butyl, di-n-hexyl, di-n-octyl, di-n-decyl or di-n-dodecyl zinc.  The mol ratio of this compound to titanium tetraiodide may be from 1,0 to 50 and the total amount of catalyst may be 0,05-10% by weight of butadiene.  The catalyst may be pretreated by contacting together and ageing at -100 to 30 DEG C. for 1 minute to 24 hours.  The polymerization temperature may be 0-150 DEG C. in the liquid phase or -100 to 0 DEG C. in the solid phase.  A diluent is preferably added such as benzene, toluene, xylene, ethylbenzene, propane, n-butane, n-pentane, isopentane, n-hexane, isohexane, isooctane, n-decane, cyclohexane, or methylcyclohexane. When working in the solid phase the diluent may be cooled to just above the freezing point, adding other materials and placing in a refrigerating zone or by mixing the catalyst and diluent, freezing, grinding and adding the fragments to the butadiene.  The catalyst is destroyed and polymer precipitated by an alcohol, preferably after addition of phenyl betanaphthylamine.  Specification 848,065 is referred to.ALSO:A catalyst for polymerizing butadiene comprises titanium tetraiodide and a compound RnM where R is a C1-C12 alkyl and M is mercury or zinc of valency n.

Title: Improved process for purifying rock salt
IPC: C01D3/14
Filed: 1919-09-16
Abstract: Rock-salt is purified for table use by first comminuting it into grains of about 1 mm. in size and sifting, and then grading the grains in saturated salt solution according to their specific gravity.  By the process of comminution, the more brittle impurities, such as anhydrite, are broken down into fine powder, which is sifted away; whilst in the grading treatment, the heavier particles, such as the sulphate of calcium and magnesium, collect in the lower part of the grading-device and the pure salt in the upper part.  The grading-devices are of the kind in which an inclined sieve is agitated in salt solution, or in which the comminuted salt is moved against the flow of strong brine.

Title: Improvements in or relating to methods of modulating carrier waves
IPC: H01J31/44
Filed: 1937-03-30
Abstract: 493,048. Electron multipliers ; modulating circuits. BAIRD TELEVISION, Ltd., and NUTTALL, T. C. March 30, 1937, No. 8981. [Classes 39 (i) and 40 (v)] A carrier wave is modulated by applying potentials varying at the carrier frequency to one or more electrodes of an electron multiplier, the primary electron current of which is derived from a light sensitive surface (including a mosaic surface) adapted to receive light from the scene, an image of which is to be transmitted in a television system. The electron camera shown comprises a photoelectric cathode 2, target 3 with a scanning aperture 4, and electrodes 5 forming an electron multiplier. The electrodes 5 are maintained at potentials which increase towards the collecting electrode 6, and to one electrode is applied a carrier frequency alternating potential by means of transformer 7. The mean potential of this electrode is maintained substantially at that of the preceding one by connection to it through the carrier frequency choke 8 and the asymmetrical potential results in a non-linear relation between the potential variations of this electrode and the electron current so that modulation product currents are generated. Potentials may be applied to electrodes of the multiplier to reduce the output to zero during the flyback periods of the scanning device. Specification 492,662 is referred to.

An oxidising agent such as potassium bromate, iodate or persulphate, or calcium peroxide, may be included as a gluten maturing agent. The conditioner is made by melting the emulsifier and adding the particles of -SU compound thereto. The mixture is then converted to a powder by atomising and cooling, or by cooling and milling. A diluent and the maturing agent are added if required either before or after the mix has been converted to powder to give a conditioner comprising, e.g. 42-87.35% diluent, 50-12.5% emulsifier and 8-0.25% sulphur containing material. Ascorbic acid may be added to the emulsifier at the same time as the sulphur containing material.

The dough can be made by mixing cereal flour, water and other ingredients with a prefermented yeast brew, including the conditioner. The dough may be baked or sold as a frozen product.
