Title: Improved polymerization catalyst and polymerization process
IPC: G05D23/275
Filed: 1960-09-05
Abstract: Ethylenically unsaturated compounds (including aromatic 1-olefins and dienes, but particularly aliphatic 1-olefins such as ethylene or propylene are polymerized in contact with a catalyst comprising a transition metal halide and the reaction product, substituted in its benzene ring with an alkali metal, obtained from the alkylation of benzene with low molecular weight olefin polymer, the reaction product having an average molecular weight between 150 and 400.  The preferred reaction product is that of dodecene (propylene tetramer) with benzene, which is fractionated to give "dodecylbenzene intermediate" (B.R. 350 DEG -450 DEG F., MW 160), "dodecylbenzene" (B.R. 530 DEG -600 DEG F., MW 237), "postdodecylbenzene overhead" (B.R. 600 DEG -685 DEG F., MW 300) and "stripped post-dodecylbenzene" (B.R. 630 DEG -770 DEG F., MW 385) the boiling ranges and molecular weight being approximate figures.  In Example 1, chlorination in absence of light and in presence of iron filings of "dodecylbenzene intermediate" gave, after distillation, a fraction of B.R. 143 DEG -170 DEG C., probably containing chloro-tert-butylbenzene, chloro-tert-amylbenzene and chloro-tert-hexylbenzene; this fraction was reacted with a dispersion of sodium in "Ponca City Heavy Alkylate", the reaction being initiated with n-amyl alcohol.  The organosodium compound is used in conjunction with TiCl4 to polymerize ethylene, using n-hexane diluent.ALSO:A polymerisation catalyst component is the reaction product, substituted in its benzene ring with an alkali metal, obtained from the alkylation of benzene with low molecular weight olefin polymer, the reaction product having an average molecular weight between 150 and 400.

Title: Improvements in or relating to methods of coating surfaces with boron
IPC: C23C16/28
Filed: 1946-10-14
Abstract: A thin coating of boron is applied to an article (e.g. of steel or glass) by passing gaseous boron alkyl compound over it while the article is maintained at about 550 DEG  C. within a chamber under reduced pressure.  Boron trimethyl may be admitted to the chamber while the pressure is maintained at 0.1 mm. of mercury, but small articles are coated more economically by admitting the compound intermittently and allowing the pressure to rise to 2 cms. of mercury.  If the triethyl or tripropyl compound is used, the coating is formed at a lower temperature.ALSO:Boron trimethyl is prepared by reacting magnesium with methyl iodide in an atmosphere of nitrogen, boron trifluoride being added in the form of its ether compound.  The trimethyl is separated by condensation in a trap cooled with liquid nitrogen and purified by fractional distillation.

Filed: 1964-08-04
Abstract: 1,071,823. Controlling the mixing ratio of liquids electrically. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V Aug. 4, 1964 [July 23, 1963], No. 30677/64. Heading G1N. The mixing ratio of two liquids being mixed is maintained constant by periodically or continuously measuring and comparing the liquid levels in each of two supply tanks as the liquids are respectively drawn therefrom. In Fig. 1 liquid level meters 9, 10 are electrically or mechanically coupled to the moving contact arms 14, 15 of variable resistors R 1 , R 2  in a bridge network so as to move the arms in accordance with the liquid level or reduction in level from a predetermined value. The mixing ratio is preset by adjustment of the values of R 3  to R 4  by a contact arm 13. Any deviation from a desired ratio unbalances the bridge and the unbalance voltage operates a controller 12, which adjusts a valve 8 to increase or decrease the rate of withdrawing liquid from tank 1, through pipe line 5 until the bridge is rebalanced. The liquids mix in pipe 7. Instead of continuous movement of the contacts 14, 15 they may be adjusted at intervals (e.g. every sec.). If more than two liquids are to be mixed there would be more than one bridge. Instead of using a bridge as a control device a double potentiometer circuit Fig.2 (not shown) may be used, which has the advantage that zero setting of the control device is independent of the initial level in the tanks.
