IPC: B21B13/12
Filed: 1969-08-21
Abstract: 1,271,140. Rolling. HITACHI Ltd., and YAWATA IRON & STEEL CO. Ltd. 21 Aug., 1969 [8 Feb., 1969], No. 41719/69. Heading B3M. A method of operating a rolling mill comprises predicting roll settings for a number 1-j of initial passes based on ingot size and material, due allowance being made for mill constraints, measuring, during one of these passes k(1#k#j), the resistance to deformation of the material being rolled from the actual rolling load or rolling torque, calculating the optimum number of passes required to obtain a final size and calculating the rolling torque required to give the shortest total rolling time. An apparatus comprises vertical and horizontal rolls 3 and 4 with an entry table 1 and delivery table 2, the roll torques being measured by means 20, 21 the rolling loads by means 18, 19 and the roll separations by means 16 and 17 respectively for the vertical and horizontal loads. A schedule for initial roll passes 1-j, PS<SP>1</SP> i , is prepared by a unit 100 based on standard data for the ingot to be rolled and the various mill constraints and a second schedule for the j + 1th to the final pass, PS<SP>11</SP>j, is prepared by means 200 from actual data, obtained during the kth pass, for the ingot being rolled. Preferably there are three initial passes, data being collected by means 150 on the second pass and computed by means 200 during the third.

Filed: 1972-09-12
Abstract: 1389754 Enamelling SYBRON CORP 12 Sept 1972 [29 Nov 1971] 42373/72 Heading C1M A method of applying a glass coat to an article maintaining the article at a temperature of at least the fusion point of the glass, e.g. 1500- 1850 F., depositing particles of the glass upon the article at a rate no greater than the rate at which these particles fuse to the surface. The method may be used to apply both ground coats and cover coats to metallic substrates. However in the case of an article of steel it is preferable to apply the ground coat, e.g. an alkali borosilicate glass, as an aqueous slurry, which may be applied by spraying, dipping or slushing. The particles may be applied by conventional techniques, e.g. by using a screen or dredge with a mechanical vibrator attached or by electrostatic deposition. The glass powder may be applied pre-heated. Typically the particles are of such a size that at least 90% by weight are from 20 to 325 U.S. mesh, e.g. -140+250. Deposition rates up to 15 mil. per minute are satisfactory, deposition rates of 5-10 mil. per minute being preferred. Cover coats being at least 20 mil., e.g. 50-80 mil. thick and having a porosity less than 5% may be produced by the method. The glass composition may be any conventionally used in enamelling including crystallizible glasses which form partially crystallized coatings. In examples the glass compositions specified are, in per cent by weight, (a) 75À2% SiO 2 , 1À72% ZrO 2 , 4À28% B 2 O 3 , 3À0% Li 2 O, 16À0% Na 2 O, and (b) 58À7% SiO 2 , 8À0% TiO 2 , 3À4% ZrO 2 , 16À0% Na 2 O, 3À0% Li 2 O, 6À3% K 2 O and 4À6% CaO.

Title: Production of aluminum triaralkyl compounds and alkyl aromatics therefrom
IPC: C07C15/00
Filed: 1959-12-28
Abstract: Triaralkyl aluminium compounds containing an average of 2 to 40 carbon atoms per alkyl group are prepared by reacting triphenyl aluminum, tribenzyl aluminium or tri-(b -phenylethyl) aluminium or C1-3 alkyl substituted derivatives of these compounds with ethylene at elevated temperatures and pressures. The reaction may be conducted at temperatures of 85-150 DEG C., pressures of 350-7500 p.s.i.g. and reaction times of 0.25-25 hours obtaining an ethylene uptake of 1-60 moles per mol of organo aluminium compound.  It is preferred that the starting organo aluminium compound be prepared using a non-nickel catalyst; thus tri-(b -phenylethyl) aluminium may be made by reacting triisobutyl aluminium or diisobutyl aluminium hydride with styrene, or from oxide-free aluminium, styrene and hydrogen, and tribenzyl aluminium may be prepared by reacting benzylchloride with aluminium to give benzyl aluminium sesquichloride which may be reacted with an alkali metal, e.g. Na, to give tribenzyl aluminium.  The triaralkyl aluminiums may be hydrolysed by water, aqueous acids or alcohol water mixtures to give alkyl aromatic hydrocarbons, which in turn may be sulphonated by conventional means to yield detergent compounds.  In an example the hydrolysed product which is sulphonated contains a mixture of hydrocarbons ranging from C2H5C6H5 to C36H75C6H5.
