Abstract: 1,053,675. Mould and core materials. UNILEVER Ltd. Nov. 18, 1963 [Nov. 16, 1962], No. 43526/62. Heading B3F. [Also in Division B5] A shell mould is made by alternately applying, to an expendable wax or polystyrene pattern, a coating of a gel-forming acidhydrolysed alkyl silicate solution and a coating of a quaternary ammonium silicate solution, at least one of which has refractory material suspended therein. In an example, a first slurry is made from 12 lb. of zircon and 3 lb. of acid-hydrolysed isopropyl silicate solution. A second slurry is made from 200 gm. of zircon and 50 gm. of tetraethanolammonium silicate solution. A wax pattern is dipped into the first slurry and the coating dusted with sillimanite, and then into the second slurry and again dusted. The process is repeated four times, and the shell is de-waxed, dried and then fired. The pattern may be given a primary coating of a suspension of a refractory material in an electrolyte-free silica aquasol.

In an automatically actuated hydraulicallyoperated motor vehicle change-speed gearshift control having a separate shift valve 91, 98 controlling shifts between each adjacent pair of ratios (i.e. 1 : 2 to 2 : 1 or 2 : 3 to 3 : 2 &c.), each shift valve 91, 98 is responsive to output speed governor pressure, supplied at duct 241 to its shift piston 91, opposed by a spring load 105 which is augmented above a predetermined accelerator pedal position by T.V. (throttle variable) pressure supplied via ducts 220, 220d and 221 and controlled by a valve 40 the piston 42 of which is operated by the accelerator pedal, whereby gear shifts are effected at a constant output speed solely by output governor pressure up to the predetermined acceleration position and are delayed or downshifted (i.e. kick-down) as acceleration pedal movement beyond the predetermined position moves the T.V. piston 42 to pressurize first ducts 220, 220d and then 221 to resist upshift by increasing the opposition to the governor pressure and thus raising the speed at which upshift then occurs. The T.V. pressure supplied via ducts 220, 221 acts on differential loads 91a, 91b of the shift piston such that a hysteresis between upward and downward shift points is obtained (Fig. 4, not shown). Each shift valve is movable between two positions to pressurize, from a duct 213, one or other ducts 216 or 215 respectively connected to the gear shift element and the next following shift valve, the remaining duct 215 or 216 being vented at 99 or 104. The T.V. pressure at duct 206 is balanced against a spring load 43 by a spool valve 41a, 41b having a back feed 49 and vent 44 whereby the T.V. pressure is regulated according to the spring load.

Abstract: 1295534 Cleaning hydrocarbon oxidation plants HALCON INTERNATIONAL Inc 19 March 1970 [20 March 1969] 13360/70 Heading C7E [Also in Division C2] The interior of a plant which has been used for the oxidation of saturated hydrocarbons in the presence of boron compounds is cleaned by treatment with an alcohol at elevated temperature in the absence of oxygen. The cleaning is preferably at elevated pressure, e.g. 1-6 atm. gauge and 100 to 200‹C, an inert gas such as N 2  being passed through the plant; the alcohol may be ethanol, a propanol, butanol, pentanol, hexanol, octanol, methyl cyclohexanol, or cyclohexanediol, or cyclohexanol, cyclooctanol, cyclododecanol or ethylene glycol, but is preferably the alcohol produced in the plant by oxidation of a hydrocarbon, possibly in solution in said hydrocarbon. In the plant shown, the oxidation of hydrocarbons, e. g. cyclohexane, proceeds as follows: cyclohexane (A) pre-heated in exchangers 2, 3, is fed to oxidation reactor 8, whilst a side stream plus additional cyclohexane (B) is fed via pre-heater 6 and vaporizer 7 to 8. Cyclohexane/orthoboric acid slurry (C) is dehydrated at 1 and thus cyclohexane/metaboric acid passes to 8 together with oxidation air (D) from compressor 15 and cyclohexane is oxidized in 8 at 160‹-180‹C., boric acid cyclohexyl ester being produced. Liquid from 8 passes via 9 to flash column 10 where unconverted cyclohexane is distilled off, (K), the bottoms going to hydrolyser 11 where the boric acid ester is hydrolysed by boric acid mother liquor from centrifuge 14, plus water. 12 is a phase separator where aqueous phase (to 13) and organic product (M) are separated. 1, 8, 9 and 10 are prone to scaling by boron compounds, and cleaning is as follows: suspended and dissolved B compounds are flushed out with cyclohexane after cutting off the supply of air (D) and boric acid (C), pressure in the apparatus being supplied by N 2 . Boric acid scale and resinous deposits still remain in the apparatus, and are removed thus: product from 12 is recycled to A, B, and C, and distillate from column 10 is returned as reflux, whilst oxidation product (92% cyclohexanol, 8% cyclohexanone) is added to the said product from 12 to give therein a cyclohexanol concentration of 10-11% and this solution reacts with boric acid scale giving an ester and liberating water which collects in separator 5, the cessation of formation of water indicating complete scale removal.

The address track is read by head 34 and when an address signal (42) is omitted, due to the operation of blank frame sensor circuit 32, gate 37 opens to allow frame pulses (25) from head 26 to pass to counter 24.
