Abstract: 1,234,163. Sheet forming. GOODYEAR TIRE & RUBBER CO. 4 March, 1969 [1 April, 1968], No. 11356/69. Heading B5A. Closed containers are made by drawing a first sheet into a first mould and a second sheet into a second mould, the sheets being peripherably sealed together prior to drawing either sheet or after one of the sheets has been drawn, and curing the container thus formed. In the particular embodiment, a container suitable for carrying a hydrocarbon such as petrol is made from sheet material comprising a rubbery polymeric base layer and a barrier layer of a hydrocarbon resistant material by first sucking a first sheet 1 into a first female mould 4 placing a second sheet 12 over the drawn first sheet so as to peripherably adhere to it, and finally sucking the second sheet into a second female mould placed over the first mould. The sheets may be initially softened by hot air and are finally cured in a hot air oven. During the shaping of the second sheet, air from the atmosphere enters between the two sheets through a tube 10 previously passed through the first sheet. In a second embodiment, the sheets are adhered together and then blown into the moulds, or in a third embodiment the first sheet is drawn as before and the second sheet applied to the second mould not by vacuum but by pressurized air introduced through tube 10. The sheets may be adhered together by heat sealing if the barrier layer is of suitable material, by a conventional adhesive, or by a strip of curable material interposed between the sheets.

Abstract: 1290519 Carbon black CITIES SERVICE CORP 22 Dec 1969 [2 Jan 1969] 62211/69 Heading C1A In a process for preparing carbon black by thermal decomposition of a normally liquid hydrocarbon in the presence of hot combustion gases the properties of the product are improved by dilating the reaction mixture of hydrocarbon and combustion gases with a cooler gas before the carbon black is completely formed but after its particle size and structural characteristics have been substantially established. The diluent gas, which must be inert to the carbon black, is passed into the reaction mixture at a temperature of at least 1400‹ F. and in an amount equal to at least half the volume of the reaction mixture. It may suitably be the gas produced by combustion of a hydrocarbon fuel, particularly part of the gaseous products of the carbon black process itself. These products may be recirculated externally but are preferably made, by the use of suitable apparatus and reaction conditions, to recirculate within the re-  action vessel in the manner illustrated. In Fig. 1, fuel and air are supplied to combustion chamber 3 via jets 5 and ports 8 and hydrocarbon feedstock is injected in atomized form through sprayer 9. The reaction mixture is projected into carbon black formation zone 1 in the form of a columnar mass, 10, by passing through choke 2, which should have a diameter not more than a quarter of that of the zone 1. The mixture enters zone 1 moving substantially in-line rather than spiralling, and preferably travelling at at least 400 feet/sec. In the reaction zone part of the combustion gases recirculate as indicated at 11, being cooled by water spray 11 if necessary. The apparatus preferably has its axis vertical. A novel carbon black produced by this process is also described and claimed: it has a mean particle diameter of 150 to 650 A, a dibutylphthalate absorption of 40 to 80 c.c./100 g., and an agglomerate area (determined as described in the Specification) of below 500 Á<SP>2</SP>/mm.<SP>2</SP> and/or a crystallite dimension, L c , of more than 15-5 A.
