Title: Apparatus and method for stretching sheet material
IPC: B29C55/16
Filed: 1969-09-03
Abstract: 1,247,618. Stretching sheet material. SIERRACIN CORP. 3 Sept., 1969 [17 Oct., 1968], No. 43614/69. Heading B5A. Flat plastics sheets of, for example, acrylic resin, are stretched by clamps 50, 54 which engage the periphery of the sheet and which are spaced apart prior to and during the stretching by a distance which provides in the sheet during stretching a "stress factor" not exceeding 0À35 over at least 80% of the area of the sheet. The stress factor is defined as the numerical value of the expression (#48-#52)/# where #48 is the magnitude of the stress in the direction of the lines 48 of clamp 50 at any point in the sheet, #52 is the magnitude of the stress in the direction of the lines 52 of the clamp 54 at that point and # is the magnitude of the stress at a point in the middle of the sheet at which #52=#48. Furthermore, it is advisable that the width of the pads of the clamps is not more than 55% of the distance between the centres of the clamps. Under both of the above conditions a consideraly en-larged central area of the sheet is uniformly thinned and therefore usable and the stretching of the sheet between the clamps is the same as that at the centre, tearing of the sheet thus being avoided.

Title: Boron nitride and production thereof
Inventor: O'CONNOR TIMOTHY EDMUND
IPC: C08K3/38
Filed: 1961-12-15
Abstract: Turbostratic boron nitride is produced by heating a mixture of a boric acid and a nitrogenous organic compound, with removal of evolved gases, until a solid intermediate is formed, and heating this intermediate in contact with ammonia.  Specified nitrogenous compounds are urea, thiourea, biuret, triuret, cyanuric acid, ammelide, melamine, guanidine, aminoguanidine, cyanamide, dicyandiamide, semicarbazide, thiosemicarbazide, salts of the foregoing with volatile acids, or mixtures of the foregoing, volatile acids being defined as acids with boiling point less than 400 DEG  C. or acids which on heating to below 400 DEG  C. decompose leaving substantially no ionic residue.  Boric acids which may be used are orthoboric acid, metaboric acid, pyroboric acid, and condensed boric acids.  Gases evolved during the first heating step may be removed by heating under reduced pressure or by a stream of inert gas, for example nitrogen.  The turbostratic product is conchoidally fractured and translucent, has a preferred boron:nitrogen atomic ratio of 0.9:1 and surface area greater than 40 m2/g., and retains its turbostraticity on thermal annealing at 1700 DEG  C. in an inert atmosphere.  Metals and metal borides and nitrides may be prepared by heating a mixture of turbostratic boron nitride and a metal oxide of aluminium, titanium, zirconium, vanadium, tungsten, niobium, chromium, nickel, molybdenum, tantalum and lanthanum to above 1000 DEG  C. Specific examples relate to the preparation of turbostratic boron nitride by reaction of orthoboric acid with urea, biuret, thiourea, guanidine carbonate, aminoguanidine bicarbonate, thiosemicarbazide, melamine, cyanuric acid, ammelide, guanidine acetate, and a mixture of urea, guanidine carbonate and thiourea, and to the reaction of turbostratic boron nitride with tungsten and nickel oxides to give the metals, with aluminium oxide to give the nitride, with zirconium oxide to give a nitride-boride mixture, and with vanadium, niobium, molybdenum and tantalum to give borides.ALSO:Turbostatic boron nitride (see Division C1) is used as a filler in elastomers such as natural rubber, GRS, polybutadiene and polyisoprene, in amounts from 1% to 50% by weight of the elastomer, and in plastic compositions of polyisocyanate, polystyrene, polyethylene, polyvinyl chloride, polymethyl methacrylate, polyacrylate, polyacrylonitrile, and polyesters, for example "Dacron" (Registered Trade Mark), in amounts from 0.5 to 50% by weight.  The plastics may be in the form of fibres, films, foams and sponge products.  The boron nitride cross-links such elastomers and polymers.ALSO:Tungsten oxide, WO3, and nickel oxide, Ni2O3, are converted to tungsten and nickel respectively by heating with turbostatic boron nitride to above 1000  DEG C.  Turbostatic boron nitride is also used to form a surface layer rich in boride and/or nitride on a metal or metal alloy by direct contact heating (see Division C1).

Title: Process and apparatus for the catalytic cracking of gaseous or liquid hydrocarbons for the production of high calorific value gases more particularly town gas
IPC: F02B3/06
Filed: 1963-11-18
Abstract: <PICT:0986090/C4-C5/1> Town gas containing a reduced carbon monoxide content is produced by a process in which the hydrocarbon feedstock (liquid gas, refinery residue gas, gasoline, Diesel oils) is initially converted with steam in a pre-cracking zone to form a gas mixture consisting of predominantly low molecular weight hydrocarbons, hydrogen, and carbon monoxide and this mixture is divided into two component streams (a) and (b) of which (a) is cracked, optionally with added air, in a main cracking zone, to form water gas whose CO content is reduced by partial conversion with steam to carbon dioxide and hydrogen, and (b) is added, substantially unchanged, to the converted water gas before this leaves the main cracking tube.  The steam for conversion is preferably mixed with the feedstock in advance of the pre-cracking zone, together with the steam required in the latter; the process may be performed at normal or at elevated pressure. In the accompanying Figure a cracking furnace is composed of pre-cracking zone 7, main cracking zone 13, conversion zone 14 and mixing chamber 9, while apertures 15 at the bottom of zone 7 provide access to internal bore 8 of cracking tube 3 which by-passes zones 13 and 14.  Hydrocarbon feedstock and steam, preferably preheated, is fed at 5 and is heated by passage through 7. One component of the effluent from 7 escapes through 15, passes down through 8 and reaches chamber 9 without further change of composition.  The remaining gas effluent from 7 may be mixed with air from 11 to 9 cracked in zone 13, which is fitted with catalyst, e.g. nickel. The gas product of cracking passes to zone 14 which effects at least partial conversion of CO to CO2 by means of e.g. an iron catalyst.  Effluent from 14 is then mixed with the unchanged product from 7 in mixing chamber 9 to produce a gas having the calorific value and density characteristic of town gas.
