Title: Stable, curable polyurethane compositions and method of making same
IPC: C08G18/86
Filed: 1956-08-02
Abstract: A polyurethane composition comprises a reaction product of a polyether, other than one consisting solely of isopropylene ether groups, or a polyester or a mixture of a polyether and a polyester and a polyisocyanate, the reaction product having mixed therewith as a curing agent 0.2 to 8 parts by weight for every 100 parts of the reaction product of an organic peroxide of the general formula R1-OOR, where R and R1 are organic groups of at least 3 carbon atoms and at least one of the groups R and R1 is an araliphatic group having a tertiary aliphatic carbon atom, an aliphatic carbon atom of the araliphatic group being attached to the peroxide oxygen group and being connected directly to but one oxygen atom.  The amount of polyisocyanate is preferably equal to or only slightly in excess (6% to 15%) of that necessary to react with all the polyether and/or polyester.  For rubbery products the molecular weight of the polyester or polyether is preferably above 1000.  Rigid products are obtained when the polyethers or polyesters have molecular weights below 500 or 600 or by using a cross-linking agent such as trimethylol propane.  Suitable polyethers are mixed poly-(ethylene-propylene) ether glycols, poly tri-, tetra- or penta-methylene ether glycols and polyneopentylene ether glycol.  The peroxide is incorporated suitably by milling, and carbon black, synthetic wax, silicon dioxide and calcium carbonate can also be incorporated.  Examples illustrate the use of di-cumyl peroxide in the curing of polyesters (polyethylenepropylene adipate) and polytetramethylene ether glycol.  Comparison figures are given of the physical properties of a polyester urethane rubber (in some cases incorporating carbon black) with di-t-butyl peroxide, di-2,2-bis-(t-butyl peroxy) butane, t-butyl hydroperoxide, cumene hydroperoxide, methane hydroperoxide, t-butyl isopropyl benzene hydroperoxide, t-butyl perbenzoate, benzoyl peroxide, lauroyl peroxide, methyl ethyl ketone peroxide, cyclohexanone peroxide, methyl amyl ketone peroxide and bis-azoisobutyronitrile as curing catalysts.

Title: A process for the manufacture of sugars from cellulose-containing materials
IPC: C13K1/02
Filed: 1925-09-24
Abstract: 240,475. R÷mer, R., (Assignee of Pink, L.). Sept. 25, 1924, [Convention date]. Pulp, preparation of. - In the production of edible sugars from wood waste and other cellulose-containing materials by hydrolysis, the raw material is prelimilarily treated in the presence of dilute sulphuric acid in an open vessel with steam until it is sufficiently softened. The Specification as open to inspection under Sect. 91 (3) (a) comprises also in the production of sugars such as glucose and pentose and like substances from wood or other cellulose-containing materials by hydrolysis, a preliminary treatment of the raw materials so that the lignin or like substances are loosened or decomposed and more of the cellulose is made available for conversion and an increased yield of sugar is obtained. In one example, sawdust is mixed with water and about one per cent of hydrogen peroxide is added and the mixture saturated in a closed vessel with chlorine. It is then allowed to stand for about a quarter of an hour and chlorine again passed in until no further increase in weight is obtained. The product is well washed with water and then hydrolyzed with acid to sugar. In another example, wood is uniformly heated to 150‹ C. for about half an hour and then boiled for one hour with ten times its weight of 5 per cent sulphuric acid in a closed vessel. The liquid is separated and worked up to obtain sugar. This subject-matter does not appear in the Specification as accepted.
Patent GB-761717-A (GB)
Title: Cracking heavy hydrocarbon oils
IPC: C10G9/32
Filed: 1954-08-17
Abstract: Heavy hydrocarbon oils are converted into lighter products such as gas oil by a process in which the heavy oil is contacted with a stream of catalytically-inert solid particles at a high temperature (above 1000 DEG F.) for a short time (e.g. 2 secs. or <PICT:0761717/III/1> less) so that the oil is vaporized but not appreciably cracked, the vapours are separated from the particles, and are passed into a fluidized bed of inert solid particles at a temperature lower tan that in the vaporization line and the time of contact of the vapours in the bed is adjusted so that they are cracked to the desired products.  The vaporizing step may be carried out in a transfer line; and the separation of the particles is then effected in the base of the reactor which contains the fluidized bed. The process may be applied to residual oil and then yields a gas oil which is free from metallic contaminants; and it permits a high feed rate to be maintained without clogging of the particles in the bed. Suitable inert solids are coke, sand, pumice, metal shot, and ceramics.  In the Figure reactor 11 contains a perforated grid 15 to support a fluidized bed 17 of hot particles of petroleum coke.  Below grid 15 is a stripping zone 21 which contains a cyclone 45.  Steam is introduced into stripper 21 via line 67.  Coke particles at about 1050 DEG F. from burner 13, flow along transfer line 43 and are mixed therein with oil introduced through lines 51 and 53.  The mixture is discharged into cyclone 45; and the separated vapours rise through line 65 into fluidized bed 17, while the solids flow into stripping zone 21 through line 63.  Unvaporized oil may be fed direct to bed 17 via line 55, manifold 57 and nozzles 59.  The cracked products are withdrawn from the reactor via cyclone 69.  The solids in the bed overflow into line 61 which leads to stripper 21.  Spent coke particles are conveyed from the stripper to burner 13 via line 19, air being introduced through lines 23 and 25.  While in burner 13 the particles are fluidized and partially burned in the air.  The reheatd solids overflow partition 33, and flow into lines 43 and 37.  Line 37 leads to bed 17, provision being made to introduce fluidizing gas through lines 39 and 41.  The temperature of bed 17 may be raised by increasing the flow of solids through line 37 relative to that through line 43.  The temperature of the bed may be lowered by increasing the flow of oil through nozzles 59.  A heat exchanger may be inserted in line 37 so that cooler solids may be fed into the bed than into the transfer line 43.

Title: Process for the direct production of iron and steel
IPC: C21B13/10
Filed: 1924-10-13
Abstract: 245,223. TourniÚ, R. H. M. L. Oct. 13, 1924. Drawings to Specification. Extracting.-In a process for the production. of iron and steel from washed or unwashed ores, the ore together with the necessary fluxes and, if desired, carbonaceous material, is introduced into a tilting furnace and is melted in an oxidizing atmosphere produced by the combustion of coke-oven gas, water-gas, heavy oil vapours &c. for the purpose of burning off the harmful constituents of the ore. The slag floating on the molten bath is removed periodically, by tilting the furnace, until a bath of molten iron oxide which contains reduced iron is produced. The heating is then continued in a reducing atmosphere, the unburnt reducing gas acting on the surface of the molten oxide bath to reduce the same to metal which falls to the bottom of the bath, until the reduction is completed. In a modification, the molten oxide bath, after the removal of the slag is transferred into a converter where the reduction is completed by forcing reducing gas through the bath, the converter being heated by surface combustion effected by burners similar to those employed in Martin furnaces. By adjusting the duration of the reduction process, the metal may be carburized.
