Title: Process for the production of alkali metal and alkaline earth metal borohydrides
IPC: C01B6/00
Filed: 1960-11-09
Abstract: An alkali metal or alkaline earth metal borohydride is produced by reacting the appropriate metal hydride, or the appropriate metal and hydrogen, at a temperature between 50 DEG  and 500 DEG C. with a fluoroboric acid ester of the general formula FnB(OR)3-n, in which R is an aliphatic or aromatic hydrocarbon radical and n is 1 or 2. Preferred esters are those of difluoroboric acid, particularly the n-butyl ester, and other R radicals specified are methyl, ethyl, propyl, amyl, hexyl, octyl, decyl, dodecyl, phenyl and tolyl.  The preferred reaction temperature is from 120 DEG  to 200 DEG C.  An organic nitrogen base, e.g. triethylamine, dimethyl cyclohexylamine, and pyridine, or an ether, e.g. tetrahydrofuran and diisopropyl ether, may be present as a catalyst.  An inert dispersing agent may also be present, those specified being aliphatic hydrocarbons, e.g. paraffins boiling above 150 DEG C., and aromatic hydrocarbons, e.g. xylene, or mixtures thereof, and dimethyl ethers of mono-, di-, tri-, or tetraethylene glycol, these latter compounds also having a catalytic effect and therefore serving a dual purpose.  The reaction may be carried out in at atmosphere of hydrogen at superatmospheric pressure.  The process may be operated continuously, and the by-products, i.e. metal fluorides and boric acid esters, may be reconverted to fluoroboric acid esters by treatment of the fluoride with borax and oleum to give BF3, which is then reacted with the boric acid ester to give a fluoroboric acid ester.

Title: Method and apparatus for the manufacture of flexible sheets of heat cured foamed material
Filed: 1959-11-17
Abstract: Foam rubber sheets are made using the apparatus of the parent Specification modified in that the projections on the former are of electrically conductive material instead of electrically insulating material.  The electrostatic field set up by the high frequency source extends between the free ends of the projections and the electrode, thus raising the temperature of the portion of the foamed material overlying the projections.  This overlying portion will gel first and stabilise the foam on the drum, thus preventing substantial movement of the foam relative to the drum surface.  The rim on the former may also be electrically conductive, this distorting the electrostatic field, however, with the result that the depth of the foam within the field, and heated dielectrically thereby, becomes less the nearer the foam is to the rim and is zero at the rim.  Under some circumstances this lack of rapid gelling at the edges of the material is acceptable.

Filed: 1961-11-13
Abstract: <PICT:0960725/C1/1> Non-magnetic iron oxide ore containing impurities such as silica or alumina with melting points above those of iron oxides is enriched by subjecting it to a prior magnetizing roasting treatment to reduce the free iron oxides to ferromagnetic oxides under conditions given by the Chaudron diagram (in Fig. 1, not shown), e.g. at 600 DEG  C. for siderite or 800 DEG  C. for haematite with a reduction ratio of 0.1 to 0.3, sintering the ore below the melting points of the impurities e.g. at 1250-1450 DEG  C. in a reducing atmosphere of CO and CO2 with a reduction ratio of at least 0.85 to release iron oxides from the impurities and reduce them to ferromagnetic oxides, the sintering being carried out in the presence of water vapour preferably at least equivalent to 50% by weight of the Fe content in the ore to prevent over-reduction beyond Fe3O4 to FeO, and then enriching the Fe3O4 by low-power magnetic separation. After sintering but before separation, the Fe3O4 obtained may be abruptly cooled by passing into water and crushing at 250 DEG C. before complete cooling to release the impurities. The initial ore may be crushed to a grain size up to 10 mm. The above process may be carried out in the conventional apparatus shown in Fig. 2 comprising a horizontal rotary furnace 1 heated by a fuel burner, 3 which produces the reducing mixture of CO and CO2, water vapour being introduced through a nozzle 8, which furnace is connected to a ball mill 2.  The prior roasting treatment occurs in zone I whilst the sintering proper occurs in zone III, zone II being intermediate. The pulverized ore, e.g. of grain size up to 0.35 mm. is discharged by shoot 9 on to a magnetic sorter 10. Specification 960,726 is referred to.
