Title: Process for blowing pig iron to steel
Inventor: CUSCOLECA OTWIN
IPC: C21C5/46
Filed: 1954-06-15
Abstract: 756,618. Steel manufacture. OESTERREICHISCH-ALPINE MONTANGES. June 15, 1954, No. 17584/54. Class 72. A process for converting pig iron into steel by blowing oxygen through a nozzle on to the surface of the metal with insufficient energy to ensure immediate penetration of the slag layer, comprises piercing the slag layer within the area of impact of the blast with a solid body. As shown, an iron rod 6 may be attached to the nozzle 4 by a material 7, e.g. hemp or fusible wire, which is destroyed by the heat above the bath, the rod being of sufficient length to penetrate the slag layer 3 when the nozzle is lowered to its operating position. On destruction of the material 7 the rod falls into the metal bath. The rod may be replaced by a tube surrounding the nozzle, Fig. 2 (not shown) or a piece of scrap iron or steel or an alloying metal may be dropped from a tube adjacent the nozzle into the impact area of the blast, Fig. 3 (not shown).
Patent GB-719863-A (GB)
Title: Improvements in or relating to the production of oxygenated organic compounds
IPC: C07C29/16
Filed: 1951-07-25
Abstract: Alcohols are made by hydrogenating a fraction obtained by distillation of a product from the carbonylation stage in the conversion of olefines to oxygen-containing organic compounds by the Oxo-synthesis, the fraction boiling above the boiling range of the main aldehydic product of the said synthesis, so that the fraction is converted at least in part to alcohols having the same number of carbon atoms per molecule as the main aldehydic product. Preferably gaseous effluent is removed from the synthesis product by phase separation before distillation and hydrogenation.  When the olefinic feedstock has at least 3 carbon atoms per molecule the liquid phase thus obtained is preferably distilled to yield unreacted olefine, aldehydic and high-boiling fractions.  Usual hydrogenation catalysts may be present, e.g. nickel, cobalt or copper, optionally on supports such as kieselguhr or silica gel. With Raney nickel temperatures of 150-200 DEG  C. and pressures of 500-5000 p.s.i. are mentioned. Hydrogenation is preferably effected with nickel-on-kieselguhr catalyst in a fixed bed at 180-200 DEG  C. and 50-200 atmospheres with liquid feed rates of 0.5-2.0 vols./vols./hours.  Products from olefines of 2-4 carbon atoms per molecule afford a preferred feedstock.  Residues from the distillation of the alcohols obtained by hydrogenation yield higher alcohols and glycols, any esters, e.g. formates, obtained being saponified.  Preferably cobalt carbonyl or hydrocarbonyl catalysts, prepared outside the reaction zone, are used in the synthesis, c.f. Specifications 702,191, 702,192, 702,195, 702,196, 702,203, 702,204, 702,217, 702,221, 702,222, 702,224 and 702,242. In examples in which the feedstock is derived from propylene and the Oxo-synthesis products after catalyst removal are distilled to yield C3 hydrocarbons, iso- and normal-butyraldehyde and a high-boiling residue, the latter is hydrogenated in (1) in the presence of Raney nickel at 160 DEG  C. and 100 atmospheres to yield butanols; (2) as in (1) but at 130 DEG  and 190 DEG  C.; whilst in (3) the residue after removal of the butanols in (1) yields mixed high and low boiling esters and alcohols including a substantial quantity of C8 alcohols of which the chief isomer is 2-ethylhexanol and in (4) the butanol product of (1) is saponified to yield on distillation iso- and normal-butanol fractions.

Title: Improvements connected with Ordnance.
Inventor: STONE ANDREW JACKSON
IPC: F41A1/08
Filed: 1916-12-20
Abstract: 126,336. Stone, A. J. Dec. 20, 1916. Ordnance design.-Relates to the gun described in Specification 125,652, in which gun the recoil is eliminated by the rearward discharge of a mass which is light in comparison with the mass of the effective projectile, and which frictionally engages the tapered rear end of the barrel. According to the present invention, the rear end of the barrel has two stages of tapering, one of which acts on the light mass before, and one after the effective projectile has left the gun. The light mass is therefore arrested instead of passing out of the gun as described in the above-mentioned Specification, and the rear end of the barrel may be opened to enable the arrested mass to be removed. In the form shown, the projectile 4, the propelling charge 3, and a 'light mass 2 in the form of a soft-metal cup, are loaded into the forward part of the barrel. The rear part 1 of the barrel is tapered or reduced below the diameter of the cup 2 to offer frictional resistance to the passage of the cup. The cup is arrested in a further closed tapered portion 6 wherein air is compressed, the resistance being varied by an adjustable vent 9<a>. When the projectile 4 has just left the barrel, the cup uncovers adjustable ports 5 to relieve the pressure. To compensate for the arrest of the cup, a forward movement is conveyed to the barrel by the action of the gun gases which pass through adjustable ports 8 and act upon a flange 7.
