Title: Production of stainless steel
IPC: C21C7/00
Filed: 1944-12-28
Abstract: A method of making stainless steel directly from chrome ore comprises continuously smelting in a ferro-alloy furnace a charge including chrome ore, a carbonaceous reducing material and iron ore which may be wholly or partly replaced by steel scrap, mill scale or hammer scale, all in such selective proportions as to produce an impure stainless steel of chromium and iron contents approximately the values desired in the finished steel, and subsequently decarburizing the impure steel in a steel-making furnace, thereby incidentally oxidizing some of the chromium of the steel to form a slag component, and thereafter recovering into the steel bath the chromium so oxidized by adding to the slag a non-carbonaceous reducing agent, e.g. ferro-silicon.  The ferro-alloy furnace may have a magnetic lining and the steel-making furnace may have a chromite lining.  The ore charged into the ferro-alloy furnace may be low-grade chrome ore giving a chromium content in the impure stainless steel of 10 to 35 per cent, the carbon content having a maximum of 2 per cent.  The molten metal may be withdrawn from the ferro-alloy furnace in an intermittent manner, a portion being retained on each occasion. The metal may be decarburized in the steel-making furnace by oxidizing the carbon with iron oxide, the metal oxides of the slag being subsequently reduced; and to the charge chromium-containing slag resulting from the first smelting step may be added.  Iron ore may be charged into the steel-making furnace to serve as a slag constituent and to decarburize the metal.  The steel-making furnace may be an electric arc furnace in which the bath is decarburized by maintaining a thin slag and uniform operation of the furnace electrodes. Additional chrome ore may be charged into said furnace whereby any variations of chromium content in the metal from the desired value may be adjusted.  To prevent silicon contamination of the metal burnt lime, which may be pre-dried, may be added to the steel-making furnace.  Specifications 282,387, [Class 82(i)], 400,747, and 428,950 are referred to.

Title: Improvements in or relating to automatic variable speed transmissions
IPC: F16H47/06
Filed: 1956-08-30
Abstract: 814,999. Change-speed gear. DUFFIELD, W. A. Aug. 30, 19.56 [Sept. 2, 1955], No. 26570/56. Class 80 (2). An automatic change-speed gear for a vehicle comprises an hydrodynamic torque-converter 10 of the overrun reactor type, which drives through countershaft gearing 57 &c. at one ratio and is automatically by-passed by a friction clutch 63 at a numerically lower mechanical ratio in response only to countershaft speed, together with a manual range selector 71, providing two or three ranges of operating ratios. In low range the synchromeshed clutch 71 is manually slid rearwards -to clutch an output shaft 69 to a freely mounted toothed wheel 68. First ratio drive passes from the engine crankshaft 13 through the torque converter 10, a release clutch 27, wheels 51, 57, one-way clutch 58, countershaft cluster 59, wheels 66, 68 and clutch 71 to the output shaft 69. At a predetermined adjustable speed of the countershaft 59, a centrifugal switch (Figs. 2 and 3, not shown), driven by a countershaft wheel 65, energizes a solenoid valve directing pressure from the engine lubrication system through a line 122 to act on a piston 128 engaging the disc clutch 63 in opposition to torque-converter pressure to provide a direct mechanical drive to an inner shaft 20 and thence, through meshing wheels 62, 61, to the countershaft, overrunning the one-way clutch 58, to drive through the wheels 66, 68, as before, but-now at higher speed. To shift to high range the synchromeshed clutch 71 is manually moved forwards to clutch the output shaft 69 direct to the inner shaft 20. The converter-driven low ratio is now through the wheel pairs 51, 57 and 61, 62, and the automatic upshift is to mechanical direct drive. For reverse, the synchromeshed clutch 71 is neutralized and a splined output wheel 81 is slid axially to mesh a countershaft-driven idler 82. Automatic upshift as above can still occur. An additional manual forward range may be provided by meshing the sliding wheel 81 with an additional countershaft wheel (Fig. 7, not shown). The release clutch 27 is released in neutral by mechanical, hydraulic or vacuum means not described. Torque converter pressure is regulated by a relief valve 137 spilling to a lubrication line 138 for a bearing 21. A one-way clutch 56 is arranged directly between the wheel 51 and the shaft 20 to prevent free-wheeling of the vehicle when the by-pass clutch 63 is disengaged.

Title: A new or improved process for the extraction of oil from vegetable materials
IPC: C11B1/04
Filed: 1930-09-08
Abstract: In the extraction of fats from vegetable materials with an organic solvent, the vegetable material is pretreated with an aqueous solution of a volatile alkali such as ammonia or water soluble amines, e.g. methylamine or hydrazine, whereby mucilaginous and bitter ingredients are removed therefrom.  Soya beans, corn germs, or flax or cotton seeds are treated below 180 DEG  F. with a small amount of aqueous ammonia, and after agitating and standing the aqueous liquor is removed from the beans by heating and the beans are flaked or powdered.  An organic solvent such as di- or trichlorethylene, carbon tetrachloride, benzene, petroleum naphtha or an alcohol-ether mixture, is then added to extract the fatty oil. The oil extract is decanted, filtered and part of the solvent removed by distillation.  The concentrated extract is treated with a filter aid such as kieselguhr or decolorizing carbon and after filtration the balance of the volatile solvent is distilled off.  Final traces of solvent are removed by passing a current of dry steam, warm air or carbon dioxide through the oil. The extracted residue is dried by heating, preferably in vacuo, in a current of a gas and the residue is suitable for cattle feed. The process may be applied to the recovery of oil from press cakes.
