Title: Production of high quality steel from nickeliferous lateritic ores
IPC: C21B13/00
Filed: 1961-05-01
Abstract: Nickel-steel is made from Ni-Cr containing iron ore, particularly laterite, by charging a reducing furnace with the ore and reducing agent and preliminarily reducing at 800-1200  DEG C. to produce partially reduced sponge iron containing 15-45% metallic iron, then charging the sponge iron with reducing agent and flux, e.g. coke/charcoal and lime, into an electric furnace and reducing to produce pig iron containing at least 3.6% C, 1.0-1.8% Ni, 2-6% Cr and inevitable elements Si, Mn, P and S, and refining the pig iron in an oxygen blown converter to obtain steel containing less than 1% Cr and as much Ni as contained in the pig iron. Preliminary reduction of the ore, preferably preheated at 700-1000  DEG C. to effect dehydration, may be effected in a rotary kiln using coke or anthracite or a gas reducing furnace, such as a shaft-type roast or fluid type furnace, using natural gas or waste gas from an electric furnace.

Abstract: 934,036. Cam mechanisms. GEORGE KENT Ltd. Aug. 17, 1959 [May 16, 1958], No. 15829/58. Class 80 (3). In steering or other mechanism comprising a helically grooved cam 1, Fig. 1, which is engaged successively by two or more followers 5, 6 on a rocker arm 4, the cam is of normal cylindrical form and each follower is axially movable in the rocker arm and is individually urged towards the cam by a spring 9, Fig. 3, acting between a threaded plug 12 in the arm 4 and a cup-shaped pad 11. The spring 9 may be replaced by Belleville washers or a rubber block. The pad 11 co-operates with the plug 12 to limit the axial movement of the follower away from the cam. This limitation may be varied by inserting shims between the pad 12 and the roller bearings 8 supporting the follower. It is stated that the resilient mounting ensures that road shocks are absorbed. In order to determine the axial position of the rocker shaft 3 it is urged away from the cam by Belleville washers 3<SP>1</SP> against an adjusting screw, Fig. 2 (not shown), mounted in the gear housing 2.

Patent GB-573702-A (GB)
Title: Preparation of alkali metal hydracrylates
IPC: C07C51/41
Filed: 1943-09-28
Abstract: Alkali metal hydracrylates are prepared by adding ethylene cyanohydrin to an aqueous solution of a strong base of an alkali metal which is maintained at a temperature of at least 70 DEG  C.  In an example, the strong base used is sodium hydroxide.  During the addition of ethylene cyanohydrin, the solution of the base may be agitated mechanically and removal of ammonia facilitated by the introduction of a small stream of steam.  On completion of the reaction, residual ammonia and water may be evaporated off and the product purified by, for example, recrystallization or solvent extraction.  The sodium hydracrylate can be converted to another alkali metal hydracrylate by first forming the free acid by treatment with, for example, sulphuric acid.  Other strong bases which can be used in the above process are potassium hydroxide and sodium and potassium carbonate.  The process may be carried out also at reduced or elevated pressures.  Specification 573,384 is referred to.
