Title: Improvements in or relating to the manufacture of steel cutting tools
IPC: C21D8/00
Filed: 1963-02-22
Abstract: Blanks for flexible cutting tools are prepared from an unstable nickel chromium austenitic steel containing up to 0.5% by weight of carbon by heat treatment in the range 950-1250  DEG C., quenching, cold working to bring about a 75-96% reduction in cross-sectional area at a temperature such that the product contains at least 40% of martensite, and finally tempering within the range 350-550  DEG C. Preferred compositions are those containing in percentage by weight <TABS:0979512/C6-C7/1> The cold deformation may be achieved by rolling which is preferably carried out in the range 15-30  DEG C. but which may be carried out at temperatures down to -10  DEG C.  The rolling process may be so arranged, e.g. by the use of shaped rolls, that a greater amount of deformation is given to that part of the blank forming the cutting edge, whereby a higher martensite concentration occurs there.  Cutting edges may be formed, and a final grinding given, before or after the tempering treatment.

Title: Improvements relating to the treatment of dolomite and other natural carbonates of magnesium
IPC: C25C3/04
Filed: 1930-03-10
Abstract: Roasted dolomite or other natural magnesium carbonates are chlorinated in stages, calcium being removed as a soluble chloride in the first stage, and magnesium being removed as a chloride free from gangue and insoluble impurities in the second stage.  The roasted material may, for instance, be boiled with the requisite amount of ammonium chloride to remove the calcium as chloride, which is then treated in the cold with the ammonia evolved and with carbon dioxide from the roasting operation to obtain calcium carbonate and ammonium chloride for re-use.  The residue of magnesium oxide and impurities is treated with hydrochloric acid to obtain a solution of magnesium chloride from which crystalline magnesium chloride is obtained.  The crystals are dehydrated and electrolyzed to obtain magnesium, and chlorine which after conversion to hydrochloric acid may be used again.  Alternatively the roasted material may be treated with hydrochloric acid to obtain the calcium chloride, the residue of magnesia &c. be treated with ammonium chloride to form the magnesium chloride, the calcium chloride be converted as before to calcium carbonate with recovery of ammonium chloride, and the magnesium chloride be electrolyzed as before and the chlorine be converted to hydrochloric acid for re-use.  In a modification the calcium chloride is recovered as such, and the magnesium chloride obtained by the use of ammonium chloride converted to carbonate with recovery of ammonium chloride for re-use.

Title: Mechanism functioning by the action of an element which is operative when on one side or the other of a variable position
IPC: G05D9/12
Filed: 1926-03-22
Abstract: 260,541. Volet, R. A. L. Oct. 27, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Retractive quick-action switches; flexible-pull centrifugal or pneumatic actuation; electromagnetic switches.-The Specification describes mechanism particularly for use in an electric switch which is actuated by floats attached to a chain 12, and used to control an electric pump supplying liquid to a reservoir. When the liquid falls below a predetermined level, the chain 12 pulls a link 11 downwards, causing an arm 6 to turn about its pivot 7 thereby tensioning a spring 9 anchored to an arm 1 which is pivoted at 3 and which carries contacts 5. When the arm 6 passes below the pivot 3, the arm 1 snaps against a projection 23 and closes the contacts 5 on to fixed contacts 15. In this closed position the arm 6 is still above the pivot 7, therefore the spring 9 tends, to return the arm 6 to its original position. When the liquid rises above another predetermined position, higher than the first, the pull on the chain 12 is insufficient to maintain the arm 6 in the displaced position, the arm 6 therefore returns to its normal position, whereupon the arm 1 also returns to its " off " position. The chain 12 may be operated by fluid pressure, electromagnetic or centrifugal means.
