Title: Improvements in heat resistant alloys
IPC: C22C19/00
Filed: 1935-05-09
Abstract: Articles which in use are subjected to repeated high temperature heating and cooling are made from an alloy prepared by adding to a molten nickel-containing mass, prior to casting, one or more of the rare earth metals (including scandium, yttrium, hafnium, and thorium) in such a quantity that if there is any residue in the finished alloy, it does not exceed 0,5 per cent. For instance, electric resistance elements may be made from an 80-20 nickel-chromium alloy treated in this manner. Before the rare earth addition, the mass may be subjected to treatments for deoxidizing, desulphurizing, improving the forgeability, etc.; for instance, it may be treated with alkaline earth metals such as calcium, calcium silicide, a Group V element such as phosphorus, arsenic or antimony, selenium, sulphur, tellurium, manganese, magnesium, silicon, or boron. Carbon, copper, iron, phosphorus, and sulphur may be present as impurities and aluminium, cobalt, molybdenum, or tungsten may be used to modify the mechanical properties. The rare earth addition may consist wholly or mainly of cerium or lanthanum, or commercial cerium may be employed. The finished alloy may contain up to 0,25 per cent of carbon. According to the second Provisional Specification, zirconium and titanium may also be present. Specifications 311,799, [Class 82 (i)], and 396,514 are referred to.

Patent GB-463359-A (GB)
Title: Improvements in or relating to manufacture of zinc sulphide
IPC: C01G9/08
Filed: 1936-05-18
Abstract: Zinc sulphide is obtained by passing a mixture of hydrogen sulphide and carbon dioxide free from cyanogen compounds, sulphur compounds other than hydrogen sulphide, and organic compounds through an aqueous solution of an amminozinc salt such as the compound Zn(NH3)4(NO3)2, or Zn(NH3)4SO4, or Zn (NH3)4Cl2. To prevent formation of basic zinc carbonate, the solution should contain free ammonia. During the reaction a temperature of 50--80 DEG  C should be maintained.  After removal of the precipitated zinc sulphide the residual solution may be stripped of its content of free ammonia and be evaporated for the recovery of the ammonium salt formed.  The mixture of hydrogen sulphide and carbon dioxide for use in the process may be obtained by washing illuminating gas with an ammonia solution and heating the solution of ammonium sulphide and carbonate so obtained.  The gas mixture is washed with water to remove free ammonia, with a ferrous sulphate solution to remove cyanogen compounds, with straw oil to remove organic sulphur and other compounds, and finally contacted with charcoal to remove traces of organic compound vapours.

Abstract: 110,011. Pneumatic Loom Syndicate, and Pickstone, M. T. Oct. 4, 1916. Stop-motions, shuttle. -For stopping the loom when the shuttle fails to enter a shuttle box, each temple is carried by one end of a pivoted lever normally held in operative position against the action of a spring by a spring- controlled catch, so arranged that, when an unboxed shuttle is forced by the reed against the temple or the fell of the cloth, the resistance of the catch is overcome, and the lever is moved by its spring to effect the stoppage of the loom; means are provided for simultaneously relieving the warp tension. As shown applied to a vertical loom, each temple D, Fig. 1, is carried by a lever F on a shaft E and held against the action of a spring S by a spring catch G, which is disengaged by pressure of the shuttle on the fell or the temple so that the lever F is rocked and a finger T on its shaft E acts on a finger U to turn a rod V and stop the loom. At the same time, a rod H raises a catch-lever I and frees a warp-deflecting rod J carried by arms L on a shaft K, which is thereupon rocked by a spring S<1> and a lever M to relieve the warp tension. In a modification, the warp-deflecting rod 0, Fig. 2, is held in its normal position by a rod R, a lever M<1>, and a lever N connected to the rod H.
