Title: Improvements in or relating to oxygen liberating compositions and methods of preparing same
IPC: A62B21/00
Filed: 1946-05-06
Abstract: A composition capable of liberating oxygen upon contact with exhaled air is made by dry mixing an alkali metal peroxide and a minor proportion of a dry solid inorganic acidic substance (i.e. a substance containing hydrogen replaceable by a metal) while maintaining the mixture at a temperature at which substantially no reaction occurs, and heating the mixture to initiate reaction between the ingredients to produce a hard bonded, porous mass which may then be granulated or pulverized.  According to a modification, the ingredients are mixed at a temperature not above 55 DEG  F., compressed and then heated.  The heating may be effected while the pressure is maintained.  To promote reaction with vitiated air, the compositions may contain, as catalysts, the sulphates, chlorides, oxides or carbonates of the heavy metals. Lithium oxides and hydroxide may be included in the compositions. Ingredients specified are: sodium peroxide, potassium tetroxide, ortho- and meta-boric acids, silicic acid, sodium bicarbonate, disodium and dipotassium hydrogen phosphates, sodium and potassium dihydrogen phosphates and alkali acid sulphates. Exhaled air may be regenerated by passing it into contact with the compositions.  Specification 624,085 and U.S.A. Specification 2,160,542 are referred to.

Abstract: 528,914. Sink-and-float method. NAAMLOOZE VENNOOTSCHAP DOMANIALE MIJN MAATSCHAPPIJ, and TROMP, K. F. May 8, 1939, No. 13662. [Class 82 (ii)] In a sink-and-float method of separating mixed materials the relatively small particles of the materials introduced are caused to fall into the liquid mass at a speed exceeding that at which the relatively large particles are caused to fall therein. Means are provided for relatively retarding the falling velocity of the large particles and/or for relatively accelerating that of the small particles. In the form shown, the large particles falling down shoot 6 are retarded by flexible strip 8 of rubber or leather and the small particles falling down shoot 7 are accelerated by conveyer band 10, so that the small heavy particles are not prevented from sinking. Baffle 5 compels the particles to submerge and horizontal currents of light suspension from aperture 3 and of heavy suspension from aperture 4 assist the separation. The direction of the conveyer band may be reversed, or the band may be replaced by a rotating drum. In place of strip 8 the shoot 6 may be divided into two shoots at right angles so as to reduce the velocity of the large particles. Specification 466,964 is referred to.
