Title: Improvements in the treatment of textile materials
IPC: D06M15/333
Filed: 1934-08-30
Abstract: The fastness to washing and scouring of textile materials impregnated with insoluble metal compounds is improved by applying to the materials a solution in an organic solvent of a substance which forms a film on the materials which is substantially insoluble in aqueous scouring liquids.  Suitable materials for treatment are artificial silk materials which have been delustred or loaded by incorporating therein insoluble metal oxides or metal compounds.  The amount of film-forming material need not exceed 5 per cent of the weight of the textile materials, and this may be applied in solution of 5 per cent or less concentration.  Examples of suitable film-forming substances are polymerized unsaturated compounds such as polymerized vinyl acetate, polymerized vinyl chloracetate, polyvinyl ethers, polystyrene, polymerized unsaturated aliphatic aldehydes, polymerized esters of unsaturated aliphatic acids, urea-formaldehyde condensation products, phenol-aldehyde condensation products, phenolurea-aldehyde condensation products, alkyd resins and modified alkyd resins. Condensation products may be applied in partially or fully condensed form.  Other film-forming substances are cellulose esters, ethers, or ether-esters, and chlorinated rubber.  The solvent in which the film-forming substance is applied may have no solvent action or some solvent action on the textile materials.  The following examples are given: (1) Natural silk fabric is steeped in stannic chloride solution, rinsed, steeped in disodium phosphate, soaped, rinsed, and dried.  The loaded fabric is treated with a 1 per cent solution of cellulose acetate in acetone, passed through nip rollers and dried. (2) Cellulose acetate fabric is loaded by treatment first with a bath containing stannic chloride and ammonium thiocyanate, and then with a solution of sodium dihydrogen phosphate, after which it is treated with a 1,5 per cent solution of saponified polyvinyl acetate in 50 per cent aqueous alcohol.  According to the Provisional Specification, the following film-forming substances can be used, viscose, cuprammonium cellulose, ammonium cellulose xanthate, magnesium cellulose xanthate, or a cellulose xanthate of an organic amino base; furthermore, the film-forming substance may be contained in one of the reagents used for forming the insoluble substance on the materials.  Specifications 441,868, 441,869, and 443,726 are referred to.

Title: Improvements relating to the removal of sulphur dioxide from gases
IPC: B01D53/50
Filed: 1946-08-26
Abstract: Apparatus for the continuous determination of the excess of acidic or alkaline constituents of a gaseous mixture comprises an absorption system, means for supplying a continuous stream of liquid absorbent at a constant rate of flow, means for supplying a continuous constant flow of gaseous mixture, a feed vessel in which the gas mixture and absorbent meet and from which they pass directly to the <PICT:0633627/III/1> absorption system, and means for measuring the conductivity of the liquid having the absorption system.  In operation, wash liquor, i.e. the liquor obtained by contacting the gas mixture with a liquid is drawn by gravity through a feed tube a, flows as a thin stream down a stripping tube b, and leaves through a seal port e, whilst air is drawn through a vessel f to entrain water vapour, by a Springel pump a which operates at a constant rate.  The air passes through a pump separator i to a tube j and thence out through the stripping tube b in counter current to the wash liquid to the feed bulb k where it is absorbed in acid hydrogen peroxide. Air and absorbent pass together through the absorption tube m, thence to a conductivity cell o.  The absorbent is stored in a reservoir p and a stop cock s controls its admission to the absorption system, which is via a funnel t, a stop cock v and a surge bulb k1.  The stripping tube capillary r, the absorption tube m and the conductivity cell o are water jacketed, the water being delivered from a thermostat unit y.  In a modification (Fig. 3, not shown), the gas mixture can be analysed directly.

Filed: 1970-05-29
Abstract: 1312345 Cassette recorders OLYMPUS OPTICAL CO Ltd 29 May 1970 [30 May 1969 9 Aug 1969] 25954/70 Heading G5R A cassette recorder detects whether or not a cassette presented to it may be used for both playback and recording, and controls head movements accordingly. In the arrangement shown, the nose 32 of a lever 30, which is biased anticlockwise by a spring 31, enters a recess 25 of a cassette on the deck 3, thereby sensing that the cassette is for playback only. The movement of lever 30 causes a linked lever of a cassette on the deck 3, thereby sensing that the cassette is for playback only. The movement of lever 30 causes a linked lever 35 to rotate clockwise and hence a lug 37 to move into a cut-out portion 38 of a shift plate 27 bearing an erase head (not shown); a knob 17 cannot therefore be moved in either a direction a, or a direction b, as required by a pin/slot engagement 29/28, in order to bring the erase head to an operative position. If however the cassette recess 25 is blocked off to indicate that recording is also possible, the above movements do not occur and the knob 17 may be moved as desired. A lug 40 maintains the lever 30 in a withdrawn position until the deck 3 has been pushed downwards to a lower, operative, position. The locking pressure applied to the cassette by a pin 10 on a biased lever 41 may be released by rotating an eject lever 44. Further manually operated lever systems are described with reference to Figs. 4-28 (not shown).

Title: Improvements in or relating to the production of emulsifiable bitumens
Inventor: COURTOIS JEAN
IPC: C10C3/04
Filed: 1965-06-23
Abstract: An emulsifiable bitumen is prepared by blowing with air at elevated temperature, e.g. 150 DEG  to 350 DEG  C., an aromatic extract obtained from a Middle East or Saharan crude, the extract preferably being blended with up to 40% by weight of a vacuum residue derived from a Middle East or a Saharan crude.  Aromatic extracts are obtained by treating vacuum distillates, cracked oils therefrom, and deasphalted vacuum residues with selective solvents, commonly furfural, sulphur dioxide, and phenol.  Three blown bitumens are described and their specifications given.  One comprises an extract obtained from a Kuwait crude with furfural as solvent; the second comprises 70% b.w. of an extract obtained from a Zarzaitine crude with furfural and 30% b.w. of a vacuum residue of Kuwait crude; and the third comprises 70% b.w. of the first mentioned extract with 30% b.w. of the same vacuum residue.  The cut-off point of the residue is not given.  Three aqueous emulsions were prepared from each blown bitumen, one containing a soap (an unspecified resin and NaOH), one anionic containing NaOH (60% b.w. bitumen, 40% b.w. aqueous phase), and one acid containing an amine-type emulsifying agent.ALSO:Bitumens prepared by blowing with air at 150 DEG  to 350 DEG C an aromatic extract obtained from a Middle East or Saharan Crude, preferably blended with up to 40%b.w. of a vacuum residue obtained from such a crude, see Heading C5E, are emulsified according to the following three examples.  In one example, an aqueous solution of 25% b.w. of a resin containing soap-forming fatty acids, was neutralised by 3.7% caustic soda, and the solution added to the aqueous phase of the emulsion to give 2.5% b.w. of soap in the total emulsion.  In the second example, an anionic emulsion is made using an aqueous solution of caustic soda (pH 11 to 11.5).  In both the above examples, the bitumen forms 60% b.w. of the emulsion.  In the third example, an acid emulsion is made by dissolving specified amounts of an amine-type emulsifier in specified amounts of (a) the bitumen, and (b) water containing anhydrous HCl, heating the solutions and then mixing them.
