Title: Improvements in window fasteners for securely locking windows
IPC: E05F11/00
Filed: 1921-10-27
Abstract: 189,952. Macdonald, J. Oct. 27, 1921. Hatch fastenings.-A hatch fastening comprises a worm-wheel cut away across a chord and having a slot to engage a stud. The worm-wheel 2 is pivoted at 4 on a plate 1 on the hatch or coaming so that in the " open " position its edge is flush with the division between the hatch and coaming. A double-threaded worm 3 turning in brackets 6 on the plate 1 engages diagonal teeth on the wheel 2 and can turn to move the wheel on its pivot so that a stud 10 on the coaming or hatch is engaged in the slot 9 in the wheel, to fasten the hatch. The spindle 5 of the worm may be cranked to facilitate turning, or it may be squared as at 7 to receive an operating key. A notch 12 in the cut-away edge of the wheel engages a stud 13 on the plate 1 to limit its unfastening motion and align the straight edge with the edge of the hatch.

Title: Manufacture of composite calcium sulphate-titanium oxide pigments
IPC: C09C1/00
Filed: 1930-09-23
Abstract: In the preparation of composite titanium oxide-calcium sulphate pigments made by heating and hydrolizing a mineral acid solution of titanium salts containing a suspension of calcium sulphate upon which the titanium oxide is precipitated, the calcium sulphate is made by adding quick or slaked lime, calcium carbonate or other calcium compound to concentrated sulphuric acid.  An aqueous slurry of lime is added to 78 per cent sulphuric acid, and the resulting pulp of calcium sulphate is mixed while still hot with an acid solution of ilmenite containing 6 per cent of TiO2. The mixture was boiled and the resulting precipitate filtered, washed with a small amount of water and ignited at 700-1200 DEG  C. Pigments containing 30 and 75 per cent of titanium oxide are described.  By this process the pigment is made free from iron. The form of calcium sulphate used is stated to be anhydrite, which partly dissolves in acid solutions, yielding a suspension of fine particles whereby the formation of colloidal titanium salts is prevented.

Title: Treatment of cellulosic fibres, threads and yarns
Inventor: SLOAN FREDERICK RICHARD WILFRE
IPC: D06M15/39
Filed: 1960-03-23
Abstract: Cellulosic fibres, threads and yarns, e.g. viscose rayon, are treated with an aqueous medium containing a film forming polyol, e.g. polyvinyl alcohol, or alternatively polyvinylacetate, (2) a cross linking agent which is an aldehyde which in the presence of water exhibits a functionality of at least two or a water soluble derivative of the aldehyde which in the presence of water exhibits a functionality of at least two and will not undergo homopolimerisation to a water-insoluble resinous condition and (3) a water soluble polyester which comprises structural units connected by ester linkages and which contains free acidic groups, so that fabrics woven or knitted therefrom possess drip-dry crease-resisting properties. Suitable cross linking agents are formaldehyde, dimethylol ethylene urea, glyoxal, acetals of a dialdehyde with a monohydric alcohol or of a monoaldehyde with a polyol, and hemi-acetals.  The polyester may be that of sebacic, maleic, succinic or phthalic acid or an anhydride thereof with a glycol or glycerol.  After treatment the fibres, threads or yarns may be dried and if necessary heated at an elevated temperature. When treating fibres relative movement of the fibres may be maintained during drying by passing continuous filament tow over rollers in a hot flue drier or by drying staple fibres in a stream of hot air.  Fine fibres may also be treated with a surface active agent, e.g. methyl melaminestearamide, which will produce water repellancy.
