Abstract: 457,212. Fountain pens. SPOT PEN CO., Ltd., Tudor Grove, Well Street, Hackney, and JOHNSON, W. F., 13, Merrick Square, Trinity Street, both in London. July 22, 1935, No. 20767. [Class 146 (iii)] In a self-filling fountain pen of the type in which a sac is deflated by a presser-member operated from a stud movable longitudinally in the upper end of the barrel, the mechanism comprises a flexible bar which is adapted to be bent by an element extending longitudinally in the barrel and adapted to be moved longitudinally by screw means. The stud 5 is rotatably attached to a cap 8 screwing on the end of the barrel and prevented from disconnection by a head 6 on the inner end of the stud. The end of a steel bar 11 is bent to U-section and wedged into the end of the stud, and the bar is cranked so that it can lie along the wall of the barrel. A flat flexible steel bar 14 is formed with a reduced lower end which engages in a slot in the bar 11, and with a rounded upper end which passes through an aperture in the cranked end of the bar 11 and engages the rear end of the barrel. Unscrewing of the cap withdraws the stud 5 and bar 11 and causes the bar 14 to bend inwardly. A presser-bar 18 is attached to the bar 14, and when the bar 14 is flexed, the bar 18 is drawn inwardly so as not to rub the sac against the end of the nib-section. Instead of securing the stud to the cap rearward movement of the stud can be effected by a spring.

Abstract: 506,783. Treating textiles; waterproofing. TOOTAL BROADHURST LEE CO., Ltd., CORTEEN, H., and WOOD, F. C. Aug. 27, 1937, No. 20861/38. Divided application. [Classes 2 (ii) and 15 (ii)] (Also in Group VIII] Textile materials which have been rendered water-repellent by impregnation with an organic nitrogen compound which can be made from a tertiary nitrogen base, formaldehyde and a fatty alcohol, amine, amide or urethane containing at least ten carbon atoms, are treated with a neutral or alkaline swelling agent. The handle, strength and wearing properties are thereby improved. Suitable swelling agents are sodium and potassium hydroxide, cuprammonium hydroxide, quaternary ammonium bases, sulphonium bases, caustic alkalies with carbon bisulphide, and caustic alkalies with ethylene oxide for cellulosic materials, acetone and water for cellulose acetate materials, and caustic alkalies or ammonia for wool and silk materials. The materials may also be subjected to further textile finishing processes such as delustring, rendering crease-resisting. or shrinking. In an example, linen is made water-repellent by treatment with octadecyloxymethylpyridinium chloride or N - car - bomethoxyheptadecylaminomethylpyridinium chloride, wetted, and immersed in caustic soda solution. The swelling may also be applied to a material which has been made waterrepellent and impregnated with resin or a reactive aldehyde. In another example, linen is rendered water-repellent by means of octadecyloxymethylpyridinium chloride, immersed in caustic soda solution, impregnated with a lightly condensed solution prepared by refluxing urea with formaldehyde and ammonia, to which after cooling tartaric acid is added, and heated.

Patent GB-655439-A (GB)
Title: Improvements relating to the refining of glycerine
IPC: C11D19/00
Filed: 1948-08-10
Abstract: Glycerine which has been obtained by the transesterification of fatty material by a low molecular weight alcohol first under alkaline and then under acid conditions is purified by neutralizing the acidic glycerine with an alkaline earth carbonate followed by treatment with an alkaline earth halide and removal of insoluble material.  The acidic glycerine may be neutralized either before or after separation from the acidic esterification mass.  The halide-treated glycerine may be extracted with methanol, ethanol, propanol, or butanol, or with acetone, or it may be dissolved in one of these alcohols and acetone added until a precipitate just begins to form, heated, insoluble matter removed, and the solvent distilled off.  The glycerine may finally be distilled under reduced pressure or co-distilled with a mineral oil of similar boiling point.  The process is normally conducted under relatively water-free conditions. If the fatty starting material has a relatively high acid value above 10, the amount of water produced is appreciable and the transesterification reaction is carried out so that water of reaction is continuously removed by refluxing or mechanical separation. Alkaline earth halides which may be used on the chlorides, fluorides and bromides of calcium, barium, and strontium or mixtures thereof, but barium chloride is preferred. The amount of halide added is sufficient to convert the sodium salts present in the glyceride layer into halides.  According to examples, peanut and coconut oils and hydrogenated fish oils are transesterified with methanol first in presence of caustic soda and then in presence of sulphuric acid and the acidic glycerine or the acid mass then treated with barium, calcium and strontium carbonates.  The glycerine layer is then heated with barium chloride or calcium fluoride to convert the sodium salts present into the neutral halides, the glycerine extracted with methanol, insoluble matters removed and the glycerine finally distilled under reduced pressure.  Specification 647,174 is referred to.
