Title: Improvements in the stretching of artificial filaments, ribbons and like materials
IPC: D01D5/12
Filed: 1939-09-27
Abstract: 535,094. Artificial filaments &c. DREYFUS, H. Sept. 27, 1939, No. 26738. [Class 2 (ii)] Artificial filaments, yarns, ribbons, strips, and like materials having a basis of an organic, derivative of cellulose are subjected to a stretching operation while under the influence of an aqueous emulsion of an organic solvent or swelling agent for the cellulose derivative, e.g., methylene chloride, ethylene chloride, or chloroform. The disperse phase in the emulsion may consist entirely of the water-immiscible swelling agent or it may be a solution of the swelling agent in a water insoluble liquid such as benzene, toluene, xylene, benzine, petrol ether, kerosene, carbon tetrachloride, trichlorethylene, or perchlorethylene. The emulsions may be prepared with the aid of soaps such as alkali metal and ammonium soaps, and ethanolamine and other organic soaps, particularly soaps of higher fatty acids, sulphonated fatty alcohols, alkylated naphthalene sulphonic acids, e.g., cetyl naphthalene sulphonic acid, and the product obtained by sulphonating a mixture of naphthalene and castor oil. The stretching may be effected at ordinary or elevated temperatures and pressures. The materials may be stretched in hank form, or while travelling between stretching rollers. The emulsion may be applied by dipping, or spraying, or by application from the surface of a roller which dips into a bath of the emulsion. The stretching increases the tenacity of the materials. To improve the extensibility the stretched materials may be subjected to the action of shrinking agents and preferably allowed to shrink. Shrinking may take place continuously with the stretching operation. The materials treated may be of cellulose acetate or other cellulose ester or ether. In an example, dryspun cellulose acetate yarn is withdrawn from bobbins and passed to two successive sets of three rollers, the second roller of each set being disposed below the level of the first and third. The lower roller of each set is immersed in a mixture of methylene chloride and petroleum dispersed in water with the aid of ammonium stearate. The yarn is passed over and between the rollers and is then passed through the air to a draw roller which stretches it about 100 per cent. The yarn passes around rollers immersed in water containing ammonium stearate, then through a bath of water, and a pair of nip rollers and it is then dried. Specifications 389.823, and 525,484 are referred to.

Title: An improved process for the production of mono- and/or di-ammonium phosphate or of mixed fertilisers containing same in granular form
IPC: C05B7/00
Filed: 1931-09-25
Abstract: Granular mono-ammonium phosphate or mixed fertilizers containing it are obtained by introducing an excess of moist gaseous ammonia into a phosphoric acid solution, to which other fertilizers may have been added, heated to above 130 DEG  C., say 130-180 DEG  C., to produce a melt which will solidify on cooling and granulating the melt before or after the cooling.  According to a modification, the other fertilizers are added to the melt after the treatment with ammonia, if necessary with suitable regulation of the temperature, e.g. a further heating to 170-190 DEG  C.  The additional fertilizers referred to are potassium salts such as potassium chloride or sulphate, ammonium salts, nitrates and phosphates and finely divided insoluble fertilizers such as di-calcium phosphate.  The granular mono-ammonium phosphate or fertilizers containing the same may subsequently be treated with moist gaseous ammonia to convert the mono-wholly or partly into the di-ammonium phosphate.  The melts obtained may be cast into flat cakes or rolled by cooling rolls to flat cakes which can be ground to granules of the required size, or the melt may be broken up by being sprayed on to a rotating drum to obtain hard, uniformly spherical particles.  The granulated mono-ammonium phosphate may be mixed with other fertilizing substances such as potassium, ammonium or calcium salts, nitrates or phosphates. Examples are given.ALSO:Granular mono-ammonium phosphate or mixed fertilizers containing it are obtained by introducing an excess of moist gaseous ammonia into a phosphoric acid solution to which other fertilizers may have been added, heated to above 130 DEG C., say 130-180 DEG  C., to produce a melt which will solidify on cooling, and granulating the melt before or after the cooling.

Abstract: 207,660. Masson, R. D., and Engel, H. Oct. 7, 1922. Purifying oils.-In apparatus for purifying oils by steam and working under reduced pressure the lowest point in the pipe supplying oil to the purifier is a greater vertical distance below the oil outlet from the purifier than the length of a barometric column of the hot oil, whereby destruction of the vacuum in the purifier is prevented. In the apparatus shown, impure oil is passed from a tank 1 through a constant-level cistern 2, a pipe 4, a heat-exchanger 6, a pipe 7, heaters 8, 10, and a pipe 11 to a purifier 3 down which it falls aganst a current of superheated steam admitted by a pipe 23. The lower part of the pipe 4 is immersed in water in a well 5 to a depth which is greater than the barometric column. The treated oil leaves the purifier by a pipe 12, is passed through the heat-exchanger 6, a U-pipe 13 in the well 5, a cooler 14, a pump 15 and a pipe 16 to a tank 17, and is afterwards run through a pipe 18, a filter-press 19, and a pipe 20 to a storage tank 21.

Title: Improvements relating to the operation of internal combustion engines
Filed: 1957-08-29
Abstract: In a method of operating an internal combustion engine which is operating on a fuel having a total sulphur content of at least 0.1% wt., the cylinder lubrication is effected by a mobile lubricating composition which comprises a lubricating oil having dissolved therein up to 40% by weight of the composition of a polymeric aluminium compound OnAlmXp, where X is a group RCOO-, R being an aliphatic or aromatic hydrocarbon or substituted hydrocarbon radical, m, n, and p are integers, m is not less than 2, and the ratios m/n and m/p are within the ranges 0.75 to 2 and 0.5 to 3 respectively. The Groups X in the molecule may be the same or different.  Such compositions are described and claimed in Specification 853,334. Where the amount of additive would normally convert the oil to a grease, mobility may be preserved by the addition of an anti-gelling agent, e.g. 8-hydroxyquinoline.  Preferred oils are SAE 30, 40 and 50 mineral oils.  The Groups X are preferably derived from benzoic or salicylic acids or C12-C20 aliphatic monocarboxylic acids, e.g. stearin or olein.  The preferred additives have the formula (I) O3Al3X3, where the groups X may be the same or different.  The additives may be prepared either by heating aluminium alcoholates with water and carboxylic acids, preferably in an inert non-volatile diluent such as lubricating oil, or by heating the aluminium alcoholates with carboxylic acids alone to form acyloxy aluminium alcoholate compounds and further heating the latter.  In examples, additive compositions consisting of (i) 40% wt. light lubricating oil and 60% wt. of a material of formula I wherein 2/3 of the groups X are derived from stearin and 1/3 from benzoic acid, and (ii) 50% wt. isopropyl oleate and 50% wt. of a material of formula (I) wherein all the groups X are derived from olein, are added to SAE 30 mineral oil of (a) 140 secs. Redwood I/140 DEG F. and V.I.65 and (b) 160 secs. Redwood I/140 DEG F. and V.I.95 respectively.  In the first case 1/2 % of 8-hydroxyquinoline was added to prevent grease formation and the resulting lubricant composition was compared with (a) a mixture of calcium C16-C18 fatty acid soap and calcium carbonate in the same base oil and (b) a water-in-oil emulsion containing calcium acetate in the aqueous phase.
