Patent GB-402371-A (GB)
Title: Improvements in fuel injection devices for internal combustion engines
IPC: F02M57/02
Filed: 1933-07-26
Abstract: 402,371. Oil engines. KNIGHT & HALE, Ltd., J., and WHITAKER, J. E., Victoria Works, Denton, Lancashire. July 26, 1933, No. 21022. Addition to 352,298. [Class 7 (iii).] A fuel injector, in which a cam-operated hollow plunger in a stationary cylinder forces fuel into a combustion chamber when the fluid pressure of the fuel opens an injection valve centrally disposed in the plunger and seated by a spring located between the plunger and the valve to urge them apart, the fuel being regulated by a valve through which excess is returned to the supply port, as described in the parent Specification, is modified so that the injection valve is seated by a spring disposed at the fluid pressure end of the plunger. A pump cylinder G disposed in a stationary cylinder or casing A guides a plunger B in which is located the rod of an injection valve C. After a cam operated rocker arm M has depressed the plunger B, a spring F raises it to draw fuel through a port a past a non-return valve H to a chamber R surrounding the injector valve C which is held on its seat by a spring E disposed between the pump cylinder G and a collar e on the valve. Depression of the plunger B builds up pressure in the chamber R sufficient to cause the lifting of the valve C, the fuel being then injected into the engine cylinder. The amount of fuel delivered is controlled by a valve K in communication with the chamber R through a non-return valve and opened for a predetermined period, which is adjustable, by a tappet m<2> associated with the rocker arm M. Fuel thus rejected flows through a port p<1> to the inlet passage which also receives through ports f any fuel that has leaked past the plunger B and stem of the valve C.

Title: Manufacture of cellulose derivatives and of shaped structures therefrom
IPC: C08B11/04
Filed: 1936-01-24
Abstract: Alkali-soluble water-insoluble hydroxyalkyl ethers of cellulose p are made while maintaining the temperature substantially below 15 DEG C., for example, at 10--5 DEG  C. or below, during the whole or the greater part of the reaction period.  The caustic alkali solution for the preparation of the alkali cellulose must contain less than 30 per cent caustic soda or a chemically equivalent percentage of another caustic alkali, and the proportion of the hydroxyalkylating agent must not be larger than and is preferably smaller than one mol. per one C6H10O5 unit or even 2 or 4--5 of such units.  The cellulose ethers so obtained contain less than one hydroxyalkyl group per one C6H10O5 unit.  By the use of low temperatures for the etherification, cellulose ethers are obtained which give shaped articles of improved dynamometric properties, and such articles after coagulation and washing contain a reduced proportion of water.  In addition to the employment of temperatures below 15 DEG  C. in the etherification reaction, one or more of the following stages may also be carried out at similar low temperatures; (1) preparing the alkali cellulose; (2) shredding the alkali cellulose; (3) maturing the alkali cellulose; and (4) after-ripening of the reaction mass from the etherification. Mixed ethers may be obtained by employing a mixture of hydroxy alkylating agents, and by including with the hydroxyalkylating agent or agents a reagent adapted to introduce alkyl or fatty acid residues.  The cellulose ethers obtained by the process may be brought into solution in caustic alkali by stirring, kneading, &c., assisted by lowering the temperature to below 0 DEG  C., for example, to -5 DEG  C. to -10 DEG  C., or the ethers may be xanthated and similarly brought into solution for working up into shaped articles. For working up the cellulose ethers or ether xanthates into artificial threads, staple fibre, films, plates, plastic masses, adhesives, cements, finishes, coatings, dressings, &c., the solution is brought into the desired shape or form and then is coagulated with any bath capable of coagulating viscose, and such bath or a later bath may have a plasticizing effect on the coagulated products; alternatively, the solution may be coagulated by an alkali carbonate.

Title: Improvements in the manufacture and production of 1.4-diamino-2-aryloxyanthraquinone-3-sulphonic acids
IPC: C09B1/54
Filed: 1932-07-28
Abstract: 1 . 4 - diamino - 2 - aryloxyanthraquinone - 3 - sulphonic acids are prepared by reacting 1 . 4 - diamino - 2 . 3 - dihalogenanthraquinones with phenols or naphthols and salts, preferably water-soluble inorganic salts, of sulphurous acid in the presence of metal compounds having acid-binding properties but the alkalinity of which is neither sufficient to split off or replace by hydroxy groups the halogen atoms present in the molecule of the initial material nor sufficient to have a saponifying action on the aryloxy group introduced.  Such acid-binding agents are incapable of forming salts with phenols or naphthols; in addition to these properties they may possess oxidising properties.  Suitable metal compounds are alkali metal perborates, oxides and hydroxides of metals other than alkali metals or alkaline earth metals, such as pyrolusite, lead peroxide, magnesium oxide, zinc oxide. Advantageously about 10 molar proportions of the phenol and 2--3 molar proportions of the sulphurous acid salt is reacted with 1 molar proportion of the anthraquinone compound; increased pressure and temperatures of 120--160 DEG  C. are favoured.  In examples (1) 1 . 4 - diamino - 2 . 3 - dichloranthraquinone is heated in an autoclave with phenol, sodium sulphite and pyrolusite at 130 DEG  C.; pyrolusite may be replaced by lead peroxide, or magnesia when a reacting temperature of 140 DEG  C. is employed; 1 . 4 - diamino - 2 . 3 - dibromanthraquinone may be similarly treated; (2) 1 . 4 - diamino - 2 - 3 - dichloranthraquinone is heated in an autoclave with m-cresol, sodium sulphite and pyrolusite to 140 DEG  C.; m-cresol may be replaced by p-chlorphenol or b -naphthol.
