Title: Improvements relating to electric fuses for projectiles
IPC: F42C17/04
Filed: 1927-07-14
Abstract: 276,965. Rheinische Metallwaarenund Maschinenfabrik. Sept. 1, 1926, [Convention date]. Ordnance design. - Electric contacts or an electric coil or like magnetic field is provided on a gun to transfer to the fuze of a projectile at the moment of its discharge an amount of electrical energy which determines the time of operation of the fuze. Further electric energy may be imparted to the fuze by a battery or generator in the projectile. As shown, a coil c, Fig. 1, is arranged with a gas deflector b at the muzzle of a gun a, and is connected through an adjustable resistance d and a current indicator e to a source of current f; and the projectile g, Fig. 2, is surrounded by a coil h connected to another coil i and through a switch t to a condenser k. When the projectile is discharged, the coil h in passing through the coil c is energized and loads the condenser k through the switch t which is atl that period closed. The coil h also supplies current to the solenoid i which sucks its core l up, lifting a lever o with a rack p, and causing a switch member q carried by the rack p to be swung into operative position. During the flight of the projectile after the coil h has ceased to be influenced by the coil c and the switch t has become open, the rack p is retracted with the lever o and solenoid core l by a spring m; at the end of this movement which is delayed by gearing u and a vane v, the switch member g closes the circuit s<1> of the condenser k through the electric igniter r. The strength of the current in the coil c determines the throw of the rack p and therefore the time the fuze takes to operate. An additional adjustable resistance d<1> may be provided to control the strength of this current from a distance.

Title: Improvements in or relating to the manufacture of azo dyestuffs
IPC: C09B56/08
Filed: 1934-06-28
Abstract: Azo dyes are made by using as diazo components amines of the general formula <FORM:0444875/IV/1> in which R together with the adjacent carbon atom represents a mono- or polynuclear heterocyclic ring system with a tertiary double bonded nitrogen atom which is preferably in a  or g  position to the carbon atom which carries the side chain, X = H or any organic residue linked to carbon and R<1> is an aromatic residue which may be substituted (e.g. by halogen, nitro, hydroxy, or alkoxy groups).  The dyestuffs have good substantivity and may be used for mixed fabrics of cellulose and animal fibres. They are fast to acids and alkalis and may be developed on the fibre. The components may be used in the ice-colour process, preferably in stabilized form, with b -naphthol, 2 : 3-oxynaphthoic acid and acetoacetic arylides.  Monoazo dyes from the above diazo components and the usual middle components are useful for developing dyeings on the fibre and may be used in the form of stable diazo preparations. In examples the following dyestuffs are described: (1) m-nitrobenzaldehyde is condensed with a mixture of pyridine bases in presence of acetic anhydride, the product is reduced and the mixture of m<1>-amino-a - and g -stilbazoles thus obtained is diazotized and coupled with J acid; the dyestuff (reddish orange on cotton) may be diazotized on the fibre and developed; (2) p<1>-amino-g -stilbazole --> a -naphthylamine --> (on cotton) b -naphthol (violet); (3) m<1>-amino-a -stilbazole --> 1-naphthylamine-6-sulphonic acid --> g -acid (bluish grey to black on cotton from a salt bath which may be diazotized and developed); (4) and (5) cotton is impregnated with the b -naphthalide of 2 : 3-oxynaphthoic acid and developed with diazotized m<1>-amino-a -stilbazole or the diazotized dyestuff m<1>-amino-a -stilbazole --> a -naphthylamine (scarlet red and violet).  Other components specified are the reduced condensation products from o-, m- or p-nitrobenzaldehyde, o- or p-chloro-m-nitrobenzaldehyde, nitroanisaldehyde or nitropiperonal and a - or g -picoline, lutidine, collidine, a -benzylpyridine, chinaldine, m  - alkylbenzimidazole, m  - alkylbenzoxazole, m -alkylbenzthiazole, 1-phenyl-3 : 5-dimethyl - pyrazole, 4 : 6-dimethyl- or 2 : 4 : 6-trimethyl-pyrimidine, 2 : 5-dimethylpyrazine, 9-methylacridine or 9-methylphenanthridine or sulphonic acids of the latter products., Compounds of the above type may also be obtained by condensation of m- or p-nitrocinnamic aldehyde with acetoacetic or oxalicacetic ester in presence of ammonia (Hantzsch's pyridine synthesis), oxidation of the hydropyridine derivative to the pyridine compound, if necessary saponification of the carboxylic acid ester group and finally reduction of the nitro group, or by condensation of m- or p-nitrocinnamic acid with o-phenylenediamine, o-aminophenol or o-aminothiophenol and reducing the nitro benzimidazole, benzoxazole or benzthiazole compounds.

Title: Process for producing acyloxysilicon compounds
IPC: C07F7/18
Filed: 1957-06-19
Abstract: Acyloxy silicon compounds of the formula: X (RXSiO)n Si X2 R, in which n is O, 1 or 2, X is an alkyl or acyloxy radical, at least one X being acyloxy, and R is an alkyl radical, are prepared by heating an alkylsiloxane with an acyloxy compound of the formula R11COOR111, where R11 is an alkyl radical of 1 to 17 carbon atoms, an aryl radical or a hydrogen atom, and R111 is hydrogen or OCR11, in the presence of an acid catalyst.  The alkyl siloxane may be cyclic, e.g. trimer or tetramer, linear or crosslinked and may be homo- or co-polymeric.  As acyloxy reactants are mentioned such acids as benzoic and stearic acids, but preferred are the aliphatic acids containing 2 to 7 carbon atoms or their anhydrides, particularly acetic acid and/or anhydride.  When acids are used the water which is formed should be continuously removed from the reaction.  This may be done azeotropically with an organic liquid e.g. cyclic hydrocarbons. Temperatures may vary from 50  DEG  to 235  DEG C.  The specified catalyst is sulphuric acid.  In the examples: (1) octamethylcyclotetrasiloxane is heated with acetic acid and anhydride and with H2SO4 as catalyst, the catalyst neutralised with potassium acetate, to give, after stripping, fractionating &c., the compounds diacetoxydimethyl silane, acetoxydimethylsiloxyacetoxy dimethyl silane and bis (acetoxydimethylsiloxy) dimethylsilane; (2) an ethylpolysiloxane is reacted with butanoic acid to give mainly the compound (C3H5COO)3 SiC2H5.
