Abstract: 247,071. Coslett, T. W. June 36, 1925. Coating.-In a process for treating iron and steel to prevent oxidation or rusting as described in Specifications 8667/06 and 28131/09, a boron compound is added to the solution referred to. care being taken to select a boron compound which will not affect detrimentally the coating produced as for example boric acid or a borate such as borax. In one example, 2 ozs. of pasty or concentrated acid zinc phosphate and 1¢ ozs. of powdered or crystalline boric acid are dissolved in one gallon of water. Before subjecting the articles to treatment, they are immersed for a short period in a hot or cold solution of boric acid. The formation of the deposit may be assisted by passing an electric current through the solution.
Patent GB-421122-A (GB)
Title: Improvements in the colouration of textile materials
Filed: 1933-06-09
Abstract: Azo dyes, forming on the material; cellulose esters or ethers, dyeing.--Textile materials made of or containing cellulose esters or ethers are impregnated with an enolic coupling component, for the production of azo dyes on the fibre, by immersion in an aqueous bath containing caustic alkali, a sugar, preferably a reducing sugar, and the component.  The presence of the sugar enables the use of a greater proportion of caustic alkali without saponification of cellulose ester materials.  Specified sugars are cane sugar, dextrose, levulose, galactose, invert sugar, corn syrup and a crude sugary mixture obtained by hydrolysis of wood. The use of a reducing sugar is specially advantageous when the diazo component, applied simultaneously with the coupling component, is a readily oxidizable amine, such as 4 : 4<1>-diaminodiphenylamine.  The sugar may also be used in conjunction with another reducing agent, such as phenylhydrazine-sulphonic acid.  Specified coupling components are the arylides of oxycarboxylic acids of the benzene, naphthalene or carbazole series, b -ketoacidyl derivatives of aromatic amines, e.g., diacetoacetyl-o-tolidine, b -naphthol, and 2 : 3-and 1 - 7-acidylamino-naphthols.  The impregnation may be facilitated by incorporating swelling agents, such as alcohol, in the baths.  The following examples are specified.  (1) A cellulose acetate yarn is dyed a deep crimson, fast to washing, by treatment in a bath at about 70 DEG  C., containing caustic soda, glucose and turkey red oil dispersions of 5-nitro-2-aminoanisol and the 2<1>-naphthylamide of 2 : 3-oxynaphthoic acid, rinsing, treatment in a bath containing sodium nitrite and acetic acid, again rinsing, treatment in a very dilute solution of soda ash, and soaping at about 75 DEG  C.  (2) A cellulose acetate knit fabric is dyed a full lemon-yellow by treatment in a bath at about 75 DEG  C. containing caustic soda, corn syrup, turkey red oil, 2 : 5-dichloraniline and diacetoacetyl-o-tolidine, rinsing, treatment in a bath containing sodium nitrite and formic acid, and soaping as in (1).  (3) A cotton-cellulose acetate woven fabric is dyed first with Indanthrene blue 5G by the process of Specification 262,506, [Class 15 (ii)], to colour the cotton a fast blue and the cellulose acetate is then coloured a fast golden brown by treatment on a jig at 75--80 DEG  C., with a liquor containing caustic soda, invert sugar, turkey red oil, p-nitraniline and the anilide of 2 : 3-oxycarbazole-carboxylic acid, rinsing, treatment in a bath containing sodium nitrite and acetic acid and soaping at about 75 DEG  C.  The Provisional Specification describes also the use of the process for dyeing textiles made of or containing animal fibres and the use, in place of the sugars, of polyhydric alcohols, e.g. mannitol, aliphatic or other amino-acids, di-or poly-peptides, e.g., glycyl-glycine and crude products obtainable by hydrolysis of wool and other protein material.

Abstract: 579,586. Helicopter rotors. FAIREY AVIATION CO., Ltd., and FORSYTH, A. G. Aug. 31, 1944, No. 16586. [Class 4]. A helicopter rotor is driven by internal-combustion engineunits mounted at the outer ends of arms carried by the rotor head, and the rotor blades are mounted on tubular shafts surrounding the arms, .the inner ends of the shafts being mounted in sockets in the rotor head by means of bearings which allow pitch change movement of the blades and at the same time take up loading due to the centrifugal force on the blades. By this means the centrifugal force on the engine units is transmitted to the rotor head independently of the blades and change of pitch may be effected without undue effort. In one form, Fig. 1, a rotor shaft a is mounted in bearings (not shown) and carries keys b engaging slots in the heads d of arms e on which engine units f are mounted. The keys and slots are formed with spherical surfaces so that the rotor may tilt about the centre c. The outer surfaces of heads d abut the spherical inner surface of a hollow rotor head g which is formed with sockets h for rotor blades carried by tubular shafts m surrounding the arms e. The shafts m are rotatable in the sockets h by means of thrust bearings k, and bearings n are provided between the shafts and arms e. In another form, Fig. 2 (not shown), the shaft a is fixed and the heads d of arms e are mounted on the shaft by means of a spherical ball-race to allow tilting of the rotor. In a further form, Fig. 3 (not shown), the heads d and rotor head g are mounted on a fixed rotor shaft a by means of a sleeve and ball bearings, tilting of the rotor being allowed by a universal mounting of the shaft.

[Also in Group XL (c)] In a double side-band multi-channel carrier system in which the channel filters BP2 of the receiver are arranged between a group amplifier EV and a channel amplifier MV, the channel amplifier MV is used simultaneously for amplification of the channel side-bands and the detected L.F. signal, i.e. reflex amplification, and also for the generation of oscillations for use in the system. In the system, Fig. 1, the " send " carrier is generated in the amplifier MV and is transmitted to line F with the sidebands. Ringing and dialling signals are sent by keying the carrier at K. Incoming carrier signals at terminals E of amplifier MV, Fig. 3, after amplification in valve V and detection in the circuit Dem, are applied to the grid of valve V for L.F. amplification before being passed to the receiver via terminals A3. Incoming signalling currents are repeated by a relay ER in the detector output circuit and the " send " carrier is generated by the grid-anode coupling between the tuned primary W1 and secondary W2 of a transformer U1. Opposed rectifiers X serve to limit the amplitude of the oscillations which are made available at terminals A1 by a winding W3 of the transformer.
