Abstract: The invention comprises dyes of formula:  <FORM:0844216/IV (c)/1> where R1 is an alkyl group of 1-3 C atoms, R2 is H, Hlg or Me, R3 is H, Hlg or alkyl, R4 is H, Me or Et, B is a ketomethylene residue bound to the azo link in a position vicinal to the enol group or an aromatic residue bound to the azo link in a position vicinal to the OH group, X is H or Hlg, alkyl, -NH aryl or a group where Y1 and Y2 are the same or different and are each H, alkyl or oxyalkyl.  The invention includes chromium, cobalt, iron and nickel complexes of one or two dyes of the above formula or of one of the above dyes and one of formula HO-A-N= N-C-OH where A and C are the same or different and are each an organic group bound to the azo link in a position vicinal to the OH group and may bear Hlg, alkyl, alkoxy, nitro or -SO2 -N(X1) 2 groups where X1 and X2 are the same or different each being H or alkyl.  The metalfree dyes are made by diazotising an appropriate aniline derivative and coupling with a compound of formula HB(X) OH. Indicated as coupling conponents are 5-pyrazolones, 2, 4-dihydroxyquinolines, phenols and naphthols, a variety of which are specified. Metallisation is effected in conventional fashion.  The metal products colour proteinaceous substances e.g. leather and hair and polypeptide fibres such as wool, silk, casein, superpoly-amide and -urethane fibres.  Weakly alkaline, neutral or weakly acid baths are preferred.  Examples and a table are provided illustrating the preparation of the dyes and their use in dyeing processes in which a variety of shades, e.g. yellow, red, grey, green and brown are obtained on wool.  Specifications 637,404, 727,528, 745,641 and 771,309 are referred to.

Hulling, husking, and decorticating. - A machine for removing the pericarp from palm-nuts &c., of the type described in Specification 12655/15, has the springs C, Fig. 6, which project from the surface of the drum B, helically arranged. The drum is built up of discs B' having a flange b<5> surfaced with stabbed metal b<6>, each disc being slit and bent to form one turn of a helix. Through the slot b<10> between adjacent discs project the springs C, mounted upon studs D which form distance-pieces between the discs. Adjacent discs have a slight relative angular displacement. The nuts &c. are fed from a hopper F by one or more reciprocating slides G', actuated by a crank or cranks g<5> on the shaft g<7> driven by friction gearing g<13>, g<14> from shaft b', the ratio being adjusted by sliding the disc g<13> on the shaft g' by means of a lever g<22> operated by a hand wheel. The nuts pass along longitudinal channels formed by plates h<1>, h<2>, h<3>, Fig. 3. The surface of the drum B is cleaned by a brush E which moves, at the point of contact, in the same direction as and at a greater speed than the drum, the action turning the springs C down into the slots b<10>, the length of the recesses b<16> in which the ends c<2> of the springs are anchored allowing a limited movement, the amount of which can be varied by bending the tongue b" at the end of each recess b<16>. The frame of the machine is of tubular bars, and may be hinged at a<9> to allow of the drum being exposed. It is supported on detachable legs, and wheels may be fitted for transport.

Patent GB-553960-A (GB)
Title: Improvements in coloured cellulose ester or ether materials
IPC: C09B43/28
Filed: 1941-12-05
Abstract: 553,960. Dyes; dyeing textiles &c. ARGYLE, C. S. Dec. 5, 1941, No. 15693. [Classes 2 (ii), 2 (iii) and 15 (ii)] Cellulose ester or ether materials are coloured with an aromatic azo compound containing at least one nitro group and one etherified phenolic hydroxyl group and free from salt-forming groups such as sulphonic, carboxylic, free phenolic and non-acidylated amino groups. Specified etherifying radicles are methyl, ethyl, isopropyl, #-hydroxyethyl, and γ-chloro-#-hydroxypropyl. The coloration may be effected by applying the dyes to the materials in aqueous dispersion or in solution in organic solvents or by incorporating the dyes in the solutions from which filaments, straws or films of the materials are shaped. In examples, a cellulose acetate fabric is dyed yellow fast to light and to alkaline washing treatments with the dyestuffs, (a) 4- chloro - 2 - nitro - 4<SP>1</SP> - ethoxy - azo - benzene and (b) 4 - methoxy 3 - nitro - 4<SP>1</SP> - acetylamino - 1:1<SP>1</SP> - benzene - azo - naphthalene. The processes and products claimed in Specification 550,805 are disclaimed. Azo dyes of the above type are obtainable by etherification of the corresponding azo compounds containing free phenolic groups, e.g. with an alkyl halide such as methyl or ethyl chloride, a dialkyl sulphate such as dimethyl or diethyl sulphate, an alkylene oxide or an alkylene halohydrin. Specified azo compounds so etherified are 2- or 4-nitro - 4<SP>1</SP> - hydroxy -azobenzene, 3 - nitro - 3<SP>1</SP> - chloro - 4<SP>1</SP> - hydroxy - azo - benzene, 4 - nitro - 51 - methyl - 21 - hydroxy - azo - benzene, 2 - nitro - 4 - chloro - 4<SP>1</SP> - hydroxy - azo - benzene, 4 - nitro - 2<SP>1</SP> - chloro - 4<SP>1</SP> - hydroxy - azo - benzene, 4 - nitro - 3<SP>1</SP> - methyl - 4<SP>1</SP> - hydroxy - azo - benzene, 4 - chloro - 3<SP>1</SP> - nitro - 4<SP>1</SP> - hydroxy - azo - benzene, 4 - nitrobenzene - azo - α - naphthol, the amide or ethyl ester of 3<SP>1</SP> - nitro - 4<SP>1</SP> - hydroxy - azo - benzene - 4 - carboxylic acid, p - nitrobenzene - azo - benzene - azo - phenol and p - nitrobenzene - azo - benzene - azo - α - naphthol. Alternatively, salt-forming groups in corresponding azo compounds may be converted into non-salt-forming groups ; thus an amino group as in 4 - methoxy - 3 - nitrobenzene - azo - α - naphthylamine, may be acylated, e.g. acetylated or propionylated, or a carboxylic acid group may be esterified or converted into the acid amide group.

Title: Improvements in or relating to electromagnetic waveguides
IPC: H01P1/163
Filed: 1945-06-20
Abstract: 597,251. Wave-guides. ALLEN, W. D. June 20, 1945, No. 15789. [Classes 40 (iii), and 40 (v)] A device for effecting transformation of the mode of wave propagation in a wave-guide comprises a member of dielectric material having a dielectric constant different from that of the dielectric medium of the guide, placed in the guide, and so shaped and dimensioned that a phase change is imparted to a selected portion of the wave, so that upon recombination of the two wave portions, the desired mode change is effected. Fig. 5 shows an arrangement for changing an E01 wave in a circular guide 10 into an H11 wave in a circular guide 15. A semicylindrical block 11 of dielectric material is placed in the guide. The length and dielectric constant of the material of block 11 are such that a 180 degrees phase-shift is introduced in the radial electric component in the. lower half of the guide. On recombination of the two halves, the field pattern in that of an H11 wave. Guide 15 has a diameter which is too small to sustain an E01 mode wave, while sustaining an H11 wave. The edges of block 11 are chamfered to reduce reflection. A resonant ring 14 of the kind described in Specification 597,216 is provided to eliminate undesired modes. The block 11 may be used in a similar manner to produce an H11 wave in a circular guide when fed by a coaxial line joined end to end on a common axis (Figs. 8 and 9, not shown). Fig. 6 shows an arrangement for converting a plane polarized H11 mode wave into a circularly polarized wave. A dielectric plate 16 is diametrically disposed in the guide at an angle to the electric vector e4 such that after passing the plate, there exist two equal electric vectors e5, e6 at right angles, thus providing a circularly polarized wave. The above devices are also applicable to rectangular wave-guides.
