Title: Manufacture of metalliferous dyestuffs
IPC: C09B45/01
Filed: 1930-05-28
Abstract: Azo dyes, complex metal compounds of.--Azo dyestuffs containing one or more metals are obtained by treating unsulphonated o-oxyazo dyestuffs with elementary metals capable of forming complex compounds with the dyestuffs.  The products are suitable for incorporation in varnishes having a basis of cellulose esters or ethers or artificial or natural resins.  The following examples are specified: (1) An aqueous solution of the dyestuff 4-nitro-2-aminophenol --> resorcinol is boiled under reflux in presence of finely powdered copper; the product, sparingly soluble in water, is soluble in organic solvents such as alcohol, ethyl acetate, or amyl acetate, and dissolves in commercial nitrocellulose varnishes to a brownish orange solution giving on metal surfaces vivid brownish orange coatings, fast to light.  The treatment with copper may also be effected in presence of a neutral salt, e.g. common salt or magnesium chloride, or of an acid salt, e.g. primary sodium phosphate; a similar product is obtainable by using aluminium powder in place of the copper.  (2) The dyestuff 4-chloro-2-aminophenol --> resorcinol is treated as in (1) with aluminium powder in presence of ammonium acetate; the product colours nitrocellulose varnish orange; the dyestuffs from diazotized 5-nitro-2-aminophenol or 1 : 2- or 2 : 1-aminonaphthol coupled with b -naphthylamine, b -naphthol, or pyrazolones may be treated with metals such as nickel, cobalt, chromium, iron, or mixtures thereof to obtain products which colour varnishes orange, brown, and blue violet tints.  (3) The copper compound obtained in (1) is incorporated in a finished cellulose or artificial resin varnish; the product may be applied by brushing or spraying to surfaces of metal, glass, porous ceramic ware, leather, wood, celluloid, &c., giving a transparent orange coating fast to light; it may be converted into a matt or covering varnish by incorporating insoluble pigments or sulphates such as barium sulphate or gypsum.

IPC: G05D16/18
Filed: 1922-06-17
Abstract: 181,735. Aktiebolaget Vaporackumulator. June 18, 1921, [Convention date]. Venturi casings; indicating amount of opening. -A system of steam or gas supply under pressure in which the final pressure is above 57 per cent of the initial pressure, employs a valve, the outlet of which is formed as a nozzle of the de Laval type. The quantity of steam or gas passing through the valve is stated to be independent of the outlet pressure, and dependent only on the inlet pressure. In one form of valve, the closure member V is provided with a cone J, which, in conjunction with the expanding outlet H maintains the pressure at the throat about the critical pressure ratio, and the discharge as stated above. The valve opening may be indicated by a graduated scale M on the spindle. The valve shown in Fig. 4 is adapted to be inserted between two pipe lines at right angles. The spindle L carries a disc N which rotates in a slot O in a reciprocating slide P. The disc N and slide P are both graduated so that an accurate adjustment of the valve is possible. These valves may be employed to control the supply from a common main to a series of units such as digesters, boiling vats, dryers, &c., to maintain the comsumption approximately constant.

Patent GB-475640-A (GB)
Title: Improvements in and relating to electromagnetic devices
IPC: H02H3/247
Filed: 1937-06-25
Abstract: 475,640. Electromagnets. BRITISH THOMSON-HOUSTON CO., Ltd. June 25, 1937, No. 17779. Convention date, June 25, 1936. [Class 35] [Also in Group XXXVII] An electromagnetic device for use in an A.C. circuit comprises a magnetizable frame 16 and an armature 17 biassed to an unattracted position by a spring 18, a winding 22 energizable from the circuit for producing an A.C. flux in the frame'to attract the armature, and means for selectively opposing the flow of opposite half-cycles of the flux in portions of the frame to provide a substantially unidirectional flux in the armature. In the arrangement shown which is intended for use in an undervoltage protective system, the frame 16 is E-shaped, the operating winding 22 being wound on the middle limb 21. The outer limbs 49, 50 carry windings 51, 52 which are short-circuited through thermionic valve rectifiers 25, 26, the cathode heating circuits of the valves being supplied from a secondary winding 42 on the middle limb 21. On closing a switch 23, the winding 22 is energized and the armature 17 is attracted to close a circuit through the load 11 at contacts 14, 15. At the same time, an extension 19 of the armature engages contacts 20 to establish a holding circuit for the winding 22. The windings 51, 52 are oppositely connected to the rectifiers and oppose the flow of opposite half-cycles of the alternating flux in the outer limbs 49, 50, so that the flux through these limbs and through the armature is substantially unidirectional, and the armature will be maintained in its closed position without chattering or hum. If the voltage in the winding 22 falls, the decay of the unidirectional flux is opposed by the currents induced in the short-circuited windings 51, 52, so that the armature is maintained in its attracted position for a predetermined interval. The load 11 therefore remains connected during a momentary drop in the supply voltage, but if the drop is prolonged, the armature is released and the load is disconnected. The load may be disconnected substantially instantaneously at any time by opening a normally closed switch 24, which simultaneously opens the circuits of the windings 22, 51 and 52. Specification 441,723, [Group XXXVII], is referred to.
