Patent GB-211108-A (GB)
Title: The manufacture of new sulphurized compounds of phenols
Filed: 1924-01-02
Abstract: The sulphurized phenol derivatives described in the parent Specification are converted into others, which are probably thiosulphonic acids, by treatment with an alkali sulphite preferably in presence of oxidizing agents such as oxygen, air, or hydrogen peroxide.  The products, like the parent materials, are mordants for basic dyestuffs and are also tanning agents. According to examples (1) phenol is boiled with sulphur and caustic soda solution and the viscous product diluted with water, neutral sodium sulphite added, and air passed through for several days at 70-80 DEG  C. (2) the product from o-chlorphenol, caustic soda, and sulphur, is similarly treated with neutral sulphite in a current of air until a dilute test portion dissolves on boiling; the products are isolated by acidifying and salting out.  Other phenols which may be used are o-, m- or p-cresol, crude cresol, p-chlorphenol and oxybenzoic acids.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the treatment with sulphites of the products of reaction of sulphur chloride on phenol.  This subject-matter does not appear in the Specification as accepted.ALSO:The sulphurized phenol derivatives described in the parent Specification are converted into others, which are probably thiosulphonic acids, by treatment with an alkali sulphite preferably in presence of oxidizing agents such as oxygen, air, or hydrogen peroxide.

Patent GB-805942-A (GB)
Title: Improvements relating to the preparation of urea crystals
IPC: C07C273/16
Filed: 1956-01-04
Abstract: In the preparation of urea crystals from aqueous solutions having a concentration of at least 80 weight per cent of urea by propelling the solution through a vessel (or series of vessels) wherein the water is evaporated, a surface-active agent is added to the solution in such quantity that the material passes through the evaporating vessel(s) in the form of a thick froth.  With urea solutions having a concentration of 90 weight per cent or more, the evaporation of water can take place by means of the heat of crystallization, i.e. no external heat being applied.  In an example, a 90 per cent solution of urea at 107 DEG  C. was fed at 400 kg. per hour through a vessel (length 4 m.) provided with a bladed shaft, which was rotated at 77 r.p.m.  There was also fed into the vessel 1.65 kg. per hour of a 16 per cent solution of the sodium-sulphate ester of lauryl alcohol. The vessel was filled with a thickly-frothing, slowlymoving mass; and dry crystals of urea were discharged.  About 54 per cent of the crystals had a size greater than 1 m.m.; and 38 per cent had a size between 1.0 and 0.5 m.m.  Other frothing agents referred to are the sodium salt of an alkyl - aryl - sulphonic acid, sodium stearate, lauryl pyridine chloride, and alkylphenyl polyglycol ether.

Title: Improvements in and relating to high frequency signalling systems
IPC: H04L27/04
Filed: 1923-01-04
Abstract: 191,390. British Thomson - Houston Co., Ltd., (Assignees of Baker, W. R. G.). Jan. 5, 1922, [Convention date]. Thermionic oscillation generators; keying and modulating apparatus.-The grid circuit of a thermionic oscillation generator comprises a leak resistance shunted by a condenser, and a tuned oscillatory circuit in which oscillations are generated independently of any retro-active coupling. Oscillation is normally prevented by a series condenser which interrupts the leak path and allows the grid to attain a considerable negative potential. Signals are sent by shortcircuiting this condenser, thus, allowing the valve to oscillate. The operation of signalling also closes the plate supply circuit. Alternating current is used for heating the filaments and for supplying rectifiers which energize the plate circuit. A pair of valves and a pair of rectifiers may be used, and the failure of the filaments of either is indicated by a lamp or an audible signal. The Figure shows a pair of oscillating valves 1, 2 with their filaments 3 supplied in parallel from a transformer secondary 6, earthed at its mid-point. The plates 4 are connected in parallel through a high-frequency choke coil 32 to two rectifying-valves 19, 20 connected as a full-wave rectifier to the transformer secondary 21. The grid circuits include separate coils 17, 18, a common grid leak 16 shunted by a condenser 15, a tuned oscillatory circuit 13, 14, and a series condenser 12. The operation of the signal key 37 closes a switch 38 in the primary circuit of the plate supply transformer 21, and also closes a switch 35 in a low-resistance circuit across the condenser 12. The negative charge on the grids is thus allowed to leak away until its negative potential is sufficiently reduced for the valve to oscillate. The oscillations are produced in the tuned grid circuit 13, 14 by virtue of the negative resistance accompanying the secondary emission from the grids. Amplified oscillations are transmitted to the aerial 30, an adjustable part of the aerial tuning inductance 29 being connected between the plates 4 and earthed filaments 3. A condenser 31 prevents short-circuiting of the plate supply current. The continuous waves produced may be interrupted by a rotary switch 34 in the leak path. Failure of the filaments of the oscillating valves 1, 2 or the rectifying valves 19, 20 is indicated by a lamp 41 or audible signal device 44 connected across points in the filament leads which are at equal potentials so long as both filaments are intact, but are unbalanced when either filament is broken. The tuning switches 47, 48, 49 are preferably operated jointly.
