Title: Improvements in and relating to electric steam generators
IPC: F22B1/30
Filed: 1922-01-13
Abstract: 195,470. Kermor, L. G. de. Jan. 13, 1922. Generating by electricity.-Steam generators of the type in which electrodes immersed in water are arranged so that as steam is generated the electrodes become more or less uncovered with a consequent automatic control of the current, have the electrodes mounted in a frame which is suspended from the top of the boiler when the top is removable, or is adapted to be run on rails or their equivalents into or out of the boiler when the end or side is removable. In Fig. 1 the electrodes 12 are carried by a frame comprising angle bars 10 and are insulated by porcelain members 14. The bars 10 are bolted to brackets 11 carried by the top 7 of the boiler. The boiler is provided with inlet and outlet pipes 23, 24 connected to radiators of a heating system, and a pipe connection 25 to an expansion tank whose position may be varied to vary the steam pressure. In Fig. 2 the electrodes are mounted on insulators 30 carried by a frame comprising plates 28, 27 separated by rods 29. The frame is fitted with wheels 33 and rods 28 for engaging rails 34 and guides 35 respectively.

Patent GB-698636-A (GB)
Title: Improvements in the manufacture of condensation products
IPC: A61K47/18
Filed: 1951-01-17
Abstract: Condensation products, apparently amino-esters and amino-ethers, are prepared by heating a polyglycol ether product of the formula A.(OC2H4)n.B (in which A is an aliphatic hydrocarbon chain with at least four carbon atoms, B is -OH, -ONa, -OK, or the radical of an inorganic acid, and n is an integer) with an aromatic acid or phenol or a functional derivative thereof containing in its molecule as a substituent at least one amino group or a nitro group, and converting any nitro groups present in the product into amino groups.  The polyglycolether chain may be interrupted by a divalent group or sulphur, and the amino group of the aromatic acid or phenol may be protected, e.g. by a benzal group.  The products are soluble and may be made more so by introduction of sulphuric acid radicals or polyglycol ether radicals or by peralkylation.  They form difficultly soluble products with tannin, synthetic or natural tanning agents, phosphotungstic acid, phosphomolybdic acid, phosphotungstomolybdic acid, or silicolungstic acid.  They have disinfecting, preserving, pesticidal, antiseptic, foaming, wetting, and dispersing properties. In examples: (1) dodecyl nonaglycol ether is reacted in toluene with phosphorus tribromide to give dodecyl nonaglycol bromide, which is reacted with the potassium salt of para-aminobenzoic acid; (2) cetyl decaglycol bromide is reacted with sodium p-benzolaminophenate, the benzal group being split off; (3) dodecyl nonaglycol ether is reacted with sodium in benzene and then with p-nitrobenzoyl chloride, followed by hydrogenation.

In the embodiment shown the input 10 of switch 12 receives short poles applied to the lines 3 in any programmed sequence and the information original is applied to the continuous electrode 2. A spot is illuminated at a coincidence between the scanning pulses and the information signal. The time delay intervals of each of the delay lines 3 is small with respect to the time intervals of application of the control voltages. One of the electrodes may be reflecting e.g. coated with rhodium and polished. Specifications 850,592, 851,076 and 851,077 are referred to.

Patent GB-487041-A (GB)
Title: Process for the treatment of wood
IPC: B27K3/32
Filed: 1938-01-18
Abstract: Wood is rendered more resistant to water, flames, and organisms by impregnation with alkali hydrate followed by drying and further impregnation with carbon bisulphide.  For surface treatment, the planed &c. surface is soaked with a 15 per cent solution of alkali hydrate, left to dry and then treated with carbon bisulphide by dipping or by wrapping with absorbent material impregnated with carbon bisulphide.  After evaporation of any residual carbon bisulphide the surface may be polished by sand papering.  Complete impregnation is effected by placing the wood in a sealed container under vacuum, introducing alkali hydrate solution until the wood is completely immersed and allowing impregnation to continue under atmospheric pressure; after complete penetration, residual solution is removed and any water evaporated, if desired, under reduced pressure and heat, following which carbon bisulphide is introduced advantageously mixed with another liquid, e.g. ethyl alcohol, which does not dissolve cellulose xanthate; the wood is finally dried in vacuo.  Carbon bisulphide may be applied in vapour form.  The wood may be compressed during impregnation with carbon bisulphide and may be finally dried under pressure.  Wooden articles, e.g. floor boards, weather boarding, window frames, wooden furniture, and gramophone needles may be treated.
