Patent GB-135636-A (GB)
IPC: C03B5/237
Abstract: 135,636. Curd, S. G. May 5, 1919. Glass-melting furnaces.-In a regenerative glass-melting furnace fired with producer gas, the producer gas is passed over a mixture of iron and carbon before entering the furnace to enrich and improve the heating qualities of the gas, and it is further enriched by mixing it with gaseous products such as hydrogen and carbon monoxide obtained by passing superheated steam over a similar mixture of iron and carbon. Figs. 1 and 2 show transverse and longitudinal sections of a glass-melting furnace with the invention applied thereto. The furnace comprises a melting-tank 1 separated by a perforated partition H and wall 6 from a reservoir 2. Holes G permit glass to flow from the tank to the reservoir. Gas and air ports controlled by valves are arranged on each side of the melting-tank, the air ports being in communication with reversible air regenerators C' and being provided with inspection openings 7. Air channels N below the melting-tank and vertical channels between the vertical gas and air passages at the sides of the furnace are provided for cooling the hearth and side walls. The lower part of each air regenerator C<1> is provided with a steam superheater T which supplies steam through the pipe K to the chamber beneath a grate 10 supporting a mixture of iron and carbon. When the gas and air are being supplied through the left hand parts of the melting-tank shown in Fig. 1, air passes to the furnace through the regenerator C<1> and ports R<1>, and waste gases escape through the opposite regenerator. Gas enters beneath the grate 10 and passes up through the mixture of iron and carbon to a gas chamber C communicating with the ports R. The waste gases passing through the opposite regenerator C<1> superheat the steam in the superheater T, and the steam passes up through the mixture of iron and carbon and is dissociated, hydrogen and carbon monoxide being produced in the chamber C and passing through valve-controlled pipes I to the opposite chamber C and to the furnace with the producer gas. A modified form of glass-melting tank having a central partition H' with or without perforations is shown in Fig. 4.

Title: Improvements in and relating to the conversion of polyphase currents into single phase currents
IPC: H02M5/48
Filed: 1931-05-09
Abstract: 373,766. Frequency changing; phase changing. LÍBL, O., 2, Neue Bismarckstrasse, Hermsdorf, Berlin. May 9, 1931, No. 13819. [Class 38 (ii).] In means for converting polyphase current into single phase current of lower frequency by transformers and rectifiers so arranged that succeeding phases of the polyphase current a1, b1, c1, &c. have different amplitudes and the anodes of the rectifiers are rendered conductive in such order that a single phase current wave is built up in the load circuit as indicated in Fig. 1, provision is made for introducing counter voltages into the short-circuit path produced under conditions of low power factor in the load circuit. Fig. 2 shows an arrangement in which a three-phase network R, S, T supplies current to a pair of phase multiplying transformers P1, P2 wound so as to produce secondary phases of graded amplitudes. The secondary phases are associated with the anodes of a pair of rectifiers G1, G2, the circuits of which are completed at appropriate intervals by switches S1 .. S6 operated synchronously with the supply current. The single phase load M is connected between the cathodes F1, F2 and the star points of the transformers so that one half cycle of the load current is derived from successively conducting anodes of the rectifier G1, and the other half cycle from successively conducting anodes of rectifier G2. A short-circuit path through the two rectifiers is formed when, due to a lagging or leading current, switches associated with different rectifiers need to be closed simultaneously. Circulating current is prevented, however, by causing the switches to close in such sequence that two equal voltages obtained from corresponding phases on the two transformers are in opposition in the short-circuit path.

Title: 2,4,4-trimethylpentyl silicon compounds
Inventor: JAMES
IPC: C08G77/38
Filed: 1962-04-10
Abstract: The invention comprises compounds of the formula RaR1bSiX4-2-b, where R is a 2,4,4-trimethylpentyl group, R1 is H or an alkyl group containing not more than 6 carbon atoms or an aryl or aralkyl group, X is halogen or an alkoxy or acyloxy group of at most 4 carbon atoms, a is 1 or 2, b is 0, 1 or 2, and a+b is at most 3, or total or partial hydrolysates thereof, or a polysiloxane containing at least one unit RaR1bSi<.  The silanes are prepared by the reaction of 2,4,4-trimethylpentene-1 with a hydrolysable silane containing at least one Si-H group.  Silanes in which X is alkoxy or acyloxy are conveniently obtained from the corresponding halides.  The siloxanes are obtained by hydrolysis of the silanes, or by cohydrolysis of these with other hydrolysable silanes, or, preferably, by reaction of 2,4,4-trimethylpentene-1 with linear or cyclic organohydrogenpolysiloxanes.  The addition reaction is preferably carried out in the presence of a platinum-containing catalyst, amounting to 10-6 to 10-1 gm. atoms of Pt per mole of olefin. 2,4,4-trimethylpentene-2 may be used in place of some or all of the 2,4,4-trimethylpentene-1, or a mixture consisting mainly of these may be used.  The siloxanes may contain as little as one trimethylpentyl group at one or each end of a chain, but preferably should contain at least 30 such groups per 100 silicon atoms, and often require at least one group on each atom.  The remaining organic groups may be alkyl, aryl or aralkyl.  Examples describe the use of a chloroplatinic acid catalyst, and a cyclohexene-platinous chloride catalyst in the reaction of a trimethylpentene mixture with methyldichlorosilane, trichlorsilane, and various trimethylsilyl-ended or cyclic polymethylhydrogen siloxanes.  Example 11 describes the use of an emulsion containing 95 parts of methyl-(2,4,4-trimethylpentyl)-polysiloxane, 5 parts of a finely divided silica, 0.5 parts of methylethylcellulose, 0.5 parts of sodium carboxymethylcellulose, and 1.5 parts of glycerol monostearate in 57.5 parts of water, as an antifoaming agent (see Division B1), and the use of the same organopolysiloxane with methylethylcellulose, sodium carboxymethylcellulose, a microcrystalline wax, a hydrocarbon solvent and water, in a polish.ALSO:Antifoaming agents comprise silanes or siloxanes containing at least one 2,4,4-trimethylpentyl group attached directly to silicon in the molecule.  Examples 11 and 12 describe the preparation and antifoaming effect of emulsions containing 95 parts of a methyl-(2,4,4-trimethylpentyl)-polysiloxane fluid, 5 parts of a fine silica, 0,5 parts of methyl ethyl cellulose, 0,5 parts of sodium carboxymethylcellulose, 1,5 parts of glycerol monostearate, and 57,5 parts of water.
