Patent FR-1601795-A (FR)
Title: Producing flame using a pyrophoric body
IPC: F24V30/00
Filed: 1968-12-19
Granted: 1970-09-14
Abstract: A pyrophoric body is brought to a predetermined place. During its transport, the body is kept away from active fluids capable of reacting with it. Then it is contacted with such a fluid, so that a spontaneous oxothermic chemical reaction, producing flames, is caused. Specifically, the pyrophoric fluid is a hydrogen phosphide mixture. While the source is a powdered solid body which is bonded on a support and placed in a moving liquid body.

[Also in Division C4] Polyester materials are dyed and printed using dyes of the general formula in which R and R<SP>1</SP> are alkyl radicals having one to four carbon atoms, R<SP>11</SP> is an alkyl group of one to four carbon atoms which may have a hydroxyl group, X is a hydrogen atom or a methyl group and n has the value 2, 3 or 4 preferably 2. Good dyeings are obtained when R and R<SP>1</SP> are methyl, R<SP>11</SP> is ethyl and n is 2. Dyeing is effected by heating at 95-100‹C. at atmospheric pressure or at 100- 140‹C. under superatmospheric pressure. Carriers such as aromatic carboxylic acids, phenols, aromatic halogen compounds, aromatic hydrocarbons and carbinols are used. Conventional thickeners for printing are used, after printing the material is steamed.

In a compander system Fig. 1 the original audio source is subjected to h.f. preemphasis in 10, a narrow band of frequencies is removed from the signal in filter 11, a pilot tone is added from oscillator 12 and the signal is compressed in compressor 13, having a threshold level below which no compression occurs, before transmission over the link 14. At the receiver the received signal is passed through an a.g.c. circuit 15 whose gain is controlled to restore the pilot level at the output of the a.g.c. circuit to a constant level, as detected by the pilot filter 16, the pilot signal is removed by filter 17 and the signal restored to its original spectral content by h.f. deemphasis in 18. In a modification, Fig. 2, the pilot signal is filtered out, by filter 16, at the input to the receiver and applied to an a.g.c. circuit which controls both an amplifier 22 for the pilot signal and an amplifier 21 in the normal signal chain. This arrangement is said to be more stable in that it removes the pilot signal filter from inside the a.g.c. loop.

A gyratory crusher has self-aligning roller bearings, which permit deflection of the shaft when uncrushable bodies enter the gap. As described, the crusher has a shaft 1 suspended from a head 2 carrying the usual cone 3, which cooperates with a ring 4. The shaft may alternatively be supported at the base or at any intermediate position. A vertical roller bearing 11 comprises either barrelshaped rollers 10a or cylindrical rollers 10b. The two forms are shown at the left and right hand sides of the drawing. Both forms have an inner cylindrical sleeve 13; the left hand form has an outer race 14a which provides axial restraint on the rollers 12a but there is no restraint on the sleeve 13 and the shaft can thus move longitudinally, apart from deflection accommodated by the barrel shape. In the right hand form, the outer race is formed as a ball joint 14b which accommodates deflection of the shaft.

A polyvinyl alcohol composition consists essentially of polyvinyl alcohol and 0.1 to 5% by weight, based on the weight of the polyvinyl alcohol, of an additive which is the product obtained by partially hydrolysing polyvinyl acetate in the presence of an acidic catalyst in an alcoholic solution until 20% to 70% by mole of acetate groups of the polyvinyl acetate are hydrolysed. The polyvinyl alcohol is the watersoluble resin obtained by partially or completely hydrolysing a homopolymer or copolymer of a vinyl ester in the presence of an alkaline catalyst according to a conventional method or such a polymer modified by acetalysation or urethanation to the extent that water-solubility is retained. In the examples, the additive is prepared by hydrolysing polyvinyl acetate in methanolic solution in the presence of monomethyl sulphate, dimethyl sulphate, sulphuric acid, hydrochloric acid and phosphoric acid as catalysts. A conventional polyvinyl alcohol is prepared using sodium hydroxide. The composition is prepared by dissolving the polyvinyl alcohol and additive in methanol and evaporating. The composition may be used as a protective colloid in the emulsion polymerization of vinyl acetate in the presence of water, sodium phosphate, and potassium persulphate.

Abstract: 1296831 Fuel cell system ENERGY CONVERSION Ltd 27 Jan 1970 [28 Feb 1969] 10814/69 Heading H1B Cell reversal is prevented in an electrochemical cell system using hydrogen as fuel and oxygen or air as the reactant, particularly a fuel cell system having electrodes of Pt and Ni, by providing a fluid such as nitrogen helium, argon, distilled water or, aqueous KOH, which is compatible with the electrode and which has no free oxygen, subsequent to shut down and/or prior to start up of the system. In an embodiment prior to start-up the electrolyte pump is switched on and the air compartments are purged with nitrogen before the hydrogen circuits. The nitrogen purge on the anode is then switched to hydrogen and then air is fed to the air electrodes. Anode reversal on shutdown is prevented by purging the cathodes with nitrogen before purging off the oxygen. In another embodiment wherein air is the oxidant the nitrogen atmosphere is provided by not circulating oxygen through the system at shut-down and/or start-up, so that the remaining oxygen is consumed by the leakage currents to produce a nitrogen atmosphere. Where the fluid provided is aqueous KOH which is also the electrolyte the air or oxygen sides of the cells are at least half-flooded and then the hydrogen sides may be flooded. The arrangement may be used for a matrix-type cell or free electrolyte cell and in these cases a small electrical load may be applied during such flooding which remains until start-up.
