Title: Method and apparatus for gas detection
IPC: G01N27/66
Filed: 1959-02-13
Abstract: 857,631. Determining physical qualities of gases. MINE SAFETY APPLIANCES CO. Feb. 13, 1959 [Feb. 19, 1958], No. 5044/59. Class 37 A method of detecting the presence of an electro-negative gas contaminant in a mixture with a non electro-negative gas comprises ionising a moving stream of the gaseous mixture and subjecting it to electric field the electron current flow being compared with that produced under the same conditions by the non electro-negative gas alone. Fig. 1 shows an apparatus for testing the presence of traces of electro-negative oxygen gas in otherwise pure non electro-negative hydrogen. The pure hydrogen gas is passed through a detector chamber 1 having inner electrode 8 and outer electrode 2, the gas being ionised by the presence of an alpha radiation source 9, for example radium, inside the tube. The current flow between electrodes 2, 8 is detected in a Wheatstone bridge circuit which may for example be brought to a null condition by adjustment of potentiometer 16. A predetermined quantity of oxygen gas is then mixed with the hydrogen and passed through the detector chamber 1 and the change in current flow between electrodes 2 and 8 is detected. In order to compensate for changes in the ambient conditions, or the presence of contaminant gases other than oxygen, the resistor 15 may be replaced by a second chamber connected either in parallel or series for gas flow with the chamber 1, Figs. 2 and 3 (not shown). An oxygen filter is then placed before one of the chambers so that oxygen is extracted from the gas passing through one only of the chambers and the difference in electron current flow between the two chambers is measured. The gas contaminant to be detected may be oxygen, hydrogen chloride, sulphur dioxide, carbon monoxide or chlorine and the carrier gas may be hydrogen, helium, neon, argon, nitrogen, ethylene acetylene or paraffin hydrocarbon. The contaminant gas may consist of a mixture of any two or more electro-negative gases and likewise the carrier gas may be a mixture of two or more non electro-negative gases.

Title: Method for solidifying liquid hydrocarbons
IPC: C10L7/02
Filed: 1937-02-19
Abstract: Liquid hydrocarbons are solidified by dispersing therein an alkaline silicate and casein and/or alginic acid, and adding a substance which reacts with the silicate to form an insoluble silicate.  Cellulose ethers, e.g. methyl cellulose may also be incorporated.  Suitable added substances are: calcium chloride mixed or not with formaldehyde, calcium nitrate, and salts of iron, copper, or barium. For example, a solution of 0,75 gm. of alginic acid, 4,0 gm. of commercial silicate of soda, and 1,25 gm. of casein, in 30 cc. of water is dispersed in 100 cc. of gasoline, and an aqueous solution of calcium chloride and formaldehyde added.  According to the Specification as open to inspection under Sect. 91, hydrocarbons or other liquids are solidified by (1) dispersing or forming therein an artificial resin, e.g. a phenolformaldehyde or urea-aldehyde resin; sodium silicate and then a calcium or like salt may be added to produce an insoluble silicate; or (2) by dispersing therein a colloid and a mineral salt which is then rendered insoluble by a suitable reaction.  Salts specified are: (1) alkaline silicates; insoluble silicates are formed therefrom by addition of salts as above; (2) soluble carbonates; these are transformed into calcium or other insoluble carbonates; (3) soluble sulphates; these may be transformed into barium, calcium, or other insoluble sulphate; (4) aluminium or other salts from which insoluble hydrates may be precipitated. Suitable colloids are alginic acid and/or casein.  This subject-matter does not appear in the Specification as accepted.

Title: Carbon black pellets for ink formulations
IPC: C09C1/58
Filed: 1969-01-30
Abstract: 1,254,961. Carbon black pellets for ink formulation. COLUMBIAN CARBON CO. 30 Jan., 1969 [1 Feb., 1968], No. 5119/69. Heading C1A.  Pellets of carbon black and oil are producedby subjecting a confined body of fluffy carbon black particles to intense agitation and thereby setting the particles into rapid, churning motion while in a dispersed state, contacting an oil pelletizing medium with the agitated particles, the oil being in the form of a micro-atomized fog of liquid particles, continuing the agitation until the particles are uniformly coated with oil and thereafter recombining the oil coated particles into a denser bed of particles and subjecting the bed to mild tumbling action until the particles are formed into pellets. The proportion of oil in the dispersion of carbon black and oil is 2-25% by weight of black. The intense agitation is accomplished mechanically or by means of a highly turbulent flow of non-reactive gas, e.g. air, and the oil pelletizing medium may be entrained within the non-reactive gas. Alternatively high velocity jets of a non-reactive gas may be used, in which the oil-pelletizing medium may be entrained. A rotary drum may be used to effect the mild tumbling action to form the coated particles into pellets.
