Abstract: 1,205,971. Explosive compositions. E.I. DU PONT DE NEMOURS & CO. 13 Sept., 1967, No. 41800/67. Heading C1D. A thickened slurry blasting agent which will detonate reliably at 40‹ F., consists essentially of water, an inorganic oxidizing salt at least partially dissolved in the water, a surfaceactive agent as a crystal modifier for the salt, a non-explosive fuel including at least 3% by weight, based on the total composition, of a carbonaceous fuel dissolved in the water, and from 5-60% by volume of small gas-filled cavities dispersed throughout the composition. Suitable inorganic oxidizing salts are alkali metal, alkaline earth metal, and ammonium nitrates, perchlorates, and dichromates. The surfaceactive agent may be anionic or amphoteric. Soluble carbonaceous fuels referred to are mono- and di-saccharides, alcohols, aldehydes, ketones, aliphatic acids, nitriles, amides, and lignin sulphonates. Insoluble fuels may also be present, for example, finely-divided coal, sulphur, iron pyrites, ferrophosphorus, and ferrosilicon. Thickening agents which may be used include tree exudates, seaweed colloids, seed extracts, starches and modified starches, and cellulose derivatives. A liquid organic compound may be added to act as an anti-freezing agent. Many specific examples of the above ingredients are given in the Specification. The gas-filled cavities may be produced by incorporating air, nitrogen, or carbon dioxide during the preparation of the composition, using a turbine or aerating mixer or a Venturi eductor, or by the generation of gas by the action of carbonates or bicarbonates on acid ammonium nitrate solutions. Alternatively, the composition may include a porous fuel such as a closed cell polymeric foam, a cellular carbonaceous material, or an expanded cereal, mineral or siliceous product; many of such materials are specified. In examples, the oxidizing salt is ammonium nitrate, together with sodium nitrate, the crystal modifier is sodium methylnaphthalene sulphonate or sodium lauryl sulphate, the soluble fuel is sucrose, dextrose, ethylene glycol, or formamide, the thickening agent is guar gum with potassium dichromate as a cross-linking agent, and the cavities are provided by agitation and aeration, or by the addition of bagasse pith, vermicu@ie, expanded cornflakes, or polyethylene foam.

Patent GB-1006029-A (GB)
Title: A method of producing a column for partition chromatography
IPC: B01D53/04
Filed: 1963-10-23
Abstract: A capillary column suitable for partition chromatography is made by filling a capillary tube with a bubble-free suspension or dispersion containing all the components of the fixed phase, closing one end of the tube and evaporating the liquid dispersant by heating the tube progressively from the open end.  The temperature of the tube after evaporation of the liquid dispersant is preferably kept above the dew point of that liquid.  The suspension which may be made using a high speed mixer or colloid mill, may comprise one or more active solid sorbents which are preferably finely divided, suspended in one or more high-boiling liquids which form a film on the particles when the coating is dried.  The tube may be filled by the application of pressure and the liquid dispersant evaporated using a vacuum.  The inside of the tube may be etched or coated with a lacquer or metal, e.g. silver, before the tube is filled with the dispersion.  In one embodiment, the liquid dispersant is evaporated simultaneously with the deformation of the tube to an elliptical cross-section using a pair of rollers one of which may have teeth.  The dispersants may be fluorinated, chlorinated and/or brominated methanes and ethanes, e.g. F3CCl; water or a low boiling chlorinated hydrocarbon, e.g. CCl4, CH2Cl2; the latter can also be used to dissolve up an active liquid, e.g. squalene, dinonyl phthalate or polyglycols (e.g. triethylene glycol), with which to coat the particles.  Alternatively an active liquid may be added to the solid before its suspension. Suitable solids for suspension are carbon black, graphitized carbon black, chromosorb, fire brick, Kieselguhr, silica gel, 5  molecular sieves, metal oxides (e.g. iron oxide and titanium oxide), cellulose, plastics and ion exchange resins.  A thickening agent such as highly dispersed SiO2 and Al2O3 may be added to the suspension.  The tube which may be of capillary size, may be made of glass or copper, and may be prepared for filling by flushing or cleaning with hydrocarbons, chlorinated hydrocarbons or alkali.  Reference has been directed by the Comptroller to Specification 834,390.

Filed: 1970-09-02
Abstract: 1276400 Particle spectrometers HEWLETTPACKARD CO 2 Sept 1970 [2 Sept 1969] 42014/70 Heading HID In an electron spectroscope for use in chemical analysis wherein X-rays from a source 12, Fig. 1, located on the Rowland circle 20 are directed at a crystal 18 to produce a monochromatic beam 22 which strikes the target 10 and produces photo-electrons which are focused by a lens 38 on the entrance of an electron spectrometer 28, the overall dispersion of the lens 38 and spectrometer 28 is made to cancel the dispersion of the monochromator, in order to reduce the contribution of the characteristic X-ray line width to the line width of the electrons focused on the detector 36. When the spectrometer comprises two hemispherical electrodes of mean radius p (as shown), this condition requires that where R is the radius of the Rowland circle, M is the magnification of the lens, # is the angle between the axis 24 and the tangent to the Rowland circle at the target, # is the angle between the plane of the target and the axis 26 of the lens 38, γ is the angle between the plane of the target and the tangent to the Rowland circle, E S  is the kinetic energy of a central electron in the spectrometer 28, and E P  is the mean energy of the photons in the incident beam 22. In practice this means adjusting the potentials of the inner electrodes 42 and 44 of the lens to keep M constant when the potential difference between the outer electrodes 40 and 46 is altered. In Fig. 1 the outer electrodes are funnel-shaped and the inner electrodes are frusto-conical. The axis of the electrodes may lie in the plane of the Rowland circle, or may be inclined to or normal to it (Fig. 4, not shown), the last arrangement being particularly suitable when the target is gaseous. In a modification (Figs. 5 and 6, not shown) the hemispherical electrodes of the spectrometer are modified to provide a conical entrance having an axis of symmetry passing through the centre of the hemisphere, and the lens comprises four pairs of conical fan-shaped electrodes having the same axis of symmetry.
