Abstract: 465,814. Sound and like records. ROUGH, J. E., and FIRTH, H. A. Aug. 8, 1935, No. 22378. Void. Convention date, Aug. 31, 1934. [Class 40 (ii)] For making a carrier for a reproducible record of sound or electrical impulses, metallic patticles are incorporated in a diamagnetic medium, the particles " having a density and width to give a magnetical or mechanical response as the metallic particles in the medium are passed through or by electrical and magnetical fields or mechanical recording or reproducing devices." It is stated that the particles may be " a ferro-magnetic alloy of ferro-cobalt or cobalt-steel, reduced to a molecular form " by any suitable reducing or breaking down process, " such as by any well-known abrasive method in combination with a liquid such as turpentine, and then treating said molecular particles to a mechanical and /or magnetical sorting process." The particles are then subjected to " a magnetical annulling process, until the polarity of the molecular particles is neutral or passive," before, during, or after the incorporation of the particles in the diamagnetic medium to form one or more tracks. The recording and reproducing is stated to be effected either electromagnetically or mechanically. As the diamagnetic material, various substances such as celluloid or the like, paper, fabric, copper or zinc may be used. A mixture of metallic particles with plastic binding material may be " force-fed into the diamagnetic medium such as celluloid during the manufacture of the latter," or the plastic mixture is fed into grooves formed in the diamagnetic medium, the whole being then pressed or rolled. The metallic particles may be incorporated in a picture film, to form one or more sound tracks thereon.

Patent GB-1016737-A (GB)
Title: Improvements in or relating to liquid heat-resistance and corrosion-resistance testing
IPC: G01N25/18
Filed: 1963-06-05
Abstract: 1,016,737. Testing thermal characteristics of liquids and corrosion resistance. OROGIL. June 5, 1963 [June 12, 1962], No. 22418/63. Heading B1X. The thermal characteristics of a liquid or the corrosion resistance of a plate is tested by establishing a temperature gradient between two regions of the plate, projecting the liquid on to the plate, measuring the temperature of the plate at a number of points across said gradient and determining the changes occurring on the surface of the plate between said regions. The invention also comprises an apparatus which in the illustrated embodiment comprises a vessel 1 for the liquid, supported in a bath 17 on a heating element 14, from which liquid is withdrawn through line 15 by pump 2, atomized at 7 in the form of a cone and projected on to plate 11 supported in tube 8 by shoulders 9, 9<SP>1</SP>. The plate is heated e.g. by resistance heating element 10, and thermocouples a-e pass signals to a recorder-regulator which controls the heater 10 to maintain the temperature gradient constant. Another part of the plate may if desired be cooled. If so desired, a constant amount of gas such as air, oxygen, or an inert gas may be admitted to the liquid before atomizaton through valve 4. The test may be continued with recycled liquid and fresh plates. The heat resistance of lubricants, heat transfer liquids and electrical insulators and the resistance of plates, e.g. of metal, to corrosive liquids, may be investigated. The surface characteristics of the plate employed may be colour, roughness, reflectance, thickness or weight of deposit, absorption of a reactant, thermal and/or electrical conductivity or electrical capacity. A method of enpressing the results is described.
Patent GB-391840-A (GB)
Title: Improvements in or relating to the cleansing of carbonaceous matter
IPC: B03B1/00
Filed: 1931-08-07
Abstract: 391,840. Washing granular materials. BRITISH COAL DISTILLATION, Ltd., (formerly LEICESTERSHIRE (L. & N.) COAL DISTILLATION, Ltd.) and MACHEN, C., 48, Broadway, Westminster. Aug. 7, 1931, No. 22424. [Class 82 (ii).] Carbonaceous material is subjected to low, medium, or high temperature distillation and is then deposited while still hot on the surface of a liquid, e.g. water, moved along the surface for a certain distance, and the floating material then lifted from the liquid preferably by means of an endless conveyer with perforated or gapped blades which dip below the surface of the liquid. To prevent the entry of liquid into the cells of the porous carbonaceous material the surface of the liquid is maintained substantially at boiling point, or the material may be partially cooled by sprays before being deposited on the surface of the liquid. In the preferred form, in which these two methods are combined, residual fuel from the distillation furnace is carried by a conveyer a up a passage c in which it is subjected to a preliminary cooling by sprays q of water or waste effluent and is then passed down a shoot d on to the surface e of water in a tank f. A revolving paddle g breaks up the fuel, the heavier particles sinking and being discharged by a conveyer o and bucket elevator p while the more buoyant particles are carried across the surface and up a sieve n by inclined perforated blades m of a conveyer h which travels parallel to the surface from the sprocket wheel j to a guide wheel k and then upwardly. Bubbles of air or other gas may be liberated below the surface by means of perforated pipes r to enhance the buoyancy of the fuel. The conveyer may have, instead of the blades m, bottomless perforated buckets in which case the sieve n may be dispensed with. The water level in the tank f is kept constant by the supply of additional water to a subsidiary tank s communicating with the tank f by an aperture u so that no disturbance occurs on the surface e, which, by this means, is maintained substantially at boiling point. The passage of the fuel across the surface of the water is so regulated that the fuel is efficiently quenched, but retains sufficient heat to expel excess water when lifted from the surface.
