Title: Improvements in process of extracting volatile oils from coal gas, natural gases or other similar gases
IPC: C10G5/02
Filed: 1922-06-27
Abstract: 202,795. Ikeda, K., Isobe, H., and Okazawa, T. June 27, 1922. Oils, recovering; fuller's earth.-Gasolene, pentane, hexane, benzol, or other volatile oils or naphthalene are extracted from coal gas or natural or similar gases by passing the gas through a column of floridin or other form of acidic clay a. When the floridin is almost saturated it is heated electrically or by passing steam or hot oil through a jacket c and the stream of gas is reduced, whereby the adsorbed gasolene is vaporized and carried into a condenser d and a receiver f. The gas escapes by an outlet g. The acidic clay is prepared by kneading 100 parts with 80-110 parts of water, tearing the mass into pieces the size of a peanut or a walnut or pressing it through small holes to form rough-surfaced threads or sticks, and drying at 150-600‹ C. for about an hour.

Title: Impregnation of synthetic linear polyamide filaments with one-stage phenol formaldehyde resins
IPC: D01F6/60
Filed: 1942-12-18
Abstract: Synthetic linear polyamide filaments are impregnated with an alkaline condensed onestage phenol-formaldehyde resin dissolved in a liquid which is absorbed by, but is a non-solvent for, the polyamide; surplus solution is removed from the surface of the filaments; the filaments are cold drawn if not already in the drawn state, and are then heated until the phenol formaldehyde is fully condensed. Cresols or other substituted phenols may be used instead of phenol itself for preparing the condensation product. Ammonia, hexamethylene tetramine, or magnesium oxide may be used as alkaline catalyst.  The solvent for the condensation product may be dilute aqueous caustic soda, or methylated spirits, methanol, ethanol, or acetone.  Before or after impregnating the filaments with the phenol-formaldehyde compound, they may be subjected to a conditioning treatment with steam or hot water whilst they are supported in a desired position so that a permanent set or shape is imparted.  The treatment with phenol-formaldehyde produces filaments of lower water absorption, greater stiffness, greater resistance to fatigue, and a greater heat stability than corresponding untreated filaments.  Their stiffness is not lost so rapidly when they are immersed in water as is the case with untreated filaments.  In an example, a bundle of drawn and conditioned polyhexamethylene adipamide filaments is steeped in an aqueous solution of a one-stage phenol-formaldehyde resin for 1 day at room temperature and then washed in methylated spirits until free from surface tackiness.  The filaments are then stoved in an air oven at 120 DEG  C. for 2 hours, and allowed to cool in the air. Toothbrushes made with the treated filaments show much less deformation of the filaments after they have been in use for some months than those made with untreated filaments. Specifications 461,236, 461,237 and 504,344 are referred to.

Abstract: 516,351. Cathode-ray tubes. BAIRD TELEVISION Ltd., and JONES, V. A. June 20, 1938, No. 18257. [Class 39(i)] A cathode-ray tube has an optically transparent electrode emitting secondary electrons under the action of a scanning beam, these electrons being accelerated towards and focused on a fluorescent screen arranged on the same side of the secondary-emitting electrode as the means producing the beam. In the form shown, for giving a very bright television picture, the beam from the gun 3 under television signals scans the electrode 4, which is positive with respect to the gun anode, and the resulting secondary electrons from the transparent electrode 4 are focused by a coil 8 on to a screen 6 which is positive with respect to the electrode 4. The image on the screen may be viewed through the electrode 4 or by projection on to a screen to the left-hand side of that electrode. Alternatively, a lens may project the image on to a screen to the right of the screen 6. The electrode 4 may comprise a conductive glass, e.g. one rich in boron silicate, or it may comprise a metal with a thin oxide layer sensitized 'with an alkali metal. Alternatively it may comprise a transparent antimony-calcium alloy oxidized until its photo sensitivity is reduced to zero. Optical transparency of such an alloy is obtained by depositing a sufficiently thin layer of antimony and evaporating calcium in the known manner, the effect of the calcium being to increase the transparency of the layer.
