Title: Coated articles and method of making the same
IPC: D21H19/52
Filed: 1929-01-11
Abstract: 303,898. British Celanese, Ltd., (Assignees of Dreyfus, C.). Jan. 12, 198, [Convention date]. Processes.-Articles or sheets are coated by applying thereto layers or coatings of powders, consisting of mixtures of finely-divided organic derivatives of cellulose and one or more plasticizers with or without fillers, dyes, dyestuffs, pigments and effect materials, and subjecting to heat and pressure to form adherent coatings. The plasticizers may include camphor substitutes, high boiling solvents, softeners, gelatinizing agents or mixtures thereof. The powders may be prepared as described in Specification 282,723, [Class 70, Indiarubber &c.]. The following examples of the production of powders are given :-(1) 80 lbs. cellulose acetate of an average fineness of 6-8 mesh is put into a pebble mill with 800 lbs. 1¢ to 2 inch flint stones and ground for 6-8 hours, after which is added 24 lbs. triacetin and 4 lbs. diethyl phthalate and grinding continued for a further 8 hours; (2) 80 lbs. cellulose butyrate of 6-8 mesh is ground as in (1) and 10 lbs. triacetin, 10 lbs. diethyl phthalate and 6 lbs. tricresylphosphate added and grinding continued as in (1); (3) to 80 lbs. cellulose ethyl ether of 20 mesh ground as in (1) is added 20 lbs. of dibutyl phthlate and grinding continued as before. For a white composition, 75 lbs. zinc white is added to the above mixtures followed by further grinding for several hours. The powder is applied to the surface to be coated and the article &c. placed in a press and subjected to a temperature of 50-80‹ C. and a pressure of 300-500 lbs. per square inch. Surfaces with a high polish are obtained by using moulds or presses having surfaces of glass, nickel, &c. The invention is applicable to sheets, plates, slabs, wire, rods, or cores of any shape for producing automobile body parts, furniture, &c. The surface to be coated may be of wood, metal, pottery, glass, cardboard, leather, synthetic resins of phenol-aldehyde type, &c. Paper or fabrics such as cotton, wool, silk, hemp, flax and artificial silk may be coated. Glass substitutes are formed by applying the coating to a wire cloth or screen. Phonograph records are formed by applying the powder to a suitable core. Gum may be used to secure temporary adhesion of the powder to the surface. To secure the coatings to glass or metallic sheets, the latter are perforated, roughened, grooved, recessed or formed with threaded or undercut holes to anchor the coating. The cellulose derivatives include esters. such as the acetate, formate, propionate or butyrate and ethers such as methyl, ethyl and benzyl cellulose. The invention does not include powders produced by incorporating the ingredients under the action of heat, e.g. by melting, or powders containing volatile solvents. Specification 249,600, [Class 70, Indiarubber &c.], also is referred to.

Filed: 1968-01-11
Abstract: 1,164,402. Combustion chambers operating under pressure. ESSO PRODUCTION RESEARCH CO. Jan. 11, 1968 [Feb. 6, 1967; June 5, 1967], No. 1602/68. Heading F1L. [Also in Division H4] A seismic wave source for marine use, of the type in which a combustible fluid is detonated in an expansible chamber, is provided with a passage through which fluid-flows to cool the detonation products. In the Fig. 15 embodiment the chamber is defined by an elastic sheath 61 (e.g. of rubber or neoprene) clamped at 44, 62 to cup-shaped members 75, 63. A cylindrical assembly of parallel metal tubes 51 supports sheath 61, the tube outer walls being sealed to members 75, 63. When the source is towed through the water, water flows between member 75 and a coaxial cupshaped member 77, flows through tubes 51, and emerges from member 63. An oxygen/propane or oxygen/acetylene mixture, introduced via hoses 19, 21, check valves 37, 39 and mixing chamber 41A into member 77 is detonated by spark plug 50 to inflate sheath 61 and thereby generate seismic waves. An exhaust valve 45 comprising a closure member spring-loaded against a seat vents combustion products to the atmosphere via hose 27, the closure member being of high inertia to allow sheath 61 to expand appreciably before venting occurs. The supply of combustible gases and the energizing of spark plug 50 are synchronized with the operation of a seismic wave recorder. Alternative embodiments, in which the number of cooling tubes 51 and the shape of the combustion chamber are modified, are described and details are given of towing arrangements for the source.

Patent GB-667074-A (GB)
Title: Process for obtaining lactams from aqueous solutions
Filed: 1950-01-23
Abstract: A method of working up aqueous solutions containing lactams includes the steps of extracting the lactam with the melted cyclic oxime from which it is derived and subjecting the lactam-containing oxime to Beckmann's re-arrangement.  By this means quantities of lactam remaining in the neutralized sulphate liquors from the Beckmann process are recovered and re-used. These liquors are preferably extracted whilst still hot and any oxime which may remain dissolved therein is recovered by precipitation on cooling.  Oximes with 6-11 carbon atoms in the molecule are preferred, e.g. cyclohexanone-, suberone-, cyclooctanone-, cyclononanone-, cyclodecanone-, and cycloundecanone-oxime used for recovering capro-, oenanthol-, o -aminooctylic acid-, o -aminononylic acid-, o -aminodecylic acid and o -amino-undecylic acid lactam respectively.  Aqueous solutions containing unchanged lactam from the conventional polymerization to polyamides may be similarly treated and are preferably added to the aqueous sulphate solutions.  Preferably extraction is effected in counter-current.  In examples: (1) an ammonium sulphate solution containing caprolactam is extracted at 80 DEG  C. with water and molten cyclohexanone oxime, some of the latter compound being recovered on cooling the aqueous liquors to 20 DEG  C., and the lactam-containing oxime is treated with oleum at 115 DEG  C., added to a cyclohexanone oxime re-arrangement mixture which has already reacted, neutralized with ammonia and the lactam isolated; (2) is similar to (1) except that the solution is one of sodium sulphate containing caprolactam; (3) illustrates the countercurrent extraction at 80 DEG  C. of an ammonium sulphate solution containing caprolactam with cyclohexanone oxime and in (4) an ammonium sulphate solution containing caprolactam and an aqueous caprolactam solution from the extraction of the crude polyamide are mixed and extracted at 80 DEG C. with molten cyclohexanone oxime which is subsequently treated as in (1).
