Title: Improvements in and relating to envelopes for gas cells
IPC: B64B1/62
Filed: 1931-04-22
Abstract: Cellulose carboxylates, nitrates, and ethers.--Envelopes for gas cells consist of one or more layers of an organic cellulose derivative or derivatives soluble in organic solvents and one or more layers of a highly polymeric albuminous compound or compounds, such as gelatine, glue, or casein.  For small gas cells, e.g. meteorological testing balloons, layers of these kinds are sufficient, but for larger gas cells, as in aircraft, textile web is incorporated.  The web may be coated with solutions of the materials, or applied to the surface of the composite film while this is softened by heat or by a solvent or swelling agent; or the web may first be combined with a prepared single layer and then coated with a solution, or first coated with a solution and then combined with a solid sheet.  It may thus be provided with impervious coatings on both sides, or several coated webs may be combined.  Suitable cellulose derivatives are esters and ethers such as cellulose acetate, acetate-butyrate, laurate, or butyrate-laurate, ethyl cellulose laurate, ethyl cellulose, benzyl cellulose, and hydroxy-alkyl celluloses and their esters.  These preferably preponderate in the composition of the compound film. softening agents, natural or artificial resins, filling materials, colouring agents, fireproofing substances, or the like, may be added to the materials.  In an example, 45 grm. of cellulose acetate are dissolved in 255 c.c. of a mixture of 9 parts acetone, 1 of ethanol, and 1 of benzene, and to the solution are added 40 c.c. of a condensation product of acetaldehyde and glycerine and 23 c.c. of a solution of gelatine (0,5 per cent) in a mixture of 2 parts of water, 1 of methanol and 1 of acetone.  A film formed from this solution is coated with a 10 per cent solution of gelatine in aqueous acetone, to which glycerine to the amount of 30 per cent of the gelatine has been added.  After drying, another film of the first kind, or an ordinary cellulose acetate sheet, is applied.  The composite film is softened with acetone and pressed on to the web.  Cotton fabric may be placed between the gelatine layer and the second cellulosic layer. According to the Specification as open to inspection under Sect. 91 (3) (a) the cellulose derivative may be the nitrate.  This subject-matter does not appear in the Specification as accepted.

Filed: 1956-04-23
Abstract: 833,354. Arc lamps. SOC. LE CARBONELORRAINE. April 23, 1956 [April 21, 1955], No. 12428/56. Class 39(1). An electrode arrangement for high-intensity carbon arcs has the positive and negative carbons non-coaxially arranged but with their longitudinal axes meeting and has a blowing arrangement located adjacent the negative carbon having an outlet in the form of an elongated aperture or a plurality of apertures arranged in a line, the outlet being arranged and disposed to blow gas above the meeting point of the electrode axes so as to blow the anode vapours away from the negative carbon, thereby keeping the negative carbon cool. The width of the gas jet or jets in operation is approximately equal to the diameter of the stream of anode vapours to be blown back. In the arrangement shown in Fig. 1, the cathode 2 is supported by a metallic head 3 of silver or copper internally hollowedout in channels or in a chamber for the circulation of cooling fluid and the gas blowing tube arrangement 4 comprises a cylindrical tube having an inlet aperture 5 and an outlet aperture flattened in a plane perpendicular to the plane containing the electrodes 1, 2. The blowing tube 4 can be positioned above the cathode or at the side thereof. In the arrangement shown in Fig. 3 the cooled current input head 13 for the cathode 2 forms a single body with the blowing tube 14 which runs parallel to the axis of the cathode 2 for part of its length, the outlet end being off-set. The tube 14 has a single inlet aperture and the outlet end of the tube is constructed in a curved or straight elongated form or as a series of apertures in a curved path with or without an elongated aperture. The cathode 2 can be of elliptical, rectangular or square section. The sizes of the outlet apertures can be different so as to vary the outlet speeds of the gas jets and the arrangement can be such that the individual jets can be parallel to the cathode axis or tilted with respect thereto, e.g. to produce a slight convergence of the individual jets. The cooled cathode head and the blowing tube arrangement can be made in one piece by making the various ducts and cavities from a metallic mass or can be made in two pieces which are welded together. A specific example for operation at 600-650 amperes is described giving dimensions and stating that the electrodes are inclined at 135 degrees, the blowing gas is air and the cooling fluid for the cathode head is water.
