Patent GB-403645-A (GB)
Title: Improvements in the manufacture of artificial products
IPC: D01F2/28
Filed: 1932-06-17
Abstract: Artificial filaments, threads, yarns, ribbons, foils, films, plastic masses, and moulding-powders comprise mixed esters or ether-esters of cellulose which contain not more than 10 per cent, e.g. 5--6 per cent, of aromatic acid radicle, and a substantial proportion of ether and/or aliphatic acid radicle.  The products are characterised by a high heat test.  The aromatic radicle may be the radicle of benzoic, toluic, nitrobenzoic, chlorbenzoic, cinnamic, or phthalic acid, and may be introduced by treating the cellulose with the corresponding acid chloride in the presence of pyridine, dimethyl aniline, or other base, or the process of Specification 403,646 may be employed, in which acidylation is effected by means of benzoic anhydride.  The other radicle which is present in substantial porportions, i.e. of the order of 2 to 2.25 substituent groups or more, may be acetyl, or other lower aliphatic acid radicle, or an ether radicle obtained, for example, from methyl chloride, dimethyl sulphate, diethyl sulphate, ethyl chloride, benzyl chloride, ethylene oxide, ethylene chlorhydrin, or epichlorhydrin.  The initial cellulosic material may be subjected to any desired pretreatment, for example, according to the process of Specification 249,173, [Class 2 (ii), Cellulose &c.], or by means of an acid reagent.  If necessary, further treatment to remove acid catalyst or to change the solubility characteristics of the product, may be carried out in the usual manner.  In the production of the artificial products, any suitable volatile solvent, or mixtures thereof with medium and/or high boiling solvents may be used, and also volatile or other non-solvents for the cellulose derivatives.  Filaments, threads, films, and the like can be made by dry or wet spinning processes, using for example, the processes of Specifications 340,324, 340,325, 340,436, and 340,437, and may, if desired, be subjected to after-treatments such as stretching to increase their tensile strength, as in Specifications 277,089, 323,790, [both in Class 2 (ii), Cellulose &c.], 370,430, and 371,461, or to shrinkage to improve their extension, as in Specifications 380,504, 380,505, 389,823, and 403,106, or to treatments designed to decrease their lustre, or to saponification, as for example, by the processes of Specifications 125,153 and 313,404, [both in Class 2 (ii), Cellulose &c.].  Compositions for use as plastic masses or moulding powders may contain any of the usual additions such as fillers, natural, synthetic, or semi-synthetic resins.  In an example, filaments are spun from an acetone solution of cellulose acetate-benzoate having a benzoyl value of 9--10 per cent, and an acetyl value of 46--48 per cent.  Specification 387,686 also is referred to.

Title: Improvements in and relating to the determining of the hydrogen content of series of metal samples
IPC: G01N33/20
Filed: 1965-04-23
Abstract: 1,068,215. Estimating gases occluded in metals. BALZERS PATENT-UND LIZENZASTALT. April 23, 1965 [May 14, 1964], No. 17174/65. Heading B1X. In determining the hydrogen content of metal samples by measuring at 5 the heat conductivity and pressure of the gas mixture formed (known to be N 2 , H 2  and CO) on heating the sample 3 in a furnace in a carbonaceous crucible 2 and then calculating the proportion of hydrogen in this mixture from the measurement obtained, nitrogen or carbon. monoxide is admixed to the gas prior to measuring the heat conductivity in an amount such that the total pressure of the gas mixture is at a predetermined level, so simplifying the calculation. When N 2  is to be determined in addition to H 2 , then CO is used as the auxiliary gas and when CO is to be determined in addition then No is used. A pressure responsive switch 6 connected to the heat conductivity measuring means 5 issues an impulse to a device 7 when the pressure falls beneath a pre-determined level to open a supply pipe from a N 2  or CO storage container 9. A pump 11 and associated valves 12 and 13 allow for the pre-evacuation of the whole device. The apparatus may include carbon monoxide analyser, for example an infra red absorption instrument, whereby the amount of oxygen and hence the amount of nitrogen evolved may be calculated.

Title: Improvements in or relating to wide-band omnidirectional antennas for very short wave working
IPC: H01Q21/20
Filed: 1970-04-10
Abstract: 1293612 Aerials THOMSON-CSF 10 April 1970 [15 April 1969] 17269/70 Heading H4A A wide-band aerial comprises at least one stage of four dipole planar arrays, which are arranged in a square around a mast. Each array consists of at least one pair of full-wave radiator elements which are fed in phase by a supply line and which are backed by a plane reflector. Auxiliary devices, comprising at least two elongated metal rods which are perpendicular to the surface of the reflector, are provided for each pair of radiator elements, and are disposed symmetrically with respect to said pair of elements and to said supply line. The horizontal radiation pattern of the array is modified by the auxiliary devices so that the amplitudes at angles of 45 degrees to the broadside axis are substantially half the amplitude along said axis, and diminish rapidly at greater angles. In a first embodiment, each array comprises a conductive reflector 3, Fig. 2,  carrying eight thick, shortened dipoles, of which four are shown, i.e. 41, 42; 51, 52; 61, 62; 71, 72. The distance between adjacent dipoles is #m/2 (Xm = mean operating wavelength) and their distance from the reflector 3 is #m/4. They are supplied in phase through two-wire lines comprising flat sections 8 and round sections 9. A first type of auxiliary radiator element comprises angled pieces of metal 10, 11 respectively fitted to the conductors of the feeder section 8. These are disposed symmetrically between the two dipoles of each pair, i.e. there are four for an array of eight dipoles. The dimensions h, l are each approximately #m/4, and the ends of the elements are not in contact with the reflector 3. A second type of auxiliary element comprises conductive supports 43, 44; 53, 54; 63, 64; 73, 74 of the dipoles 41, 42; 51, 52; 61, 62; 71, 72. Said supports are offset in relation to the centres of the dipoles, and the distance between a pair is of the order of γm/4. Four of the radiating units set in square formation around a mast-head and fed in phase with equal powers provide an omni-directional radiation pattern. More than one level of radiating units may be provided, and they may be mounted around an enlarged extension of the mast, to improve accessibility. In another embodiment, passive auxiliary radiator elements 12, 13; 14, 15, Fig. 3, extend upwardly from the reflector 3 between pairs of dipoles 41, 42; 51, 52 and 61, 62; 71, 72. The said auxiliary elements are of circular or rectangular cross-section. Their height is approximately #m/4 and the spacing between pairs is approximately equal to the overall length of a dipole.

Patent GB-563133-A (GB)
Title: Improvements in or relating to the production of textile materials which are sensitive towards water
IPC: D06M11/38
Filed: 1942-12-07
Abstract: A textile material having a basis of an organic ester of cellulose is subjected to the action of water and an acid which in association with water is capable both of saponifying cellulose esters and of hydrolysing cellulose, and the action is allowed to continue until the textile material has a very low or negligible wet tensile strength, but still has a substantial dry strength. The treatment may be such that the material gels, or dissolves, when contacted with water.  The process may be applied to yarns or fabrics.  The treated materials may be used in the production of parachutes for mine-laying, since in contact with sea or river water the material of the parachute may rapidly gelatinise and be dispersed.  The process may be applied to mixed fabrics, e.g. one having a cellulose acetate warp and a regenerated cellulose weft. It may be applied to selected areas only of a fabric.  The saponifying agent is preferably an inorganic acid such as hydrochloric or sulphuric acid.  After the solution of saponifying agent has been applied, the concentration of the acid in the materials may be increased by drying, and the reaction is then allowed to proceed until the desired degree of water sensitivity is attained.  Solutions of hydrochloric acid of 0.2 to 10 per cent strength in water or aqueous alcohol may be used for impregnating the materials.  Drying may be effected by exposure to air which may be cold or heated.  The dried materials may be left in contact with the saponifying agent for several days at low or warm temperature, preferably in a humid atmosphere.  Saponification may alternatively be effected by suspending the cellulose ester materials in the vapours arising from concentrated hydrochloric acid.  At the end of the treatment, the residual saponifying agent may be removed by evaporation, or by exposure of the materials to ammonia gas.
