Abstract: Polyacrylate, polyethylene, polystyrene and polyvinyl resins may be coloured by incorporating therein a pigment dye, free from water-solubilising groups, of formula:  <FORM:0851740/IV(a)/1> where R1 is a benzene or naphthalene residue, R2 is a benzene or naphthalene residue with the azo groups in the 1,4 positions with respect to each other, R3 is a naphthalene residue in which the azo, hydroxyl and CONH Pyr groups are in the 1, 2 and 3 positions respectively, n is 1, 2 or 3 and Pyr is a pyrene residue.  Blue to Bordeaux shades are obtained.  In Example (3) a violet coloured foil is made from polyvinyl chloride and dioctyl phthalate using the dye obtained by treating with 3-aminopyrene the acid chloride of the dye 1-amino-2, 5-dichlorobenzene --> 1-amino-5-methyl-2-methoxybenzene --> 2, 3-oxynaphthoic acid.  The dyes may also be added to polyvinyl chloride or acetate emulsions.ALSO:The invention comprises dyes, free from watersolubilizing groups, of formula:  <FORM:0851740/IV (c)/1> where R1 is a benzene or naphthalene residue, R2 is a benzene or naphthalene residue with the azo groups in 1, 4 positions, R3 is a naphthalene residue with the azo, hydroxy and CONH Pyr groups in 1, 2 and 3 positions respectively, n is 1, 2 or 3 and Pyr is a pyrene residue.  They are made by heating corresponding acid halides in an inert organic solvent with a monoaminopyrene, 3-aminopyrene being preferred.  Representative of components specified as corresponding to R1 are aniline and its monochlor, 3, 4, 5-trichlor-, 3-nitro-, 2-methoxy-, 3-trifluoromethyl-, 3-cyano-and 4-chloro- 2, 5- dimethoxyderivatives, aniline- 3- carboxylic acid methyl ester, toluidine, m-xylidene and 4- aminodiphenyl -41- and 2-naphthylamine -3- carboxylic acids.

Title: Synthetic plastic container and blank and method of folding same
IPC: B65D5/66
Filed: 1963-07-18
Abstract: 983,946. Making plastics cartons. C. E. PALMER. July 18, 1963 [July 18, 1962], No. 28411/63. Heading B5D. [Also in Division B8] A method of making a tubular carton from an unscored blank of synthetic plastic sheet material, Fig. 7, comprises the steps of folding bottom end flaps 16, 18 and 28 at right angles to the rest of the blank by means of a blade 50 and a resiliently deformable die pad 48, Fig. 8, and then folding the blank longitudinally by means of a rotatable mandrel 68 and a system of resiliently deformable pads 66, Fig. 10. At the same time, fingers 76 and 78, 82 (not shown), press tongues 22 on flaps 16 into slots 20 and a locking tongue 26 on flap 28 into slot 24 to close the carton bottom and the carton is closed longitudinally by fingers 80, Fig. 13, which press locking tongues 14 on a side extension flap 12 into slots 4 in side wall 2. The preferred material e.g. bi-axially oriented polystyrene of between 5-15 mils. thickness, is such that when cold-folded through somewhat more than 90 degrees, any inherent relaxation characteristics are compensated for and a permanent right-angle fold is formed. This is achieved in the present invention by placing the blade 50 at an acute angle to the main portion of the blank and using a mandrel having undercut portions 72, Fig. 10, which co-operate with the pads 66 on rocker supports 54, 56, 58 and 60. The slots 4 and 24 are each formed by a pair of S-shaped slits and a transverse interconnecting slit and the tongues 14, 26 are so shaped that after insertion they form a tamperproof lock. The top of the carton is closed by flaps 30, 32, Fig. 7, folded by means of a folding plate and cooperating die supports having resiliently deformable pads (Fig. 17, not shown). The tuckin flap 36 may be replaced by an above-described tamperproof tongue and slot connection. U.S.A. Specification 2,954,725 is referred to.

Title: Improvements in centrifugating apparatus for separating the components of a gaseous mixture from each other
IPC: B04B5/08
Filed: 1966-06-24
Abstract: 1,100,539. Centrifugal separators. SOCIETE D'EXPLOITATION DES MATERIELS HISPANO-SUIZA. 24 June, 1966 [5 July, 1965], No. 28504/66. Heading B2P. A centrifuge for separating a mixture of gases. e.g. isotopes, into components comprises a cell 1, Fig. 1, rotatable about its axis XX and into which the mixture is introduced into an intermediate region of the cell at a distance both from the axis XX and from the periphery of the cell, the heavy gaseous component being collected from a peripheral zone P and the light gaseous component from an axial zone A of the cell. As shown, the raw gas is fed through a conduit 2, passes through the annular space between a deflector disc 3 and one end 1a of the cell and enters an intermediate zone I inside the cell. The light gas is discharged through a conduit 6 and the heavy gas passes from the zone P via the annular passage 4 between a plate 5 and the other end 1b of the cell and is discharged via an annular conduit 4a. To facilitate the setting in rotation of the raw gas the interior of the cell is filled with porous material 7, in the form of a metallic sponge, metallic straw or partitioned or alveolate material, through which the gas circulates radially. Separation is preferably effected in a battery of co-axial cells arranged in series and rotating in the same direction, the arrangement preferably being such that a peripheral mixture gradually enriched in heavy gas and an axial mixture gradually enriched in light gas circulate through the cells in counter-current fashion. In one series arrangement, Fig. 1a, each of the end plates 1a, 1b of an intermediate cell 1 is formed with an annular passage through which extends an annular member having inner and outer radial flanges 3a, 5a so that passages are provided for the flow of the heavy and light gas mixtures as indicated 'by the arrows. Figs. 2 to 5 (not shown) illustrate different arrangements of a number of cells connected in series depending whether the raw gas is cheap or expensive and whether a mixture enriched in light or heavy gas is required as end product. In order to facilitate the flow of the heavy and light gas mixtures through the the battery of cells, a shaft 25, Fig. 6, extending axially through the cells carries discs 26, each housed in a cell and located close to one of the end walls 27 of the cell. Turbine blades 28 are carried at the periphery of the disc and serve to recuperate a portion of kinetic and pressure energy of the gaseous stream enriched in heavy gas to drive the disc, the heavy gas stream passing through a diffuser 28a into the intermediate zone of the adjacent cell. Suction blades 29 in an intermediate zone of the disc collect the stream of gaseous mixture enriched in light gas passing from the axial zone of the adjacent cell through a convergent collector 30 and discharge it into an intermediate zone of the cell under consideration. The shaft 25 may further be driven by a motor externally of the apparatus.
